Unilateral chronic daily headache occurs in approximately 2% of adult patients, and often represents a trigeminal autonomic cephalalgia. We now describe the characteristics of 23 children who presented with a persistently unilateral chronic daily headache. The clinical features of our patients' headaches were primarily migrainous; however, the diagnosis of a trigeminal autonomic cephalalgia or a secondary headache disorder was frequently made.
