Abstract
A 39 year old Jewish male with a 22 year history of progressive myoclonic epilepsy was found to have Gaucher cells in his sternal bone marrow. The diagnosis of Gaucher's disease was confirmed by the demonstration of beta-glucosidase deficiency in fibroblasts. Although neurological involvement is extremely rare in adults with Gaucher's disease, this disease is another lipidosis which should be considered in patients with progressive myoclonic epilepsy.
