Autism is a serious developmental disorder, i was diagnosed whit it when i was a baby, by mistake of course
That's quite a relief. My coworker has a child with autism, but I don't really know much about it.
Its probably really hard for him, too bad autism is characterized by troubles with social interaction and communication, its a difficult condition
There's some hope though as it can be treated with behavioral therapy and/or meds.
Yes, it can help a lot, there are a lot of controversies surrounding autism  for example the vaccine hypotheses, which have been disproven.
