title: The value of EEG in children with chronic headaches.
abstract: To establish the usefulness of electroencephalography (EEG) as a diagnostic tool in the evaluation of headaches in children, we retrospectively reviewed the records of all children referred to our outpatient neuropediatric clinic because of recurrent headaches. Of 312 children, 257 (82%) underwent EEG tracings: 143 of the children who had had EEG recordings were diagnosed as migraineurs. In 31 (12%) of the children, the EEG revealed epileptic activity. The highest incidence of epileptic EEG activity was found amongst the children with very brief headaches. In 22 (8.6%) of the children, diffuse or focal slowing was detected. The group with migraine headache had a significantly higher incidence of slowing than the group with other types of headaches. There was no correlation between focal EEG abnormalities and brain radioimaging studies or clinical course. We conclude that despite the high incidence of epileptic abnormalities, the contribution of EEG to diagnosis and treatment in children with chronic headache is minimal, and should not be routinely prescribed in these children.
