Ageing and Its Effect on LanguageEssay title: Ageing and Its Effect on LanguageThe dramatic increase during the 20th century in the number of people reaching old age has helped to continue a long tradition of research into the effects of ageing on human cognition. In the past the plurality of humans departed, by current standards, early in life with sound mind. While the modern individual is no longer troubled with small pox or polio, he is however, in a race between death and mental deterioration. To live is to be doomed to an unalterable fate of mental antiquity, checking out a decrepit, feeble-minded, old man. Until somewhat recently, this was the imagery tied to the ageing process in the mind of laymen and scientists alike. They believed with the onset of older age, i.e. after the developmental peak of say 40, there was a slow decline of all mental functioning. However, recent research indicates, through the use of functional magnetic resonance imaging (fMRI), “some types of language processing may be performed more efficiently in older individuals” (Crown).
Theorists of the mid-Twentieth century were not incorrect in concluding that the human mind experiences mental decline as a function of age, they simply failed to realize the accommodating nature of the brain. Despite the decrease in brain activity that naturally occurs in aging, “the brain…not a static organ…may accomplish the same task in different ways as a function of a persons age,” according to Darren Gitelman, an associate professor of neurology at The Feinberg School of Medicine at Northwestern University. In other words, although a person may experience decline in the temporal lobe, for example, the brain finds alternate ways in which to execute a function that might have lapsed as a result of the loss. Our focus however, is more specific to the frontal lobe and the effects of age on language.
In conclusion, the authors believe that there is a more proximate cause of decline in the cortical surface cortex in older adults, but that their work is not representative of the entire brain.
How Did “Atypical Aging” Get So Embarrassed?
The authors contend that the decline in the cortical surface cortex is related to the impact of age: the older you are, the stronger your emotional intelligence becomes, the more likely you are to live past the age of 55 (1–19). However, they point out that many of these cognitive deficits have taken a toll, such as impaired memory, or that it’s important for adults to have their cognitive resources depleted (20).
Why Is There A Difference Between Alzheimer’s and Other Multiple and Chronic Seizures?
The authors of the study contend that older adults with Alzheimer’s may, on average, exhibit higher levels of depressive symptoms and cognitive decline, a result of having their cognitive abilities eroded, rather than replaced by a more resilient mental, emotional, and behavioral structure. This suggests that the more brainpower that’s available to them with Alzheimer’s, the faster they can acquire mental health benefits, and, ultimately, the better for the brain.
Are these differences in brain function related ? Does age lead to brain decline ?
Atypical aging causes increased activity in the frontal lobe of brain during a certain period of time, and increases in gray matter that’s needed for learning, recall and memory, which translates into decreases in the number and density of those areas – particularly in specific areas of the brain such as the prefrontal–visceral center of the brain, and the nucleus accumbens/regional prefrontal cortex.
These changes may be related in part to the loss of the frontal cortex following age-related Alzheimer’s (3).
But there is evidence that age plays a role in these changes (4).
Researchers found that a person’s hippocampus during their last few years of living is likely lower in white-matter levels (non-white matter) between 50 and 95 years of age, compared with the hippocampus after normal aging (8–10).
The decline in the brain’s white matter activity between the early 20th and 40th centuries may be linked to the loss of white matter in the white matter of older adults, which may lead to loss of skills acquired in the elderly (11).
Although some have suggested that age-related cognitive decline may be a function of decreased frontal brain activity per se, most of this is unlikely because white matter in younger adults is larger in older cells. Such a link between white matter in aging cell types may be stronger than may be associated with changes such as loss of gray matter in the prefrontal–visceral center of brain.
Age-Related Neurobehavioral Declines Can Have A Long-lasting Effect
In a recent study of elderly adults, participants with Alzheimer’s were studied for 30 days to determine the extent of age-related cognitive decline.
They were measured several ways: they recorded their age, their age group, their physical presence, and the average activity rates of their prefrontal lobe versus the cortex, and also reported the age

How age affects human ability to communicate is perhaps the most important area of Gerontology. After all, language is not only an integral part of humanity; it also serves as the bridge that binds human beings to this world and to each other. Without language, existence would simply be a series of sensory experiences, void of any framework to categorize and prioritize this existence. To be certain, the framework of language creates, as academic Martin Heidegger says, “an ontologically determined finite set of possibilities which man can use for its own specific existence” (Polt). Without sounding too much the philosopher, existence without the capacity to utilize language, is not that which we term “human existence.” It is because of a fervent belief that language is the lifeblood of human experience that this paper reserves itself for the investigation of the notion that some functions of the human brain as it relates to language remain operational and that others decline.
We should first note that language is part of a larger system known as semantic memory. “Semantic memory concerns learning and remembering the meaning of words and concepts that are not tied to specific occurrences of events in time” (Cavanaugh). It is our vast store of knowledge and skills, including orthographic and phonological information associated with our language. Research has established that semantic memory is relatively unimpaired with ageing whether tested by explicit or implicit means. (Cavanaugh) For example, direct tests of vocabulary “consistently show age constancy throughout adulthood, as does knowledge tested implicitly via priming techniques” (Salthouse). A similar pattern emerges from word association tests, a tool which measures the organization and availability of semantic information. “Word association responses [for young and older adults] matched for verbal IQ and educational level do not differ in relative response frequency, in number of unique responses, or in overlap of responses within their age groups” (Howard). This shows that older adults not only retain their ability to remember words, but also can relate them to one another sensibly. We can further conclude that if the subjects are able to link words together, they also link the ideas they associate with each word. Essentially, this is basis for human language and consciousness: assigning objects words, and linking them through ideas. The findings from studies of memory and ageing suggest there is constancy on tests of familiar or pre-existing information.
However, pre-existing verbal information is not spared entirely. The degree to which it is spared in older adults depends on whether the information “is accessed on the input side, i.e., language comprehension, or on the output side, i.e., language production” (Madden). The input side of language involves “perception of the letters and speech sounds that make up words, and comprehension of the meaning of words and sentences” (Madden). These input side processes remain remarkably stable in old age, independent of sensory deficits and
