Association of lifelong exposure to cognitive reserve

Conclusions mediated by social and cognitive stimulation rather than by in life might increase brain reserve, which moderates the ex-. Genetic risk of dementia risk mitigated by cognitive reserve: a cohort study. Annals Neurology, 86(1), 68-78. doi: 10.1002/ana.25501. Trevisan, C., Rizzuto, D., Amyloïd Load in Elderly Population: Effect of Cognitive Reserve.

The cognitive reserve (CR) theory, developed in research on aging and dementia, postulates that individual differences in the cognitive processes or neural networks underlying task performance allow some people to cope better than others with brain damage, so that patients with higher CR can withstand more advanced disease before suffering cognitive dysfunction.92 Recently, the CR theory has been applied to MS patients. Cognitive reserve (CR) is a potential mechanism to cope with brain damage. The aim of this study was to evaluate the effect of CR on a cognitive training (CT) in a group of patients with dementia. Cognitive Reserve has been suggested as the mechanism linking low levels of education with greater risk of neurodegenerative diseases. This reserve, the ability of the brain to better tolerate the Differences in cognitive reserve may contribute to the wide range of likelihood of dementia in people with similar amounts of age-related neuropathology.

in future studies as a potential shared antecedent factor for dementia and frailty, and as a novel target of interventions aimed at preventing both cognitive and functional decline in older adults. Objective To examine cross-sectional effects of cognitive reserve (CR) and brain reserve (BR) on cognition across the spectrum of Alzheimer disease (AD). Methods We included 663 AD biomarker–positive participants with dementia (probable AD, n = 462) or in the predementia stages (preclinical/prodromal AD, n = 201). Relative to individuals in the lowest tertile of cognitive reserve indicator, those with moderate and high reserve were at a reduced risk of dementia. There was no multiplicative interaction between APOE‐ε4 status and cognitive reserve indicator (p= 0.113). Additive interaction was statistically significant.

The hypothesis behind all these studies of cognitive reserve or brain reserve is that some people’s brains may be more resilient to aging and neurodegeneration than others’. The study by Huang and colleagues 2 furthers our understanding in this area and there are now multiple high-quality epidemiological studies linking poorer intelligence in early life with dementia risk. 2020-09-20 · SCD with a high cognitive reserve was related to a lower risk of dementia (OR = 0.50, 95% CI = 0.25–1.00) than SCD with lower cognitive reserve. Relative to low cognitive reserve with SCD, a low grade on the cognitive reserve indicator without SCD was associated with less risk of dementia (OR = 0.31, 95% CI = 0.14–0.68).

The aim of this study was to evaluate the effect of CR on a cognitive training (CT) in a group of patients with dementia. Eighty six participants with mild to moderate dementia were identified by their level of CR quantified by the CR Index questionnaire (CRIq) and underwent a cycle of CT. A global measure of cognition Cognitive reserve appears to provide the ability to mask neurocognitive deficits, providing a protective effect against dementia risk. 2 This theory suggests that individuals with higher cognitive reserve show less cognitive and functional impairment because their cognitive networks are more efficient, capable and flexible. 3, 2012-06-04 · 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. Cognitive Reserve, Incident Dementia, and Associated Mortality in the Ibadan Study of Ageing.

Methods: 4,112 dementia-free participants (mean age = 66.3 years) from the Rotterdam Study were followed up for on average 6.0 years. 2020-09-21 · Cognitive reserve is developed by a lifetime of education and curiosity to help your brain better cope with any failures or declines it faces. The concept of cognitive reserve originated in the late 1980s, when researchers described individuals with no apparent symptoms of dementia who were nonetheless found at autopsy to have brain changes consistent with advanced Alzheimer's disease. In this study, we have demonstrated that cognitive reserve is related to dementia prevalence and baseline general and domain-specific cognitive performance in a large cohort of oldest-old participants. However, across a 5-year period, cognitive reserve was not significantly related to incident dementia or trajectories of cognitive performance. Objective To investigate the relationship between cognitive reserve (CR) and clinical progression across the Alzheimer disease (AD) spectrum. Methods We selected 839 β-amyloid (Aβ)–positive participants with normal cognition (NC, n = 175), mild cognitive impairment (MCI, n = 437), or AD dementia (n = 227) from the Alzheimer's Disease Neuroimaging Initiative (ADNI).
