Who Is At Risk For Trigeminal Neuralgia?

The precise lawsuit of trigeminal neuralgia ( TN ) is not have a go at it , it is believed that damage or pressure to the trigeminal mettle may be the cause of the disease . The “ ignition theory ” is the master hypothesis which states that TN is due to abnormalities in the afferent nerves of the trigeminal root or ganglion . Damage to the axone can make the nerve cell hyperexcitable and cause pain leading to painfulneuropathy .

The vascular densification is another theory . Peripheral and central mechanism can cause damage and air pressure and alter the trigeminal nerve microstructure however , there is no apparent disease seen in the trigeminal boldness . The scathe or air pressure can be from a blood vessel near the trigeminal nerve root near its entry to the pons which can iron out , legal injury or bother the nerve or it can be due to a hereditary disorder in the blood vessels . The vascular compression possibility can be supported by the surgical decompressing and MRI finding however , not all trigeminal neuralgia patients have apparent vascular compression .

Since the accurate cause is not known the peril factors are not know precisely but according to studies done on patient ’s diagnosed with trigeminal neuralgia , the following can be risk factors :

Age : trigeminal neuralgia is seen most of the time in people older than 50 years ( the range is between 37 - 67 years ) . It ’s rarified in masses less than 50 days unless they have another risk factor such as multiple induration or a tumor

Gender : charwoman are more prone to get trigeminal neuralgia than men , the ratio is about 3:1 .

Tumor In The Nervous System : tumour nigh to a root of the trigeminal nerve can press , irritate or damage the nerve giving rise to the trigeminal neuralgia symptoms .

Multiple Sclerosis : The relative risk of getting trigeminal neuralgia in patients with multiple induration is 20 % . hurt to the medulla sheath of the trigeminal nerve can cause induration in the brass leading to trigeminal neuralgy .

Hypertension : high blood pressure is a peril factor for adult female and men . The relative risk is about 2.1 % for women and 1.53 % for work force . Hypertension is considered a danger ingredient for fair sex more than men .

Charcot - Marie - Tooth Disease : It ’s an inherited motor and sensory neuropathy.(1 ) ( 2 ) ( 3 )

Is There A Blood Test For It?

diagnosing of trigeminal neuralgia is based on account and examination mainly , it ’s a clinical diagnosis . There are n’t any specific exam to support the diagnosing . There is n’t any ancestry exam to name trigeminal neuralgy . However , magnetic resonance mental imagery ( MRI ) can be done to identify secondary causes such as multiple induration or tumors that irritate the trigeminal spunk . Routine neuroimaging detects a movement in 15 % of the patients . MRI seldom find the precise movement of trigeminal neuralgia as vessel next to the nerve is difficult to see even in a in high spirits - result MRI but sometimes vascular contraction can be find by a high - resolution MRI . Investigations can be done to keep out other causes of facial pain . sensorial testing , evoked potentials , and electrophysiological studies can also serve discover TN but it ’s not recommended as routine tests for patient .

Conclusion

The exact cause of trigeminal neuralgy is not known , it can be due to abnormalities in the afferent nerves of trigeminal ascendant or ganglion or it can be due to vascular compressing from rip vessel . Therefore , the exact risk of infection divisor are not know but allot to written report done on affected role diagnosed with trigeminal neuralgia the followers can be risk factors : older years , female gender , tumour in the nervous system , multiple sclerosis , stroke , high blood pressure , and Charcot- Marie - Tooth disease . There are n’t any blood tests to confirm trigeminal neuralgia , it ’s principally a clinical diagnosis . Neuroimaging especially MRI may project vascular compression in some patients but in most cases , the MRI would be normal . Sensory examination , elicit potentials , neuroimaging , and electrophysiological studies can be done to shut other causal agent of facial pain.(4 ) ( 5 )
