Multiple sclerosis is an autoimmune disease that involves the different areas of the central nervous system, the brain, and spinal cord. It damages the myelin sheath, the material that surrounds and protects the nerve cell. This damage slows down and blocks messages between the brain and body, leading to the symptoms of Multiple sclerosis. Which includes Visual disturbances, Muscle weakness, and Trouble coordinating balance, sensations such as numbness, prickling, and thinking and memory problems? No one knows the causes of Multiple sclerosis; they think it might be an autoimmune disease, which happens when the body attacks itself. Usually, the disease is mild, but some people lose the ability to write, speak, or walk.
MS is considered an immune-mediated disease. That is, the immune system malfunctions and attacks the CNS. Researchers know that the myelin sheath is directly affected, but they don’t know what triggers the immune system to attack the myelin. Research about which immune cells are responsible for the attack is ongoing. Scientists are seeking to uncover what causes these cells to attack. They’re also searching for methods to control or stop the progression of the disease. Several genes are...

...ill continue to function in an abnormal way as described above, but the axon remains undamaged. Sometimes after a long period of time, sometimes years, an axon will spontaneously become demyelinated and regain much of the function that had been presumed to be lost for good. The lost myelin can be replaced with scar tissue much like when you cut your hand a scar forms to join the separated areas of skin. This scarification is how Multiple Sclerosis got its name: Multiple - many and Sclerosis - scar forming. Scar tissue can block the formation of new myelin and once axons have become scarified they do not fully regain their former function. The underlying axon can become withered and function lost entirely. Needless to say a withered axon will never function at all again. Continuing our electrical wire analogy, this is rather like snipping the cable with wire cutters.

- Currently there are more than 2.5 million individuals living with Multiple Sclerosis (MS) worldwide (5). MS is an autoimmune disease characterized by the destruction of the myelin sheath and the interruption of nerve impulses throughout the brain and spinal cord, culminating in the loss of physical and cognitive function (5). Being that MS is so complex and multifaceted means the attitude towards study needs to be both meticulous and comprehensive. The approach to MS research is twofold as it focuses on developing an understanding of the evolutionary factors and etiological mechanisms that have contributed to the intricate nature of the disease thus encouraging the development comprehensive...

- Introduction Multiple Sclerosis (MS) is a debilitating autoimmune disease. The Central Nervous System (CNS) is attacked by the immune system; creating lesions that interrupt the correct signaling of nerves, spinal cord, and brain (Frankel, & James, 2011). Inhibiting development of this disease is crucial for maintaining quality of life and fatigue for individuals with MS. There has been vast amount of research on the effect of various exercise training programs, and their benefits for MS (Motl, & Gosney, 2008, Krupp, 2003, Chen, Fan, Hu, Yang, & Li, 2013)....

- Steeno Burris HPE 110-A Multiple Sclerosis Implications and Treatment In the US, the number of people with Multiple Sclerosis is estimated to be about 400,000, with approximately 10,000 new cases diagnosed every year. Sclerosis is defined as “a hardening or induration of a tissue or part, or an increase of connective tissue or the like at the expense of more active tissue.” Multiple Sclerosis (MS) is an autoimmune disease that affects the Central Nervous System. With an autoimmune disease, the body’s immune system mistakenly attacks its own tissue and organs.... [tags: Multiple sclerosis, Nervous system, Symptoms]

- Introduction Multiple sclerosis is an autoimmune disease that majorly affects the brainand the spinal cord (A.D.A.M. Medical Encyclopedia, 1). The disease affects the central nervous system and thus causes limitations of individuals to carry out various activities. In multiple sclerosis, the myelin sheath that covers nerve cell axon is destroyed causing inflammation (MediResource Inc., 1). Destructionof the membrane leads to slowed conveyance of signals from the spinal cord to the brain, which as a result leads to reduced response to different stimuli....

- Introduction According to National Multiple Sclerosis Society, Multiple Sclerosis (MS) is an unpredictable, often disabling disease of the central nervous system (CNS) that disrupts the flow of information within the brain, and between the brain and body. The central nervous system (CNS) comprises of the brain and the spinal cord. CNS is coated and protected by myelin sheath that is made of fatty tissues (Slomski, 2005). The inflammation and damage of the myelin sheath causing it to form a scar (sclerosis).... [tags: Multiple sclerosis, Nervous system, Neuron]

- The Multiple Sclerosis Association of America (MSAA) is the main organization that works toward improving the lives of United States citizens with the disease. Being a nonprofit organization, MSAA mainly relies on money and other resources it receives from donors and well-wishers to fund its operations. To increase the amount of donations it receives, the organization requires a well-designed case for support to persuade and encourage more donors to come on board. Without MSAA, the lives of most individuals with MS in the country would deteriorate given the fact that most of them depend on the subsidized medical services they get from the organization....

- Multiple sclerosis is a chronic disease that involves the immune system improperly attacking healthy tissue in one’s central nervous system. Ignatavicius and Workman (2013) describe that this autoimmune disease produces inflammation in the central nervous system, progressively destroys myelin sheath, impairs the conduction pathway of neurons in the central nervous system, and causes plaque formation in the white matter. The destruction of the myelin sheath and formation of plaque in the white matter cause a variety of symptoms.... [tags: Multiple sclerosis, Nervous system]

- Imagine, 324,118,787 people in the world. Out of those individuals, approximately 2.5 million people are diagnosed with this disease, and more than 400,000 people in the United States suffers from this disease. About 200 people in the United States are diagnosed with this disease weekly (Pietrangelo). The name of this disease is called Multiple Sclerosis. “Multiple sclerosis, or MS, is a long-lasting disease that can affect your brain, spinal cord, and the optic nerves in your eyes. It can cause problems with vision, balance, muscle control, and other basic body functions” (“What is Multiple Sclerosis?”).... [tags: Multiple sclerosis, Nervous system, Myelin]

- Multiple Sclerosis (MS) is a common neurological condition that has been present throughout the world for many years, yet there is still a lot of information about this disease that is unknown. There is currently no absolute cause of MS, which presents a challenge to discover a cure as well. However, there are many treatments, including physical therapy, available to help manage the symptoms of this disease. MS is a disease that is characterized by the demyelination of axons throughout the central nervous system.... [tags: Multiple sclerosis, Nervous system, Brain]

- Multiple sclerosis (MS) is a disease of the central nervous system (CNS). It is considered an autoimmune response because the immune system attacks the myelin sheets of CNS. These attacks can take place anywhere in the brain and spinal cord. The results are areas of hardening in the myelin sheets which unable the communication of nerve impulses to their designated locations. As consequences of the malfunction of the myelin sheets the nervous systems slows down in response to stimuli.
