Muscular Dystrophy
Moderate
Muscular dystrophy is a group of inherited disorders characterized by progressive muscle weakness and loss of muscle tissue. More than 30 types are recognized, and they differ in the muscles affected, age at onset, rate of progression, and involvement of other organs. Some forms begin in childhood while others become apparent later in life. Depending on the type, weakness can affect walking, daily activities, breathing, swallowing, or heart function.

When to Seek Medical Attention
Muscular dystrophy requires ongoing medical care because muscle weakness can gradually progress and some forms can affect breathing, swallowing, or the heart. Seek prompt medical assessment for worsening weakness, falls, swallowing difficulty, or reduced mobility. Urgent evaluation is appropriate for significant breathing difficulty, choking, chest symptoms, or sudden major deterioration.

Causes 1
Muscular dystrophies are caused by inherited genetic changes that interfere with proteins needed for normal muscle structure and function. Different forms involve different genes and inheritance patterns. Examples include Duchenne, Becker, facioscapulohumeral, limb-girdle, myotonic, and oculopharyngeal muscular dystrophies. A person may inherit the condition from a parent, or in some circumstances a genetic change may arise without a previously recognized family history.
Genetics
Risk Factors
The principal risk factor is having a genetic change associated with a muscular dystrophy. Risk therefore depends on the specific type and its inheritance pattern. A family history of muscular dystrophy or unexplained progressive muscle weakness can be important when assessing risk. Because some forms have sex-linked inheritance while others follow different patterns, genetic counseling may be useful for affected individuals and families considering future pregnancies.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis begins with the pattern of muscle weakness, age at onset, family history, and physical examination. Blood tests may identify increased muscle enzymes. Genetic testing can identify disease-causing variants and may establish the specific type. Electromyography and nerve studies can help distinguish muscle disorders from nerve disorders. Imaging such as MRI can assess muscle quality and fatty replacement. Depending on the suspected disorder, additional heart, breathing, or swallowing assessments may be needed.
Prevention
Key Prevention Tips
Most muscular dystrophies cannot be prevented because they result from inherited genetic changes
Families with a known history may benefit from genetic counseling to understand inheritance and reproductive options
Early recognition is important because treatment and supportive care can reduce complications and maintain function
Physical and occupational therapy, respiratory monitoring, appropriate exercise, assistive devices, and management of heart or other organ involvement can help people remain as active and independent as possible
