Causes
In trigeminal neuralgia, also called tic douloureux, the trigeminal nerve’s function is disrupted. Usually, the problem is contact between a normal blood vessel — in this case, an artery or a vein — and the trigeminal nerve at the base of your brain. This contact puts pressure on the nerve and causes it to malfunction.
Trigeminal neuralgia can occur as a result of aging, or it can be related to multiple sclerosis or a similar disorder that damages the myelin sheath protecting certain nerves. Trigeminal neuralgia can also be caused by a tumor compressing the trigeminal nerve.
Some people may experience trigeminal neuralgia due to a brain lesion or other abnormalities. In other cases, surgical injuries, stroke or facial trauma may be responsible for trigeminal neuralgia.
