Unit 4 Capstone Project : Cerebral Vascular Accident

     The most common causes of strokes are thrombosis. This is when a clot forms in one of the arteries, mostly in the carotid in the neck and the vertebral artery. The blood is thick and moves very slowly through the artery. The thrombus will form on the damaged area of the artery wall and will cut off the flow of blood to the brain. The area of the artery that is damaged is cause by arteriosclerosis. This form of

There are two major branches of strokes: those caused by narrowing or blockage of the arteries leading towards the brain, and those caused by blood vessel leaking or rupturing in the brain. Ischemic strokes account for approximately 87% of Stroke cases, which reduces the blood flow to the brain. About half of the Ischemic strokes are caused by clotting in small or large arteries, a smaller portion are caused by

An ischemic stroke is typically caused by a thrombosis, which is a blood clot or an embolism, when the blood clot detaches and infiltrates the blood stream.

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 is the sudden death of brain cells in a localized area due to inadequate blood

According to our American Red Cross Nursing Assistant text a cerebral vascular accident, C.V.A., or stroke occurs when blood flow to a part of the brain is interrupted. The loss of blood supply results in the death of brain cells. (Page 91) When your brain starts to die the bodily functions the brain controls can be affected. The affected bodily functions depend on what part of the brain does not receive oxygen. Web MD says damage “can occur within 3-4 minutes if not treated.”

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

The stroke from a blocked artery is called ischemia, and the ruptured artery is hemorrhagic. As time is critical after the cerebrovascular accident, lack of treatment will lead to brain cell apoptosis and neural injuries are permanent. Evaluation using brief tests of cognitive impairment includes analysis of executive functioning, memory, language, and visuospatial performance, neuropsychiatric as well as depressive symptoms (Grant and Adams, 2009).

The diagnostic process for a formally diagnosing Cerebral Vascular Accident (CVA/stroke), would consist with a number of test including a physical exam and questions regarding your family history of strokes, any signs or symptoms that may have been present before the patient had the stroke. The physician would also order a few tests like a MRI, CT scan, Cerebral Carotid ultrasound, Cerebral Angiogram and an Echo Cardiogram. The physical exam is important to listen to the hearts sounds, take your blood pressure and also use a ophthalmoscope ( a scope to look in your eyes, ears and nose) to see if there are any cholesterol crystals behind the eyes("Diagnosis - Stroke - Mayo Clinic," 2015). A MRI, uses radio and magnetic waves to show a detailed

Cerebrovascular Accident- condition in which brain tissue is deprived of blood supply.  The most common stroke symptoms are:

A CVA occurs when a part of the brain is damaged or destroyed due to an interruption of blood flow to the area resulting in brain cell death (Martini, Nath & Bartholomew 2015 pp. 496-470).There are two main types of a CVA, Ischaemic stroke and Haemorrhagic stroke (AIHW 2013). The most common cause of stroke is ischaemic, which can be caused by embolism/thrombosis (AIHW 2013). An embolism/thrombosis occurs when there is a clot in an artery or vein, which stops blood flow to the brain (AIHW 2013). A haemorrhagic stroke is when an artery ruptures and bleeds into the surrounding brain tissue (AIHW 2013). This form of stroke occurs when blood pools and forms a clot therefore putting pressure on the area of the brain depriving it of oxygen and nutrients it needs to remain healthy (AIHW 2013).

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

The topic assigned to me for the health paper is cerebrovascular disease, which is a stroke. Cerebrovascular is really two words combined. Cerebro is the largest part in the brain and vascular is termed as veins and arteries. From those two terms, one can interpret that this disease has to deal with the blood flow that goes on in the brain. According to the Association of Neurological surgeons, cerebrovascular disease is defined as the any disorder that is in the brain is either permanently or temporarily affected by bleeding and even by ischemia (AANS, 2005). It states, “ Cerebrovascular disease includes stroke, carotid stenosis, vertebral stenosis and intracranial stenosis, aneurysms, and vascular malformations” (AANS, 2005). When this

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

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
