Advancements in dementia research, diagnostics, and care in Latin America: Highlights from the 2023 Alzheimer's Association International conference satellite symposium in Mexico City.

INTRODUCTION: While Latin America (LatAm) is facing an increasing burden of dementia due to the rapid aging of the population, it remains underrepresented in dementia research, diagnostics, and care. METHODS: In 2023, the Alzheimer's Association hosted its eighth satellite symposium in Mexico, highlighting emerging dementia research, priorities, and challenges within LatAm. RESULTS: Significant initiatives in the region, including intracountry support, showcased their efforts in fostering national and international collaborations; genetic studies unveiled the unique genetic admixture in LatAm; researchers conducting emerging clinical trials discussed ongoing culturally specific interventions; and the urgent need to harmonize practices and studies, improve diagnosis and care, and use affordable biomarkers in the region was highlighted. DISCUSSION: The myriad of topics discussed at the 2023 AAIC satellite symposium highlighted the growing research efforts in LatAm, providing valuable insights into dementia biology, genetics, epidemiology, treatment, and care.

Latin American Initiative for Lifestyle Intervention to Prevent Cognitive Decline (LatAm-FINGERS): Study design and harmonization.

INTRODUCTION: Latin American Initiative for Lifestyle Intervention to Prevent Cognitive Decline (LatAm-FINGERS) is the first non-pharmacological multicenter randomized clinical trial (RCT) to prevent cognitive impairment in Latin America (LA). Our aim is to present the study design and discuss the strategies used for multicultural harmonization. METHODS: This 1-year RCT (working on a 1-year extension) investigates the feasibility of a multi-domain lifestyle intervention in LA and the efficacy of the intervention, primarily on cognitive function. An external harmonization process was carried out to follow the FINGER model, and an internal harmonization was performed to ensure this study was feasible and comparable across the 12 participating LA countries. RESULTS: Currently, 1549 participants have been screened, and 815 randomized. Participants are ethnically diverse (56% are Nestizo) and have high cardiovascular risk (39% have metabolic syndrome). DISCUSSION: LatAm-FINGERS overcame a significant challenge to combine the region's diversity into a multi-domain risk reduction intervention feasible across LA while preserving the original FINGER design.

To live and age as who we really are: Perspectives from older LGBT+ people in Ireland.

This Open Letter discusses the theme of 'diversity in brain health' in research, practice and policy for older LGBT+ people. It is written by a multidisciplinary group of Atlantic Fellows for Equity in Brain Health at the Global Brain Health Institute in Trinity College Dublin (TCD), from a variety of disciplines (health economics, human geography, anthropology, psychology, gerontology) and professions (researcher, clinicians, writers, practicing artists). The group developed a workshop to explore the theme of 'Diversity and Brain Health' through the lens of lesbian, gay, bisexual, transgender/transsexual plus (LGBT+).  . Guided by two advisors (Prof Agnes Higgins, TCD; Mr Ciaran McKinney, Age and Opportunity), we invited older LGBT+ people and those interested in the topic of LGBT+ and ageing, healthcare providers, policy makers and interested members of the research community. We partnered with colleagues in the School of Law to include socio-legal perspectives. Following the workshop, Roe and Walrath wrote an opinion editorial, published in the Irish Times during the 2019 PRIDE festival, and were subsequently invited by HRB Open Research to provide a more detailed expansion of that work. In this Open Letter we describe the theme of 'diversity and brain health' and some of the lessons we learned from listening to the lived experience of older LGBT+ people in Ireland today. We illustrate why it's important to understand the lived experience of older LGBT+ people and highlight the failure of the State to evaluate the experience of LGBT+ people in policy implementation. We call on researchers, clinicians, service planners and policy makers, to recognize and address diversity as an important way to address health inequities in Ireland.

New horizons in frailty: the contingent, the existential and the clinical.

In the past decade, frailty research has focused on refinement of biomedical tools and operationalisations, potentially introducing a reductionist approach. This article suggests that a new horizon in frailty lies in a more holistic approach to health and illness in old age. This would build on approaches that view healthy ageing in terms of functionality, in the sense of intrinsic capacity in interplay with social environment, whilst also emphasising positive attributes. Within this framework, frailty is conceptualised as originating as much in the social as in the biological domain; as co-existing with positive attributes and resilience, and as situated on a continuum with health and illness. Relatedly, social science-based studies involving interviews with, and observations of, frail, older people indicate that the social and biographical context in which frailty arises might be more impactful on the subsequent frailty trajectory than the health crisis which precipitates it. For these reasons, the article suggests that interpretive methodologies, derived from the social sciences and humanities, will be of particular use to the geriatrician in understanding health, illness and frailty from the perspective of the older person. These may be included in a toolkit with the purpose of identifying how biological and social factors jointly underpin the fluctuations of frailty and in designing interventions accordingly. Such an approach will bring clinical approaches closer to the views and experiences of older people who live with frailty, as well as to the holistic traditions of geriatric medicine itself.
