: Identifying specific autoantibodies is crucial for confirming autoimmune NMDs like Myasthenia Gravis.
: Disorders like Polymyositis involve direct inflammatory infiltration of muscle tissue, leading to fiber degeneration.
: The immune system mistakenly targets structural proteins. For instance, in Myasthenia Gravis , autoantibodies (such as AChR or MuSK) damage acetylcholine receptors, blocking the signals between nerves and muscles.
: Certain drugs, such as statins or cancer treatments, can induce Statin Myopathies or toxic neuropathies by interfering with cellular metabolism or inducing oxidative stress.
Acquired neuromuscular disorders (NMDs) encompass a broad spectrum of conditions affecting the peripheral nerves, muscles, and neuromuscular junctions that are not inherited genetically but rather developed through life . These disorders often stem from inflammatory, autoimmune, or toxic triggers, becoming increasingly prevalent in aging populations due to factors like medication side effects (e.g., statins) or paraneoplastic syndromes. Pathogenesis of Acquired NMDs
: Patients with severe muscle weakness, particularly in the chest or diaphragm, are at higher risk for respiratory complications and require monitoring during infections. Acquired Neuromuscular Disorders - Springer Nature
