There is no test to confirm progressive MS. Instead, this diagnosis is based on monitoring how your MS progresses. This is done by recording a description of how your symptoms have evolved over time together with measuring changes on your neurological exam (your exam is graded according to the EDSS score). Perhaps surprisingly, other tests such as MRI scans or spinal fluid exams do not indicate the phase of your MS. It is important that you let your doctor know if you’ve noticed changes in your level of functioning. Whether or not such changes represent progression of your illness, discussing them with your doctor will help you to develop the best health care strategy possible.
