Blood Vessels that carry blood to the brain from the heart are called Arteries and each artery supplies blood to a specific part of the brain. A stroke can occur when one of these arteries to the brain becomes blocked or bursts. As a result part of the brain does not get the blood it needs and may start to die. A transient ischemia attack (TIA occurs when the blood supply is blocked for a short time). When this happens can brain can temporarily malfunction. It is very important to recognize the signs and symptoms of a TIA which may mean an impending stroke.
There can been different types of stokes and identifying the type of stroke can lead to quicker
Ischemic stroke: Ischemic stroke is the most common type of stroke. An ischemic stroke happens when
an artery in the brain is blocked. There are two types of ischemic stroke.
Embolic stroke: A blood clot or plaque fragment forms, usually in the heart or the large arteries leading
to the brain, and then moves through the arteries to the brain. In the brain, the clot blocks a blood
vessel and leads to a stroke.
Thrombotic stroke: A thrombotic stroke is a blood clot that forms inside an artery that supplies blood to
the brain. The clot interrupts blood flow and causes a stroke.
Hemorrhagic stroke: happens when a blood vessel in the brain bursts and spills blood into or around the
brain. High blood pressure and aneurysms can make blood vessel weak enough to burst. There are
different types of hemorrhagic stroke, including intracerebral hemorrhage and subarachnoid
Intracerebral hemorrhage: is caused when a burst blood vessel bleeds into the brain tissue. The
bleeding can cause brain cells to die. High blood pressure also called hypertension is the most common
cause of this type of stroke.
Subarachnoid hemorrhage: In this type of stroke, a blood vessel bursts near the surface of the brain and
blood leaks in between the brain and skull. This type of stroke is usually caused by a burst aneurysm
Prevent a stroke
If you have high blood pressure then get it under control. For people age 18 and above high blood
pressure if a measurement of 140/90 or higher.
Find out if you have atrial fibrillation (A fib). Atrial fibrillation is an irregular heartbeat that can cause
blood to pool in parts of the heart. This blood can form clots and cause a stroke. A fib can be treated.
If you smoke, stop. Smoking doubles the risk for stroke.
If you drink alcohol, do so in moderation. Heavy drinking can increase your risk for stroke.
Lower your cholesterol (the fat-like substance in your blood). The total cholesterol should be under 200
and the LDL (bad) cholesterol should be between 50 and 70 or about half of the LDL cholesterol before a
If you are a Diabetic then follow your doctor’s advice carefully to get the blood sugar under control.
Having diabetes puts you at an increased risk for stroke.
Exercise daily. Even a little exercise such as a brisk walk, bicycle ride, swim or year work can improve
your health and reduce the risk for stork.
Cut down on sodium and fat. Less salt and fat can lower the blood pressure and reduce the risk for
***Note the time when any symptoms first appear. Medical options exist that may reduce the effects of
stroke if administered after the onset of symptoms.
