Trigeminal neuralgia - Overview

Alternative Names

Tic douloureux

Definition of Trigeminal neuralgia:

Trigeminal neuralgia is very painful swelling (inflammation) of the nerve (trigeminal nerve) that delivers feeling to the face and "surface" of the eye.

Causes, incidence, and risk factors:

Trigeminal neuralgia causes severe, short-lasting (only a few seconds) facial pain on the side of the affected nerve. The condition usually affects older adults.

Often, no cause can be found. However, areas of brain swelling or abnormal blood vessels (arteriovenous malformations) can cause it.

Painful trigeminal neuralgia attacks may occur after lightly touching areas of the face that are along the fifth skull (cranial) nerve.
