migraine

An intense idiopathic, episodic, uni/bilateral, pulsating (vascular) headache, often exacerbated by physical activity, linked to dilation of branches of the carotid artery.

Clinical findings
Classic migraines are most common in women age 30–49 and in lower income households, and appear to have a hereditary component. Migraines first appear before puberty and remit at menopause; they may be accompanied or preceded by nausea, vomiting, phonophobia, and photophobia or other visual phenomena (e.g., hemianopia, scotomas, fortification phenomenon).

Management
Analgesics (e.g., aspirin, acetaminophen, propoxyphen, codeine), NSAIDs (e.g., naproxen, ibuprofen, ketorolac), 5-HT agonists (e.g., ergotamine, sumatryptan), dopamine antagonist (e.g., chlorpromazine, metoclopramide).
 
Prevention
Avoid precipitating factors; if conservative measures fail and the attacks are > 1/week, pharmacologic prophylaxis is indicated, which may be 5-HT influencing (e.g., amitriptyline, methysergide1), β-adrenergic antagonist (e.g., propranolol, metoprolol), calcium channel blocker (e.g., nifedipine, verapamil) or NSAIDs (e.g., ketoprofen, mefenamic acid, aspirin).

mi·graine

(mī'grān)
A symptom complex occurring periodically and characterized by pain in the head (usually unilateral), vertigo, nausea and vomiting, and photophobia. Onset of pain may be preceded by a warning (i.e., aura), often consisting of bilateral scintillating scotomas. Subtypes include classic migraine, common migraine, cluster headache, hemiplegic migraine, ophthalmoplegic migraine, and ophthalmic migraine.
Synonym(s): hemicrania (1) , sick headache.
