By definition, all limb girdle muscular dystrophies (LGMD) cause progressive proximal weakness, [3] meaning weakness of the muscles on or close to the torso that worsens over time. Explicitly, LGMD preferentially affects muscles of the hip girdle, thigh, shoulder girdle, and/or upper arm. [8] [6] The muscle weakness is generally symmetric. [11]
Disease progresses slowly, and lifespan is shortened. Congenital muscular dystrophy includes several disorders with a range of symptoms. Muscle degeneration may be mild or severe. Problems may be restricted to skeletal muscle, or muscle degeneration may be paired with effects on the brain and other organ systems. [14]
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 ...
muscle disease, nerve disease Pseudohypertrophy , or false enlargement, is an increase in the size of an organ due to infiltration of a tissue not normally found in that organ. [ 1 ] It is commonly applied to enlargement of a muscle due to infiltration of fat or connective tissue, [ 2 ] famously in Duchenne muscular dystrophy .
Duchenne muscular dystrophy is a rare progressive disease which eventually affects all voluntary muscles and involves the heart and breathing muscles in later stages. Life expectancy is estimated to be around 25–26, [ 18 ] [ 58 ] but this varies.
In medicine, myopathy is a disease of the muscle [1] in which the muscle fibers do not function properly. Myopathy means muscle disease (Greek : myo- muscle + patheia -pathy : suffering). This meaning implies that the primary defect is within the muscle, as opposed to the nerves ("neuropathies" or "neurogenic" disorders) or elsewhere (e.g., the ...
Bethlem myopathy is a slowly progressive muscle disease characterized predominantly by contractures, rigidity of the spine, skin abnormalities and proximal muscle weakness. [ 5 ] [ 11 ] Symptoms may present as early as infancy, with typical contractures and hyperlaxity of joints; however, in some patients, symptoms may go unnoticed until ...
[23] [24] It is also a comorbidity of late-onset Pompe disease (Glycogen storage disease type II). [25] [26] As both hyper- and hypothyroidism disrupts muscle glycogen metabolism, it is important to keep in mind differential diagnoses and their comorbidities when trying to determine whether signs and symptoms are either primary or secondary ...
