Well I only know that because I skipped to the end. Then, while scrolling up I realised I missed the whole side-quest about promising to not cheat the test again, taking the test again, but then "accidentally" finding an exploit the system, and then cheating the test again, but this time cheating even more to see the results.
Then, scrolling up more I see that this whole thing started with seeing stars and then buying a telescope on amazon (probably at 3am).
And here I am commenting on HN instead of replying to an email...
The other thing is, ADHD in my mind is really a syndrome that starts with a symptom - inattention - that can be caused by so, so many things.
I have both, because of course I do, I had a medical problem that exacerbated my ADHD to a significant, significant degree (it's amazing I was able to be a software engineer for so long without treatment). So don't just tunnel vision in... as we tend to be prone to do. Get the whole workup with an experienced clinician, it's so lifechanging it's hard to describe.
You wrote "the test is quick, easy, and painless" but I also want to note that it's not always. Depending on your country, parents, specific doctor, etc it can be very difficult to get a proper diagnosis and help. In some places a big criteria is diagnosis during childhood so if you're 30 or 40 you might have no chance. Or a chance but it depends on your parents retroactively answering a questionnaire, or finding an old report card with the right words.
As you said it's life changing to get the right help and I encourage everyone to pursue this.
Btw no criticism implied on my end, I'm just now constitutionally incapable of not telling people they should get screened. Hmmm I wonder why I have difficulty resisting that urge...
The chance to be diagnosed with an appropriate gate varies greatly based on where you live and which doctor you can see and more. It can be anything from a 5 minute conversation, to 6 months of inconvenience, to no chance of even existing in your lifetime, to suck it up and don't ask because your career will end.
Huh? You don't have to be tested as-a-child, you don't have to call up your fourth grade teacher. You can self report your subjective experience.
"Did you have these problems as a child? Have you always had trouble doing your homework? Did stressing out about homework enable you to do the homework?"
They ask the question a few different ways typically.
I get it, perhaps it is different in your area, but I get the impression that an adult ADHD diagnosis is far from impossible.
In the US, at least, it ranges from difficult to straightforward, but that's not true everywhere
It turns out, there are other conditions out there that can appear to be be ADHD. If a trained therapist can confuse them, outside observers certainly can too, so it is possible that "very ADHD-acting" person you know might not have it.
(Or, especially for females, the reverse can be true, as not everyone with ADHD manifests with the same trademark hyperactivity.)
Executive dysfunction, especially that which was not impairing as a child, has a lot of potential causes. Anxiety, depression (yes, ADHD can cause these, but these can also cause executive dysfunction in people without ADHD), OCD, Bipolar (manic people in particular often attribute worsening of hyperactivity and distractability to ADHD instead of mania), Schizophrenia pretty much universally is related to cognitive symptoms and lowered motivation even when not psychotic, and borderline personality disorder can cause changes in interests and identity.
For many of these conditions, stimulants can act as a band aid on something else. It can superficially make people feel better (of course, it's speed), but it can distract from other symptoms that are impairing functioning, and prevent people from seeking long term solutions.
I recognize that non-medical options should always be front line approaches but there can be a chicken and egg effect as to making that happen.
In my youth I adhered to a "better living through chemistry (wink wink)", I do now too (rip Mitch Hedburg) but the wink wink part is very rare and disciplined and now it's all about pharma and supplements to wring what I can out of what I've got left.
That's not to say I'm not on the medication train (despite moaning about medications a lot). I do personally avoid taking any controlled substances. This is easy because I hate how stimulants make me feel, but in general I worry about the effects of having a direct reward signal from taking a pill.
