Introduction
Cerebral vascular accident (CVA) better known as stroke is medical emergency responsible for an enormous numbers of death in the united states. Stroke it is listed as the number four leading cause of death in the United States. There are three different types of stroke ischemic stroke, hemorrhagic stroke and transient ischemic attack. Compare to any other disease cerebral vascular accident or stroke is one of the main reason for disability among adults in the united states.
History
It all began when the father of medicine Hippocrates first discover stroke many centuries ago. Back then stroke was known as apoplexy a Greek term meaning “Struck Down by Violent” because at the time they did not have an explanation for it.

Cerebral vascular accident (CVA) or stroke is an injury to the brain that occurs when arteries responsible to supply blood to the brain become clotted or blocked preventing blood flow causing it to leak blood onto or into the brain. The damage of a stroke in the brain can affect the entire body, resulting from mild to severe disabilities, which include paralysis preventing anyone from walking, understanding , numbness of the face , arms, legs and emotional problems.

Ischemic Stroke tends to occur when the artery responsible to supply oxygen rich blood to the brain becomes clotted or blocked. Another type of stroke is Hemorrhagic Stroke it occurs when an artery in the brain is rupture causing it to leak. The leaks puts too much pressure on the brains cells ,which damages them. Hemorrhagic stroke is also divided into two categories : Intracerebral hemorrhage, which is the most common type of hemorrhagic stroke , it occur when an artery in the brain bursts , flooding the surrounding tissue with blood. And subarachnoid hemorrhage, which is a lest common type of hemorrhagic stroke, it occurs when there is bleeding in the area between brain and thin tissues that covers it. Last but not least is the Transient Ischemic Attack also known as TIA or sometimes call “mini stroke” . This specific stroke is different from others major types of stroke because it occurs when the blood flow is blocked for only a short period of time (no more than five minutes). Statistics
Each year according to National Institute of Neurological Disorders and Stroke more than 700,000 Americans suffer a stroke and about 160,000 die from stroke-related causes. In early 2011 at the American Stroke Association it was reported that the incidence of stroke has rose 51% among men and 17% among women aged fifteen though thirty-four years between 1994-1995 and 2006-2007.
Risk
There are three types of strokes that cause changes to the brain: Hemorrhagic stroke,Intracerebral hemorrhage and Transient ischemic attack (TIA). Ischemic stroke is the most common form of stroke, accounting for around 87% of strokes.
Hemorrhagic stroke is, the less common types of CVA, nearly 13% is all stroke cases and is a result from bleeding into the brain tissue itself (Intracerebral and intraparenchymal hemorrhage) or into subarachnoid space or the ventricles (subarachnoid hemorrhage or intraventricular hemorrhage). This type of stroke is further subdivided into:
The health issue that this artifact discusses is the significance of knowing and recognizing the warning signs of a stroke. The American Heart Association has made it their mission to provide unlimited health information and research in the hopes of eliminating cardiovascular diseases as well as helping society in maintaining a healthy lifestyle. “Stroke is the number 5 cause of death and a leading cause of
Stroke previously known as Cerebrovascular accident is well-defined as ‘an abrupt cessation of cerebral circulation in one or more of the blood vessels distributing the brain. Due to the interruption or diminish of oxygen supply causes serious damage or necrosis in the brain tissues (Jauch, Kissella & Stettler, 2005). There is a presence of one or more symptoms such as weakness or numbness or paralysis of the face, arm or leg, difficulty speaking or swallowing, dizziness, loss of balance, loss of vision, sudden blurring or decreased vision in one or both eyes and headache. Stoke is categorised into two types, Ischaemic and haemorrhagic
Stroke was first recognized over 2,400 years ago by Hippocrates, known as the “Father of Medicine.” At the time, it was called apoplexy meaning “struck down by violence” in Greek because of the sudden paralysis and the change of well-being of the victim. Due to the lack of knowledge of the brain, it wasn’t until the mid-1600s that it was discovered by Jacob Wepfer that the cause of apoplexy is due to the bleeding
The cerebrovascular accident occurs due to a sudden death of some brain cells by a lack of oxygen when the blood flow to the brain is impaired by blockage or rupture of an artery to the brain. When it occurs, it can leave some sort of body function deficit. The pathologic of cerebrovascular accident can be categorized into two types the hemorrhage stroke and the ischemic stroke. The ischemic occurs with a blockage of a blood clot that causes a lack of blood supply in the brain tissues. In the hemorrhage stroke, on the other hand, it occurs due to a rupture of a blood vessel (artery aneurysm) which result of bleeding in the brain area. The ischemic stroke is the most common type of stroke Thompson and Lindholm (2014), stated that about 80 out of 100 strokes are ischemic strokes. The most common cause of the hemorrhagic stroke is due to a
Cerebrovascular disease is “any abnormality of the brain caused by a pathologic process in the blood vessels.” (McCance, 2015) Aneurysms and strokes or cerebrovascular accidents encompass this category. There are three categories of strokes: ischemic (thrombotic or embolic), global hypoperfusion, and intracerebral hemorrhage. Thrombotic strokes are caused by arterial occlusions from blood clots formed in the arteries supplying the brain or in the intracranial vessels (McCance, 2015). The development of blood clots or thrombi in the venous channels of the brain is called cerebral thrombosis. Cerebral thrombosis is mostly ascribed to atherosclerosis and inflammatory disease processes that damage arterial walls. Inadequate cerebral perfusion creates damage in the arterial walls where platelets and fibrin attach to forming a thrombus. “Portions of the clot detach and travel up the vessel to distant sites where occlusion occurs, producing a stroke syndrome.” (McCance, 2015) An embolic stroke occurs when a fragment that breaks from a thrombus outside of the brain occludes a cranial artery, usually the middle cerebral artery.
There are 2 types of hemorrhagic strokes: an intracerebral hemorrhage happens when a blood vessel in the brain bursts and spills into the surrounding brain tissue, damaging brain cells. A subarachnoid hemorrhage happens when an artery
A cerebral vascular incident can happen to anyone at anytime. Some people know it be called a stroke, CVA, or brain attack. The majority of patients who have had a stoke will have another one within one year. Stoke tend to occur more often in the southern United States also known as the “stroke belt”. This may be related to the larger number of elderly, tobacco use, and obesity. A cerebral vascular accident ranks high in the major leading causes of death in the United States, and it happens nearly every four minutes. There are three different types of stroke ischemic, hemorrhagic, and transient ischemic attacks. The larger number of cerebral vascular accidents is known to be ischemic. The artery that supplies the brain with blood
A stroke can be generally be defined in two types of categories. The first and most common type of stroke is called ischemic stroke. This occurs when a blood clot (cerebral thrombosis) blocks a blood vessel in the brain. Blood flow beyond the blood clot is then
A stroke caused by a blocked artery by a blood clot or bursting of a blood vessel because of uncontrolled high blood pressure. There are main three types of the stroke. An ischemic stroke occurs when a blood clot blocks one of the arteries which supply blood to brain. A clot may be caused by fatty deposits (plaque) that build up in arteries and cause reduced blood flow (atherosclerosis) or other artery conditions. (mayo clinic). About 89%, strokes are ischemic strokes. Ischemic stroke includes thrombotic stroke. A thrombotic stroke occurs when a thrombus stuck in one of the arteries that supply blood to the brain. A clot build-up of fatty deposits in arteries. Another type of stroke is called the hemorrhagic stroke. This stroke occurs when a blood vessel leaks or ruptures in the brain. A bold vessel leaks or ruptures from many conditions like uncontrolled high blood pressure or overtreatment with anticoagulants and the weak spot in blood vessel walls. (mayo). Some people experience a mini-stroke it is known as a transient ischemic attack (TIA). A temporary decrease or clot stuck in a vessel in our brain causes TIA. It happens less than five minutes. This stroke does not have any symptom, because the blockage is
Cerebral Vascular Disease (CVA) also known as a Stroke, occurs when there is a poor or inadequate flow of blood to part or all of the brain (Ischemia). Or bleeding in the brain (hemorrhage) that leads to brain cell damage or death. Resulting in loss or impairment of functions such as movement, emotions or sensations; depending on the affected area. The amount or severity of the loss depends on the area affected and the extent of the damage to the brain and its cells. According to Medical-Surgical Nursing ninth edition, stroke is the fourth leading cause of death in the United States. The leading cause of long-term disability and twenty-six percent of the stroke victims require a minimum of three months of long-term care. Stroke is a devastating and preventable disease, with a huge emotional and financial impact on the victim and their families. One example is Roberto Severino Campos, who resides with his family in San Paulo, Brazil. According to Roberto 's story on the World Health Organization website, he refused to be concerned about the warning signs predisposing him to a stroke. Roberto was not concerned with his hypertension, smoking and drinking; which are all preventable factors. Now after three strokes, he can no longer speak and has left side with bilateral leg paralysis. Roberto can no longer work and is totally dependent on his family for survival. Stroke has been the foremost helth care concern and prevalent killer for the Brazilian population.( Bode, Chris de,
Stroke (also known as cerebrovascular accident or CVA) is a lifestyle disease. It is one of the most common diseases and one in sixth of people will have a stroke in their life. Around fifteen million people around the world have a stroke (per year). Out of those fifteen million around 5 million recover,5 million die and 5 million become disabled.
A Stroke is a condition that could happen to anyone, making it the fourth leading cause of death in the United States of America. The National Institute of Neurological Disorders and Stroke estimated that “8 out of 10 strokes can be prevented”
A stroke occurs when the blood supply to the brain is cut off or constricted. This deprives the brain of vital nutrients and oxygen. Death of brain cells can occur within minutes. There are three main different types of stroke. The most common type of stroke is a ischemic stroke. This occurs when the arteries to the brain become blocked or narrowed. This is often caused by a clot made of fatty deposits. Another kind of stroke is a hemorrhagic stroke. This type of stroke occurs when a blood vessel in the brain leaks or ruptures. The third type of stroke is a Transient ischemic stroke also known as a mini stroke. This occurs when there are small debris that block the blood vessles that supply the brain. There are temporary stroke symptoms which
