Menstrual migraine (MM) is a menstrually related disorder (MRD) charac
terized by several symptoms in common with premenstrual syndrome (PMS)
. It has been hypothesized that in both MM and PMS hormonal cyclicity
could change the balance of neurotransmitters and neuromodulators like
monoamine and opioid. In this article we analyze all the data collect
ed by our group on the central opioid tonus and the adrenergic and ser
otonergic systems in patients affected by menstrual migraine.
