  • 1. Multiple Sclerosis Evelyn Arroyo Mr. Holley Human Interaction Spring 2011
  • 2. Definition
    • “ Multiple sclerosis (MS) affects the central nervous system, which includes the brain and the spinal cord.”
    • (Marshall Brain)
  • 3. Why is myelin important?
    • “ In Multiple Sclerosis, the immune system attacks
    • myelin --the protective coating on nerve cells. Without the protective coating, nerve cells have difficulty doing their job and sending signals.”
    • (Marshall Brain)
    • “ Disruption of communication
    • between the brain and other parts
    • of the body prevent normal passage
    • of sensations and control
    • messages ”
    • ( The Gale Encyclopedia of Medicine)
  • 4. Symptoms
    • the symptoms of MS vary widely from person-to-person and from stage-to-stage of the disease. Initial symptoms often include:
    • Muscle weakness, causing difficulty walking
    • Loss of coordination or balance
    • Numbness, "pins and needles," or other abnormal sensations
    • Visual disturbances, including blurred or double vision.
    • Later symptoms may include:
    • Fatigue
    • Muscle spasticity and stiffness
    • Tremors
    • Paralysis
    • Pain
    • Vertigo
    • Speech or swallowing difficulty
    • Loss of bowel and bladder control
    • Incontinence, constipation
    • Sexual dysfunction
    • Cognitive changes.
    • Weakness in one or both legs is common, and may be the first symptom noticed by a person with MS. Muscle spasticity, or excessive tightness, is also common and may be more disabling than weakness.
  • 5. Long-life Effects
    • “ The damage that MS causes can affect:
    • --the eyes, which have thousands of nerve fibers to carry visual Information from the retina to the brain, as well as nerve cells controlling the eye's muscles
    • --muscle coordination and strength, because nerve fibers have direct control of all muscles
    • --speech, which is controlled by muscles in the throat, mouth and tongue
    • --bladder and bowel control”
    • (Marshall Brain)
  • 6. Assistance/Treatments
    • there are three drugs approved for the treatment of multiple sclerosis which have been shown to affect the course of the disease. None of these drugs is a cure, but they can slow disease progression in many patients.
