Fear of losing one's cognitive ability to Alzheimer disease and related dementias (ADRD) and ultimately declining to a state considered by many to be worse than death (1) is driving a growing brain-training industry. Cognitive training programs, marketed to otherwise healthy adults and persons with a recent diagnosis of mild cognitive impairment (MCI), make bold claims for reversing brain aging. Such claims include the ability to boost cognitive reserve in midlife (with cognitive reserve… Expand
Mild Cognitive Impairment in Clinical Practice: A Review Article
TLDR
Lifestyle modification, such as aerobic exercise, is an approved modality to preserve cognitive ability and decrease the rate of progression to dementia, as well as being recommended for frailty prevention. Expand
Lifestyle Modifications and Nutritional Interventions in Aging-Associated Cognitive Decline and Alzheimer’s Disease
TLDR
Insight is provided into the role of non-pharmacologic interventions in the modulation of AD pathology, which may offer the benefit of improving quality of life by reducing cognitive decline and incident AD. Expand
Reconsidering the overdiagnosis of mild cognitive impairment for dementia prevention among adults aged ≥80 years
TLDR
It is necessary to increase patients’ health literacy, which requires medical professionals to provide them with appropriate evidence-based information, and it is important to provide psychological support to people who have been diagnosed. Expand
Technologies for Cognitive Training and Cognitive Rehabilitation for People With Mild Cognitive Impairment and Dementia. A Systematic Review
TLDR
The studies found on cognitive intervention software indicate the existence of various technological programs for people with MCI and dementia, but more information about the features and context of use is needed as well as more clinical studies to be able to compare among computerized cognitive programs. Expand
A Multifactor Approach to Mild Cognitive Impairment
TLDR
Different conceptions of MCI are reviewed, the diagnosis and prognostication ofMCI, and presently available management approaches for this condition are reviewed. Expand
Promoting Successful Cognitive Aging: A Ten-Year Update.
TLDR
There is a growing consensus among major health organizations about recommendations to mitigate cognitive decline and promote healthy cognitive aging, and practical advice about behavior-change techniques to help patients adopt brain-healthy behaviors is offered. Expand
Nutritional prevention of cognitive decline and dementia
TLDR
The evidence for the effects of some dietary components, supplements, and dietary patterns as neuroprotective, with potential to delay cognitive decline and the onset of dementia are evaluated. Expand
Biopsychosocial reserves and dementia: Identifying life span protective factors
Dementia is a neurocognitive disorder that negatively affects independence and significantly contributes to the global mortality rate. Alzheimer’s disease is the most pervasive type of dementia andExpand
Is Computerized Working Memory Training Effective in Healthy Older Adults? Evidence from a Multi-Site, Randomized Controlled Trial.
TLDR
Home-based CCT Adaptive WM training appears more effective than Non-Adaptive training in older adults from different cultural backgrounds, and evidence of improvement in trained tasks and on a demanding untrained task dependent upon WM and processing speed is presented. Expand

Cognitive training and cognitive rehabilitation for mild to moderate Alzheimer's disease and vascular dementia.
TLDR
Evaluated cognitive training and cognitive rehabilitation for people with mild Alzheimer's disease or vascular dementia found promising results in relation to a number of participant and caregiver outcomes, and was generally of high quality. Expand
Interventions to Prevent Age-Related Cognitive Decline, Mild Cognitive Impairment, and Clinical Alzheimer’s-Type Dementia
TLDR
The challenge is to identify any interventions that can lead to reductions in dementia incidence and make them more widespread. Expand
Cognitive rehabilitation and cognitive training for early-stage Alzheimer's disease and vascular dementia.
TLDR
The present findings do not provide strong support for the use of cognitive training interventions for people with early-stage AD or vascular dementia, although they must be viewed with caution due to the limited number of RCTs available and to the methodological limitations identified. Expand
Preventing Alzheimer's disease and cognitive decline.
TLDR
The current research on the list of putative risk or protective factors is largely inadequate to confidently assess their association with AD or cognitive decline, and further research that addresses the limitations of existing studies is needed to be able to make recommendations on interventions. Expand
Positive effects of computer-based cognitive training in adults with mild cognitive impairment
TLDR
Cognitive training based on recognition holds promise as a preventive therapeutic method and could be proposed as a non-pharmacological early-intervention strategy and future investigations need to focus on methodological constraints and delineating possible neuroplastic mechanisms of action. Expand
The PACE study: a randomized clinical trial of cognitive activity strategy training for older people with mild cognitive impairment.
TLDR
The devised program of CA did not improve general cognitive performance of older adults with MCI over a period of 2 years, and the beneficial effects of the intervention on attention and quality of life were small, and of uncertain significance. Expand
Memory enhancement training for older adults with mild cognitive impairment: A preliminary study
TLDR
It is suggested that individuals with MCI can benefit from multi-component memory enhancement training and further development of such training programs and tests of their efficacy alone and in combination with medications are needed. Expand
Cognition-based interventions for healthy older people and people with mild cognitive impairment.
TLDR
There is evidence that cognitive interventions do lead to performance gains but none of the effects observed could be attributable specifically to cognitive training, as the improvements observed did not exceed the improvement in active control conditions. Expand
Long-term observation of a multicomponent cognitive intervention in mild cognitive impairment.
TLDR
Benefits of the 6-month cognitive intervention on global cognitive status appear to be preserved over extended follow-up periods, and early cognitive intervention may delay conversion to Alzheimer's disease. Expand
Effects of a 6-month cognitive intervention on brain metabolism in patients with amnestic MCI and mild Alzheimer's disease.
TLDR
A six-month cognitive intervention imparted cognitive benefits in patients with aMCI, which were concurrent with an attenuated decline of glucose metabolism in cortical regions affected by neurodegenerative AD. Expand
