Trigeminal Neuralgia Causes

Do you feel pain when you speak, eat, drink or shave? Probably you have a disorder in your fifth cranial verve, or also known as trigeminal nerve. This kind of disorder is one of facial pain syndromes and well recognized in the medical world as trigeminal neuralgia.

Trigeminal Neuralgia (TN) is characterized by sudden attacks and electric-shock like of facial pain. The pain from TN might last within seconds to several minutes.

The facial pain area depends on the affected branch(es) of your trigeminal nerve. At most of times, TN affects only one side of the face, but at some cases, TN patients experience facial pain on both sides at different times.

The pain is triggered spontaneously by sensory stimulation of the face, such as eating, drinking, talking, or touching the face.

Causes
There are several possible Trigeminal Neuralgia (TN) causes, but mostly happen when blood vessels compress the trigeminal nerve as it enters the brain stem. This accident mediates pain and sensation between the face and brain.

Nevertheless, further analysis about the cause of TN is necessary. Usually it combines reviews of the history of symptoms, neurological examination and a combination of medical examination. At the moment, there are no particular clinical tests to evidently diagnose cases of TN.

The summaries of known causes of TN are as follows:

  • Compression of a blood vessel on the root of the trigeminal nerve.
  • Tumour pressure on the trigeminal nerve
  • Pressure damage on the trigeminal nerve which is caused by surgical or dental procedure, infections, or injury to the face.
  • Demyelination of the nerve. At rare cases, TN destroys the sheaths that protect the nerve fibers (myelin sheats)
  • Genetically inherited (possibility in rare cases)
  • Unknown cause
