The stroke causes include the formation of a blood clot in the brain
or blockage by a clot that traveled to the brain from another region
like the legs. A stroke is a medical condition that occurs when blood
supply to the brain is blocked.
It is also known as a brain attack, cerebral infarction or
cerebrovascular accident. Stroke causes include blockage by a blood
clot or interruption of blood flow due to a ruptured blood vessel.
stroke symptoms usually come
on suddenly and can include headache, muscle
weakness or numbness on one side of the body, changes in
vision or hearing, confusion, decreased alertness, loss of balance,
difficulty speaking, dizziness, clumsiness and loss of bladder control.
Strokes caused by blood clots are called ischemic strokes. Hemorrhagic
strokes are caused when a blood vessel in the brain bursts open.
Cardiovascular disease including high blood pressure and high
the risk of stroke. Other
medical conditions are
linked to a higher than average incidence as well. What
causes a stroke can include: diabetes, bleeding disorders, heart
disease, age, family history and
head injury. In addition to this in some cases medications might
contribute to an increased risk of stroke.
Since unhealthy lifestyle choices result in heart disease, stroke
prevention involves making heart healthy choices. Choose a diet that is
low in unhealthy saturated fat and alcohol. Maintain an ideal body weight and
exercise on a regular basis. Don't smoke and get regular medical
checkups. Keep track of blood pressure readings and cholesterol levels.
Follow the doctor's recommendations regarding frequency of testing. In
addition, if heart disease or diabetes is present, follow the treatment
plan closely to avoid complications. When there is a high risk for
stroke, the doctor may suggest
blood thinners or he may perform a procedure called a
endarterectomy that treats
clots in the neck arteries.
A stroke can
be diagnosed with tests and scans of the brain.
If a stroke is suspected, medical treatment should be sought
immediately. Experts recommend the appropriate treatment to begin
three hours of the first sign of a stroke for the best possible
outcome. Strokes are treated with medications that break apart clots if
the stroke is caused by a blood clot or by surgery to repair a
ruptured blood vessel. Depending upon the severity of the stroke, long
term therapy may be needed to regain control of the affected body side.
A stroke is a medical emergency that can have severe long term
The outlook for recovery depends upon what part of the
brain is affected and how soon treatment is started.
However, over half
of all stroke sufferers are able to return home and function
independently. Others may be left with permanent
disabilities as a result of the brain damage incurred.
Therefore, prevention is
of importance by eliminating the stroke causes that can be
controlled through healthy lifestyle choices
