Understanding Multiple Sclerosis

The video discusses multiple sclerosis (MS), a disease affecting the central nervous system (CNS), including the brain, spinal cord, and optic nerve. It explains how neurons and myelin facilitate signal transmission and how MS disrupts this process through an autoimmune response. The symptoms of MS are diverse, ranging from muscle weakness to paralysis, and diagnosis often involves MRI scans. While the exact cause of MS is unknown, research is ongoing to find treatments and raise awareness. The video is sponsored by 23andMe, a DNA analysis service.
