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 ]
Alcoholic polyneuropathy is a neurological disorder in which peripheral nerves throughout the body malfunction simultaneously.It is defined by axonal degeneration in neurons of both the sensory and motor systems and initially occurs at the distal ends of the longest axons in the body.
Distal axonopathy, is the result of interrupted function of the peripheral nerves. [9] It is the most common response of neurons to metabolic or toxic disturbances, and may be caused by metabolic diseases such as diabetes , kidney failure , connective tissue disease , deficiency syndromes such as malnutrition and alcoholism , or the effects of ...
In 1982 Lewis et al. reported a group of patients with a chronic asymmetrical sensorimotor neuropathy mostly affecting the arms with multifocal involvement of peripheral nerves. [47] Also in 1982 Dyck et al reported a response to prednisolone to a condition they referred to as chronic inflammatory demyelinating polyradiculoneuropathy. [ 48 ]
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.
The Therapeutic Goods Administration requires a label warning about peripheral neuropathy if the daily dose is predicted to exceed 10 mg/day. [47] [48] U.S. Institute of Medicine - Food and Nutrition Board 100 mg/day The adult UL was set in 1998 and has not been updated as of 2024 [24]
Chemotherapy-induced peripheral neuropathy (CIPN) is a nerve-damaging side effect of antineoplastic agents in the common cancer treatment, chemotherapy. [1] CIPN afflicts between 30% and 40% of patients undergoing chemotherapy.
