National Institutes of Health Ramsay Hunt syndrome type II, also called dyssynergia cerebellaris myoclonica, is a rare, degenerative, neurological disorder characterized by epilepsy, cognitive impairment, myoclonus, and progressive ataxia. Symptoms include seizures, tremor, and reduced muscle coordination. Onset of the disorder generally occurs in early adulthood. Tremor may begin in one extremity and later spread to involve the entire voluntary muscular system.
Arms are usually more affected than legs.
Treatment of Ramsay Hunt type II is symptomatic. Myoclonus and seizures may be treated with the drug valproate. This information is not intended to be a substitute for professional medical advice.
