Autism

<p>I wasn't sure where this should go.....but</p>

<p>There isn't a defined cause for Autism yet, right? I know that the prevalent theory is genetics, but then there's also the testosterone one and a few others.....</p>

<p>I've tried looking this up on the internet, but there are so many conflicting answers. Does anyone know where i can find out for sure?</p>

<p>Well, I think the thimerosal controversy can tell you pretty conclusively that there isn't a defined cause... because if there were a defined cause, it wouldn't be a controversy anymore.</p>

<p>Okay, just checking....thanks</p>
