Chronic subjective dizziness (CSD) is a common vestibular disorder characterized by persistent non-vertiginous dizziness, unsteadiness, and heightened sensitivity to motion stimuli that may last for months to years after events that cause acute vestibular symptoms or disrupt balance. Recent research has also begun to reveal the psychological factors that predispose and perpetuate CSD (Staab and Ruckenstein, 2003, 2005).
Visual cortical areas are also critical for spatial orientation and could consequently play a key pathogenic role in CSD. The present study was aimed at elucidating whether the brain regions that process vestibular, visual, and anxiety-related information show anomalous activity or altered connectivity patterns in response to vestibular stimulation in CSD patients relative to controls. CSD patients with previous vestibular neuritis also underwent caloric test in the acute stage of their peripheral vestibular disease and 6 months later.
In a first analysis, 18 CSD patients were compared to 18 healthy volunteers who were matched for demographic variables, personality traits, and anxiety and depression measures (see Table 1). It was also unlikely that the vestibular stimulation related to the MRI scanner itself (Roberts et al., 2011) could influence our results, as this form of spurious vestibular stimulation is known to activate the canals rather than otolith receptors.

The bithermal caloric test, cervical VEMP and ocular VEMP examinations assess the function of different vestibular end organs and at times even different central pathways.
This journal club will focus on how different types of self-report measures including the Hospital Anxiety and Depression Scale (HADS), the Dizziness Handicap Inventory (DHI) the Structured Interview for Migrainous Vertigo (SIM-V), and a case history questionnaire can be helpful in the assessment of patients presenting with vertigo, dizziness and unsteadiness. This journal club will focus on a description of what processes are believed to occur in central compensation following predominantly profound unilateral vestibular system impairment.

It is characterized by a sensation of non-vertiginous dizziness and unsteadiness that is typically present throughout the day on most days for at least 3 months (Staab, 2012). The anxiety-related personality traits of neuroticism and introversion were significantly associated with CSD but not with other disorders that caused similar levels of chronic vestibular symptoms (Staab et al., 2014). Eighteen healthy volunteers were included in the control group, while 10 were included in the PIVC localizer group (see below). To measure personality traits of the five Factor Model (neuroticism, extraversion, openness, agreeableness, conscientiousness), they completed a computerized version of the Italian translation of the Revised NEO Personality Inventory (NEO-PI-R) (Costa and McCrae, 1997). Exclusion criteria included active neuro-otologic disorders other than CSD, chronic medical illnesses, pregnancy, medication use, smoking, and history of head injury.


In a follow-up analysis, we also excluded 7 CSD patients and 1 control participant who showed active psychiatric comorbidities when assessed with the MINI (Tables 2, 3). List of the active psychiatric conditions in the group of patients with chronic subjective dizziness (CSD) and healthy controls. Demographic and clinical characteristics in patients with CSD and healthy controls after removing the 7 CSD patients and 1 control that showed the presence of the active psychiatric comorbidities listed in Table 2. Forty-five stimuli per each type were grouped in blocks lasting 15 s each (rest blocks also lasted 15 s).

Also incorporated into this lecture will be illustrative patient data and current beliefs about how the ocular motor system contributes to the process of compensation in unilateral and bilateral peripheral vestibular system impairment.
In line with this view, we have recently found that the functional interplay between visual and vestibular regions was altered in favor of higher visual cortical activity in people with high levels of neuroticism when exposed to sound-evoked vestibular stimuli (Indovina et al., 2014). We hypothesized that, relative to controls, patients with CSD would show altered functioning in brain regions that are thought to be important in CSD. All participants were right-handed, as assessed via the Edinburgh Handedness Inventory (Oldfield, 1971). History of quiescent or fully compensated vestibular peripheral deficits at the time of study was not an exclusion criterion.
Four sessions (2 for the left and 2 for the right ear) including 4 blocks per stimulus type were presented in approximately 16 min.

CSD may be precipitated by neuro-otological, psychiatric, and other medical conditions that cause acute attacks of vertigo, unsteadiness, or dizziness (Staab and Ruckenstein, 2007). This shift may represent the cortical substrate of visual dependence, that consists of greater reliance on visual cues for spatial orientation and was associated with the type of persistent dizziness seen in CSD (Cousins et al., 2014).
Finally, the severity of dizziness symptoms in CSD patients was measured with the Dizziness Handicap Inventory (DHI) (Jacobson and Newman, 1990). Otogenic illnesses are known to be the most common triggers of CSD (Staab and Ruckenstein, 2003, 2007), and this was the case in our patient sample as vestibular neuritis (N = 12), benign paroxysmal positional vertigo (N = 4) or both (N = 2) represented the main triggers of CSD. Critically, the same STB stimuli delivered at 65 dB SPL do not evoke VEMPs (Todd et al., 2014). The order of sessions and side of first ear stimulated were counterbalanced across participants. Anomalous interactions between the central vestibular system and neural structures related to anxiety may sustain it. However, these events trigger rather than cause CSD and are not sufficient to sustain the disorder. Furthermore, a recent functional magnetic resonance imaging (fMRI) study in healthy volunteers exposed to sound-evoked vestibular stimulation showed that high neuroticism and introversion scores were associated with changes in activity and connectivity in brain areas belonging to vestibular and anxiety circuits (Indovina et al., 2014).


These disturbances were localized on the right side (N = 10), left side (N = 7), or bilaterally (N = 1). Vestibular- and anxiety-related processes overlap in the brain, particularly in the insula and hippocampus. Hence, to investigate how CSD might influence reactivity within the vestibular system, we compared responses to identical STBs at 100 dB and 65 dB SPL. Throughout the experiment, participants were asked to fixate a central point at the center of the screen, and were told to attend to auditory stimuli and report how many types of stimuli they heard at the end of the experiment.
Alterations in activity and connectivity in these brain regions in response to vestibular stimuli may be the neural basis of CSD. To control for non-specific brain responses to sound, we also employed white noise stimuli at 100 dB SPL (Indovina et al., 2014, 2015).
We examined this hypothesis by comparing brain activity from 18 patients with CSD and 18 healthy controls measured by functional magnetic resonance imaging during loud short tone bursts, which are auditory stimuli that evoke robust vestibular responses. White noise stimuli were sinusoidally modulated signals that reproduced the time variability and the SPL of STBs (3 peaks per second, 100 dB RMS SPL). Relative to controls, patients with CSD showed reduced activations to sound-evoked vestibular stimulation in the parieto-insular vestibular cortex (PIVC) including the posterior insula, and in the anterior insula, inferior frontal gyrus, hippocampus, and anterior cingulate cortex. Patients with CSD also showed altered connectivity between the anterior insula and PIVC, anterior insula and middle occipital cortex, hippocampus and PIVC, and anterior cingulate cortex and PIVC.
We conclude that reduced activation in PIVC, hippocampus, anterior insula, inferior frontal gyrus, and anterior cingulate cortex, as well as connectivity changes among these regions, may be linked to long-term vestibular symptoms in patients with CSD. Furthermore, altered connectivity between the anterior insula and middle occipital cortex may underlie the greater reliance on visual cues for spatial orientation in CSD patients relative to controls.
