Periodic electroencephalogram discharges in a case of Lafora body disease: An unusual finding

Abstract

Lafora body disease (LBD) is a form of progressive myoclonic epilepsy, characterized by seizures, myoclonic jerks, cognitive decline, ataxia, and intracellular polyglucosan inclusion bodies (Lafora bodies) in the neurons, heart, skeletal muscle, liver, and sweat gland duct cells. Electroencephalogram (EEG) findings in LBD may include multiple spikes and wave discharges, photosensitivity, multifocal epileptiform discharges, and progressive slowing in background activity. Periodicity in epileptiform discharges has not been frequently depicted in LBD. We herein report an unusual case of LBD who showed generalized periodic epileptiform discharges in EEG.

“…Other clinical signs that occur less frequently include ataxia, poor vision/blindness, deafness, dementia, aggression toward people or other dogs, urinary or fecal incontinence, jaw smacking, and flycatching (12). Pathologically, intracellular polyglucosan inclusion bodies (Lafora bodies) are present in the neurons, heart, skeletal muscles, liver, skin, and sweat glands (13).…”
