The literature of headache is convergent in pointing to low levels of melatonin in patients with migraine and cluster headache. Treatment of headache disorders with melatonin and other chronobiotic agents is promising. Some trials showed that melatonin was effective in cluster headache and migraine prevention but future studies are necessary for the better understanding of the role of melatonin in headache disorders treatment.
