Understanding how older adults perceive their aging can be an effective way to develop strategies to prevent vulnerability and promote healthy aging.Objective: The aim of this study was to investigate the self-perception of aging and its associated factors in a group of older adults in Morocco to contribute to healthy aging.Methods: This was a cross-sectional study conducted between June 2022 and July 2023 among 496 people aged 60 years and over who visited health centers in the province of Essaouira. A positive or negative self-perception of aging was established using the Attitudes Toward Own Aging subscale, which includes five items from the Philadelphia Geriatric Center Morale Scale. Sociodemographic characteristics and data related to lifestyle and health status were collected through interviews, by consulting health records, and were supplemented with anthropometric measurements. Binary logistic regression was used to determine the potential factors influencing self-perception of aging.Results: A negative self-perception of aging was identified in 21.4% of participants. Multivariate analysis revealed that being unmarried (OR 2.027; 95%CI 1.261-3.259), having depressive symptoms (OR 1.729; 95%CI 1.082-2.765), and being dependent (OR 1.926; 95%CI 1.134-3.272) were the main factors statistically associated with a negative self-perception of aging.Conclusion: A strategy to prevent loneliness and social isolation, as well as screening programs for depression and dependency in older adults, could contribute to successful and healthy aging.","PeriodicalId":39167,"journal":{"name":"Dementia e Neuropsychologia","volume":"20 ","pages":"e20250316"},"PeriodicalIF":0.0,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13102450/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147784261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of a valid and reliable instrument to identify apathy among PLHIV could allow early diagnosis and proper management of this condition.Objective: The aim of this paper was to translate, cross-culturally adapt, and validate the caregiver-rated Dimensional Apathy Scale (DAS) in PLHIV in Brazil.Methods: We followed five steps: translation, back translation, cultural adaptation, pretest, and test-retest. A pretest (n=20) and test-retest (n=80) were conducted with PLHIV from an HIV Referral Center in Brazil between August 2022 and March 2023. We determined the content validity index (CVI), Cronbach's alpha, and the intraclass correlation coefficient (ICC). To assess convergent and discriminant validity, apathy scores were correlated with cognitive function, as assessed by the International HIV Dementia Scale (IHDS), and depressive symptoms, as assessed by the Patient Health Questionnaire (PHQ-9).Results: Participants were predominantly male (82.5%), with a mean age of 41.7 (±13.4) years and a mean duration of infection of 8.1 (±1.9) years. The mean CVI of the Brazilian DAS version (DAS-Br) was 0.97. The translated version showed acceptable internal consistency (Cronbach's alpha: 0.727 (95%CI 0.632-0.806)) and good test-retest reliability (ICC 0.888 (95%CI 0.823-0.929). There was a moderate correlation between DAS-Br scores and depressive symptoms (r=0.425, p<0.01) and a nonsignificant correlation with cognition (r=0.167; p>0.05).Conclusion: The translation and cross-cultural adaptation of the DAS into Brazilian Portuguese resulted in a valid and reliable instrument for assessing apathy in PLHIV.","PeriodicalId":39167,"journal":{"name":"Dementia e Neuropsychologia","volume":"20 ","pages":"e20250343"},"PeriodicalIF":0.0,"publicationDate":"2026-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13008347/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147515395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Also, both bvFTD and AD patients exhibit executive dysfunction, but the extent to which such dysfunction contributes to memory impairments remains unclear.Objective: The aim of this study was to investigate interactions between executive functions and episodic memory in AD and bvFTD by manipulating executive control in a spatial source memory task.Methods: Twenty bvFTD patients, 18 AD patients, and 20 healthy controls completed a source memory test in which they should remember whether objects were previously seen on the left or right side of a computer screen. Critically, arrow cues (66.7% valid, 33.3% invalid) indicated the likely prior location of each object during retrieval.Results: bvFTD and AD patients showed overall similar memory performances but were impaired compared to controls. While cueing affected memory performances of controls and bvFTD patients, AD patients showed undistinguishable performances after valid and invalid cueing.Conclusion: These findings support the notion that episodic memory deficits in bvFTD can be as severe as in AD and demonstrate that, unlike bvFTD patients, patients with AD show difficulties in using information conveyed by cues during memory judgments, probably because of underlying attentional deficits.","PeriodicalId":39167,"journal":{"name":"Dementia e Neuropsychologia","volume":"20 ","pages":"e20250413"},"PeriodicalIF":0.0,"publicationDate":"2026-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13008346/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147515403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
