Nerve conduction studies are beneficial to diagnose certain diseases of the nerves of the body. The test is not invasive, but can be painful due to the electrical shocks administered during the test. The shocks are associated with a low amount of electric current, so they pose minimal risk to the patients.
Patients with hereditary motor and sensory neuropathies are diagnosed through a physical evaluation that looks for muscle atrophy, weakness, and sensory responses. [3] In addition to this, electromyography and motor nerve conduction tests can help clinicians decide what type of motor and sensory neuropathy it is and how severe the disease is.
Hereditary neuropathy with liability to pressure palsy (HNPP) is a peripheral neuropathy, a condition that affects the nerves. [4] Pressure on the nerves can cause tingling sensations, numbness , pain, weakness, muscle atrophy and even paralysis of the affected area.
Motor nerve action potentials and conduction are usually unaffected, but in a subset of cases may have limited dysfunction. [2] Analysis of the cerebrospinal fluid may show increased protein, pleocytosis and oligoclonal bands but this is non-specific. [2] [1] Biopsy of the dorsal nerve root ganglions show a characteristic CD8+ T-cell ...
Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve , though this may also refer to nerve root compression (by a herniated disc , for example).
Micrograph showing peripheral neuropathy . Polyneuropathy is peripheral neuropathy occurring in the same areas on both sides of the body. Specialty: Neurology Symptoms: Ataxia [1] Causes: Hereditary (Charcot–Marie–Tooth disease), and acquired (alcohol use disorder) [2] Diagnostic method: Nerve conduction study, urinalysis [3] [1] Treatment
