The "other" primary headaches in children and adolescents.

Headache represents one of the most common reasons why children and adolescents are referred to pediatric neurology practices where the most common headache syndromes diagnosed are migraine and its variants, and chronic daily headache. The bulk of recent literature regarding headache in children has focused on these two clinical entities even though large epidemiologic studies have demonstrated that tension-type headache may be two to three times more common in children. Why has so little attention been given to these other disorders? The purpose of this review is to examine the "other" primary headache disorders in children and adolescents.
