Objectives: To evaluate older adult emergency department (ED) patients for depression and cognitive impairment and to re-evaluate those findings 2 weeks later.
Design: Prospective cohort study.
Setting: ED.
Participants: One thousand two hundred six older community-dwelling ED patients consented to participate; 811 (67%) completed the 2-week follow-up.
Measurements: Screening for depression (9-item Patient Health Questionnaire) and cognitive impairment (Six-Item Screener) was performed. Changes were evaluated through paired comparisons.
Results: At 2-week follow-up, for depression, 27 of 97 (28%) with baseline positive tests remained positive, and 22 of 706 (3%) with baseline negative tests were positive. At 2-week follow-up, for cognitive impairment, five of 43 (12%) with baseline positive tests remained positive, and 11 of 765 (1%) with baseline negative tests were positive.
Conclusion: Significant variability exists for depression and cognitive impairment testing completed during and after the ED visit, with markedly fewer subjects testing positive at follow-up. The variability may reflect changes in clinical state, confounding from other conditions, or poor validity of the instruments in the ED setting. Further studies are needed to explain these findings before case-finding for these conditions is implemented in the ED setting.

Montreal Cognitive Assessment Hearing Impairment (MoCA-H): cross-cultural adaptation to Brazilian Portuguese.
Codas
January 2025
Departamento de Fonoaudiologia, Universidade Federal de Santa Maria - UFSM - Santa Maria (RS), Brasil.
Purpose: This study aimed to adapt the Montreal Cognitive Assessment Hearing Impaired (MoCA-H) into Brazilian Portuguese (BP).
Methods: This was a descriptive, cross-sectional, quantitative, and qualitative study involving participants selected by convenience. The instrument was adapted from its original version, in a six-stage process consisting of the following: Stage 1 - Translation and back translation of the MoCA-H; Stage 2 - Stimulus analysis and selection; Stage 3 - Semantic analysis of stimuli; Stage 4 - Analysis by non-expert judges, part 1; Stage 5 - Analysis by non-expert judges, part 2; Stage 6 - Pilot study.
Constructs across a hierarchical, dimensional model of psychopathology show differential associations with social and general cognitive ability.
PLoS One

Many psychiatric disorders and associated psychopathology dimensions are related to social cognitive deficits and reduced general cognitive ability. The current study applied a hierarchical, dimensional approach to better understand associations among psychopathology, social cognition, and general cognitive ability. Data were collected from two samples (n = 653), including psychosis-spectrum patients, their first-degree relatives, and individuals from community sources.

Alzheimer Center Limburg, Department of Psychiatry and Neuropsychology, School for Mental Health and Neuroscience, Maastricht University, Maastricht, the Netherlands.
Importance: Baseline cerebral microbleeds (CMBs) and APOE ε4 allele copy number are important risk factors for amyloid-related imaging abnormalities in patients with Alzheimer disease (AD) receiving therapies to lower amyloid-β plaque levels.
Objective: To provide prevalence estimates of any, no more than 4, or fewer than 2 CMBs in association with amyloid status, APOE ε4 copy number, and age.
Design, Setting, And Participants: This cross-sectional study used data included in the Amyloid Biomarker Study data pooling initiative (January 1, 2012, to the present [data collection is ongoing]).
Depressive Symptoms and Amyloid Pathology.
JAMA Psychiatry
January 2025
Department of Psychiatry and Neurochemistry, Institute of Neuroscience and Physiology, Sahlgrenska Academy at the University of Gothenburg, Mölndal, Sweden.
Importance: Depressive symptoms are associated with cognitive decline in older individuals. Uncertainty about underlying mechanisms hampers diagnostic and therapeutic efforts. This large-scale study aimed to elucidate the association between depressive symptoms and amyloid pathology.

While Category Fluency (CF) is widely used to help profile semantic memory, item-level scoring (ILS) approaches to this test have been proposed to obtain indices that are less influenced by non-semantic supportive functions. We systematically reviewed the literature to test the hypotheses that (1) compared with healthy adults, individuals with a clinical diagnosis suggestive of neurodegeneration generate words of lower semantic complexity; (2) compared with young adults, older adults generate words of higher semantic complexity. We searched six databases (date of search: 8 December 2023) for studies that relied on CF and ILS methods, in normal ageing and in age-associated neurodegeneration.
