Effects Of The Normal Aging Process On The Brain

Last year my maternal Aunt Kate passed away. She had been diagnosed with Alzheimer’s disease (AD) about eight years earlier. My maternal grandmother also had been diagnosed with AD before her death. Later this month I will accompany my 77-year-old mother to her neurologist appointment. While she has not been diagnosed with AD, she has been prescribed Donepezil (Aricept), one of the newer drugs that are thought to reduce the decline in memory in patients that have or might be developing dementia. Opportunities to learn more about AD and the effects on the brain are welcome. The Alzheimer’s Association website, ALZ.org, is filled with a wealth of this information. Especially interesting was Inside the Brain: An Interactive Tour. I

Research has proven that physical activity improves cognitive function and can also improve brain function throughout a lifespan. Moreover, staying physically active has so many benefits as well. For example, doing exercise and fitness activities help build cells and natural pathways to help reduce changes in memory loss or dementia. Also, it has so many health benefits including long-term improvements to the cognitive function as the young adult reaching mid

Cavanaugh and Blanchard-Fields (2015) state that there is research showing how brain plasticity can be enhanced through aerobic exercise (p.51). It is important that adults be active in their lives. A 30-minute walk or some type of physical activity will benefit them as the age. The text mentions a study done by Erickson and his colleagues in 2009 where they studied the effect of aerobic exercise on the hippocampus. They found that due to aerobic exercise it produced greater volume in the hippocampus. This is significant because the hippocampus is the part of the brain that is responsible for memory, emotions, and spatial functioning. The body does not only need physical activities to produce healthier cognitive functioning but also nutrients. The text identifies three nutrient biomarker patterns that are significant on the aging brain. These nutrients are vitamin B, C,D, and E, omega-3, and trans fat. the foods that belong to these nutrients are beneficial to the brain. Older adults should make an effort to include these nutrients into their diets. positive impacts these nutrients make are better cognitive functioning and greater brain

Age-related declines are not constant across brain regions. Moreover, patterns of brain aging differs among individuals. Post mortem (PM) studies cannot help in assessment of brain tissue and its components. Moreover, PM cannot provide information on dynamic process of adult brain development, and its connection with brain structure and function. MRI helps in in-vivo measurements of the brain. It was realized that there is cortical thinning as age progresses. . Some studies of cortical thickness failed to replicate stability of the primary sensory regions (e.g., calcarine cortex) (Fjell et al., 2009; Salat et al., 2004) while others found that cortical thinning in frontal and parietal lobes exceed that of the temporal and occipital regions (Thambisetty et al., 2010). It is suggested that myelin is related to shrinkage in cerebral cortex or responsible for loss of cortical volume. MRI has helped evaluate leukoaraiosis which is a change in white matter integrity that is displayed on a T2-weighted MR image as a high signal intensity area. This area is defined as white matter hyperintensities (WMH) which depicts pathological processes such as ischemic lesions, gliosis, axonal degeneration, loss of myelin, microinfarcts, and expansion of perivascular spaces (de Leeuw et al., 2001; Pantoni, 1998). WHM is observed around the borders of the ventricles and deep in the subcortical WM regions. WHM is not present in health adults until the age of 50-55 (Hopkins et al., 2006). Further,

Alzheimer’s is a disease where neurotransmitters, acetylcholine, or the brain’s chemicals break connections with other nerve cells causing the cells to die off, the effects of this are irreversible. The loss of these cells result in loss of thinking and language skills, unpredictable behavioral changes and eventually the inability to carry out the simplest tasks. Although there is no known cause for Alzheimer’s, researchers have found a genetic link. Alzheimer’s first symptoms usually appear when a person is between forty and fifty years of age. Alzheimer’s is a devastating disease that initiates in the brain, drastically decreasing the quality of life as well as life expectancy in millions of people around the world.

A study was carried out by Finkel, Reynolds, McArdle, Gatz, & Pedersen, (2003), and the findings were that adults’ fluid intelligence, which refers to the individual’s capabilities such as abstraction, problem-solving, associative memory, and inductive reasoning may diminish slightly after adolescence. Crystallized intelligence, which refers to skills such as verbal comprehension and word relationship might increase because of learning and experience as people gets older. “Measures of crystallized ability demonstrated stable or increasing levels of performance for middle age. For highly speeded task decline occurred at age 65” (Finkel, Reynolds, McArdle, Gatz, & Pedersen, 2003, p. 547). Reaction time or speed of performance seems to differ with individuals and can either diminish or remain the same. Memory is maintained through young and middle

Alzheimer’s Disease is one of the most common causes of death in the United States, and one of the most detrimental to families around the nation. This disease affects millions of people and brings a large financial burden upon the people who give support to the affected. The expenses of Alzheimer’s are so high that the disease has caused a financial epidemic through out the nation. Through research, it has been concluded that Alzheimer’s is the most expensive disease to be effected by, beating cardiac diseases and many others that are currently plaguing the nation.

When you get older one part of your brain grows with you and deteriorates as you get older. This part of your brain is called “hippocampus”. That is the reason that when you go shopping with your nanny she forgets half of the list and she also forgot to write it down. The elderly also don’t have cognitive memory because you can ask them their original cheesecake recipe and they have it written down because they can’t remember. I would advise that the elderly play regularly memory games so they can’t forget. The elderly can play luminosity which is a website that challenges your brain. It also includes memory games which are a big help for the elderly. According to an ABC news article younger people tend to remember specific details in their

“Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills, and eventually the ability to carry out the simplest tasks individuals with AD may start having symptoms their mid-60s” (nih.gov). AD is a multifactorial and progressive neurodegenerative disease. “Parts of AD, for example, increased oxidative state, amyloid plaque deposition, and neurofibrillary tangle of tau protein in the central cortex the limbic system of the brain, have been related with Alzheimer 's disease. The disease was once thought to be a natural part of aging; it is an extremely incapacitating type of mental dementia. Albeit, some dementia

Aging is considered an inevitable part of life and for the most part it can be considered a safe and exciting journey. Throughout the aging process starting from early childhood into late adulthood there are things that one looks forward to. Things like learning how to drive, getting into university, finding a career, and getting married. These goals do not occur simultaneously, rather they occur at certain stages of the aging process. However, as one continues to age and reaches into the later parts of the aging process it can lead to problems. One of these problems is Dementia, which has a common form called Alzheimer’s disease (Burns & Iliffe, 2009). Alzheimer’s disease is defined as, “a form of progressive cognitive decline due to accumulating

There is ample evidence to demonstrate that through the normal ageing process alterations to the brain in structure and function are directly related to cognitive changes (Glisky, 2007). With an increasing ageing population strategies for prevention of disease and age related cognitive decline are necessary to improve quality of life and reduce the associated healthcare costs (Australian Government Productivity Commission [AGPC], 2013). Physical exercise is known to be crucial in maintaining physiological health; it can also be used as a means of neuroprotection and assist in modifiable risk factors for improved brain health and subsequent cognitive function. This review will critically analyse current research into the effects of exercise

Why does the human brain age? Brain aging is a part of human life and a big part of society as the awareness for brain aging increases. Over time memory tends to become less efficient as we age and the neurons in the brain decreases (Bendheim, P.E. (2009). By 2050 in the US, 20 percent of the population will be 65 years or older. And as the elderly population increases, so will the incidence of age-related neurological disorders (Perlmutter, David. (2004). Therefor it is important to understand the aging brain, and how to keep the brain functioning as one ages.

Also spelled as ageing, this is generally the process of becoming old. It is the in a way the opposite of immortality. In a broader aspect, it may occur to single cells in an organism also called cellular senescence or the population of a species, known as population ageing. This process primarily affects human beings and fungi. In humans, it signifies the accumulation of various changes which occur over time. The changes include physical, social and psychological changes.

The articles by Erikson et al., Gatz, Korol et al., and Draganski et al. explore the concept of increased physical activity and/or mental activity having effects on the cognitive function and development or deterioration of the brain as we age. Although I agree that physical exercise is critical in increasing cognitive function because of the health benefits it provides, as well as the increased blood flow and circulation throughout the body, I ultimately believe that a healthy brain is not achieved solely by physical exercise or mental exercise, but both. I think there is a link between physical and mental exercise, and that the combination of these two activities creates higher cognitive functioning of the mind as well as the body. The mind and body come together and meet to make an overall healthy individual.
