About prevalence and incidence statistics:
The term 'prevalence' of Tourette Syndrome usually refers to the estimated population
of people who are managing Tourette Syndrome at any given time.
The term 'incidence' of Tourette Syndrome refers to the annual diagnosis rate,
or the number of new cases of Tourette Syndrome 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.
