General

Neuropathy is a general term for diseases of the peripheral nervous system. The peripheral nerves include all the nerves outside the brain or spinal cord. The peripheral nervous system has many functions, including movement, sensing, and control of internal organs. Neuropathy can affect one nerve (called mono-neuropathy), two or more nerves (called multiplex neuropathy), or as in most cases, a large number of nerves (called poly-neuropathy). There are many causes of neuropathy. The most common cause in the Western world is diabetes. Neuropathy may also develop as a complication of other diseases, such as kidney failure, liver failure, autoimmune diseases, and more. Neuropathy can be a side effect of medications. In some cases, the cause of the neuropathy remains unknown.
