Abstract
The causes of chronic, recurrent headaches, the electroencephalographic findings and the response to phenytoin (Dilantin) and other medications have been evaluated in 100 children. A history of head injury was reported in 41% and convulsions had occurred in 15%. Electroencephalographic dysrhythmias were severe in 18 and moderate in 27%. Migraine was diagnosed in 42% and tension headaches in 18%; psychogenic factors complicated learning disabilities and minimal brain dysfunction in 21%. Phenytoin controlled migraine in 77% and headaches diagnosed as seizure equivalents in 40%; the response was unrelated to the degree of electroencephalographic abnormality. An abnormal electroencephalogram and response to phenytoin are insufficient criteria for a diagnosis of epilepsy in children with recurrent headaches.
