The electroencephalogram in pediatric practice: its use and abuse.

Utilized appropriately, the EEG is a helpful diagnostic tool; however, it is currently much abused and much overutilized. Understanding its limitations and its usefulness may lead to less frequent but more appropriate requests for EEGs. Realization that the EEG alone neither diagnoses nor rules out epilepsy and that it is not crucial in the diagnosis or management of "minimal brain damage" should decrease the utilization and abuse of the procedure.
