Electrodecremental status epilepticus is classically described in infants and children with severe refractory epilepsy, mental retardation, and structural brain abnormalities. We describe a 24-year-old woman who presented to the emergency department with prolonged tonic status epilepticus which evolved into stimulus-induced diffuse voltage attenuation (SIDVA) pattern in the setting of aseptic meningoencephalitis. There was no history of seizures or further events after recovery. This is the first report of a SIDVA pattern in an adult without a history of epilepsy.
