migraine(ˈmiːgrein) , ((American) ˈmai-) nounmigraine→ 偏头痛zhCNmigraineenUKmigraine(mī`grān), headache characterized by recurrent attacks of severe pain, usually on one side of the head. It may be preceded by flashes or spots before the eyes or a ringing in the ears, and accompanied by double vision, nausea, vomiting, or dizziness. The attacks vary in frequency from daily occurrences to one every few years.Migraine affects women three times as often as men and is frequently inherited. Many disturbances, such as allergy, temporary swelling of the brain, and endocrine disturbances, have been suspected of causing some varieties of the disorder. Although the exact cause is unknown, evidence suggests a genetically transmitted functional disturbance of cranial circulation. The pain is believed to be associated with constriction followed by dilation of blood vessels leading to and within the brain. Untreated attacks may last for many hours. Mild attacks are often relieved by common sedatives such as aspirin or codeine. Severe attacks may be treated with any of a variety of drugs, including a group called triptans, by injection or in the form of pills or nasal sprays. Certain beta-blockers, antiepileptic drugs, or tricyclic antidepressants may reduce the recurrence of migraines in some patients. Biofeedback is used in training people to recognize the warning symptoms and to practice control over the vascular dilation that initiates attacks. Migraine(also hemicrania), a condition characterized by periodic headaches, usually localized in one half of the head. Women are most often affected by migraines, and in the majority of cases there is a hereditary tendency. The condition usually begins to manifest itself during puberty. Migraines originate with changes in the tonus of intracranial and extracranial vessels. It is conjectured that first there is a spasm in the vessels and then a decrease in their tonus. As a result, the vessels dilatate abnormally. The headache attacks are accompanied by nausea, vomiting, and photophobia. Other symptoms include pallor or flushing, chilled hands and feet, weakness, shivering, and yawning. Patients usually complain of seeing bright flashes and zigzag lines; sometimes there is reduction or dimness of vision (ophthalmic migraine). Other symptoms are numbness of or tingling sensations in the extremities and, sometimes, the face and tongue. The symptomatic migraine is an indication of organic brain disease—for example, tumor, or vascular aneurysm. Treatment entails normalization of vascular tonus, sedatives, and physical therapy.

KARLOV migraine[′mī‚grān]migrainemigraineenUKmi·graine(mī'grān, mi-grān'),migraineAn 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). migraineHemicrania, sick headache Neurology An intense idiopathic, episodic, uni/bilateral, pulsating–vascular headache, often exacerbated by physical activity, linked to dilation of branches of the carotid artery Clinical 'Classic' migraines are most common in ♀ 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 N&V, photophobia, other visual phenomena–eg, hemianopia, scotomas, fortification phenomenon, phonophobia Treatment Analgesics–eg, aspirin, acetaminophen, propoxyphen, codeine, NSAIDs–eg, naproxen, ibuprofen, ketorolac, 5-HT agonists–eg, ergotamine, sumatryptan, dopamine antagonist–eg, chlorpromazine, metoclopramide Prevention Avoid precipitating factors; if conservative measures fail and the attacks are > 1/wk, pharmacologic prophylaxis is indicated, which may be 5-HT-influencing–eg, amitriptyline, methysergide, β-adrenergic antagonist–eg, propranolol, metoprolol, calcium channel blocker–eg, nifedipine, verapamil, NSAIDs–eg, ketoprofen, mefenamic acid, aspirin, sumatriptan.

The widening is preceded by partial closure of these arteries (spasm) and this often causes temporary disturbance of brain function. Most commonly, this takes the form of an expanding, one-sided blank area in the field of vision, with a sparkling (scintillating) jagged border. Such an episode usually lasts for about 20 min. Other neurological disturbances may occur, such as weakness or loss of sensation on the face or down one side of the body or speech or comprehension defects. The headache that follows these effects may be severe and there is nausea and sometimes vomiting and great intolerance to light. Migraine is treated with various drugs including ergotamine tartrate, beta-blockers such as PROPRANOLOL, antidepressants such as amitryptyline, and the serotonin antagonist METHYSERGIDE. The term migraine comes from the words ‘hemi-cranial’, meaning half-head.Migrainemigrainemi·graine(mī'grān)Patient discussion about migraineQ. what is migraine??? Q. What the reasons to the migraine?
