(HealthDay News) -- A migraine headache can be so painful that it prevents you from doing most daily activities.
About 12 percent of Americans get frequent migraines, the U.S. National Library of Medicine says. Sufferers are more likely to be women, have a family history of migraines or have other medical conditions, such as depression, anxiety, bipolar disorder, sleep disorder or epilepsy.
The agency says common triggers include:
- Hormonal changes in women.
- Bright or flashing lights.
- Loud noises.
- Strong smells.
- Inconsistent sleep patterns.
- Too much physical activity.
