Trigeminal neuralgia and multiple sclerosis: A Look at Their Association
In the world of neurological disorders, Trigeminal Neuralgia (TN) and Multiple Sclerosis (MS) are two conditions that often intertwine. For individuals with MS, TN can be a potential complication, and understanding its causes, symptoms, and treatment options is crucial.
Trigeminal Neuralgia in MS is primarily caused by the formation of demyelinating lesions, or plaques, at the root entry zone of the trigeminal nerve in the brainstem. These plaques disrupt normal nerve conduction, leading to pain. This mechanism differs from classical TN, which is mainly caused by compression of the trigeminal nerve root by aberrant blood vessels.
This form of TN in MS patients is classified as secondary TN due to an identifiable underlying neurological disease (MS). The MS-related plaques cause damage leading to ectopic impulse generation and possibly loss of inhibitory control in pain pathways. TN is more common in people with MS compared to the general population and often occurs in younger patients with MS, contrasting with classical TN, which generally affects older adults.
Other less common causes of TN include compressive lesions such as tumors or vascular abnormalities. However, in people with MS, the hallmark cause is the demyelinating plaque affecting the trigeminal nerve root.
Symptoms of TN include sudden, brief, stabbing, or electrical shock sensations that usually affect one side of the face. Anyone who feels an unusual, sharp pain around their eyes, lips, nose, jaw, forehead, or scalp and who has not recently had dental or facial surgery should talk with a doctor.
Doctors have not yet found a cure for TN, but a range of treatments may help relieve the symptoms. Depending on a person's symptoms and the severity of their condition, doctors may recommend one of three types of surgery for TN: Microvascular decompression, where a person undergoes a general anesthetic to open up the skull and move a blood vessel away from the nerve; Stereotactic radiosurgery, which uses a concentrated radiation beam to injure the trigeminal nerve and block the pain signals; and Percutaneous procedures, which involve making small incisions to reach the nerve and perform various treatments.
In addition to surgery, other therapies a person can try to reduce the effects of TN include Botox injections, Acupuncture, dietary changes, reflexology, and hyperbaric or high dose oxygen therapy.
For those with MS, managing TN is part of a broader approach to managing the disease. A person's MS treatment may include treatment for relapses of MS symptoms using steroids, treatment for specific MS symptoms such as TN, and lowering the number of relapses with disease-modifying therapy.
While TN is not life-threatening, it can cause lifelong pain and disablement. Complications of TN can include depression, facial twitches, permanent numbness, corneal anesthesia, jaw weakness, anesthesia dolorosa, and long-term anticonvulsant use causing adverse effects.
With a correct diagnosis and appropriate management, a person can expect a positive outlook. If you or someone you know is experiencing symptoms of TN, it's essential to seek medical advice promptly.
