the debatable causes of autism..

For my research topic I wanted to choose something that could be of future use to me. So I decided to write about the theories associated with the causes autism. I find autism to be extremely interesting, mainly because these are the kids I want to teach after I'm done with school. There are a ton of speculated theories that explain what autism is, what triggers it, and how to treat it. I'm not sure what theories I believe and disagree with because I haven't put much thought or research into it yet. This topic is something I need to be more aware of so why not start now?
