Effects Of The Normal Aging Process On The Brain - 995 Words

Summary One of the side effects of the normal aging process on the brain is the dilapidation of cerebral white matter, which according to previous studies correlates to poorer cognitive functioning. This research experiment is an in-depth study of the neurological components of aging in terms of white matter integrity, working memory, and cognitive function in relation to aerobic exercise. A team of scientists from various universities conducted this exercise intervention study and it spans a twelve-month period where participants were subject to a series of cognitive tests and digital imaging scans in addition to a newly implemented exercise program for one whole year. The main objective of the study was to assess and calculate the percentage (if any) of influence aerobic exercise has on cerebral white matter durability and corresponding cognitive functions in comparison to nonaerobic exercise. The researchers hypothesized to find a positive correlation between aerobic exercise and whit e matter integrity; they hoped to map these changes in particular regions throughout the brain (hypothetically) in an anterior-posterior descent. In order to assess the diffusion of white matter through specific regions of interest (ROI) in the brain measures of fractional anisotropy (FA), radial diffusion (RD), and axial diffusion (AD) were taken from each participant throughout the course of the experiment using diffusion tensor imaging (DTI). A DTI maps the structural properties ofShow MoreRelated HGH: Fountain of Youth? Essay1196 Words   |  5 PagesHGH: Fountain of Youth? What is aging? It is a question that has been puzzling doctors for centuries. In a culture so obsessed with youth, it is not surprising that science asks this question often.

In its early stages it is difficult to distinguish from normal aging. However, whether AD is a specific qualitative disorder such as an infectious process, endogenous or exogenous toxic disorder or biochemical deficiency, or whether it is a quantitative disorder, in which an acceleration of the normal aging processes occur and dementia appears as neural reserves are exhausted, remains to be seen.

Because more individuals are aging and surviving strokes and brain injuries than ever before, it is crucial to understand the effects of these cognitive disorders on the language abilities of elderly individuals. In order to understand the impacts of brain injuries of the narrative discourse, it is vital to compare the narratives produced by normally aging individuals and those producedRead MoreEssay about Alzheimers Disease1082 Words   |  5 Pagesbrains creature.

Aging is an unavoidable process, beginning at conception and ending with death. The process does not proceed at a uniform rate all over the body. As we age, the organ systems of individuals age at different rates. Our body gradually slows down in early adult life. These changes are not apparent until perhaps 50 years of age as they are not perceptible. The skeletal system gradually changesRead MoreAlzheimer s And The Most Relevant Cause Of Dementia1496 Words   |  6 PagesAlzheimer’s is a disease that is an irremediable, continuous brain neuron degenerative disease that can be asymptomatic at first and then overtime becomes symptomatic. Alzheimer’s is a gradual disease that advances in three phases: mild, then moderate, and, finally, severe (1). Symptoms appear after the age of 60 and include: the slow destruction of memory and thought processes, and ultimately ends with the absent ability to do normal everyday duties.

Alzheimers disease (AD) is a serious form of dementia that involves the destruction of brain cells, and ultimately leads to death (1). What makes AD such a frightening disease, for both the patient and their family members, is the loss of self associated with the dementia. Those afflicted with AD cant understand the changes going on within themselves. Family members are upset by the loss of the person they once knew.
