BACKGROUND No studies to date have attempted to evaluate frontotemporal lobar degeneration from the perspective of the vestibular system. OBJECTIVE The present study examined vestibular function in patients with frontotemporal dementia (FTD) clinical syndrome and evaluated whether vestibular disorders are involved in the clinical symptoms due to FTD. METHODS Fourteen patients with FTD syndr...

UNLABELLED Response inversion during warm air stimulation is the most controversial finding seen in caloric tests of individuals with tympanic membrane perforation. In such cases, very few studies explore the possible interferences found in the caloric test, bringing about controversies in the interpretation of test results. AIM This paper aimed at analyzing warm air stimulation effects in in...

OBJECTIVES Air caloric results are supposed to be influenced by anatomic changes of the middle ear. The aims of our study were to evaluate the incidence and characteristics of abnormal air caloric results in patients with unilateral chronic otitis media and without any history of vertigo, and to compare caloric results with there of other vestibular function tests (VFTs). METHODS Twenty five ...

Vestibular migraine (VM) is one of the most common causes of episodic vertigo. We reviewed the results of multiple vestibular function tests in a cohort of VM patients who were diagnosed with VM according to the diagnostic criteria of the Barany Society and the International Headache Society and assessed the efficacy of each for predicting the prognosis in VM patients. A retrospective chart ana...

IMPORTANCE Vestibular disorders have been reported following cochlear implant (CI) surgery, but the literature shows a wide discrepancy in the reported clinical impact. The aim of this meta-analysis is to quantify the effect of CI before and after surgery on the outcomes of vestibular tests, postural stability, and subjective perception of dizziness. OBJECTIVE To evaluate the effects of CI su...

BACKGROUND To diagnose acoustic neuromas (ANs), the auditory brainstem response test and the caloric test have been used in addition to magnetic resonance imaging. The auditory brainstem response and the caloric tests mainly reflect functions of the auditory pathway, ie, the cochlear nerve and the superior vestibular nerve, respectively. Because the vestibular evoked myogenic potential (VEMP) h...

Vertigo is defined as a subjective sense of imbalance and includes unsteadiness as well as a sensation of rotation. Vertiginous symptoms may arise from defects in the labyrinth, the visual system, or the central nervous system, although in most patients presenting with balance problems, the lesion lies within the labyrinth or its central connections. The most important step in the diagnosis is ...

The vestibular evoked myogenic potential (VEMP) is a promising test of the descending vestibulocollic system. Our aim was to determine whether the VEMP can be applied to an older patient population and can detect lesions in descending vestibulospinal pathways. We also compared VEMP clinical performance with that of the standard caloric test. VEMP test performance was retrospectively analyzed in...

Caloric restriction (CR), the reduced intake of calories without malnutrition, extends lifespan of many organisms, from yeast to mammals, and delays the progression of age-related diseases. Evidence show that hypothalamus is a crucial brain region for the progress of whole-body aging [1] and the beneficial effects induced by CR are regulated by nutrient-sensing neurons located in the hypothalam...
