Multiple Sclerosis Causes
What is Multiple Sclerosis?
Multiple Sclerosis (MS) is related to the central nervous system of human being. This system consists of the spinal cord and brain. The MS causes damage to the Myelin. Myelin stimulates the flow of impulses in nerve cells. This process is called the demyelination, which also causes permanent disability in brain. As more nerves are damaged, a patient will experience more severe affects on the central nervous system. In this condition, senses of speech, vision or memory can be affected permanently.
Causes of Multiple Sclerosis
The Central Nervous System controls muscle movements and physical actions. This system transmits signals and information to the brain from all the senses (touch, smell, vision and taste). These signals are transmitted through nerves (fibers). The signals carried by these nerves help humans in behavior, thinking, communication and to be alert.
When a disease's virus affects brain and spinal cord, the central nervous system loses its control. Multiple sclerosis is the result of this process. The root causes of multiple sclerosis have not been detected, but doctors believe that virus infection, environment and changes in genetics are the major causes for MS.
Environmental Factors
Researchers have proved that multiple sclerosis is mostly found in temperate atmosphere. Hence, the countries covered by both hemispheres contain most of the MS affected people. The lack of sunlight increases chances for MS risk. People of these areas usually do not expose to sun and fail to gain vitamin D. the less amount of Vitamin D is considered as the main element to define MS.
Different ethnic groups also experience different common symptoms of multiple sclerosis. Scandinavia and Scotland contain more MS patients compared to other European countries. Multiple Sclerosis is major concern in whites than other racial groups in U.S.
Genetic Factors
A number of MS cases have shown that the risk of Multiple Sclerosis disease is higher in the relatives than general population. The inheritance of genes through parents to children may cause multiple sclerosis. This risk is high in the first three level relatives of MS acquired people, especially children, parents and siblings. More than 30% of the MS cases come under genetic inheritance factor.
The genetic transformations make a child susceptible to MS. Researchers are using new techniques to find genetics' influence for developing Multiple Sclerosis.
Infections
Epidemiological explanation finds that multiple sclerosis risk is increasing through infections. Most parents are infected by various viruses that have the presence of oligoclonal bands in their cerebrospinal fluid and brain. This virus has association with demyelinating process, which is the man cause of multiple sclerosis. Apart from all these factors, scientists have found that children and adults are the major part of the MS affected people. Multiple Sclerosis' symptoms are mostly experienced during the teenage and adulthood. The women population is also more compared to men.
The sex hormones and testosterone can affect the immune system. However, all these factors can be controlled, and various trials can be administered to reduce their development. They can be eliminated through new clinical trials that researchers are investigating for Multiple Sclerosis’ treatment.
