Many people wonder why autism statistics have changed over the last 15 years. When I started working with children with autism every 1 in 10,000 children were being diagnosed. Also back then there was not many different names and it was not know as so much as a spectrum disorder.
Now, 1 in 150 children are being diagnosed and it is 1 in 94 boys. We all wonder why. Is it environmental factors, genetics of some sort, possibly vaccinations have something to do with it, or is it that since the 1990's it has had its own disorder classification and people are more aware.
Autism is the second most common developmental disability right after mental retardation. One day I hope as well I am sure you hope too that there will be a definitive answer on what causes this disability. Autism seems to be a hot topic in the government, so at least lets hope that early intervention services will be more affordable to families and give the cildren a better chance to a better life.
