How do you get neuromuscular disease?
Neuromuscular disorders can be inherited or caused by a spontaneous gene mutation; some also may be caused by immune system disorders.
What is considered a neuromuscular disease?
Neuromuscular disorders include a wide-range of diseases affecting the peripheral nervous system, which consists of all the motor and sensory nerves that connect the brain and spinal cord to the rest of the body. Progressive muscle weakness is the predominant condition of these disorders.

What does neuromuscular pain feel like?
Nerve pain often feels like a shooting, stabbing or burning sensation. Sometimes it can be as sharp and sudden as an electric shock. People with neuropathic pain are often very sensitive to touch or cold and can experience pain as a result of stimuli that would not normally be painful, such as brushing the skin.
Can neuromuscular disorders be cured?
There is currently no treatment that can cure neuromuscular disorders. Treating symptoms, delaying disease progression, and enhancing the quality of life for patients are achieved with medications, physical therapy, occupational therapy, and, when necessary, surgery.

What is neuromuscular disorder?
Neuromuscular disorders are conditions that affect the nerves that send electrical signals to muscles to control movement. When the nerves are damaged, communication between the nerves and muscles becomes disrupted. This results in significant muscle weakness, wasting, and loss of function.

Overview
A neuromuscular disease is any disease affecting the peripheral nervous system (PNS), the neuromuscular junction, or skeletal muscle, all of which are components of the motor unit. Damage to any of these structures can cause muscle atrophy and weakness. Issues with sensation can also occur.
Neuromuscular diseases can be acquired or genetic. Mutations of more than 500 genes have sh…
Signs and symptoms
Symptoms of neuromuscular disease may include numbness, paresthesia, muscle weakness, muscle atrophy, myalgia (muscle pain), and fasciculations (muscle twitches).
Causes
Neuromuscular disease can be caused by autoimmune disorders, genetic/hereditary disorders and some forms of the collagen disorder Ehlers–Danlos syndrome, exposure to environmental chemicals and poisoning which includes heavy metal poisoning. The failure of the electrical insulation surrounding nerves, the myelin, is seen in certain deficiency diseases, such as the failure of the body's system for absorbing vitamin B-12.
Diagnosis
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 including electromyography (measuring electrical activity in muscles) and nerve conduction studies. Genetic testing is an important part of diagnosing inherited neuromuscular c…
Prognosis
Prognosis and management vary by disease.
