Final answer:
Multiple Sclerosis (MS) is an autoimmune disease of the CNS that causes the destruction of myelin, leading to various neurological symptoms and no known cure.
Step-by-step explanation:
Multiple Sclerosis (MS) is a disease that gradually destroys the myelin sheaths of neurons in the CNS (Central Nervous System), particularly in young adults. MS is a neurodegenerative disorder characterized by autoimmune attacks against the central nervous system, specifically targeting myelin, which insulates nerve fibers and facilitates efficient signal transmission.
Patients with MS experience a wide array of symptoms, including fatigue, vision problems, muscle weakness, and difficulty with coordination and balance. The progression of MS can lead to permanent neurological damage, although some functions may be relearned through neural plasticity. Despite ongoing research, there is currently no known cure for this debilitating condition.
