Frailty is a common and clinically significant grouping of symptoms that occurs in aging and older adults. These symptoms can include decreased physical abilities such as walking, excessive fatigue, and weight and muscle loss leading to declined physical status.
There are many proposed causes of sarcopenia and it is likely the result of multiple interacting factors. Understanding of the causes of sarcopenia is incomplete, however changes in hormones, immobility, age-related muscle changes, nutrition and neurodegenerative changes have all been recognized as potential causative factors.
Idiopathic primary BSS is a late-onset myopathy with progressive muscular weakness that is detected on the spinal extensor muscles in elderly patients and is more predominant in females. [2] The pathogenesis of primary BSS is typically related to fibrosis and fatty infiltration of muscular tissues and to mitochondrial changes due to the aging ...
You could be one of millions of people with chronic fatigue syndrome appeared first on TheGrio. Chronic fatigue syndrome clearly “is not a rare illness,” said the CDC’s Dr. Elizabeth Unger ...
In people with sIBM, the muscle cells display "flags" telling the immune system that they are infected or damaged (the muscles ubiquitously express MHC class I antigens) and this immune process leads to the death of muscle cells. The chronic stimulation of these antigens also causes stress inside the muscle cell in the endoplasmic reticulum (ER ...
Sarcopenia describes the muscle loss that often occurs in older age. Individuals with higher levels of muscle loss are more at risk of adverse health outcomes, including falls and fractures.
The causes are many and can be divided into conditions that have 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. It occurs in neuromuscular junction disorders, such as myasthenia gravis. [citation needed]
Further causes of neuromuscular diseases are: Polymyositis. Inflammatory muscle disorders. 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 ...
