what is the underlying mechanism of disease in multiple sclerosis
The disease usually begins between the ages of 20 and 50 and is twice as common in women as in men. MS was first described in 1868 by Jean-Martin Charcot. The name multiple sclerosis refers to the numerous scars (scleraeâbetter known as plaques or lesions) that develop on the white matter of the brain and spinal cord. A number of new treatments and diagnostic methods are under development.
