I don't know, I'm thinking doctors and the like have more evidence to support their side of the ADHD/ADD diagnosis than you have to support your argument. I don't disagree that it's likely to be misdiagnosed in many cases.
The difficult thing is finding the root cause. For me, turned out I couldn't absorb food all that much, particularly certain foods like wheat. Aside from making me feel like crap (gluten allergy), it also contributed heavily to my ADD. After 30-odd years of struggling, I got the right diagnoses & my ADD is controllable now. But there can be a variety of causes. I know someone who was in a severe accident & now has all of the same ADD symptoms I did, but with current medical technology, there's just no way they can be cured or even managed because we just don't know how to do that yet.
It's common & funny sometimes for people to say "oh that's just my ADD", but there's a line between having a moment & actually having it to the point where it wrecks your life. For example, my grades growing up were exclusively A's and F's; I didn't really have a choice in terms of what I was interested in, either I was full-on or full-off, effort all the way or nothing. Or being unable to
not procrastinate on things that would ruin your life or cost you a lot of money, time, or effort down the road. Taking up new hobbies or projects full-bore for a few weeks & then abandoning them completely. Hyperfocusing on everything but your actual priorities. Being unable to
not zone-out when talking to someone or reading a page in a book, especially a textbook. Looking like a hoarder because of all of the phases you've gone through.
It's not laziness or a lack of self-control, it's simply that there's a gyroscope in your brain preventing you from living life how you want. If you've ever seen Memento, it's a similar idea...almost like your brain resets & wants to find something new & more entertaining. I am fortunate enough to have nipped the root cause in the bud, which has been life-changing. I still have it a little bit, especially getting overly-focused on things, but I can manage it now. I can keep my room clean...a small thing now, but a mountain in the past. I finished college, with flying colors, after spending more than a decade struggling with it. I have an awesome job. Everything is a million times easier because I can simply decide to buckle down & actually follow through now. And I can harness some of the energy, too, like the hyperfocus thing...I can direct it towards things I want to now.
My wiki & certain forum posts are small examples of how ADD works. My browser at any given time has 6 windows open with 20 tabs each. Researching down endless rabbit holes for hours at a time...at least I started collecting & organizing relevant data so I wouldn't forget things.
Need an A to Z guide on color grading for film? How about some
interesting car links? Why not spend 14 hours straight creating the
best list of home automation junk on the web? Babysitting a
30-page thread on mini computers? Or a
130+ page thread on a more specific home automation widget? But hey, why stop there? Why not make a post on
neat home materials too? Wait, let's go dig up some more car stuff,
specifically on Tesla! And then not update it for 2 years!
But wait, time for a new phase!
Cooking!
Micro-computers! A list of
stuff to do when you're bored, but then you totally forget it exists! Or all of the little projects I start & then stop because I decided to make cookies or watch Youtube for four hours straight or remembered that my bathtub was dirty & needed to be scrubbed out, like an
Android 101 guide or porting over a
photography resource listing. Figured out a dumb trick with my iPhone, why not
make a video about it? Or let's get more specific with computers, like the
HP Mini. Or
Hackintosh. And that's just the
written stuff I've bothered to save in one or two locations. Not a brag post...it's just that ADD does in fact exist. It's fun when you can call the shots, but when you can't, you look back at all of the random crap you've done, zillions of hours spent on inane projects, even more hours spent on unfinished ones, and then forget about all of that & you're off to do something else
