Initial Adaptation of the General Cognitive Assessment Battery by Cognifit™ for Bulgarian Older Adults

Abstract Background Delirium is a common geriatric problem associated with poor outcomes. Subsyndromal delirium (SSD) is characterized by the presence of certain symptoms of delirium yet, not satisfying the definition of full-blown delirium, defined by categorical elements, and is usually referred to as the presence of one or more symptoms in the confusion assessment method (CAM). This study aimed to investigate the prevalence and risk factors of delirium and SSD in older adults admitted to the hospital. Five hundred eighty-eight elderly (above 65 years) Egyptian patients were recruited from January 2019 to February 2020. After explaining the purpose of the study and assuring the confidentiality of all participants, an informed consent was obtained from the participant or a responsible care giver for those who were not able to give consent. All patients were subjected ‘on admission’ to thorough history taking, clinical examination, and comprehensive geriatric assessment including confusion assessment tools, mini-mental state examination, and functional assessment using Barthel index score. Results The current study showed that 19.6% of patients had delirium and 14.1% of patients had SSD with combined prevalence of 33.7%. Most common causes included metabolic, infection, organic brain syndrome, and dehydration. The current study reported significant proportionate relation between cognitive assessment and functional ability, so patients with a score of 23 MMSE had good functional ability, while cognitive assessment using mini-mental score shows inversed relation to delirium and SSD using CAM score. Conclusion Delirium is independently associated with adverse short-term and long-term outcomes, including an increase in mortality, length of hospital stay, discharge to an institution, and functional decline on discharge. Subsyndromal delirium (SSD) is characterized by the presence of certain symptoms of delirium, not yet satisfying the definition of full-blown delirium but it can identify patients with early cognitive and functional disabilities, and because of high prevalence of delirium and SSD. Efforts to prevent or early detection may identify patients who warrant clinical attention.

Increased Risk

Abstract Home-based cognitive assessment (HBCA) services are emerging as a convenient alternative to in-clinic cognitive assessment and may aid in mitigating barriers to detecting cognitive impairment (CI). It is unknown which older adults would be likely to participate in HBCA. Here we investigated the role of age and Subjective Cognitive Decline (SCD). SCD has demonstrated an increased risk for progression to CI/dementia. A nation-wide community-dwelling sample of 494 adults age 50+ were recruited via Amazon Mechanical Turk to complete an online survey assessing perceptions around HBCA and SCD. Our sample was 91.9% White and 66.8% female. It consisted of 174 respondents aged 50-60, 265 aged 61- 70, and 55 aged 71-79. Age groups were comparable with respect to their acceptance of cognitive assessment (Range 4-20, higher score=higher acceptance, 7.9±3.3, 8.15±3.2, 8.05±3.43) and SCD-Q total (43.1±5.8, 43.2±5.7, 43.3±5.7). Correlation analysis revealed a relationship between SCD-QSCD total and perceived likelihood of participation in HBCA for those ages 61-70 (r(263) = .222 p = .000), but not for ages 50-60 or 71-79 (r(172) = .102 p = .152; r(53) = -.102 p = .458). Our findings suggest that SCD influences the likelihood of participation in HBCA for older adults’ transitioning to old age (61-70). Findings show that for adults transitioning into old age (61-70), perceived cognitive state influences their likelihood of participation in HBCA. Importantly, concerns about CI/dementia may generate more favorable perceptions of HBCA for this group.

Assessment Battery

Contexto: A Esclerose Múltipla (EM) é uma doença desmielinizante crónica que pode envolver alterações cognitivas e executivas. As alterações executivas, relacionadas essencialmente com o lobo frontal, podem ser subdiagnosticadas, uma vez que os instrumentos utilizados na EM são extensos e complexos, podendo os seus resultados ser comprometidos pelos níveis de fadiga que poderão daí decorrer. A Bateria de Avaliação Frontal (FAB) é de aplicação rápida e simples e avalia as funções do lobo frontal. Objetivo: Explorar as propriedades psicométricas da FAB numa amostra de doentes com EM. Métodos: No estudo avaliaram-se 68 doentes com EM e 81 indivíduos sem diagnóstico de doença neurológica (amostra de controlo) com a FAB, a Subescala executiva do Montreal Cognitive Assessment/MoCA-E e o Teste de Fluências Verbais Fonéticas/TFVF. Vinte e nove doentes foram reavaliados com a FAB (intervalo 4-8 semanas). Resultados: Na amostra com EM, a consistência interna revelou-se adequada e a estabilidade temporal situou-se entre moderada a alta nas subescalas Semelhanças, FluênciasLexicais, Séries Motoras de Luria e Go-no-Go. A FAB correlacionou-se de forma elevada com o MoCA-E e TFVF, atestando a sua validade convergente, e a sua estabilidade temporal teste-reteste revelou-se adequada. A amostra com EM teve pontuações significativamente inferiores nas subescalas Fluências Lexicaise Séries Motoras de Luria comparativamente com a amostra de controlo(p < 0,05). Na EM, a FAB discriminou os níveis de escolaridade (p < 0,001) e a subescala Séries Motoras de Luria diferenciou os padrões de EM (p < 0,05). Conclusões: A FAB apresenta propriedades psicométricas adequadas para avaliar as funções do lobo frontal em doentes com EM, devendo integrar a sua avaliação neuropsicológica para auxiliar no correto encaminhamento terapêutico. Adicionalmente, a subescala das Fluências Lexicais parece ser importante para avaliar estes doentes, tendo potencial para o nível I do rastreio da disfunção frontal na EM.

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.

Reliability Coefficients

Abstract Background Mild cognitive impairment (MCI) is a transition stage between healthy cognition and dementia, and is linked to poorer sleep. Objective, reliable, and low-burden field methods to measure older adult sleep are also currently needed. The MotionWatch8© (MW8) wrist-worn actigraph provides estimates of sleep with 14 days of observation; however, there may be underlying differences in the reliability of sleep estimates based on MCI status. We therefore investigated the number of MW8 monitoring days required to estimate sleep in older adults with MCI and without. Methods Older adults (55+ years; N=151) wore the MW8 for ≥14 days. The Montreal Cognitive Assessment was used to categorize participants with probable MCI (scores of <26/30) and participants without MCI (≥26/30). We calculated intra-class reliability coefficients for 1-, 7-, and 14-days of wear-time, and performed Spearman-Brown predictions to determine the number of monitoring days needed for an ICC=0.80. Results Older adults with MCI were older ( p <0.01), more likely to be male ( p =0.03), and had shorter sleep duration ( p <0.01). Spearman-Brown analyses indicated that the number of monitoring days needed for an ICC=0.80 in older adults with probable MCI was 7 days for sleep duration, 4 days for fragmentation, and 4 days for efficiency; adults without MCI required 4 days for duration, 6 days for fragmentation, and 3 days for efficiency. Conclusions Our results indicate that while the reliability of MW8 estimates of sleep differs based on cognitive status, 7 days of MW8 monitoring provides reliable estimates of sleep for adults with MCI and those without.
