Fifteen panic disorder patients with prominent dizziness underwent audiologic, caloric, and vestibuloocular reflex activity testing and were compared with normal controls. There were no abnormalities detected on audiologic and caloric tests. Compared with normal controls, panickers with dizziness showed a greater discrepancy between eye and head movements on vestibulo-ocular reflex activity in the dark. Panickers with prominent dizziness did not differ from a second control group of panickers with severe heart palpitations on a number of psychological tests. The results did not support the hypothesis that organic dizziness is etiologically important in the causation of panic or agoraphobia, but do suggest that vestibuloocular reflex activity should be further studied in panic disorder.
