Abstract

Transcranial Doppler (TCD) recording was used to evaluate the mean flow velocity (MFV) and cerebrovascular reactivity to CO2 in 21 migraineurs during the interictal phase. Nine were affected by migraine with aura (MwA) and 12 by migraine without aura (MwoA). During each session the middle cerebral artery (MCA) flow velocity was examined in basal conditions, in hypocapnia after a 3-min period of hyperventilation, in basal conditions a second time, and in hypercapnia after breath-holding. The same procedure was followed in a group of 21 age-and sex-matched volunteers. Recordings were performed before (T1), during (T2), and after (T3) prophylactic treatment with flunarizine (10 mg/day for 2 months) to assess the possible effect of this drug on cerebral hemodynamics. In basal condition, increased MFV values were found in both MwA and MwoA patients. In MwA patients the reactivity index (RI) to hypocapnia was significantly increased in T1 (p
