|Epilepsy is a disorder of central nervous system in which the activity of the nerve cell in the brain gets disturbed, which cause seizure during which abnormal behavior, symptoms and sensations, including loss of consciousness are experienced. In epilepsy the brain sends out abnormal signals which results in repeated, unpredictable seizures. The symptoms of seizure may vary among person to person. Some people with epilepsy simply stare blankly for a few seconds, while others repeatedly twitch their arms or legs. Epilepsy may be due to a medical condition or injury that affects the brain, or the cause may be unknown (idiopathic). Some common causes of epilepsy are stroke, Traumatic brain injury, brain tumor, abnormal blood vessels in the brain and other illness destroys or damages the brain tissue.
The diagnosis of epilepsy is generally made on the basis of description of the seizure and surrounding events. An electroencephalogram and neuroimaging are also included in the workup. Video and EEG monitoring is used in difficult cases. Treatment of epilepsy can reduce or prevent seizures in most patients with epilepsy because epilepsy cannot be cured but seizure can be controlled. This can help in improving the quality of life. If epilepsy is controlled it can also lower the risk of falling and other complications that can happen during seizure.
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.
