What can be the cause of a child having periodic fainting spells usually once he has fallen down or gotten hurt from a typical child accident in which he may barely get hurt. He has had this on and off I think she said around 8 times and he is now 6. The first occasion was when he was 15 months old. They have ruled out seizures; so what can be causing this? I believe on a couple of occasions, it wasn't just prior to a fall or scrape. He has been seen by his pediatrician and a holistic doctor as well as had necessary tests to rule out seizures.
