Distal symmetric polyneuropathy (DSPN) is a type of peripheral neuropathy that affects the nerves in the extremities, particularly the feet and legs. It is one of the most common forms of neuropathy and is often associated with conditions such as diabetes. The term "distal symmetric" refers to the fact that the nerve damage tends to occur in a symmetrical pattern, affecting both sides of the body and typically starting in the furthest (distal) parts of the limbs.
