title: Monoamine oxidase activities in patients with migraine or with cluster headache during the acute phases and after treatment with L-5-hydroxytryptophan.
abstract: The results of a study of the activity of platelet monoamine oxidase (MAO) in patients with migraine or with "Cluster headache" during the acute phases and after treatment with L-5-hydroxytryptophan are presented. MAO levels are higher in migraine subjects than in normals. There is, also, a clear difference between basal MAO levels in migraine sufferers and in Cluster Headache sufferers. The treatment with L-5-hydroxytryptophan tend to normalize MAO activity in the migraine patients, but does not change the MAO activity in cluster headache patients.
