Migraine

Migraine: Introduction

A migraine is a specific type of headache that is severe, persistent and often occurs in conjunction with a wide variety of symptoms. Migraines can be so severe that they can be disabling in many cases, leading to serious disruption of work, school, relationships, and social activities.

Migraines are the result of a constriction of the arteries in the brain, which reduces blood flow to the brain. This is followed by dilation or widening of these arteries. This process results in the classic symptoms of migraine that include sensory disturbances and headache. For more information on symptoms and complications, refer to symptoms of migraine.

Migraines are often, but not always, triggered by one or more specific substances or situations. These can vary greatly from person to person. Common triggers include chocolate, caffeine, alcohol, red wine, and aged cheese, sausages and other aged foods. Certain food additives, such as monosodium glutamate, nitrates and nitrites can also elicit a migraine. Other common triggers include allergies, emotional stress, bright lights, fluorescent lights, high altitudes, extreme exertion, and extreme changes in weather. In some women hormonal changes due to the menstrual cycle can trigger migraines. Migraines are more common in women than in men.

Making a diagnosis of migraine includes performing a complete evaluation that includes a medical history, including symptoms, and physical examination. This includes a neurological examination. A neurological exam evaluates the brain and nerves and such functions as level of consciousness, reflexes, sensation, movement, balance, coordination, vision, and hearing. This can help to differentiate between a migraine and other neurological conditions, such as stroke. A referral to a neurologist, a specialist in treating neurological conditions, is generally made for definitive diagnosis and treatment of migraine.

Because many people with migraines have visual disturbances, an eye examination is performed to rule-out such eye conditions as detached retina. An eye examination includes testing visual acuity or sharpness of vision, checking the sharpness of peripheral vision, and testing the pressure inside the eye. The outer eye is examined using an instrument called a slit lamp, and the inner eye is examined using an instrument called an ophthalmoscope. During the exam with an ophthalmoscope, the pupils of the eye may be dilated (opened up) with a drop of medication to better visualize any changes in the retina.

The diagnostic process also involves keeping a migraine log or diary to record the timing, symptoms, and the types of situations that occurred or substances that were ingested before the migraine occurred. This can help to diagnose triggers and assist in making lifestyle changes that can minimize migraine headaches. The type of treatment and its results are also recorded to help pinpoint the most effective treatment for an individual.

It is possible that a diagnosis of migraine can be missed or delayed because symptoms can be similar to symptoms of other conditions and diseases, such as stroke and transient ischemia attack. For more information on diseases and conditions that can mimic migraine, refer to misdiagnosis of migraine.

Patient compliance with a good treatment plan can control symptoms of migraine to a degree that allows a person to live a normal active life. Treatment plans include medications and avoiding substances and situations that can trigger a migraine. For more information on treatment, refer to treatment of migraine. ...more »

Article Excerpts about Migraine

The most common type of vascular headache is migraine. Migraine headaches are usually characterized by severe pain on one or both sides of the head, an upset stomach, and at times disturbed vision. (Source: excerpt from Headache -- Hope Through Research: NINDS)

Definitions of Migraine:

A subtype of vascular headaches characterized by periodic unilateral pulsatile headaches which begin in childhood, adolescence, or early adult life and recur with diminishing frequency during advancing years. The two major subtypes are CLASSIC MIGRAINE (i.e., migraine with aura) and COMMON MIGRAINE (i.e., migraine without aura). Migrainous episodes may be associated with alterations in cerebral blood flow. (From Adams et al., Principles of Neurology, 6th ed, p172) - (Source - Diseases Database)

A severe recurring vascular headache; occurs more frequently in women than men - (Source - WordNet 2.1)
