Figure 1

Polygraphic recording in a 31-year-old male with GOSR2-associated PME. Left panel: the patient is at rest. The tracing shows slowing of background activity, bursts of generalized spike-and-wave discharges, and multifocal spikes in both hemispheres. Myoclonic potentials are not evident in the EMG leads. Right panel: photic stimulation at 15 Hz elicits generalized polyspikes and spike-and-wave discharges, often associated with myoclonic potentials at both EMG leads. EMG1: right deltoid; EMG2: left deltoid.
