Molecular sensor detects early signs of multiple sclerosis, study finds

For some, the disease multiple sclerosis (MS) attacks its victims slowly over a period of years. For others, it strikes in fits and starts. But all patients share one thing: the disease had long been present in their nervous systems, under the radar from the most sophisticated detection methods. But now, scientists have devised a new sensor that can detect MS at its earliest stages -- even before the onset of physical signs.
