DISCUSSION
Decline in cognitive function after surgery, particularly in the elderly, has been anecdotally appreciated by the profession and public for many years. It is a well established phenomenon after hip, knee, abdominal, cardiopulmonary bypass and recent research reveals it to be a surprisingly common outcome after other types of major surgery.
Cognition is defined as the mental processes of orientation, perception, memory, and information processing, which allows the individual to acquire knowledge, solve problems, and plan for the future. It comprises the mental processes required for everyday living and should not be confused with intelligence. Cognitive dysfunction is thus impairment of these processes16 .It is usually expressed

Galanakis P, Bickel H et al (2011)18 found that Postoperative Acute Confusional State (ACS) developed in 23.8% of the study sample, in 40.5% of the hip fracture group and in 14.7% of the hip joint replacement group. risk factors of ACS: higher age (OR = 1.14, 95% CI 1.07-1.22), prior cognitive impairment as measured by Mini-Mental State Examination (OR = 1.32 for each point less, 95% CI 1.06-1.64), depression (OR = 3.67, 95% CI 1.12-12.02), low educational level (OR = 3.59, 95% CI 1.14-11.25), and preoperative abnormal sodium (OR = 4.32, 95% CI 1.01-18.38). patients. They have found higher age as risk factor to develop …show more content…
In (2012)22 Postler A, Neidel J et al conducted a prospective cohort study of 60 patients older than 65 years (66.7% female, 33.3% male) who received THR. The cognitive function was measured preoperatively, one week and six months postoperatively by the mini-mental state test (MMSE). Shortly after surgery 4 patients (6.7%) developed postoperative cognitive dysfunction, which has recovered at six-months-follow-up. In 41 patients (68.3%) adverse effects were recorded. Postoperative anemia occurred as the most common adverse effects (n=32; 53.3%). They noted that during postoperative hospital stay older patients were at an increased risk for adverse effects. Rudolph JL, Jones RN, Rasmussen LS et al in (2007)23 conducted an International Study of Postoperative Cognitive Dysfunction recruited patients undergoing noncardiac surgery from 8 countries. In bivariable analysis, several vascular risk factors were significantly associated with the likelihood of delirium, including male sex, exposure to tobacco, previous myocardial infarction, and vascular surgery. After adjustment for age, tobacco exposure and vascular surgery were independent vascular risk factors for delirium. In addition, This study said male sex is at vascular risk factor and vascular
Cognitive behaviour is dysfunctional emotions and behaviours caused by damage in brain affecting part of the brain responsible for memory and all that we learn from birth- how to talk, eat etc. This means that person with dementia can forget how important it is to eat and drink. They also may lose sense of hunger and thirst. It can become problem putting client’s health at risk.
During the pre-briefing, the group collectively discussed the patient’s history, presenting issues and other influences to the patient's care. As well, during this time, the group worked to identify role expectations, protocols, timelines and other presenting issues that would require consideration, including impaired circulation/post-op bleeding, mental status or hypoxemia. Decision-making in this aspect was based on the determined role and intended learning outcomes.
A person with a cognitive disorder does not process information correctly within the brain. This results in impaired awareness and judgement, difficulty in reasoning and focusing, loss of memory and abnormal mental capacity.
The elderly population and woman are mostly at risk of having operation. Most patients who undergo
Over one-third of the surgeries in the United States are performed on patients aged 65 and older, and delirium is one of the most common postoperative complications in this population. Despite the high incidence of delirium, the syndrome often goes undiagnosed. Postoperative delirium is associated with adverse functional and cognitive outcomes, increased hospital length of stay, cost of care, and mortality rate. Knowledge of the risk factors that predict postoperative delirium will aid early identification of the patients at highest risk in order to facilitate preoperative optimization by managing comorbidities or employing targeted prevention strategies.
cognition noted during assessment of attention & memory on neuropsychological testing. It is temporary impairment in cognition associated with surgery. The diagnosis is usually made by a preoperative testing of the cognitive functions (memory, learning, attention, abstract thinking) and then assessing the degree of impairment in these
Dementia is a term used to describe the symptoms of a number of illnesses which effect the function of the brain. It is an umbrella term describing the progressive decline in a person’s cognitive ability. The type and severity of symptoms varies with each type of dementia and is usually has a gradual onset, is progressive and irreversible. (1)
There are categories of brain dementia, which are cortical and subcortical. Subcortical dementia is marked by motor disruption. An example of subcortical dementia would be parkinson’s disease. On the other hand, Alzheimer’s is an example of cortical dementia, which as previously established is marked by memory loss. Although Alzheimer’s is classified as cortical dementia, it eventually destroys cells in all four lobes of the brain thus resulting in motor disruption as well. The ventricles, the fluid filled spaces in the brain begin to enlarge as the disease develops. The symptoms of memory loss and impaired cognitive functioning in Alzheimer’s disease can be attributed to damage in the hippocampus and cerebral cortex. The earliest detection
Though we may not realize it nor want to acknowledge it, Cognitive Psychology is a part of every human 's daily life. Cognitive Psychology is the scientific study of the mind as an information processor. In a simpler definition, it is the study of how our minds interpret and process things that we either are informed of or something we take into thought. Cognitive Psychology is a part of our attention process, language use, our memory for both long and short term, perception, problem solving, creativity, and the way we think. Each of these different features are a part of how we perceive information, think, remember, and use the information we gather. Through this branch of psychology, researchers are able to observe the relationship
Decreased cerebral perfusion as a risk factor for postoperative delirium is supported by a recent study which associated low preoperative regional oxygen saturation as measured by a cerebral oximeter (Morimoto et al., 2009).
A study conducted May 16, 2005 and ended March 25, 2006, 351 patients over the age of 65 who were recruited from General and Emergency Surgical Ward of the Unit of General, Emergency and Transplant Surgery. Looked at the increase in delirium in postoperative in the elderly
In a study that was done called aging, demographics and memory study (ADAMS) it was found that older African Americans are two times more likely than older whites to develop Alzheimer or any other dementia. Some of the reasons that have been discovered as to why older African Americans are more common to have Alzheimer’s is because they are found to have higher rates of high blood pressure, diabetes, along with other vascular diseases. Some other factors that can affect who may end up with Alzheimer’s are lower level of education, and socioeconomic characteristics which are found to be more common in African Americans. In the health and retirement study (HRS) 80% of African Americans were found to have high blood pressure. Other risks that have been found to have increased risk of Alzheimer’s are those with lower educations, low income being below $18,000 a year, and
Cognitive psychology is the scientific investigation of human cognition, that is, all our mental abilities – perceiving, learning, remembering, thinking, reasoning, and understanding. The term “cognition” stems from the Latin word “
Cognition refers to the process in which people are able to acquire and comprehend various forms of knowledge through their thoughts, experiences and use of their sensory systems. This process of cognition is in itself takes various processes. It must be said as early as now that the ultimate result of cognition processes is to result in one learning. The cognitive processes are started by one having to pay attention. This
One of the most popular New Year’s Resolutions is making it to the gym and shedding off those extra unwanted pounds padded on from the end-of-year holidays that encourage over-indulgence of delicious treats and tasty comfort foods. This and many other unhealthy habits can lead to depression, anxiety and a reduced sense of self-worth. What most people do not realize is that the temptations can be lessened by having a better understanding of their brain health and its power. “Everything you are and everything you do is controlled by your brain” (Sharpbrains, 2014). Luckily, there is still hope for all of us to improve and repair our brains.
