Abstract
Racial disparities in adverse health outcomes with aging have been well described. Yet, much of the research focuses on racial comparisons, with relatively less attention to the identification of underlying mechanisms. To address these gaps, the Research Centers Collaborative Network held a workshop on aging, race, and health disparities to identify research priorities and inform the investigation, implementation, and dissemination of strategies to mitigate disparities in healthy aging. This article provides a summary of the key recommendations and highlights the need for research that builds a strong evidence base with both clinical and policy implications. Successful execution of these recommendations will require a concerted effort to increase participation of underrepresented groups in research through community engagement and partnerships. In addition, resources to support and promote the training and development of health disparities researchers will be critical in making health equity a shared responsibility for all major stakeholders.

Abstract
PURPOSE Post-mortem brain donation affords the opportunity to characterise disease by exploring global neuropathological changes. Such opportunities are essential to progress knowledge of CNS tumours such as Glioblastoma. A comprehensive understanding of the experience of consenting to brain donation is crucial to maximising consent rates while providing patient-centred care. This review aimed to synthesise the reported facilitators and barriers according to potential donors, next-of-kin (NOK) and clinician respondents. DESIGN Database searches included Embase, Medline, PsycINFO, Psychology and Behavioural Science and Scopus. Search terms focused on motivations, attitudes and psychosocial experiences of brain donation. Exclusions included organ transplantation and brain death. All studies were assessed for quality and validity using tools from the Joanna Briggs Institute. To determine perceptions of benefit and harm, a method guided by the thematic analysis of Braun and Clarke was employed to reflexively assess and identify common themes and experiences. RESULTS 40 studies (15 qualitative, 25 quantitative) were included involving participants with paediatric cancer, neurodegenerative and psychological diseases. Perceptions of benefit included benefit to future generations, aiding scientific research, avoidance of waste, improved treatments and the belief that donation will bring consolation or aid in the grieving process. Perceptions of harm included a perceived conflict with religious beliefs, disfigurement to the donor, emotional distress at the time of autopsy and discord or objections within the family. CONCLUSION Brain donation can afford a sense of purpose, meaning and empowerment for donors and their loved ones. Careful strategies are required to mitigate or reduce potential harms during the consent process.

Abstract
BACKGROUND African Americans (AAs) are underrepresented in health-related research studies. Few studies have investigated how behaviors of study recruiters affect recruitment of older AAs versus non-Latinx Whites (NLWs). OBJECTIVES The aim of this study was to explore whether caring behaviors influence AA and NLW older adults' decision to participate in hypothetical, high-commitment, health-related research studies and differences in participants' enrollment decisions by race. METHODS Using a descriptive, cross-sectional study design, guided by Kristen Swanson's middle-range theory of caring, a research-savvy sample of 60 AA and 60 NLW adults (age > 65 years) were randomly assigned one of two written vignettes. The concept of caring behaviors was manipulated and illustrated in a hypothetical recruitment scenario. A participant feedback survey was used to assess (a) participants' perceptions of caring and uncaring behaviors exhibited by the fictitious research recruiter, (b) differences in their willingness to participate based on vignette type, and (c) participants' judgment of the research recruiter as being caring or uncaring. A chi-square test assessed the association among categorical variables (caring behavior and participants' race). RESULTS Participants who received the vignette with the high caring recruiter were more than twice as likely to agree to participate in the study than those who received the vignette with the low caring recruiter. AA and NLW participants did not differ in their likelihood to agree to participate. Participants who received the caring vignette and judged the recruiter as caring were 5 times as likely to agree to participate in the high-commitment study than those who received the uncaring vignette ( p < .001). Associations did not vary by race. DISCUSSION This experimental study of equally recruited older adults from an existing longitudinal study revealed that caring behaviors in recruitment strategies are associated with an increased likelihood of participation in high-commitment research with older adults. The research-savvy AA participants were just as likely to participate in the hypothetical high-commitment research as their NLW peers when the fictional research recruiter was perceived as having caring behaviors. When targeting specific populations, it is essential to employ nuanced recruitment approaches where the study recruiters are attuned to caring behaviors.

Abstract
BACKGROUND Biological biomarkers yielded from positron emission tomography (PET) brain scans serve as a pathway to understanding Alzheimer's disease pathology. PET brain scan data remain limited for populations traditionally under-included in aging research. OBJECTIVE The purpose of this qualitative study was to examine participant-identified barriers to PET brain scan consent and characterize participant-informed elements of educational materials needed to facilitate PET brain scan participation among older Black and Latino adults. METHODS Participants (N = 31) were older adults (mean age = 71 years) who self-identified as either non-Latino Black (n = 15) or Latino (n = 16). Each participant took part in a one-time, in-depth individual interview. Researchers analyzed data guided by a Grounded Theory Approach with both Open Coding and Constant Comparative Coding. RESULTS Four overarching themes emerged across all participants: 1) knowledge limitations; 2) requirements for consent; 3) motivators for participation; and 4) social networks. Within the four themes, there were differences based on participant ethnoracial group. For example, for Theme Three, older Black adults indicated that they would expect compensation for PET brain scan participation. Conversely, older Latinos stated that they would appreciate, but not anticipate, a financial incentive. All participants stressed the importance of written educational materials with subsequent verbal discussions with studystaff. CONCLUSION Findings inform the development and implementation of scientifically-relevant and culturally-cognizant engagement approaches, educational materials, and recruitment strategies to increase PET brain scan participation by diverse older adults.

Abstract
Objective Research directly examining brain tissue has played an important role in understanding the pathology and pathogenesis of multiple sclerosis (MS) and other diseases of the central nervous system. Such research relies heavily on donations of post-mortem brain tissue yet little is known about the attitudes of people with multiple sclerosis (MS) about brain donation. We aimed to assess the attitudes of people with MS toward brain donation, their preferences related to discussions of brain donation, and factors associated with attitudes toward brain donation including sociodemographic and clinical characteristics, health literacy and religiosity. Methods In a cross-sectional study, we surveyed participants in the North American Research Committee on Multiple Sclerosis (NARCOMS) Registry regarding their attitudes toward brain donation, reasons for participating or not participating in brain donation, and related communication preferences. We used multivariable logistic regression analyses to test factors associated with attitudes regarding brain donation. Results Most of the 4,520 participants were women (80.8%), self-identified as white (88.1%), with a post-secondary education, functional health literacy and moderate-severe disability. Sixty-two percent of participants would consider brain donation. Factors associated with considering brain donation included female gender, having a post-secondary education, being physically active, having moderate-severe disability and more comorbidities, and alcohol intake. Seventy-five percent of participants indicated that they preferred to receive information regarding brain donations from physicians. Conclusion Two-thirds of people with MS would consider brain donation. People with MS desire to hear about brain donation from their health care providers rather than other sources.

Abstract
Research on racial differences in Alzheimer disease (AD) dementia has increased in recent years. Older African American individuals bear a disproportionate burden of AD and cognitive impairment compared with non-Latino white individuals. Tremendous progress has been made over the past two decades in our understanding of the neurobiological substrates of AD. However, owing to well-documented challenges of study participant recruitment and a persistent lack of biological data in the African American population, knowledge of the drivers of these racial disparities has lagged behind. Therapeutic targets and effective interventions for AD are increasingly sought, but without a better understanding of the disease in African American individuals, any identified treatments and/or cures will evade this rapidly growing at-risk population. In this Perspective, I introduce three key obstacles to progress in understanding racial differences in AD: uncertainty about diagnostic criteria, disparate cross-sectional and longitudinal findings; and a dearth of neuropathological data. I also highlight evidence-informed strategies to move the field forward. In this Perspective, Barnes introduces three key obstacles to progress in our understanding of racial differences in Alzheimer disease and highlights evidence-informed strategies that can move the field forward.

Abstract
Background A small number of older adults in the United States who agree to brain donation for clinical research belong to diverse racial, ethnic, and economic groups. Those who agree, however, are less likely to have completed brain autopsies compared with older non-Latino Whites of higher socioeconomic status. As such, our understanding of Alzheimer's disease and related dementias remains limited in these underrepresented and understudied populations. Here, we examine perceived impediments to completed brain autopsies among diverse older adults who have agreed to brain donation for clinical research. Methods Participants (N=22) were older adults (mean age=77 years) who self-identified as African American (n=8), Latino (n=6), or White of lower income (n=8). All participants had previously agreed to brain donation via the Uniform Anatomical Gift Act. Each participant took part in a one-time, semi-structured focus group. Data were analyzed using a Grounded Theory Approach with both Open Coding and Constant Comparative Coding. Results Perceived impediments to completed brain autopsies varied by group. Older African Americans and older Latinos expressed concern about a lack of follow-through by family members regarding their brain donation wishes. Older Whites of lower income indicated that their own uncertainty surrounding the processes of brain donation and brain autopsy might serve as an impediment. Discussion Diverse older adults expressed different perceived impediments to having brain autopsies completed upon their death. Continuous education for diverse older adults and their family members regarding brain donation for clinical research, including clear guidelines and processes, may facilitate completed brain autopsies among diverse older adults.
