Peripheral neuropathy

Peripheral neuritis; Neuropathy - peripheral; Neuritis - peripheral; Nerve disease; Polyneuropathy; Chronic pain - peripheral neuropathy

Peripheral nerves carry information to and from the brain. They also carry signals to and from the spinal cord to the rest of the body.

Peripheral neuropathy means these nerves don't work properly. Peripheral neuropathy may occur because of damage to a single nerve or a group of nerves. It may also affect nerves in the whole body.

Nervous system

Peripheral Neuropathy is not a distinct disease, but the manifestation of many conditions that damage the peripheral nerves (nervous tissue other than the brain and spinal cord). Symptoms depend on whether sensory nerves (the nerves that transmit sensory information from the body to the brain and spinal cord) or motor nerves (the nerves that transmit impulses from the brain and spinal cord to the body) are affected. If the sensory nerves are damaged, sensation may be diminished, lacking or abnormal. Damaged motor nerves impair movement or function. Peripheral neuropathy may be caused by direct or indirect injury, or by a systemic cause such as a metabolic disorder.

Central nervous system

The central nervous system is comprised of the brain and spinal cord. The peripheral nervous system includes all peripheral nerves.
