Is There a Cause for Autism?

In a year I was like, I'm sure this happened to people who were autistic, right? Oh, God. And they didn't even know, was autism even diagnosed in the 70s? No. It's possible that's what was going on with Rosemary. She may have had like Asperger's or something like that. But being like, oh, a few percentage of people, this really small group, this really helps doesn't mean we should be doing it for everyone. Those numbers don't really match up if 95% of the people are benefited from me.
