Multiple Sclerosis Research Paper

Multiple sclerosis (MS) involves an autoimmune process that develops when a previous viral insult to the nervous system has occurred in a genetically susceptible individual. B lymphocytes, plasma cells, and activated T cells, along with proinflammatory cytokines, cause inflammation, oligodendrocyte injury and demyelination. Early inflammation and demyelination lead to irreversible axonal

Multiple Sclerosis (MS) is a neurologic disease that affects the Central Nervous System (CNS) through cellular immune response and the demyelination of CNS white matter (McCance et al., 2014, pp. 630–633). The initial causes of MS are unknown however, it is believed that it could possibly be due to an immune response to an initiating infection or an autoimmune response to CNS antigens on the myelin itself (Brück, 2005) (Miljković and Spasojević, 2013). MS is a result of the degradation of the myelin sheath surrounding neurons and therefore disrupts the transmission of action potentials along these cells. MS can display itself in the form of symptoms ranging from muscle weakness to trouble with sensation and coordination (NHS, 2016). The degradation of myelin leads the body to attempt to remyelinate the neurons, a process that in turn leads to the thickening of the cell by glial cells and this causes lesions to form (Chari, 2007). It is this thickening (sclerae) from which the disease gets its name. Sufferers of MS can either have a relapsing type of MS, in which there are episodes that lead to the worsening of symptoms for a period of time, or a progressive type of MS where symptoms gradually progress and worsen (McCance et al., 2014, pp. 630–633).

The central nervous system (CNS) comprises grey matter, which contains neuron cell bodies and white matter, which contains the nerve axons. Most of the nerve axons are concentrically wrapped around by lipid-rich biological membrane, known as the myelin sheath. In the CNS, myelin is produced by oligodendrocyte. a type of glial cell. (Pfeiffer et al., 1993). These electrical insulating, multilamellar membranes significantly increase the electrical resistance, in which to prevent leakage of electrical currents from the axons, as well as decrease electrical capacitance to reduce the ability of the axons to store electrical energy (Shivane &

Multiple sclerosis is a chronic, progressive neurological disease affecting all aspects of life: physical, cognitive, emotional, and social (Abma). It is known as an autoimmune disease, Where the body’s immune system turns against the body and destroys the protective covering that surrounds nerve cells. This damage to the nerve cells causes many problems for the patient including weakness, muscle stiffness, poor coordination and balance, tingling, numbness, tremors, blurred vision, slurred speech, and memory and concentration problems (Bren)

Multiple Sclerosis (MS) is a chronic inflammatory disease of the central nervous system. MS affects approximately 3.0 million people globally, with about 300,000 cases in the United States. Twice as many women as men have MS. The average ages for onset of MS is 20-40 years. In MS, cells in the immune system attack and destroy myelin, the fatty tissue surrounding nerve cells (http://www.phylomed.com/MS.html). Scar tissue replaces the myelin, interfering with the transmission of nerve signals and leading to numbness, fatigue, spasticity, loss of muscle control, and various other debilitating symptoms. There are four broad theories

Multiple sclerosis, or MS, is a disease of the central nervous system. The central nervous system is made up of the brain and spinal cord. Both have nerve fibers that are wrapped in a myelin sheath. In MS, the myelin sheath becomes inflamed and gradually is destroyed. With the destruction of the myelin sheath comes an array of symptoms that may include numbness or tingling, balance problems, weakness, muscle spasms, and blurred vision.

In the world of neurology, there are a vast amount of neurological disorders, conditions, and diseases. One severe disease is known as Multiple Sclerosis. In this research essay, I will be discussing what multiple sclerosis is, symptoms, causes, personal experience, and treatments.

The difference between having MS and not having it is that your body will not have scars or hardened tissues which effects the CNS. Affecting the CNS is massive as it is your brain and your spinal cord which makes all the decisions for your nervous system and without a fully functioning CNS, the person will have all the effects that was said in the previous paragraph (the effects of MS) which were things like not able to walk properly, numbness and the persons eyesight becoming

Multiple Sclerosis is a disease that attacks the myelin coating over the nerve receptors in your brain and spinal cord. Myelin is a fatty material that coats and protects the nerves in your brain. These nerves send signals to the rest of your body enabling

Multiple Sclerosis (MS) is an autoimmune disease that attacks the central nervous system. The myelinated nerve cells get attacked which results in scars and lesions that destroy the myelin sheath. The reason for the body attacking its own nerve cells is unknown. Many believe that the cause of MS is from a virus, a deficiency in Vitamin D, or genetics. Studies are being done to find out what is the real cause of MS.

Multiple Sclerosis (MS) a disease which the immune system attacks the protective sheath also known as the myelin that covers the nerves. Damages myelin disrupts the communication between the brain and the rest of the body. The nerves itself may weaken, process that is currently irreversible.

The father of neurology, Dr. Charcot, examined the brain of a deceased patient because the patient had a tremor unlike anything he has treated before. He noticed plaques or abnormal clusters of chemically sticky proteins that build up amongst nerve cells. He also described the patient’s symptoms and changes in the brain that accompanied the plaques; this was the first description of multiple sclerosis. In England in 1873 and in the United States in 1878, multiple sclerosis was first recognized based off of Dr. Charcot’s description of the disease. In 1916, Dr. James Dawson performed autopsies on brains of patients who died with multiple

Research shows that interferon reduces the MS relapse rate by one-third over a two-year period. Magnetic resonance imaging (MRI) has shown that patients treated with high doses of beta-interferon have fewer lesions and less scarring on the brain than patients on lower doses or those given placebo treatment. Studies also show that treatment with interferon beta may reduce severity of symptoms and lower the chance of disability in patients who have relapsing remitting MS.

Multiple Sclerosis is an autoimmune disorder where the myelin sheath within the Central Nervous System is attacked (National Multiple Sclerosis Society, 2017). The myelin sheath protects the axon of the nerve cell. When the myelin sheath is intact, the axon is able to carry impulses away from the neuron’s cell body, and the message carried is clear. With Multiple Sclerosis, the myelin sheath becomes scarred, hence the word “sclerosis”, and distorts the nerve impulses traveling over the CNS (National Multiple Sclerosis Society, 2017). This may cause the message to be changed or stopped altogether.

In severe cases, Multiple Sclerosis can break down the nerves themselves. This leads to communication problems within the brain and between the brain and the rest of the body (Mayo Clinic.) The myelin sheath is an insulator- it surrounds and nourishes the axons. Exposing small points called the Nodes of Ranvier. The combination of the nodes and sheath is meant to speed up signal sent by that neuron (Morell, Pierre.) Damage to the sheath, causes the electrical signal to be drastically slowed down, leading to harmful effects in the human body. Symptoms vary widely depending on which nerves the disease affects. Symptoms range from nominal mobility issues to complete dysfunction (Mayo Clinic.) The damaged myelin and nerve fibers are replaced with scar tissue- called sclerosis- which is where the disease gets its name. While many scientists believe Multiple Sclerosis to be an autoimmune disease, the exact proteins that trigger the immune response of MS are unknown. Because of this, the illness is considered to be an immune mediated disease, but this may change in the future (National Multiple Sclerosis Society.)
