Nope you’re wrong. And tons of people have it. They way they can tell is they treat it and the problems go away.
Virtually everyone focuses better on the right level of stimulant—which is ADHD treatment.
Used to be that professional baseball players routinely took ‘greenies’ to improve performance. And, of course, there’s a massive black market for ADHD drugs in college, as a general aid to studying.
At what cost? Lots of symptoms 'go away' with medication. There are always side effects of one degree or another.
That means nothing. German fighter pilots during WWII were given drugs that improved their stamina and concentration, but that didn’t mean they had a problem.
Anyway, the point is not that there aren’t a group of behaviors and “symptoms” associated with so-called ADHD, but that they’re a function of bad parenting. And they are.
Are you talking about giving them drugs? If so, I'm not convinced.
