Multiple Sclerosis

Multiple sclerosis is the disease that affects the central nervous system. The persons own immune system is responsible for this disease. In this disease the myelin sheath that surround the nerve cells of the central nervous system get damaged. Due to damage to the myelin sheath there is interruption in the nerve cells communication that directly affects the body of the person as the nerve signals are interrupted. Due to this the nerve cells get damaged which is irreparable. The person suffers from weakness, thinking problem, blurred vision and the person may suffer from some attacks also. As the person nerve cells are damaged so there is no cure for this disease. However treatment for this system only includes treatment of symptoms and making the person live longer. The cause of multiple sclerosis is still unknown. It is thought to occur because of environmental factors, some infectious agents or genetic factors. The diagnosis based on signs and symptoms do not confirm this disease because the symptoms may be similar to the symptoms of other diseases also. Only from the medical history the doctor can confirm the diseases by some diagnostic methods like neuroimaging and cerebrospinal fluid analysis. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
