How long can MS go into remission? I was diagnosed in 2008 but my 2013 MRI shows no major progression?
On average, MS patients have clinical relapses and MRI lesions throughout the course of the disease. The frequency and rate varies from patient to patient, but in general lesions and relapses are more frequent early in the course of the disease. Based on natural history studies, it is estimated to expect anywhere from 5 to 10 new lesions every 18 months in the first 10 to 15 years of the disease, and of those lesions, 1 out of 10 will likely cause symptoms (relapses). These numbers are estimates and is a generalization based on large number of patients. In general terms, the longer the time patient goes without new lesions/relapses, the better the prognosis.
