In the past, you also had a group of children who were born and within a short time, three months – six months, everybody knew something was wrong with that child. And that really fell into the old idea of a "Kanner" autistic. However, as we discussed at the NIDS Board meeting, Dr. Plioplys likes to use the terms "acquired" or "autistic regression." I think we have to look at broadening this into a whole new medical term. But, the fact is that if you have a child who starts off normally – you’ve always heard me say that 12, 15, 18 months of age and Dr. Plioplys can give a good argument that you can take a child who is normal to as young as 6 or 8 months of age – and do not show other signs that we associate as a medical disorder, and go into Autism/PDD, we should start thinking of them as an immune or viral process in this whole idea of either acquired or autistic regression.
