A prospective study of the headache phase in 32 migraine with aura patients.

For an accurate description of the clinical features of the headache phase in migraine with aura (MA) attacks, we thought it useful to conduct a prospective study of consecutively referred MA patients seeking treatment at the Headache Centre of the University of Parma Institute of Neurology. The case series included 32 patients (22 women and 10 men). At the time of the first visit, each patient was given a questionnaire to be filled in at the next MA attack. Six patients (four women and two men) had attacks of migraine aura without headache. Among the remaining 26 patients (18 women and eight men), the duration of the headache phase was <24 h in 23 (88.5%); pain location was bilateral in 14 (53.8%) and unilateral in 12, but occurring on the opposite side to aura only in one patient; pain intensity was mild or moderate in 13 (50.0%). The headache phase of MA appeared to have clinical features that differed widely from patient to patient and was consistent with the International Headache Society diagnostic criteria for migraine without aura in 26.9% of patients and for tension-type headache (TTH) in 23.1%.
