Objectives: The increasing number of older adults with dementia is a large and growing public health problem. Alzheimer's disease, the prevailing form of dementia, is projected to quadruple worldwide. To date, the care and social integration of individuals with dementia is complicated by limited collaborations between biomedicine and other disciplines. The objective of this paper is therefore to reflect on the orientation of biomedicine with regard to the science of dementia, and to articulate a path for moving forward.
Methods: The authors drew upon, and expanded, the insights of an interdisciplinary, international workshop entitled 'Bioethics and the Science of Aging: The Case of Dementia' held in October 2012 at the University of California in Berkeley.
Results: The care of individuals with dementia compels solid interdisciplinary collaborations. There are several issues affecting the care of individuals with dementia: (1) an evolving definition of dementia; (2) the ambiguous benefits of the diagnosis of dementia; (3) ethical conflicts concerning consent processes and clinical trials; and (4) a limited understanding of the perspective of the person with dementia.
Conclusion: We argue that it is time for a renewed dialogue between biomedicine and other disciplines -- particularly public health, the social sciences, the medical humanities and bioethics. This interdisciplinary dialogue would facilitate a process of self-reflection within biomedicine. This dialogue will also provide the foundation for equitable public health interventions and will further prioritize the values and preferences of individuals with dementia, as well as their care and social integration.

Neuropsychological tests and machine learning: identifying predictors of MCI and dementia progression.
Aging Clin Exp Res
March 2025
Data Science for Health, Fondazione Bruno Kessler, Via Sommarive 18, Trento, 38123, Italy.
Background: Early prediction of progression in dementia is of major importance for providing patients with adequate clinical care, with considerable impact on the organization of the whole healthcare system.
Aims: The main task is tailoring robust and consolidated machine learning models to detect which neuropsychological tests are more effective in predicting a patient's mental status. In a translational medicine perspective, such identification tool should find its place in the clinician's toolbox as a support throughout his daily diagnostic routine.
Association of Diet and Waist-to-Hip Ratio With Brain Connectivity and Memory in Aging.
JAMA Netw Open
March 2025
Department of Psychiatry, University of Oxford, Oxford, United Kingdom.
Importance: Epidemiological studies suggest that lifestyle factors are associated with risk of dementia. However, few studies have examined the association of diet and waist to hip ratio (WHR) with hippocampus connectivity and cognitive health.
Objective: To ascertain how longitudinal changes in diet quality and WHR during midlife are associated with hippocampal connectivity and cognitive function in later life.
Use of Safety Net Enclosures as an Additional Treatment of Neuropsychiatric Symptoms in Dementia: A Prospective Cohort Study.
Alzheimer Dis Assoc Disord
March 2025
Parnassia Psychiatric Institute, Den Haag, The Netherlands.
Objective: Safety net enclosures are used in addition to (non-) pharmacological interventions in patients suffering from neuropsychiatric symptoms in dementia. However, no data on effectiveness are available.
Methods: In a prospective observational cohort study of 81 patients diagnosed with dementia, and admitted to a geriatric ward of a psychiatric hospital, available behavioral assessment scores were used to compare 45 patients who used safety net enclosures with 36 patients who never used safety net enclosures.
This study aimed to explore the applicability of a dementia prevention lifestyle change program based on the Health Belief Model in the community. A total of 9 participants were included in this study. The participants completed a 10-session program using the KEEP strategy.

This ageist and ableist stereotype that older people are asexual or post-sexual negatively affects nurses and other healthcare professionals, as they are regularly faced with residents' sexual expressions. How are nurses to view and respond appropriately if a clear understanding of current ethical concepts and argumentations about intimacy and sexuality in older adults is lacking? This study aimed to document and better understand current ethical concepts and arguments about intimacy and sexuality in institutionalised older adults.
