A neuromuscular disease is any disease affecting the peripheral nervous system (PNS), [a] the neuromuscular junctions, or skeletal muscles, all of which are components of the motor unit. [4] Damage to any of these structures can cause muscle atrophy and weakness. Issues with sensation can also occur. Neuromuscular diseases can be acquired or ...
This article provides a list of autoimmune diseases. These conditions, where the body's immune system mistakenly attacks its own cells, affect a range of organs and systems within the body. Each disorder is listed with the primary organ or body part that it affects and the associated autoantibodies that are typically found in people diagnosed ...
Autoantibodies to components of the Ranvier nodes, specially autoantibodies the Contactin-associated protein 1 , cause a form of CIDP with an acute "Guillain-Barre-like" phase, followed by a chronic phase with progressive symptoms. Different IgG subclasses are associated with the different phases of the disease.
Neuromuscular junction diseases can also be referred to as end plate diseases or disorders. [citation needed] Among neuromuscular diseases some can be autoimmune disease, or hereditary disorders. They can affect either presynaptic mechanisms or postsynaptic mechanisms, preventing the junction from functioning normally.
Distal muscular dystrophy, also called distal myopathy, is essentially any muscle disease that preferentially affects the hands and/or feet, a much less common pattern than proximal muscle weakness. Late adult-onset type 1; Late adult-onset type 2a; Late adult-onset type 2b; Early adult-onset type 1; Early adult-onset type 2; Early adult-onset ...
MG is an autoimmune disease in which individuals form antibodies that circulate in their blood, enter tissues, bind to certain proteins in the neuromuscular junctions of skeletal muscles, and thereby reduce the number or ability of these skeletal muscles to contract when appropriately stimulated by acetylcholine. The affected skeletal muscles ...
Chronic and progressive onset of autonomic symptoms may indicate diabetes, amyloidosis, or Sjogren's syndrome. AAG can be difficult to distinguish from degenerative autonomic disorders such as pure autonomic failure or multiple system atrophy when autonomic symptoms appear gradually. When the time course is unknown, the presence of prominent ...
The diagnosis is usually confirmed with electromyography and blood tests; these also distinguish it from myasthenia gravis, a related autoimmune neuromuscular disease. [4] If the disease is associated with cancer, direct treatment of the cancer often relieves the symptoms of LEMS.
