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 ...
Inflammatory myopathy, also known as idiopathic inflammatory myopathy (IIM), is disease featuring muscle weakness, inflammation of muscles , and in some types, muscle pain . The cause of much inflammatory myopathy is unknown ( idiopathic ), and such cases are classified according to their symptoms and signs , electromyography , MRI , and ...
Inclusion body myositis (IBM) (/ m aɪ oʊ ˈ s aɪ t ɪ s /) (sometimes called sporadic inclusion body myositis, sIBM) is the most common inflammatory muscle disease in older adults. [2]
Common types of myopathy due to statins include myalgia, myositis, and rhabdomyolysis. Statins induce myopathy by inhibiting protein synthesis within the muscle. [6] Statin therapy tends to not show any histopathological differences, and thus a biopsy does not reveal too much about the damage. Often, the damage is found within the mitochondria. [1]
Polymyositis and the associated inflammatory myopathies have an associated increased risk of cancer. [3] The features they found associated with an increased risk of cancer were older age, age greater than 45, male sex, difficulty swallowing, death of skin cells, cutaneous vasculitis, rapid onset of myositis (<4 weeks), elevated creatine kinase, higher erythrocyte sedimentation rate and higher ...
Distal myopathy is a group of rare genetic disorders that cause muscle damage and weakness, predominantly in the hands and/or feet. Mutation of many different genes can be causative. Mutation of many different genes can be causative.
Cardiomyopathy is a group of primary diseases of the heart muscle. [1] Early on there may be few or no symptoms. [1] As the disease worsens, shortness of breath, feeling tired, and swelling of the legs may occur, due to the onset of heart failure. [1]
Muscle weakness is a lack of muscle strength. Its causes are many and can be divided into conditions that have either true or perceived muscle weakness. True muscle weakness is a primary symptom of a variety of skeletal muscle diseases, including muscular dystrophy and inflammatory myopathy.
