Types of strokes
A stroke is a
very serious medical condition. You will find that you will lose
control over some of your brain function and parts of your body will be affected, typically your arms. It happens
because your blood supply is being disrupted and not getting properly to the brain cells,
neuro system. There are many different types of strokes and they are all very
serious. You will need to learn what your risks of strokes are and if you are
someone who is genetically linked to having a stroke. Those who live in a
family that is prone to having a stroke should not increase their risk by
smoking or drinking too much. Patients who do survive a stroke will usually end up
severely handicapped.
Strokes are classified in two major categories, which consist of ischemic
and hemorrhagic. An ischemia stroke is caused because of thrombosis,
embolism, or hypoperfusion. A Hemorrhage is caused by high blood pressure in
the brain. Most of the time an ischemia is the type of stroke that will affect
you.
Ischemic
stroke
is the cause of about 80% of strokes. It is caused by the brain
getting partially
blocked or completely blocked and deprived of the proper blood supply.
Taking drugs such as cocaine, you will double your risk of ischemic
strokes.
A thrombotic
stroke is where a thrombus process develops in an artery. It causes a
blood clot that will grow and narrow your blood flow. The blood clot will then
lead to you having a stroke.
An
embolic stroke it is caused by the blockage of artery access to a part of
the brain because of debris in the bloodstream. It is usually a blood clot, but
it can also be parts of your blood vessels or even fat substances. It can also
be caused from having cancer cells in your blood. There are many reasons why
you may have debris in the blood stream, but it mostly because of an infection
or cancer cell. That is why many people don't realize that they have cancer
until they have a stroke.
Hypoperfusion or
watershed stroke is from the reduction of blood flow to the entire body. It is
do because of heart failure from a cardiac arrest. Also, it could be because of
a lower blood oxygen content in the blood. Your blood flow may not be stopped,
but since it is greatly reduced, you will have some brain damage.
A hemorrhagic
stroke is a form of stroke that will occur when a blood vessel in the brain
bursts or bleeds. The blood will irritate the brain matter and it will cause a
chemical imbalance. If it will continue to bleed, the pressure will increase on
the brain and it will be deprived of oxygen. Subarachnoid hemorrhage is a very common
source of strokes and that is where you will bleed now and then, but it will
place you in a deep coma or cause death.
