description: A neonatal/infantile epilepsy syndrome characterized by the onset of non-self-limiting seizures and developmental regression or delay in infants/neonates. This condition is typically caused by genetic mutations that disrupt normal brain development, affecting both cognitive and motor development that is not responsive to typical seizure treatments.
