What is Multiple Sclerosis?
  • Multiple Sclerosis (MS) is an acquired
    inflammatory demyelinating disease of the CNS
    (brain and spinal cord).

How Common is MS and Who Gets It?
  • 8,000 10,000 new cases are diagnosed annually
  • Affects nearly 500,000 individuals in the U.S.
  • Occurs most frequently between ages 25 - 35
  • Affects women 2 to 3 times as often as men
  • More frequent in populations native to areas
    further away from the equator
  • Prevalence of MS in KSA is 4-8 cases per 100,000

7
What Causes MS?
  • Unknown
  • Genetics
  • Environmental factors

8
Not Everyone with a Genetic Risk Will Develop MS
Why?
  • Risk is modified by Environmental factors
  • Sunlight
  • Diet (e.g., vitamin D)
  • Other lifetime experiences (infections?)

Initial Presentation of MS
Incidence ()
Optic nerve inflammation 1429
Poor balance (ataxia) 218

10
Other Common Symptoms of MS
Fatigue
Spasticity
Sexual dysfunction
Cognitive impairment Generally occurs later in the disease

12
How Is MS Diagnosed?
  • At least two episodes of symptoms
  • Occur at different points in time (DIT)
  • Result from involvement of different areas of the
    central nervous system (DIS)
  • Absence of other treatable causes for the
    symptoms
  • Results of neurological testing

13
Examples of MS Onset
  • Case 1 26 year old woman
  • Decreased vision in the right eye in 9/05
  • Left leg numbness in 1/06
  • Right face numbness, right arm and leg weakness
    in 4/06
  • Left leg weakness in 8/06
  • Case 2 45 year old man
  • Left arm weakness in 2/93
  • Numbness below the waist in 4/07

14
How Is MS Diagnosed?
  • Magnetic resonance imaging (MRI)
  • CSF
  • slight mononuclear pleocytosis or elevated in
    protein
  • Increase IgG ( elevated IgG index OR the presence
    of oligoclonal IgG bands )
  • Visual evoked potentials

The 2010 McDonald Criteria for Diagnosis of MS
17
How is MS Treated and Managed?
  • Drug therapy
  • Treat new attacks (exacerbations)
  • Prevent the occurrence of future attacks
  • Slow or prevent disease progression
  • Treat the chronic symptoms of the disease
  • Physical therapy
  • Psychosocial support

18
Treatment of New MS Exacerbations
  • Drug therapy
  • Corticosteroids
  • Intravenous immunoglobulin
  • Plasma exchange
  • Physical therapy

19
Prevention of Future Attacks and Disease
Progression
  • Immune modulating drugs
  • Beta-Interferon
  • Glatiramer acetate
  • Humanized monoclonal antibodies
  • Immunosuppressant drugs
  • Anti-cancer agents
  • Combination therapies

20
Symptom Management Examples
Symptom Drug
Spasticity Baclofen
Trigeminal neuralgia Dysethesias Carbamazepine
Bladder Hyperactivity Anti- Cholinergics ( oxybutynin )
Urinary retention Cholinergics ( Bethanechol )
Fatigue SSRI ( fluoxetine )

Summary
  • MS is a common inflammatory disease of the CNS
    that affects females more frequently than males.
  • The cause of MS appears to be a combination of
    genetic and environmental factors.
  • The symptoms of MS can be quite variable.
  • MRI is a sensitive test for making the diagnosis
    of MS.
  • Treatments are available for reducing the number
    of MS attacks and for slowing MS disease
    progression.
