Abstract
More than a fifth of people living with HIV in the US President's Emergency Plan for AIDS Relief-supported programmes are older individuals, defined as aged 50 years and older, yet optimal person-centred models of care for older adults with HIV in sub-Saharan Africa, including screening and treatment for geriatric syndromes and common comorbidities associated with ageing, remain undefined. This Position Paper explores the disproportionate burden of comorbidities and geriatric syndromes faced by older adults with HIV, with a special focus on women. We seek to motivate global interest in improving quality of life for older people with HIV by presenting available research and identifying research gaps for common geriatric syndromes, including frailty and cognitive decline, and multimorbidity among older people with HIV in sub-Saharan Africa. We share two successful models of holistic care for older people with HIV that are ongoing in Zimbabwe and Kenya. Lastly, we provide policy, research, and implementation considerations to best serve this growing population.

Abstract
Cognitive Stimulation Therapy (CST) is an evidence-based, non-pharmacological intervention for older adults with mild to moderate dementia. While CST has been adapted in various ways, this study explored the impact of adding a spiritual dimension to CST. Participants (N = 34) were divided into spiritual and traditional CST groups based on their residence. After a 14-session intervention involving interactive conversations, the spiritual CST group showed significantly lower depression scores (M = 2.7) compared to traditional CST (M = 6.5). With the global increase in dementia-related disorders, non-pharmacological interventions like CST offer crucial support for addressing memory loss. Social workers are uniquely positioned to deliver CST to diverse populations who value spirituality or faith in their daily lives.

Abstract
Cognitive stimulation therapy (CST) was found to significantly improve cognitive function and quality of life (QOL) in patients with mild-to-moderate dementia in the UK. However, indigenous research on older adults with dementia in Taiwan is scarce. Therefore, this study developed and investigated the effects of a Taiwan version of group CST (CST-T) through a quasi-experimental trial. Excluding the dropouts, there were 13 experimental participants (M = 78.9 ± 9.0) and 13 control participants (77.9 ± 5.6). The results indicated significant improvements in cognitive function, QOL, and daily life functioning in the experimental group compared with the control group, and these effects remained evident at a 3-month follow-up.

Abstract
BACKGROUND AND OBJECTIVES Many community dementia services such as home-visiting services and center-based activities were suspended during the coronavirus 2019 pandemic. This study investigated the efficacy of a caregiver-delivered cognitive stimulation therapy (CDCST) on people with dementia during the pandemic. RESEARCH DESIGN AND METHODS This was a 2-arm randomized controlled trial involving 241 patient-caregiver dyads assigned to a 15-week CDCST or control group (usual care). We hypothesized that CDCST would facilitate significant improvements among people with dementia (cognition, behavioral/psychiatric symptoms, and quality of life) and their caregivers (caregiving appraisal, attitudes, and psychological well-being) at postintervention (T1) and at the 12-week follow-up (T2). Generalized estimating equations evaluated the study outcomes. RESULTS A total of 230 dyads completed the study, with good program adherence (93%). Participants in the CDCST showed significant improvements in cognition (p < .001), behavioral and psychiatric symptoms (p =. 027), and quality of life (p =.001) at the 3-month follow-up period. Family caregivers had improved positive aspects of caregiving (p = .008; p = .049) and decreased negative attitudes toward people with dementia (p =. 013; p < .001) at both T1 and T2. There were nonsignificant changes in the caregivers' perceived burden, distress, and psychological well-being. DISCUSSION AND IMPLICATIONS Family caregivers could be trained to provide cognitive stimulation at home for people with dementia, which could benefit both parties. CDCST could manage to improve the cognition, neuropsychiatric symptoms, and quality of life of people with dementia, while also improving caregiving appraisal and negative attitudes among family caregivers. CLINICAL TRIAL REGISTRATION NUMBER NCT03803592.

Abstract
Background Dementia is a severe neurodegenerative disorder and it is a group of acquired symptoms associated with impaired cognitive functions. In low-income settings particularly in Sub-Saharan Africa (SSA), it is often seen as part of normal aging. Environmental, behavioral, and lifestyle interventions have the potential to alter the disease course of dementia. Objective This study is aimed to synthesize the literature/evidence(s) on the management practice and treatment outcomes of dementia in SSA. Method Comprehensive literature was searched in PubMed database, Cochrane Library, and Google Scholar. Eligibility has been set, and based on the criteria, initially, a total of 442 results were obtained, and from those around 183 articles were duplicated. After examining titles and abstracts of records 26 articles were identified. Finally, five randomized clinical trials (RCT) and three prospective cohort studies that were reported on the management practice and treatment outcome of dementia in SSA were eligible for analysis. RCT and prospective cohort studies were used to strengthen the quality of evidence. The quality of the included RCT studies was assessed by using the Cochrane Risk of Bias Tool. Result A total of 2781 patient data were included in the final analysis. Of these, 2354 patients were obtained from 5 RCTs and 427 patients from 3 prospective cohort studies, which were conducted in SSA countries. RCT studies were done on the feasibility and clinical effectiveness of cognitive stimulation therapy (CST) showed improvements in language memory domains and physical health. In addition, studies that focus on the management of human immunodeficiency virus-associated dementia (HIVAD) were reported to improve neurocognitively. Conclusion CST is applicable in low-resource settings and it shows improvements in cognitive function and quality of life. Early initiation of combination antiretroviral therapy in resource-limited settings has been associated with improvement in the cognitive function of HIVAD.

Abstract
INTRODUCTION There is a scarcity of epidemiological data on neurodegenerative diseases (NDs) in East Africa. This meta-analysis provides the regional prevalence of NDs, their contributing factors, and evidence of change over time concerning gender per age or year. METHODS Articles were retrieved from electronic databases following the PRISMA standard. RESULTS Forty-two studies were reviewed, and 25 were meta-analyzed with a random-effects model. The pool estimate proportion of 15.27%, 95% CI (0.09-0.23) (I2 = 98.25%), (Q = 1,369.15, p < 0.0001) among a population of 15,813 male/female and 1,257 with NDs. Epidemiological characteristics associated with NDs include Dyskinesias prevalence 55.4%, 95% CI (13.5; 90.9), I2 (96%) and subsistence farming prevalence 11.3%, 95% CI (5.8; 20.9), I2 (99%). Publication bias by Egger test was (z = 4.1913, p < 0.0001), while rank correlation test using Kendall's model was (tau = 0.1237, p = 0.3873). Heterogeneity (R2 design = 5.23%, p design < 0.0001; R2 size = 52.163%, p size < 0.001; and R2 period = 48.13, p period < 0.0001. Covariates (R2 design + size + period = 48.41%, p < 0.001). CONCLUSION There is a high prevalence of NDs in the East African region, which could impact life expectancy, morbidity, and quality of life. Thus, early screening and regular surveillance could assist in management strategies.

Abstract
OBJECTIVES Portugal is one of the most aged countries in the world and dementia is increasing among the Portuguese population. It is estimated to affect around 200,000 people in Portugal. There is a clear need for non-pharmacological interventions to ameliorate the symptoms of dementia and improve the quality of life. Cognitive Stimulation Therapy (CST), a worldwide well-known program developed in the United Kingdom (UK), is recognized as a cost-effective intervention, with benefits both in cognitive function and quality of life of people with mild to moderate dementia. We tested the feasibility and cultural appropriateness and adapted CST to Portuguese people with dementia. METHODS The Formative Method for Adapting Psychotherapy (FMAP) model for cultural adaptation was used. A focus group discussion with health professionals and caregivers provided the basis for cultural adaptation, as well as feedback from participants, caregivers, and facilitators after a pilot study. RESULTS Some modifications were required, especially related to linguistic issues, in 11 of the 14 CST sessions. The adapted program was found to be acceptable and enjoyable in a small sample of people with dementia in a rehabilitation context. CONCLUSIONS CST seems feasible and culturally appropriate in Portugal. A systematically developed and culturally adapted manual is ready to be used in a large-scale implementation and validation of CST in Portugal. CLINICAL IMPLICATIONS CST is a valid program for the Portuguese culture, contributes to the availability of a structured and effective clinical intervention for PwD in Portugal and to the possibility of comparing programs across countries.

Abstract
BACKGROUND Depression is a common psychological symptom associated with dementia. Pharmacological approaches are often used despite two large negative trials of efficacy. This meta-analysis examines nonpharmacological (i.e., psychosocial) approaches for symptoms of depression in people living with dementia and reports statistical and clinical significance. METHODS Relevant studies published between 2012 and 2020 were sourced by searching electronic databases: MEDLINE, EMBASE, PsychINFO, Social Work Abstracts and the Cochrane Central Register of Controlled Trials. Studies were assessed for methodological quality. Random-effects meta-analysis was performed to calculate a pooled effect size (ES) and 95% confidence intervals (CI). RESULTS Overall, 37 nonpharmacological studies were identified including 2,636 participants. The mean quality rating was high (12/14, SD=1.4). Meta-analysis revealed that nonpharmacological approaches were significantly associated with reduced symptoms of depression with a medium effect size (ES=-0.53, 95%CI [-0.72, -0.33], p < 0.0001). There was considerable heterogeneity between studies. Meta-regression revealed this was not driven by intervention type or setting (residential versus community). CONCLUSIONS Nonpharmacological approaches such as reminiscence, cognitive stimulation/ rehabilitation, therapeutic, music-based approaches and education/ training, have the potential to reduce symptoms of depression in dementia.

Effectiveness of Reminiscence Therapy versus Cognitive Stimulation Therapy in Older Adults with Cognitive Decline: A Quasi-Experimental Pilot Study. NURSING REPORTS 2022; 12:339-347.

Abstract
Cognitive impairment can represent a predecessor to neuro-degenerative processes; however, evidence suggests that non-pharmacologic interventions such as reminiscence therapy (RT) and cognitive stimulation therapy (CST) can potentially stabilize or reverse this trend. Community-based settings are widely regarded as the key area of intervention by healthcare professionals in this field. Thus, this study aimed to assess the effects of an RT and a CST program in the cognition, depressive symptomatology, and quality of life (QoL) of older adults with cognitive decline who attend community support structures (CSS) in central Portugal. A quasi-experimental study with two arms (RT and CST program) was conducted for seven weeks. Participants were allocated to each arm based on the CSS they attended. Of the 109 older adults initially screened, 76 completed the intervention (50 in the RT program and 26 in the CST program). A pre- and post-intervention analysis showed statistically significant differences in older adults’ cognition, especially in their delayed recall ability, in both groups. Older adults in the RT program evidence improved QoL scores post-intervention. Both the RT and CST programs implemented throughout the study are beneficial to older adults’ cognitive performance, although results are more pronounced in the earlier stages of cognitive decline. Participation in the RT program was associated with improvements in older adults’ QoL scores.

Abstract
In tandem with the ever-increasing aging population in low and middle-income countries, the burden of dementia is rising on the African continent. Dementia prevalence varies from 2.3% to 20.0% and incidence rates are 13.3 per 1000 person-years with increasing mortality in parts of rapidly transforming Africa. Differences in nutrition, cardiovascular factors, comorbidities, infections, mortality, and detection likely contribute to lower incidence. Alzheimer's disease, vascular dementia, and human immunodeficiency virus/acquired immunodeficiency syndrome-associated neurocognitive disorders are the most common dementia subtypes. Comprehensive longitudinal studies with robust methodology and regional coverage would provide more reliable information. The apolipoprotein E (APOE) ε4 allele is most studied but has shown differential effects within African ancestry compared to Caucasian. More candidate gene and genome-wide association studies are needed to relate to dementia phenotypes. Validated culture-sensitive cognitive tools not influenced by education and language differences are critically needed for implementation across multidisciplinary groupings such as the proposed African Dementia Consortium.

Performing One-Session Cognitive Stimulation to Interact with Patients with Dementia in a Hospital for Mood Improvement: A Retrospective Single-Arm Cohort Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19031431. [PMID: 35162465 PMCID: PMC8835672 DOI: 10.3390/ijerph19031431] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/11/2021] [Revised: 01/18/2022] [Accepted: 01/23/2022] [Indexed: 11/16/2022]
Abstract
Developing support and an environment for patients with dementia in hospitals is important. This study aims to assess the immediate effect of one-session cognitive stimulation intervention on the mood of patients with dementia in a hospital as preliminary evidence. This study included 33 female patients. The cognitive stimulation intervention was conducted in the day room of the hospital ward by two occupational therapists. The patients participated in one or more sessions. The cognitive stimulation intervention was designed to discuss current affairs that implicitly stimulate memory, executive function, and language skills, according to the cognitive stimulation definition. Outcomes were evaluated using a two-dimensional mood scale. The primary outcome was pleasure. The before and after session scores for the first session and the average score before and after each session at multiple times were compared. The patients' pleasure showed significant improvements in both analyses. These results may indicate that one-session Cognitive stimulation intervention in a hospital effectively improves a mood of pleasure immediately. This study is the first report to provide preliminary evidence on the beneficial alterations of mood after one-session cognitive stimulation intervention for patients with dementia in hospitals. Cognitive stimulation intervention may be an effective non-pharmacotherapy for these patients.

Abstract
Background Knowledge of and attitudes towards dementia vary across countries, and for caregivers in low- and middle-income countries (LMICs), access to information can be challenging. There is an urgent need for brief, easily accessible and culturally appropriate educational courses for caregivers of persons with dementia, providing much needed information whilst addressing important psychological concepts such as stigma. Methods An international and multidisciplinary team developed Dementia Awareness for Caregivers (DAC) courses in four stages: (1) scoping review and module agreement, (2) development of an International template (DAC-International) containing a standardised process for adding information, (3) development of local DACs using a standardised format and (4) acceptability of courses in Brazil, India and Tanzania. Findings The DAC-International was developed, comprising three modules: ‘What is dementia?’; ‘Positive engagement’ and ‘Caring for someone with dementia’. Three local versions were developed from this (DAC-Brazil, DAC-India and DAC-Tanzania), where additions of country-specific information included prevalent stereotypes and the addition of culturally relevant case studies. An initial field test was conducted in each country (n = 85), which indicated acceptability to participants. Conclusions The methods used here resulted in culturally valid and acceptable educational courses for carers of people with dementia. Future work will consist of large-scale, formal evaluations and the development of additional local courses.

Abstract
BACKGROUND The majority of people with dementia live in low-and middle-income countries (LMICs). In sub-Saharan Africa (SSA) human-resource shortages in mental health and geriatric medicine are well recognized. Use of technological solutions may improve access to diagnosis. We aimed to assess the diagnostic accuracy of a brief dementia screening mobile application (app) for non-specialist workers in rural Tanzania against blinded gold-standard diagnosis of DSM-5 dementia. The app includes 2 previously-validated culturally appropriate low-literacy screening tools for cognitive (IDEA cognitive screen) and functional impairment (abbreviated IDEA-IADL questionnaire). METHODS This was a 2-stage community-based door-to-door study. In Stage1, rural primary health workers approached all individuals aged ≥60 years for app-based dementia screening in 12 villages in Hai district, Kilimanjaro Tanzania.In Stage 2, a stratified sub-sample were clinically-assessed for dementia blind to app screening score. Assessment included clinical history, neurological and bedside cognitive assessment and collateral history. RESULTS 3011 (of 3122 eligible) older people consented to screening. Of these, 610 were evaluated in Stage 2. For the IDEA cognitive screen, the area under the receiver operating characteristic (AUROC) curve was 0.79 (95% CI 0.74-0.83) for DSM-5 dementia diagnosis (sensitivity 84.8%, specificity 58.4%). For those 358 (44%) completing the full app, AUROC was 0.78 for combined cognitive and informant-reported functional assessment. CONCLUSIONS The pilot dementia screening app had good sensitivity but lacked specificity for dementia when administered by non-specialist rural community workers. This technological approach may be a promising way forward in low-resource settings, specialist onward referral may be prioritized.

Abstract
BACKGROUND Community-based primary-level workers (PWs) are an important strategy for addressing gaps in mental health service delivery in low- and middle-income countries. OBJECTIVES: To evaluate the effectiveness of PW-led treatments for persons with mental health symptoms in LMICs, compared to usual care. SEARCH METHODS: MEDLINE, Embase, CENTRAL, ClinicalTrials.gov, ICTRP, reference lists (to 20 June 2019). SELECTION CRITERIA: Randomised trials of PW-led or collaborative-care interventions treating people with mental health symptoms or their carers in LMICs. PWs included: primary health professionals (PHPs), lay health workers (LHWs), community non-health professionals (CPs). DATA COLLECTION AND ANALYSIS: Seven conditions were identified apriori and analysed by disorder and PW examining recovery, prevalence, symptom change, quality-of-life (QOL), functioning, service use (SU), and adverse events (AEs). Risk ratios (RRs) were used for dichotomous outcomes; mean difference (MDs), standardised mean differences (SMDs), or mean change differences (MCDs) for continuous outcomes. For SMDs, 0.20 to 0.49 represented small, 0.50 to 0.79 moderate, and ≥0.80 large clinical effects. Analysis timepoints: T1 (<1 month), T2 (1-6 months), T3 ( >6 months) post-intervention. MAIN RESULTS: Description of studies 95 trials (72 new since 2013) from 30 LMICs (25 trials from 13 LICs). Risk of bias Most common: detection bias, attrition bias (efficacy), insufficient protection against contamination. Intervention effects *Unless indicated, comparisons were usual care at T2. "Probably", "may", or "uncertain" indicates "moderate", "low," or "very low" certainty evidence. Adults with common mental disorders (CMDs) LHW-led interventions a. may increase recovery (2 trials, 308 participants; RR 1.29, 95%CI 1.06 to 1.56); b. may reduce prevalence (2 trials, 479 participants; RR 0.42, 95%CI 0.18 to 0.96); c. may reduce symptoms (4 trials, 798 participants; SMD -0.59, 95%CI -1.01 to -0.16); d. may improve QOL (1 trial, 521 participants; SMD 0.51, 95%CI 0.34 to 0.69); e. may slightly reduce functional impairment (3 trials, 1399 participants; SMD -0.47, 95%CI -0.8 to -0.15); f. may reduce AEs (risk of suicide ideation/attempts); g. may have uncertain effects on SU. Collaborative-care a. may increase recovery (5 trials, 804 participants; RR 2.26, 95%CI 1.50 to 3.43); b. may reduce prevalence although the actual effect range indicates it may have little-or-no effect (2 trials, 2820 participants; RR 0.57, 95%CI 0.32 to 1.01); c. may slightly reduce symptoms (6 trials, 4419 participants; SMD -0.35, 95%CI -0.63 to -0.08); d. may slightly improve QOL (6 trials, 2199 participants; SMD 0.34, 95%CI 0.16 to 0.53); e. probably has little-to-no effect on functional impairment (5 trials, 4216 participants; SMD -0.13, 95%CI -0.28 to 0.03); f. may reduce SU (referral to MH specialists); g. may have uncertain effects on AEs (death). Women with perinatal depression (PND) LHW-led interventions a. may increase recovery (4 trials, 1243 participants; RR 1.29, 95%CI 1.08 to 1.54); b. probably slightly reduce symptoms (5 trials, 1989 participants; SMD -0.26, 95%CI -0.37 to -0.14); c. may slightly reduce functional impairment (4 trials, 1856 participants; SMD -0.23, 95%CI -0.41 to -0.04); d. may have little-to-no effect on AEs (death); e. may have uncertain effects on SU. Collaborative-care a. has uncertain effects on symptoms/QOL/SU/AEs. Adults with post-traumatic stress (PTS) or CMDs in humanitarian settings LHW-led interventions a. may slightly reduce depression symptoms (5 trials, 1986 participants; SMD -0.36, 95%CI -0.56 to -0.15); b. probably slightly improve QOL (4 trials, 1918 participants; SMD -0.27, 95%CI -0.39 to -0.15); c. may have uncertain effects on symptoms (PTS)/functioning/SU/AEs. PHP-led interventions a. may reduce PTS symptom prevalence (1 trial, 313 participants; RR 5.50, 95%CI 2.50 to 12.10) and depression prevalence (1 trial, 313 participants; RR 4.60, 95%CI 2.10 to 10.08); b. may have uncertain effects on symptoms/functioning/SU/AEs. Adults with harmful/hazardous alcohol or substance use LHW-led interventions a. may increase recovery from harmful/hazardous alcohol use although the actual effect range indicates it may have little-or-no effect (4 trials, 872 participants; RR 1.28, 95%CI 0.94 to 1.74); b. may have little-to-no effect on the prevalence of methamphetamine use (1 trial, 882 participants; RR 1.01, 95%CI 0.91 to 1.13) and functional impairment (2 trials, 498 participants; SMD -0.14, 95%CI -0.32 to 0.03); c. probably slightly reduce risk of harmful/hazardous alcohol use (3 trials, 667 participants; SMD -0.22, 95%CI -0.32 to -0.11); d. may have uncertain effects on SU/AEs. PHP/CP-led interventions a. probably have little-to-no effect on recovery from harmful/hazardous alcohol use (3 trials, 1075 participants; RR 0.93, 95%CI 0.77 to 1.12) or QOL (1 trial, 560 participants; MD 0.00, 95%CI -0.10 to 0.10); b. probably slightly reduce risk of harmful/hazardous alcohol and substance use (2 trials, 705 participants; SMD -0.20, 95%CI -0.35 to -0.05; moderate-certainty evidence); c. may have uncertain effects on prevalence (cannabis use)/SU/AEs. PW-led interventions for alcohol/substance dependence a. may have uncertain effects. Adults with severe mental disorders *Comparisons were specialist-led care at T1. LHW-led interventions a. may have little-to-no effect on caregiver burden (1 trial, 253 participants; MD -0.04, 95%CI -0.18 to 0.11); b. may have uncertain effects on symptoms/functioning/SU/AEs. PHP-led or collaborative-care a. may reduce functional impairment (7 trials, 874 participants; SMD -1.13, 95%CI -1.78 to -0.47); b. may have uncertain effects on recovery/relapse/symptoms/QOL/SU. Adults with dementia and carers PHP/LHW-led carer interventions a. may have little-to-no effect on the severity of behavioural symptoms in dementia patients (2 trials, 134 participants; SMD -0.26, 95%CI -0.60 to 0.08); b. may reduce carers' mental distress (2 trials, 134 participants; SMD -0.47, 95%CI -0.82 to -0.13); c. may have uncertain effects on QOL/functioning/SU/AEs. Children with PTS or CMDs LHW-led interventions a. may have little-to-no effect on PTS symptoms (3 trials, 1090 participants; MCD -1.34, 95%CI -2.83 to 0.14); b. probably have little-to-no effect on depression symptoms (3 trials, 1092 participants; MCD -0.61, 95%CI -1.23 to 0.02) or on functional impairment (3 trials, 1092 participants; MCD -0.81, 95%CI -1.48 to -0.13); c. may have little-or-no effect on AEs. CP-led interventions a. may have little-to-no effect on depression symptoms (2 trials, 602 participants; SMD -0.19, 95%CI -0.57 to 0.19) or on AEs; b. may have uncertain effects on recovery/symptoms(PTS)/functioning.

Abstract
BACKGROUND Cognitive Stimulation Therapy (CST) is considered a gold-standard, evidence-based and cost-effective approach to improve cognitive function and quality of life of people with mild to moderate dementia. AIMS To validate CST for the Portuguese population and test its effectiveness. METHODS A single-blind, multi-center, randomized controlled trial recruited 112 older people with dementia. The primary outcome measure was cognition and secondary measures were quality of life, communication, autonomy, anxiety, depression, and global functioning. We also explored whether CST benefits people differently according to context, gender and level of cognitive reserve. RESULTS Fifty-five people were randomized to the intervention and 57 to the control group. In the post-test, the intervention group significantly improved relative to controls in cognition (ADAS-Cog, p = 0.013), communication (HCS, p = 0.045), behaviour (CAPE-BRS, p = 0.017) and in global dementia rating (CDR, p = 0.008). Quality of life, depression and anxiety had no significant differences. The estimated number needed to treat was four for one to benefit a cognitive improvement (ADAS-Cog). CONCLUSIONS Group CST is valid for the Portuguese population with benefits for people with mild to moderate dementia.

Abstract
INTRODUCTION The effects of healthcare-related inequalities are most evident in low-resource settings. Such settings are often not explicitly defined, and umbrella terms which are easier to operationalise, such as 'low-to-middle-income countries' or 'developing countries', are often used. Without a deeper understanding of context, such proxies are pregnant with assumptions, insinuate homogeneity that is unsupported and hamper knowledge translation between settings. METHODS A systematic scoping review was undertaken to start unravelling the term 'low-resource setting'. PubMed, Africa-Wide, Web of Science and Scopus were searched (24 June 2019), dating back ≤5 years, using terms related to 'low-resource setting' and 'rehabilitation'. Rehabilitation was chosen as a methodological vehicle due to its holistic nature (eg, multidisciplinary, relevance across burden of disease, and throughout continuum of care) and expertise within the research team. Qualitative content analysis through an inductive approach was used. RESULTS A total of 410 codes were derived from 48 unique articles within the field of rehabilitation, grouped into 63 content categories, and identified nine major themes relating to the term 'low-resource setting'. Themes that emerged relate to (1) financial pressure, (2) suboptimal healthcare service delivery, (3) underdeveloped infrastructure, (4) paucity of knowledge, (5) research challenges and considerations, (6) restricted social resources, (7) geographical and environmental factors, (8) human resource limitations and (9) the influence of beliefs and practices. CONCLUSION The emerging themes may assist with (1) the groundwork needed to unravel 'low-resource settings' in health-related research, (2) moving away from assumptive umbrella terms like 'low-to-middle-income countries' or 'low/middle-income countries' and (3) promoting effective knowledge transfer between settings.

Psychometric properties of outcome measures in non-pharmacological interventions of persons with dementia in low-and middle-income countries: A systematic review. Psychogeriatrics 2021; 21:220-238. [PMID: 33336529 PMCID: PMC7986620 DOI: 10.1111/psyg.12647] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Revised: 11/07/2020] [Accepted: 11/26/2020] [Indexed: 02/06/2023]
Abstract
Despite high burden of dementia in low-and middle-income countries (LMICs), only a small number of clinical trials of psychosocial interventions for persons with dementia (PwD) have been conducted in these settings. It is essential that such trials use appropriate outcome measures that are methodologically robust and culturally appropriate to evaluate the effectiveness of interventions. We carried out a systematic review to examine the evidence base and psychometric properties of measures employed in these studies in LMICs. A systematic search of published literature on randomised controlled trials (RCT) of psychosocial interventions for PwD in LMICs between 2008 and April 2020 was carried out. Measures employed in each of the eligible studies were identified and through a focused search, we further explored the evidence base and psychometric properties employing Terwee criteria. Data extraction and quality appraisal were conducted by two independent reviewers. The review identified 41 measures from 17 RCTS which fulfilled eligibility criteria and they examined effectiveness across the domains of cognition (n = 16), behaviour and psychological symptoms (n = 11) and quality of life (n = 8). Of these 41, we were able to access relevant literature only for 18 and they were subject to psychometric analysis. Psychometric properties of these 18 instruments were at best modest, with Terwee scores ranging from 3 (low) to 15 (moderate). A majority of the studies were from China (n = 5) and Brazil (n = 6). The evidence base for the routinely employed measures in RCTs of non-pharmacological interventions for PwD in LMICs is limited. The quality of adaptation and validation of these instruments is variable and studies are largely uninformative about their psychometric properties and cultural appropriateness to the study setting. There is an urgent need to develop scientifically robust instruments in LMIC settings that can be confidently employed to measure outcomes in trials of psychosocial interventions for PwD.

Abstract
INTRODUCTION Despite wide uptake in high-income countries (HICs), less is known about the effectiveness and implementation of psychological, social and cognitive interventions in low- and middle-income countries (LMICs). Despite this, such interventions are increasingly used. The aim of this review was to appraise the effectiveness and implementation readiness of psychosocial interventions for people with dementia in LMICs. METHODS A systematic search of databases from 1998-2019. Studies were rated on two scales assessing quality and implementation readiness. RESULTS Seventeen articles describing 11 interventions in six countries were evaluated. Interventions included Cognitive Stimulation Therapy (CST), a Multidisciplinary Cognitive Rehabilitation Programme (MCRP), singing interventions, occupational therapy and reminiscence therapy. The quality of included studies was variable, and many had low sample sizes. Evidence for improving both cognition and quality of life was found in two interventions: Cognitive Stimulation Therapy (CST) and a Multidisciplinary Cognitive Rehabilitation Programme (MCRP). Implementation issues were more likely to be explored in studies of Cognitive Stimulation Therapy (CST) than in any other intervention. CONCLUSIONS Of the included studies here, CST appears to be the most implementation ready, improving both cognition and quality of life with implementation readiness effectively explored in two LMIC countries: India and Tanzania.

Abstract
OBJECTIVE The prevalence of dementia has been increasing particularly in developing countries but care provision is still limited in these regions. Psychosocial interventions are recognized as useful tools to improve cognitive and behavioral difficulties, as well as quality of life of people with dementia (PwD) and their caregivers. Cognitive stimulation therapy (CST) is an evidence-based psychosocial intervention, recommended and implemented in many countries. In Brazil, there is no validated psychosocial intervention for dementia care. The present study aims to explore feasibility and obtain preliminary data on the efficacy of CST-Brasil in a sample of 47 people with mild to moderate dementia attending an outpatient unit. METHODS A single-blind design was used, with participants being randomly allocated to either 14 sessions of CST + treatment as usual (TAU; n = 23) or TAU (n = 24) during 7 weeks. Changes in cognition, quality of life, depressive symptoms, caregiver burden and functionality were measured. RESULTS PwD receiving CST and their family caregivers expressed good acceptance of the intervention, with low attrition and high attendance. Participants receiving CST exhibited significant improvements in mood and in activities of daily living compared to TAU. There were no significant effects in cognition, quality of life and caregiver burden. CONCLUSIONS CST-Brasil proved to be a feasible and useful intervention to improve mood in PwD, with high acceptance between study participators. CST-Brasil is a promising psychosocial intervention for dementia and should be explored in other clinical settings to allow generalization to a wider Brazilian context.

Abstract
BACKGROUND Identifying older people who are most vulnerable to adverse outcomes is important. This is particularly so in low-resource settings, such as those in sub-Saharan Africa (SSA), where access to social and healthcare services is often limited. AIM To validate and further refine a frailty screening tool for SSA. METHODS Phase I screening of people aged 60 years and over was conducted using the Brief Frailty Instrument for Tanzania (B-FIT). In phase II, a stratified, frailty-weighed sample was assessed across a range of variables covering cognition, physical function (including continence, mobility, weakness and exhaustion) nutrition, mood, co-morbidity, sensory impairment, polypharmacy, social support and self-rated health. The frailty-weighted sample was also assessed for frailty according to the comprehensive geriatric assessment (CGA), which we used as our 'gold standard' diagnosis. RESULTS Of 235 people in the frailty-weighted sample, 91 (38.7%) were frail according to CGA, the median age was 73 years and 136 (57.9%) were female. In multivariable modelling, physical disability (Barthel index), cognitive impairment (IDEA cognitive screen), calf circumference, poor distance vision and problems engaging in social activities were found to be associated with frailty. After developing a scoring system, based on regression coefficients, a modified B-FIT screen (B-FIT 2) had an area under the receiver operating characteristic curve of 0.925, a sensitivity of 86.2% and a specificity of 88.8%. DISCUSSION The inclusion of items assessing nutrition, social support and sensory impairment improved the performance of the B-FIT. CONCLUSIONS The B-FIT 2 should be externally validated.

Abstract
(1) Introduction: With older adults, cognitive intervention programs are most often used for preventing or reversing a decline in cognitive functions, but it has been recently noted that there are insufficient high-quality research studies that report the effects of cognitive intervention on the cognitive functioning of older adults. (2) Objective: To analyze the available evidence concerning the effect of cognitive interventions for improving or maintaining the general cognitive status of older adults who present different cognitive levels. (3) Method: a review of studies published between 2010 and 2019 using the following databases: PubMed, PsycINFO, Cochrane, Google Scholar, ProQuest and Medline. (4) Results: We selected 13 systematic reviews and/or meta-analyses. The results showed that the cognitive intervention programs improved general cognitive functioning and specific cognitive functions regardless of the initial cognitive level; that cognitive decline was slowed in older persons with dementia; and there was improvement in activities of daily living. Regarding duration of the results, benefits were maintained for periods of 2 months to 5 years. (5) Conclusion: Cognitive interventions have proven effective for maintaining and/or improving cognitive functioning in older adults regardless of their initial cognitive status. Even so, there are few studies that follow up these results to see whether they are maintained in the long term and whether there is transfer to other skills of daily life. However, we were able to observe in the present review how the participants' cognitive level varied according to sociodemographic differences, and to identify which components of cognitive programs make them more effective. Based on the results found, we highlight the importance of designing cognitive intervention programs that meet these effectiveness criteria, in order to maximize the positive effects of such programs when working with a population of older adults.

Abstract
This scoping review mapped and synthesized published literature related to education and support services for individuals with dementia and their caregivers living rurally. Specifically, we investigated education and support service needs, availability and use of services, barriers to service access and use, and solutions to these barriers. Empirical, English-language articles (2,381) were identified within MEDLINE, CINAHL, PSYCINFO, and EMBASE. Articles were screened according to Arksey and O'Malley's (2005) five-stage scoping review methodology and the recommendations of Levac et al. (2010). Findings suggest limited availability of rural dementia-related support and education services, particularly respite care and day programs. Service use varied across studies, with barriers including low knowledge regarding services, practicality, and resource issues (e.g., transportation, financial), values and beliefs, stigma, and negative perceptions of services. Solutions included tailored and person-centred services, technological service provision, accessibility assistance, inter-organization collaboration, education regarding services, and having a "point of entry" to service use.

Abstract
BACKGROUND Alzheimer's disease and related dementias are associated with increasing health burden in low- and middle-income countries. Less well-recognized is the potential health burden experienced by other affected individuals, such as family caregivers. In this study, we sought to profile the burden of care and its association with symptoms of depression and anxiety among informal caregivers of people living with dementia in rural southwestern Uganda. METHOD We conducted a cross-sectional study of 232 family caregivers of people with dementia. The key measured variables of interest were caregiving burden (Zarit Burden Index) and symptoms of depression and anxiety (Depression Anxiety Stress Scales). We fitted multivariable regression models specifying depression and anxiety symptoms as the primary outcomes of interest and caregiving burden as the primary explanatory variable of interest. RESULTS Family caregivers of people with dementia experience significant caregiving burden, with each item on the Zarit Burden Index endorsed by more than 70% of study participants. Nearly half [108 (47%)] of caregivers had Zarit Burden Interview scores >60, suggestive of severe caregiving burden. In multivariable regression models, we estimated a statistically significant positive association between caregiving burden and symptoms of both depression [b = 0.42; 95% confidence interval (CI) 0.34-0.49] and anxiety (b = 0.37; 95% CI 0.30-0.45). CONCLUSION Family caregivers of people with dementia in rural Uganda experience a high caregiving burden, which is associated with symptoms of depression and anxiety. Interventions aimed at reducing caregiving burden may have important collateral mental health benefits.

Abstract
Objectives: We investigated the feasibility and clinical impact of a psychosocial intervention, Cognitive Stimulation Therapy (CST), to help manage dementia in a rural setting in Nigeria. Method: People with dementia were identified from a prevalence study in Lalupon in the south-west of Nigeria. Prior to this feasibility study CST was adapted for the setting and pilot by our team. Fourteen sessions of CST were provided over a 7-week period by a trained nurse specialist and occupational therapist. Change in quality of life was the main outcome. Results: Nine people were enrolled in CST. Significant improvements in cognitive function, quality of life (physical, psychosocial and environmental domains), physical function, neuro-psychiatric symptoms and carer burden were seen. Conclusions: CST appears to be feasible in this setting, although adaptation for low literacy levels, uncorrected visual and hearing impairment and work and social practices is needed. The clinical improvements seen were encouraging.

Abstract
INTRODUCTION In low/middle-income countries (LMICs), the prevalence of people diagnosed with dementia is expected to increase substantially and treatment options are limited, with acetylcholinesterase inhibitors not used as frequently as in high-income countries (HICs). Cognitive stimulation therapy (CST) is a group-based, brief, non-pharmacological intervention for people with dementia that significantly improves cognition and quality of life in clinical trials and is cost-effective in HIC. However, its implementation in other countries is less researched. This protocol describes CST-International; an implementation research study of CST. The aim of this research is to develop, test, refine and disseminate implementation strategies for CST for people with mild to moderate dementia in three LMICs: Brazil (upper middle-income), India (lower middle-income) and Tanzania (low-income). METHODS AND ANALYSIS Four overlapping phases: (1) exploration of barriers to implementation in each country using meetings with stakeholders, including clinicians, policymakers, people with dementia and their families; (2) development of implementation plans for each country; (3) evaluation of implementation plans using a study of CST in each country (n=50, total n=150). Outcomes will include adherence, attendance, acceptability and attrition, agreed parameters of success, outcomes (cognition, quality of life, activities of daily living) and cost/affordability; (4) refinement and dissemination of implementation strategies, enabling ongoing pathways to practice which address barriers and facilitators to implementation. ETHICS AND DISSEMINATION Ethical approval has been granted for each country. There are no documented adverse effects associated with CST and data held will be in accordance with relevant legislation. Train the trainer models will be developed to increase CST provision in each country and policymakers/governmental bodies will be continually engaged with to aid successful implementation. Findings will be disseminated at conferences, in peer-reviewed articles and newsletters, in collaboration with Alzheimer's Disease International, and via ongoing engagement with key policymakers.

Abstract
Abstract. Cognitive Stimulation Therapy (CST) is an internationally used, evidence-based psychosocial intervention for people with mild-to-moderate dementia. The present review thus aimed specifically to examine the reliability of the findings and the strength of the evidence obtained in studies on the CST protocol concerning any benefit in terms of cognitive functioning, perceived quality of life, psychological, behavioral, and everyday life functioning of people with dementia, and their family caregivers’ health status, quality of life, and burden of care. A systematic literature search on studies specifically adopting the CST protocol in patients with mild-to-moderate DSM-IV dementia – eventually involving their family members – was performed. A total of 238 papers were screened and 12 finally included in the qualitative analysis after inclusion/exclusion criteria were applied. The Jadad Scale and the Stroke Prevention and Educational Awareness Diffusion (SPREAD) method were used to appraise the studies’ methodological quality. Moderate levels of evidence emerged for general cognitive functioning, language comprehension and production, and quality of life. The levels of evidence were weaker for short-term memory, orientation, praxis, depression, social and emotional loneliness, behavior, and communication in people with dementia, and for their caregivers’ health status and anxiety symptoms. Albeit with the limited quality of reviewed evidence, and the need for more studies on CST, the present review highlights the value of this program as part of dementia care services to sustain the cognitive functioning and quality of life of people with dementia.

Abstract
UNLABELLED ABSTRACTBackground:The number of people living with dementia in sub-Saharan Africa (SSA) is expected to increase rapidly in the coming decades. However, our understanding of how best to reduce dementia risk in the population is very limited. As a first step in developing intervention strategies to manage dementia risk in this setting, we investigated rates of cognitive decline in a rural population in Tanzania and attempted to identify associated factors. METHODS The study was conducted in the rural Hai district of northern Tanzania. In 2014, community-dwelling people aged 65 years and over living in six villages were invited to take part in a cognitive screening program. All participants from four of the six villages were followed-up at two years and cognitive function re-tested. At baseline and follow-up, participants were assessed for functional disability, hypertension, and grip strength (as a measure of frailty). At follow-up, additional assessments of visual acuity, hearing impairment, tobacco and alcohol consumption, and clinical assessment for stroke were completed. RESULTS Baseline and follow-up data were available for 327 people. Fifty people had significant cognitive decline at two-year follow-up. Having no formal education, low grip strength at baseline, being female and having depression at follow-up were independently associated with cognitive decline. CONCLUSIONS This is one of the first studies of cognitive decline conducted in SSA. Rates of decline at two years were relatively high. Future work should focus on identification of specific modifiable risk factors for cognitive decline with a view to developing culturally appropriate interventions.

Abstract
PURPOSE Mild cognitive impairment (MCI) is associated with a higher risk of dementia and is becoming a topic of interest for pharmacological and nonpharmacological interventions. With advances in technology, computer-based cognitive exercises are increasingly integrated into traditional cognitive interventions, such as cognitive training. Another type of cognitive intervention involving technology use is cognitive engagement, consisting of involving participants in highly motivational and mentally challenging activities, such as learning to use a form of new digital technology. This study examined the feasibility and acceptability of a computerized cognitive stimulation (CCS) program and a computerized cognitive engagement (CCE) program, and then compared their effects in older adults with MCI. PATIENTS AND METHODS In this randomized study, data from 19 MCI patients were analyzed (n=9 in CCS and n=10 in CCE). The patients attended a group weekly session for a duration of 3 months. Assessments of cognitive and psychosocial variables were conducted at baseline (M0) and at the end of the programs (M3). RESULTS All of the participants attended the 12 sessions and showed a high level of motivation. Attrition rate was very low (one dropout at M3 assessment). At M3, the CCS participants displayed a significant improvement in part B of the Trail Making Test (TMT-B; p=0.03) and self-esteem (p=0.005), while the CCE participants showed a significant improvement in part A of the Trail Making Test (TMT-A; p=0.007) and a higher level of technology acceptance (p=0.006). The two groups did not differ significantly (p>0.05) in cognitive and psychosocial changes after the intervention. However, medium effect sizes (Cohen's d=0.56; 95% CI =-0.43:1.55) were found on the free recall, favoring the CCS group, as well as on TMT-A (d=0.51; 95% CI =-0.48:1.49) and technology acceptance (d=-0.65; 95% CI =-1.64:0.34), favoring the CCE group. CONCLUSION Both interventions were highly feasible and acceptable and allowed improvement in different aspects of cognitive and psychosocial functioning in MCI subjects.
