This picture shows a hemorrhagic stroke using an MRI image. The circle insert outlines what composes a hemorrhagic stroke. A blood vessel in the brain breaks open and blood escapes into the brain under pressure, compressing other blood vessels and brain cells causing damage and death. This bleeding into the brain is difficult to stop and is more likely to be fatal. There are two types of hemorrhagic strokes: intracerebral and subarachnoid.
“Intracerebral” means “within the brain,” and it refers to a stroke caused by a diseased blood vessel bursting within the brain. Intracerebral strokes are usually caused by high blood pressure.
A subarachnoid hemorrhage refers to bleeding immediately surrounding the brain in the area of the head called the subarachnoid space. The main symptom of a subarachnoid stroke is a sudden, severe headache, possibly following a popping or snapping feeling. Many factors can cause a subarachnoid stroke, including head injury, blood thinners, bleeding disorders and bleeding from a tangle of blood vessels known as an arteriovenous malformation.
