What are Multiple Sclerosis symptoms wax and wane?

Answer 1

When Multiple Sclerosis symptoms "wax and wane," we call it "relapsing and remitting." This is the most common form of Multiple Sclerosis: RRMS, or Relapsing Remitting MS. RRMS is identified by distinct periods of disease activity (relapses) followed by longer periods of disease inactivity (remission)

The other forms of Multiple Sclerosis are:

• Primary Progressive MS: This form of the disease is categorized by a distinct lack of relapses and/or remissions. It shows a continual, slow wordening of disease activity. Approximately 10% of MS patients are initially diagnosed as PPMS.
• Progressive Relapsing MS: This relatively rare form of MS is categorized by distinct relapses but no real remissions, and with each relapse, the disease progresses. Only about 5% of MS patients will develop PRMS
• Secondary Progressive MS: This form of the disease is what can come of Relapsing Remitting MS. Untreated, RRMS will normally develop into SPMS in ten years. This form is identical to Primary Progressive MS, except that it is a follow-on condition to RRMS. Although long-term data is not yet available, disease-modifying therapies available today are thought to delay the onset of SPMS

As mentioned earlier, RRMS is the most common form of MS, with approximately 85% of MS patients initially diagnosed in this category.
