Among the primary features of MS, CNS lesions have far reaching consequences. These are attributable to multiple sclerosis’ CNS demyelinating effect. MS is characterized by the demyelination and inflammation of the nerve cells. The resulting lesions can cause problems in different parts of the body because nervous tissue plays a part in regulating all the organs and organ systems in the patient’s body.

Technically speaking, the CNS or central nervous system constitutes the brain and the spinal cord, which are protected by the blood-brain barrier, skull and spine. (Some medical scientists define the CNS more expansively, adding to the basic definition above the retinas and cranial nerves.) In addition to the central nervous system there is a peripheral nervous system, which includes the nerves and ganglia (“relay points”) beyond the brain and spinal cord. The PNS connects the CNS to the organ systems and extremities of the body. Unlike the …
