Cohen HS, et al. - Researchers aimed at reporting the utility of two vestibular test batteries across ages in healthy men and women for identification of vestibular disorders. In addition, they compared the occurrence of vestibular disorders in the healthy adult population and women with human immunodeficiency virus (HIV) disease. They tested healthy controls (284 women and 105 men) and women (63) with HIV/AIDS (HIV+) who are being followed up in a longitudinal study of HIV, on objective diagnostic tests of the vestibular system. As per data gained, decreased vestibular function is evident among people at all ages, even among young, asymptomatic, and apparently healthy adults. An increased prevalence of peripheral vestibular disorders is not caused by HIV disease itself, when HIV is controlled on antiretroviral medication.
