Learn More About Stroke
Stroke is a medical term used to describe the rapidly developing loss of the functionality of the brain due to any kind of disturbance in the blood vessels that supply blood to the brain. People suffering from ischemia have the high possibility of being affected by stroke. Stroke, like a faint or a fit, is often referred to as an ictus, especially before any diagnosis is made.
Causes of Stroke
What causes stroke? Any blockage of the artery in the brain has been found to be most commonly responsible for a stroke. The clots, medically termed as thrombosis, deprive a part of the brain of blood. Naturally, the brain is also deprived of oxygen. This results in the death of the brain cells in that part of the brain.
There are certain risk factors that are intensely associated with stroke. There are high possibilities of a person getting a stroke attack if he is suffering from high blood pressure, high cholesterol level and diabetes. Habit of smoking is also one of the major risk factors associated with stroke.
Getting The Right Stroke Diagnosis
How can stroke be diagnosed? Diagnosis of stroke is made on the basis of the symptoms that the patient or the affected person reveals. After the brain cells are deprived of blood and oxygen, they die, resulting in the failure of the function that they used to perform. The failure of the functionality is obvious by virtue of the physical problems that one suffers. Let us discuss the stroke symptoms in details.
If a person suffers a stroke, the initial sensation that he would start feeling is weakness in different parts of the body, especially in the face, arm and the leg. The extent of the weakness may increase to the point of a sensation of numbness. A more obvious stroke symptom is that the weakness or the numbness would be felt in either side of the body.
It becomes completely impossible for the person who has suffered stroke, to do anything that requires the least physical labor. While talking the affected person may feel some trouble. He may also have trouble in seeing. The vision may become hazy. The weakness or the numbness in the face muscles may lead to drooling.
Are you interested to know what the treatments of stroke are? Use of the Tissue Plasminogen Activator or the TPA has been found to be the commonest treatment for stroke. It serves as a clot-buster drug. It is used so that it can dissolve the clot in the blood vessels and thereby, resume the blood circulation in the brain cells, almost dying for lack of blood and oxygen supply. In normal cases TPA is injected into a vein in the arm of the person. Drugs like Heparin and aspirin are also used for treating a stroke.
