ischemic-stroke

Ischemic Stroke is a serious medical issue involving the Brain and the function of several main organs and systems.

It is one type of brain trauma or brain attack that is classified as a Stroke.

It has been divided into two main classifications with the other being Hemorrhagic Stroke.

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

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.

Waste, carbon dioxide, and other items are taken away from the brain.

Damage or ischemia to the brain can lead to loss of function and necrosis of the tissue of the brain due to cellular death.

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

More commonly seen in males than women.

These types of strokes vary in their severity with nearly 30% resulting in death.

 

Causes:

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]
