: 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.
The underlying mechanisms of acquired neuromuscular disorders typically involve an immune-mediated or metabolic disruption of the motor system: Acquired Neuromuscular Disorders: Pathogenesis,...
: Use of steroids, immunosuppressants, or advanced biologics to halt autoimmune destruction. : The immune system mistakenly targets structural proteins
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 leading to fiber degeneration.
Treatment for acquired NMDs is largely clinically oriented and tailored to the specific etiology:
: Electromyography (EMG) and nerve conduction studies are used to distinguish between primary muscle issues (myopathies) and nerve issues (neuropathies).
: Disorders like Polymyositis involve direct inflammatory infiltration of muscle tissue, leading to fiber degeneration.
