Patients with orthostatic dysregulation (OD)-associated disease may show autonomic disorders more frequently as compared with patients with other types of dizziness. However, the pathological mechanisms of OD remain unclear. We examined the cardiovascular autonomic function in dizzy patients with postural orthostatic tachycardia syndrome (POTS) or chronic orthostatic intolerance (OI) in order to evaluate the contribution of the autonomic disorders to the occurrence of dizziness. Heart rate variability analysis during the Schellong test showed that patients with POTS have hypo-parasympathetic function and relative hyper-sympathetic function, and that some patients with OI also have hypo-parasympathetic function. In our clinic, single therapy with a β1-blocker (Atenolol) for patients with POTS or single therapy with an a- agonist for patients with OI relieved orthostatic symptoms in 60% of the patients with POTS and OI. Further clinical studies on OD-associated disease to evaluate methods for accurate diagnosis and appropriate combined physical and pharmacotherapy may improve the outcomes in patients with OD-associated disease.

<p> The cause of vertigo/dizziness varies. We may reduce vertigo/dizziness with a nutritional approach involving the circadian rhythm and chrononutrition. We can avoid hypoglycemia-mediated vertigo/dizziness by modulating the glucose intake. We can prevent anemia-mediated vertigo/dizziness through dietary supplementation with iron, copper, and vitamin C. Supplementary calcium and zinc are effective for the prevention of psychogenic vertigo/dizziness. In addition, it is effective to enforce a low salt diet at breakfast and lunch. The effective intake-time of calcium is about 1.5 hours before sleep. It is necessary to regulate one's lifestyle, and to prevent diabetes, high blood pressure, dyslipidemia and obesity. We can reduce vertigo/dizziness by preventing edema. A genetic investigation in conjunction with obesity is also necessary. A nutritional approach based on the results of a genetic analysis can be effective for prevention of obesity. Controlled eating habits through nutrition/dietetics can help in the prevention of vertigo/dizziness.</p>

By means of noisy galvanic vestibular stimulation (GVS), it might be possible to ameliorate the blunted responsiveness of degenerated neuronal circuits in patients with degenerative neurological diseases. We evaluated the effects of 24-hour noisy GVS on the long-term heart rate dynamics in patients with multiple system atrophy and on the daytime trunk activity dynamics in patients with either levodopa-responsive Parkinson's disease or levodopa-unresponsive parkinsonism patients. Patients were also examined for cognitive performance by means of a continuous performance test. Short-range or high-frequency fluctuations of the heart rate were significantly increased by the noisy GVS as compared with that by sham stimulation, suggestive of improved autonomic, especially parasympathetic, responsiveness. The long-range anti-persistency of trunk activity patterns probed by an autocorrelation measure was significantly increased by the noisy GVS, suggestive of quickening of bradykinesic rest-to-active transitions. The mean reaction time in the continuous performance test was also significantly decreased by the noisy GVS, without significant changes in either the omission or commission error ratios, which is suggestive of improved motor execution during the cognitive task. Thus, noisy GVS improved the motor and autonomic responsiveness and is effective for ameliorating the symptoms in patients with multiple system atrophy or Parkinson's disease.

Herein, we present a patient with superior semicircular canal dehiscence syndrome (SCDS) manifesting as convergence spasms, which were alleviated by canal plugging surgery. SCDS is described in the literature by Minor as “a condition characterized by vertigo and oscillopsia induced by loud sounds or changes in the pressure of the external auditory canal or middle ear due to the dehiscence of the bone overlying the superior semicircular canal.” Convergence spasms are characterized by intermittent sustained convergence, accommodative spasms and miosis, and are likely to be caused by a functional disease, although in some cases, it is a manifestation of an organic disease. A 49-year-old male patient visited our department with a 2-year history of intermittent sudden vertigo and cloudy vision. The vertigo attacks had gradually increased in frequency and could last all day. Pure-tone audiometry showed bilateral conductive hearing impairment with air-bone gap at low frequencies from 125Hz to 500Hz. A head CT showed bone dehiscence above the bilateral superior semicircular canals and tegmen of the epitympani. Initial equilibrium testing did not reveal any abnormal findings. Initial sono-ocular testing of the right ear indicated upbeat nystagmus. However, after multiple outpatient visits, the upbeat nystagmus disappeared during the sono-ocular test and was replaced by paradoxical convergence. The eye tracking test also revealed paradoxical convergence, which became frequent and was accompanied by pupillary miosis. This paradoxical convergence was ultimately diagnosed as convergence spasms. No improvement of symptoms was achieved through non-surgical treatments over an extended period of time, therefore, canal plugging surgery was recommended. The surgery was performed through a middle fossa approach, and it completely eliminated the cochlear and vestibular symptoms associated with SCDS and the convergence spasms. Finally, we suspected that the convergence spasms were caused by ocular dysfunction as well as neurological factors related to the SCDS.

To clarify the dynamic changes in the membranous lesions of Meniere's disease, the effects of aerobic exercise on different symptoms were analyzed. Out of a total of 351 patients with Meniere's disease who performed aerobic exercises for 6 months or longer who were enrolled, 338 showed improvement of one or more symptoms: disappearance of vertigo in 97.6% of cases; complete resolution of ear fullness in 60.1% of cases; improvement of hearing impairment in 38.5% of cases; complete resolution or marked decrease of tinnitus in 29.6% of cases. On the other hand, complete recovery of hearing was noted in 29.5% of the 78 patients with low-tone loss, 12.5% of the 96 patients with high-tone loss, and only 4.1% of the 170 patients with hearing loss across all frequencies. More than half of the patients with high-tone hearing loss and hearing loss across all frequencies failed to show any change in the degree of hearing loss. Considering the findings of temporal bone pathology, it seems probable that the Reissner's membrane, being ballooned and highly distended by endolymphatic hydrops, disturbs conduction of low-frequency waves by the perilymph, and the membrane, once it loses tension, is not resonant with either high-frequency waves or indeed waves of any frequency. Although aerobic exercise is effective to cure hydrops and improve membranous tension by activating homeostasis, its effect worsens with decreasing membranous tension.

Based on our recent papers (Horii A et al. Otol Neurotol 2004, Horii A et al., J Vestibular Res 2007), we discussed the psychiatric involvement in patients with vertigo and dizziness. Seventy percent of patients with chronic dizziness showed a high score in the Hospital Anxiety and Depression Scale (HADS), suggesting that many dizzy patients have comorbid psychiatric disorders. Fluvoxamine, one of the selective serotonin reuptake inhibitors (SSRIs), administered at a dose of 200mg per day was effective for subjective handicaps due to dizziness in patients with or without neuro-otologic illnesses, owing to its actions on both the comorbid anxiety and depressive disorder. More aggressive psychiatric treatment, such as administration of higher doses, may be the next step of treatment for non-responders without neuro-otologic diseases, because these patients have been shown to suffer from more severe psychiatric illnesses. In contrast, other types of drugs that are known to help recovery of the vestibular function are recommended for neuro-otologic diseases in patients without clinically significant anxiety or depression and non-responders to fluvoxamine. The main causes of dizziness in patients without physical neuro-otologic findings were psychiatric disorders. Bidirectional relationships between vertigo/dizziness and psychiatric disorders could be explained by the anatomical connections between the brainstem and limbic system, including the amygdala.

The purposes of this study was to elucidate the clinical characteristics of patients suffering from migraine-associated vertigo (MAV) including results of cervical vestibular evoked myogenic potential (cVEMP) and ocular VEMP (oVEMP). Thirty patients diagnosed as having MAV based on the diagnostic criteria by Sakata et al. were enrolled. We performed a retrospective chart review. These patients underwent medical history taking and examinations including cVEMP, oVEMP and a caloric test. All examinations were performed during a symptom-free interval. Twenty one patients (70%) experienced rotatory vertigo, 5 patients (17%) had floating dizziness and 4 patients (13%) had both. Twenty six patients (87%) reported tinnitus and/or aural fullness unilaterally or bilaterally. Their vertigo or dizziness lasted under 60 minutes in 10 patients (34%), 1 hour to 24 hours in 14 patients (46%), and over one day in 5 patients (17%). Canal paresis in the caloric test was observed in 5 patients (17%). Concerning cVEMP, 4 of the 30 patients (13%) showed absent cVEMPs bilaterally, 2 patients (7%) showed absent cVEMPs reflexes unilaterally, and one (3%) demonstrated decreased cVEMP amplitudes unilaterally. Only one patient showed prolonged cVEMP latencies. Concerning oVEMP, 6 of the 30 patients (20%) had absent oVEMP reflexes bilaterally, 2 (7%) had absent oVEMP reflexes unilaterally, and one (3%) had decreased oVEMP amplitudes unilaterally. In 2 patients prolonged oVEMP latencies were observed. No significant correlation was observed among cVEMP, oVEMP and the caloric test. This study showed abnormal vestibular reflexes could be shown by oVEMP as well as the caloric test and cVEMP. It was suggested that a portion of those patients with MAV have abnormal otolith-ocular reflexes.

In collaboration with otologists and psychotherapists, psychotherapy was performed together with the administration of drugs for patients with Meniere's disease in whom medical treatment, surgical treatment, or intratympanic streptomycin therapy had been ineffective and for a patient with intractable tinnitus. We report in detail 7 patients for whom psychotherapy was effective for vertigo, stabilization of hearing fluctuation, or the acceptance of tinnitus.<BR>It is important to consider psychosomatic aspects in the treatment of patients with Meniere's disease, and it was possible to avoid unnecessary surgery in some Meniere's disease patients using a combination of psychotherapy with medication.

Brainstem disorders are often characterized by abnormal eye movements, however, the type of abnormal movements vary depending on the localization and severity of the damage. Here, we report a case of pontine hemorrhage who exhibited horizontal conjugate gaze palsy and disorder of speech discrimination. The 34-year-old man presented with eye pain and dull feeling malaise?, disorder of speech articulation and torpor paralysis ?? of the left side of the body of sudden onset, that developed while he was driving a car. Clinical examination revealed horizontal conjugate gaze palsy, both rightward and leftward, while vertical gaze and convergence were normal. Although the pure-tone audiogram and DPOAE were within normal range, ABR showed prolongation of latency, and reduction of speech discrimination was recognized. MRI revealed evidence of hematoma and edema extending from the mid-dorsal aspect to the right side of the pons. Based on the findings, the patient was diagnosed to have pontine hemorrhage due to hypertension affecting the right facial nerve nucleus, right pyramidal tract, bilateral abducens nuclei, MLF, PPRF and the auditory neural pathway. Although the symptoms of pyramidal tract and auditory disorder resolved by day 19 when he was?? moved to another hospital, the other neurological symptoms were persistent.

We investigated the influence of a cold front (CF) on the onset of Meniere's disease (MD) and concluded that the onset of MD was influenced by the passing of a CF. But it was not clear whether patients with MD were stressed by the passing of a CF or the passing of a CF directly influenced the inner ears. Among the patients with MD who visited the Neuro-Otological clinic of the Toyama Medical and Pharmaceutical University Hospital from 1987 to 1992, 67 were sure of the date of the first attack and were chosen for the study. In 36 the first attack was on a day when a CF was passing or on the next day, so they were studied epidemiologically.<BR>1) Age: more of these 36 patients were over 40 years of age than in the group of 31 patients with no definite relationship between CF and MD.<BR>2) Hearing: in the 36 patients hearing was poorer than in the others.

The characteristic symptoms of Meniere's disease are recurrent vertigo, fluctuating hearing loss and tinnitus, and the principal underlying pathology is endolymphatic hydrops (ELH). Imaging of endolymphatic hydrops is now possible by 3-Tesla MRI after intratympanic (IT) or intravenous injection (IV) of gadolinium (Gd). 3D-FLAIR and 3D-real IR are obtained in the case of IT injection of contrast, while heavily T2-weighted 3D-FLAIR and HYbriD of Reversed image Of Positive endolymph Signal and native image of positive perilymph signal (HYDROPS) are obtained in the case of IV injection of contrast, to visualize the endolymphatic space. Higher concentrations of the contrast agent can be introduced into the perilymph by IT injection than by IV injection. However, the IV method is preferable in the clinical setting, as the endolymphatic spaces of both ears can be evaluated after a single intravenous injection of Gd. ELH is observed more frequently in patients with definite Meniere's disease than in those with possible Meniere's disease. ELH is observed in both the cochlea and the vestibule in patients with atypical Meniere's disease. The vestibular Meniere's disease patients show significant vestibular predominance in the distribution of ELH. ELH is observed more frequently in patients with fluctuating tinnitus than in patients with stable tinnitus. Examination of ELH can be performed as part of preoperative evaluation prior to stapes surgery in patients with otosclerosis; the presence of ELH is a risk factor for the development of severe vertigo after stapes surgery. Examination to detect vestibular ELH can be helpful in the differential diagnosis between vestibular migraine and vestibular Meniere's disease. MRI is a sensitive technique for detecting ELH and the relationships between ELH and clinical symptoms are expected to be widely investigated using this technique.

A histopathological feature of Meniere's disease is endolymphatic hydrops. Furthermore, a human temporal bone study has revealed that the endolymphatic sac showed fibrosis and/or hypoplasia in a patient with Meniere's disease. Based on this histological finding, malfunction of the endolymphatic sac may cause endolymphatic hydrops. However, it is impossible to explain the fluctuation of Meniere's symptoms with this retention hydrops, so the mechanisms underlying the endolymphatic hydrops of Meniere's diseases is still unclear. Clinically, it is well known that stress aggravates the condition of Meniere's disease. It seems to be that there are some relationships between stress and endolymphatic hydrops. Endolymphatic hydrops could be taken as malfunction of water homeostasis in the inner ear. If this is the case, one of stress hormones, vasopressin, could regulate water homeostasis in the inner ear. Actually, plasma vasopressin levels have been reported as elevated in patients with endolymphatic hydrops including Meniere's disease. Experimentally, vasopressin type 2 receptor was expressed in the basal cell of the stria vascularis. Moreover, the water channel of aquaporin (AQP) 2, the relocalization of which is regulated by vasopressin, was also expressed in the stria vascularis. Further, other AQPs were also expressed in the stria vascularis. To investigate the effect of vasopressin on the inner ear, vasopressin was administered to rats or guinea pigs. Vasopressin induced enlargement of the intrastrial space and endolymphatic hydrops. These results indicate that vasopressin affects the stria vascularis and endolymphatic hydrops was induced as a consequence. The following is a summary. Basically, patients with Meniere's disease have malfunction of the endolymphatic sac with retention hydrops. If the patients are under stress, the secretion of vasopressin would increase. The increase of vasopressin level causes the enlargement of the endolymphatic hydrops. These conditions may induce the symptom of Meniere's disease. Based on these clinical and experimental results, we produced a new animal model for Meniere's disease with vestibular disorder.

Introduction: The vertigo symptom scale-short form (VSS-sf), which has three factors, the vestibular-balance symptom with long duration, the vestibular-balance symptom with short duration, and the autonomic symptom, was developed for measurement of the therapeutic effect in vestibular diseases. However, clinical use of the VSS-sf has not been reported in Japan, and there are very few analyses using scores of the factors or each item of the VSS-sf. The aims of this study is to report both clinical use of the VSS-sf in Japan and analyses using scores of the factors or each item of the VSS-sf. Methods: Participants included both adult inpatients and outpatients with either non-central dizziness/vertigo or vertebrobasilar insufficiency which occurred more than one month before, diagnosed by expert neuro-otologists. Participants completed three questionnaires: the VSS-sf, the dizziness handicap inventory, and the hospital anxiety and depression scale (HADS). We conducted a multiple regression analysis with the scores of the three factors of the VSS-sf, to evaluate how much influence there was from vestibular and autonomic symptoms on any handicap due to dizziness. We analyzed the scores of each item of the VSS-sf to examine profiles of the symptoms in major vestibular diseases. Results: The results of 159 participants were analyzed. Standard partial regression coefficients of anxiety, depression, and the vestibular-balance symptom with long duration were significant, however, those of the vestibular-balance symptom with short duration and the autonomic symptom were not. Most frequent autonomic symptoms were headache, chill/flashes, and palpitation in Ménière's disease, benign paroxysmal positional vertigo, vestibular neuronitis, and psychogenic dizziness. Conclusion: The VSS-sf can be conducted without major problems in Japan, and may be useful for patients with vestibular diseases, not only to measure therapeutic effect but also to analyze the influence of, or relation between the vestibular-balance symptom/autonomic symptoms and other clinical variables.

Patients with chronic dizziness often complain of headache; conversely, patients with headache complain of dizziness. Patients with migraine complain of dizziness more often than patients with tension-type headache. Diagnostic criteria for both Meniere disease and vestibular migraine have been reported recently. However, in some cases, it is difficult to clearly distinguish between Meniere's disease and vestibular migraine. In the patients complains symptom, which is described in the diagnostic criteria of Meniere disease and vestibular migraine at the same time may define as Patients complaining of symptoms described in both the diagnostic criteria for Meniere's disease and vestibular migraine may be defined as having vestibular migraine and Meniere's disease overlap syndrome. Here, I would like to describe the etiology of migraine and Meniere's disease. In Japan, migraine is reported to occur at a prevalence of 3.6% in men and 12.9% in women, while Meniere's disease is reported to occur at a prevalence of approximately 2-30 cases per 1,000,000 inhabitants. In otorhinolaryngologic? outpatient practice, Meniere's disease and vestibular migraine are reported to account for about 8%-10% of patients. There are no objective tools yet to clearly diagnose either vestibular migraine or Meniere's disease. Recently, the habituation of middle latency response was reported as a potential objective evaluation tool for the diagnosis of vestibular migraine. Further study is required to identify objective tools for the diagnosis of vestibular migraine and Meniere's disease.

The patch clamp technique enables the analyses of various ion channel characteristics of individual cells in vitro. The most important difference from previous techniques is that the microelectrode (pipette) is firmly attached to the cell surface instead of being inserted into the cells, and the so-called "giga-ohm seal" is attained. Usually, the whole conductance of the cell membrane is measured under "whole cell" and "perforated patch" modes, whereas single channel recordings are also possible by employing relevant modes such as the "cell attached" mode. In the most frequently used "whole cell" mode, the intracellular potential (voltage clamp) or the whole cell current (current clamp) can be kept constant, since the leakage current is very small. Exemplary recordings are also shown from the author's experiments.

Abstract: We herein report the rare case of a patient who developed cerebellar infarction due to vertebral artery dissection, initially suspected as a perilymph fistula, immediately after a bout of sneezing. A 61-year-old man developed spontaneous vertigo and tinnitus immediately after a bout of sneezing. Initially there were no obvious findings on head CT, and he was referred to our department as a probable case of peripheral vestibular dysfunction. Since left hearing loss and rightward nystagmus were observed, we initially made the diagnosis of perilymph fistula. However, a repeat CT revealed cerebellar infarction of the region supplied by the posterior inferior cerebellar artery with vertebral artery dissection. This patient had complex mixed symptoms, including peripheral vestibular findings and central nervous system findings. We speculated that this patient might have had infarction of the posterior inferior cerebellar artery region, accompanied by decrease of the blood flow in the anterior inferior cerebellar artery, which caused hearing loss.

This study was conducted to investigate the factors of one foot balancing and beam-walking in persons with intellectual disabilities (ID). There were 181 subjects with ID (male, 126; female, 55; 14 persons with autism; 22 with Down's Syndrome (DS)). One foot balancing was measured with eyes open and with eyes closed. In the beam-walking test, the subjects were asked to walk on five types of beam 3 meters in length. A stepwise multiple regression analysis was used to analyze the results. The dependent variables were the one foot balancing score (sec) with eyes open and with eyes closed and the beam-walking score (from 0 to 5), and the independents were sex, age, height (cm), weight (kg), IQ, presence/absence of autism, and presence/absence of DS. The results were as follows: (1) The one foot balancing with eyes open only related to IQ. Persons with a higher IQ showed a higher score in all the three balance tests than those with a lower IQ. The one foot balancing with eyes closed correlated with IQ and presence/absence of autism. Autistic subjects stood longer than persons with other IDs. The beam walking correlated with IQ, presence/absence of autism, and presence/absence of DS. Autistic subjects attained a higher score than subjects with other IDs, and DS subjects had lower scores. These characteristics of balance in subjects with ID are discussed in terms of executive function, motor dysfunction, and compensatory strategies.
