2-Minute Neuroscience: Multiple Sclerosis

In this video, I discuss multiple sclerosis. Multiple sclerosis is a central nervous system disorder that can create a variety of symptoms ranging from visual disturbances to paralysis. It is characterized by damage to myelin, the insulatory material that surrounds neurons. This damage is linked to disruptions in healthy neuronal function, which are thought to lead to the symptoms of the disease. It is widely believed that the myelin damage that occurs in multiple sclerosis is due, at least in part, to the cells of the immune system targeting myelin. Thus, most of the treatments for multiple sclerosis involve drugs that suppress the immune response in some way.
