In 1968, Penman reported the US prevalence of trigeminal neuralgia (TN) as approximately 107 men and 200 women per 1 million people. [10] By 1993, Mauskop noted approximately 40,000 patients have this condition at any particular time, [11] with an incidence of 4-5 cases per 100,000. More recent estimates suggest the prevalence is approximately 1.5 cases per 10,000 population, with an incidence of approximately 15,000 cases per year.

Rushton and Olafson reported that approximately 1% of patients with multiple sclerosis (MS) develop trigeminal neuralgia, [12] whereas Jensen et al noted that 2% of patients with trigeminal neuralgia have multiple sclerosis. [13] Patients with both conditions often have bilateral trigeminal neuralgia.
