Multiple sclerosis (MS) is the most widespread disabling neurological condition of young adults around the world. You can develop MS at any age, but most people receive diagnoses between the ages of 20 and 50.
There are relapsing, remitting, and progressive types of MS, but the course is rarely predictable. Researchers still don’t fully understand the cause of MS or why the rate of progression is so difficult to determine.
The good news is that many people living with MS don’t develop severe disabilities. Most have a normal or near-normal lifespan.
