Which language is more affected in bilinguals with Alzheimer’s disease? Diagnostic sensitivity of the Multilingual Naming Test.
Conclusions: Testing primarily or exclusively in the dominant language is best for detecting AD naming impairments in bilinguals. However, AD affects the ability to access names in both languages, possibly for different reasons, and simple descriptions of language decline as “parallel” or “asymmetrical” (i.e., AD affecting one language more than the other) may be misleading in terms of the theoretical implications for bilingual language processing.

Multidomain modifiable dementia risk factors are associated with poorer cognition in midlife.
Conclusions: These findings may suggest that multidomain MDRFs are highly frequent in middle-aged adults and are related to poorer cognition. This supports that modifiable dementia risk is multidimensional and raises the possibility that multidomain behavioral intervention trials in middle-aged adults may be useful to delay or prevent cognitive impairment or decline.

Computerized cognitive interventions for adults with ADHD: A systematic review and meta-analysis.
Conclusions: We analyzed the risk of bias in the chosen studies and discuss the findings in terms of effect size. It is concluded that CCT has a small positive effect in adults with ADHD. Due to the lack of heterogeneity in intervention designs across the included studies, increased heterogeneity in future studies could help inform clinicians about the aspects of CCT, such as training type and length, that are most beneficial for this group.

Verbal problem-solving in agenesis of the corpus callosum: Analysis using semantic similarity.
Conclusion: These findings indicated that individuals with AgCC who have intelligence in the normal range are less able at the WCT taking all trials into account, although they often solve the problem eventually. This outcome is consistent with previous research indicating that callosal absence in AgCC results in a restricted imagination for possibilities, limiting their problem-solving and inferential capacities. The results also highlight the usefulness of semantic similarity as a means of scoring the WCT. (PsycInfo Database Record (c) 2023 APA, all rights reserved) (Source: Neuropsychology)

Design and validation of the 1-week memory battery for assessing episodic memory and accelerated long-term forgetting in cognitively unimpaired subjects.
Conclusion: Our findings indicate that the 1WMB has good psychometric properties, and future studies are needed to explore its potential usefulness to assess cognitively unimpaired subjects at increased risk of developing AD.

Revisiting the hypothesis of language retrogenesis from an evolutionary perspective.
Conclusions: Language acquisition in children and language degradation/loss in healthy ageing follow the principle of retrogenesis, but mostly in domains that are cognitively demanding and that depend on recently evolved brain devices. Putting this differently, the components of language that emerged more recently appear to be more, and earlier, affected during ageing, as well as developed later over childhood.

Error monitoring in amnestic mild cognitive impairment: Cognitive correlates and relationship to measures of everyday function.
Conclusions: Compared to HOAs, individuals with aMCI exhibited poorer conscious error awareness. Better error monitoring was associated with higher working memory and executive functioning abilities and predicted better everyday functioning. If individuals with aMCI experience difficulties recognizing performance inaccuracies, they will be unable to correct their errors, leading to mistakes in everyday task completion and difficulty implementing appropriate compensatory strategies. Findings suggest that error monitoring may be a potential target for intervention with individuals with aMCI. (PsycInfo Database Record (c) 202...

Daily activity diversity and daily working memory in community-dwelling older adults.
Conclusions: Our results on within-person concurrent and time-lagged associations between daily activity diversity and daily working memory strengthen the existing evidence on the beneficial effect of activity diversity on older adults’ cognitive performance. Results are discussed in the context of cognitive reserve theory. (PsycInfo Database Record (c) 2023 APA, all rights reserved) (Source: Neuropsychology)

Predictors of cognitive dysfunction one-year post COVID-19.
Neuropsychology, Vol 37(5), Jul 2023, 557-567; doi:10.1037/neu0000876Objectives: (a) To characterize the frequency of objective cognitive deficits and self-perceived cognitive difficulties and (b) to explore demographic and clinical predictors of cognitive dysfunction and cognitive complaints. Method: One hundred and ten adults diagnosed with COVID-19 between March and November 2020, aged ≤ 74 years underwent a brief neuropsychological evaluation 12 months after infection, which included: Brief Visuospatial Memory Test–Revised, California Verbal Learning Test, and Symbol Digit Modalities Test.

Further evaluation of narrative description as a measure of cognitive function in Alzheimer’s disease.
Conclusions: While many linguistic features were associated with cognitive status, and some were able to detect early cognitive impairment or predictive of future cognitive decline, all the features we tested seem to have been captured by the ND score. Thus, adding linguistic measures to the ND test score did not add to its value in assessing current or predicting future cognitive status.

A review of novel Cognitive Challenge Tests for the assessment of preclinical Alzheimer’s disease.
Conclusions: To meet the critical needs of a rapidly evolving field, cognitive assessment instruments must show sufficient scientific rigor including robust sensitivity, specificity, and predictive utility among culturally and linguistically diverse populations and importantly, be correlated to AD biomarkers.

Extended FNAME performance is preserved in subjective cognitive decline but highly affected in amnestic mild cognitive impairment.
Conclusions: The worse performance of aMCI in the extended FNAME implies an impairment in associative memory abilities beyond recall. The similar performance of CON and SCD might be explained by the recruitment of SCD participants that did not spontaneously seek help for memory decline.

Superior verbal learning and memory in pediatric brain tumor survivors treated with proton versus photon radiotherapy.
Conclusion: Results suggest that PRT is associated with verbal memory sparing, driven by effective encoding and use of learning strategies. Future work may help to clarify underlying neural mechanisms associated with verbal memory decline, which will better inform treatment approaches.
