If everyone relates to some ADHD symptoms, how do doctors actually tell real ADHD apart?

honestly took me getting assessed to realize how much I'd normalized stuff that was actually a problem, not just relatable-meme-level stuff. the assessment asks things like 'has this caused you to lose a job or relationship' which sounds dramatic until you realize yeah, actually, it has, multiple times. that's a different category than forgetting where you put your phone.

tracked this for myself before getting assessed because I had the same doubt — kept a log for about six weeks of every time I noticed something 'symptom-like' and rated how much it actually disrupted my day, not just whether it happened. that distinction ended up being the whole answer. everyone loses their keys sometimes. the question clinicians actually care about is frequency + severity + whether it's causing real impairment across more than one area of your life (work, relationships, home, whatever), not whether the symptom exists at all in isolation. my assessment covered stuff like: full childhood history (were there signs before age 12, even if undiagnosed then), collateral info from someone who knew me as a kid if possible, standardized rating scales compared against population norms not just vibes, and a differential to rule out anxiety/depression/sleep issues mimicking similar symptoms since those are common false positives. what I found genuinely different about my case vs my sister who 'relates to everything online': she loses her keys occasionally and it's mildly annoying. I lose track of tasks so consistently it's cost me actual money — late fees, missed deadlines, a job warning once — across basically every domain of my life for as long as I can remember, not just when I'm busy or tired. that's the impairment threshold. severity and pervasiveness, not the presence of the symptom. quizzes online can't measure impairment relative to your own baseline the way a structured clinical interview can, that's really the core gap between 'relatable' and 'diagnosable.'
