Trigeminal neuralgia

Definition:

Trigeminal neuralgia is an extremely painful inflammation of the largest nerve in the skull (trigeminal nerve).

Alternative Names:

Tic douloureux

Causes, incidence, and risk factors:

Trigeminal neuralgia causes severe lightening-like facial pain on the side of the affected nerve. The condition usually affects older adults. Often, no cause can be found, although areas of brain inflammation or abnormal blood vessels (arteriovenous malformations) can be responsible.

Painful trigeminal neuralgia attacks may occur after lightly touching different skin areas of the face, along the course of the sixth cranial (skull) nerve.
