All I know is that if he is out for 3 min's he has already lost some brain power (is what I will call it) but I am 15 and I know if he falls down and hit's his head in the front that could make his migrans worse if he falls and hits eaither his left or right side he could lose memory,and could be peralized for a short time but if you'r drs say he is fine they must have something up their butt's or they need to go back to school my oppinion is find a new dr. and if you can't cuz of insurence then try and get a new dr. at the same place if not I would go to the hospital. If it happens again you should call 911 I hope that I have helped you and I am very sorry about your problems. With all my hopes Michelle
