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).
Autoimmune variants peripheral neuropathies or progressive inflammatory neuropathy could be in the list assuming the autoimmune model for MS, together with a rare demyelinating lesional variant of trigeminal neuralgia [104] [failed verification] and some NMDAR Anti-NMDA receptor encephalitis. [54]
Sural nerve biopsy; biopsy is considered for those patients in whom the diagnosis is not completely clear, when other causes of neuropathy (e.g., hereditary, vasculitic) cannot be excluded, or when profound axonal involvement is observed on EMG. Ultrasound of the peripheral nerves may show swelling of the affected nerves. [32] [33] [34]
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. If pain is a factor, determining where and how long it has been present is important; one also needs to ...
Progressive inflammatory neuropathy is a autoimmune disease that was identified in a report, released on January 31, 2008, by the Centers for Disease Control and Prevention. [1] The first known outbreak of this neuropathy occurred in southeastern Minnesota in the United States .
The causes of nerve damage are grouped into categories including those due to paraneoplastic causes (neuropathy secondary to cancer), immune mediated, infectious, inherited or degenerative causes and those due to toxin exposure. In idiopathic sensory neuronopathy no cause is identified. Idiopathic causes account for about 50% of cases. [2]
Peripheral artery disease most commonly affects the legs, but other arteries may also be involved, such as those of the arms, neck, or kidneys. [4] [17] Peripheral artery disease (PAD) is a form of peripheral vascular disease. Vascular refers to both the arteries and veins within the body. PAD differs from peripheral veinous disease. PAD means ...
A skin biopsy for the measurement of epidermal nerve fiber density is an increasingly common technique for the diagnosis of small fiber peripheral neuropathy. [13] Physicians can biopsy the skin with a 3-mm circular punch tool and immediately fix the specimen in 2% paraformaldehyde lysine-periodate or Zamboni's fixative. [20]
