Myoclonic epilepsies in adolescent and adult patients
We review the electroclinical characteristics of the main myoclonic epileptic syndromes occurring in adolescents and adults, excepting the progressive myoclonic epilepsies. In the discussion we include some epilepsies which are not currently classified as generalized, but which develop myoclonic crises such as the myoclonic variant of epilepsy when reading. We emphasize strict criteria for diagnosis of juvenile myoclonic epilepsy and discuss the syndromes related to it. Other myoclonic epilepsies, such as those which may occur in adults with Down’s syndrome and in Alzheimer’s disease, are considered.
