Abstract
Epilepsy is one of the most common neurological disorders to affect children, and has its highest incidence in infancy. Approximately one-quarter of children have seizures which are drug-resistant, and place the child at increased risk of cognitive delays, attention, behavior and psychiatric disorders, injury, sudden unexpected death and poor quality of life. This article presents a rational approach to the investigation and management of children with drug-resistant epilepsy.
