This medical animation shows how activated T cells cross the blood brain barrier and attack the myelin, which sheaths the axons of neurons. When the myelin is lost, the axons can no longer effectively conduct signals.
The first part of a series of presentation modules, this video is aimed as an introduction towards the awareness of multiple sclerosis within the global community.

Multiple sclerosis (MS) is a neurological inflammatory disease in which the fatty myelin sheaths around the axons of the brain and spinal cord are damaged, leading to demyelination and scarring as well as a broad spectrum of signs and symptoms. Almost any neurological symptom can appear with the disease, and often progresses to physical and cognitive disability.
