  2. Muscular Dystrophy • Serious types of certain muscle diseases, which weakens skeletal muscles. The skeletal muscles are what hold the bones of the skeleton together and move the body. • All Types of muscular dystrophy are inherited • Doctors have not yet found a cure for this disease. • The four most common types of Muscular Dystrophy are; Duchenne, facioscapulohumeral, limb-girdle, and myotonic

  3. Duchenne Muscular Dystrophy • This is the most common and most rapidly progressive muscle diseases. • The first sign is trouble walking at an early age, between two and six years old. • Doctors use antibiotics and flu shots for the lung complications those with who may have problems with their lungs. • Balanced nutrition for overall health can extend the life expectancy for the patients.

  4. Duchenne dystrophy is inherited as an X-linked recessive gene abnormally, it usually affects only boys. • A protein called dystrophin, whose absence in muscle tissue causes the disease.

  5. Myotonic Muscular Dystrophy • Adult dystrophy is the most common. • Symptoms: • Myotonia (Sniffles) • Slowly progressive muscles, weakness in arms, hands, and fingers, feet, and lower legs. • Eye cataracts, diabetes, and weakening of the heart muscle. • Dominant gene abnormally (Women and Men)

  6. Facioscapulohumeral and Limb-girdle Muscular Dystrophy • These types of muscular dystrophy are usually evident in the adolescence or early adult life and are slowly progressive • Facioscapulohumeral Dystrophy primarily affects the muscles of the face, shoulder, and upper arm. • It is inherited as a dominant gene. • Limb-girdle is a recessive gene. • This type affects the muscles of the arms, shoulder, legs and hips.

  7. Muscular Dystrophy Characteristics • Lies on one chromosome of a pair (Chromosome 19) • Grows bigger per generation

  8. How is it diagnosed? • It’s diagnosed through a physical exam, a family medical history, and tests. • Tests include: • A muscle biopsy • DNA (genetic) testing • Electromyography or nerve conduction tests • Blood enzyme tests

  9. Causes • Muscular dystrophy is causes by incorrect or missing genetic information that prevents the body from making the proteins. • It is a defected gene located on the X-chromosome

  10. What causes muscular dystrophy? • It is a genetic disease most likely carried by the X- chromosome.

  11. Is it preventable? Muscular dystrophy is notpreventable since is carried by genetics.

  12. Treatments • Physical therapy • Medications • Assistive devices -Braces, Canes, Walkers, etc • Surgery
