To investigate the comorbidity of premenstmal syndrome (PMS) and menst
rual migraine, the Menstrual Distress Questionnaire (MDQ) was prospect
iveiy administered for two consecutive menstrual cycles to 22 patients
with menstrual migraine, 12 cases with migraine without aura and 15 p
atients with PMS. MDQ scores varied throughout the menstrual cycle in
each patient group, the wider changes being shown by patients with PMS
. Fourteen menstrual migraine patients and 4 migraine without aura pat
ients achieved diagnostic criteria for PMS over two menstrual cycles.
In these patients MDQ scores did not differ from PMS sufferers at any
stage of the menstrual cycle. The premenstrual increase of each cluste
r of PMS symptoms was identical in menstrual migraine and PMS subjects
with the exception of negative affect. We suggest that PMS symptoms s
hould be taken into account in the IHS diagnostic criteria for menstru
al migraine.
