Nerve involvement in Sjogren's Syndrome

Nerve Problems

People with Sjögren's syndrome can have nerve problems. When they do, the problem usually involves the peripheral nervous system (PNS), which contains the nerves that control sensation and movement. Involvement of the PNS is increasingly being recognized.


 Carpal tunnel syndrome, peripheral neuropathy, and cranial neuropathy are examples of peripheral nervous system disorders that occur in people with Sjögren's. 

In carpal tunnel syndrome, inflamed tissue in the forearm presses against the median nerve, causing pain, numbness, tingling, and sometimes muscle weakness in the thumb and index and middle fingers. 

In peripheral neuropathy, an immune attack damages nerves in the legs or arms, causing the same symptoms there. (Sometimes nerves are damaged because inflamed blood vessels cut off their blood supply.) 

In cranial neuropathy, nerve damage causes face pain; loss of feeling in the face, tongue, eyes, ears, or throat; and loss of taste and smell.

Nerve problems are treated with medicines to control pain and, if necessary, with steroids or other drugs to control inflammation.

 

Polyneuropathy is when multiple peripheral nerves become damaged, which is also called peripheral neuropathy.

Peripheral nerves are the nerves outside of the brain and spinal cord. They relay information between the central nervous system (brain and spinal cord) and other parts of the body. 

Polyneuropathy means several nerves in different parts of the body are affected at the same time. Polyneuropathy can affect the nerves responsible for feeling (sensory neuropathy), movement (motor neuropathy), or both which is called sensorimotor neuropathy. It may also affect the autonomic nerves which control functions such as digestion, the bladder, blood pressure, and heart rate.

Mononeuropathy means one nerve is affected.

Polyneuropathy is diagnosed with:

  • A doctor's evaluation of the symptoms

  • Electromyography and nerve conduction studies

  • Blood and urine tests to decide te cause
