About statistics:
This page presents a variety of statistics about Post-traumatic stress disorder.
The term 'prevalence' of Post-traumatic stress disorder usually refers to the estimated population
of people who are managing Post-traumatic stress disorder at any given time.
The term 'incidence' of Post-traumatic stress disorder refers to the annual diagnosis rate,
or the number of new cases of Post-traumatic stress 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.
