  1. Neuromuscular Dystrophy By: Dana DeGraaf

  2. What is Neuromuscular Dystrophy? • Neuromuscular dystrophy is a term used to refer to a group of muscle disorders in which the face, limbs, heart or spine muscles gradually weaken and shrink over time. • In cases involving the heart and spine, this can be fatal.

  3. Examples: • Duchenne muscular dystrophy • Myotonic dystrophy • Becker’s muscular dystrophy • Distal muscular dystrophy • Limb-girdle muscular dystrophy • Etc…

  4. Here is an example of Muscular Dystrophy

  5. The different types are distinguished by factors such as: • Age at which symptoms start • Pattern of weak muscles • Speed that the disease progresses • Involvement of other tissues besides muscles • Pattern of inheritance

  6. Causes of neuromuscular dystrophy All muscular dystrophies are inherited. Each type is associated with the genetic mutation in the DNA line. A woman who has the mutated gene is called a carrier. Each of her children have a 50% chance of getting her genetic mutation. If her child is a boy, then he will develop the muscular dystrophy. If it is a girl, she will become a carrier and have the 50% chance to pass the disease on to her children.

  7. Signs and symptoms: • Progressive muscle wasting • Poor balance • Scolosis (curved spine) • Limited range of movement • Inability to walk

  8. Effects on the brain: • There have been reports of a 50% decrease in neuron number and neural shrinkage in regions of the cerebral cortex and brain stem. • People diagnosed with neuromuscular dystrophy have been reported to have a lower IQ (average 85)
