Types Of Stroke Ischemic Stroke And Ischemic Attack

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.

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:

A stroke is a condition which is characterised as loss of brain functioning due to an interruption in the blood flow to the brain (Buzzard, 2013, pg. 5). There are two types of strokes, ischaemic and hemorrhagic strokes (Buzzard, 2013, pg. 6). Ischaemic strokes are the most common type of stroke (Gomes & Wachsman, 2013). This type of stroke occurs due to an insufficient flow of blood to the brain, which is usually caused by an artery blockage (Gomes & Wachsman, 2013). Hemorrhagic strokes are due to hypertension and may be caused by medical problems or blood vessel abnormalities (Gomes & Wachsman, 2013). The strokes severity and location of the brain that is affected determines the impact of the stroke in an individual (Gomes & Wachsman, 2013).(Gomes, 2013)

Stroke, or brain attack, is the number four killer of adults in the world. In the United States, 160,000 deaths occur each year. From 1999 to 2009, the death rate from stroke gradually lowered as improvements to medicine and testing developed. Yet, 800,000 Americans continue to have strokes and survive the event. Worldwide, about 15 million experience stroke with 6 million who die and 5 million who become permanently disabled. (Robinson, Richard & Odle, Teresa G. & Frey, Rebecca J. & Odle, Teresa G. , 2011) The statistics in America are better for surviving a stroke because of rapid response and better interpretation of symptoms. Nevertheless, surviving a stroke often brings on dilapidating effects; which means a change in lifestyle and lifelong rehabilitation through physical therapy.

Sometimes known as a brain attack, a stroke occurs when blood flow to the brain stops. Brain cells immediately start to die due to the lack of oxygen and nutrients they need to function. There are two types of strokes. The most common type, called ischemic stroke, is caused by a blood clot that blocks a blood vessel in the brain. The other kind of stroke, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. Stroke is the fourth leading cause of death for Americans ("What You Need to Know About Stroke," 2013). In fact, according to the CDC, more than 795,000 people in the United States have a stroke every year ("Stroke Facts," 2015). A stroke can cause great damage in the brain and lead to mild or severe

Ischemic strokes are the most common form of stroke, with around 85% of strokes being of this type. They are caused by the arteries that connect to the brain becoming blocked or narrowed, resulting in ischemia - severely reduced blood flow.

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

According to the 2011 update on U.S. stroke statistics from the American Heart Association (AHA), a stroke occurs approximately 800000 people are attacked by stroke each year in the United States, which means to one incident of stroke every 40 seconds.

Cerebrovascular Accident or stroke as most might recognize it, is a condition in which brain tissues does not get enough blood flow or oxygen. Cerebrovascular Accident has been around for quite some time. It dates back about thousands of years ago and was discovered by a man named Hippocrates. Hippocrates was a Greek physician who lived during the Classical Era of Greece. During this time little was known of the brains anatomy and its functions. For the Greeks it was called apoplexy. Apoplexy causes was a mystery until a man by the name Jacob Wepfer, a Swedish pathologist, postulated that apoplexy was caused because of excessive bleeding in the

The most common cause of a stroke is by a blocked artery, or ischemic stroke. Ischemic strokes account for 85% of CVA’s. (Stroke, Symptoms and Causes, 2017) There are two types of ischemic strokes. A Thrombotic stroke is when a blood clot forms in an artery of the brain this may be caused by atherosclerosis. (Stroke, Symptoms and Causes, 2017). Atherosclerosis is when lipids such as calcium and cholesterol is built up within the lumen of a blood vessel. Which can lead to the formation of thrombi and eventually the formation of emboli. (loffelur & Hart, 2015) An embolic stroke is when an embolus breaks free from a thrombus and lodges in the arteries of the brain. Both type of ischemic strokes stop the delivery of oxygen to the affected area of the brain. (Stroke, Symptoms and Causes,

Cerebral vascular accident or stroke is a serious condition in which the blood supply in the brain is reduced or unable to give the brain tissues the proper oxygen and nutrients it needs to properly function, killing brain cells immediately if not treated and diagnosed in a timely manner.

Strokes are primarily classified as ischemic or hemorrhagic. Ischemic strokes are the most common (% of all strokes) and occur due to obstruction of a blood vessel supplying the brain; they can be further sub-classified as thrombotic or embolic, depending on the site of occlusion. Physiologically, ischemic stroke occurs is preceded by endothelial damage in cerebral blood vessels that causes inflammation and fatty deposit accumulation in arterial walls. Subsequently, this leads to a decrease in blood vessel diameter and vascular flow. In turn, reduced oxygen and glucose supply to brain tissue creates an ischemic core (where blood flow

Stroke can be a devastating medical condition of the brain and body. This common form of cerebrovascular disease can manifest in different ways, and can cause quite a few adverse side effects. The onset of a stroke can take years to develop or can come on very quickly without warning.

Stroke is a condition that occur when there is a problem with brain supply of blood. It is off two type.
