Multiple Sclerosis : An Automobile Immune Disease

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 is an unpredictable, potentially disabling disease of the central nervous system that can affect the brain, spinal cord, and nerves. Multiple Sclerosis can range from relatively benign to disabling to devastating. The disease is considered an autoimmune disease in which the body’s immune system attacks its own tissues causing damage to the myelin sheath, which covers the nerve fibers, and causes communication problems between the brain and the rest of the body and ultimately cause the nerves to deteriorate or become permanently damaged. When any part of the myelin sheath is damaged or destroyed the nerve impulses that travel back and forth to the brain and spinal cord are interrupted, this produces a range of different symptoms.

Multiple sclerosis (MS) is an unpredictable, immune mediated disease of the central nervous system (CNS) (Definition of MS). This disease is estimated to affect more than 400,000 people in the United States alone, and about 2.5 million worldwide. In the United States, about 200 new cases of MS are discovered weekly (Pietrangelo, Anne and Higuera, Valencia) . In a healthy person, an insulation covering called myelin, coats the nerve fibers in the CNS (Article from mom). When one develops MS, the communication between their brain and other parts of his/her body is disrupted as “an abnormal immune-mediated response” attacks the myelin coating that encloses nerve fibers in the CNS. This causes a disturbance in communication between the CNS and

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).

It is suggested by previous studies that the damage of the myelin sheath in MS involves the activation of inflammatory factors including the CD4+ T cells, CD8+ T cells, B cells, macrophages and microglia cells (Luccinetti et al., 1996; Lassmannet al., 2012). However, whether the immune response triggers the onset of MS, or is a consequence of the disease process is currently not clear. Interestingly, several recent studies suggested that the prevalence rate of MS is significantly increased with latitude, which implies that not only the geographical (environmental) differences but racial and ethnic differences may play a role in the worldwide MS distribution (Rosati, 2001; Simpson et al., 2011).

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.

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.

Multiple Sclerosis, commonly known as MS is an autoimmune disease of the central nervous system. Scientists have been studying MS since the 19th century. In MS, the body’s immune system produces cells and antibodies that attack myelin in your brain which is essential for the nerves in your brain and spinal cord to conduct electricity to perform its function. The attack on myelin results in vison loss, paralysis, numbness, muscle weakness, difficulty walking, stiffness, spasms, and bladder and bowel problems. MS has varying degrees of severity and affects people between the ages of 20-50, mostly women. Although there are treatments, there is no cause and cure yet.

Multiple Sclerosis, commonly referred to as MS, is an unpredictable disorder of the central nervous system, or CNS, and it is a chronic inflammatory disorder. MS is a disease that involves the immune system attacking the CNS. They myelin that covers and protects the nerve fibers is damaged, as well as the nerve fibers themselves. They myelin that is damaged forms scar tissue know as sclerosis. This is where the name of the disease came from. When the nerve fibers or myelin is damaged, the nerve fibers that travel to and from the spinal cord are distorted or interrupted this is why there is a variety of symptoms that can occur. Multiple Sclerosis affects rather young individuals, as young as twenty. It is most common in adults in their twenties

Multiple sclerosis, or MS as it is more commonly referred, is an immune mediated disease that involves the body's own defense mechanism, specialized immune cells, that ultimately attacks the central nervous system. Specifically, the myelin protein that coats axons and forms an electrically insulating layer for quicker processing of the nervous system, is attacked by cytotoxic cells that have crossed into the CNS. In a healthy patient, the blood brain barrier cannot be crossed by cytotoxic cells and it is speculated that an environmental component or outside source mediates this crossing. When the myelin is attacked, it forms scars in the CNS, as multiple sclerosis literally translates to “many scars,” which is the direct result of the disease. The scars disrupt the normal nerve impulses that travel through the central nervous system, and can cause a variety of symptoms including loss of cognition, fatigue, or numbness in the body (Evidence).

In Multiple Sclerosis, an abnormal immune mediated response attacks the myelin coating around the nerves in the nervous system in the body. They also say that Multiple sclerosis is more prevalent in areas farther away from the equator (National MS Society). The environment may even have a small role in the disease. Scientists also believe that Multiple Sclerosis may happen when exposed to different viruses and bacteria. According to PubMed, Infectious pathogens are the likely environmental factors involved in the development of Multiple Sclerosis (PubMed). Multiple Sclerosis is not a contagious disease at all. It is not a genetic

Moreover, the location of the living place in the world can affect some aspects causing MS to develop, and these aspects are the expose to sunlight and vitamin D concentration in the body (3,5). When people are further away from the equator, they become more in risk to have MS due to decreasing sunlight exposure and vitamin D concentration (5). The relation between sunlight exposure and vitamin D is that sunlight exposure gives the body the essential amount of vitamin D to function properly (3). When Vitamin D concentration decrease, the enzymes that help producing Calcitriol, a substance that helps the brain activate the genes essential for nervous cells to make neurotrophins protein that helps the cells to grow, decrease too causing brain problem
