What causes migraine headaches?
The brain cannot “feel” pain. The brain does not have nerve endings (pain sensors), like you have in your fingers or toes. However, there are pain sensors in the blood vessels inside and around the brain and in the tissues that cover the brain. Many doctors think migraines happen when blood vessels in the brain get narrow and when they expand. Some think certain chemicals in the brain cause migraines.
Most agree that different things (called “triggers”) can bring on a migraine attack. Some common triggers are:
- Missing or delaying meals
- Certain foods such as cheese, chocolate, MSG, caffeine, aspartame, nuts, pizza, and processed meat
- Too much or too little sleep
- Weather changes
How will the doctor diagnose my child’s migraines?
A pediatric neurologist will evaluate your child. This includes a history and physical examination. They may also order tests to look for what may be causing the migraines. These may include blood or urine tests, a CT scan, or an MRI of the brain. Usually, the child does not have a serious medical condition.
How will the doctor treat my child’s migraines?
The first step is to make some healthy lifestyle changes. Without these basic health measures, other treatments may not work. Your child should:
- Drink lots of liquids and eat a balanced diet with healthy meals three times a day.
- Take part in enjoyable physical activity for at least 30 minutes a day. Some examples are walking, hiking, playing sports, or swimming.
Your child should see a doctor if:
- Your child has migraines that wake him from a deep sleep.
- Your child develops problems with vision, personality, coordination, or school performance.
- Your child has a sudden migraine that is the worst ever.
- Your child has depression or anxiety.
Get the proper amount of sleep (minimum of eight hours). This is important. Lack of proper sleep often triggers migraines. The next step is to recognize and avoid triggers that cause your child’s migraines. Sometimes triggers are not obvious and cannot be identified. To help figure out what triggers your child’s migraines, doctors often ask parents and older kids and teens to keep a migraine diary. This will show you when migraines happen, how long they last, and what may trigger them.
Occasional migraines are fewer than four a month, last less than 24 hours, and do not interfere with school attendance or other activities. These can be treated with medicine. These medicines work best when given as early as possible after the headache starts. The longer a headache lasts, the harder it is to stop. Ask your child’s primary care doctor to provide a letter for the school so your child can receive rescue medicine as soon as the migraine starts. A daily medicine to prevent migraines may be helpful. This is true if the migraines happen once a week or more, last several days, interfere with school attendance or performance, or cause neurological problems. Your child’s doctor will consider how often the headaches happen. The doctor will discuss with you the medicine’s possible benefit and side effects. You can use non-medication or complimentary treatments with medicine. These may help treat or minimize the migraines. These include relaxation training, massage, physical therapy, biofeedback, self-hypnosis, and imagery therapy.
