Tic disorders: Causes and incidence
(Professional Guide to Diseases (Eighth Edition))

Although their exact cause is unknown, tic disorders occur more in certain families, suggesting a genetic cause. Tics commonly develop when a child experiences overwhelming anxiety, usually associated with normal maturation. Tics may be precipitated or exacerbated by the use of phenothiazines or central nervous system stimulants or by head trauma.

All tic disorders are three times more common in boys than in girls. About 2% of the population has Tourette syndrome.

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. For more information see about prevalence and incidence statistics.
