Familial Adult Myoclonic Epilepsy

Tremor and myoclonus in familial adult myoclonic epilepsy are shown in a family from New Zealand and Australia. Video segments of 13 representative affected subjects are presented in approximately ascending order of severity. Distal hand tremors are evident in all cases and minimyoclonic finger and hand movements are seen in most cases. In addition, the video segments demonstrate more proximal upper limb myoclonus and tremulous and myoclonic movements of other body parts (eyelids, legs, and feet).
