Abstract

Computerized EEG frequency analysis was performed in 18 patients with peripheral vestibular dysfunction (PVD), 17 patients with central vestibular dysfunction (CVD) and 22 aged matched controls. Increase in the relative theta activity in the centrotemporal region was found in patients with PVD. The decrease of centroparietal beta activity in both groups of patients, as compared to controls, did not reach statistical significance. We conclude that quantified EEG may be a sensitive method to show changes of cortical electrical activity in patients with vertigo, reflecting the imbalance in afferent vestibular input to the cortex.
