Autism is a hot topic, lets face it, the increase in prevalence has started to cause a panic in some people. That fear is what the anti-vaccination movement is hoping to capitalize on, but that doesn’t stop science from trying to solve what is really causing the problem. There are probably several roads to autism, most — if not all — of them genetic. Scientists have already found one definite genetic cause of autism and several genetic factors. Now it looks like they may have even found the actual brain changes that cause it. With these new discoveries come better testing, treatment and more individualized care.
