How does Sjögren's Disease impact the peripheral nervous system?

Sjögren's Disease can significantly impact the peripheral nervous system. More than half of patients with Sjögren's Disease who experience neurological symptoms may not have the autoantibodies typically linked to the disease. This condition can cause peripheral neuropathy, affecting patients' daily life by damaging peripheral nerves, such as those in the arms and legs. This damage may lead to various symptoms, including numbness, abnormal sensitivity to temperature, and weakness.

Diagnosis of peripheral neuropathy starts with an in-depth review of the patient's medical history and a comprehensive neurological examination to detect any signs of peripheral nerve damage. If the examination indicates peripheral neuropathy, a nerve conduction test may be conducted to evaluate the health of the nerves and muscles.

It's essential to note that traditional nerve-conduction tests primarily identify damage in large-fiber nerves, potentially missing small-fiber neuropathy. If small-fiber neuropathy is suspected, a skin biopsy may be carried out to examine any damage to the smaller nerves.

Furthermore, Sjögren’s Disease may result in various other types of neuropathies. This includes autonomic neuropathy, which affects essential body functions such as heartbeat, respiration, and gastric motility. Glossopharyngeal neuralgia and trigeminal neuralgia are also possible, causing pain, numbness, or burning sensations in the face and throat. There's also a rare, but severe, form of neuropathy called mononeuritis multiplex, causing weakness or even paralysis in different muscles due to inflammation of small blood vessels surrounding the nerves.

In conclusion, these neurological manifestations of Sjögren’s Disease require an all-inclusive diagnostic evaluation and careful management. Treatment plans may include the use of immunosuppressant medications.
