Multiple Sclerosis is an autoimmune disorder which is characterized by multiple areas of scarring to nerve fibers of the CNS. It often affects people between 20 to 40 years. Currently there are about 1.1 million people suffering from multiple sclerosis. Like most of the autoimmune diseases females are more affected than males in this disease. Multiple Sclerosis effects the central nervous system (brain and spinal cord). The disease commences with a discrete attack known as CIS (clinically isolated syndrome), which may attack any area of the CNS but mostly attacks either the brain stem, optic nerve or spinal cord.
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

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, 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 (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.
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.
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, 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 an autoimmune disease, in which the body's immune system attacks its own tissues. The disease destroys the myelin, which is the insulation that protects the nerve fibers in the spinal cord, and brain (Niino, 2008). When the myelin is damaged, the message that is traveling along that nerve may be slowed or blocked. Symptoms vary by patient, but often include: numbness or weakness in limbs, partial or complete loss of vision, lack of coordination or unsteady gait, slurred speech, fatigue, dizziness, and problems with bowel and bladder functions.
“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 as it is more commonly referred, is an immune mediated disease that involves the body's own defense mechanism, specialized immune cells, that ultimately attacks the central nervous system. Specifically, the myelin protein that coats axons and forms an electrically insulating layer for quicker processing of the nervous system, is attacked by cytotoxic cells that have crossed into the CNS. In a healthy patient, the blood brain barrier cannot be crossed by cytotoxic cells and it is speculated that an environmental component or outside source mediates this crossing. When the myelin is attacked, it forms scars in the CNS, as multiple sclerosis literally translates to “many scars,” which is the direct result of the disease. The scars disrupt the normal nerve impulses that travel through the central nervous system, and can cause a variety of symptoms including loss of cognition, fatigue, or numbness in the body (Evidence).
Multiple Sclerosis is a disease that attacks the myelin coating over the nerve receptors in your brain and spinal cord. Myelin is a fatty material that coats and protects the nerves in your brain. These nerves send signals to the rest of your body enabling
Multiple Sclerosis is a long-lasting disease that can affect your brain, spinal cord, and the nerves in your eyes. It can cause problems with your vision, balance, muscle control, and other bodily functions. There is no cause for Multiple Sclerosis but there are many symptoms that can lead you to think that you do have this special disease. Starting with vison loss, pain, fatigue, and impaired coordination. Some people can be symptom free, meanwhile some have those chronic symptoms that never go away. When you begin to have MS, it starts in your immune system, then attacks your central nervous system. There are more than 350,000 people in the United States have this progressive disease. Including Northern Europe, Southern Australia,
If you know anyone with Multiple Sclerosis or MS, you would know how terrible the disease is. Multiple Sclerosis is an inflammatory disease in which your immune system attacks the nerve cell covers in the brain and spine are damaged. The nerves in the body eventually deteriorate and it is fatal. According to the National Multiple Sclerosis Society, the cause of Multiple sclerosis is still unknown. There is not a cure at the moment for Multiple Sclerosis, but there are treatments that can speed recovery when attacked by the disease (Mayo Clinic). Scientists are under the impressions that there are a few factors that may come into play. They say that when they discover the exact cause of Multiple Sclerosis it will be easier to find a way to treat the disease or maybe even stop it from happening at all.

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