Cognitive reserve is the idea that some brains are strong enough to fend off the assaults of aging and disease. Brain maintenance is the idea that some brains have extra power to keep working well even in the face of aging and disease.

neighbourhoods. Growing older: Quality of Life in Old Age. 2004:81– av C Sjöström · 2020 — Theories on brain maintenance, brain reserve, and cognitive reserve try to explain individual differences in cognitive performance in aging. av D Eriksson Sörman · 2015 · Citerat av 1 — Individuals with higher cognitive capacity earlier in life have been shown to have reduced densities of tangles. Thus, one interpretation could be that the cognitive reserve, as measured by prior cognitive capacity, is associated with the spread of dementia pathology in old age (Esiri & Chance, 2012). The cognitive reserve hypothesis postulates that individuals with higher IQ are able to better tolerate age-related increase in brain pathologies. On average, they In context of cognitive aging, terms used to explain good functioning despite assumed “universal” brain aging.

These discrepant brain–cognition outcomes may be partially reconciled by the concept of cognitive reserve (CR), which was proposed to account for individual differences in the cognitive or clinical manifestations of age or illness-related brain pathology (e.g. accelerated brain ageing) (Stern, Reference Stern 2002). Cognitive reserve may allow for more flexible strategy usage, an ability thought to be captured by executive functions tasks. Additionally, cognitive reserve allows individuals greater neural efficiency, greater neural capacity, and the ability for compensation via the recruitment of additional brain regions. ‘Cognitive reserve’ is the idea that people develop a reserve of thinking abilities during their lives, and that this protects them against losses that can occur through ageing and disease.

In addition, there are terms commonly used in cognitive neuroscience studies of aging, such as efficiency, capacity, and compensation.

Cognitive reserve explains why those with higher IQ, education, occupational attainment, or participation in leisure activities evidence less severe clinical or cognitive changes in the presence of age-related or Alzheimer's disease pathology. Specifically, the cognitive reserve hypothesis is that i …

Today it is widely accepted that cognitive reserve may be the secret sauce enabling some people to continue functioning when age-related brain changes, such as shrinkage or disease, set in. “Some We examined if baseline levels of cognitive reserve (CR) and of Alzheimer's disease (AD) biomarkers modify the rate of change in cognition among individuals with normal cognition at baseline (n = 303, mean baseline age = 57 years, mean follow-up = 12 years); 66 participants subsequently developed mild cognitive impairment (MCI) or dementia due to AD. COGNITIVE RESERVE IN AGING The idea of reserve against brain damage comes from the repeated observation [1-5] of individuals who manage to function clinically in the face of brain pathology. Some types of cognitive training conducted in a research setting also seem to have benefits.

2018-08-17 · Cognitive reserve is a theoretical concept that may account for the role of social isolation and its association with cognitive outcomes in later life. Therefore, we aimed to examine the relationship between social isolation and cognition in later life, and to consider the role of cognitive reserve in this relationship.
