Classic TN as advertised by the TNA
Classic Trigeminal Neuralgia, type 1, (TN1): (also known as tic douloureux) facial pain of spontaneous onset with greater than 50% limited to the duration of an episode of pain (temporary pain). TN is often caused by loss of or damage to the nerve’s protective coating, (myelin). The most widely accepted view is that myelin damage results from irritation of the nerve, usually a blood vessel that causes the nerve to be compressed.
