Previous studies have demonstrated a paradox: while CR is associated with a delayed symptom onset, The concept of cognitive reserve (CR) posits that once the brain reserve capacity of an individual is depleted past a certain threshold, clinical and functional deficits and symptoms will emerge. Thus, every client that you see with a brain injury went into the accident with a certain amount of protection against the ravages of dementia, old “The concept of [cognitive reserve] refers to the capacity to be resilient to age-related brain changes and the disease-related pathology in the brain without developing clinical dementia through enhanced brain network efficiency, capacity, or flexibility,” the authors, including David Bennett, MD, the Robert C. Borwell Professor of Neurological Science and director of the Rush Alzheimer's Disease Center, wrote. 2 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. If, as a result, cognitive reserve could be modified before the clinical onset of dementia (even if Alzheimer disease were present in the brain), this may delay the onset of these clinical symptoms which would, in turn, reduce the number of people affected by dementia worldwide.

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. Scientists have discovered a biological mechanism, called, ‘cognitive reserve,' that allows the brain to retain its functionality despite the onset of Alzheimer's and other forms of dementia. The concept of a cognitive reserve arose from the observations of several independent research studies.
Higher Cognitive Reserve may be linked to decreased risk for dementia Although larger studies are needed, a major research study published in JAMA neurology in 2019 of over 1600 patients in the Rush University Memory and Aging Project showed that those who scored in the highest cognitive reserve category had a reduced risk for dementia, even if they had high amounts of Alzheimer’s brain pathology at autopsy.
Cognitive reserve is therefore a promising approach to maintaining cognitive function and protecting against symptoms of dementia. The present paper evaluates evidence supporting the claim that bilingualism 2017-03-14 Early‐life factors, such as education, are important for cognitive reserve and those with more education build greater cognitive reserve. Lifelong higher educational attainment also reduces dementia risk. Cognitive reserve is not static and is affected by a number of factors.
People with higher educational levels are more resistant to the effects of dementia as a result of having greater cognitive reserve and increased complexity of neuronal synapses [11] [19]. Like education, participation in exercises, leisure and physical activities may lower the risk of dementia by improving cognitive reserve.

Cognitive reserve is characterized by a dissociation between cognitive level and brain structure, thereby reducing the impact of deteriorating brain structure on cognitive function. Cognitive reserve is therefore a promising approach to maintaining cognitive function and protecting against symptoms of dementia.
Neural Plasticity and Cognitive Reserve framework of cognitive reserve, provide not only an explanation for the variability in clinical expression of dementia but also open up ave-nues for preserving brain function in spite of pathological neurocellu-lar dysfunction.

This article is published with open access at 2018-01-09 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 effects of a pathology of dementia, may be the result of an innate gift or the effect of life experience, such as education or type of job.
