Multiple Sclerosis, or MS, is a degenerative disease of the central nervous system. It causes the destruction of the myelin sheath of nerve fibres. The myelin sheath is made up of protein and fatty substances. It insulates our nerve fibers both in the central and peripheral nervous systems, and has many other duties. The myelin around the nerve fibers prevents the conduction of electrical impulses. Between myelin cells, there are nodes which allows the conduction of pulses. These are called the
Nodes of Ranvier. Instead of all the Sodium/Potassium channels opening one after another along the nerve, only the ones that located at the node will open. This is called saltatory conduction because the propagation of the action potential travels through

Just a sample of that long list of symptoms includes fatigue, walking difficulties, difficulty swallowing, numbness, feeling weak, vision problems, muscle spasms, and dizziness/vertigo (Kister et al,
2013). It makes sense that most of these issues are because of a lack of having control over your body. MS is a reiteration of the fact that having the brain be connected to the body is essential for our survival and essential for a good quality of life. The way doctors and neuropsychologists diagnose MS requires careful consideration of patient history as well as many neurological examinations and tests. These may include MRI, spinal fluid analysis, and blood tests. Since the exact cause of MS is still unknown, there is no known prevention.
Multiple Sclerosis affects women more than men, and the disorder is most commonly found in those between ages 20 - 40, but it can be seen at any age. There are more than 400,000 cases in the United States alone, and more than 2.5 million worldwide (Polman et al, 2010). Interestingly, there has been a pattern that

When learning about any disease or malfunction in human pathology, a common first question is what is the cause of this condition? In the case of Multiple Sclerosis, this is a tough question to answer. Simply put, the cause of multiple sclerosis is unknown.
It's considered an autoimmune disease in which the body's immune system attacks its own tissues (Brassington et al, 1998). Researchers work every day to continue to get closer to finding the cause of Multiple Sclerosis, so that we can then find a way to treat it and help those who suffer from it. From the research outcomes we have seen so far, it seems that MS has genetic, environmental, and immunologic variables (Brassington et al, 1998). There have also been many interesting proposals in what the underlying cause of MS was. These possible explanations include a slow-acting virus, a delayed reaction to a common virus, or an autoimmune reaction to something which causes the body to attack its own tissues (Brassington et al, 1998). None of those possibilities have
been confirmed undeniably yet, so in the research community, the race to find a cause, and then a cure, is still very much
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
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 (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
The causes for multiple sclerosis is unknown. It is an auto immune disease, which the immune system of the body attacks its own tissues. Multiple sclerosis is caused by damage of the myelin sheath. When the nerve covering is damaged, the nerve signals stops or slows down. The inflammation is caused by a nerve damage. This occurs in any region of the brain, optic nerve, and spinal cord. Women are more affected than men. Commonly diagnosed between ages 20 and 40, but it can be seen at any age.
Thesis: Multiple sclerosis brings daily challenges to whomever struggles with it, but with the right team of doctors and medication, it can be maintained.
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, 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.
Tests that help diagnose multiple sclerosis are blood tests, lumbar puncture, evoked potential tests, and a MRI. There is no cure for this disease, but there are some treatments. Treatments that help are
Multiple sclerosis, also known as MS, is an autoimmune and inflammatory disease that is very painful for both the patient and care giver. In the disease, there is inflammation and neurodegeneration acting at the same time. There is currently no known primary cause of multiple sclerosis. The disease is however characterized by damaged fatty myelin sheaths around the axons of the brain and the spinal cord. Myelin is a mixture of proteins and phospholipids that protects many nerve fibers enabling speed at which impulses are conducted. It is pathologically characterized as the presence of glial scars all over in the central nervous system. The disease was discovered by the French neurologist Jean-Martin Charcot in 1868 when he examined the brain
Multiple Sclerosis, a.k.a MS, is a disease of the central nervous system that interrupts messages that go between the brain and the body. The central nervous system is composed of the brain, optic nerves, and spinal cord; it controls functions of the mind and body such as thoughts and body movement. In MS the body's immune system destroys the Myelin Sheath and the nerve fibers. The Myelin Sheath is the protecting cover that surrounded by the nerve fibers. If the Myelin Sheath or nerve fibers are damaged then the nerve impulses in the central nervous system are compromised. Demyelination is the damaging of the Myelin Sheath, afterward a plaque, which is a hardened patch of tissue, forms over the harmed area. This disruption of nerve
Taking correct images for diagnosing Multiple Sclerosis is important. The brain, spinal cord and eyes are the three main areas to scan for the diagnosis to be made. When imaging the brain in axial view, only the outside of the skull is seen along with the brain and sinuses. In a
Multiple sclerosis, also known as MS, is one of humankind’s most mysterious diseases. No one knows the exact cause and there is no exact treatment. Still multiple sclerosis has the ability to affect nearly 3 million people worldwide and at least 500,000 people in the United States (Boroch). This disease tends to be more common in individuals of northern European descent and women are more than twice as likely to develop multiple sclerosis as men. Of those 3 million people, most of them are between the ages of 20 and 50 years old (Dangond). Even though multiple sclerosis is a mystery disease, scientists are working to determine the exact cause and treatment.
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.
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).
