Migraines are a severe type headache that involves blood vessels, nerves, and brain chemicals. It recurs often. Auras are sensations that come before a migraine occurs. One type of migraine has no aura before it starts. The other type comes with an aura. Auras often include visual changes, or numbness and tingling.
Migraines can affect a child’s performance in school. It can also effect relationships with friends and family. Medicine should be started as soon as symptoms appear. This will lessen the length of the migraine. Early treatment can also reduce the time with symptoms.

The Migraine Headache
Migraine pain starts within an hour of the aura ending. Symptoms include:
A headache (usually on one side but may involve both sides) that may be:
- Moderate or severe in intensity
- Throbbing or pulsating
- More severe with movement
- Nausea or vomiting
- Sensitivity to light or sound
A Post-Headache Period
Migraines typically last from 4 to 72 hours. They often go away with sleep. After the headache, your child may experience:
- Trouble concentrating
- Sore muscles
- Mood changes
You will be asked about your child’s symptoms and health history. A physical exam will be done. Your child will also be given an exam of the nervous system. The diagnosis is usually based on your child's symptoms.
Imaging tests may be done if your child's symptoms are severe. The doctor may also want to rule out other conditions. Image tests may include:
- CT scan
- MRI scan
The goal of treatment is to:
- Treat headaches early
- Reduce headache duration, severity, and frequency
- Restore the child’s ability to function
- Improve the child’s quality of life
Treatment includes a combination of therapies which may include:
Medicine is the first treatment option for migraines. The type of medicine will depend on how severe the headaches are. Your child’s response will also be tracked.
- Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen
- Triptans to constrict blood vessels and block inflammation—may depend on the child's age
- Dopamine receptor blockers
- Antiseizure medications
- Magnesium sulfate
Most medicine will be taken by mouth. It may need to be given through IV for severe migraines. An IV may also help if there is vomiting.
Therapy can promote relaxation. It may also improve the ability to cope with pain. Either way it has been shown to reduce the how often migraines occur and how long they last. It may be used with or without migraine medicine. Therapy options include:
- Cognitive behavioral therapy
- Relaxation methods.
