We think our son, who has Down syndrome & autism, fainted a few days ago. We had gotten up early Friday morning, didn t get to eat b fast, and headed an hour away to take a raft down the French broad river. This was approximately 31/2- 4 hours. Finished, then went to eat. Our son walked up to my husband and put his arms around his dad s neck. I was standing beside them. All of a sudden, our son started to fall back. First we thought he was pulling us down on purpose, then we both saw a blank look in his eyes and he fell back, hitting back of head on hard floor. He just looked blank . Lasted 30 seconds or less. No shaking, foaming at mouth, no eyes rolling back on head, etc. I first thought he was having a seizure( which he has never had, either). He came to is sitting up, a bit agitated( like he sometimes can be). He ate & drank after that. Did he faint, seizure, or something else? I plan on contacting his pediatrician, too. This has never happened!
