Migraine can occur without headache in children

Definitions of migraine vary. In 1988, the International Headache Society offered a set of criteria that has been widely quoted since. According to this definition, a person with migraines:

Has had at least five headaches in a lifetime.

Experiences at least two of the following symptoms: one-sided, throbbing pain that's moderate to severe; pain that worsens with activity; sensitivity to light or sound; nausea or vomiting.

Has symptoms lasting from 2 to 72 hours per occurrence.

Sometimes the symptoms of a migraine occur even without headache, making diagnosis all the more challenging. "Older kids tend to have more abdominal symptoms — so much so that they can have vomiting, stomach discomfort and dizziness in the absence of a headache," says Dr. Buchhalter. "These symptoms are more common in kids than adults."

Researchers are still not sure what causes migraines. However, there's strong evidence that the tendency to have migraines is inherited. One study found that 90 percent of children with migraines had a family history of such headaches.
