1. What is the disease classification?Chronic, inflammatory, demyelinating autoimmune disease of the central nervous system
2. What is the primary target?Myelin sheath and oligodendrocytes in the brain and spinal cord
3. Why do people with MS feel tired or have trouble seeing?When the myelin is damaged, the signals that travel along nerves get slowed or blocked, which can cause tiredness, vision problems, and other symptoms.
4. How do doctors find out if someone has MS?Doctors look for MS by using MRI scans that show plaques in the white matter of the brain and spinal cord, and they also check the immune system for clues.

Central Nervous System (CNS): The brain and spinal cord, responsible for processing information and controlling bodily functions.
Myelin Sheath: An insulating layer around nerve axons that facilitates rapid and efficient signal transmission.
Oligodendrocytes: Glial cells in the CNS that produce myelin.
Demyelination: The loss or damage of the myelin sheath, impairing nerve function.
