Major mental disorders include: autism, ADHD, major depression, mania, bipolar, schizophrenia, OCD, anxiety, panic,....
Prevalence rate of ADHD is 5-7% in the USA and 8-12% in China.I believe the high rate in China explains (1) why there are so many high intellegent people in China (2) why there are so many internet addicted adolescents in China.
There are two kinds of outcomes for ADHD -- winners (minority) or losers (majority).
ADHD is a real and impairing disorder. It is often under-diagnosed in China.
I sincerely appeal that we all do our best to help those people back in our motherland.
