Cognitive reserve in aging.
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 individual differences in how tasks are processed provide reserve against brain pathology. Cogniti...
متن کاملCognitive reserve and the neurobiology of cognitive aging.
A hypothetical construct of "cognitive reserve" is widely used to explain how, in the face of neurodegenerative changes that are similar in nature and extent, individuals vary considerably in the severity of cognitive aging and clinical dementia. Intelligence, education and occupational level are believed to be major active components of cognitive reserve. Here, we summarize the main features o...
متن کاملExploring the neural basis of cognitive reserve in aging.
The concept of reserve arose from the mismatch between the extent of brain changes or pathology and the clinical manifestations of these brain changes. The cognitive reserve hypothesis posits that individual differences in the flexibility and adaptability of brain networks underlying cognitive function may allow some people to cope better with brain changes than others. Although there is ample ...
متن کاملThe aging brain: the cognitive reserve hypothesis and hominid evolution.
Compared to other primates, humans live a long time and have large brains. Recent theories of the evolution of human life history stages (grandmother hypothesis, intergenerational transfer of information) lend credence to the notion that selection for increased life span and menopause has occurred in hominid evolution, despite the reduction in the force of natural selection operating on older, ...
متن کاملCognitive Reserve as a Predictor of Healthy Aging
Many studies point out the existence of individual differences both in the levels of age-related cognitive impairment and in the way this impairment occurs: some people can tolerate brain damage for a longer time without showing external signs of damage. The concept of cognitive reserve emerges as a useful and interesting approach to explain this phenomenon. This paper attempts to describe the ...
