A neuromuscular disease is any disease affecting the peripheral nervous system (PNS),[a] neuromuscular junctions , or skeletal muscles , all of which are components of the motor unit .[4] muscle atrophy and weakness. Issues with sensation can also occur.
Neuromuscular diseases can be acquired or genetic . Mutations of more than 650 genes have shown to be causes of neuromuscular diseases.[5] [6] [7] degeneration , autoimmunity , toxins , medications , malnutrition , metabolic derangements , hormone imbalances , infection , nerve compression/entrapment , comprised blood supply , and trauma .[8]
Signs and symptoms [ edit ]
Symptoms of neuromuscular disease may include numbness , paresthesia , muscle atrophy , a pseudoathletic appearance , exercise intolerance , myalgia (muscle pain), fasciculations (muscle twitches), myotonia (delayed muscle relaxation), hypotonia (lack of resistance to passive movement), fixed muscle weakness (a static symptom ), or premature muscle fatigue (a dynamic symptom ).[2] [9] [10] [11]
Neuromuscular disease can be caused by autoimmune disorders,[1] [2] Ehlers–Danlos syndrome ,[12] heavy metal poisoning .[3] myelin , is seen in certain deficiency diseases, such as the failure of the body's system for absorbing vitamin B-12 .[3]
Diseases of the motor end plate include myasthenia gravis , a form of muscle weakness due to antibodies against acetylcholine receptor,[13] [14] Lambert–Eaton myasthenic syndrome (LEMS).[15] Tetanus and botulism are bacterial infections in which bacterial toxins cause increased or decreased muscle tone, respectively.[16] Muscular dystrophies , including Duchenne's and Becker's , are a large group of diseases, many of them hereditary or resulting from genetic mutations , where the muscle integrity is disrupted, they lead to progressive loss of strength and decreased life span.[17]
Further causes of neuromuscular diseases are:
Polymyositis
Inflammatory muscle disorders
Tumors
Diagnosis [ edit ]
Nerve conduction velocity (study)
Diagnostic procedures that may reveal muscular disorders include direct clinical observations. 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] electromyography [24] nerve conduction studies .[25] Genetic testing is an important part of diagnosing inherited neuromuscular conditions.[23]
Prognosis [ edit ]
Prognosis and management vary by disease.[citation needed
