STROKE A stroke is a disease that affects the arteries leading into as well as within the brain. “Strokes are the 4th leading cause of death in the United States. Approximately 800,000 people have strokes every year about one every 4 seconds.”1 A stroke may cause lasting brain damage, long term disability, or possibly even death. There are three main types of strokes, ischemic, hemorrhagic and transient ischemic attacks and each come with many warning signs. A person may have an increased chance
Introduction A Stroke also called brain attack, occurs when a clot block the blood supply going to the brain or there is a hemorrhage in it. Nerves in the brain requires a continuous supply of blood, oxygen and glucose to function properly. If there is impairment of this supply then the brain may stop functioning temporarily and if this impairment is severe enough then permanent brain damage could occur. As the brain control the body, so the patient could experience symptoms depending upon which
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. Strokes are the 5th leading cause of death in the US, with one person dying every 4 minutes as a result. For African Americans, stoke is the 3rd leading cause of death.(http://www.cdc.gov/stroke/facts.htm) It is estimated that About 795,000 people have a stroke each year;
Introduction Stroke is the fourth leading cause of death in the United States. Each year more than 795,000 Americans suffer from a stroke, which means that every forty seconds someone has stroke (Liebman, 2012). Although a stroke can occur at any age, strokes are frequently seen in the older adult demographics. An increase with age doubles the risk for a stroke each decade after 55 (Grysiewicz, 2008). The percentage of stroke survivors to almost fully recover from a stroke is only 10 percent; in
Stroke also known as cerebrovascular accident (CVA), cerebrovascular insult (CVI), or a brain attack. A brain attack is the loss of brain function by the cause of disturbance in the blood supply to the brain. This disturbance occurs due to either one of two causes which are ischemia (lack of blood flow) or a hemorrhage (high increase of blood flow directly into brain; parenchyma or into the subarachnoid space which surrounds the brain with tissue). Ischemia is a formation by a blood clot that is
Cerebral Circulation A constant flow of blood to the brain is vital to its proper functioning. Blood supplies the brain with oxygen and to perform maximally the brain requires about 25% of the body’s oxygen (Webb, 2016). Lack of oxygen for a prolonged period results in cell death causing irreversible damage to the brain. Two paired arteries, four total, supply the vital source of blood to the brain and spinal cord. Arterial Structures Blood supply to the brain is divided between the internal carotid

They are sometimes called ¡§mini-strokes.¡¨ The term transient is used to describe a condition that lasts only a short amount of time. Ischemic describes an inadequate blood flow. Therefore, TIA is a deprivation of blood to the brain for a short period
the medical term for a stroke. A stroke happens when blood supply to a part of your brain is suddenly cut off or extremely lowered. When this happens, the tissue of the brain gets deprived of food and air. The brain cells start to die within minutes. Having a stroke is an emergency and seeking treatment as soon as possible is crucial to surviving. The sooner you take action, the more you can minimize the amount of brain damage and potential complications that may arise. Strokes are treatable and preventable
Stroke Definition: A stroke is the sudden death of the cells in a specific area of the brain caused by inadequate blood flow. Another name for it is cerebral vascular accident (CVA). A stroke is also called a brain attack. Description: A stroke occurs when an artery bursts or becomes closed when a blood clot lodges in it and blood flow is interrupted to that part of the brain. Blood circulating to that area of the brain served by the artery stops at the point of rupture, and the brain tissue
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). A stroke can be generally
