A migraine is a throbbing painful headache, usually on one side of the head, that is often initiated or"triggered" by specific compounds or situations (environment, stress, hormones, and many others). They occur more often in women (75%, approximately) and may affect a person’s ability to do common tasks.
Migraine Symptoms, throbbing pain, usually on one side of a person's head, can be intense enough to cause a person to be unable to do simple tasks or to work. The headache pain may radiate toward the eyes, forehead, or temple and make a person develop nausea, vomiting, vision problems, and sensitivity to normal light or mildexertion.
Migraine With Aura"Classic" migraines begin with an aura such as seeing visual field changes (dots, wavy lines, blurriness) about an hour or less before the pain begins. Approximately 20% of people with migraines have this "classic" type.
Migraine Warning Signs"Classic" auras do not occur in all patients, but about 25% of migraine patients can have a prodromal phase. The prodromal phase occurs as long as 24 hours before migraine pain develops; the prodromal phase consists of mood changes (depressed, excited, irritable) and sensations of odd smells or tastes, while others may feel tired or tense.
What Causes a Migraine? The neurological causes of migraines are not understood but researchers speculate something may initiate a mix of blood vessel permeation and brain chemicals to interact with brain cells to cause the migraine.
