Migraines Patient Education
THE BASICS: “What is a migraine headache?”
A migraine headache (“migraine”) is an intensely throbbing headache, often in only one part of the head. It may occur as often as daily or only once or twice a year. It may last for only a couple of hours or for days. But however long it lasts, a migraine typically causes severe, even disabling, pain.
- About 10 percent of people worldwide suffer from migraines.
- The World Health Organization lists migraines, across the globe, as one of the top 20 causes of disability.
- Up to 5 percent of elementary-school children and about 20 percent of adolescents have migraines.
- Women are more likely to have migraines than men.
Although there is no cure for migraines, medications are available that can:
- Help prevent them
- Help relieve migraine symptoms
Migraines broadly fall into two categories:
- Migraines with aura (formerly called “classic” migraines)
- Migraines without aura (formerly called “common” migraines)
If you have migraines, you may be alerted to the onset of a headache by an aura—visual disturbances such as experiencing temporary loss of vision (for example, side vision) or seeing zigzag lines or flashing lights and/or colors
- An aura may last from 15 to 30 minutes.
- Auras occur in about one-third of migraine sufferers.
- If you have migraines with auras, you may also experience:
- Burning or prickly sensations
- Muscle weakness on one side of your body
- Irritability, restlessness, and/or depression
- Problems communicating with others
The pain may begin in:
- Your forehead
- One side of your head
- In a migraine without aura, the pain may begin on one or both sides of the head.
- Around your eyes
Usually a migraine gets progressively more painful.
- Nausea and vomiting may also occur.
The underlying cause of migraines has not been proved, but genetic factors may play a role.
- Four out of five people with migraines have a family history of it.
What brings on (“triggers”) a migraine is better known. If you have migraines, you may recognize some of these common triggers:
- Certain foods including processed foods, aged cheese, and alcoholic beverages, particularly red wines
- Food-additive triggers, including:
- Monosodium glutamate (MSG), seasoned salt, and meat tenderizers
- Tyramine, sodium nitrate, and phenylalanine
- Loud noises or bright lights
- Strange or strong smells or fumes
- Weather changes
- Changes in altitude
- Stress, anxiety, depression, and/or fatigue
- In women:
- Having a menstrual period
- Using birth control pills
- Experiencing hormonal changes
- Intense physical activity, including sexual activity
- Lack of food or sleep
