  • Trigeminal neuralgia

    Trigeminal neuralgia is a sudden, severe facial pain, described as sharp, shooting or like an electric shock.It usually occurs in sudden short attacks lasting from a few seconds to about two minutes, which stop just as abruptly. In the vast majority of cases it affects part or all of one side of the face, with the pain most commonly felt in the lower part of the face. Very occasionally it affects both sides of the face, but not normally at the same time. Neuropathic pain is the cardinal sign of injury to the small unmyelinated and thinly myelinated primary afferent fibers that subserve nociception. The pain mechanisms themselves are altered. Microanatomic small and large fiber damage in the nerve, essentially demyelination, commonly observed at its root entry zone (REZ), leads to ephaptic transmission, in which action potentials jump from one fiber to another.A lack of inhibitory inputs from large myelinated nerve fibers plays a role. Trigeminal neuralgia is treated on an outpatient basis, unless neurosurgical intervention is required. Management of this condition must be tailored individually, based on the patient's age and general condition. In the case of symptomatic trigeminal neuralgia, adequate treatment is that of its cause, the details of which are out of the scope of this article. Mexico people around 489,378 among the total population are suffering from this disease that is 2.18% of the population effected.
