GLUT1 deficiency syndrome (ictal EEG)

Ictal EEG of patient with GLUT1 deficiency syndrome, seizures, and paroxysmal exercise-induced dyskinesia. EEG of patient with GLUT1 deficiency syndrome, who presented with typical absence epilepsy and convulsive status epilepticus at age 2 years, and who later developed paroxysmal exercise-induced dyskinesia at age 6 years. During hyperventilation, this patient had a brief absence with high-voltage 3 Hz generalized spike-wave discharges during 6 seconds on EEG. Time base: 30 mm/seconds, sensitivity (of original recording): 300 mV/cm, high cut: 35.0 Hz, low cut: 0.5 Hz. (Source: Suls et al 2008.
