About prevalence and incidence statistics:

The term 'prevalence' of Adult ADHD usually refers to the estimated population of people who are managing Adult ADHD at any given time. The term 'incidence' of Adult ADHD refers to the annual diagnosis rate, or the number of new cases of Adult ADHD 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.
