Trigeminal neuralgia (TN) and multiple sclerosis (MS)
According to the American Association of Neurological Surgeons (AANS) trigeminal neuralgia is now known as an early symptom of multiple sclerosis, the autoimmune disease of the central nervous system. In fact, AANS states that MS is “usually the cause” of trigeminal nerve pain in young adults.
Studies show that an estimated five percent of patients with trigeminal neuralgia also have multiple sclerosis, and about two percent of people who suffer from multiple sclerosis will go on to develop trigeminal nerve pain.
Research also shows that people with multiple sclerosis are about 20 times more likely to develop trigeminal neuralgia than those who do not have MS. Patients with both the nerve pain and multiple sclerosis tend to be younger than those without MS. Whether you have multiple sclerosis or not, trigeminal neuralgia seems to impact both sides of the face; however, it is more common on both sides in people with MS.
Clearly trigeminal neuralgia causes are different depending on whether or not you have multiple sclerosis.
