Multiple sclerosis

MS; Demyelinating disease

Multiple sclerosis is an autoimmune disease that affects the brain and spinal cord (central nervous system).

Multiple sclerosis

Multiple sclerosis is a central nervous system disorder marked by decreased nerve function with initial inflammation of the protective myelin nerve covering and eventual scarring. Symptoms and severity of symptoms vary widely and may progress into episodes of crisis alternating with episodes of remission.

MRI of the brain

An MRI (magnetic resonance imaging) of the brain creates a detailed image of the complex structures in the brain. An MRI can give a three-dimensional depiction of the brain, making location of problems such as tumors or aneuryms more precise.

Central nervous system and peripheral nervous system

The central nervous system is comprised of the brain and spinal cord. The peripheral nervous system includes all peripheral nerves.

Myelin and nerve structure

Myelin is the layer that forms around nerve cells. Its purpose is to speed the transmission of impulses along nerve cells.
