Causes
A stroke happens when blood flow to part of the brain is interrupted due to a blood vessel in the liver is blocked or broken. If blood flow is stopped for more than a few seconds, the brain can not get blood and oxygen. Brain cells can die, causing permanent damage. There are two main types of stroke: ischemic stroke and hemorrhagic stroke.
Ischemic stroke occurs when a blood vessel supplying blood to the brain is blocked by a blood clot. This can happen in two ways:
* You can form a clot in an artery that is already very close, which is called a thrombus. If you block the artery completely, is called a thrombotic stroke.
* A clot can break off from somewhere in the body and travel to the brain to block a smaller artery. This is called an embolism, causing an embolic stroke. Read the rest of this entry »
