Trigeminal neuralgia (TN), also called tic douloureux , is a chronic pain condition that affects the trigeminal or 5th cranial nerve, one of the most widely distributed nerves in the head. TN is a form of neuropathic pain (pain associated with nerve injury or nerve lesion.) The intensity of pain can be physically and mentally incapacitating. It has been described as among the most painful conditions known to humankind. TN symptoms begin appearing more frequently over the age of 50, although there have been cases with patients being as young as three years of age. The incidence of new cases is approximately 12 per 100,000 people per year; the disorder is more common in women than in men.Trigeminal neuralgia was first described by physician John Fothergill and treated surgically by John Murray Carnochan, both of whom were graduates of the University of Edinburgh Medical School. The trigeminal nerve is a paired cranial nerve that has three major branches: the ophthalmic nerve (V 1 ), the maxillary nerve (V 2 ), and the mandibular nerve (V 3 ). One, two, or all three branches of the nerve may be affected. 10–12% of cases occur on both sides of the face. Trigeminal neuralgia most commonly involves the middle branch (the maxillary nerve or V 2 ) and lower branch (mandibular nerve or V 3 ) of the trigeminal nerve, [6] but the pain may be felt in the ear, eye, lips, nose, scalp, forehead, cheeks, teeth, or jaw and side of the face. TN is not easily controlled but can be managed with a variety of treatment options. TN is typified by attacks that stop for a period of time and then return, but the condition can be progressive. The attacks often worsen over time, with fewer and shorter pain-free periods before they recur. Eventually, the pain-free intervals disappear and medication to control the pain becomes less effective. The disorder is not fatal, but can be debilitating. Due to the intensity of the pain, some individuals may avoid daily activities or social contacts because they fear an impending attack. TN is a progressive disorder that often becomes resistant to medication over time, individuals often seek surgical treatment

Trigeminal neuralgia (TN), also called tic douloureux, is a chronic pain condition that affects the trigeminal or
5th cranial nerve, one of the most widely distributed nerves in the head. TN is a form of neuropathic pain (pain
associated with nerve injury or nerve lesion.) The intensity of pain can be physically and mentally
incapacitating. It has been described as among the most painful conditions known to humankind. TN
symptoms begin appearing more frequently over the age of 50, although there have been cases with
patients being as young as three years of age. The incidence of new cases is approximately 12 per
100,000 people per year; the disorder is more common in women than in men.Trigeminal neuralgia was first
described by physician John Fothergill and treated surgically by John Murray Carnochan, both of
whom were graduates of the University of Edinburgh Medical School.
The trigeminal nerve is a paired cranial nerve that has three major branches: the ophthalmic
nerve (V1), the maxillary nerve (V2), and the mandibular nerve (V3). One, two, or all three branches of
the nerve may be affected. 10–12% of cases occur on both sides of the face. Trigeminal neuralgia
most commonly involves the middle branch (the maxillary nerve or V2) and lower branch (mandibular
nerve or V3) of the trigeminal nerve,[6] but the pain may be felt in the ear, eye, lips, nose, scalp,
forehead, cheeks, teeth, or jaw and side of the face.
TN is not easily controlled but can be managed with a variety of treatment options.TN is typified by
attacks that stop for a period of time and then return, but the condition can be progressive. The attacks often
worsen over time, with fewer and shorter pain-free periods before they recur. Eventually, the pain-free intervals
disappear and medication to control the pain becomes less effective. The disorder is not fatal, but can be
debilitating. Due to the intensity of the pain, some individuals may avoid daily activities or social contacts
because they fear an impending attack. TN is a progressive disorder that often becomes resistant to
medication over time, individuals often seek surgical treatment
