Cells cease to function as a result of inadequate perfusion.

Trouble speaking or understanding speech.

Due to decreased oxygen, the patient experiences confusion. Without adequate perfusion, oxygen is also low, and facial tissues could not function properly without them.

General signs and symptoms include numbness or weakness of face, arm, or leg (especially on one side of the body) confusion or change in mental status trouble speaking or understanding speech visual disturbances loss of balance, dizziness, difﬁculty walking or sudden severe headache. General signs and symptoms include numbness or weakness of face, arm, or leg (especially on one side of the body) confusion or change in mental status trouble speaking or understanding speech visual disturbances loss of balance, dizziness, difﬁculty walking or sudden severe headache. Stroke can cause a wide variety of neurologic deficits, depending on the location of the lesion, the size of the area of inadequate perfusion, and the amount of the collateral blood flow. Cardiogenic emboli are associated with cardiac dysrhythmias, usually atrial fibrillation. Small penetrating artery thrombosis affects one or more vessels and is the most common type of ischemic stroke. Large artery thromboses are caused by atherosclerotic plaques in the large blood vessels of the brain. Ischemic strokes are categorized according to their cause: large artery thrombotic strokes (20%), small penetrating artery thrombotic strokes (25%), cardiogenic embolic strokes (20%), cryptogenic strokes (30%), and other (5%).Strokes are usually hemorrhagic (15%) or ischemic/nonhemorrhagic (85%).Direct and indirect costs for stroke cost $65.5 billion in 2008.Stroke is the leading cause of serious, long-term disability in the United States.About 5.6 million noninstitutionalized stroke survivors are alive today.Approximately 600, 000 of these are new strokes, and 180, 000 are recurrent strokes.Approximately 780, 000 people experience a stroke each year in the United States.Stroke is the third leading cause of death after heart disease and cancer.Cost: Estimated direct and indirect cost for 2008 was $65.5 billion (American Heart Association and American Stroke Association, 2008).Mortality: In 2004, stroke ranked ﬁfth as the cause of death for those aged 45 to 64 years and third for those aged 65 years or older (National Heart, Lung and Blood Institute, 2007), with 150,000 deaths (American Heart Association and American Stroke Association, 2008) hemorrhagic strokes are more severe, and mortality rates are higher than ischemic strokes, with a 30-day mortality rate of 40% to 80%.stroke survivors have permanent stroke-related disabilities. Morbidity: In 2005, prevalence of stroke was estimated at 2.3 million males and 3.4 million females many of the approximately 5.7 million U.S.Stroke is a worldwide phenomenon suffered through all walks of life. The membrane pumps that maintain electrolyte balances fail and the cells cease to function. The mitochondria would need to switch to anaerobic respiration, which generates large amounts of lactic acid, causing a change in pH and rendering the neurons incapable of producing sufficient quantities of ATP. At this point, neurons are unable to maintain aerobic respiration. The ischemic cascade begins when cerebral blood flow decreases to less than 25 mL per 100g of blood per minute.

The disruption in the blood flow initiates a complex series of cellular metabolic events. Asymptomatic carotid stenosis and valvular heart disease (eg, endocarditis, prosthetic heart valves).The following are the nonmodifiable and modifiable risk factors of Cerebrovascular accident: Hemorrhagic strokes are caused by bleeding into the brain tissue, the ventricles, or the subarachnoid space. This is the loss of function in the brain as a result of a disrupted blood supply.

Strokes can be divided into two classifications. The result is an interruption in the blood supply to the brain, causing temporary or permanent loss of movement, thought, memory, speech, or sensation.Cryptogenic strokes have no known cause, and other strokes result from causes such as illicit drug use, coagulopathies, migraine, and spontaneous dissection of the carotid or vertebral arteries.It is a functional abnormality of the central nervous system.A cerebrovascular accident is a sudden loss of brain functioning resulting from a disruption of the blood supply to a part of the brain.Cerebrovascular accident or stroke is the primary cerebrovascular disorder in the United States.Practice Quiz: Cerebrovascular Accident (Stroke)Ī cerebrovascular accident (CVA), an ischemic stroke or “brain attack,” is a sudden loss of brain function resulting from a disruption of the blood supply to a part of the brain.Learn about the nursing care management of patients with cerebrovascular accident in this nursing study guide.
