Epileptic Encephalopathy with Continuous Spike-and-Wave During Sleep (EE-CSWS) is a rare pediatric epilepsy that impacts more than 6,000 children in the United States. Typical onset occurs between ages 2 and 4 years old with seizures occurring infrequently. Diagnosis of EE-CSWS is based on a unique electroencephalographic (EEG) pattern for electrical status epilepticus in sleep (ESES), together with cognitive stagnation and regression. There is currently no approved treatment for the disorder.
