    3. U.S. Total: 250,000-350,000 patients affected

III. Pathophysiology

  1. Acute attacks (relapsing remitting MS) are a result of inflammatory reaction
    1. Inflammatory cells (T Cells, B Cells and Macrophages) cross the blood-brain barrier at weakened vessel surfaces
    2. Immunoglobulins target the Myelin Sheath
    3. Macrophages damage the axons with free radical release
  2. Results
    1. Focal regions of demyelination of white matter
    2. Particularly periventricular and subpial white matter

IV. Prognosis

Ontology: Multiple Sclerosis (C0026769)

Definition (MEDLINEPLUS)

Multiple sclerosis (MS) is a nervous system disease that affects your brain and spinal cord. It damages the myelin sheath, the material that surrounds and protects your nerve cells. This damage slows down or blocks messages between your brain and your body, leading to the symptoms of MS. They can include

  • Visual disturbances
  • Muscle weakness
  • Trouble with coordination and balance
  • Sensations such as numbness, prickling, or "pins and needles"
  • Thinking and memory problems

No one knows what causes MS. It may be an autoimmune disease, which happens when your immune system attacks healthy cells in your body by mistake. Multiple sclerosis affects women more than men. It often begins between the ages of 20 and 40. Usually, the disease is mild, but some people lose the ability to write, speak, or walk.

There is no single test for MS. Doctors use a medical history, physical exam, neurological exam, MRI, and other tests to diagnose it. There is no cure for MS, but medicines may slow it down and help control symptoms. Physical and occupational therapy may also help.

NIH: National Institute of Neurological Disorders and Stroke

Definition (MSHCZE) Chronické onemocnění CNS charakterizované demyelinizací. Postihuje osoby spíše mladšího a středního věku. Příčina onemocnění není známa, k teoriím patří účast neznámého viru a autoimunitní poškození, existuje asociace s některými antigeny HLA systému. Příznaky r. s. závisejí na poškozeném místě v nervové soustavě a mohou být velmi pestré – spinální, cerebrální, cerebelární poruchy chůze, citlivosti, řeči, močení, ataxie, obrny aj.. Úvodním příznakem často bývá retrobulbární neuritida zrakového nervu. Mohou být i psychické příznaky např. deprese, ale i euforie. Průběh nemoci je kolísavý, střídají se období klidu s náhlými zhoršeními. Ta jsou často vyprovokována i běžným onemocněním. Těžký průběh nemoci může vést až k invaliditě. V diagnostice se uplatňuje vyšetření likvoru, evokované potenciály, zobrazovací metody. Zkouší se řada léčebných postupů, ale žádný zatím nedokáže nemoc vyléčit. Používají se např. kortikoidy, imunosupresiva, interferon, významná je i fyzioterapie a rehabilitace. (cit. Velký lékařský slovník online, 2013 http://lekarske.slovniky.cz/ )
Definition (NCI_NCI-GLOSS) A disorder of the central nervous system marked by weakness, numbness, a loss of muscle coordination, and problems with vision, speech, and bladder control. Multiple sclerosis is thought to be an autoimmune disease in which the body's immune system destroys myelin. Myelin is a substance that contains both protein and fat (lipid), serving as a nerve insulator and helping in the transmission of nerve signals.
Definition (NCI) A progressive autoimmune disorder affecting the central nervous system resulting in demyelination. Patients develop physical and cognitive impairments that correspond with the affected nerve fibers.
Definition (MSH) An autoimmune disorder mainly affecting young adults and characterized by destruction of myelin in the central nervous system. Pathologic findings include multiple sharply demarcated areas of demyelination throughout the white matter of the central nervous system. Clinical manifestations include visual loss, extra-ocular movement disorders, paresthesias, loss of sensation, weakness, dysarthria, spasticity, ataxia, and bladder dysfunction. The usual pattern is one of recurrent attacks followed by partial recovery (see MULTIPLE SCLEROSIS, RELAPSING-REMITTING), but acute fulminating and chronic progressive forms (see MULTIPLE SCLEROSIS, CHRONIC PROGRESSIVE) also occur. (Adams et al., Principles of Neurology, 6th ed, p903)
Definition (CSP) chronic disease characterized by presence of numerous areas of demyelination in the central nervous system with symptoms such as weakness, incoordination, paresthesis, and speech disturbances; the etiology is unknown.
