Abstract
A battery of vestibular and audiological tests was administered to 8 patients with panic disorder and 13 patients with agoraphobia and panic attacks, all of whom experienced dizziness during their panic attacks. Positional or spontaneous nystagmus was present in 67% of the subjects. Abnormal responses were found in caloric testing (56%), rotational testing (35%), and posturography (32%). Pure tone audiograms were abnormal in 26% of the subjects and acoustic reflexes were abnormal in 44% of the subjects. Six of 8 patients tested had an abnormal brainstem auditory evoked potential. The possible importance of the findings and their implications for further research are discussed.
