Peripheral neuropathy may be classified according to the number and distribution of nerves affected (mononeuropathy, mononeuritis multiplex, or polyneuropathy), the type of nerve fiber predominantly affected (motor, sensory, autonomic), or the process affecting the nerves; e.g., inflammation (), compression (compression neuropathy), chemotherapy (chemotherapy-induced peripheral neuropathy).
Small fiber peripheral neuropathy is a type of peripheral neuropathy that occurs from damage to the small unmyelinated and myelinated peripheral nerve fibers. These fibers, categorized as C fibers and small Aδ fibers , are present in skin , peripheral nerves , and organs. [ 1 ]
Chronic inflammatory demyelinating polyneuropathy (CIDP) is an acquired autoimmune disease of the peripheral nervous system characterized by progressive weakness and impaired sensory function in the legs and arms. [1]
Proximal diabetic neuropathy, also known as diabetic amyotrophy, is a complication of diabetes mellitus that affects the nerves that supply the thighs, hips, buttocks and/or lower legs. Proximal diabetic neuropathy is a type of diabetic neuropathy characterized by muscle wasting, weakness, pain, or changes in sensation/numbness of the leg.
The diagnosis of polyneuropathy begins with a history (anamnesis) and physical examination to ascertain the pattern of the disease process (such as arms, legs, distal, proximal), if they fluctuate, and what deficits and pain are involved.

In 2020 the NIH quoted an estimate that in the United States 25% to 66% of chronic alcohol users experience some form of neuropathy. [7] The rate of incidence of alcoholic polyneuropathy involving sensory and motor polyneuropathy has been stated as from 10% to 50% of alcoholics depending on the subject selection and diagnostic criteria.
Globally diabetic neuropathy affects approximately 132 million people as of 2010 (1.9% of the population). [41] Diabetes is the leading known cause of neuropathy in developed countries, and neuropathy is the most common complication and greatest source of morbidity and mortality in diabetes.
Symptoms of sensory neuropathy may sometimes precede the cancer diagnosis by several months. Immune mediated sensory neuronopathy is commonly associated with Sjogrens syndrome. [5] Sjogren's is most commonly affected by a length dependent axonal sensorimotor neuropathy characterized by symptoms in the extremities.
