Multiple system atrophy

  • Alternative Names

    Shy-Drager syndrome; Neurologic orthostatic hypotension; Shy-McGee-Drager syndrome; Parkinson's plus syndrome; MSA-P; MSA-C


    Treatment

    There is no cure for MSA, and there is no known way to prevent the disease from getting worse. The goal of treatment is to control symptoms.

    Anticholinergic medications may be used to reduce early or mild tremors. Levodopa may improve movement and balance.

    Carbidopa is usually added to Levodopa to reduce its side effects and make it work better. However, for people with MSA the response to medications may be disappointing. Many people respond poorly to treatment with anticholinergics or Levodopa.

    Medications that may be used to treat low blood pressure include:

    • Beta-blockers
    • Fludrocortisone (Florinef)
    • MAO inhibitors
    • Vasoconstrictors (midodrine)
    • Vasopressin

    A pacemaker that is programmed to stimulate the heart to beat at a rapid rate (faster than 100 beats per minute) may increase blood pressure for some people.

    Constipation can be treated with a high-fiber diet and laxatives. Impotence may be treated with drugs that enhance erections.
