About 87% of the majority stroke are ischemic stroke [5]. The main cause of the ischemic stroke is the narrowing in the arteries [1]. There are two types of ischemic stroke, the first one is an embolic stroke, which is created outside the brain and transfer from the body to the brain by the bloodstream. The second one is the thrombotic stroke that performed inside one of the arteries directly supplying the brain [5].
