How long a patient with muscular atrophy can live needs to be analyzed in relation to the etiology. Most patients with muscular atrophy will not affect their survival, but some patients with muscular atrophy may die within 1-2 years due to respiratory muscle paralysis or lung infection. Muscle atrophy is divided into neurogenic muscle atrophy and myogenic muscle atrophy according to the etiology. Neurogenic muscle atrophy is commonly caused by injuries to the anterior horn of the spinal cord, nerve roots, plexus injuries and peripheral neuropathies. For example, muscle atrophy caused by familiar cervical spondylosis, carpal tunnel syndrome, and sequelae of cerebral infarction are all neurogenic injuries, which have less impact on survival. It is important to note that motor neuron disease, which may involve respiratory muscles, has an impact on survival. In contrast, myogenic muscle atrophy is caused by disease of the muscles themselves, commonly due to myotonic dystrophy, and can shorten survival in some patients if other systems are involved. Therefore, the survival of patients with muscular atrophy cannot be generalized and requires analysis of the specific etiology to make an accurate judgment. When muscle atrophy occurs in patients, it is recommended to actively go to the hospital to improve the relevant examination, clarify the specific cause of the disease and then actively treat it and prevent the occurrence of complications.
