The central nervous system (CNS) is the part of the nervous system that includes the brain and spinal cord. There are two types or divisions of the nervous system. The CNS and the peripheral nervous system (PNS). The PNS connects the CNS to sensory organs, other organs of the body, glands, muscles, and blood vessels. The peripheral nerves include:
- 12 cranial nerves
- Spinal nerves and roots
- Autonomic nerves (the nerves that regulate the heart muscle, glands, and the blood vessel walls.
Multiple sclerosis (MS) can be thought of as an inflammatory process involving different areas of the central nervous system (CNS) at various points in time. Early symptoms of multiple sclerosis include visual changes, difficulty maintaining balance, vertigo, painful muscle spasms, constipation, and urinary retention.
There is no cure for multiple sclerosis, but there is treatment for MS and its symptoms that include medications and therapy.
