question: Hi doctor, Before 5 years, I fell down backwards on the ground. My head collided strongly. Now, I am having some ill feeling in head and that is not a headache. Once, while sleeping on the floor, I became unconscious for a while. My EEG result says that I have a seizure. What is it? Shall I do further tests like scanning? I attacked my wife while sleeping without my conscious. Please advise.
