I don't know if it's only the Baader–Meinhof phenomenon or a real impression but for the past few weeks I've seen a lot of testimony and articles on ADHD (on hn and other media). Some friends also started to mention it more than before. I always recognize myself in those testimony and I think it's time to do something about it. So thank you for your message!
My theory is that it is a general increase of awareness around both ADHD and autism (and some other neuro-divergencies) in mainstream media. Fueled by the pandemic/lockdown situation which seems to have surfaced a lot of pre-existing ND problems for many people.
I'm in Europe and before COVID, going to a therapist was often viewed as only necessary for trauma. During and post-COVID everyone and their dog is seeing a therapist for focus/burnout/anxiety/motivation issues. Which could lead to an increase in diagnoses, which in turn leads to more people talking about it. Feed that into the Twitter/TikTok/Insta feedback-loop combined with the media jumping on it and we get the current situation.
It's either that or the vaccines do cause autism... /s
