Migraine headache. Its diagnosis and treatment.

Many theories exist on the pathogenesis of migraine. However, the clinical picture of migraine is agreed on universally as a familial disorder characterized by recurrent attacks of headache that are variable in intensity, frequency, and duration. The attacks are usually unilateral and often associated with anorexia, nausea, and vomiting. Migraine therapy is complex and difficult, focusing on abortive and prophylactic regimens. General therapeutic measures, including diet and establishing schedules for meals and sleeping, may benefit many migraineurs. A variety of medications, including ergotamine, propranolol, the calcium channel blockers, antidepressants, and nonsteroidal anti-inflammatory drugs (NSAIDs) have been beneficial in the prophylactic treatment of migraine. Ergotamine is the drug of choice in the abortive treatment, although other agents, such as the NSAIDs, have been used successfully. Inpatient therapy in a specialized unit for headache patients may be indicated for the recidivist patient, the patient habituated to analgesics or ergotamine, or the patient with the mixed headache syndrome, i.e., migraine occurring with coexistent muscle contraction headaches.
