Pathophysiological aspects of menstrual migraine.
We review the role of several biochemical and hormonal factors in menstrual migraine pathogenesis: ovarian hormones, aldosterone circadian rhythm, nocturnal urinary melatonin excretion, sympathetic autonomic system, prolactin levels and dopaminergic function, endogenous opioid tonus, platelet activity and arachidonic acid metabolites. In particular, we focus on certain aspects of platelet function and prostaglandin metabolism, taking into consideration the different behavior of platelet sensitivity to prostacyclin, intraplatelet 5HT, peripheral plasma concentrations of 6-keto-PGF1alpha and PGE2 in menstrual migraine sufferers and in control subjects during the menstrual cycle. A comprehensive view of the data suggests that a complex impairment of PG and 5HT metabolism, and of platelet function, may play a significant role in the pathogenesis of menstrual migraine. However, it is not yet clear whether these alterations are primary or secondary to neuroendocrine disorders.
