Multiple Sclerosis Essay

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.

b. Support: In 2007, it was reported that approximately 2.5 million people in the world have MS.

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)

As a senior this year, I am looking forward to several endeavors, such as leading my team in my last year of cheerleading, participating in a Senior Engineering Design Project, and continuing to volunteer with VSVS, a program that allows Vanderbilt student to teach science lessons in local elementary schools. Moreover, I spent this past summer working on my research at the Vanderbilt Institute of Imaging Science and will continue my projects throughout the school year. I am excitingly close to finishing the project I have been working on that involves a magnetic resonance imaging study of patients with multiple sclerosis. We have employed quantitative magnetization transfer techniques at 7-Tesla field strength to obtain indices reflective

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.

M.S., as some would call it, also known as multiple sclerosis is a neurological disease. This disease, in particular, could also be viewed as an autoimmune disorder. It is not nearly as fatal as the sexually transmitted disease (AIDS), yet it can be just as debilitating. What exactly is Multiple Sclerosis? Multiple sclerosis is a disease in which the immune system malfunctions and begins to attack the myelin sheath. The myelin sheath is an insulating cover

The breakdown of the myelin sheath is caused from a mutation of the gene that makes the Adrenoleukodystrophy protein (ALDP). This ALD protein helps the body metabolize saturated very-long-chain fatty acids found in the serum and tissues of the central nervous system. The newly mutated gene no longer acts as a help aid to breaking down the long-chain fats. Therefore, the body starts accumulating an abnormal amount of fat in the nervous system, adrenal gland and testes that sets off an unusual response in the immune system; demyelination.

MS(Multiple Sclerosis) is a disease which gradually hardens all tissues and also causes scars. These scars form when the persons immune system's cells go into the central nervous system and cause inflammation to the brain, spinal cord and optic nerves. MS is also a non contagious and unpredictable disease. MS is also the most common chronic disease (when it comes to the CNS (Central Nervous System)) with young Australians. Throughout all the states of Australia, Victoria is the State with the most people that have the condition.

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 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.

It was a raw, blustery March day and I was leading four classmates to my house to hash out the remaining details of our current English presentation. When I opened the door, however, I received a surprise. I had not anticipated my mother still being home and neither had my group members. Their faces turned slightly blank, as if they were trying to hide their confusion and surprise. The previously relaxed atmosphere had become very formal and quiet. I had seen this before.

Glial cells are the most numerous cells in the brain, outnumbering neurons nearly 3:1, although smaller and some lacking axonal and dendritic projections. Once thought to play a subpar role to neurons, glial cells are now recognized as responsible for much greater functions. There are many types of glial cells, including: oligodendrocytes, microglia, and astrocytes. Oligodendrocytes form the myelin sheath in the CNS, by wrapping themselves around the axons of neurons. Their PNS counterpart, Schwann cells, are also considered glial cells. This sheath insulates the axon and increases the speed of transmission, analogous to the coating on electrical wires. Microglia are considered to be “immune system-like”; removing viruses, fungi, and other wastes that are present. Astrocytes, however, are considered to be the most prominent. Their functions span throughout the brain, including, but not limited to: the synchronization of axonal transmission via G-protein-coupled receptors, blood flow regulation via the dilation of blood vessels, and the performance of reactive gliosis in conjunction with microglia. Both astrocytes and oligodendrocytes develop from neuroepithelial cells. Other types of glial cells include Radial glia, which direct immature neuron migration during development.
