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.
The nerve conduction study is often combined with needle electromyography. The Department of Health and Human Services Inspector General recently identified the use of NCSs without a needle electromyography at the same time a sign of questionable billing. [9] The nerve conduction study consists of the following components:
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).
Although diseases often are suggested by the physical examination and history alone, tests that may be employed include electrodiagnostic testing, serum protein electrophoresis, nerve conduction studies, urinalysis, serum creatine kinase (CK) and antibody testing; nerve biopsy is done sometimes.

Sensory neuronopathy is diagnosed clinically, based on signs and symptoms, along with nerve conduction studies. [1] Ataxia in the upper and lower extremities at onset or at full development, asymmetric distribution of sensory loss, sensory loss not being restricted to the lower limbs (as in length dependent axonal polyneuropathy) are specific ...
Electrodiagnostics – electromyography (EMG) and nerve conduction study (NCS). In usual CIDP, the nerve conduction studies show demyelination. These findings include: [citation needed] a reduction in nerve conduction velocities; the presence of conduction block or abnormal temporal dispersion in at least one motor nerve;
This usually starts with the observation of bulk, possible atrophy or loss of muscle tone. Neuromuscular disease can also be diagnosed by various blood tests and using electrodiagnostic medicine tests [23] including electromyography [24] (measuring electrical activity in muscles) and nerve conduction studies. [25]
Diagnosis typically involves serum tests to measure elevated levels of vitamin B 6, along with nerve conduction studies and other neurodiagnostic evaluations. [ 4 ] [ 14 ] [ 15 ] [ 16 ] This condition underscores the importance of moderation in the use of dietary supplements, highlighting that even substances generally safe at recommended ...
