Clinical Information
  • 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.
  • 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.
  • 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)
  • 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.
  • 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 body attacks itself. 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 cure for ms, but medicines may slow it down and help control symptoms. Physical and occupational therapy may also help.
ICD-10-CM G35 is grouped within Diagnostic Related Group(s) (MS-DRG v36.0):
