The Behavioral Risk Factor Surveillance System (BRFSS) is a randomized national U.S. telephone survey administered by state health departments. This study aimed to identify how Black/African Americans understand BRFSS caregiver and cognitive decline surveys and terminology to inform health messaging that centers the Black/African American experience. In focus groups, BRFSS surveys were administered to Black/African Americans (n = 30) aged ≥ 45 in Oregon. Participants were asked how they interpreted BRFSS terms 'memory loss' and 'confusion,' how these terms related to Alzheimer's and dementia, and about caregiving and cognitive decline experiences. The culturally responsive Africana Worldview guided interpretation, which centers the Black/African American experience and individuals within interdependent relationships and community identity when explaining behaviors of people from the African diaspora. BRFSS survey responses differed from focus group responses to the same questions. Two participants reported providing care in the past two years on the survey; in discussions, 21 participants reported providing care in the past two years. Interpretations of BRFSS terminology varied greatly. Differences between age-related cognitive changes, dementia and Alzheimer's disease were unclear. Cognitive decline was largely understood in terms of identity loss and relationship changes with the affected individual, and how that individual's relationship changed within community. Caution is advised when using BRFSS data to frame messaging because key cognitive health terms are not universally understood. Messaging that apply the Africana Worldview centralizes relationships and community rather than impact on individual's day-to-day activities, may be more effective for Black/African Americans and for other groups with different cultural and life experiences.

Importance: Although 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) is a well-established cross-sectional biomarker of brain metabolism in dementia with Lewy bodies (DLB), the longitudinal change in FDG-PET has not been characterized.
Objective: To investigate longitudinal FDG-PET in prodromal DLB and DLB, including a subsample with autopsy data, and report estimated sample sizes for a hypothetical clinical trial in DLB.
Design, Setting, And Participants: Longitudinal case-control study with mean (SD) follow-up of 3.

Background And Objectives: This systematic review aims to synthesize the current literature on the association between chemotherapy (CTX) and chemotherapy-related cognitive impairment (CRCI) with functional and structural brain alterations in patients with noncentral nervous system cancers.
Methods: A comprehensive search of the PubMed/MEDLINE, Web of Science, and Embase databases was conducted, and results were reported following preferred reporting items for systematic review and meta-analyses guidelines. Data on study design, comparison cohort characteristics, patient demographics, cancer type, CTX agents, neuroimaging methods, structural and functional connectivity (FC) changes, and cognitive/psychological assessments in adult patients were extracted and reported.

Background And Objectives: Rolandic epilepsy (RE), the most common childhood focal epilepsy syndrome, is characterized by a transient period of sleep-activated epileptiform activity in the centrotemporal regions and variable cognitive deficits. Sleep spindles are prominent thalamocortical brain oscillations during sleep that have been mechanistically linked to sleep-dependent memory consolidation in animal models and healthy controls. Sleep spindles are decreased in RE and related sleep-activated epileptic encephalopathies.

Objectives: Caring for an individual with cognitive impairment carries a physical, mental, and emotional toll. This manuscript examines the relationship between caregiver psychosocial measures and longitudinal cognitive outcomes of stroke survivors, as well as analyzing the psychosocial factors as moderators of stroke severity and cognition.
Methods: This analysis was conducted on caregiver and stroke survivor dyads (n = 157) that participated in the Caring for Adults Recovering from the Effects of Stroke (CARES) project, an ancillary study of the REasons for Geographic and Racial Differences in Stroke (REGARDS) national cohort study.

Purpose Of Review: To highlight recent findings on the prevalence and risk and protective factors for dementia in Indigenous Peoples, who are disproportionately affected by health inequities driven by social determinants of health and historical injustices. With increasing numbers of Indigenous individuals entering older age, there is a growing need for research to better understand dementia and opportunities for prevention in Indigenous Peoples.
Recent Findings: Recent studies highlight a wide range of dementia prevalence across Indigenous Peoples, with estimates varying significantly by methodology, socio-cultural context, and region with stark gaps in regional representation.
