Effects of Staying Active on Cognitive Abilities in Older Adults

Facebook Twitter

This resource centre aims to provide a better understanding of the impact of staying healthy on older adults' cognitive abilities. It explores why older adults should stay active and provides recommendations on how to stay active.

What are Cognitive Skills and Abilities?

Pascale Michelon What is cog­ni­tion? Cog­ni­tion has to do with how a per­son under­stands the world and acts in it. It is the set of men­tal abil­i­ties or process­es that are part of near­ly every human action while we are awake. Cog­ni­tive abil­i­ties are brain-based skills we need to car­ry out any task from the sim­plest to the most com­plex. Cog­ni­tive abil­i­ties or skills are sup­port­ed by spe­cif­ic neu­ronal net­works. In the table below you can browse through the main brain func­tions involved in cog­ni­tion. With age, some cog­ni­tive abil­i­ties tend to decline, espe­cial­ly the so-called exec­u­tive func­tions, and those cog­ni­tive abil­i­ties that are not used reg­u­lar­ly. Introduction to Ageing and Cognitive Abilities. What is Normal Cognitive Aging? Everyone experiences a “senior moment” as they get older.

What is Normal Cognitive Aging?

Episodes of misplacing keys or forgetting an acquaintance’s last name doesn’t necessarily signal a brain disease. We asked Denise Park, director of research at the Center for Vital Longevity and chair in Behavioral and Brain Sciences at the University of Texas at Dallas, what happens to the brain and cognition as we simply get older and what we can do to mitigate the effects of it. How does the brain change as it ages? How memory and thinking ability change with age. Scientists used to think that brain connections developed at a rapid pace in the first few years of life, until you reached your mental peak in your early 20s.

How memory and thinking ability change with age

Your cognitive abilities would level off at around middle age, and then start to gradually decline. We now know this is not true. Instead, scientists now see the brain as continuously changing and developing across the entire life span. There is no period in life when the brain and its functions just hold steady. Some cognitive functions become weaker with age, while others actually improve. Some brain areas, including the hippocampus, shrink in size. On the other hand, the branching of dendrites increases, and connections between distant brain areas strengthen. Age is also the biggest risk factor for many brain diseases, most of which affect brain structure and function.

Staying Socially Active May Offset Risk of Cognitive Decline. Last month, the big news from the annual Alzheimer's Association International Conference (AAIC) 2019 in Los Angeles was that various lifestyle factors may offset dementia risk.

Staying Socially Active May Offset Risk of Cognitive Decline

All told, five research studies were presented that focused on specific lifestyle interventions (e.g., regular exercise, healthy diet, smoking cessation, limited alcohol consumption, and cognitive stimulation) that appear to counteract the genetic (and overall) risk for Alzheimer's disease and dementia. The latest research presented at AAIC 2019 suggests that boosting cognitive reserves through lifestyle choices promotes a wide range of neuroprotective benefits associated with a lower risk of dementia.

New research shows the brain has the ability to function well — and even excel — in old age.

Want to keep your brain sharp in old age? Go back to school

The secret? Keep learning. "Learning is the mechanism for development no matter how old you are," said Rachel Wu, an assistant professor of psychology at the University of California Riverside and the author of research published Wednesday in the Journals of Gerontology, Series B. Wu's study took an ambitious approach: have seniors in their 60s, 70s and 80s immerse themselves in a college-like atmosphere, enrolling in three somewhat rigorous courses simultaneously.

They participated in at least 15 hours of class a week, and also did homework assignments, over three months. The results were impressive: After just six weeks, participants' scores on standardized tests assessing thinking and memory abilities were similar to a middle-age adult's scores — a significant improvement over their scores before the study began. That is, their brains functioned more like those of a person 30 years younger.
