The reason for this "fad" is straightforward — there are a lot of middle-aged humans who are undiagnosed because ADHD was effectively "not a thing" when GenX were kids.

Great! People of all ages should advocate for themselves and pursue health care that might improve their quality of life.
It’s almost like we haven’t collectively created a society that aims to increase human flourishing and instead of created a living nightmare with the illusion of progress due to shiny new technologies.
My opinions on the matter, as someone with ADHD, is that I do not personally believe that treatments that can improve one's life should be gatekeeped (gatekept?) sheerly by disorders. In other words, if people have symptoms and medicine has the tools to treat said symptoms, then such tools should be used regardless of the condition. If one is struggling to achieve a life that is within their potential, then why should they be denied something that can assist them? It would be like saying, "only paraplegic people are allowed to use wheelchairs. It doesn't matter if your legs are broken, they still technically work, thus you don't deserve to use a wheelchair." It's not like various psychostimulants commonly used for ADHD weren't used for 70+ years prior to being indicated for ADHD and other conditions.
Personally, I have always hated the false dichotomy of either one having ADHD or not. I do not think it's that simple, and it is surely not a binary condition. The condition is nothing more than a label assigned to an arbitrary set of symptoms. Even the diagnostic criteria is not all encompassing of the many symptoms people with the condition struggle with.
Just thinking about the various people I know in my life, I would confidently say not all them have equal attention spans, executive functioning, etc.. So, what's the arbitrary cut-off?
Another issue that ADHD (and many other conditions) is that there is absolutely no way beyond a reasonable doubt to prove who has the condition and who does not. There is not a single biomarker -- no gene test, no urinalysis, no blood marker, no fMRI brain scan, etc. that can be used to definitely diagnose the condition in a clinical setting. The diagnosis is just a professional and clinically informed opinion using heuristics.
How was I diagnosed? I went through a gauntlet of exhausting interviews and somewhat pseudo-scientific psychometrics -- WAIS IV IQ test, Stop/Go test, and plenty of others that I cannot remember the name of. It's about as legitimate as one can hope for currently... or at least a decade ago.
With all the being said, I definitely think it's a completely real condition, I just think we are operating on a model similar to the Plum Pudding Model of the atom -- it's not completely wrong, but definitely not correct -- but it's the best we have at the moment. The question I often ask myself is that, "Is there something actually wrong with me, or is something wrong with the world we live in?" For me personally, this disorder has no negative health affects other than making me completely incompatible with this world. I mean, I'm within in the range of average height for adults males. My height causes me no issues in my life. However, if I were to play in the NBA, it would cause all kinds of issues. Does that mean I would have a height deficit disorder?
One more thing about the medications, people have no idea what they are messing with. Sure, stimulants would help a majority of people be more productive (caffeine/nicotine are common for a reason), but nothing in life is without a cost. They absolutely help me live a life that I would unlikely be able to without them. That doesn't mean they are sunshine and roses. In some ways, I feel like I made a deal with the Devil. I have had many friends with ADHD and many friends without ADHD that lied to get access to the medications too. I've seen these medications help people reach the heavens, and I have seen these medications drag people through utter Hell.
Anyway, sorry if this is all over the place and somewhat pointless. I do have ADHD after all. ;)
