&gt; The late 90s and early 2000s are exactly when ADHD first started being diagnosed

Nah, it was even earlier than that.  I was diagnosed and medicated back in '92, and my oldest brother was diagnosed in the late 80s (probably started being medicated around then too, but not sure).  Late 90s is when it started to become normalized.

Yes, that’s what I meant, apologies for being unclear in my language (and thanks for the correction).. ADHD diagnoses had been a thing for quite a while, but the late 90s was when it became common enough that a critical mass of people were aware of it and it entered into “pop culture” consciousness.
