Abstract
Background Population-based research on the prevalence and determinants of dementia, Alzheimer's disease, and cognitive impairment is scarce in East Africa. Objective To provide an overview of community- and population-based studies among older adults on the prevalence of dementia and cognitive impairment in East Africa, and identify research gaps. Methods We carried out a literature search using three electronic databases (PubMed, Scopus, Google Scholar) using pertinent search terms. Results After screening 445 publications, we identified four publications on the population-based prevalence of dementia, and three on cognitive impairment. Prevalence rates varied from 6- 23% for dementia, and 7- 44% for cognitive impairment, among participants aged≥50-70 years. Old age and a lower education level were risk factors for dementia and cognitive impairment. Physical inactivity, lack of a ventilated kitchen, and history of central nervous system infections and chronic headache were associated with increased odds of dementia. Female sex, depression, having no spouse, increased lifetime alcohol consumption, low income, rural residence, and low family support were associated with increased odds of cognitive impairment. Potential misclassification and non-standardized data collection methods are research gaps that should be addressed in future studies. Conclusions Establishing collaborative networks and partnering with international research institutions may enhance the capacity for conducting population-based studies on dementia and cognitive impairment in East Africa. Longitudinal studies may provide valuable insights on incidence, as well as potential risk and protective factors of dementia and cognitive impairment, and may inform the development of targeted interventions including preventive strategies in the region.

Abstract
Background. The diagnosis of young-onset dementia presents significant challenges both for the person and their families, which often differ from the challenges faced with late-onset dementia. Evidence of the experience of service users and carers tends to reveal a negative appraisal of the care received, citing longer diagnosis times, poor clinician knowledge and lack of age-appropriate care. However, evidence looking into staff experiences of supporting someone with young-onset dementia is relatively scarce. The aim of this study was to explore the experiences and reflections of health and social care staff who support people with young-onset dementia within older adult mental health services, and whether their knowledge of the systems they work in could reveal the existence of barriers or facilitators to young-onset dementia care. Methods. Health and social care professionals working with people and carers with young-onset dementia across England were remotely interviewed between September and December 2021. Data were analysed using inductive thematic analysis. Findings. Sixteen staff members were interviewed. Three themes were constructed with six sub-themes. The first theme related to the perception of greater complexity around young-onset dementia support. The second theme describes staff fears around their ability to effectively support people with young-onset dementia, including the perception that young-onset dementia requires specialist input. The final theme describes systemic and structural inefficiencies which provide additional challenges for staff. Conclusions. Providing effective support for people with young-onset dementia and their families requires adjustments both within the clinician role and mental health services. Staff considered young-onset dementia support to be a specialist intervention and felt the services they work for are suited to generic mental health and dementia provision. Findings are discussed with recommendations relating to developing a standardised model of dementia care for young-onset dementia which recognises and responds to the unique experiences of young-onset dementia.

Giebel C, Hanna K, Tetlow H, Gabbay M, Cannon J. Co-producing a board game to learn and engage about dementia inequalities: First impacts on knowledge in the general population. Health Expect 2024; 27:e13977. [PMID: 39102705 DOI: 10.1111/hex.13977] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Revised: 01/03/2024] [Accepted: 01/07/2024] [Indexed: 08/07/2024] Open
Abstract
BACKGROUND Receiving and accessing care after a diagnosis of dementia, both for the person and their carer, are fraught with inequalities. The aim of this public engagement activity was to co-produce a board game about dementia inequalities to facilitate learning, dialogue and educate about different barriers, and facilitators, to diagnosis and care and to test the game's impact on dementia knowledge with the general public. METHODS Two virtual and two face-to-face workshops with people with dementia, unpaid carers, health and social care professionals and Third Sector representatives were held between October 2022 and June 2023. Virtual workshops involved discussions of inequalities and how a board game may feature inequalities. The first face-to-face workshop was split into the same activities, aided by outcomes from workshops 1 and 2. Workshop 4 attendees tested the prototype. The impact of the game on knowledge about dementia and inequalities was tested at a game play workshop in October 2023. RESULTS Forty stakeholders attended four workshops. Workshops provided step-by-step thoughts on how the game could be designed or modified. The final game, prototype tested in workshop 4, consists of a one-sided, two-half board depicting the prediagnosis process (left half) and postdiagnosis process (right half). Fifty-two members of the general public participated in the game play workshop, which led to significant improvements in knowledge about dementia (p < .001) and inequalities (p < .001). DISCUSSION The game can be used to improve knowledge about dementia inequalities for health and social care professionals, carers, people living with dementia, decision makers and the general public. PATIENT OR PUBLIC CONTRIBUTION This engagement activity fully involved people with dementia, unpaid carers, health and social care professionals and Third Sector representatives throughout, with two unpaid carers as public advisers on the team.

Which factors preceding dementia identification impact future healthcare use trajectories: multilevel analyses in administrative data. BMC Geriatr 2024; 24:89. [PMID: 38263052 PMCID: PMC10807194 DOI: 10.1186/s12877-023-04643-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Accepted: 12/27/2023] [Indexed: 01/25/2024] Open
Abstract
BACKGROUND Healthcare use patterns preceding a diagnosis of Alzheimer's Disease and Related Diseases (ADRD) may be associated with the quality of healthcare use trajectories (HUTs) after diagnosis. We aimed to identify determinants of future favorable HUTs, notably healthcare use preceding ADRD identification. METHODS This nationwide retrospective observational study was conducted on subjects with incident ADRD identified in 2012 in the French health insurance database. We studied the 12-month healthcare use ranging between 18 and 6 months preceding ADRD identification. The five-year HUTs after ADRD identification were qualified by experts as favorable or not. In order to take into account geographical differences in healthcare supply, we performed mixed random effects multilevel multivariable logistic regression model to identify determinants of future favorable HUTs. Analyses were stratified by age group (65-74, 75-84, ≥ 85). RESULTS Being a woman, and preventive and specialist care preceding ADRD identification increased the probability of future favorable HUT, whereas institutionalization, comorbidities, medical transportation and no reimbursed drug during [-18;-6] months decreased it. Besides, some specificities appeared according to age groups. Among the 65-74 years subjects, anxiolytic dispensing preceding ADRD identification decreased the probability of future favorable HUT. In the 75-84 years group, unplanned hospitalization and emergency room visit preceding ADRD identification decreased this probability. Among subjects aged 85 and older, short hospitalization preceding ADRD identification increased the probability of future favorable HUTs. CONCLUSION Regular healthcare use with preventive and specialist care preceding ADRD identification increased the probability of future favorable HUTs whereas dependency decreased it.
