What is a stroke?

There are many people that have to deal with the problems of having a stroke at some point in their life. This is not something that is going to be easy to get through but it is possible.  A stroke is a problem that is going to affect blood vessels that supply blood to the brain. 

A stroke will usually happen when a blood vessel that brings oxygen and nutrients to the brain bursts or is clogged by a blood clot or some other mass such as fatty deposits or furring.  This is thought of as a rupture or a blockage and part of the brain does not get the blood and oxygen that it needs. This is a very dangerous and scary time for anyone to go through. This means not only the people that have the stroke but also for the people that are around when this ordeal is going on. 

When there is not enough oxygen the nerve cells in the affected area of the brain, which causes them to not work, that the part of the body that they control does work correctly.  This is a very hard problem to deal with, especially after a severe stroke has taken place.  There can be permanent damage to the brain cells, which are not replaced. The brain cells do not regenerte like other body cells.

There are two types of stroke.  One is the Ischemic stroke that is cause by a blockage of the blood vessels.  The other is called a hemorrhagic stroke caused by bleeding. Bleeding strokes have a much higher death rate that caused by clots.

The Ischemic stroke is the most common form.  It is going to occur when a blood clot forms and blocks the flow in an artery bringing blood to part of the brain.  Blood clots usually form in the arteries of the brain. This is called a cerebral thrombosis stroke.  This is going to usually happen first thing in the morning or at night. 

A hemorrhagic stroke is a hemorrhage that occurs when a blood vessel on the brains surface ruptures and bleeds into the space between the brain and the skull.  A cerebral hemorrhage will happen when a defective artery in the brain breaks and this will fill the surrounding tissue with blood.

When a blood vessel in the brain bursts, pressure from the blood will compress part of the brain. If the person does happen to live through this ordeal, the pressure will eventually go away.  Then the brain may regain some of its former function again.  It is important to seek medical treatment as soon as possible when a stroke occurs. This way a person can get the help and the treatment that they need to recover and live through this devastating ordeal that can cause great damage to a person's physical and mental well being.
