Detailed explanation-1: -Multiple sclerosis (MS) is an autoimmune disease of the central nervous system (CNS) characterized by chronic inflammation, demyelination, gliosis, and neuronal loss. The course may be relapsing-remitting or progressive in nature. Lesions in the CNS occur at different times and in different CNS locations.
Detailed explanation-2: -Multiple sclerosis (MS) is the most common demyelinating disease of the central nervous system. In this disorder, your immune system attacks the myelin sheath or the cells that produce and maintain it. This attack causes inflammation and injury to the nerve sheath and ultimately to the nerve fibers that it surrounds.
Detailed explanation-3: -Multiple sclerosis is a disease that affects the central nervous system (brain, spinal cord and optic nerves). It is an autoimmune disease that causes your immune cells to mistakenly attack your healthy nerve cells.
Detailed explanation-4: -Myelin and the immune system The term multiple sclerosis refers to the distinctive areas of scar tissue (sclerosis-also called plaques or lesions) that result from the attack on myelin by the immune system. These plaques are visible using magnetic resonance imaging (MRI).
