Re: Topic 2 DQ 1 Memory, perception, communication, learning, and problem solving are all cognitive abilities that can be affected by neurological disorders. Faulkner and Green (2018), describe cognition complexities by stating “The various parts of the brain must be able to learn new information, recognize familiar persons and objects, recall past experiences, and apply all of these to current thoughts and actions.” A stroke or CVA occurs when blood and oxygen flow to the brain is disrupted by either a clot or a hemorrhage in the blood vessels that supply oxygen to the brain (Faulkner & Green, 2018). Oxygen deprivation causes the death of brain cells, resulting in severe mental and functional disabilities depending on the extent of brain cell damage. After a stroke, one can lose the functional ability of one or both sides of the body, have speech and language deficits, swallowing disabilities, and memory and cognition deficits. There are two different types of strokes, hemorrhagic and ischemic. One is caused by a hemorrhage and the other by a blood clot. Hemorrhagic strokes can be caused by unmanaged hypertension, aneurysms, and arteriovenous malformations (American Stroke Association, 2021). Ischemic strokes can be caused by atrial fibrillation and atherosclerosis. Prevention of stroke starts with a healthy diet low in saturated fat and cholesterol, exercise and maintaining a healthy weight, and managing all conditions such as hypertension and atrial fibrillation by taking all prescribed medications and routinely following up with a primary care provider.
