Education and Dementia in the Context of the Cognitive Reserve Hypothesis: A Systematic Review with Meta-Analyses and Qualitative Analyses. June 2012
Remaining cognitively active can reduce cognitive decline. One of the most influential perspectives on cognition during middle adulthood has been that of the
A novel model of the cognitive reserve hypothesis and use-dependency theory is 2012-06-04 · The Cognitive Reserve Hypothesis. The concept of brain reserve or cognitive reserve (CR) refers to the ability to tolerate the age-related changes and disease related pathology in the brain without developing clinical symptoms or signs of disease . Cognitive reserve may be based on more efficient utilization of brain networks or of enhanced ability to recruit alternate brain networks as needed. A distinction is suggested between reserve, the ability to optimize or maximize normal performance, and compensation, an attempt to maximize performance in the face of brain damage by using brain structures or networks not engaged when the brain Objective To investigate the relationship between cognitive reserve (CR) and clinical progression across the Alzheimer disease (AD) spectrum.
The construct of cognitive re-serve refers to individual differences in brain structure (e.g., density of neuronal synapses) and function (e.g., processing efficiency) thought to buffer the effects of neu-ropathology. Evidence has emerged from the rapidly evolving field of cognitive epidemiology (2) showing that 2016-08-01 · These findings are consistent with studies suggesting that for those who subsequently develop dementia, a high level of premorbid cognitive activity is associated with delayed symptom onset, followed by an accelerated course of decline [93–95], as is predicted by the cognitive reserve hypothesis. Cognitive reserve proxies, including education, are not associated with cortical atrophy [40, 41] or functional activity , but cognitive reserve has a negative association with brain volumes . Researchers in one study reported that higher cognitive reserve, including education, is related to more severe hypometabolism in MCI . Cognitive reserve theories have been postulated in an attempt to explain individual differences in functional outcome following cerebral insult or disease. These theories suggest that higher education and psychometric intelligence may preserve functional capacity regardless of injury or disease severity.

The cognitive reserve hypothesis, however, emphasizes functional aspects such as more efficient and flexible usage of the existing neural network. 2 Cognitive reserve is the idea of building up additional abilities to compensate for the possibility of declining memory or thinking. Think of it as over-training to run a race. The race itself may be a 10-kilometer race, but you might practice by running 12 kilometers to build up your endurance and strength. The cognitive reserve hypothesis is 238 based on the observation that the actual cognitive performance is often not concordant with 239 the existing neuronal injury.

In this article. By American Geriatrics Society (AGS), Health in Aging Foundation. The cognitive reserve theory essentially says that people who have a larger reserve of neurons and stronger cognitive abilities can tolerate some brain deterioration without showing symptoms. This theory resulted from a study published in the Annals of Neurology in the late 1980s, which raised questions about why some people develop symptoms of Alzheimer’s disease and some don’t.
