Melatonin for Migraine Prevention
Melatonin for Migraine Prevention (The MMP-study): A Randomized, Double-blind, Cross-over, Placebo-controlled Study of Melatonin in Prophylactic Treatment of Migraine

The circadian system with its centre in the hypothalamus is involved in migraine pathophysiology. Whether it plays a pivotal role is not clarified. The investigators postulate that a destabilized circadian system may increase migraine attack susceptibility, and that stabilization by supplying melatonin a migraine preventive effect will be achieved.

A previous open label study has shown effects that certainly warrant a placebo controlled study.
