Although there are modifiable risk factors, the public remains largely unaware of dementia prevention. Many individuals turn to online platforms such as YouTube for health-related information, where content can shape beliefs, attitudes, and decision-making. However, little is known about how people interpret and discuss dementia prevention in these digital spaces. This study aimed to explore how dementia prevention is perceived by the public, as reflected in user generated comments posted on YouTube videos related to dementia prevention. A qualitative thematic analysis was conducted by examining comments from YouTube videos identified through Google Advanced Search. Twenty-six videos were selected based on predefined criteria, and comments were extracted and cleaned prior to analysis. Engagement metrics, including views, likes, and replies, were also examined to understand how users interacted with the content. Data were analyzed using Braun and Clarke's six-step thematic approach. A total of 7314 comments were retrieved from 26 videos. Following data cleaning and removal of ineligible comments, 2034 comments were included for final analysis. Thematic analysis revealed three themes: (i) fear and perceived vulnerability to dementia; (ii) perceptions of dementia risk factors; and (iii) trust and credibility of dementia prevention information. These themes revealed fear, modifiable vs non-modifiable risk factors, and both public reliance on and distrust of scientific evidence. YouTube provides an important platform for public discussion about dementia prevention. Although it offers opportunities to increase awareness, viewer comments reflected inconsistent understandings and conflicting beliefs about dementia prevention, highlighting the need for clear, evidence-based communication to improve public understanding.</p>","PeriodicalId":72778,"journal":{"name":"Dementia (London, England)","volume":" ","pages":"14713012261498324"},"PeriodicalIF":2.2,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149186680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Members of the Arabic and Vietnamese groups faced language barriers and cultural stigma, which increased a sense of exclusion and isolation. In response, they emphasised the need for accessible transport, inclusive social groups, and community-wide dementia education to create a more dementia-friendly environment.

Despite this, they are less likely to seek help from services. Previous research has investigated barriers to help-seeking for dementia in ethnic minorities, but this research has typically involved samples drawn from a range of ethnic groups. Given their increased risk, it would be useful to focus specifically on the African Caribbean community. Fourteen African Caribbean participants, with experience of supporting a family member with memory loss, participated in an interview exploring their perceptions of barriers to help-seeking. Reflexive Thematic Analysis was used to guide the collection and analysis of interview data. Historical experiences of the African Caribbean community have made them self-reliant and stoical in the face of adversity, and unwilling to seek help, particularly from a society that rejected them. Memory loss is likely to be attributed to old age or harmless individual traits, and the concept of dementia is not well rooted in the culture. Shame and stigma attached to mental difficulties in the culture also make people unwilling to seek help and motivated to mask their difficulties. There are cultural and familial expectations that care should be provided by daughters within the family, not by outsiders. Participants were reluctant to make use of services due to concerns that, because of racism, the family member will receive a poorer quality service, a culturally insensitive service, or be mistreated. There is a need to raise awareness and understanding of dementia in this community, and to tackle the stigma associated with it. Ongoing racism and cultural insensitivity within services also need to be addressed. Because of the community's mistrust of government and mainstream institutions, African Caribbean community organisations should be funded to lead efforts to deal with these issues.</p>","PeriodicalId":72778,"journal":{"name":"Dementia (London, England)","volume":" ","pages":"1597-1611"},"PeriodicalIF":2.2,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13569902/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145056284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, end-of-life quality indicators such as place of death provide limited information about the totality of the dying process. Hence, this study's aim was to identify factors affecting the relatively understudied concept of final place of care (where care was received in the last three days of life i.e. home/inpatient hospice/hospital) and its concordance with previously stated preferences (goal-concordance). A retrospective cohort study was conducted using secondary data (electronic medical records) from 284 individuals enrolled in a home-based palliative care service for people with advanced dementia in Singapore. Despite demonstrating positive impacts, the service was unable to meet some individuals' end-of-life preferences. Analysis used multivariate binomial logistic regression, concordance and sensitivity analyses. Results found home to be the most common final place of care (81.7%). Better biological and functional status, and inconsistent preferences for place of care and death predicted hospital admission for care (9.2%). Discomfort, oral feeding, psychosocial challenges, and family unemployment predicted inpatient hospice admissions (9.2%); these were often late and unplanned, suggesting a preference for home until death was imminent. Better prognosis, infection two weeks before death/admission, higher caregiver burden and psychosocial challenges predicted non-concordance with preferences (14.4%). The results highlight the unpredictable, protracted trajectory of people with advanced dementia and the multifaceted challenges of end-of-life care and death. Unlike place of death, relatively stable factors (sociodemographic, chronic comorbidities) had no effect on final place of care. These fresh insights, supported by findings about end-of-life transitions in international literature, have implications for policies and practices to advance the global health goal of facilitating people with advanced dementia not just to die but to spend their final days at their place of choice.</p>","PeriodicalId":72778,"journal":{"name":"Dementia (London, England)","volume":" ","pages":"1568-1596"},"PeriodicalIF":2.2,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13569898/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145008623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
