What is the main cause of muscle atrophy?

? Muscle atrophy is caused by the fact that muscle fibers of human body become smaller or disappear, which leads to muscle atrophy. Most of them happen to the elderly. Many people know little about the causes of muscle atrophy. Tell you about it today? Central changes 1. Brain-derived muscular atrophy is rare. Common atrophic lesions in the cerebral cortex, especially in the parietal lobe of the cerebral hemisphere in childhood, such as strong development of congenital motor area or occupying lesions and inflammation in the deep part of the cerebral hemisphere, cause muscle atrophy in the corresponding parts of the contralateral body. 2. Muscle atrophy caused by primary spinal cord anterior horn or brain stem motor nucleus and its conduction pathway lesions. For example, motor neuron diseases, including infantile progressive spinal muscular atrophy, adolescent progressive bulbar palsy, familial adolescent spinal muscular atrophy and so on. 3. Neuromuscular atrophy with diffuse lesions in the central nervous system, such as Guam motor neuropathy, spongiform encephalopathy, familial ataxia, chronic progressive chorea, and lobar atrophy. 4. Secondary central nervous muscular atrophy caused by congenital developmental malformation, such as congenital hypoplasia of brain nuclei, syndrome, hydrocephalus, encephalomyelitis, spinal canal insufficiency, spinal cord hypoplasia, delayed syringomyelia, etc. 5. Spinal cord diseases, such as injury, birth injury, spinal cord compression, herpes zoster myelitis and acute polio. Second, peripheral neuropathy is common in injury, inflammation, tumor, degeneration and so on. Myodystrophy can be caused by acute, subacute or chronic denervation. Different causes of peripheral neuropathy determine the form of muscular dystrophy, but it is not its clinical type. The location of peripheral nerve injury determines the characteristics of clinical manifestations of muscular dystrophy, but it does not affect its pathogenesis. For example, injuries and inflammation are mostly acute attacks. It causes acute denervation of muscles, and the hereditary and degenerative onset progresses slowly, leading to chronic denervation and the occurrence of muscle atrophy is also slow. Nerve root injury causes staged muscle atrophy, nerve plexus injury, a group of muscle atrophy, nerve trunk or peripheral nerve injury, leading to local or individual muscle atrophy. 1. Primary or genetically related peripheral nerve diseases, such as progressive peroneal muscular atrophy, hereditary hypertrophic interstitial neuropathy, amyotrophic ataxia, polyneurofibromatosis, hereditary ataxia polyneuropathy, familial hereditary peroneal muscular atrophy, ataxia syndrome, familial recurrent compressive peripheral nerve paralysis, familial recurrent peripheral neuropathy and hereditary interstitial neuropathy. 2. Peripheral nerve injuries, such as spinal nerve laceration and contusion, brachial plexus nerve compression and birth injury, nerve contraction and compression electric injury, radiation injury, burns, etc. 3. Toxic damage of peripheral nerves, including drugs, organic substances, inorganic substances, bacterial toxins, etc. 4. Peripheral neuritis, including infectious, post-infection and allergic diseases, collagen connective tissue diseases and chastity peripheral neuropathy. 5. Others, peripheral neuropathy in metabolic diseases, peripheral neuropathy in malignant diseases and peripheral nerve tumors. The above are the reasons for muscle atrophy. Experts point out that patients must maintain an optimistic and happy mood and distribute their diet reasonably. Combine work and rest to prevent colds and gastroenteritis. This can effectively prevent muscle atrophy. I wish you a speedy recovery. Editor: Xiao Zhang Publishing: Xiao Zhang
