Myopathies can be broadly classified into several categories based on their etiology and histological features:
Genetic Myopathies: Includes muscular dystrophies (e.g., Duchenne Muscular Dystrophy), myotonic dystrophies, and congenital myopathies. Metabolic Myopathies: Result from defects in muscle metabolism, such as glycogen storage diseases and mitochondrial myopathies. Inflammatory Myopathies: Characterized by autoimmune-mediated muscle inflammation, including polymyositis, dermatomyositis, and inclusion body myositis. Toxic Myopathies: Caused by exposure to toxins, drugs (e.g., statins), or other environmental factors. Endocrine Myopathies: Associated with hormonal imbalances, such as hypothyroidism or hyperthyroidism.
