Deyelinating Disease: Multiple Sclerosis

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).

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 (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 (MS) is a disease in which your immune system attacks the protective sheath (myelin) that covers your nerves” (Mayo Clinic). The immune system is a defensive system that protects your body from diseases and illnesses such as parasites and bacteria (Science Museum). Not only does your immune system defend the human body but also the immune system can work against the body, which is known as autoimmune disease. Since the immune system is working against your body to attack the myelin, this creates an opportunity for multiple sclerosis to invade the nerves in the central nervous system (CNS). The myelin within the body acts like insulation to protect and coat the nervous system (National Multiple Sclerosis Society). Once the myelin is eroded, the nerves become exposed which then causes signals to and from the brain to become distorted or irrupted causing a wide range of symptoms to occur (National Multiple Sclerosis Society). The effect of the myelin eroding is an irreversible process (Mayo Clinic). “The damaged myelin forms scar tissue (sclerosis), which

Multiple sclerosis, or MS, is an autoimmune disease in which the body’s immune system targets the central nervous system (National Multiple Sclerosis Society, 2016). The central nervous system is mainly made up by the brain, nerves, spinal cord, and optic nerves (National Multiple Sclerosis Society, 2016). The main target in MS is myelin, the substance that protects the nerve fibers within the central nervous system (National Multiple Sclerosis Society, 2016).

Multiple sclerosis is an unpredictable, crippling neurological disease of the central nervous system, which affects the flow of information within the brain, and between the brain and body. The name is this disease refers to multiple areas of scarring throughout the brain and spinal cord. This scarring is a result of what happens when the body attacks itself. A substance called Myelin surrounds the nerves to help protect them (Healthline.com, 2015). Multiple Sclerosis is thought to occur in a genetically susceptible individual (although there is no evidence to show that the disease is directly inherited) influenced one or more environmental factors. MS is thought to be an autoimmune disease, however others disagree as the target of the immune

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

MS is an autoimmune disease, meaning the immune system attacks the bodys own myelin sheath protection. The damaged myelin and axon fibers is caused by overactivated T cells.

The main cause of MS is yet to be known, researchers have suggested that MS is a demyelinating disease. Here myelin gets degenerated. Myelin is a material which is composed of fats and provides insulation for the nerves. This insulation of fat contributes in transmission of impulses with very high speed, allowing people to move almost without thinking. Therefore, when this myelin sheath is not present it cause a short circuiting like case and the person cannot move rapidly, smoothly and coordinate movements. According to researchers the immune system mistakes the myelin as a foreign body and attacks to destroy this myelin. It is not known yet what triggers the immune system but it is thought to be a combination of many factors. Among a few theories a virus that lies dormant in the body plays a major role in the causing of this disease by disturbing the immune system or indirectly contribute to the autoimmunity. Another one of the theories also says that it is not because of any specific virus but a common virus like herpes or measles which activates the

Multiple Sclerosis, also known as “MS” is a chronic condition where the immune system begins to destroy the myelin sheath that covers the nerves in the body and affects the brain and spinal cord (Mayo Clinic Staff, 2014). The myelin sheath is used for protection of the nerves in which these nerves aid to transport nerve impulses all over the body (Ruto, 2013). Once the body’s immune system attacks the myelin sheath, it begins to disintegrate which affects the conductivity of the nerve impulse and impedes the message transmission from the brain to the rest of the body (Ruto, 2013). In turn, the impulses are changed which results in problems in the muscle such as weakness, imbalance and spasms and the body could end up

Multiple Sclerosis (MS), is considered to be "a immune-mediated disease" (nationalmssociety.org). This means within the Central Nervous System (CNS), the immune system mistakenly attacks myelin – The "fatty substance that surrounds and insulates the nerve fibers" (nationalmssociety.org) – as well as nerve fibers themselves. When the myelin and nerve fibers are damaged, the myelin interferes with nerve conduction. The symptoms of MS relate to this interruption of signaling between

Multiple Sclerosis is a chronic progressive disease involving damage to the myelin sheaths of nerve cells in the brain and spinal cord. The exact cause of multiple sclerosis is unknown but we know that something triggers the immune system to attack the central nervous system (CNS). MS happens when your immune system attacks a fatty material called myelin and without this outer shell, your nerves become damaged. The resulting damage to myelin that insulates wire like nerve fibers is a disruption of signals to and from the brain. This hiatus of communication signals causes unpredictable symptoms such as numbness, tingling, mood changes, memory problems, blindness, paralysis, fatigue and pain. People who have MS experience the disease differently,

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
