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.

T2 - a cognitive reserve hypothesis. AU - Florio, T. AU - Trollor, J. N. Hypothesis 5 (the association between brain atrophy and cognitive decline will be stronger in persons with low reserve than in persons with high reserve) A second random effects model was estimated to address whether Mem-R moderated the effect of baseline Mem-B on longitudinal change in executive function. work efficiency and capacity (neural reserve) or compen-satory functional brain differences (neural compensation) may account for such a higher reserve ability [16, 17]. Thus, according to the cognitive reserve hypothesis, protective life factors such as education miti-gate the impact of brain pathology in cognition.

BACKGROUND: Recent attention in the literature has been brought to the cognitive reserve hypothesis in understanding variation in functional outcome after brain injury.

Cognitive reserve hypothesis

The construct of cognitive reserve 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 neuropathology. The Cognitive Reserve Hypothesis: A Longitudinal Examination of Age-Associated Declines in Reasoning and Processing Speed Elliot M. Tucker-Drob 1 , Kathy E. Johnson 2 , and Richard N. Jones 3 The concept of cognitive reserve provides an explanation for differences between individuals in susceptibility to age-related brain changes or pathology related to Alzheimer's disease, whereby some people can tolerate more of these changes than others and maintain function. ropsychiatric disorders (1). 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 .

The number of synapses is lower in early onset dementia than in late onset dementia. Genetic component of cognitive reserve. Cognitive Reserve Traumatic Brain Injury, Part I. Cognitive reserve is thought to play a significant role in the development and clinical Cognitive Impairment in Multiple Sclerosis.

"If the cognitive-reserve hypothesis is correct, memory decline will accelerate closer to the time of dementia diagnosis and that decline will be more rapid in persons with more education," they

Psychology Today shared the hypothesis of a brain study that is being conducted from 2016-2018 – and Brain and Cognitive reserve concept is a theoretical general framework Literature supports the hypothesis that reserves impact on neurodegenerative process Cognitive reserve is commonly used to refer to both brain and cognitive reserves in onset Alzheimer disease: implications for the cognitive reserve hypothesis. According to this hypothesis, AD patients with higher CR than those with lower CR require a greater accumulation of damage from brain pathology in order to show The cognitive reserve hypothesis posits that these active changes develop in response to education and other cognitive stimuli throughout a person's lifetime.

Nov 20, 2019 Cognitive reserve refers to the capacity of the brain to withstand changes due to age or disease-related pathology that typically leads to a

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 A clinical model, “the cognitive reserve hypothesis,” proposes that both increased brain volume and enhanced cognitive ability may contribute to healthy brain … In popular psychology the use-it-or-lose-it theory has become accepted; that is, an increase in cognitive activity, particularly in later life, can reduce cognitive decline associated with both pathological and healthy aging. In the field of cognitive neuropsychology, the use-it-or-lose-it theory can represent either the cognitive reserve hypothesis or use-dependency theory.

Background: The cognitive reserve hypothesis describes a hypothetical mechanism to cope with brain damage: individuals with high reserve are thought to tolerate more Alzheimer neuropathology before symptom onset, show greater neuropathology at time of onset, and experience shorter survival post onset. This study assessed the association On the basis of the cognitive reserve hypothesis, we predicted that both patients with SVaD and patients with svMCI would show a negative correlation between education and cortical thickness or a positive correlation between education and CSVD MRI markers when controlling for cognitive status in each group. cognitive reserve hypothesis.

In the field of cognitive neuropsychology, the use-it-or-lose-it theory can represent either the cognitive reserve hypothesis or use-dependency theory. The cognitive reserve hypothesis states that an individual must be relatively cognitively active throughout life (particularly in early life) in order to build up a cognitive reserve to counter cognitive decline in old age.

Early life experiences such as This reserve could be innate and people with greater reserve would be prone to have more education. The cognitive reserve hypothesis, however, emphasizes functional aspects such as more efficient and flexible usage of the existing neural network.

Abstract. Background: Cognitive reserve (CR) or brain reserve capacity explains why individuals with higher IQ, education, or occupational attainment have lower risks of developing dementia, Alzheimer's disease (AD) or vascular dementia (VaD). The CR hypothesis postulates that CR reduces the prevalence and incidence of AD or VaD. The brain or cognitive reserve (BCR) hypothesis states that high premorbid intelligence, education, and an active and stimulating lifestyle provide reserve capacity, which acts as a buffer against the cognitive deficits due to accumulating neuropathology. This reserve could be innate and people with greater reserve would be prone to have more education. 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.
