Chronic tinnitus can be caused by a variety of things, from impacted ear wax to medications that damage nerves in the ear, middle ear infection, and even aging. When chronic tinnitus is caused by a definable problem, like ear wax or grinding your teeth at night or taking aspirin, addressing that problem will often turn down the volume. Not all insurance companies cover tinnitus treatments in the same way, so be sure to check your coverage. Hair cells in the cochlea transform sound waves into electrical signals that travel to the brain’s auditory cortex.
I am proud to be a part of the American Resident Project an initiative that promotes the writing of medical students residents and new physicians as they explore ideas for transforming American health care delivery. I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Tinnitus is the perception of sound within the human ear in the absence of corresponding external sound.
Tinnitus is not itself a disease but a symptom resulting from a range of underlying causes.
Featured TestimonialI have struggled with hearing loss for many years, and bought hearing aids elsewhere before I went to HearFlorida. In the October issue of Trends in Cognitive Sciences, researchers say identifying the problem is the first step to developing effective therapies for these disorders, which afflict millions of people.
The scientists describe how the neural mechanisms that normally "gate" or control noise and pain signals can become dysfunctional, leading to a chronic perception of these sensations.
In both disorders, the brain has been reorganized in response to an injury in its sensory apparatus, says Josef Rauschecker, PhD, DSc, director of the Laboratory for Integrative Neuroscience and Cognition at GUMC. Areas of the brain responsible for these errant sensations are the nucleus accumbens, the reward and learning center, and several areas that serve "executive" or administrative roles --the ventromedial prefrontal cortex (VNPFC) and the anterior cingulate cortex. All of these areas are also important for evaluating and modulating emotional experiences, Rauschecker says. Ironically, the brain plasticity that produces some of these changes provides hope that this gatekeeping role can be restored, Rauschecker says.
Rauschecker, an expert in tinnitus, collaborated with Ploner, who studies chronic pain, during his senior fellowship at the Institute of Advanced Study at TUM. The National Institutes of Health (RC1-DC010720), the American Tinnitus Association, the Skirball Foundation, the Tinnitus Research Initiative and the Tinnitus Research Consortium have supported tinnitus research in the Rauschecker lab.

It is necessary to limit or to stop completely some habits if you want to get rid of ear noise ( howtogetridoftinnitus.org ).
Sound therapy is used as a way to mask or distract from the annoying noises associated with buzzing in ears ( cure tinnitus ).

INTRODUCTION: Comorbidity of chronic tinnitus and mental disorders may result in more disability. OBJECTIVES: This research provides an evaluation about the effects of medically treated comorbid mental disorder on chronic tinnitus. MATERIALS AND METHODS: Fifty-five patients diagnosed with chronic tinnitus and mental disorders were randomly requited by producing a before-after design. RESULTS: Three months medical treatment puts forward the argument that among mental disorders, anxiety and major depressive disorder demonstrate a significant reduction.
CONCLUSION: Findings lay emphasis on tinnitus severity reduction and connection might be established between alleviated mental disorders comorbidity and the improvement of quality of life.
The word tinnitus originates from the Latin word "tinnier" which means tinkling or ringing1. The aim of this study is to determine the impact of treatment of Comorbid mental disorders accompanied chronic tinnitus on the outcomes of the tinnitus symptom. This study was conducted by creating a before-after design in two discrete phases during August 2009 and 2010. The Structured Clinical Interview for DSM-III-R, axis I psychiatric disorders (SCID).The Structured Interview for DSM-III-R (SCID-I) was applied as a diagnostic instrument for DSM-III-R axis I psychiatric disorders to identify mental disorders. The P-THI measures the impact of measures and tinnitus on daily life, which had been developed by Newman et al.
The SCL-90-R is a 90-item self-report system inventory developed by Derogatis in the 1980s26. Pitch and Loudness Match tinnitus (PMT and LMT) was evaluated in tinnitus subjects using an external tone presented to the contra lateral ear. This study has been approved by the Ethical Committee of ENT and Head & Neck Research Center, Iran University of Medical Sciences (IUMS) code number of MT-4250.
The prevalence of mental disorders yielded from SCID among the study subjects is shown in Table 3. The consequences of comparing the mean scores of severity of tinnitus (LMT) and the disability (THI),which were brought about before and after pharmacotherapyof mental disorders, revealed significant reduction (Table 5). By employing Pearson correlation coefficient analysis provided information made it manifest that disability resulted from tinnitus (THI) has the positive and significant correlation solely and merely with depression diagnosis variable. This study shows that three months of medical treatment for comorbid mental disorders with chronic tinnitus reduces the intensity and disabilities of tinnitus. While yet, theory that maintains the concept in which chronic tinnitus is considered to be a type of chronic stress having the potential to develop essential changes via neuronal network, was underpinned by other evidences. Regardless of the mechanism of psychotropic agents on buzz sound of tinnitus, the study results confirmed that these agents could be effective on the intensity of tinnitus, reducing the resulted disabilities and improving the quality of life.
This study was registered and supported by the ENT and Head & Neck Research Center, Iran University of Medical Sciences (IUMS) with collaboration of Tehran Psychiatric Institute, Mental Health Research Centre. Paper submitted to the ITJ-SGP (Publishing Management System) on July 31, 2013; and accepted on August 31, 2013. Tinnitus is a commonly described as a consistent humming or ringing sound in the ears that can be a symptom of almost any known hearing problem.
Avoiding the dentist because your tinnitus is aggravated by the sounds of their tools will only cause you more problems.
Although tinnitus is not usually a serious condition, it can seriously impact your life when it doesn’t stop or when the noise level becomes overwhelming.

Please note that any and all information contained on this website is purely for informational purposes only and should not be interpreted as medical advice. It’s common after sitting through a loud concert or an exuberant football game, or after taking aspirin or an antibiotic for a while. Damage to hair cells in the ear’s cochlea (see the illustration below) are suspected as a common pathway for these causes. You can do this by listening to music or having a radio, fan, or white-noise machine going in the background.
If you’re willing to enroll in a research study, you may be able to receive a cutting-edge treatment free.
When these cells are damaged by loud noise, medications, or other problematic inputs, brain circuits don’t receive the signals they are expecting to get. At the time I found it to be a cynical yet eerily accurate portrayal of the underbelly of academic medicine. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. Causes include ear infections, foreign objects or wax in the ear, nose allergies that prevent (or induce) fluid drain and cause wax build-up, and injury from loud noises. But now the Neuromonics Tinnitus Treatment lets you relieve these symptoms and reclaim your life. I instantly felt comfortable with the staff and audiologist, received more thorough testing than I ever had, am hearing better than I have in years and therefore participating in activities and conversations more. They traced the flow of these signals through the brain and showed where "circuit breakers" should be working -- but aren't. Tinnitus can occur after the ears are damaged by loud noise, but even after the brain reorganizes itself, it continues to "hear" a constant hum or drum.
Because these systems rely on transmission of dopamine and serotonin between neurons, drugs that modulate dopamine may help restore sensory gating, he says. The good news about TMJ-causing ringing in ears is that if you treat the TMJ you will also heal the ear noise. A great way to get rid of buzzing in the ears and alleviate blockage is to drain the fluid that has gathered in the tube.
A 50-year old male patient with tinnitus participated in three SCP training blocks, separated with 1-month breaks. They underwent three months of drug therapy for comorbid mental disorders by psychiatrists. Pearson Correlation coefficient ostensibly reveals that there is no significant relationship between mental disorders and tinnitus severity. This study was performed in the ENT and Head & Neck Research Center, Hazrate Rasoul Medical Complex, Iran University of Medical Sciences, Tehran, Iran. In the first phase in order to investigate the prevalence of mental disorder in tinnitus, amongst 2350 patients suffering from tinnitus registered at the ENT and Head & Neck Research Center of Hazrate Rasule General Hospital, 400 patients over 18 years old, were clinically interviewed by well-trained psychiatrists22. The global severity index (GSI), is one of the three global indexes which measures the extent or depth of the individual's psychiatric disturbances.
This task was accomplished using a Tinnitus Evaluation Device (TinnED®) which includes 6 channels to reconstruct the Most Troublesome Tinnitus (MTT) with a similar frequency and intensity.
The results of comparing the mean scores of the psychological indexes yielded before and after treatment; show that the pharmacotherapy has been significantly successful in reducing the severity of the psychological symptoms. The results revealed that medical treatment of comorbid mental disorders was successful in improving the subscales of sleep, emotional distress, cognitive distress, intrusiveness and auditory perceptual difficulties (Table 4). Is this due to the direct effect of psychotropic drugs on tinnitus or the result of reduction in the disabilities and the subjective perception of tinnitus? Shulman's study has shown that treatment with GABAergic and benzodiazepine medication results in local blood flow increase in SPECT series which is accompanied by a decrease in the intensity of tinnitus19.
Prescribing antiepileptic drugs might reduce the intensity of tinnitus32.Tinnitus can be directly affected by antidepressants and mood stabilizers33. Therefore, diagnosing comorbid mental disorders and managing them correctly can alleviate the subjective perception of annoying and continuous sound in the ear and have positive effects on the outcome of chronic tinnitus and improve the quality of life.
In a study performed by Zoger, the results demonstrated that depression and anxiety were not directly correlated with the intensity of tinnitus, but it was efficacious in diminishing the features of tinnitus disabilities43.

For instance, TMJ and hypertension, are both medical conditions that can cause tinnitus, and if they are not treated, your tinnitus will not get any better.
The external sound can work to drown out the noise you hear in your ears, providing some temporary relief. No matter how much your friends and family try to be supportive, there is nothing to compare with someone who really understands what living with tinnitus is like because they have it, too. The interaction between supplement and prescription can actually bring on the symptoms of tinnitus, so give your doctor a list of any vitamins, herbs, or homeopathics you’re taking.
Many believe that dental problems actually lead tinnitus to become severely and incurably worse, so taking care of your teeth by visiting the dentist is enormously important if you are diagnosed with tinnitus. If you are really having fun, you will not think about tinnitus anymore and you will not notice it as much when it occurs. Try to figure out what the sounds are, from bubbles coming up your esophagus to blood rushing through the vessels in your ear. You should seek a doctor’s advice if its long-term, or if it is affecting your concentration. But as many as 50 million Americans have chronic tinnitus (pronounced tih-NITE-us or TIN-ih-tus)—a constant ringing, whistling, buzzing, chirping, hissing, humming, roaring, or even shrieking.


As I write in the September issue of the Harvard Women’s Health Watch, chronic tinnitus can also be a symptom of Meniere’s disease, a disorder of the balance mechanism in the inner ear. If money is no issue, you can buy devices worn like hearing aids that generate low-level white noise.
They respond by generating abnormal activity, which results in the illusion of sound, which is tinnitus.
Most feel helpless about improving their work conditions or solving technical problems in patient care. Tinnitus is also a side-effect of some oral medications, such as aspirin, and may also result from an abnormally low level of serotonin activity.
I am so impressed by the knowledge, care, and willingness to help, and cannot be more thankful for this improvement in my life. Chronic pain can occur from an injury that often is healed on the outside but persists inside the brain. Noise related hearing loss or ringing in ears can be caused from using music headphones at a loud level for a long period of time.
Since 1962 it has been known that same nerve feeds all of the muscles of your jaw as well as two important ear muscles. Ideally a practitioner of naturopathy can perform this but you can also complete it by yourself. After the training the patient reported decreased tinnitus loudness and pitch, as well as improved quality of daily life. Tinnitus often co-occurs with a hearing impairment, hyperacusis, problems with concentration, nervous strain, sleep disorders, headache, excessive stress, anxiety disorders and depression (CrA¶nlein et al. At first tinnitus was transient but over time it turned into a chronic sensation of a high-frequency squeak. Values below the arrows on the right side represent the mean amplitude of SCPs generated in a single trial. He stated, however, that the pitch of tinnitus decreased and the sensation became less intensive. Study instruments are Tinnitus Handicap Inventory, Tinnitus Questionnaire, Loudness Match Tinnitus, Hamilton Depression Rating Scale, Beck Anxiety Inventory, The Structured Clinical Interview and Symptom Check List -90. The statistics lend support to profound effect of major depressive disorder as a key factor on tinnitus disability exacerbation. Tinnitus is a common complaint, usually subjective, perceived only by the patient; thus, diagnosis and monitoring rely basically on self-report3.
In the second phase from among aforementioned 400 patients, the ones suffering from comorbid mental disorder on tinnitus were selected.
The subjects with chronic severe tinnitus having scores more than 44% in TQ-P were enrolled in the study. The accuracy of the calibrating equipment should be sufficient to determine whether the TinnED® is within the tolerances permitted by American Standard Specification for Audiometers, S3.6-2004. Items with quantifiable severity were ranked on a scale of 0-4 and those measuring symptoms that weredifficult to assess reliably were ranked on a scale of 0-229. In the case of absence or any other reasons, the next registry would be contacted by telephone and invited to participate in the study.
Each of the study subjects was visited at the time of zero, two and four weeks later, then eight and twelve weeks later from the time of zero. We applied Kolmogorov Smirnov as a method for testing the normality of distribution ofcontinuous variables, which demonstrated that all the numeric variables had normal distributions (P > 0.05).
Comparing the outcomes of treatment on mental disorder diagnosis in each study subjects, revealed that pharmacotherapy was effective on anxiety disorders and depressive disorder but there have not been significant changes in somatoform, eating and bipolar disorders (Table 3).
But the comorbid mental disorder on tinnitus doesn't have a significant and meaningful effect on tinnitus severity (LMT) (Table 6).
Furthermore in stress process, dopaminergic system placed in prefrontal region, medial temporal lobe and the hippocampus is strongly influenced34,35.

Your doctor my offer you a trial of the hearing aid before you have to make a purchase, as they can be quite expensive. When you join a support group, you will find you can share tips and ideas with others who are living through the same experiences you are. You should not dismiss tinnitus as an insignificant issue, the constant discomfort could have a heavy toll. If you go to bars where people smoke, or in cramped quarters where people smoke try to avoid them. Luckily, most cases are temporary and can be easily alleviated with the help of tips like the ones found in this article. It is important that you limit or avoid exposure to the noises you suspect are causing your ear noise. Over activity of your jaw can make your ear canal sensitive and cause ringing in your ears.
There are noise machines that can make ambient sounds like ocean waves or twittering birds. A quantitative electroencephalography analysis revealed close to normal changes of resting state bioelectrical activity in cortical areas considered to be involved in tinnitus generation.
On several days the patient was not able to participate or the registered EEG signal was contaminated with artifacts and could not be used for the estimation of mean absolute SCP amplitudes. Medical treatment also touches on issue such as tinnitus severity, its disabling effects and TQ subscales that statistics shows significant trends in their reduction.
Tinnitus of the same level may be regarded as a problem by a subject while it may be even unrecognizable for another subject4.
Improvement or worsening of condition was determined by patients' declaring a change in tinnitus of at least 40%. After obtaining a fully informed consent from each study subject, and having evaluated and completed the study instruments, they were entered into study. Paired sample t-test, and McNemar test were conducted to compare variables before and after intervention. Chronic stress via a complex neurotransmitter network can result in endocrine and autonomic hyperactivity.

The present case study indicates that SCP Neurofeedback training can be considered a promising method for tinnitus treatment.
In training block 3 the difference between positive and negative trial SCP amplitudes was pronounced and maintained until the end of block 3.
On the remaining days, the registered EEG signal was contaminated with artifacts or the patient was unable to perform the training. In addition, his sleep quality improved and it was easier to fall asleep and get up more rested. The prevalence of tinnitus varies from 3% to 30% depending on the definition of tinnitus and the study group3. The main goal of this study is the medical therapy of psychiatric disorders but not tinnitus. All of the subjects remained in the study and followed their medical prescriptions for three months.
There is a direct pathway between the limbic system and the prefrontal area via dopamine neurotransmitter. Psychological aspect of subjective tinnitus has been emphasized to assess tinnitus and its disabilities.
If you decide to make a purchase, make sure you can contact a person (not a machine) at the company and that there is a refund policy in place. Place your chin against the palm of your hand and while using pressure open and close your mouth repeatedly to help reintroduce flexibility. As already stated, cortical excitation thresholds have been found decreased in tinnitus patients (Kropp et al. From day 7 the difference consistently increased until the end of training block 1 and on day 10 the mean SCP amplitude in positive trials reached a positive value (Table 1).
Bottom plots show mean SCP amplitude values obtained in b negative and c positive SCP feedback trials in all training blocks. Among positive trials the mean SCP amplitude reached positivity on day 9 of block 1 and on day 4 and day 8 of block 3.
The interview revealed that the most important benefit for the patient was that he felt in control of the tinnitus sensation and was able to reduce it by 20a€“30 %. Patients who experience tinnitus often report significant accompanied morbidities such as sleep deprivation, lifestyle detriment, emotional disturbances, work difficulties, social interaction problems, and decreased overall health5-7.
Subsequently, with the auditory threshold level at that frequency, the sound was increased in 1-dB steps until a patient reported that the external tone equaled the loudness of the tinnitus. This pathway shows that chronic stress such as chronic tinnitus can have a crucial effect on affective disorders; however, this can also be seen in other chronic physical disorders such as asthma, pain and atypical dermatitis36 and may not be specific to chronic tinnitus. It is important that you pay attention to how your noise in the ears reacts to alcohol and shun it if it worsens your symptoms. You can also free up your jaw and relieve tension by making your tongue touch the top of your mouth and then gently opening and closing your jaw. Near where your tongue meets the tonsillar pillar and under the flesh you should be able to feel your Eustachian tube. Several people with tinnitus recommend finding a radio station of just static to find relief from ear noise. Historically, it had been thought as originating from the ear itself (see review in: MA?ller 2011). Audiological assessment [pure tone audiometry, impedance audiometry, auditory brainstem responses (ABR)], together with MR and CT exams revealed normal hearing and lack of any organic aetiology of tinnitus.
In block 2 the difference remained stable towards day 5, on day 6 and 7 it almost vanished, and again increased at the end of training block 2 (day 8). Trend lines represent the direction of SCP amplitude changes in the course of training days.
Bottom plots show mean SCP amplitude values obtained in negative (b) and positive (c) transfer trials on certain days in all training blocks.
Although causative relations are yet unrevealed, patients with tinnitus are at increasing risk for depression, anxiety and insomnia5,8,9. None of the study subjects had taken any medication for their tinnitus including psychotropic or antiepileptic agents since a long period before being included in the study. The subjects had to have LMT over 6 decibel sensation level (dB SL) to be included in this study. Some gentle massage exercises like stretching your jaw muscles are beneficial for releasing jaw tension.
Gently stroke the Eustachian tube from the ear side of the back of the throat towards the middle several times.


Devices that you can wear in your ear that make low-level white noise can help suppress buzzing in the ears symptoms. However, in 1987 JA?rgen Tonndorf pointed to similarities between tinnitus and phantom pain perception and proposed a neurophysiological model of tinnitus generation in the central nervous system (CNS). It is indicated that 48% to 60% of patients suffering chronic and disabling tinnitus have major depressive disorder (MDD)10-12. The least objective score was ± 2 dB sensation level (SL) which is considered important clinically28. Any problems you may have with gritting your teeth while asleep will aggravate problems with ringing in ears and TMJ.
Do this daily and consistently for up to a week to help relieve effects of ringing in ears. Finding noise machines is as easy as turning on your radio or going to your drugstore to find ear devices. Since then many new theories have been developed to explain the aetiology of tinnitus (De Ridder 2011; Schlee et al.
From day 3 of training block 3 the difference between mean SCP amplitudes in negative and positive trials was stable until the end of the block, with positive trials reaching positive mean SCP values on days 4 and 8 (Table 1).
Ultimately, the patient became more relaxed, which in turn improved his contacts with family and friends.The Tinnitus Functional Index (TFI)Before the training the patienta€™s overall score in TFI was 45 points, whereas after the intervention it decreased to 6 points.
Asplund reported poor sleep and frequent waking to be more common among chronic tinnitus patients than the general population in both sexes13. See your dentist to get fitted for a mouth guard if you suffer from jaw clenching or teeth grinding. Many clinical trials have been performed in order to evaluate the efficacy of psychotropic agents on tinnitus so far. Most have converged with the Tonndorf model and showed that tinnitus probably occurs due to an abnormal neuronal activity caused by auditory deprivation (Jastreboff 1990, 1995).
The fixed-order training schedule was applied to facilitate differentiation between the two types of trials. The results obtained in the 8 subscales of the TFI in the pre- and post-training situations and the percentage change are depicted in Table 3. Clonazepam and antidepressants such as nortriptyline and amitriptyline have been proved to be effective in reducing the severity of the problem and improving the quality of life of tinnitus patients14-18. The concept that has gained the most attention implies a thalamocortical dysrhythmia in tinnitus (De Ridder et al. As indicated by Strehl (2009), maintaining one specific brain state for a long duration is a considerable challenge. The studies have illustrated that Benzodiazepines and GABA-egric agents may decrease the severity of tinnitus and the SPECT evaluation has proved that the brain blood flow increases objectively in tinnitus19.
The fixed order of trials, furthermore, enhances the flexibility of self-regulation mechanisms of cortical excitability, which is desired in patients with tinnitus. Using SSRIs has been successful in reducing the severity of tinnitus by lowering the conduction of impulse of tinnitus20,21. However, the patient did not accept this form of therapy, as he was afraid of the possible side effects. According to the authorsa€™ clinical experience, a predictable and an explicit training structure, as opposed to one randomly distributed, accelerates the process of acquisition of SCP self-regulation. The learning process advances more quickly when basic capacities are acquired first, followed by those of higher complexity (Gagne 1970; Sweller 1976). In normal conditions sounds increase thalamocortical rhythms to gamma band activity (Joliot et al. Moreover, the predictable arrangement of the training could help reduce frustration related to uncertainty. This is particularly important in patients with tinnitus who often demonstrate high levels of anxiety and emotional reactivity (Landgrebe and Langguth 2011a; CrA¶nlein et al.
As a consequence lateral inhibition is reduced, inducing gamma band activity in brain regions adjacent to those deprived of auditory input.
The structure of the tests and the patienta€™s outcomes have been described below.Standard and High-Frequency Pure Tone AudiometryA standard and a high-frequency pure tone audiometry (PTA and HFA, respectively) were performed by an expert audiologist in a sound-proof chamber according to ISO 8253-1 (1989) standards and recommendations by the British Society of Audiology (2011). Whenever the mean SCP amplitude exceeded the threshold fixed at the level that predicted 30 % successful trials (see above), the sun animation rotated, the diode turned on and the applause sound was produced. All measurements were performed with the use of a Madsen Astera audiometer (GN Otometrics, Germany) and Sennheiser HDA-200 headphones (Sennheiser Electronic GmbH & Co.
In each training block (1a€“3), transfer trials constituted the third run and were arranged in a fixed order. 1999, 2005).The complex nature and the yet unexplored aetiology of tinnitus make the diagnostic assessment difficult.
Although clinical practice offers a number of various treatment methods for tinnitus, no one is entirely effective. They have also been hypothesized to be more ecologically valid, as compared to regular feedback trials (Zuberer et al.
Both tests were performed according to a modified ascending Hughsona€“Westlake procedure (Carhart and Jerger 1959). In most instances, however, tinnitus is idiopathic and only non-pharmacological treatment methods can be recommended (e.g. The test started with a presentation of a tone at one of the tested frequencies and at a clearly audible (but not loud) sound level (e.g.
He was asked to sit in front of a PC and use a printed Visual Display of the training procedure, imaging an actual training session at the Institute. It has been suggested that despite no immediate feedback, home practice not only improves the skills trained in the clinical setting but also facilitate the transfer of self-regulation capacities to everyday life (Strehl 2009).EEG Signal RecordingThe EEG signal used for Neurofeedback was registered from the active electrode placed at the vertex (Cz position) (Jasper 1958).
Reference electrodes were located on linked mastoids and the ground electrode was placed on the back of the neck (C7 position). During the training, electro-oculogram (EOG) was recorded from two additional electrodes attached above and below the right eye The EOG signal was used by the instructor and by the patient himself to monitor and reduce the effect of eye movements on the amplitude of the produced SCPs. The HFA measurements demonstrated age normal hearing thresholds for all tested high frequencies in both ears, lower or equal to 50 dB HL (Rodriquez Valiente et al.
The patient was also asked to refrain from eye movements during positive and negative SCP trials and try to blink only during 2-min breaks between them. 2014).Tinnitus Handicap InventoryAn experimental Polish version of the Tinnitus Handicap Inventory was completed by the patient before the training. This test is used for self-evaluation of the influence of tinnitus on three tiers of daily functioning, involving functional, emotional and catastrophic reactions. This trial was considered failed due to the eye movement-related artefacts, even if the required SCP amplitude threshold was obtained, and the patient did not receive the reward (the audio-visual stimulus was not presented).
The EEG signal recorded in each training session was carefully inspected offline and grand average SCP was calculated based only on artefact-free trials. It has been shown that the power of delta and alpha frequency bands is abnormally changed in patients with tinnitus (with alpha decreased and delta increased), as measured in the right temporal lobe and the left frontal lobe.
A correlation between the power of alpha and delta, the frequency index of both bands and the tinnitus-related distress (evaluated with the Tinnitus Questionnaire) has also been found in tinnitus patients (Weisz et al.
Five grades of tinnitus handicap are distinguished by calculating the total score: Grade 1 (0a€“16 points)a€”slight or no handicap, Grade 2 (18a€“36 points)a€”mild handicap, Grade 3 (38a€“56 points)a€”moderate handicap, Grade 4 (58a€“76 points)a€”severe handicap, Grade 5 (78a€“100 points)a€”catastrophic handicap. The outcomes of SCP Neurofeedback training were evaluated with the use of: (a) a detailed clinical interview, (b) the Tinnitus Functional Index (Meikle et al.
A simultaneous delta-down and alpha up-training could therefore significantly reduce loudness of tinnitus and normalize brain activity underlying tinnitus generation (Dohrmann et al.
2012), (c) measurement of tinnitus characteristics (type, pitch and loudness) with an in-house software programme Tinnitus, and (d) QEEG. 2007).A special type of the Neurofeedback training, using slow cortical potentials (SCP Neurofeedback), has been successfully employed in the treatment of different brain dysfunctions, such as epilepsy, ADHD and migraines (Kotchoubey et al. All these tests were performed before and immediately after SCP Neurofeedback training.Tinnitus Functional Index (TFI)An experimental Polish version of the Tinnitus Functional Index was completed by the patient to monitor how his subjective perception of tinnitus changed after the training (Meikle et al. TFI is a self-report instrument measuring the severity of tinnitus and responsiveness to treatment.
TFI is divided into 8 subscales, corresponding to 8 main domains of daily life that might be affected by tinnitus: INTRUSIVE, SENSE OF CONTROL, COGNITIVE, SLEEP, AUDITORY, RELAXATION, QUALITY OF LIFE, EMOTIONAL. Slow cortical potentials are direct-current shifts of the EEG signal, generated in the upper cortical layer.
Responses are given on a 1a€“10 point scale, reflecting the subjectively perceived effect of tinnitus within the previous week.
SCPs are considered event-related potentials, as they are not oscillatory in nature but induced by external or internal events. The Beck Depression Inventory has 21 items which describe feelings of pessimism, guilt, failure, irritation, insomnia, weight loss, etc.
Scores are calculated separately for each subscale and for the whole questionnaire (an overall TFI). The overall score of a‰¤19 points is considered to indicate no or mild, 20a€“28 pointsa€”moderate, and a‰?29a€”severe depressive symptoms.
This calculation produces a score in the range of 0a€“100 points and provides a straightforward and an accurate measure.
A series of experiments performed in the 80s and 90s by a scientific team led by Niels Birbaumer and Thomas Elbert indicate that SCPs are related to cortical responsiveness (Birbaumer 1999; Birbaumer et al.
The suggested severity grading for the overall and subscale mean scores is as follows (Henry et al. Accordingly, negative SCPs are associated with the depolarization of large cortical cell assemblies and the reduction of their excitation thresholds.
Their occurrence is believed to be a manifestation of an a€?activation statea€? and preparation of particular brain regions to perform a task.
Positive SCPs are believed to correspond to decreased cortical excitability and an increased excitation threshold of neuronal populations. 2006a, b).According to the authorsa€™ best knowledge, there have not been any studies published to date applying SCP Neurofeedback training in tinnitus patients. This paper presents a single case study of a patient who participated in a series of specifically designed training sessions during which he practiced the self-regulation of SCPs. As previously described, tinnitus can be related to abnormal neuronal synchronization, typically at high frequency ranges, in various cortical regions (see e.g. There were 3 feedback and 1 transfer (with no feedback provided) runs performed in each session (see next paragraphs for a more detailed description). Following the patienta€™s suggestions, the stimulation was delivered to both ears, starting with pure tones of a very high frequency (20 kHz). Furthermore, some studies suggest a significantly decreased excitation threshold of cortical neurons in patients, as compared to healthy individuals (Kropp et al. Then, the selected tone was intensity-modulated to choose the best match (80 dB HL was the starting point). The procedure was continued until the patient defined the pitch-loudness combination that was most alike the experienced tinnitus. No information was provided to the patient about the parameters of tinnitus, in order to exclude any subjective factors that might have affected the experimental procedure.QEEG Data Acquisition and AnalysisThe key tool to assess the outcomes of SCP Neurofeedback training was quantitative electroencephalography (QEEG). In the current work we hypothesize that acquiring the ability to regulate cortical excitability would elevate the abnormally low neuronal excitation thresholds and restore cortical excitation-inhibition homeostasis. This normalization should, in turn, attenuate the undesired neuronal synchronization underlying tinnitus and decrease or completely cancel out the tinnitus sensation.
Therefore, the aim of the present study was to verify whether SCP Neurofeedback training protocol could be used to suppress tinnitus sound and alleviate tinnitus-related symptoms. In the first block the patient kept his eyes open and fixated on a point of his choice in the room. The electrodes were distributed on the head of the patient according to the International 10a€“20 system (Jasper 1958). The signal was referenced to linked mastoids and the ground electrode was placed in the FCz position. In the first session of block 1 the SCP amplitude threshold, which the patient had to exceed to be rewarded, was fixed to ensure the level of 30 % successful trials in each run. As it was indicated by Kleinnijenhuis (2007), this success level is sufficient to achieve optimal SCP self-regulation learning outcomes. In subsequent sessions the thresholds were continuously updated, using mean SCP values obtained in all positive or negative SCP trials completed on the previous day, so that probability of success remained at approximately 30 %.
After-recording eye movements and muscle artefacts were removed with the independent component analysis (ICA) method and visual inspection (Congedo et al. The mean absolute amplitudes of the specific bands were then used to determine their distribution on the head.
