Muscular dystrophies are a group of genetic disorders characterized by progressive weakness and degeneration of the skeletal muscles. These conditions are caused by mutations in genes responsible for muscle structure and function, leading to muscle wasting over time. Symptoms often begin in childhood or adolescence, but some forms can appear later in life. There are several types of muscular dystrophies, including Duchenne muscular dystrophy and Becker muscular dystrophy. Diagnosis typically involves physical examinations, genetic testing, and muscle biopsies. While there is currently no cure, treatments focus on managing symptoms and improving quality of life through physical therapy and medications.
