An MS relapse is defined as new or worsening neurological symptoms that last at least 24 hours and occur at least 30 days after any previous symptoms. Symptoms develop over days or weeks and then stabilize and improve over weeks or months. Some people may be left with residual problems or complete recovery after a relapse. If new symptoms evolve over days or weeks that are typical of MS, it is likely a relapse. If old symptoms recur or longstanding symptoms vary daily or last only a few hours, it is less likely a relapse. When experiencing symptoms, contact your MS nurse and see a neurologist to determine if treatment is needed.
