Overview

There are two types of stroke, ischemic and hemorrhagic. Hemorrhagic strokes are less common, only 10-15% of all strokes are hemorrhagic, but they are responsible for about 40 percent of all stroke deaths.[1]

Based on location of the hemorrhage, hemorrhagic stroke may be classified into intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH)
