Ischemic Stroke is a type of stroke that results when oxygen is lacking (Ischemia) in a portion of the Brain which is most often caused by a stoppage of blood flow.

The resulting injury in the brain can have significant problems with the function of several main organs and systems of the body.

Stroke classification overall means that there is injury in the brain. Ischemic Stroke is one category.  The other classifications is called Hemorrhagic Stroke.  Hemorrhagic stroke often means that a brain bleed has occurred.

Ischemic Stroke

A blockage in the blood vessels of the brain leads to the lack of oxygen. In other words, it is similar to a heart attack but of the brain. Blood allows oxygen and nutrients to be brought to the tissue of the brain. This blockage could be from air, a clot, or something else.

In normal situations, waste, carbon dioxide, and other items are taken away from the brain. When a stroke occurs, damage or ischemia to the brain can lead to loss of function and necrosis of the tissue of the brain due to cellular death. That means that those waste products cannot be easily removed for certain areas of the brain. Brain tissue death can ensue.

Ischemic Stroke accounts for more then 80% of all stokes and average age is above 60 years of age.

It is more commonly seen in males than women. These types of strokes vary in their severity with nearly 30% resulting in death.


1.)  Thrombotic – [blood clot that has formed locally]

2.)  Embolitic –  [blood clot or foreign matter from somewhere else in body]

3.)  Systemic Hypoperfusion –  [Decreased blood flow due to shock or other factor]

4.)  Cryptogenic –  [Unknown origin]

Risk Factors:

***Symptoms may develop quickly, within a few minutes, or worsen over a few hours

TIA –  Transient Ischemic Attack – may precede or give warnings to a major ischemic stroke


–  Emergency Room visit
