Myopathies are a group of muscle disorders characterized by abnormal muscle structure or function. These conditions can be inherited or acquired and lead to muscle weakness, pain, or stiffness. Myopathies may affect specific muscle groups or the entire body, impacting mobility and daily activities. Causes include genetic mutations, inflammatory processes, or underlying medical conditions. Diagnosis involves clinical evaluations, blood tests, imaging studies, and sometimes muscle biopsies. While treatments may not cure myopathies, they focus on managing symptoms, improving muscle function, and enhancing the overall quality of life for those affected by these muscle-related disorders.
