See Neurologist: Sounds like your son had a seizure. It also sounds like he had a lot of tests, some not done in emergency room (EEG, sleep study). The doctor who tested him or a neurologist in your area should discuss the findings and help you decide what is wrong and what to do. Sometimes tests reported "normal" can tell us things. To find a neurologist, call your local hospital or medical society.
