That was quite likely Dr. Russell Barkley you saw.
Just the first 56 seconds of this video (by one of the foremost researchers) explains 100% of what the problem with adhd is. Symptomatically, adhd isn't even named for what it does to a person. Instead it's named for how it inconveniences others. Gee, thanks! I bet it was the same person who named the speech impediment "lisp". Jerk. 😅
