About statistics:
This page presents a variety of statistics about Attention Deficit Hyperactivity Disorder.
The term 'prevalence' of Attention Deficit Hyperactivity Disorder usually refers to the estimated population
of people who are managing Attention Deficit Hyperactivity Disorder at any given time.
The term 'incidence' of Attention Deficit Hyperactivity Disorder refers to the annual diagnosis rate,
or the number of new cases of Attention Deficit Hyperactivity Disorder diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
For more information see about prevalence and incidence statistics.
