Prevalence and Incidence of Trigeminal neuralgia
Trigeminal neuralgia: Rare Disease
Trigeminal neuralgia is listed as a "rare disease" by the Office of
Rare Diseases (ORD) of the National Institutes of Health
(NIH). This means that Trigeminal neuralgia, or a subtype of Trigeminal neuralgia,
affects less than 200,000 people in the US population.

Trigeminal neuralgia:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
Although the cause remains undetermined, trigeminal neuralgia may reflect an afferent reflex in the brain stem or in the sensory root of the trigeminal nerve. Such neuralgia may also be related to compression of the nerve root by posterior fossa tumors, middle fossa tumors, or vascular lesions (subclinical aneurysm), although such lesions usually produce simultaneous loss of sensation. Occasionally, trigeminal neuralgia is a manifestation of multiple sclerosis or herpes zoster. Whatever the cause, the pain of trigeminal neuralgia is probably produced by an interaction or short-circuiting of touch and pain fibers.
Trigeminal neuralgia occurs mostly in people older than age 40, in women more commonly than men, and on the right side of the face more commonly than the left. Incidence is 4 to 5 cases per 100,000 people.

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.

Tics:
Tics - epidemiology
(The 5-Minute Pediatric Consult)
Described in almost all ethnic groups. Affects males > females. Typical onset: Age 5–7 years
Tics - prevalence
The prevalence of chronic tics and TS in school-age children is 3–6% and 0.1–1%, respectively. Transient tics occur in 20–25% of children.

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