title: Pattern of plasma opioids in menstrually-related migraine and epilepsy.
abstract: Plasma estradiol (E2), progesterone (P), beta-endorphin (beta-EP) and beta-lipotropin (beta-LPH) were measured in the luteal phase of 8 patients affected by menstrually-related migraine (M) and in 3 cases of catamenial epilepsy (CE). Plasma P and E2 of the M patients were lower than in the CE group. Both beta-LPH and beta-EP showed a reduction in M patients near menses, while the opposite pattern was found in CE. These data demonstrate that premenstrual syndrome is sustained by different, neurobiological dysfunction even if endogenous opioids could be involved in both migraine and epilepsy.
