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.
