What is a migraine?
A migraine is a chronic headache characterized by repeated, intense, throbbing pain either on one side or both sides of the head. Most people with migraines feel pain in one eye, ear, or the temples.
About 25% of people with migraines experience aura. An aura is a migraine-specific symptom (usually tingling of arms, seeing flashes of light, or zigzag lines) that precede the migraine or accompanies it.
Migraines can occur at any time of the day, although in many cases they start in the morning. The pain may last for a few hours or up to one to two days. The frequency of a migraine attack varies from individual to individual. In some, it may occur once or twice a week, whereas, in others, it may occur once or twice a year. Migraine significantly diminishes a person’s quality of life.
Migraine is the third most prevalent disease and affects about one billion people worldwide.
What causes migraines?
The exact cause of migraines is unknown. Researchers think that migraine occurs because of an increase in the level of neurotransmitters, chemicals that send messages among the brain cells, in the brain.
This increase in neurotransmitters is believed to create overactive nerve cells, which in turn send signals to the trigeminal nerve that is responsible for the sensation in the head and face. Activation of the trigeminal nerve leads to the release of a set of chemicals that cause the blood vessels to swell and pain.
People with migraines react to a variety of factors and events, known as triggers. A combination of triggers may set off an attack.
