Definition Return to top
Sensorimotor polyneuropathy is a decrease in movement or ability to feel (sensation).
Causes Return to top
Polyneuropathy means disease of nerves. Sensorimotor polyneuropathy is damage to nerves other than the brain or spinal cord. Such nerve damage is called peripheral neuropathy.
Sensorimotor polyneuropathy is a body-wide (systemic) process that damages nerve cells, nerve fibers (axons), and nerve coverings (myelin sheath). Damage to the covering of the nerve cell causes nerve signals to slow down. Damage to the nerve fiber or entire nerve cell can make the nerve stop working.
Nerve damage can be caused by:

Medications used to treat this condition:
Avoid pain medication whenever possible, or use it only when necessary. Keeping your body in the proper position or keeping bed linens off a tender body part may help control pain.
Outlook (Prognosis) Return to top
You can fully recover from peripheral neuropathy if your health care provider can find the cause and successfully treat it, and if the damage does not affect the entire nerve cell.
The amount of disability varies. Some people have no disability, while others have a partial or complete loss of movement, function, or feeling. Nerve pain may be uncomfortable and may last for a long time.
Occasionally sensorimotor polyneuropathy causes severe, life-threatening symptoms.
