Secondly called hemorrhagic stroke that is caused by a blood vessel that breaks and bleeds inside the brain. 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.
