Neurons Can Re-Grow in Some MS Lesions

... The study included nine people with multiple sclerosis (MS) and a control group of four healthy people. In MS, the immune system destroys the myelin sheaths that surround and protect nerves. When the myelin is destroyed, the nerves misfire, and nerve impulses can be slowed or disrupted. The researchers ...
