For a seriously autistic kid, the best prognosis might be getting into a mainstream school without being too much of a shadow. For a moderately autistic kid the best prognosis is full recovery.
Parents of recovered children, and I've met hundreds, all share the same experience of doubters and deniers telling us our child must have never even had autism or that the recovery was simply nature's course. We all know better, and frankly we're too busy helping other parents to really care.
Corner one of the hundreds of doctors who specialize in autism recovery, and they'll tell you stories of dozens of kids in their practice who no longer have autism. Ask them to speak to the press and they'll run for the door. They know better.
When I first went public with my son Evan's story, I just planned to talk about the 'R' word - Recovery. But soon I was spending most my time talking about the 'V' word - vaccines.
