Sensorimotor polyneuropathy causes a decreased ability to move or feel (sensation) due to nerve damage.
Polyneuropathy - sensorimotor
Causes, incidence, and risk factors
Neuropathy means a disease of, or damage to nerves. When it occurs outside of the brain or spinal cord, it is called a peripheral neuropathy. Mononeuropathy means one nerve is involved. Polyneuropathy means that many nerves in different parts of the body are involved.
Neuropathy can affect nerves that provide feeling (sensory neuropathy) or cause movement (motor neuropathy). It can also affect both, in which case it is called a sensorimotor 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:
Autoimmune (body-wide) disorders
Conditions that put pressure on nerves
Decreased blood flow to the nerve
Diseases that destroy the glue (connective tissue) that holds cells and tissues together
Swelling (inflammation) of the nerves
Some diseases lead to polyneuropathy that is mainly sensory or mainly motor. Possible causes of sensorimotor polyneuropathy include:
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.
