"Peripheral neuropathy results from damage to the nerves outside the brain and spinal cord. This medical condition refers to the various situations that involve damage to the peripheral nervous system, as well as peripheral nerves. The peripheral nervous system is a vast communication network that sends signals between the central nervous system (the brain and spinal cord) and the other parts of the body. Peripheral neuropathy can cause weakness, numbness, and pain, usually in the feet and hands. But it can also affect other bodily functions, including digestion, urination, and circulation.Most instances of neuropathy are either acquired meaning the inevitability of getting it isn"t present from the beginning of life or genetic. Acquired neuropathies are either symptomatic, which means they result from another disorder or condition, or idiopathic (meaning it has no known cause). The symptoms of peripheral neuropathy depend on the affected type of nerve. Each nerve has a specific function. There are sensory nerves, motor nerves, and autonomic nerves.The small-fiber neuropathies that present with pain, itch, and autonomic symptoms also can be genetic. As our understanding of genetic disorders increases, many new genes are being associated."
