AI Article Synopsis
- The Autobiographical Memory Test (AMT) is a key tool for measuring overgeneral autobiographical memory (OGM), but its effectiveness in Spanish and older populations had not been examined prior to this study.
- The research involved administering a Spanish version of AMT to young (520 participants) and older adults (155 participants) and included various analyses like confirmatory factor analysis (CFA) and differential item functioning (DIF).
- Findings revealed that while the AMT has a consistent one-factor structure, three items showed age-related differences in functioning, suggesting these items should be removed when comparing memory performance across different age groups.
Article Abstract
The Autobiographical Memory Test (AMT) is the most widely used measure of overgeneral autobiographical memory (OGM). The AMT appears to have good psychometric properties, but more research is needed on the influence and applicability of individual cue words in different languages and populations. To date, no studies have evaluated its usefulness as a measure of OMG in Spanish or older populations. This work aims to analyze the applicability of the AMT in young and older Spanish samples. We administered a Spanish version of the AMT to samples of young (N = 520) and older adults (N = 155). We conducted confirmatory factor analysis (CFA), item response theory-based analysis (IRT) and differential item functioning (DIF). Results confirm the one-factor structure for the AMT. IRT analysis suggests that both groups find the AMT easy given that they generally perform well, and that it is more precise in individuals who score low on memory specificity. DIF analysis finds three items differ in their functioning depending on age group. This differential functioning of these items affects the overall AMT scores and, thus, they should be excluded from the AMT in studies comparing young and older samples. We discuss the possible implications of the samples and cue words used.

Background: Population aging and the increase in memory-related diseases have motivated the search for accessible cognitive screening instruments. To develop a digital memory and learning test (DMLT) based on Rey's Auditory Verbal Learning Test (RAVLT) principles to assess cognition in the elderly and identify early cognitive decline.
Methods: The research was divided into two phases: developing the digital test and the experimental phase of comparison with a reference test.

Koopman operator theory has found significant success in learning models of complex, real-world dynamical systems, enabling prediction and control. The greater interpretability and lower computational costs of these models, compared to traditional machine learning methodologies, make Koopman learning an especially appealing approach. Despite this, little work has been performed on endowing Koopman learning with the ability to leverage its own failures.

Background: MicroRNAs have been linked to dementia. However, understanding their relation to cognition in the general population is required to determine their potential use for the detection and prevention of age-associated cognitive decline and preclinical dementia. Therefore, we examined the association of circulating microRNAs with cognitive performance in a population-based cohort and the possible underlying mechanisms.

Background: The recent approval of two anti-amyloid antibodies, Aducanamab and Lecanamab, have set the stage for the next generation of anti-amyloid treatments. Despite the capability of these treatments to lower Aβ brain levels, there is thus far limited clinical efficacy on cognitive outcomes. Because eligibility for treatment includes individuals with MCI or mild dementia, that often harbor mixed pathologies, the cognitive impact of other brain pathologies may be important.

Background: Alzheimer's disease (AD) is sometimes characterized as "type 3 diabetes" because hyperglycemia impairs cognitive function, particularly in the medial temporal lobe (MTL) and prefrontal regions. Further, both AD and type 2 diabetes (T2D) disproportionately impact African Americans. Although people with T2D are generally suggested to have lower episodic memory and executive function, limited data exist in older African Americans.
