How does a stroke occur. 63 It can be caused by bacteria aspirated form the oropharynx or by the chemical effects of the gastric acid on the bronchial mucosa. Once this supply is tampered with the brain cells in the part affected starts dying within minutes and so do the body functions controlled by.

A myocardial infarction MI commonly known as a heart attack occurs when a portion of the heart is deprived of oxygen due to blockage of a coronary artery. The brain cells deprived of the oxygen and glucose needed to. Stroke requires immediate medical attention.

Post-stroke pneumonia is due to a combination of dysphagia aspiration 8 and stroke-induced immunosuppression. A stroke occurs when a blockage or bleed of the blood vessels either interrupts or reduces the supply of blood to the brain. A stroke is a severe medical issue and getting ahead of the problem can make all the difference.

Without oxygen and important nutrients the affected brain cells are either damaged or die within a few minutes.

Eighty percent of strokes are ischemic caused by the narrowing of the large or small arteries of the brain or by clots that block blood flow to the brain. They happen when a blood clot blocks the flow of blood and oxygen to the brain. Lack of oxygen kills the brain cells that this particular blood vessel serves and the part of the body that these brain cells control stops working.

A stroke sometimes called a brain attack occurs when blood flow to an area in the brain is cut off.
