Summary
Excerpted from the GeneReview:Autosomal dominant sleep-related hypermotor (hyperkinetic) epilepsy (ADSHE) is a seizure disorder characterized by clusters of nocturnal motor seizures that are often stereotyped and brief (<2 minutes). They vary from simple arousals from sleep to dramatic, often hyperkinetic events with tonic or dystonic features. Affected individuals may experience an aura. Retained awareness during seizures is common. A minority of individuals experience daytime seizures. Age of onset ranges from infancy to adulthood. About 80% of individuals develop ADSHE in the first two decades of life; mean age of onset is ten years. Clinical neurologic examination is normal and intellect is usually preserved, but reduced intellect, psychiatric comorbidities, or cognitive deficits may occur. Within a family, the manifestations of the disorder may vary considerably. ADSHE is lifelong but not progressive. As an individual reaches middle age, seizures may become milder and less frequent.
