This aim of this essay will be to summarise what a stroke is, including the structure and functions that are pathologically affect by a stroke. Next this essay will discuss the negative impact a stroke could have biologically, psychologically and socially on a person’s health. Finally this essay will demonstrate the application of theoretical concepts to practice in relation to a stroke.
A stroke also known as a cerebrovascular accident (CVA) happens when the blood supply to part of the brain is cut off and brain cells are damaged or die. For the brain to function, it needs a constant blood supply, which provides vital nutrients and oxygen to the brain cells (NHS, 2013).
When brain cells die during a stroke, the functions controlled by that area of the brain are lost. These functions include speech, movement and memory. How a stroke patient is affected depends on where the stroke transpires in the brain and how much the brain is damaged (The National Stroke Association, 2014).
There are two types of stroke the first being a Haemorrhagic stroke, this where a there is a bleed on the brain due to a burst blood vessel within the brain. The other is an Ischemic strokes, this occurs due to an artery leading to the brain being blocked. Ischemic strokes are split into two types: Embolic and Thrombotic (The internet stroke centre, 2014).
An embolic stroke is where a blood clot forms elsewhere, usually in the heart, and travels in the bloodstream, in the larger arteries, until it become lodged within a smaller artery (Bupa, 2013).
A thrombotic stroke happens due to a cerebral artery being blocked by a thrombus. A thrombus is caused by the build-up of fatty deposits in the artery walls, causing the artery to become narrower therefore reducing the blood flow. Eventually the artery becomes completely blocked restricting the blood from reaching the brain. This causes the functions controlled in the area where the stroke attacks to be damaged or die. Thrombotic strokes...
