Definition

Migraine is a type of recurring headache that involves blood vessels, nerves, and brain chemicals. Sensations called auras may come before a migraine. Auras can include visual changes or numbness and tingling. There are two types of migraines:

  • Temporary partial loss of vision
  • Speech difficulties
  • Weakness in an arm or leg
  • Numbness or tingling in the face and hands

  • Diagnosis

    The doctor will ask about your child’s symptoms and medical history. A physical exam will be done. Your child may also be given a neurological exam. The diagnosis is often based on your child's symptoms. To rule out other complications, your doctor may order imaging tests such as:
