Explain about the Multiple Sclerosis
This is a disease characterised by the loss of myelin, largely in motor tracts but also in sensory tracts. The loss of myelin is not uniform, rather, it is lost in patches-small, hard, circumscribed scars, called sclerotic plaques in which the myelin sheath and sometimes the axons are destroyed.
Multiple sclerosis produces strange symptoms that usually appear first in adulthood. The initial symptoms may be loss of sensation in the face, limbs, or body, blurring of vision; or loss of sensation and control in one or more limbs.
