The disease is characterized by slowly progressive weakness and wasting of both proximal muscles (located on or close to the torso) and distal muscles (close to hands or feet), most apparent in the finger flexors and knee extensors. [3] IBM is often confused with an entirely different class of diseases, called hereditary inclusion body ...
Disuse is a common cause of muscle atrophy and can be local (due to injury or casting) or general (bed-rest). The rate of muscle atrophy from disuse (10–42 days) is approximately 0.5–0.6% of total muscle mass per day although there is considerable variation between people. [ 5 ]
In 1850, François-Amilcar Aran was the first to describe a disorder he named "progressive muscular atrophy", a form of ALS in which only the lower motor neurons are affected. [126] In 1869, the connection between the symptoms and the underlying neurological problems were first described by Jean-Martin Charcot , who initially introduced the ...
The importance of correctly recognizing progressive muscular atrophy as opposed to ALS is important for several reasons. The prognosis is a little better. A recent study found the 5-year survival rate in PMA to be 33% (vs 20% in ALS) and the 10-year survival rate to be 12% (vs 6% in ALS). [1]
Polymyalgia rheumatica (or "muscle rheumatism") is an inflammatory condition that mainly occurs in the elderly; it is associated with giant-cell arteritis (It often responds to prednisolone). [18] Polymyositis is an autoimmune condition in which the muscle is affected. [19] Rhabdomyolysis is the breakdown of muscular tissue due to any cause ...
Chronic inflammatory demyelinating polyneuropathy (CIDP) is an acquired autoimmune disease of the peripheral nervous system characterized by progressive weakness and impaired sensory function in the legs and arms. [1]

Sarcopenia (ICD-10-CM code M62.84 [1]) is a type of muscle loss that occurs with aging and/or immobility. It is characterized by the degenerative loss of skeletal muscle mass, quality, and strength. The rate of muscle loss is dependent on exercise level, co-morbidities, nutrition and other factors.
