I'd personally recommend to go get checked. The evaluation I went through was like 6 hours long (I know, getting checked for ADHD and they want 6 hours of testing?! Seriously.) But it is to rule out other issues, other conditions and to ensure that the results are correct. In fact, they even adjust for "faking it" in the tests (not that someone couldn't do it, but they are looking for common patterns that would indicate someone try to sway the tests).

I'm definitely not, as you put it, the stereotypical "hyperactive", but on learning more, I realized how many little tics I have that I do but in very masked ways so as to not draw attention. But that aside, there is 3 different diagnosis for ADHD - primary hyperactive, primary-inattentive or combination (both to some level). Despite what I said about tics, my diagnosis was for the inattentive side of things. "Head in the clouds", "daydreamer", etc.

It's all relatively new for me, it wasn't something I really seriously considered until a year or two ago (and I'm in my 40s now), despite having a brother who was medicated fairly young and a father who displays many of the same traits (never diagnosed though). It's definitely helped me to know this, puts some puzzle pieces in place, so to speak, and gives me a path forward toward managing something I didn't really realize I needed to manage, but was having a significant impact on my life regardless.

Nice to know they were that comprehensive. I'm definitely considering checking down here in my area one with good reputation.

BTW, when you talk about tics, do you mean physical tics, like fidgeting, walking around, moving your feet, etc? Because it's quite often noticed by others that I'm doing too much of that

Yup - while I don't present as Hyperactive, it turns out that those little tics are a symptom and I never really realized it until it was pointed out. And now I can't really stop noticing it when I'm doing different ones. But also, some of that may be not just awareness, but a level of acceptance that allows me to stop masking them (i.e. noticing I'm doing it and stopping to please others or hide it, probably goes back to school when told to stop fidgeting).
