Stroke is the third leading cause of death in America and is one of the leading causes of disability. Just like everything else in our body, our brain is fed by blood through arteries. And just as high blood pressure can damages the arteries of our heart, it can damages the arteries leading to our brain. If the arteries to our brain are only partially blocked, you can experience a transient ischemic attack- kind of like mini stroke. Its a brief, temporary disruption of blood to your brain caused by a blood clot or atherosclerosis. A stroke is a longer disruption of blood flow to our brain. Oxygen and nutrient are stooped from entering our brain, causing brain cells to die.
Excess sodium leads to high blood pressure, which can cause a stroke by weakening the blood vessels of the brain. A study commissioned by the World Health Organization showed that increased blood pressure was found to be the largest contributor to stroke, accounting for 62% of strokes. People with normal blood pressure(less than 120/80 mmHg) have about half the lifetime risk of stroke compared …show more content…
The artery carries fresh blood from heart to the brain. It also takes away carbon dioxide(CO2) and cellular waste. If an artery is blocked, the brain cell do not have enough energy and will eventually stop working. So, the brain cell will die. Haemorrhagic strokes occur when an artery inside our brain burst causing bleeding within our brain. This is known as intracerebral haemorrhage. It can also occur because of bleeding on the surface of our brain. Between the layers of membrane is a space, which is filled with fluid. If blood vessel near the surface of the brain burst, blood can leak into this space. This known as subarachnoid
