What kind of MS do I have?

Make sure to ask your doctor this question.  There are four main types of MS:

(1) Relapsing Remitting is defined by periods of exacerbation followed by periods of remission and recovery. (The majority of MS patients experience this form of the disease.)

(2) Primary Progressive is defined by chronic disease activity with no distinct remissions although there may be temporary plateaus or minor relief from symptoms.

(3) Secondary Progressive is defined as a relapsing and remitting pattern that later turns into primary progressive.

(4) Progressive relapsing is a rare form of the disease where a patient has chronic activity that also has marked periods of acute exacerbation.

In addition, 20 percent of the MS population has a benign form of the disease in which symptoms show little or no progression after the initial attack; these patients remain fully functional. A few patients experience malignant MS, defined as a swift and relentless decline resulting in significant disability or even death shortly after disease onset. However, MS is very rarely fatal and most people with MS have a normal life expectancy. (Source: National Institute of Neurological Disorders and Stroke)
