Platelet and plasma catecholamine levels in migraine patients: evidence for a menstrual-related variability of the noradrenergic tone
Platelet and plasma levels of catecholamines were measured by HPLC in menstrual migraine patients and controls.

A differential responsiveness of sympathetic nervous system or platelet (or both), linked to hormonal changes, may underlie menstrual migraine and cause predisposition of attacks in the luteal phase
