The idea behind ADD/ADHD and why stimulants work is that they speed up the brain, and even ADD/ADHD is a result of a slow brain. Not sure if that is based in science though.

All people within one diagnosis will never report the same thing. Like, I don't misplace things. I do pay attention to details. I do pay attention to the one I'm talking to. But I have other issues that are from ADD.

I'm not really sure SCT exists outside ADD/ADHD or part of it.
