What Is A Stroke, What Causes It And First Aid? Essay

As mentioned above, strokes are pathophysiological changes. Ischemia which accounts for 87% of all strokes is a decrease or absent circulating blood which deprives neurons of necessary substrates. As there is no storage of glucose in the brain it leaves no opportunity for the chief ingredient for energy substrate and is incapable of anaerobic metabolism (Shah, MD, n.d.). Ischemia is a medical condition diagnosed when tissues do not have a sufficient oxygen supply, therefor resulting in a decrease in ATP energy, leading to necrosis of tissue. Decreased oxygen supply to tissue (ischemia) is caused by a blockage in an artery mainly from an embolism. An embolism is the breakage of an atherosclerosis formed in any coronary arteries. This floats freely in the blood stream, which eventually may plug a major artery in the brain (stroke), heart (MI) or lungs (lung failure). A thrombus occurs when an already

Strokes are caused by a block in the blood supply to the brain which causes a decrease in oxygen and delivery of other important supplies which facilitate proper functioning. Fifteen million cases are reported worldwide annually, although not all of these cases are mortalities, the large prevalence of strokes ranks it as the fourth leading cause of death in the United States. (Figueroa) Because of the time sensitivity associated with the lack of resources to the brain, strokes are considered a medical emergency and early recognition of symptoms can help decrease the amount of damage caused . Although strokes do not always cause death, strokes most often leave the individual with some physical and cognitive impairment.

Often times, doctors will typically call a stroke a “brain attack” because the events that transpire resemble those that occur during a heart attack (Wang and Aamodt, 2010). Blood supplies a constant source of oxygen to the brain. However, a stroke occurs when that blood supply to any given part of the brain is suddenly ceased. If the blood supply to the brain is suddenly interrupted this leads to the deprivation of oxygen and glucose to that area. The brain cells that are prevented from acquiring these substances, especially oxygen, will be quickly killed off. Strokes can be categorized into two classes: Ischemic and hemorrhagic strokes (Lindley, 2008).

Many people don’t know that stroke is one of the most common life threatening diseases in the U.S alone. It has been estimated that about 25% of people who have had a stroke will have another in the years to come. What people don’t tend to realize is how much money strokes cost the U.S a year. In 2003, strokes cost about $52 billion dollars.

The Maritime Silk Road also played an important historical role. The Han Dynasty’s ocean trade routes reached as far as South Asia. There have been records of trade between the Han Dynasty, the Persian and Roman empires. These trade accounts were all achieved using these methods or maritime routes. The imported goods from this route were mainly small ornaments. Later, these sea routes connected coastal cities. This helped make trade flow more smoothly. Some of the routes also went through the Strait of Malacca to the Indian Peninsula. China’s wealthier class prospered from the beneficiaries of the luxury products given to them during the Han Dynasty. However, the usage of the maritime Silk Road was limited for various reasons. Out of the Han Dynasty, there was the establishment of a shipping lane between Guangdong and India. This helped spread the material culture of all the countries involved in the intricate routes of the Silk Road. The usage of a maritime Silk Road encouraged the spread of trade to a more vast area. This can be seen when the routes extended to the Indian Ocean and the Arabian Sea. It touched the Arab Empire and the East African coast as well. The Maritime Silk Road had other names as well. It was also known as the Maritime Chinaware Road. It is interesting because these names reflected the goods that had been transported there.

A cerebrovascular accident more commonly known as a stroke or brain attack is the term used to describe the sudden death of brain cells in a localized area due to inadequate blood flow. In order to woke the brain needs a constant supply of oxygen and nutrients. This supply is carried to the brain

Stroke is a severe medical condition and is the number five cause of death and leading cause of serious, long-term disability in America. There are three main kinds of stroke, ischemic which is caused by blood blots, hemorrhagic which is caused by ruptured blood vessels that cause brain bleeding, and transient ischemic attack (TIA) which is a “mini-stroke” caused by a temporary blood clot. It is well-known that brain cells die after a few minutes when they are no longer able to receive nutrients and/or oxygen from the blood or even when there is sudden bleeding in and around the brain. After the brain cells die, the part of the body that they control will no longer be able to function. The signs and symptoms depends on the

A stroke is a type of cardiovascular disease that affects the cerebral arteries, those blood vessels that carry blood to the brain. A stroke occurs when one of those blood vessels in the brain is obstructed or ruptures flooding the brain with blood. Depriving blood and oxygen to the brain results in those immediate cells death, causing the brain not to function properly. Once parts of the brain stop functioning, it can directly affect the areas of the body controlled (1).

Our brain is most complex organ system in our body. This three pound of tissue creates the main nerve center of the body. It controls our all body function, body movement, thought, and our behavior. Many of people do not know about the how a brain works? The left part of the brain controls our right side of the body and right side of brain part controls our left side of the body part. Our brain uses 20% of the total oxygen and blood in the body so it is required oxygen and nutrition from the blood for work properly. The lake of oxygen in the brain for 5 to 10-minute results in permanent brain damage or occurs a stroke. A stroke occurs when the blood supply to part of our brain is interrupted or severely reduced. A stroke is one of the diseases

Cerebral vascular accident or a stroke is the destruction of brain substance, resulting from thrombosis, intracranial hemorrhage, or embolism, which causes vascular insufficiency. In addition, it is an area of the brain denied blood and oxygen that is required and damage is done to a part of the cells. The effect of the patient depends upon where the damage occurs and the severity of the stroke.
