A problem within the peripheral nervous system is indicated by neuropathy, also called peripheral neuropathy. The network of nerves outside of your brain and spinal cord is your peripheral nervous system. Your central nervous system is made up of the brain and the spinal cord.
Neuropathy occurs when there is disruption or loss of nerve cells, called neurons. This disrupts the manner in which the neurons connect with each other and the brain. Neuropathy can affect one nerve (mononeuropathy) or type of nerve, a limited-area nerve combination (multifocal neuropathy), or multiple peripheral nerves throughout the body (polyneuropathy).
