Juvenile myoclonic epilepsy (2)

Autosomal dominant sleep-related hypermotor epilepsy

Autosomal dominant sleep-related hypermotor epilepsy is characterized by clusters of nocturnal motor seizures, typically beginning in childhood. Seizures occur almost exclusively from sleep, although some patients may have infrequent daytime seizures. More severe cases may have intellectual disability and psychiatric features. It follows autosomal dominant inheritance with incomplete (70%) penetrance.
