A Short Note On The Loss Of Myelin 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.

Nearly 400,000 individuals in the United States are diagnosed with multiple sclerosis (MS). Multiple sclerosis is defined as “a potentially disabling disease of the brain and spinal cord”. (Multiple) Multiple sclerosis is classified as an autoimmune disorder in which the immune system attacks an element of itself, specifically the protective sheath (myelin) that covers nerve fibers and causes problems with communication between the elements of the central nervous system and the rest of the body. Multiple sclerosis can cause nerves to deteriorate over time or permanently damaging the nerves, which causes permanent damage to the body as nerves are unable

MS is characterized by the destruction of myelin, inflammation in the CNS and the formation of lesions in the CNS.

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 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, 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, 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).

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 (MS) is autoimmune, inflammatory disease involving the central nervous system (CNS). This disease is a result of the immune system attacking myelin proteins. Usually affecting younger people between the ages of 20 and 50 years, multiple sclerosis slowly destroys the myelin sheath that are located in the CNS causing them to eventually create scleroses, or hardened lesions. Symptoms of multiple sclerosis can be different, but visual, sensory, and motor signs are usually affected with this disease. Some early symptoms care problems like blurred or double vision, numbness, loss of balance, and weakness in arms or legs, as well as fatigue, muscle spasms, speech problems. Approximately 400,000 people in the United States and 2.5 million people worldwide are affected by multiple sclerosis (Hersh and Fox, 2014). Educating ones self about multiple sclerosis is important because it has many unanswered questions. There are many theories and treatments that may seem like they work, but there is no cure or definite reason why MS happens. Multiple sclerosis is also a disease that affects many people and is very hard to treat.

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). In the United States alone, approximately 200 new cases of MS are

Brain signals can often not reach their destination because of the damage to the nerves. What causes the damage to the myelin? Basically, T-cells which are part of white blood cells. Normally, white blood cells attack foreign substances such as viruses and bacteria or other foreign tissues but in people with MS these cells get confused and attack myelin which is why MS is considered an autoimmune deficiency. MS is often disabling meaning that a wheelchair is needed. However, people with this disease suffer from a wide variety of problems, from trouble walking and maintaining balance, muscle weakness, spasms, pain, fatigue, sensation of numbness, and vision problems to name a few. These symptoms are often in recurring periods of time with worsening symptoms, people who suffer from MS have moments where the symptoms are hardly noticeable, and moments when the symptoms are very severe (NMSS).

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 (MS) is a potentially disabling disease of the brain and spinal cord, particularly the central nervous system (CNS). In MS the immune system attacks the myelin, which is the protective sheath that covers the nerve fibers and causes communication between your brain and the rest of your body. Eventually, the disease can cause the nerves to deteriorate or even lead to permanent damage. They deteriorate in variable degrees and produce significant disability within 20-25 years in more than 30% of patients, (Luzzio, 2016). The majority of people diagnosed with MS are adults between the ages of 20 and 45; twice as many women are affected compared to men. However, MS can present itself in childhood or late middle age, but is uncommon. According to Goldenberg (2012), there is no known cause for this debilitating disease, but it appears to involve a combination of genetic susceptibility and a nongenetic trigger, such as a virus, metabolism, or environmental factors
