Overview
Multiple sclerosis (MS) is a complex and debilitating disease that affects approximately 2.8 million people worldwide. It is characterized by the immune system's attack on the protective myelin sheath surrounding nerve fibers in the CNS, leading to communication disruptions between the brain and the rest of the body. MS symptoms can vary greatly from person to person, but common symptoms include vision problems, muscle weakness, numbness, fatigue, and difficulty with balance and coordination.MS is not contagious and is not directly inherited, but genetic predisposition can play a role in its development. The exact cause of MS remains unknown, but research suggests that a combination of genetic, environmental, and hormonal factors may contribute to its onset. MS can be classified into four main types: relapsing-remitting MS (RRMS), secondary progressive MS (SPMS), primary progressive MS (PPMS), and progressive-relapsing MS (PRMS).
History/Background
The first recorded description of MS dates back to 1877, when French neurologist Jean-Martin Charcot described a patient with symptoms that would later become known as MS. However, it wasn't until the 1950s that the disease was widely recognized as a distinct medical condition. Over the years, significant advances have been made in understanding the pathophysiology of MS, leading to the development of various treatments and therapies.Key Information
