Familial cortical myoclonus
Familial cortical myoclonus is a rare genetic movement disorder characterized by autosomal dominant adult-onset slowly progressive multifocal cortical myoclonus. Patients present somatosensory-evoked brief jerky involuntary movements in the face arms and legs associated in most cases with sustained multiple sudden falls without loss of consciousness. Seizures or other neurological deficits aside from mild cerebellar ataxia late in the course of the illness are absent.
