Trigeminal Neuralgia, also known as Tic douloureux, is a chronic neuropathic pain associated with the fi h cranial nerve (Trigeminal nerve) which carries sensations from the face to brain and some of the motor functions like bi ng and chewing. The aim of this review paper was to determine the current aspects about trigeminal neuralgia including its classification, etiology, diagnosis, and treatment options. The review was conducted using previous research, review, and case studies. The average onset for trigeminal neuralgia is between 50-70 years, although can be found in younger age too. A complete and thorough history is the most important diagnosis tool as well as for prognosis of the disease. Though vascular compression induced morphologic changes in the nerve being the most common cause of trigeminal neuralgia, other variants of its clinical phenotype and etiological factors must also be considered. New MRI methods have helped in proper diagnosis, providing insight about the TN pathogenesis and prognosis. Various new drugs have promising results though more larger scale studies are required. Microvascular decompression is the major and widely accepted method for long lasting pain relief in trigeminal neuralgia
