16 million Americans seems to correlate fairly well with the medical consensus that around 5% of adults have some degree of ADHD. Perhaps it's not as widely over-diagnosed as sometimes claimed? " But to suggest there's some biochemical reason for this that's cured by amphetamines seems like pseudoscience to me." A pseudo science that very strongly runs in families. A pseudo science that's strongly linked with dopamine transmission. A pseudo science that has some medical evidence pointing to it being an under development of the frontal lobes. I suggest you google the field a little.
