Sounds like you're just defining ADHD to mean whatever you want it to mean. Thankfully we didn't have TikTok to diagnose hyperfocusers like Einstein with a brain disease, or we never would have got general relativity.
“While the estimated 8 million adults in the USA affected by attention-deficit/hyperactivity disorder (ADHD) might find it nearly impossible to sit still in a lecture hall or excruciatingly challenging to focus on writing a term paper, these same individuals might find themselves spending hours at a time composing a new song, tinkering with their car, writing computer code, or watching television (Kessler et al., 2006). The term “hyperfocus” (HF) has been used to characterize this state of heightened, focused attention that individuals with ADHD frequently report (Brown, 2005; Conner, 1994; Ozel-Kizil et al., 2016).”[1]
Anyway, not touching ADHD drugs given how easily I can convince myself 2+ drinks is a fantastic idea. So, TLDR 100% not going here:
What it means is some people are able to potentially improve their lives by recognizing a pattern of behavior and educating themselves about strategies (including medication) that might help.
