One GABA agonist drug, vigabatrin, has been tested on an animal model of tinnitus and has shown some effectiveness. This simple technique recently discovered by scientists at leading medical universities is the best way to permanently silence the noise blaring inside your ears. This study examines the outcomes of patients undergoing the Neuromonics tinnitus treatment protocol at a single, tertiary referral center over a 2-year period.
Tinnitus, defined as head noise in the absence of an acoustic stimulus, is a complex symptom affecting 40-60 million people in the United States [1]. Various questionnaires, such as the Tinnitus Handicap Questionnaire, Tinnitus Effects Questionnaire, Tinnitus Handicap Inventory, and Tinnitus Reaction Questionnaire (TRQ), have been developed as a means of quantitatively assessing the effect tinnitus has on an individual's quality of life [11-13]. This study evaluated our experience with the Neuromonics device in suitable patients from August 2007 to July 2009. All patients who initiated treatment with the Neuromonics device at our clinic between August 2007 and July 2009 were included in this study. Treatment with the Neuromonics device involves two components: soft, relaxing music of varying amplitude and a separate wideband noise similar to white noise.
At 2 months after initiation, patients repeated audiological testing, completed a new TRQ, and were subsequently transitioned to the next phase of treatment (phase 2). There was no appreciable change in hearing levels during the course of the treatment for any of the patients (data not provided). Thirteen of the 15 patients in the incomplete group returned their device within 3 months of initiation.
The average percent change in TRQ score from initial to last test was also examined as a function of the initial TRQ score. Tinnitus is not a disease but rather a complex symptom believed to result from abnormalities in central and peripheral auditory pathways. In this study, 47 patients were enrolled in a treatment protocol with the Neuromonics device over a 2-year period. Though these results provide evidence of potentially successful treatment with the Neuromonics device, there was also a large group of nonresponders. Candidacy criteria for the Neuromonics tinnitus treatment protocol have not been firmly established, though some basic guidelines have been proposed by the manufacturing company (Neuromonics Clinician's Guidelines, Client Candidacy Guide, Neuromonics Pty Ltd., Sydney, Australia). The extent of a patient's reaction to his or her tinnitus, as measured by the initial TRQ score, might be an important variable to consider when determining treatment efficacy. Though hearing considerations are certainly important in deciding on treatment strategies for patients with tinnitus, the current study did not demonstrate any differences in hearing threshold levels among those who were successful in completing the Neuromonics protocol and those who were not, nor was there a correlation of PTA to percentage change in final TRQ score. We thank Lonneke Heuvelmans, AuD, and Nicole Greene, AuD, for their assistance with this project. Clinical medicine teaches that the key to achieving positive treatment results for any diagnostic category of patient complaints is based on the clinical establishment of an accurate diagnosis. The definition of tinnitus, originally defined as the perception of a sound unrelated to an external source of sound stimulation (1979), is considered to be dynamic, reflecting advances in what is and is not known of the cochleovestibular system and brain function. A tinnitus-targeted therapy (TTT), a combined treatment of medication and instrumentation focusing on pharmacotherapy, has evolved from an ongoing clinical experience since 1977 (in more than 10,000 patients with SIT 1. Briefly, the identification of principles of tinnitology for diagnosis and treatment of SIT patients has evolved from our ongoing TTT experience since 1977. At this time, the principles of tinnitology are divided into those for diagnosis (Table 1) and treatment (Table 2).
Our clinical experience with the MATPP has been the development of a rationale for establishing an accuracy in tinnitus diagnosis and attempting tinnitus relief 1,9.
Critical for both the SIT patient and tinnitus professionals attempting tinnitus relief is to be aware of the realities of the state of the art of tinnitus diagnosis and treatment at this time.
The following definitions are considered significant in reporting results of modalities of tinnitus treatment and relief. The medical significance of a symptom or disease process in a patient is defined as "a clinical manifestation of abnormal function of a living cell, tissue, organ, or organ system(s)" 4.
Treatment of a symptom or disease is "the management or care of a patient or the combating of a disease or disorder. Tinnitogenesis is a seizure-type activity resulting in the perception of an aberrant auditory stimulus (tinnitus) 12. The sensory component of tinnitus refers to the subjective perception of the sensation of the aberrant auditory stimulus-tinnitus-as described by tinnitus patients.
Clinical types of SIT have been identified based upon the clinical history and metabolic and electrophysiological correlates of brain activity and cochleovestibular function.
Neurodegeneration, in this report, is a term "reflective of process(es) involved in the progressive damage or death of neurons and reflected clinically in a gradual deterioration and interference in function of the affected neural substrates of the nervous system" 17,18. Neuroprotection refers to "processes involved in the maintenance and repair and restoration of normal neuronal function" 17-19.
The final common pathway (FCP) for tinnitus has been hypothesized for all clinical types of tinnitus. The tinnitus dyssynchrony-synchrony theory is a hypothesis that considers tinnitus to be an abnormal, conscious, auditory percept.
We present an update on TTT, a combined treatment of medication and instrumentation focusing on pharmacotherapy 1.
The clinical course of tinnitus, particularly SIT, is highlighted by its individuality and chronicity. To appreciate clinical advances that have been made for tinnitus diagnosis and treatment since 2006, it is necessary to briefly review the past.
Clinically, however, tinnitus is still considered by many professionals and patients to be a unitary symptom. The recent publication of the Tinnitus Research Initiative (TRI) database has recognized the clinical reality that tinnitus is not a unitary symptom 25!
The classic site of lesion audiometric hearing threshold testing of 250 Hz-kHz is recommended in tinnitus patients to be extended to include the ultra-high frequencies of 10 to 20 kHz. For patients with either unilateral or bilateral tinnitus and an asymmetrical sensorineural hearing loss, completion of tests of auditory brainstem response or magnetic resonance imaging (or both) of the brain and internal auditory canals with gadolinium is recommended to identify the presence or absence of acoustic tumor.
The incidence of SEH occurrence in our experience continues to be approximately 35% overall.
Evaluating tinnitus includes identifying its psychophysical and psychoacoustical characteristics, cochleovestibular testing, and masking curves 28.
Supplemental testing with auditory brainstem responses, nuclear medicine brain imaging with SPECT and PET, and quantitative electroencephalography (QEEG) are reserved for SIT patients resistant to conventional modalities attempting relief. A special clinical type of a predominantly centraltype SIT has been identified in a cohort of SIT patients with cerebrovascular disease, epilepsy, and memory and cognitive disorders, reflecting neurodegenerative disease 17,18. Masking is a term used to refer to the effect of one tone or one sound on another tone or sound or combinations thereof 35.
Auditory masking, the replacement of one source of acoustic stimulation by another, a "covering up" or "blockage" of one sound by another, is a normal function of the auditory system. Tinnitus treatment recommendations continue to focus on identifying the tinnitus etiology and on the conceptualization of the past that tinnitus is a unitary symptom. Although no tinnitus cure is available in our experience for patients at this time, protocols of combined treatment modalities that are available attempt to provide accuracy in diagnosis and identifying the medical significance of the tinnitus and tinnitus treatment, relief, and control 9,40. The neuro-otological consultation focus is on the clinical history, clinical course of the complaint, neuro-otological physical examination, and review of past medical records. Hypotheses of the role of biophysiological mechanisms in producing tinnitus are selected for translation to the attempt to establish accuracy for the tinnitus diagnosis and attempted treatment. The selection of a particular modality of treatment is individualized for each patient and differentiated between the components of the tinnitus (see Figs.
Basic pharmacotherapeutic management principles have been followed since 1979 1 (see Table 6). Instrumentation is recommended to tinnitus patients resistant to pharmacotherapeutic modalities for attempting tinnitus relief, approximately 10% to 15% since 2000.
Step 2: Removal of keratotic debris and cerumen from external canal and tympanic membrane as appropriate. In our experience, a majority of the patients report significant tinnitus relief and control after completing steps 1 to 4 and do not require instrumentation. Innovative receptor-targeted therapies (RTT) based on identification of the underlying neurotransmitter systems 37. Titration of gabapentin should begin at the lowest possible dose: The goal is to do no harm. A psychiatric consultation is recommended for evaluation and treatment of associated anxiety and depression or both and to consider the drug Klonopin if no medical contraindication (see Table 4). Step 6: Tinnitus patients, predominantly central type, resistant to attempts tinnitus relief in steps 1-5 are recommended instrumentation in consultation with audiology. Transcranial magnetic stimulation (TMS) research protocols have reported significant short-term tinnitus relief 48,49. In general, the results of surgery, both clinical and as research protocols for tinnitus relief, have increased since 2006. Significant tinnitus relief with intratympanic steroid therapy has been reported for a predominantly cochleartype tinnitus 51,52. We look to the future for advances in the discipline of tinnitology for tinnitus theory, diagnosis, and auditory neuroscience of sensation and brain function to provide translation for development of new and increased efficacy of existing modalities of therapy for all clinical types of tinnitus. These advances will reinforce the alteration in the paradigm of thinking of tinnitus, as recommended in 1983, from a focus on the ear and the psychoacoustic and psychophysical characteristics of the tinnitus to that of the ear and associated multiple brain functions as reflected clinically in the heterogeneity of tinnitus at this time.
In summary, we look forward to the pharmacological evolution of tinnitopharmaco-proteogenomics, defined as pharmacology for tinnitus based on what is known of the genetic diversity and protein functions demonstrated by tinnitus patients with different clinical types of tinnitus.
We hypothesize that future identification of epilepsy genes can provide an insight into the molecular basis of neuronal excitability and brain function, which will have application for a particular central-type tinnitus.
For surgery, we look forward to expansion of intratympanic drug delivery systems, with a focus on hearing conservation, which we predict will result in increasing degrees of reported tinnitus relief.
Alternate therapies will report in the future an increased significance for tinnitus relief with cognitive therapy and acupuncture as an accompaniment of anticipated advances in understanding brain function. The MATPP is presented as a dynamic neurootological-audiological protocol reflecting advances in tinnitology and neuroscience; it provides increased diagnostic accuracy, a monitoring system for all clinical types of tinnitus, and translation for increased efficacy of tinnitus relief.
A paradigm switch for clinical thinking of tinnitus is recommended to concentrate on brain function responses to an aberrant dyssynchronous auditory sensory input and in particular consciousness and affect, respecting the psychophysical and psychoacoustic characteristics of the tinnitus.
A biochemical marker, the GABA-A receptor, that has been identified provides translation for treatment, called RTT-GABA, of a predominantly central-type tinnitus.
Tinnitus is the perception of sound in the ears or head that isn’t caused by an outside source. Having tinnitus can have a major effect on many aspects of your life including relationships and work.
Clinical hypnotherapy can help you learn to manipulate the sound itself so that you can take control and change its nature, pitch and tone. Cutaneous digital blood flow (CDBF) during electrical promontory stimulation was measured by laser Doppler flowmetry in 46 tinnitus patients. Our results suggest that relief of tinnitus was closely related to increased parasympathetic nerve tone. Our objective is to show that our electrical treatment for tinnitus could cause increased parasympathetic tone in tinnitus patients with tinnitus suppression. We used LDF to assess the effects of treatment in 46 patients with tinnitus (46 ears) who received electrical stimulation treatment at least three times between September 1994 and March of 1995.
The stimulation array was placed on the promontory through a small incision made in the ear drum after local anesthesia with iontophoresis.
Laser Doppler Flowmetry (LDF) was used to monitor blood flow of the tip of the second finger of the right hand using a laser Doppler flowmetry monitor (Laserflow, BPM 403, TSI Corp.).
Figure 2 shows a representative LDF pattern observed in patients with no relief of tinnitus. Electrical stimulation is sometimes associated with an acoustic effect that is similar to the effect produced by a tinnitus-masking device) In the present study, however, tinnitus was relieved without perception of sounds although higher frequency (up to 20 kHz) electrical stimulation evoked cochlear nerve activity even if lower frequency electrical stimulation caused stronger response of cochlear nerve activity.8 In addition, there has been no report that tinnitus suppression produced increased parasympathetic nerve tone. In addition to tinnitus suppression, we reported that some patients with implanted electrical tinnitus suppressor fell asleep on a bed during stimulation,12 suggesting that ES using a 10 kHz sinusoidal wave induced sleep. The Siemens Micon hearing aid and Phonak's Audeo Q provide built-in tinnitus programs that mix with the sounds created by an individual's tinnitus and reduce its level of annoyance.
How to cite this article Shulman A, Strashun AM, Afriyie M, Aronson F, Abel W, Goldstein B. Single Photon Emission Computed Tomography (SPECT) of brain with technetium- 99m hexamethyl propyleneamine oxine (Tc-HMPAO) is an imaging technique which has been introduced for the identification of abnormalities of regional cerebral blood flow (rCBF) in patients with a central type of subjective idiopathic tinnitus, which was characterized as severe and disabling. Neurotologic and neurologic implications are suggested which include cerebrovascular disease, neurodegenerative disorder and dementia, and neuropsychiatric mood disorder. Tinnitus is a perceptual disorder of auditory function clinically identified to have both sensory and affect components. SPECT imaging technique of the brain is an objective analytical detection method which provides information on regional cerebral perfusion of the brain. Previously reported analytic localization techniques for tinnitus have included electrophysiologic testing for cochleovestibular function including auditory brain stem response for the recording of auditory evoked potentials.12 SPECT provides a measurable regional metabolic correlation. Organicity of brain in tinnitus patients was first reported in a preliminary study of 10 patients, who, upon completion of an MATPP, were identified to have a predominantly central type tinnitus. Two representative cases are presented to illustrate the organicity observed in patients with a central type of tinnitus and to speculate on the implications of SPECT in neurotologic and neurologic disease, as exemplified by cerebrovascular, diseases, neurodegenerative and neuropsychiatric mood disorders. The single-photon cerebral perfusion tracer (Tc-99m HMPAO) was used in all patients in this SPECT study. Triad, that is, a state-of-the-art, tripleheaded, Anger-type gamma camera with a dedicated computer for acquisition and processing-was used to acquire a 64-frame, 3600 study.
Raw data used for quantification of brain SPECT regions of interest in the three orthogonal planes of examination (i.e. Normal brain SPECT studies in the preliminary study13 demonstrated bilateral symmetrical activity in anatomic regions of interest of cortical and central gray matter (Fig.
The finding of a relatively normal deposition in the subcortical areas, motor strip cortex, and cerebellum was judged significant.
Neuropsychologic evaluation questioned cognitive impairment; a borderline function range was impaired for fundamental tasks of visual perception, visual span and attention, visual reasoning, visual problem solving, and visual memory. The original tinnitus onset was in 1944 after exposure to artillery in the United States' Marine Corps, and described as right ear ring. A combined program of tinnitus control was followed, based on differentiation between its sensory and affect component.
The findings reported in SPECT of brain performed on two patients with tinnitus of the severe disabling type reflect ongoing clinical experience with this technique. Auditory function can be considered to involve multiple neural networks reflecting various attributes of hearing.13 Asymmetries identified by this imaging technique may represent interruptions of normal auditory function as reflected in variations in right cerebral blood flow (CBF) that affect multiple neural networks. Central attributes of hearing may be represented by multiple areas of the cortex now identified in part as CBF asymmetries in SIT patients with predominantly central tinnitus.
Both are speculated to be reflected in the multiple areas of cortical asymmetries as demonstrated in this studr: and reported in the initial SPECT report.
Identification of attributes of tinnitus in different ROIs of brain and their attentional modulation in patients with tinnitus of the central type could provide a basis for increased accuracy of tinnitus diagnosis and its clinical application for treatment. Identification of the affect component of severely disabling tinnitus using SPECT demonstrates impairment in rCBF in specific regions of interest known to be related to mood and memory. The medial temporal lobe system was identified to have a memory function.17,18 Reciprocal connections are presumed to exist between the hippocampus and adjacent anatomically-related cortex, including endorhinal, perirhinal, and parahippocampal cortices. As new information adds to our understanding of the anatomy and function of the limbic system, the medial temporal lobe system studies of memory, perception, and mood can be applied to the affect component of tinnitus.
It is also hypothesized that the technique of SPECT imaging of those areas of the cortex SPECT Imaging of Brain 25 and subcortex previously identified may provide clinical manifestations of mood alteration and its relationship to a paradoxical auditory memory as reflected in asymmetries of rCBF. The affect component of the symptom of tinnitus reflects the emotional response of the patient to the presence of tinnitus.20 Emotional responses are reflected in the neurobiologic processes occurring in the brain. The multiplicity of asymmetries in various ROIs examined in brain with SPECT imaging when correlated with present knowledge of neurotransmitter function underlying a dysynchrony in neural firing within and between neural networks suggest types and subtypes of a central tinnitus. Neurologic implications for tinnitus patients are suggested by the findings of perfusion asymmetries with SPECT imaging of the brain. SPECT can differentiate between Alzheimer's disease and some other types of dementia including multi-infarct dementia, hydrocephalus, progressive supranuclear palsy, and various frontal lobe dementias. Neuropsychiatric disorders including the schizophrenias, and the affective disorders, including depression, can be demonstrated with SPECT imaging of the brain.
It has been hypothesized that there is a specific link between the thought disorder present in schizophrenia and pathologic sites in the left temporal lobe.23 The degree of thought disorder is suggested to be related to the size of the reduction in volume of the left posterior superior temporal gyrus.
SPECT studies of affective disorders including major depressive disorders show an overall decrease in regional rCBF especially in the frontallobes.26 This pattern is reported to be different from that seen in dementias.
Significant involvement of hypoperfusion particularly in the frontal lobe areas has been demonstrated in our preliminary study and present case reports. Case 1 demonstrated perfusion asymmetries in the posterior parietal, temporal, and anterior frontal lobes, with a relatively normal deposition in the subcortical areas, motor strip cortex, and cerebellum. Case 2 is considered to reflect patterns seen in cerebrovascular disease and the mood disorder of depression.
The heterogeneity of the clinical manifestations of tinnitus are considered to be reflected in the SPECT of brain imaging results obtained in our series to date and demonstrated in the two reported cases.
Brain SPECT results in a particular central type SIT patient may reflect a complexity of dysfunction in neuronal networks resulting from an altered state of excitation which results in a dysynchrony in neuronal signaling, with the place of origin in the primary auditory cortex.
Tinnitus, defined as a basic dysynchrony in neuronal firing within the cochleovestibular system, may specifically result in a paradoxical auditory memory center in the hippocampal amygdala complex, and other portions of the limbic system may result in varying degrees of abnormality in affect ranging from mild anxiety to severe depression.
In short, varying degrees of glutamate neurotoxicity involving neuronal networks leading from the primary auditory cortex to areas of brain function for auditory memory and affect may underlie the heterogeneity of the symptom of SIT. No conclusion has yet been arrived at with respect to association between SIT and a cerebrovascular, neurodegenerative, and some neuropsychiatric disorders.
SPECT imaging of brain in a patient with SIT is considered a significant advance for the neuroscience of tinnitus diagnosis. Appreciation is extended to the Lionel Hampton Ear Research Foundation for its support of this effort.
A retrospective review of patient records was performed with the objective of collecting demographic and audiological information and identifying changes in score on an established tinnitus questionnaire (Tinnitus Reaction Questionnaire [TRQ]) after treatment.
Though the precise etiology in most cases is unknown, an abnormal interaction between peripheral and central auditory pathways is believed to play a role in tinnitus development [2].
The TRQ has been used extensively in research protocols and is useful as a means of measuring a change in a subject's tolerance of tinnitus [2,11]. Historical, demographic, and audiological information was reviewed, and the percent change in TRQ score was calculated for those patients completing the treatment course. A total of 47 patients underwent the initial assessment and went on to receive the Neuromonics device. At different stages in the treatment protocol, the white noise is added or taken away to help mask the tinnitus or aid in desensitization, respectively.
Each patient completed the TRQ, a 26-question survey designed to measure patient attitudes and thoughts about their tinnitus over the previous week (Table 2). The audiologist set the minimum volume of the device, determined the levels for use at different stages in the protocol, and discussed device usage and management with the patient. Again, they were asked questions regarding the level of interaction with their tinnitus and any relief experienced up to this point.
The broadband masking threshold, loudness discomfort levels, and residual inhibition levels were retested. Chi-square was used to compare categorical variables between groups, and analysis of variance was used to test differences between group means.
Table 3 shows the mean TRQ scores for each of the three groups and all patients at each test interval.
Significant research efforts have been undertaken over the last two decades to better understand the causes of tinnitus and to examine the effects of various proposed treatments [3,4,14-17].
Fifteen of the 47 patients (32%) enrolled in the treatment protocol eventually returned their device and did not complete treatment. Unlike those with a specific disease process, patients with tinnitus need not necessarily go through a series of progressively more involved treatments.
In the current study, we found no significant correlation between final percent change in TRQ score and initial TRQ score, although patients with initial TRQ scores higher than 26 had a larger percentage reduction in TRQ score (see Table 4). Hearing aids must still be considered a valuable and successful therapy for patients suffering from hearing loss and tinnitus and should be discussed as a treatment option for appropriately selected patients. Though research efforts continue to try to understand the mechanisms and causes of subjective tinnitus, new treatments are being developed to aid those suffering from this difficult problem. As far as we know, people’s tones vary across a broad spectrum of human hearing in frequency. These sounds include whooshing noises, rustling sounds, and sounds that are difficult to describe (and since they, by definition, exist only in subjective awareness, they are hard even for the people who have them to reproduce for others).
Background: The completion of a MATPP has been recommended since 1977 for each tinnitus patient in an attempt to establish an accurate diagnosis.
The term tinnitus in this article refers to subjective idiopathic tinnitus of the severe disabling type (SIT).
Tinnitology is an integrated multidiscipline of basic science, neuroscience, and clinical and nuclear medicine used in an attempt to understand an aberrant auditory phenomenon unrelated to an external source of sound and how it becomes transformed into one of affect.
Principles of diagnosis and treatment for SIT have evolved from the TTT experience, which provide a rationale for attempting tinnitus relief.
The clinical application is resulting in a significant increase in the efficacy of modalities of therapy available for attempting tinnitus relief for all clinical types of tinnitus. Repetitive findings both from the clinical history and the MATPP in this combined neuro-otological-audiological approach for SIT are the basis of what we identified initially to be principles of tinnitology 1,4; (see Tables 1 and 2).
Anything that lessens tension or strain, or offers a pleasing change as to the mind or eye 10.
Its identification provides an objective basis for an innovative anti-seizure medication attempting tinnitus relief for a predominantly central SIT. They are (1) the sensory component (sensory stimulus), (2) the affect component (behavioral response to the sensory stimulus), and (3) the psychomotor component (the motor response to express the behavioral response to the sensation) 13. The affect component of tinnitus refers to the emotional response of the patient to the sensory component.


Tinnitus is believed to originate as an initial dyssynchrony in pre- or postsynaptic neuronal transmission within the peripheral or central nervous system (cortical or subcortical).
All have visited the tinnitus clinic at the Downstate Medical Center of the State University of New York (DMC-SUNY) and the Martha Entenmann Tinnitus Research Center, Inc.
Our clinical experiences for both tinnitus diagnosis and treatment since 1977 were summarized in 1991 and updated in 2006.
The principles of diagnosis and treatment (see Tables 1 and 2), , and modalities of treatment available at the present time (see Tables 3-5), are presented not as menu-driven recommendations for tinnitus treatment, control, and relief but rather as a selection based on a rationale targeting hypothesized underlying biophysical processes.
A paradigm change is recommended in clinical thinking both for the symptom itself and for the response to treatment.
At this time, tinnitus is considered clinically to be a symptom, heterogeneous in its etiology, clinical course, and clinical manifestation as different clinical types. Algorithm for tinnitus diagnosis and treatment: the medicalaudiological tinnitus patient protocol. The original concept of clinical types of tinnitus (CTT) 23 is considered to be fundamental for translation to any and all attempts for tinnitus relief. The establishment of this data base will be a significant advance for both diagnosis and translation for an increased efficacy for any and all modalities of therapy attempting tinnitus relief and control. Tinnitus patients with hearing thresholds within the range of "normal" (250 Hz-8 kHz) have been found to have elevated thresholds in excess of what is expected for their age.
These modalities are used in the attempt to improve the accuracy of the tinnitus diagnosis and provide a monitoring system for evaluating the efficacy of therapeutic modalities aimed at tinnitus, which included control of factors influencing the clinical course of the tinnitus and a previous trial of instrumentation 33,34. Identifying and treating this particular central-type SIT has been accompanied with relief. Itard 23,35 believed that utilizing external sounds to interfere with the tinnitus was the most effective relief procedure.
Algorithms of the final common pathway (sensory, affect, psychomotor components) and tinnitus treatment. The brain functions associated with each component of the aberrant auditory sensory stimulus (tinnitus) are integrated in each algorithm with the involved neuroanatomical substrates. The clinical course of SIT, a stressor, becomes clinically manifest with increased severity by a reduction in the inhibitory activity of the GABA-A receptor, which is deficient and cannot inhibit the aberrant auditory signal 7.
A menu-driven approach is that of the majority of tinnitus professionals for recommendations of instrumentation, medication, or surgery.
The MATPP has provided our team with a basis for the selection of existing modalities of treatment with resultant increased efficacy of tinnitus treatment, relief, and control, which we have called a tinnitustargeted therapy (TTT) 1, 9. We have focused on masking, glutamate neuroexcitotoxicity theory, inhibition, benzodiazepine deficiency, neurodegeneration, neuroprotection, calpain theory of apoptosis, kindling, long-term potentiation, lateral inhibition, epileptogenesis, stress, neurotransmitter action at synaptic levels of activity and alteration in the homeostasis of function between the fluid compartments of ear and brain 5,12,20-22,37, 41 For the associated compliant of hyperacusis, a plan for sound attenuation utilizing white noise is recommended.
The goal is pharmacological short-term tinnitus relief therapy, but planning must be made for long-term benefit. If the clinical type of tinnitus is a predominantly cochlear type, intratympanic drug therapy with steroids, preceded by computed tomography of the temporal bones is recommended 43. If the clinical type of tinnitus is a predominantly the central type, innovative drug therapies are recommended. There should be some indication of involvement of the CNS before use of an innovative application of AEDs 9,16,33,37. Tinnitus relief with auditory cortical stimulation has been reported 53 as has the surgical application of a cochlear implant in a tinnitus patient 54. Cortical brain approaches with extra- or intracranial TMS (electrical stimulation), alone or in combination with drug therapies, will offer to patients with predominantly central-type tinnitus an increased degree of efficacy for tinnitus relief.
A "cure" for tinnitus is the ultimate goal of both tinnitus patients and all professionals involved in tinnitology. Tinnitopharmacolgy and tinnitopharmacoproteogenomics is the future for pharmacotherapeutic treatment of different clinical types of tinnitus.

Increased Parasympathetic Nerve Tone in Tinnitus Patients Following Electrical Promontory Stimulation.
The study group included 26 men (26 ears) and 20 women (20 ears) ages 42-79 years (mean: 61 years). A representative laser flowmetry pattern in a patient who experienced complete relief of tinnitus. Mean CBFR did not differ significantly (p>0.4) between patients with sudden deafness and patients with deafness of unknown origin. Percentage ratio of cutaneous digital blood flow as a function of change in tinnitus suppression. Therefore, the mechanism of relief following electrical stimulation was not the same as that associated with a tinnitus-masking device.
Falling asleep may be the supreme relaxation, suggesting that our method for ES may be a kind of relaxation therapy in addition to masking by improvement of hearing loss which was shown by our preliminary report.9,10 Our method of using the electrode through the hole on the ear drum was so stressful that some patients actually seemed to feel comfortable after the cessation of the stimulation. However, electrical stimulation did not affect cutaneous digital blood flow in guinea pig, suggesting that increased CBF in this study is probably not caused by the same mechanism causing increased blood flow to the cochlea. However, the discrepancy between subjective findings and LDF assessment in five patients, who reported complete tinnitus suppression and did not feel comfortable, was observed. One of our goals for tinnitus suppression by ES is to extend the duration of residual inhibition.

It may be a tone or a noise, a roar like a seashell roar, a chirp, hiss, or click or a combination of these. SPECT results of brain demonstrate for the first time the in vivo significance of the organicity of brain for a central type of tinnitus. Clinical types of tinnitus have been identified with a Medical Audiologic Tinnitus Patient Protocol (MATPP).1 The MATPP is a unified diagnosis and treatment strategy for tinnitus.
Cerebral blood flow has been correlated with function.2-8 In the determination of local brain function, the variables to be considered are cerebral blood flow (CBF) and cerebral metabolic rate (CMR). Quantitative SPECT can potentially provide measures of structure and function, which can assist in both the diagnosis and monitoring of therapy. Cross-sectional images of radiotracer distributions were analyzed and provided a direct measure of regional organ function of the brain. The finding of relative normal deposition in the subcortical areas, motor strip cortex, and cerebellum was of interest. Electrical high frequency audiometry revealed positive responses of 1000 to 3000 Hz, absent at 3000 to 20000 Hz to the limits of the audiometer 60 dB sound pressure level (SPL).
Residual inhibition was measured binaurally at 10 dB re threshold of the matching 9000 Hz tone and then a 9000 Hz narrow band noise. Computerized tomograph scan of head and brain performed in 1986 was reported to be negative. The neuropsychologic profile was most consistent with significant right hemisphere abnormalities. The parameters of tinnitus identification were described to have a quality of a high ring; ear in location, bilaterally left greater than right, constant duration, and fluctuant intensity.
For the sensory component, tinnitus control initially included treatment of a presumpted secondary endolymphatic hydrops left for 4 to 6 weeks, with a trial course of systemic vestibular suppressant anti-histamine medication and diet-in the elimination or control of salt intake. Our position is that central attributes of hearing may have as one of its symptoms of dysfunction not only interference in sound perception and speech discrimination, but also tinnitus. It would also provide a means for correlating a specific pathology with a specific physiologic attribute of tinnitus and thus lead to the development of a neuropharmacologic approach for tinnitus of a central type(s). Clinical manifestations of alterations in the sensorium of tinnitus patients include stress, anxiety, and depression. PET and SPECT both measure regional blood flow which reflects biologic markers of local neuronal activity. The two cases discussed in this paper support such implications and suggest the need for further investigation. The typical finding in Alzheimer's disease is a bilateral parietotemporal hypoperfusion and hypometablism, with sparing of the sensory motor and occipital regions. In schizophrenia, the most consistent finding has been a decrease in frontal lobe size, that is, hypofrontality, and increased rCBF in the basal ganglia, specifically the caudate, often associated with positive symptoms such as delusions and hallucinations. Postmortem CT and MRI studies have indicated that patients with schizophrenia have anatomic abnormalities in the left temporal lobe, and also that positive symptoms are related to an enlargement of the left sylvian fissure. Such findings have been reported typical of a pattern seen with dementia of the Alzheimer's type. TInnitus in this patient may be a soft sign of gradually progressive cerebrovascular disease.
The distribution of cortical asymmetries in the frontal, partial, temporallobes and in particular the limbic system suggest the possibility of a neurologic basis for tinnitus particularly of the central type.
Such glutamate receptors mediate excitatory neurotransmission in the brain and are important in memory, speech and sound acquisition, learning, certain neurodegenerative disorders, neuronal plasticity, and neurotoxicity.
Interference in glutamate neurotransmission is considered to interfere in neuron plasticity which is regulated for memory by processes of long-term potentiation (LTP) in the hippocampus and long-term depression (LTD) in the cerebellum.24 Both of these fundamental processes are considered to underlie information storage in the brain. In any single patient, this neurotoxicity may be a forerunner of progressive degenerative diseases (including Alzheimer's disease), neuropsychiatric mood disorders, schizophrenias, cerebrovascular disease, and other central neurologic pathologies.
Such a conclusion awaits neuropathologic confirmation with attention to the demonstration of a neuropathologic correlate. This is the first time that objective asymmetry in cortical perfusion in multiple areas of brain, consistently in the left temporal lobe, has been demonstrated in consecutive tinnitus patients clinically identified to be of the predominant central type.

Many of you will at some time or other have tried at least one form of complementary therapy, or alternative medicine, as a way of helping your tinnitus. Forty-seven patients initiated treatment with the Neuromonics device during the study period. Various therapies have been proposed for the treatment of tinnitus, including the use of masking devices, hearing aids, cognitive behavioral therapy, habituation programs, acupuncture, transcranial magnetic stimulation, and various herbal and vitaminbased supplements [3-10]. We hypothesize that the Neuromonics device can aid in tinnitus desensitization and lessen patient symptomatology and, thus, is a unique therapeutic option.
All patients were referred by physicians in our clinic to audiologists within the clinic specializing in tinnitus treatment. There was a wide range of duration of tinnitus prior to using the Neuromonics device, with the majority of patients having had tinnitus for 5 years or less.
Treatment with the Neuromonics device is designed to be received through the use of individual earphones. For each question on the TRQ, a score from 0 to 4 is possible, with a total TRQ score that may range from 0 (no bothersome tinnitus) to 104 (maximally bothersome tinnitus).
At 2 weeks after the initial assessment, patient use time was uploaded from the device to a computer. At this point, patients were counseled to turn the volume of the device down so that they could hear their tinnitus 60% of the time and the music the remaining 40% of the time (with the device on) for desensitization purposes. Paired samples t-tests were used to evaluate the difference in initial, final and initial, and second TRQ scores, whereas independent samples t-tests were used to examine differences between patients with and without prior treatment. Nine patients felt that the device was of no help, whereas four patients felt it made their tinnitus worse.
Table 4 shows the breakdown of mean change to last test by group and initial score category.
Recently, a customized acoustic stimulus delivery system, the Neuromonics device, was introduced as a means of promoting neural plasticity within the auditory system in hopes of minimizing or abolishing tinnitus-related symptomatology [2,14].
The average reduction in TRQ score for this group was 62%, similar to that found in earlier studies [2]. Most reported that the device was of "no help" and felt that the device may have made their tinnitus subjectively worse. Consequently, the Neuromonics protocol may prove equally effective in patients who have and have not tried other treatments. This is not unexpected, as individuals with TRQ scores of less than 26 likely represent patients who are less affected by their tinnitus and consequently are less likely to have a substantial change in their symptoms with any treatment modality. Further studies will be necessary to determine whether there is a minimum threshold level that is required for patients undergoing treatment with the Neuromonics device, because issues related to maximum device amplitude may arise with more profound hearing losses. The Neuromonics tinnitus treatment protocol was designed to target both the auditory and behavioral components involved in an individual's perception of tinnitus.

A tinnitus-targeted therapy (TTT), a combined treatment of medication and instrumentation focusing on pharmacotherapy, has evolved from our ongoing clinical experience since 1977 (now in excess of 10,000 SIT patients) [1-4].
It is believed to originate as an initial dyssynchrony in pre- or postsynaptic neuronal transmission within the peripheral or central nervous system (cortical or subcortical).
All patients visited the tinnitus clinic at the Downstate Medical Center at the State University of New York (DMC-SUNY) and the Martha Entenmann Tinnitus Research Center, Inc. Future advances in tinnitology are expected to add to, subtract from, or modify the principles of tinnitology as set forth in this manuscript. The psychomotor component of the tinnitus refers to a patient's motor response accompanying the emotional and subjective perception of the sensation of the aberrant auditory stimulus (tinnitus). They have been identified as involved in sensory processing underlying cochleovestibular function (peripheral and central) and in the neuroscience of brain function.
Since 1979, our team has continued to report the clinical identification of clinical types and subtypes of tinnitus, particularly for a predominantly central-type SIT. These findings provide a basis for understanding the heterogeneity in the quality of the tinnitus as described by tinnitus patients and for the future potential application for attempting tinnitus control.
The ultra-high frequency findings, when positive, have clinical application for both diagnosis and treatment 28,29. These factors include cerumen in the external auditory canal with or without tympanic membrane involvement, fluctuating aeration in middle ears, SEH, noise exposure, stress, metabolic abnormalities in glucose, cholesterol, triglyceride or thyroid function, and hypertension with or without fluctuation and occurring either alone or in combination. Such drugs include the vasodilator papaverine for cerebrovascular insufficiency, clopidogrel bisulfate (Plavix) in transient ischemic attack and poststroke patients, and anti-seizure drugs for epilepsy. The FCP proposes clinical consideration of auditory masking to be predominantly a brain function with peripheral and central components.
The reciprocal interacting neuroanatomical substrates of the three components complete a circuit-the final common pathway sensory-affect transformation. All patients are interviewed by telephone prior to receiving the appointment and are requested to have undergone a complete physical examination within 6 months prior to neuro-otologicalaudiometric consultation and to provide past hearing and balance testing, imaging and pharmacological record results, and a short narrative of the clinical course of the tinnitus for review.
The clinical types of tinnitus in this group are predominantly of the middle ear and cochlea, alone or in combination. Ultra-quiet therapy utilizing ultra-high-frequency stimulation has provided tinnitus relief in a particular cohort of SIT patients , however is not available at this time 47.

Incapacitating unilateral tinnitus in single-sided deafness treated by cochlear implantation. Since tinnitus can also be exacerbated by stress, we will show you ways that you can use to help you control noise relief and not to feel so stressed. In contrast, patients in whom treatment did not suppress tinnitus experienced no change in digital blood flow. Sympathetic stimulation constricts cutaneous blood vessels but increased parasympathetic tone dilates cutaneous vessels.6 Laser Doppler flowmetry (LDF) is a conventional method for measuring cutaneous blood flow. The wire was connected to a stainless steel lead wire that was attached to an electromagnetic coupling system.
The symbol "o" represents the mean value of the cutaneous digital blood flow at the onset of stimulation and the symbol "+" represents the mean value at the end of stimulation. The number of patients in each etiologic group was too limited to permit a comparison between responsive and unresponsive ears.
Open circles showed values of ratio of cutaneous digital blood flow in 14 patients who felt comfortable and filled circles in 32 patients who did not feel comfortable. In patients with slight tinnitus suppression, only the three patients with larger CBFR felt comfortable. Our previous report9 showed that response of auditory-evoked magnetic field response was augmented following ES in tinnitus patients with relief of tinnitus. However, we did not let patients know the time of stimulation so that the expectancy of cessation of stimulation and pulling the electrode out could not make the parasympathetic nerve tone increased. Increased cholinergic nerve tone dilates the cutaneous vessels, suggesting that parasympathetic tone in tinnitus patients who experienced increased CBF may be augmented by ES. The CBFR in these five patients was similar to that detected in patients who reported little or no relief, suggesting a placebo effect. We found that there was a close correlation between effectiveness and increased parasympathetic nerve tone. Preliminary report from articulation test of grammatically correct but non-sense Japanese 4-segment sentences. Two typical cases are presented which demonstrate significant regional abnormalities in cerebral perfusion bilateral of temporal, frontal, parietal and hippocampal amygdala regions when compared with normative Tc-HMPAO SPECT of brain data.
These patients were seen for initial consultation in the Tinnitus Clinic of the Health Sciences Center at Brooklyn-State University of New York and referred for this examination. SPECT data may reflect the physiologic test mapping of the metabolic rate of cerebral function for a particular region of interest.
An HMPAO dose of 25 mCi was administered intravenously in patient 1; and 23 mCi in patient 2, while the patient was at the basal-physiologic state, that is, with eyes and ears open. Perfusion images of the brain were obtained with a spatial resolution of 6.8 mm in the plane of the slice.


Our normative qualitative data were obtained in five patients with hearing within normal ranges for speech frequencies. Tonal testing revealed negative residual inhibition on the right and a rebound effect on the left.
The tinnitus intensity index rating was 6 on a 0 to 7 scale (0 meaning no tinnitus and 7 greatest severity). The intensity was described as severe and has become left greater than right for at least 3 to 5 years before the initial consultation. Reduction in recruitment and control of dysequilibrium was followed by a trial of instrumentation. In a small proportion of Alzheimer's patients, SPECT abnormalities can be primarily unilateral and correspond with signs of unilateral functional disturbances found on neuropsychologic tests.
Three major findings reported by Shenton and colleagues23 are (1) lateralized left-sided decrease in gray matter in the anterior hippocampus- amygdala, parahippocampal gyrus, and superior temporal gyrus with an associated increase in the temporal hom of the lateral ventricles; and (2) a strong correlation between the degree of thought disorder and decrease in volume in the left posterior superior temporal gyrus, a region previously acknowledged to be significant as a neuroanatomic substrate for language,24,25 and (3) a statistically significant correlation between volume reduction and neuroanatomically interconnected temporal lobe regions, which may be important in performing auditory associative memory links.
A decrease in cognitive function was reportedly delayed years fol-lowing the onset of tinnitus in this patient.
The clinical history of an associated memory disorder accompanying intensification in tinnitus may be reflected in the hypoperfusion of the temporal lobes.
The identification of subtypes of a central type tinnitus await future identification of a neuropathologic correlate which can only be accomplished by the scoring of neurons in brain, ganglion cells in the organ of Corti, and other factors. Tinnitus of the severely disabling type as demonstrated by SPECT imaging of the brain, may in some patients be a soft, and key symptom or sign of organic brain disease.

Fourteen patients completed treatment, and another 18 were actively undergoing treatment at the end of the study period.
Though some of these treatments have proven beneficial for select patients, a definitive treatment for tinnitus remains to be discovered. Patients subsequently completed a tinnitus history questionnaire that included demographic information and information about prior ear surgeries, duration of tinnitus, affected ear(s), any prior treatments aimed at tinnitus relief, and any history of medical problems or comorbid conditions. Discussion about device use ensued, and questions regarding interaction with the treatment and relief obtained were asked and recorded. During phase 2, the wideband noise was dropped completely, and the patient listened only to the relaxing music during Neuromonics use. They were also instructed to decrease use of the device to 2-4 hours per week and, eventually, to use it only when needed (maintenance phase).
Pearson correlation coefficients were computed to examine the relationships between PTA, initial TRQ, and percent change in TRQ. The few patients in the lowest initial TRQ score category had the smallest average change, but score categories beyond that showed little difference. Preliminary data reported on the use of the Neuromonics device have shown that more than 80% of patients achieve clinically significant reduction in their tinnitus, defined as a greater than 40% reduction in tinnitus disturbance as measured by the TRQ [18].
Moreover, 11 of 14 (78.6%) had a greater than 40% reduction in TRQ score over the course of the treatment, a definition for success that has been used in prior studies [2]. The average initial TRQ score for this group was 53.9, a value that fell between the average initial scores for the completed and active groups. Most patients in this study received some form of prior treatment, but the mean percent reduction in TRQ score for patients in the completed group without any prior treatments (n = 4) was not significantly different from that of those with prior treatments (n = 10). We also found no significant correlation between initial TRQ score and duration of use of the device. Its specialized acoustic stimulus targets the effects of auditory deprivation while its relaxing music is intended to reduce involvement of the limbic and autonomic nervous systems in the perception of tinnitus. Principles for SIT treatment have evolved from the TTT experience that provides a rationale for attempting tinnitus relief. It interferes in the excitatory and inhibitory process or processes involved in maintaining homeostasis for brain neurofunction in multiple neural substrates and acts as an aberrant auditory stimulus to express this dysfunction via the auditory system 5. It is expected that these principles will be expanded and modified to reflect future advances in tinnitology. Neuroanatomical substrates that have been identified in brain contribute to an evolving pathophysiology for all clinical types of tinnitus.
According to the definition of tinnitus, the perception of tinnitus is a central function in all CTT . Particularly significant for tinnitus is the finding of a labyrinthine asymmetry that, when correlated with the symptom of ear blockage and a positive Metz test for recruitment, provides the basis for the clinical diagnosis of a secondary endolymphatic hydrops (SEH) 30. Identification, treatment, and maintenance of normal aeration of the middle ears, when identified and treated, have resulted in tinnitus relief and control in approximately 15% of our SIT patients.
For memory and cognition, we recommend the neuroprotective drugs donepezil hydrochloride (Aricept), Cognex (tacrine), memantine hydrochloride, gabapentin, and clonazepam (Klonopin). The manifestation of the symptom of tinnitus is considered to be a reduction in the normal auditory masking function in the brain: The neuroanatomical substrates are hypothesized to involve the cochlea, the brainstem, the thalamus, and multiple cerebral cortices (Figure 2). Similarly, tinnitus relief, when reported, is clinically considered by our team to reflect a return of adequate masking. Second, drug selection should take into account agents that have a short half-life so as to minimize the incidence and duration of side effects. The dose for the sensory component is based on the tinnitus intensity index (TII) and the tinnitus annoyance index (TAI), both on a scale from 0 to 7.
The cutaneous digital blood flow of patients who experienced slight relief did not differ significantly from patients who experienced no relief. Therefore, changes in the blood flow of the skin during ES could be easily detected by LDF. In the 20 patients with bilateral tinnitus, ears with louder tinnitus were chosen to be assessed. A plate electrode for recording the electrocardiogram was attached to the post-auricular skin. The difference in the mean hearing level between responsive and unresponsive ears was not significant (p>0.1).
A dotted line shows the summated value of the mean ratio of cutaneous digital blood flow and the two standard deviations (113.8%) in patients without tinnitus suppression. We also showed10 that word recognition was improved following ES in tinnitus patients with relief of tinnitus. The gradual increased cutaneous digital blood flow following the start of stimulation, as shown in Figure 1, suggested that ES actually acted on the parasympathetic nerve. The mean CBFR in the group that was only slightly suppressed did not differ significantly from the group with no relief.
Therefore, we should focus more on the relationship between the autonomic nervous system and tinnitus relief to understand the mechanism of the residual inhibition.
In this way SPECT reflects local neuronal activity.9-11 The availability for SPECT of specific receptorbinding radio tracers, which bind at a specific particular site of lesion within the CNS, may thus be identified.
Narrow band masking curves were performed and yielded Type IV distance curves ipsilaterally and contralaterally. Laboratory work including complete blood count, sequential multiple Analyzer Computer (SMAC) 25, thyroid examination, fluorescent treponemal antibody (FTA)-all reported normal.
Associated complaints included bilateral hearing loss, with left greater than right, bilateral ear blockage left worse than right, early memory dysfunction, and an occasional positional dysequilibrium. The tinnitus patient may develop a memory not only for normal auditory stimuli but also, paradoxically, for the aberrant sound, that is, tinnitus. This report stresses that it is not known whether similar features are present in patients with other diagnoses such as mood disorders with psychosis or in patients with a first episode of schizophrenia, in whom the potentially confounding effects of chronicity and medication may not have occurred. Neuropsychologic testing demonstrated inter-ference in cognitive function, which raises the question as to whether or not in this patient and in others with similar patterns of cortical asymmetry, the tinnitus may have such a medical significance. Treating tinnitus naturally involves diagnosing the condition, trying auditory therapy and being open to other methods. 4) Sesame seeds: Sesame seeds is rich in zinc and has been used in oriental and eastern medicine systems for the treatment of tinnitus.
The Neuromonics tinnitus treatment protocol (Neuromonics Pty Ltd., Sydney, Australia) is a relatively recent therapeutic option that was developed to target both the auditory and behavioral components involved in an individual's perception of tinnitus [2].
The completed group consisted of 14 patients who completed the 6- to 8-month course of treatment with the Neuromonics device.
Although the incomplete group appeared to have a larger percent of patients in this long-duration category, there were only a very small number of such patients (n = 3), and the difference from the other two groups (each n = 1) was not statistically significant. Pure-tone audiometry with supraaural headphones was performed at inter-octave frequencies from 250 to 8,000 Hz, with additional highfrequency testing from 10 to 12.5 kHz.
During this phase, the background wideband noise was consistently present while the intensity of the relaxing music was periodically altered.
We also examined initial TRQ score and percent change in TRQ score at last test as a function of reported duration of tinnitus symptoms (Table 5). However, owing to its recent introduction, there are a limited number of studies evaluating the therapeutic effectiveness of the Neuromonics device in clinical practice. The two additional groups in our patient population were those patients who were still actively undergoing treatment at the end of the study period (active group) and those who returned their device (incomplete group). There is a need for continued research to examine whether a single treatment modality or multiple treatment methods, either simultaneously or in succession, is necessary for optimal relief of tinnitus. That is, initial score was not predictive of who found the device of no help and gave up its use early. Based on the results of our study, the Neuromonics device appears to be useful as a means of significantly reducing the effects of tinnitus on an individual's daily life. Understanding the pathophysiology of this transformation in brain is considered to be fundamental to diagnosing and treating tinnitus of all clinical types.
The CTT are identified by the correlation of the clinical history, physical examination, electrophysiological correlates of cochleovestibular function, and an evaluation of metabolic and electrophysiological activity in brain.
Visual suppression of the vestibuleocular reflex, a sign of cerebellar dysfunction, is significant for the identification of a central component for the tinnitus and involvement of the acousticomotor system 31.
These drugs may influence the SIT by improving the underlying neuronal anatomic substrate(s) that may be contributing to SIT 1. The cerebellum, via the acousticomotor system, has reciprocal projections to and from the somatosensory cortex, IC, thalamus, PAC, and parietal lobe [18].
We recommend selection of RTT-GABA for patients with SIT of more than a year's duration and a diagnosis of a predominantly central-type tinnitus based on completion of the MATPP.
In H Feldmann (ed), Proceedings of the Third International Tinnitus Seminar, Munster, 1987. The ratio of CDBF before and after treatment did not correlate with patient age, audiogram pattern. Stimulation was initiated at 50 μA for 60 seconds, about 30 seconds after the stimulator was switched on. Measurement was not done at the first stimulation trial because insertion of the electrode through the tympanic membrane was so stressful. The most common audiogram pattern was slightly sloped and consistent with that for a high-frequency sensorineural hearing loss (n=17). These findings are related to Shulman's comment" that tinnitus may be masked secondary to the improvement of hearing. Counting statistics for each ROI were derived by standard methods, and expressed as the mean number of counts. Associated complaints included ear blockage greater on left than on right, dysequilibrium, and cognitive and memory deficits.
The vestibular test battery (computerized rotary chair and pursuit tracking test) was clinically interpreted as a primarily central oculomotor dysfunction; with a reduced vestibular response of the peripheral vestibular labyrinth right. This is interpreted to indicate that although the tinnitus was maskable, an intensity level of at least 20 dB above the threshold would be needed to produce this effect. For the affect component, psychiatric consultation for control of anxiety and depression included therapy with carbamazepine and clonazepam, with amitriptyline and flurazepam for sleep.
A trial of Trental therapy for the central component was recommended for persistence of tinnitus.
15 It can be speculated that a short-term memory is established for tinnitus in the medial temporal-lobe memory system which becomes stored in associated areas of the neocortex.13,15 A paradoxical memory for tinnitus may cause the tinnitus to become clinically manifest as a severely disabling tinnitus. Namely, can be consider the presence of tinnitus, which precedes dementia, to be an early marker of aneurodegenerative disorder, with its initial focus in the primary auditory areas of the temporal lobe and tinnitus is the primary symptom? You should not use the information on this web site for diagnosing or treating a health problem or disease, or prescribing any medication or other treatment. Of those who completed the treatment, the mean posttreatment TRQ score was significantly lower than the pretreatment score ( p ~ .001). This therapy involves the use of a specialized acoustic stimulus aimed at targeting the effects of auditory deprivation and relaxing music to reduce involvement of the limbic and autonomic nervous systems in the perception of tinnitus.
The active group consisted of 18 patients who were actively undergoing treatment but had not yet completed the planned course at the end of the study period.
Most of the patients (72%) had reported trying prior treatments, including hearing aids (n = 8), maskers (n = 10), music (n = 9), vitamins (n = 11), biofeedback (n = 2), tinnitus retraining therapy (n = 1), and other therapeutic options (n = 7). The number of patients in any one group and duration category are too small for statistical analysis, but there appears to be a tendency for those with a very short duration of symptoms to show the most improvement. Of all patients with at least one follow-up TRQ, 75% had a greater than 40% reduction in TRQ score.
Nevertheless, it will be important to delineate which candidates are more likely to benefit from treatment with the Neuromonics device, and initial severity of symptoms is a factor warranting further study. Future clinical studies are needed regarding the precise candidacy criteria and longer-term efficacy of this novel treatment device.
When viewed in terms of sensory processing, the FCP hypothesis is considered to be expanded and broader in its application for all sensations, normal or aberrant 8,20. Critical for attempting tinnitus treatment, control, and relief for any and all clinical types and subtypes of tinnitus is the clinical establishment of accuracy for the tinnitus diagnosis 14,24.
Again, the accuracy of the tinnitus diagnosis is the key to selecting modalities of treatment in attempting tinnitus treatment, relief, and control. Hyperpolarization and depolarization of GABA-influenced thalamic neuron activity results in thalamocortical oscillations in a synchronous signal at brain cortex [204,254]. Plans should be made for longterm treatment, particularly for the affective behavioral component. The next most common audiogram illustrated a sharply sloping, high-frequency sensorineural loss pattern (n=9). Therefore, these findings may suggest that tinnitus suppression by ES may be caused by a kind of central masking mechanism. This suggests that tinnitus suppression was not sufficient to increase CBF in patients with slight response or, alternatively, placebo responses are most likely in this group. Significant past history included antecedent psychiatric history with hospitalization in 1986 and 1987 for depression, a sleep disorder stated by the patient to be related to tinnitus, and periodic marijuana use in 1970 to 1972.
The neurotologic diagnosis was based on correlation of the clinical history, cochleovestibular test battery, neurotologic examination, and tinnitus evaluation identified tinnitus to be primarily of the central type with a cochlear component bilaterally, with left greater than right and a clinically presumptive secondary endolymphatic hydrops (SEH) on the left. Systematic desensitization is also used to combat the attentionrelated component of an individual's perceptive response to tinnitus. The incomplete group was made up of 15 patients who returned their device or chose not to complete the course of treatment during the study period. All patients were counseled regarding the nature and course of tinnitus as a complex symptom and their candidacy for the Neuromonics device.
Across all patients, the mean percent improvement declines slightly with each increment in duration, although this did not achieve statistical significance.
Our data were somewhat limited, as the number of patients who successfully completed the protocol with initial TRQ scores at either extreme was small. For the future, it is hypothesized, a particular clinical type of a predominantly central tinnitus, now considered to be a symptom, will be identified to be a specific disease entity. Reciprocal innervation from the thalamus to the medial temporal lobe system (MTLS), including the amygdala (AG), hippocampus (HP), paparahippocampal formation (PH), entorhinal cortex (EC), perirhinal cortex (PC), ACG, and hypothalamus (HYP), comprise an endogenous system of the CNS as hypothesized for sensory processing [53,54]. The main clinical manifestation of tinnitus is that of multifactorial characteristics; therefore, single drugs may have multiple sites of action. Recording LDF was performed at the second or third tri al to decrease effects of stress (for example: etectrlcal stimulation and insertion of electrode through the ear drum) on the autonomic nervous system.
However, no previous report about ES showed the relationships between tinnitus suppression and increased parasympathetic nerve tone. Significant side-to-side count differences were determined by standard statistical analysis. Vestibular testing revealed a vertical upbeat nystagmus in all position tests with normal caloric testing. Across all 47 patients, 48.9% achieved a successful reduction of 40% or greater in TRQ score. Although only the completed group had final TRQ scores, some patients in the other groups had one or more follow-up tests. Further clinical information will be needed to determine whether patients with extremely high initial TRQ scores, and thus more bothersome tinnitus, are perhaps more likely to benefit from treatment. For tinnitus, the endogenous system is hypothesized to result in the establishment of a "paradoxical memory" for the aberrant auditory sensory stimulus (tinnitus) and has a reciprocal interaction with the thalamus [16]. We recommend a combination drug strategy to increase the efficacy of attempts at tinnitus relief.
Blood flow started to increase with a stimulation intensity of 50 μA and continued to increase gradually as the intensity of stimulation increased. Patients with the sharply sloping pattern showed a greater increase in CBFR compared with patients with the slightly sloping pattern.
There was no correlation among pure-tone average, initial TRQ score or duration of use, and percentage change in TRQ score for those with at least one follow-up test. The associated brain function processes within the neuroanatomical substrates of the sensory component include memory, stress, masking, fear, reward, and autonomic functions. For the affect component, particular attention is directed with pharmacotherapy to avoid drug tolerance and or habituation.
Response to treatment is monitored by telephone communication and follow-up office visits as determined by the clinical course of the SIT 1,37. The Tatio of CDBF at the cessation of stimulation to that at the initiation of stimulation (CBFR) was calculated. If you seek medical help for tinnitus, your treatment may include: sound therapy, acupuncture, hearing aids, cochlear implants, electrical brain stimulation, mindfulness training, and neck exercises. Based on these preliminary findings, treatment with the Neuromonics device is successful in reducing TRQ scores in appropriately selected patients with tinnitus. Stress is considered to be a modulator of the clinical course of the tinnitus with the accompanying reduction and alteration in auditory masking [2,230-232]. The value of cutaneous digital blood flow (CDBF) at the initiation of stimulation was defined as the mean value between the maximum and minimum of the blood flow at the point of the initiation on the recording paper.
The number of patients with other types of audiogram patterns was too small to permit comparison of treatment efficacy. Algorithm 2, Affect (Emotional-Behavioral) Component: The neuroanatomical substrates of the affect (emotional) component are highlighted by the OFC, PFC of the frontal lobe, PAC, MTLS of the temporal lobe, and insula. Mean CBFR in patients with highpitched (3000 to 8000Hz) pre-stimulation tinnitus (n=16) did not differ significantly (p>0.6) from that of patients whose pre-stimulation tinnitus was classified as a noise (white and band noise, n=13). Reciprocal innervation is hypothesized to occur between the PAC of the sensory component and the OFC, ACG, PFC, MTLS, and insula.
There was no significant difference (p>0.4) in mean CBRF between patients with high-pitched tinnitus and patients with low-pitched tinnitus.
For example, if impacted wax is the culprit, it is easily removed or, if a medication is causing the tinnitus, you would need to discontinue the medication or ask your health care provider to prescribe an alternative drug. Ginkgo-Biloba, betahistine (Serc) , Zinc, and acupuncture are sometimes advocated as treatment for intractable tinnitus. The insula, by its central location, is hypothesized to exert a modulating effect among the sensory, affect, and psychomotor components. The medical name for this sometimes-tormenting condition is tinnitus, and medical researchers have made substantial headway toward discovering why it happens. The thalamic activity is ongoing with reciprocal projections to the PFC, OFC, and parietal lobe. Hufford serves on the editorial boards of several journals, including Alternative Therapies in Health & Medicine and Explore.
Algorithm 3, Psychomotor Component: The neuroanatomical substrates of the psychomotor component include the insula, parietal lobe, striatum, and cerebellum. In Traditional Chinese Medicine, tinnitus is believed to result from a disturbance in the flow of energy, or chi, to the liver or kidney. Alternative, Natural and Chinese Medicine Treatment Options for Tinnitus – Acupuncture Points, Acupressure, Herbal Formulas for Tinnitus. The thalamic activity is ongoing with reciprocal innervation of the parietal lobe, OFC, and PFC. Studies indicate that CBT is most effective as a treatment for tinnitus when it is combined. Significant for the sensory-affect transformation is considered to be the interaction between the striatum, parietal lobe, and OFC via the insula.
