ADHD

The idea
ADHD is a neurodevelopmental disorder of inattention, hyperactivity and impulsivity; the CDC estimates nearly twelve percent of US children aged three to seventeen have a current diagnosis.
In practice
Boys diagnosed at thirteen percent and girls at seven, partly because girls' symptoms are more often internal.
Where people slip
The misconception is that rising diagnoses mean rising cases; better awareness and screening likely explain much of it.
