Abstract

SYNOPSISThree patients with chronic paroxysmal hemicrania (CPH) (1 M, 2 F) and 9 healthy controls (8 M I F) were studied with transcranial Doppler (TCD) sonography. One patient who was studied during the spontaneous attacks hyperventilated markedly. Middle cerebral artery velocity (V_MCA) was measured in the first attack, and anterior cerebral artery velocity (V_ACA) in the second attack, respectively. V_MCA and V_ACA decreased bi‐laterally during attack. V_MCA started to decrease at an early stage of the attack, i.e. prior to the major hyperventilation that was observed during the attack. V_ACA on the symptomatic side decreased less than that on the other side (P0.05) in comparison with controls. These observations may imply an abnormal vascular reactivity in CPH.
