It hasn't changed since the 60's. Listening to people who self-diagnose ADHD might give you that impression. Same with Autism, which seems to be every third person if you believe social media over actual doctors. People seem to feel this makes them more interesting. It doesn't, really. It makes them a different kind of statistic. ADHD is more well understood now (which is why it is separated into Compulsive, Hyperactive or both) but the diagnostics, as determined by professionals in psychiatry, have not changed in decades. The biggest change in studies for ADHD is how it affects females differently than males.
