What is trigeminal neuralgia, and how is it treated?
Trigeminal neuralgia is a condition that causes episodes of stinging or shock-like pain in the face. It is caused by damage or pressure on the trigeminal nerve, which provides feeling to the face. Certain medications and surgical procedures can help to improve the pain of trigeminal neuralgia. PeopleImages/E+ via Getty Images.
Can people with trigeminal neuralgia drink coffee?
Trigeminal neuralgia is more common among women than men, and it is more likely to occur in people over 50. People with trigeminal neuralgia should avoid drinking coffee because coffee contains a lot of caffeine which will stimulate nerves and trigger arteriolar spasm, causing the deterioration of the disease. Besides, people with trigeminal neuralgia should avoid greasy or spicy foods, limit alcohol drinking and smoking.
What is the main cause of trigeminal neuralgia?
What causes trigeminal neuralgia? TN is associated with a variety of conditions. TN can be caused by a blood vessel pressing on the trigeminal nerve as it exits the brain stem. This compression causes the wearing away or damage to the protective coating around the nerve (the myelin sheath).

Pain in the head and neck is mediated by sensory (afferent) nerve fibers in the trigeminal nerve, glossopharyngeal and vagus nerves, and the upper cervical roots via the occipital nerves.
What does the trigeminal nerve detect?
In neuroanatomy, the trigeminal nerve (lit. triplet nerve), also known as the fifth cranial nerve, cranial nerve V, or simply CN V, is a cranial nerve responsible for sensation in the face and motor functions such as biting and chewing; it is the most complex of the cranial nerves.

Disruptions of the trigeminal nerve caused by neuralgia may also induce or contribute to tinnitus by affecting the vasculature of the inner ear. The trigeminal nerve is the source of innervation for blood vessels around the spiral modiolus and the stria vascularis of inner ear [31, 38].
What is the trigeminal nerve?
As the name suggests, the trigeminal nerve is a tripartite entity made up of distinct terminal divisions. Each component of the nerve is responsible for a specific region of the face, and transmits specific impulses. The three divisions of the trigeminal nerve are:
How do axons form the mesencephalic tract?
As the myelinated axons leave the mesencephalic nucleus, they coalesce to form the mesencephalic tract. The individual axon s then split into central and peripheral branches. The central branches convey impulses from the neuromuscular spindles within the muscles of mastication, and from the bite force reflex arcs, to the motor neuron of the trigeminal nerve. Other central fibers also integrate with the reticular formation and the sensory trigeminal nerve. Others also gain access to the cerebellum by way of the superior cerebellar peduncle. This interplay between the proprioceptive and motor divisions of the trigeminal nerve helps to regulate the activity of the stretch muscles; and by extension, the process of mastication.

How does a rhizotomy for trigeminal neuralgia work?
The surgeon inserts a long needle through the cheek on the affected side of the face and uses an electrical current (heat) or a chemical (glycerin or glycerol) to deaden the pain fibers of the trigeminal nerve. For those undergoing trigeminal neuralgia rhizotomy for the first time, the chemical approach is typically recommended.

Does TMJ Trigger All Migraines?
Based on how unevenly people respond to migraine treatments, it seems likely that there are many different causes of migraines. For many people, TMJ treatment works great, and it involves no drugs and has few side effects. It’s a great treatment option, and people who haven’t tried it should consider it, especially if they have other symptoms associated with TMJ like tinnitus, neck pain, and damage or excessive wear on teeth.
