Early Warning Signs of Multiple Sclerosis Syndrome.
Radiologically isolated syndrome (RIS) is a possible precursor to multiple sclerosis (MS) where people show similar lesions on the brain or spinal cord but don't have MS symptoms. Being male, younger, and having lesions on the spinal cord poses an increased risk of developing MS in five years. There is no cure for RIS, but vitamin D supplements, preventing metabolic disorders, and quitting smoking have been linked to a reduced risk of MS. Clinical trials are underway looking for ways to treat the progression of RIS using medications such as teriflunomide, dimethyl fumarate, and ocrelizumab.
