Basilar artery blood flow was measured by transcranial Doppler ultrasonography before and during hyperventilation in nine patients with panic disorder and nine normal comparison subjects. The hyperventilation-induced decrease in basilar artery blood flow was significantly greater in patients with panic attacks than in comparison subjects. Two patients with decreases in basilar flow greater than 80% were successfully treated with nimodipine, a centrally active calcium channel blocker.
