Physical and neurological examinations were normal. A magnetic resonance imaging scan showed slight frontoparietal parasaggital atrophy. The routine EEG showed increased generalized intermittant rhythmic slowing that was excessive for her age. With sleep deprivation, bilateral polyspike-and-wave complexes were seen, which were intermittently accompanied by bilateral myoclonic jerks of the upper extremities.
An EEG of the mother was obtained, which showed increased generalized intermittent rhythmic slowing but no epileptiform potentials, even after sleep deprivation.
