Well, I don’t recall where I heard it. So it may not be true. That said, I have heard talk that some people think adhd is just another form of autism.
The reality is they really don’t know a lot about what causes any of them. So maybe they are putting them all in the same bucket because for all they know, they could all be caused by the same thing. Dunno. I still bet it has something to do with money. Everything always seems to.
