Summary: This study explored the effect of dance on cognitive function in older adults and found that dance probably improves global cognitive function and executive function. However, the impact on complex attention and learning and memory is minimal. Future research is needed to determine the optimal dose of dance intervention and to compare cognitive benefits between dance and other types of physical activity.

Summary: A systematic review and meta-analysis found that acute ingestion of Guarana has a small positive effect on human cognitive performance, improving response time but not accuracy. Whether the changes in cognitive performance are related to the caffeine content or other bioactive substances in Guarana remains unknown and requires further research.

Summary: This meta-analysis examined associations between objectively measured sleep parameters and cognitive performance in healthy older adults. It found that both sleep macrostructure and microstructure were related to cognitive function. The relationship between sleep and cognition was moderated by age, education, and percentage of female participants. This study highlights the importance of objective sleep measures in understanding the relationship between sleep and cognition in healthy older adults.

Summary: This article investigates the potential benefits of yoga for older adults with mild cognitive impairment (MCI) and dementia. The studies suggest that yoga may be safe and beneficial for the wellbeing of individuals with MCI or dementia, with improvements in cognition, mood, and balance reported. However, the high risk of bias in the studies limits the robustness of these findings. More high-quality randomized controlled trials are needed to improve the evidence base and address the limitations of existing studies.

Summary: This study explored musical and neuro-cognitive deficits in patients with mild-moderate major depressive disorder (MDD). The results showed that these patients had significant deficits in working memory, verbal learning, and memory, but no differences in music cognition. The study also found a significant relationship between music cognition and attention.

Summary: This study investigated the dimensionality of cognitive processes related to memory capacity and language ability in typically developing children and children with developmental language disorder. The results showed that cognitive abilities accounted for a significant amount of the variance in linguistic abilities, and the relationship between working memory and language ability was significantly stronger in the typically developing group than in the language disorder group.

Summary: This study found that although cuttlefish may show changes in certain cognitive abilities with age, episodic-like memory function appears to be preserved in cuttlefish, suggesting that memory deterioration is delayed in this species.

Summary: The study found a negative association between affective symptoms and cognition from middle to late adulthood, with affective symptoms predicting poorer verbal memory and processing speed over a period of 16 years, but cognition not predicting subsequent affective symptoms.

Summary: Imaging the human brain over the past 35 years has the potential to enhance education. Educators of all types need to understand how to realize this potential in practical terms. This paper reviews the current understanding of brain networks underlying elementary education and its preparation for later learning. This knowledge can improve assessment devices, child behavior, motivation and lead to immediate and lasting improvements in educational systems.

Summary: This study aimed to explore the association between metabolic syndrome and cognitive function in middle-aged individuals. The results showed that metabolic syndrome was associated with lower performance in attention and memory, possibly due to elevated fasting glucose and abdominal obesity. This study highlights the importance of addressing cognitive decline and dementia risk in middle-aged individuals.

Summary: The study developed regression-based norms for the FAS phonemic fluency test and found that years of education was the only significant predictor of test performance. The proposed norms provided a more accurate adjustment for demographics in the Norwegian population compared to American norms.

Summary: This study explored the factors associated with subjective age, finding that it may result from the interaction between factors that increase or decrease age-related thoughts and mental processes. The results show that individuals reporting an older subjective age are more likely to experience significant negative changes and engage in negative age-related thoughts. Women experience a more negative subjective age and more age-related events than men.

Summary: This study aimed to investigate the safety and effectiveness of anthocyanins, a nutritional compound, in maintaining cognitive functioning in older people. The 24-week trial on 206 participants with mild cognitive impairment or cardiometabolic disorders showed that anthocyanin supplementation was safe and well-tolerated. Although there was no significant group difference in episodic memory at the end of the study, there were significant differences in slopes during weeks 8-24, with improvement in the anthocyanin group and deterioration in the placebo group.

Summary: This study aimed to develop 2-year cognitive change norms for adults aged 41-84 and evaluated these norms in groups with AD biomarkers. The results showed that the group with cognitive complaints exhibited a trend of cognitive decline, with the A+T/N+ subgroup showing the most significant decline.

Summary: Cognitive differences in memory, information processing speed, and executive functions are common in autistic and high autistic trait populations. Older adults with high autistic traits experience more difficulties in memory, IPS, and EF tasks compared to those with low autistic traits. Further research is needed to examine age-related changes in cognitive profiles of older adults with autism traits.

Summary: Lower awareness of age-related gains and higher awareness of age-related losses are risk factors for depressive and anxiety symptoms. The study found that higher AARC-losses predicted more depressive and anxiety symptoms, and these associations were stronger in individuals who frequently ruminate. Age did not moderate the associations between AARC-gains/losses and depressive/anxiety symptoms.

Summary: This epidemiological study aimed to explore the temporal relationship between depressive symptoms and cognitive function. The results demonstrated a bidirectional association between the two, with cognitive function initially having a slightly stronger impact on depressive symptoms, and depressive symptoms having a stronger impact on cognitive function during follow-up. However, within-person effects showed a dominant influence of depressive symptoms on cognitive function.

Summary: This study estimated the numbers of diagnosed and undiagnosed autistic individuals in England and examined the differences in diagnostic rates based on socio-demographic factors. The results showed a higher prevalence of diagnosed autism in children/young people compared to adults/older adults. Age-related inequalities were also evident in new diagnoses, indicating the urgent need to improve access to adult autism diagnostic services.

Summary: This study investigated the presence of (poly)phenol and methylxanthine metabolites in plasma and cerebrospinal fluid from individuals at risk of dementia and predicted their transport mechanism across the blood-brain barrier using in silico modeling. The results suggest that (poly)phenols and methylxanthines can cross the blood-brain barrier via passive diffusion or transport carriers to exert neuroprotective effects.
