Multiple Sclerosis Multiple sclerosis is a degenerative disease of the central nervous system. In multiple sclerosis, the immune system of the body attacks the myelin sheath. Myelin is a fatty substance rich in proteins that surrounds, insulates, and protects the nerve as well as helps to speed up nerve transmissions. Neurons are the basic working part of the brain that transmit messages to other nerves in the body. Every neuron in the central nervous system has a cell body and an axon. An axon is the extension of the cell body that carries messages and it is here that myelin plays its role. Myelin is wrapped around the axon for protection and allows for electrical impulses to be transmitted quickly and efficiently. When the body attacks its own tissues and causes a breakdown in the myelin layer, the nerve impulses that are travelling to and from the brain are altered. Impulses are slowed down, distorted from their original manner, or sometimes interrupted entirely. Over time, multiple sclerosis can cause deterioration of the nerve itself. Multiple sclerosis, often referred to as MS, is called “multiple” for the many areas of the brain that are affected and “sclerosis” for the scarring of tissue and lesions that form on the brain and spinal cord.
The symptoms of MS can vary significantly from one person to another depending on what area of the central nervous system the lesions are present. Some of the most common symptoms are blurring vision, loss of vision, fatigue,
Myelin covers nerve fibers and can cause communication problems between the brain and the rest of your body when diagnosed. MS can cause your nerves to deteriorate or become permanently damaged and is a potentially disabling disease of the brain and spinal cord (the central nervous system). if you pick up a hot pan by accident, your body is going to naturally want to drop the pan. Someone without MS would drop the pan right away. For someone with MS, your sensory neurons cannot send the signal to your brain and back to the motor neurons so you can drop the pan. MS can cause your nerves to deteriorate or become permanently damaged. MS is a potentially disabling disease of the brain and spinal cord (the central nervous
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).
Most MS patients start with the development of transient sensory loss due to the demyelination of the dorsal column, which may progress to motor symptoms including limb muscles weakness or muscle spasticity due the demyelinationg of the upper motor fibres such as corticospinal and corticobulbar tracts.

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.

Other symptoms include spasms. One spasm is known as the “drop foot.” A person could be casually walking and suddenly, his or her foot can basically shut down and drop. Spasms usually result in muscle stiffness and uncontrollable jerk-movements, according to Healthline Editorial Team, George Krucik, MD, MBA , Early Signs of Multiple Sclerosis, January 25, 2013. Another common symptom would be fatigue. This fatigue remains constant due to the deterioration of the central nervous system. With fatigue also comes muscle weakness, loss of motion and touch, which mostly occurs in the hands and legs. A few other symptoms include short-term memory loss, slurred speech,
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 (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 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.
Multiple Sclerosis; also known as MS, is a chronic and degenerative disease that affects the central nervous system. It is a disease in which the body is attacking its own myelin as if it was a foreign substance. This disease is currently affecting about 2.3 million people in the world (Tran, 2014).
Multiple Sclerosis is a debilitating neurological disorder that is an abnormal response of the body’s immune system which is directed against the central nervous system. The immune system attacks glial cells called “myelin”. Damaged myelin is turned into scar tissue. This scar tissue is called “sclerosis”, which gives this disease the name “Multiple
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
Multiple sclerosis (MS) is a chronic degenerative neurological disease with a prevelance about 74 in 100 000 people in Belgium (Rosati), MS can cause many symptoms but also difficulties in vision, mood, cognition, speech, upper and lower limb function, bladder and bowel function, sexual function and fatigue but depression can also be present.( burke) Research has shown that people with MS are less active than healthy persons (Sanderhoff). As a result, they will have no effect of physical activity and this will worsen the general health. The body experience will reduce and the loose their identity because the disease will take the lead in their life. Research has shown that when patients with MS exercise on regular basis, they experience fewer
