Pathophysiology: Cerebrovascular Accident (CVA) A cerebral vascular accident (CVA) is defined as “a sudden loss of brain functioning from a disruption of blood supply to a part of the brain causing temporary or permanent loss of movement, thought, memory, speech, or sensation”(Belleza, 2016, p. 1). CVA is categorized as ischemic or hemorrhagic. Hypertension accounts for the majority of ischemic CVAs or strokes. According to the American Heart Association, ischemic strokes are “caused by narrowed or clogged blood vessels in the brain that cut off the blood flow to the brain cells”("Stroke and High Blood Pressure," 2016, p. 1). The following are the main causes of ischemic stroke:
• Thrombosis: An obstruction of a blood vessel leading to localized occlusion. A common cause is atherosclerosis, which can lead to narrowing of the diseased blood vessel. Blood flow may be restricted as platelets adhere to atherosclerotic plaque forming a clot.
• Embolism: A clot or other material that forms within the vascular system, travels from that site, and causes blockage and ischemia in distal vessels. This occurs more commonly in the heart and lungs and can lead to hemorrhagic transformation.
