Migraine.

The most widely accepted classification of the migraine syndrome includes common, classic, complicated and cluster migraines. Migraine variants refer to episodic dysfunctions of an organ or system which either occur in the migraine sufferer, or replace the headache. While migraine appears to be a primary disorder of the cerebral vessels, there is current experimentation into the role of circulating serotin, prostaglandins, platelet abnormalities and estrogen levels. Both nonnarcotic and narcotic treatments are available, and prophylactic measures may be indicated.
