Cognitive effects of aging
Don’t take our word for it - see why 10 million students trust us with their essay needs.
As a person grows old, it is inevitable to have both physical and cognitive changes happen throughout their lifetime. In an average life span, a person’s physical and cognitive changes will normally vary depending on what age group they are in. For example, it is said that from birth to age five, a child will absorb more information including how to talk, language, form relationships, and fine motor skills than any other age. It is also said that that most rapid decline in physical ability is in older adults ranging from a loss in eyesight to severe dementia. In my life right now, I most strongly identify with cognitive function. As a college student, I am always using my brain to learn new information and retain new material. I am always paying attention to my surroundings and making sure I know what’s going on around me in my academic and social life. There is rarely a time when I feel like my brain is “turned off.” If I am not thinking about something related to my …show more content…
After hearing what my mother had to say, I feel that when I am at an older age, my physical function may become more what identifies me than my cognitive function. It seems as if once your physical ability stops you from doing what you were once able to do, it identifies you more than your cognitive ability. For my mom, she still has most of her cognitive function, so that has not changed her much throughout the years. For me, my physical ability has stayed the same for many years, so that has not impacted me much. On the other hand, my cognitive ability has increased over the years, making it what identifies me the most. These two functions will change a person throughout their lifetime, but depending on what age the person is at can change the impact these functions have
During late adulthood, which begins around 65, many changes will take place. Death, sickness, and aging are some of the things you go through. Everyone is affected at some point. Individuals deal with these changes differently. Gerontology is the science that deals with the aging process. Vision can show impairment as people age. One of the changes in vision is the loss of accommodation of the lens. Most people 65 and older have hardened eye lens and have lost elasticity if the lens. Cataracts can form and vision becomes cloudy and is significantly impaired. Glaucoma is a serious condition that causes pressure to increase within the eye and it can result in blindness. Often hearing decreases with age. The hair cells in the Corti (inner ear) can cause a decrease in hearing frequencies. The ossicles and eardrum have a decrease in the transmittance of mechanical sound waves. Due to aging many elderly people have hearing impairment. Loss of appetite from connective tissue cells replacing taste buds. Skin can become thin, dry, and inelastic as it ages and the skin can fold and wrinkle from sagging.
...tions in the number of synaptic spines and functional synapses contribute to annual reductions of as much as 0.5% to 1.0% in cortical thickness (the cortex is the outermost layer of the brain) and sub-cortical volume in some regions of the brain (Fjell & Walhovd, 2010). Working memory declines in both speed and function, so they forget names, locations of important objects, appointments and medication schedules (Smart, 2012). Both physical fitness and exercise in the form of stimulation among multiple channels aid in slowing cognitive decline and could potentially provide success to individuals (Whitbourne & Whitbourne, 2010). However, Horn and Cattell found that memory, crystallized intelligence, and fluid knowledge all decreased after age of 70 despite level of education, physical activeness and the number and variety of stimulating experiences (Smart, 2012).
Many countries globally are faced with unprecedented demographic changes from high mortality and fertility to low mortality and fertility, giving rise to an ageing population. Population ageing is profound and enduring, and has major consequences and implications for all facets of human life. With a larger proportion of older people, one of the major concerns is health and health care. The health of older persons generally declines with age and some illness are more likely to be associated with older people. One of such illness is dementia. As the life expectancies of the general population have dramatically increased since the turn of the century, more and more people are at risk of developing a dementia (National Institute of Aging, 2000).
Late Adulthood is the last stage of human lifespan development. Human beings are complex in many ways that it is essential that we human understand these crucial development stages in our life to better communicate and prepared for them. At this stage of development, organs in adults work differently or maybe slowly. For example, I observed that when someone is approaching my grandma from a far distance, it is hard for her to identify or sometimes seems blurry to see who the person is even if it is someone she knows, until the person move very close to her before she is able to identify the person; this is as a result to low vision related to aging.
Aging occurs at the biological, psychological and social levels. With numerous theories of aging spanning over many disciplines, no one is truly certain why we age or how we cope with it. Fortunately, our knowledge of how the body regulates or governs the rate of aging is slowly being demystifyied and we now know more about this process. Activity and disengagement are two major psychosocial theories which describe how people develop in old age.
Aging occurs in every species. Over time a change occurs on a cellular level in a person’s body, which causes degenerative effects on the brain, muscles, organs, bones, hormones, and DNA. In 1991, the book Evolutionary Biology of Aging, offered the following definition of aging: a persistent decline in the age-specific fitness components of an organism due to internal physiological deterioration.1 Aging affects the body physically and mentally. Many people dread getting older due to the numerous changes the body goes through. The geriatric population experiences many pains and is inflicted with various diseases. There are a few who are lucky enough to not get diagnosed with a life altering disease, such as Alzheimer’s, type II diabetes, high blood pressure, macular degeneration, or some form of cancer. Studies have shown that genetics play a vital role in the aging process.
I was surprised to learn that successful aging is a combination of physical and functional health, high cognitive functioning, and active involvement with society. It was interesting to learn that these factors could lead to a lower risk of disease and disability. As
The first cognitive ability is Fluid reasoning also known as Fluid Intelligence is our mind’s ability to figure out a situation and then to think quickly and process an answer to that situation, this ability also applies to long term memory as well. He continued to tell me cognitive abilities are brain based skills we use to perform simple tasks to more difficult ones. They are closely related to how we learn, remember things, solve problems and pay attention rather than with any prior knowledge to the subject. He also explained that there are 7 main cognitive functions perception, attention, memory, motor skills, language, visual, spatial processing and executive functions he told me I will only go into detail on the important ones. Perception is our response to things we recognize and interpret like our sense of smell. Attention is one’s capacity to maintain concentration on an object action or thought. Memory is the ability to remember long term and short term
This paper is on dementia, a late-life disorder, as it pertains to the geriatric population. “It is estimated that 24.3 million people around the world have dementia and that, with an estimated 4.6 million new cases every year, we can expect about 43 million people and their families to have to handle the challenge of dementia by 2020.” (McNamera, 2011) I will cover three relevant points concerning this disorder that cause changes in the brain.
Developmental health psychologists - specialists who study the interaction of age, behavior, and health and gerontologists - specialists in the science of aging -- are piecing together the details of diet, exercise, personality and behavior that make it practical to shoot for 80, or even 120. People approaching middle age can expect a bonus of several years of extra living thanks to continuing medical progress against cancer, heart disease and stroke. Specialists in the field of aging, developmental health psychologists, and gerontologist , concentrate their area of study on determining health status over the course of adulthood, and determining the nature and origin of age-related diseases. They are also concerned with describing the effects of health on behavior and describing the effects of behavior on health. The goals of these specialists are: prevention of diseases, preservation of health, and improved quality of health for those suffering from disability and disease.
Intelligence has been commonly thought to decline as we get older, however this is a flawed belief. Countless individuals will argue that there are various cognitive processes that are associated with changes in the brain that do deteriorate with time, however there are also other brain areas that increase their activity in older age. I believe a person’s ability to perform certain tasks may become slower as they get older, but this doesn’t automatically mean that they are cognitively getting less intelligent. There are numerous ways in which intelligence can be defined, although it is commonly defined as general cognitive skills, this means that it is a mental ability involved in the capacity of learning, reasoning, perceiving relationships and analogies, understanding, facts, meanings, etc. (Dictionary definition). However Raymond Cattell (1963) argued that ‘intelligence does not generally consist of only cognitive performance’. Cattell and Horns theory developed in 1966 and emphasises that intelligence is composed of a number of different abilities that interrelate to form the broad term of intelligence. The main two factors are crystallised and Fluid intelligence.
Throughout this course I have learned a lot about psychology. I will talk about how it affected me personally, socially, organizationally/societal, and the lasting impact it had in my life.
Some people belief that when they are old, their cognition will decrease, especially in decision-making and learning new things. On the contrary, older people have a wise brain and perfect skill because different skill of Cognition which is the process of knowing and understanding (longman dictionary) will peak at different time, some is soon while some take a longer time. Besides as people are ageing they have more experience as well as more knowledge to increase their ability to learn, that why we have a sayings like” the older, the wiser”. Furthermore, our brain is working as the same as our skin or body if only they take care of their brain in the right way they can keep their brains sharp for a certain extra time.On the other hand, people
I was working within the cognitive dimension of literacy. I was transacting with the book while using mental processes and strategies to construct meaning. While transacting with the text I was using the sociocultural dimension by using and creating background knowledge to connect what I was reading about to my life, and what I learned about World War II and the Holocaust in social studies class. I was using the cognitive dimension of literacy, I was able to read the words on the page to create meaning that I could then connect to my background knowledge about the subject.
Reading, the active learner is reading different king of materials such as book, journals, newspaper and so on. Through reading, the people acquire different knowledge and make its application in life.
