A diagnosis of MS is not a death sentence. Multiple sclerosis is not fatal, except in very rare circumstances. During advanced stages of disease progression, it is possible to die from complications related to MS (such as infections or pneumonia). However, that is far from common.

How long can someone live with MS?

MS itself is rarely fatal, but complications may arise from severe MS, such as chest or bladder infections, or swallowing difficulties. The average life expectancy for people with MS is around 5 to 10 years lower than average, and this gap appears to be getting smaller all the time.

Is MS a terminal illness?

So is MS a terminal illness? No, it isn't classed as a terminal illness. It is a life long condition because there is no cure so far. It is a condition where treatments exist but where much better treatments are needed.
