I'd imagine a lot of that increase has to do with fewer people going diagnosed, rather than more people having ADHD in the first place. People become more aware of the symptoms and realize they can get help, they're less scared of being called crazy, etc. Given how hard it is to tell mental conditions apart (I think I remember reading that somewhere around 40% of psychologists' diagnosis are later changed), there are probably some false diagnosis in there too, where the "true" diagnosis is something else that's less top-of-mind, or that hasn't been discovered yet, or is something other than mental disorder.
