ABSTRACTBackground: Cognitive training (CT) may be effective as a therapeutic strategy to prevent cognitive decline in older adults. This review evaluates CT as a preventive tool at various stages of a prevention hierarchy with specific reference to healthy older adults, “at risk” and clinical populations. It also considers the underlying mechanism of CT, namely that which suggests that CT acts via promoting neuroplasticity.Methods: Evidence for CT in healthy, “at risk” and clinical populations has been systematically reviewed elsewhere. This review re-examines several studies in each group to clarify the potential of CT as a preventive technique, with a key focus on the secondary level of prevention.Results: Studies in healthy older adults and those with mild cognitive impairment are largely positive and suggest that CT has the potential to improve cognition. However, findings in relation to Alzheimer's disease are mixed. Limitations of existing research include diverse methodologies and CT programs, small samples, insufficient focus on functional outcomes, sustainability and generalization of effects and the need for imaging data to delineate mechanisms of change. Additionally, there is limited data on those with late-life depression, despite this being an independent risk factor for dementia.Conclusions: CT offers promise as a preventive therapeutic technique in healthy older adults and particularly as a secondary prevention method for “at risk” groups. Future investigations need to focus on methodological constraints and delineating possible neuroplastic mechanisms of action. Nonetheless, CT programs may represent a viable, non-pharmacological early intervention strategy, as they are easily-implemented, engaging and promote social interaction in group settings.

Age Related Cognitive Decline

The population of older adults is rapidly increasing, as is the number and type of products and interventions proposed to prevent or reduce the risk of age-related cognitive decline. Advocacy and prevention are part of the American Speech-Language-Hearing Association’s (ASHA’s) scope of practice documents, and speech-language pathologists must have basic awareness of the evidence contributing to healthy cognitive aging. In this article, we provide a brief overview outlining the evidence on activity engagement and its effects on cognition in older adults. We explore the current evidence around the activities of eating and drinking with a discussion on the potential benefits of omega-3 fatty acids, polyphenols, alcohol, and coffee. We investigate the evidence on the hypothesized neuroprotective effects of social activity, the evidence on computerized cognitive training, and the emerging behavioral and neuroimaging evidence on physical activity. We conclude that actively aging using a combination of several strategies may be our best line of defense against cognitive decline.

Abstract Background Social isolation and loneliness have each been associated with cognitive decline, but most previous research is limited to Western populations. This study examined the relationships of social isolation and loneliness on cognitive function among Chinese older adults. Methods This study used two waves of data (2011 and 2015) from the China Health and Retirement Longitudinal Study and analyses were restricted to those respondents aged 50 and older. Social isolation, loneliness, and cognitive function were measured at baseline. Follow-up measures on cognitive function were obtained for 7761 participants (mean age = 60.97, s.d. = 7.31; male, 50.8%). Lagged dependent variable models adjusted for confounding factors were used to evaluate the association between baseline isolation, loneliness, and cognitive function at follow-up. Results Loneliness was significantly associated with the cognitive decline at follow-up (episodic memory: β = −0.03, p < 0.01; mental status: β = −0.03, p < 0.01) in the partially adjusted models. These associations became insignificant after additional confounding variables (chronic diseases, health behaviors, disabilities, and depressive symptoms) were taken into account (all p > 0.05). By contrast, social isolation was significantly associated with decreases in all cognitive function measures at follow-up (episodic memory: β = −0.05, p < 0.001; mental status: β = −0.03, p < 0.01) even after controlling for loneliness and all confounding variables. Conclusions Social isolation is associated with cognitive decline in Chinese older adults, and the relationships are independent of loneliness. These findings expand our knowledge about the links between social relationships and the cognitive function in non-Western populations.

Abstract Although cognitive training in healthy older adults (OA) has been controversial, specific and isolated cognitive skills such as semantic memory can be improved with appropriate designs. Semantic memory has been considered as a clinical marker for cognitive decline in dementia. The current study, as part of a larger touch-screen dual-language intervention program with cognitive training tools, aims to slow down the rate of cognitive decline in OA with dementia (OwD). A set of neuropsychological tests was conducted before and after the training program. After 24 training sessions over 8-12 weeks, OwD (11 females, 1 male, mean=85.8yo) improved significantly in their verbal working memory (Rey Auditory Verbal Learning Test; RAVLT) while performance of the cognitive-healthy OA (5 females, 3 males, mean=76.3yo) remained the same post-intervention. Our findings suggest that touch-screen technology can help OwD improve their semantic memory. The strengths and limitations of our game design and intervention will be discussed.

The Impact

Abstract For older adults to “age in place”, they need to keep engaged and mobile in their communities, whatever their health condition. The impact of age and cognitive decline on community mobility is a growing problem in Europe and worldwide. Engaging in occupations outside home implies being able to get to those places where activities are performed. Yet little is known regarding the types of places visited, maintained or abandoned for older adults with/without dementia. This study addresses community mobility needs through the places people visit, maintain or abandon. People with and without dementia, aged 55+, were interviewed using the Participation in ACTivities and Places OUTside the Home (ACT-OUT) questionnaire across Switzerland (n=70), Sweden (n=69) and the UK (n=128). Results show that people with dementia experience a higher rate of abandonment for more places than regular older adults. Insights about driving cessation and access to travel passes will be presented.

AbstractBackgroundThe effect of alcohol consumption on cognitive decline is not clear. We aimed to study the association between alcohol consumption and cognitive functioning controlling for functional heath status.MethodsA total of 1610 older adults with a score ≥26 on the Mini-Mental State Examination (MMSE) were followed to assess the change in scores at the 3-year follow-up. Information on alcohol consumption as well as socio-demographic, lifestyle, psychosocial and clinical factors, as well as health service use were assessed at baseline and 3-year follow-up interviews. Linear mixed models with repeated measures were used stratifying by functional status.ResultsClose to 73% reported consuming alcohol in the past 6 months, of which 11% were heavy drinkers (≥11 and ≥16 drinks for women and men). A significant decrease in MMSE scores was observed in low functioning non-drinkers (−1.48; 95% CI: −2.06, −0.89) and light to moderate drinkers (−0.99; 95% CI: −1.54, −0.44) and high functioning non-drinkers (−0.51; 95% CI: −0.91, −0.10).ConclusionsAlcohol consumption did not contribute to cognitive decline. Cognitive decline was greater in individuals reporting low functional status. Research should focus on the interaction between changing patterns of alcohol consumption and social participation in individuals with low and high functioning status.
