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 ...
Eventually, rigidified muscles reduce the affected person's range of motion, slow their voluntary movements, and may cause them to have abnormal posture, particularly lumbar hyperlordosis (a distinctive curve in the lower back). [6] Rigid trunk muscles can also prevent the chest and abdomen from expanding, causing shortness of breath and early ...
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 ...
Knowing the cause of your back pain is an important first step. While there are many obvious reasons for back pain, there are some that may surprise you. To learn more about causes and treatment ...
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
Weakness of the muscles that move the jaw (muscles of mastication) may cause difficulty chewing. In individuals with MG, chewing tends to become more tiring when chewing tough, fibrous foods. [ 16 ] Difficulty in swallowing, chewing, and speaking is the first symptom in about one-sixth of individuals.
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.
Muscle atrophy is the loss of skeletal muscle mass. It can be caused by immobility, aging, malnutrition, medications, or a wide range of injuries or diseases that impact the musculoskeletal or nervous system. Muscle atrophy leads to muscle weakness and causes disability.
