Electrographic seizures: Pattern has to last at least 10 min in patients with qualitative or quantitative impairment of consciousness. The following criteria qualify: (1) epileptiform discharges at >2.5 per second or (2) improvement after treatment with typical ictal spatiotemporal evolution or subtle ictal clinical phenomena with epileptiform discharges/rhythmic activity >0.5 per second. |
