Now it's Schizophrenia. The bad thing about research is for every 'study' that supports one set of views, there are three others that support an opposite conclusion. Autism? It's the water, bad parenting, vaccinations, genetics, heavy metals, pollution, preservatives, etc.. etc., etc...
As the Dad of six children with Autism I'm more concerned with research that can help the Autistic person to have a more full life. Research to uncover the best in education, social training, nutrition and treatments. Some funding spent on 'why' is acceptable, but the bulk needs to be addressing the here and now and plan for the future.
Funding for Autism research is good, funding to help with day to day living, is better.
Autism is a spectrum disorder, caused by a spectrum of reasons, needing a spectrum of treatments and a spectrum of funding. (Spectrum: A broad sequence or range of related qualities, ideas, or activities).
Our country must get moving to discover what can be done improve this situation. If every parent of Autism will be an advocate we can make a HUGE difference for our children. So make calls, write, search and read. Do what you can when you can. We are all in this together and we need each one of us.
