Understanding Stroke

There are two primary categories of stroke. Ischemic stroke and hemorrhagic stroke.

Ischemic Stroke

This is the most common type of stroke. It is caused by an interruption of blood flow to the brain. This may occur when a blood clot forms and closes an artery, or when a clot (embolus) has travelled through the circulation into a brain artery. The symptoms of ischemic stroke will depend on what area of the brain is involved.

Hemorrhagic Stroke – Intracerebral Hemorrhage

Hemorrhagic stroke is less common than ischemic stroke, but it is more dangerous in terms of survival. An intracerebral hemorrhage results from breakage (rupture) of a blood vessel in the brain, allowing blood to spread into the brain. The most common associated condition leading to intracerebral hemorrhage is high blood pressure.
