MRI May Predict MS Before Symptoms

A brain scan may show signs of multiple sclerosis years before symptoms occur, a study has found. But not everyone with abnormal brain areas developed MS symptoms. The study included 44 people. All of them had magnetic resonance (MRI) scans of the brain for a variety of reasons. Doctors noticed abnormal areas in the brain like those seen in MS. They kept track of the people for 5½ years. In that time, about one-third developed MS symptoms. One-third developed additional abnormal areas, but had no symptoms. The study was published December 10 in the journal Neurology. USA Today and HealthDay News wrote about it.
