Definition


Polyneuropathy is a neurological disorder localized in the peripheral nervous system, outside of the brain and spinal cord. It is usually the ends of the nerve fibers of the longest nerves that are affected, hence why the condition frequently affects the feet and lower limbs. The attack is often symmetrical, manifesting on both sides of the body equally. Chronic alcoholism leads to alcoholic polyneuropathy, diabetes to diabetic neuropathy, medication, especially during chemotherapy is also a cause, and even kidney failure can be responsible. Loss of feeling, sensory problems such as pins and needles, pricking sensations, and, more rarely, motor impairment in the lower limbs, are all symptoms. There is no specific treatment for this condition except those adapted to the underlying cause.
