The impacts of social determinants of health and cardiometabolic factors on cognitive and functional aging in Colombian underserved populations.

Global initiatives call for further understanding of the impact of inequity on aging across underserved populations. Previous research in low- and middle-income countries (LMICs) presents limitations in assessing combined sources of inequity and outcomes (i.e., cognition and functionality). In this study, we assessed how social determinants of health (SDH), cardiometabolic factors (CMFs), and other medical/social factors predict cognition and functionality in an aging Colombian population. We ran a cross-sectional study that combined theory- (structural equation models) and data-driven (machine learning) approaches in a population-based study (N = 23,694; M = 69.8 years) to assess the best predictors of cognition and functionality. We found that a combination of SDH and CMF accurately predicted cognition and functionality, although SDH was the stronger predictor. Cognition was predicted with the highest accuracy by SDH, followed by demographics, CMF, and other factors. A combination of SDH, age, CMF, and additional physical/psychological factors were the best predictors of functional status. Results highlight the role of inequity in predicting brain health and advancing solutions to reduce the cognitive and functional decline in LMICs.

Genetic, Social, and Lifestyle Drivers of Healthy Aging and Longevity.

Purpose of Review: "Healthy aging" is the state of the aging process in which a person can maintain physical, social, mental, and spiritual wellness. This literature review presents an overview of recent studies that explore how biological, social, and environmental factors contribute to healthy aging. Recent Findings: A number of genome-wide association studies have been conducted recently for traits related to healthy aging, such as frailty index, healthspan, muscle strength, and parental longevity, leading to the discovery of dozens of genetic variants associated with these traits. In parallel, associations between healthy aging measures and multiple non-biological environmental elements have been identified as key moderators of the aging process, indirectly influencing day-to-day homeostatic processes. Summary: Individual variations in lifespan and healthspan are influenced by genetic factors, with a heritability of ~ 25% in developed countries. Non-genetic risk variance is explained in part by social, cultural, and lifestyle conditions. Altogether, these factors contribute to a multifaceted state of wellness over time, shaping individual risk to frailty and resilience during the aging process. Notably, "Blue Zone" populations, which are characterized by an abundance in healthy lifestyles across generations, share some commonalities regarding determinants of health.

Dementia caregiving across Latin America and the Caribbean and brain health diplomacy.

The prevalence of dementia in Latin America and the Caribbean is growing rapidly, increasing the burden placed on caregivers. Exacerbated by fragile health-care systems, unstable economies, and extensive inequalities, caregiver burden in this region is among the highest in the world. We reviewed the major challenges to caregiving in Latin America and the Caribbean, and we propose regional and coordinated actions to drive future change. Current challenges include the scarcity of formal long-term care, socioeconomic and social determinants of health disparities, gender-biased burdens, growing dementia prevalence, and the effect of the current COVID-19 pandemic on families affected by dementia. Firstly, we propose local and regional short-term strategic recommendations, including systematic identification of specific caregiver needs, testing of evidence-based local interventions, contextual adaptation of strategies to different settings and cultures, countering gender bias, strengthening community support, provision of basic technology, and better use of available information and communications technology. Additionally, we propose brain health diplomacy (ie, global actions aimed to overcome the systemic challenges to brain health by bridging disciplines and sectors) and convergence science as frameworks for long-term coordinated responses, integrating tools, knowledge, and strategies to expand access to digital technology and develop collaborative models of care. Addressing the vast inequalities in dementia caregiving across Latin America and the Caribbean requires innovative, evidence-based solutions coordinated with the strengthening of public policies.

Caregiving for Patients With Frontotemporal Dementia in Latin America.

Latin America is a vast heterogeneous territory where chronic diseases such as mild cognitive impairment or dementia are becoming higher. Frontotemporal dementia (FTD) prevalence in this region is estimated to be around 12-18 cases per thousand persons. However, this prevalence is underestimated given the lack of awareness of FTD even among healthcare professionals. Family members are responsible for the care of patients with FTD at home. These caregivers deliver care despite being ill-equipped and living in the context of austerity policies and social inequities. They often face unsurmountable financial and social burdens that are specific to the region. The most important step to support caregivers in Latin America is to increase awareness of the disease at all levels. Healthcare diplomacy is fundamental to create joint efforts that push policies forward to protect caregivers of FTD patients.

Cannabidiol in the management of bruxism in behavioral variant of frontotemporal degeneration.

Awake bruxism is an understudied feature of behavioral variant of frontotemporal dementia (bvFTD). We present the case of aman who presented with psychiatric, behavioral, cognitive changes, and teeth clenching that resulted in significant changes in his teeth alignment including an underbite. He received multiple treatments with partial response. He then started using acannabidiol (CBD) capsule, and the grinding was almost completely relieved after this intervention. There is still no standardized pharmacology treatment for bruxism in patients with bvFTD. As aconsequence, acase-by-case approach is suggested. CBD can be helpful as an adjunct therapeutic agent for awake bruxism.Not StartedCompletedRejected.

The Multi-Partner Consortium to Expand Dementia Research in Latin America (ReDLat): Driving Multicentric Research and Implementation Science.

Dementia is becoming increasingly prevalent in Latin America, contrasting with stable or declining rates in North America and Europe. This scenario places unprecedented clinical, social, and economic burden upon patients, families, and health systems. The challenges prove particularly pressing for conditions with highly specific diagnostic and management demands, such as frontotemporal dementia. Here we introduce a research and networking initiative designed to tackle these ensuing hurdles, the Multi-partner consortium to expand dementia research in Latin America (ReDLat). First, we present ReDLat's regional research framework, aimed at identifying the unique genetic, social, and economic factors driving the presentation of frontotemporal dementia and Alzheimer's disease in Latin America relative to the US. We describe ongoing ReDLat studies in various fields and ongoing research extensions. Then, we introduce actions coordinated by ReDLat and the Latin America and Caribbean Consortium on Dementia (LAC-CD) to develop culturally appropriate diagnostic tools, regional visibility and capacity building, diplomatic coordination in local priority areas, and a knowledge-to-action framework toward a regional action plan. Together, these research and networking initiatives will help to establish strong cross-national bonds, support the implementation of regional dementia plans, enhance health systems' infrastructure, and increase translational research collaborations across the continent.

Subjective cognitive decline and elder mistreatment in Mexican community-dwelling older adults.

BACKGROUND AND OBJECTIVES: Elder mistreatment in individuals with subjective cognitive decline is an understudied public health problem that violates human rights. DESIGN AND METHODS: Cross-sectional study of 386 Mexican community-dwelling older adults. Individuals with episodic memory, executive function, language, visuospatial skills or attention cognitive complaints without low cognitive performance scores in the Mini-Mental State Examination and the Isaacs Set Test that were considered positive for subjective cognitive decline (SCD). Elder mistreatment (EM) was considered positive if any of the questions on the Geriatric Mistreatment Scale were answered affirmatively. Logistic regression models were created to test the association between SCD and EM. RESULTS: After adjustments made by age, sex, education and depressive symptoms a positive association was found between SCD and EM (OR = 2.226; 95%CI = 1.296 to 3.822 ; p = 0.004). This association was observed in all subtypes of cognitive complaints except excecutive function: episodic memory (OR = 2.219 ; 95%CI = 1.321 to 3.728 ; p = 0.003), language (OR = 2.500 ; 95% CI = 1.422 to 4.396 ; p = 0.001), visuospatial (OR = 2.158 ; 95%CI = 1.162 to 4.007 ; p = 0.015), attention (OR = 2.197 ; 95%CI = 1.206 to 4.001 ; p = 0.010) and executive (OR = 1 2.062 ; 95%CI = 0.981 to 4.333 ; p = 0.056). Discussion and Implications: This study brings to light the relation between SCD and EM in a population where it has been understudied. Exploring mistreatment in older adults who experience subjective cognitive decline might help preserve their safety and create future prevention and intervention strategies.

The impact of SARS-CoV-2 in dementia across Latin America: A call for an urgent regional plan and coordinated response.

The SARS-CoV-2 global pandemic will disproportionately impact countries with weak economies and vulnerable populations including people with dementia. Latin American and Caribbean countries (LACs) are burdened with unstable economic development, fragile health systems, massive economic disparities, and a high prevalence of dementia. Here, we underscore the selective impact of SARS-CoV-2 on dementia among LACs, the specific strain on health systems devoted to dementia, and the subsequent effect of increasing inequalities among those with dementia in the region. Implementation of best practices for mitigation and containment faces particularly steep challenges in LACs. Based upon our consideration of these issues, we urgently call for a coordinated action plan, including the development of inexpensive mass testing and multilevel regional coordination for dementia care and related actions. Brain health diplomacy should lead to a shared and escalated response across the region, coordinating leadership, and triangulation between governments and international multilateral networks.

Neurodegenerative Disease and the Experience of Homelessness.

Introduction: Today, half of the American homeless population is older than 50 years of age. This shift in age distribution among people experiencing homelessness has challenged our long-held views of the causes of homelessness. Age-related neurological diseases, especially neurodegenerative diseases of the brain (NDDB), may play a role eliciting homelessness in a significant proportion of vulnerable older adults. This article aims to explore relationships between homelessness and NDDB in a cohort of research participants enrolled in observational studies on NDDB at an academic center. Methods: We reviewed charts of the Memory and Aging Center (MAC) of the University of California, San Francisco's database searching for research participants with NDDB that had direct relationship to homelessness. We reviewed all research visits conducted between 2004 and 2018 (N = 5,300). Research participants who had any relationship to homelessness were included in this analysis. NDDB was diagnosed via comprehensive neurological, functional, neuropsychological, and biomarker assessments. Non-parametric tests were used for analysis. Thirteen participants were found to have a direct relationship with homelessness. Seven were female and the median of education was 16 (IR: 12.0-19.5) years. Participants were divided into two groups: Those who experienced homelessness while symptomatic from a NDDB but before formal diagnosis (n = 5, Group 1); and participants with formally diagnosed NDDB who exhibited a new propensity toward homelessness (n = 8, Group 2). Compared to Group 2, participants in Group 1 were younger (p = 0.021) and showed similar results in the neuropsychological evaluation. In both groups, the most prevalent diagnosis was frontotemporal dementia. In Group 1, the majority of participants became homeless in the setting of a fragile socioeconomic situation and informants believed that NDDB contributed or caused their homeless state. In Group 2, a new propensity toward homelessness became manifest in different ways and it stood out that all of these participants were well-supported by family and friends during their illness. Conclusions and Relevance: This case series highlights the role that NDDB may have in precipitating homelessness among vulnerable older adults, particularly in the setting of challenging socioeconomic circumstances and unsupportive living environments. Social ramifications of these findings, particularly pertaining to challenges around rehousing these individuals is discussed.

Factors Associated with Surrogate Self-Efficacy in Decision-Making for Patients with End-Stage Renal Disease.

AIM: The aim of the study is to assess which factors are associated with self-efficacy for making these decisions in surrogates of end-stage kidney disease patients. MATERIALS AND METHODS: Cross-sectional study conducted in the hemodialysis clinic of a private hospital in Mexico City. A total of 124 surrogates of patients in hemodialysis were included in the study. Self-efficacy for decision-making was assessed with the Family Decision-Making Self-Efficacy Scale. As factors related to decision-making self-efficacy, sociodemographic data, health information, and professional help received for dealing with end-of-life issues were assessed in both patients and surrogates. Functional status and advanced directives of the patient as well as prior experience in decision-making of the surrogates were also included. Logistic regression models were used to establish the associations. RESULTS: The mean age of participants was 49.4 years (standard deviation: 14). Factors associated to decision-making self-efficacy were awareness of the surrogate about the terminal disease of the patient (P < 0.001), prior conversation between the surrogate and the patient about end-of-life preferences (P = 0.037), time between the patient was told dialysis was required and accepting it inferior to 1 month (P = 0.016), and visual impairment of the patient (0.040). CONCLUSIONS: This study provides information of which factors are associated with self-effectiveness in surrogates of terminally ill renal patients so that strategies based on these considerations might be implemented in the future.
