or make sure that you have clean underwear handy for any "leakage" that may occur during seizure. one concussion that i had about 8 years ago, after a car accident, the doctor at the er only asked one question, if i had seen stars after the accident. he said that if i did not see stars there was no way i could have a concussion. the guys in the ambulance that took me, and the other doctor that i saw a day later both said i probably had a concussion.
