Abstract Introduction The prevalence of dementia in Tanzania, as in other developing countries is progressively increasing. Yet international screening instruments for mild cognitive impairment are lacking. The aim of this study was to determine the psychometrics and the diagnostic ability of the Montreal Cognitive Assessment 5 minutes protocol (MoCA-5-min) among older adult in the rural Tanzania. Methods The MoCA-5-min and the IDEA cognitive screening were concurrently administered through face to face to 202 community-dwelling older adults in Chamwino district. Exploratory factor analysis (EFA) using principal component method and oblique rotation was performed to determine the underlying factor structure of the scale. The concurrent, construct as well as predictive validities of the MoCA-5-min were examined by comparing its score with IDEA cognitive screening and psychiatrist’s diagnosis using DSM-V criteria respectively. Results The EFA found that all the MoCA-5-min items highly loaded into one component, with factor loading ranging from 0.550 to 0.879. The intraclass correlation coefficient for 6 weeks test-retest reliability was 0.85. Its strong significant correlation with the IDEA screening (Pearson's r = 0.614, p < 0.001) demonstrated a good concurrent validity. Using the psychiatrist’s rating as the gold standard, MoCA-5-min demonstrated the optimal cut-off score for MCI at 22, which yielded the sensitivity of 80% and specificity of 74%; and dementia at score of 16 giving a sensitivity of 90% and specificity of 80%. Upon stratifying the sample into different age groups, the optimal cut-off scores tended to decrease with the increase in age. Conclusion The MoCA-5-min is reliable and provides a valid and accurate measure of cognitive decline among older population in the rural settings of Tanzania. The use of varying cut-off scores across age groups may ensure more precise discriminatory power of the MoCA-5-min.

Montreal Cognitive Assessment

Abstract Objective The incidence of dementia in the sub-Saharan Africa is rising. However, screening tools for cognitive decline that fits their linguistic and cultural context are lacking. The aim of this study was to determine the accuracy of the Kiswahili version of Montreal Cognitive Assessment (K-MoCA) to detect mild cognitive impairment or dementia among older adults in the rural Tanzania. Methods We recruited 259 community-dwelling older adults in Chamwino district, Tanzania. The concurrent validity and discriminatory power of K-MoCA were examined by comparing its score with IDEA cognitive screening and psychiatrist’s diagnosis using DSM-V, respectively. All the questionnaires were administered in face-to-face interview. Results K-MoCA demonstrated acceptable reliability (Cronbach’s alpha = 0.780). Concurrent validity was evident by its significant correlation with the IDEA screening test (Pearson’s r = 0.651, p &lt; 0.001). Using the psychiatrist’s rating as the reference, the optimal cut-off score for MCI and dementia was 19 and 15, respectively, which yielded the sensitivity of 70% and specificity of 60% for MCI, and sensitivity of 72% and specificity of 60% for dementia. Further analysis indicated that education and age influence performance on K-MoCA. Conclusion Overall, the K-MoCA is a reliable and valid tool for measuring cognitive decline. However, its limited discriminatory power for MCI and dementia may be compromised by the cultural irrelevance of some items.

Community Dwelling Older Adults

Community-dwelling older adults have raised the scientific community’s interest during the COVID-19 era as their chronic conditions might be aggravated by the consequences of confinement. Digital devices in this field to monitor cognitive impairment are an emerging reality of an innovative nature. However, some groups may not have benefited from these developments as much as, for example, younger people. The aim of this manuscript is to carry out a review on the development of digital devices, and specifically virtual assistants, for the detection of cognitive impairment in older adults. After a screening process, eight studies were found under the given criteria, and this number was even smaller for those using virtual assistants. Given the opportunities offered by virtual assistants through techniques such as natural language processing, it seems imperative to take advantage of this opportunity for groups such as older adults.

Community Dwelling Older Adults

BACKGROUND Coronavirus disease 2019 has forced worldwide the implementation of unprecedented restrictions to control its rapid spread and mitigate its impact. The Spanish government has enforced social distancing, quarantine and home confinement. This restriction of daily life activities and separation from loved ones may lead to social isolation and loneliness with health-related consequences in community-dwelling older adults with mild cognitive impairment or mild dementia and their caregivers. Additionally, an inadequate access to healthcare and social support services may aggravate chronic conditions. Technology home-based interventions emerge for combating social isolation and loneliness preventing the risk of viral exposure. OBJECTIVE The aim of this cohort study is to explore, analyze and determine the impact of social isolation on: 1) cognition, quality of life, mood, technophilia and perceived stress of community-dwelling older adults with mild cognitive impairment or mild dementia, and on caregiver burden; 2) health and social care services access and utilization, and 3) cognitive, social and entertainment use of ICTs. METHODS This study will be conducted in the Spanish region of Andalucía (Málaga). In total 200 dyads, consisting of a person with mild cognitive impairment or mild dementia (PMCI/MD) and their informal caregiver will be contacted by telephone. Potential respondents will be participants of the SMART 4 MD (N=100) and TV-AssistDem (N=100) clinical trials. RESULTS The change in means in the variables will be analyzed comparing baseline results in the previous studies with those during and after confinement using the ANOVA test of repeated measures or the non-parametric Friedman test if appropriate. The performance of a multivariate analysis of variance (ANCOVA) to introduce possible covariates will also be contemplated. A 95% confidence level will be used. CONCLUSIONS If the hypothesis is proven, these findings will demonstrate the negative impact of social isolation due to the COVID-19 confinement on cognition, quality of life, mood, and perceived stress of community-dwelling older adults with mild cognitive impairment and mild dementia, the impact on technophilia, caregiver burden, and health and social care services access and utilization; and the cognitive, social and entertainment use of ICTs during the COVID-19 confinement and afterwards.

Aim: To determine effects of Kinect- based games on neurocognitive functions in older adults with mild cognitive impairment. Methodology: A quasi experimental pre-post trail was conducted on 18 mild cognitive impairment (MCI) older adults. The subjects were recruited to access cognitive impairment through purposive sampling technique. The inclusion criteria were elderly aged ≥ 50 years, both genders, able to read and write, whereas older adults with severe cognitive impairments, neurological disorders and un controlled comorbidities were excluded. Brain training was provided for 30 minutes with 5-minute warm-up time and 5-minute cool-down time for 6 weeks. Blind assessor measured readings at baseline and after six weeks. The outcome measures were Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MOCA), Trail making test A & B and verbal fluency test (Semantic &Phonemic). The data was analyzed at baseline and after six weeks of intervention Results: Significant improvements were observed in post-test measurements (p <0.05) in MMSE, MoCA, TMT A & B and verbal fluency (Semantic &Phonemic) tests after 6 weeks of treatment. Conclusion: Kinect-based virtual reality games are beneficial in improving cognitive abilities of older adults with mild cognitive impairment.
