A stroke is actually a brain attack. This could happen to anyone at anytime. It may be caused by a blocked artery (ischemic stroke) or the leaking or bursting of a blood vessel (hemorrhagic stroke). Some people may have an incidence of only a temporary disruption of blood flow to their brain (transient ischemic attack, or TIA).
Surgery in Stroke
Due to stroke occurs when a part of the brain is damaged as it has been deprived of its blood supply. The blood carries oxygen and nutrients to the brain, so when the blood supply is cut off or limited, brain cells start to die. The stroke is also called as a cerebrovascular accident, CVA, cerebral vascular accident or brain attack.
Symptoms of stroke
Stroke symptoms occurs suddenly and some of the symptoms include
- sudden numbness or paralysis on the face
- onfused and having problems to concentrate
- vision problem
- feeling of unsteadiness or a sudden fall
The major cause of brain stroke is because of a blocked artery (ischemic stroke) or the leaking or bursting of a blood vessel (hemorrhagic stroke). Most of the people may experience only a temporary disruption of blood flow to their brain (transient ischemic attack- TIA).
" More than 85 percent of strokes are ischemic strokes. The Ischemic strokes occurs when the arteries to the brain becomes narrowed or blocked. This causes severely reduced blood flow. The most common ischemic strokes include:
When a blood clot (thrombus) is formed in one of the arteries that carries blood to your brain the resulting stroke is called thrombotic stroke. This clot may be caused by fatty deposits or plaque that gets accumulated in the arteries and causes reduced blood flow.
In case of an embolic stroke occurs, it is as a result of blood clot or other debris forms away from your brain, commonly in your heart and is swept through your bloodstream to house in narrower brain arteries. This type of blood clot is called an embolus.
It happens when a blood vessel in the brain ruptures or breaks down. As a result the blood seeps into the brain tissue, leading to damage the brain cells. The most common reason of hemorrhagic stroke could be high blood pressure and brain aneurysms. An aneurysm is a weakness or narrowing of the blood vessel wall.
Are strokes preventable?
Almost 50% of all strokes can be prevented. Many risk factors involved can be controlled before any stroke encounter.
The risk Factors which can be controlled are
- High blood pressure
- Uncontrolled diabetes
- High cholesterol levels
- Atrial fibrillation
- Alcohol , if taken more than one drink
- Overweight/ Obesity
- Any existing carotid and/or coronary artery disease
The risk Factors which cannot be controlled are
- Age above 65 years
- Gender- as per studies men have more strokes and Women encounter deadliest ones.
- Race – these are more common in African & American races
- Any Family History of Stroke
Our Experts can assess your risk for stroke and assist you to control the risk factors. Sometimes, people experience warning signs before a stroke occurs. These are called transient ischemic attacks (also called TIA or "mini-stroke"). Some people might have no symptoms at all to warn you prior to a stroke.
