Female, Hemou, 18 years old. Eldest daughter, full day birth, well-developed, normal during pregnancy, no history of encephalitis and traumatic brain injury, no family history of epilepsy. His father’s complaint: patients 13 years of age there was no obvious incentive paroxysmal laughter with extremities twitching.

Physical examination and laboratory tests showed no abnormalities. Nervous system examination without location signs. Electroencephalogram: basic wave rate to the long short distance low amplitude 9 ~ 12c / sα wave rhythm, the amplitude adjustment is poor, the waveform irregular, tracing seizures occurred in the process of a time, when EEG showed long and short range high Apex amplitude (spine)
