Does migraine-related stroke occur in childhood?

This report concerns seven children who had at least one episode of infarct, possibly during an attack of migraine. They fulfilled the following criteria: presence of acute neurological deficit associated with headache or other symptoms characteristic of migraine attacks; a history of migraine; evidence of infarct on CT scan; and no other evident cause of the stroke. CT showed that the area of infarction was in the distribution of the posterior cerebral artery in three cases. Four of the children have been followed for at least 23 months and none has severe residual deficit. An aetiological relationship between migraine and stroke could not be demonstrated. However, epidemiological data suggest that childhood migraine can be a contributory risk-factor for strokes.
