I'm sorry for this rude person but are there, or why, so any Americans with adhd. I don't know anyone having it here and I meet a lot of Hackers... The population should be similar. Here it feels like everyone has it or knows about it.
In my experience in other countries, the primary difficulty for ADHD support groups is that many country's medical institutions do not even acknowledge ADHD as a thing.
Some of these institutions acknowledge, but seem to believe that the condition disappears when you turn 18.
Many of the regulatory institutions don't allow stimulants to be used for treatment, either.
This is mostly an anti-scientific position. ADHD is extremely well-researched. Its (medication-based, not CBT) treatment is the most effective of any mental illness, more so than "understood" things like depression.
I'm biased, but I think a lot of places are still in denial about ADHD. There's way too much research around the illness and its effects and treatment.
It was just, "oh, his GPA's low? Seems like he can't focus? Here are some amphetamines, have a nice day!", with zero follow up about whether the medication was doing its job (didn't matter -- I never took it anyway).
