A systematic review on prognostic factors and models for changes in quality of life and depressive symptoms after multi-domain cognitive training in healthy older adults: Who benefits?

BACKGROUND: As we age, cognitive abilities decline which can lead to a decrease in quality of life (QoL) and an increase in depressive symptoms even in healthy (i.e., non-clinical) older adults. Cognitive trainings (CT) are a promising approach to not only improve cognition, but also QoL and mood. However, it is unclear which prognostic factors are associated with changes in QoL and depression after CT. OBJECTIVE: To identify prognostic factors and models of changes in QoL and depressive symptoms after a multi-domain CT in healthy older adults. METHODS: MEDLINE, Web of Science Core Collection, CENTRAL and PsycInfo were systematically searched for multi-domain CT studies in healthy older adults until August 2022. Studies investigating prognostic factors and/or models on QoL and depressive symptoms were included. Risk of bias was assessed using the QUIPS and the PROBAST tool. RESULTS: Our search revealed N = 12,916 studies, of which only 6 could be included in the review. Prognostic factors included were sociodemographics, cognitive reserve, cognitive baseline level, and cognitive change. However, data were too rare and heterogenous regarding the assessment measures of QoL and depressive scores, the used multi-domain CT and the investigated prognostic factors to draw clear conclusions or conduct meta-analyses. CONCLUSION: There is an urgent need for research on prognostic factors and models of changes in QoL and depressive symptoms after CT in healthy older participants as they could help to tailor interventions to individuals in terms of future precision medicine approaches.

Which Test Is the Best to Assess Visuo-Cognitive Impairment in Patients with Parkinson's Disease with Mild Cognitive Impairment and Dementia? A Systematic Review and Meta-Analysis.

BACKGROUND: Visuo-cognitive impairment is common in patients with Parkinson's disease with mild cognitive impairment (PD-MCI) and constitutes a prognostic factor for the conversion to Parkinson's disease dementia (PDD). However, systematic analyses on which neuropsychological tests are most suitable to assess visuo-cognition in PD-MCI and PDD and to differentiate these cognitive stages are lacking. OBJECTIVE: To review neuropsychological tests used to assess visuo-cognition including visuo-perceptual and visuo-spatial processing, visuo-constructive copying and drawing on command abilities; and to identify the visuo-cognitive subdomain as well as tests most suitable to discriminate between PD-MCI and PDD. METHODS: MEDLINE, PsycINFO, Web of Science Core Collection, and CENTRAL were systematically searched for relevant studies assessing visuo-cognitive outcomes in patients with PD-MCI and PDD. Risk of bias was assessed using a customized form based on well-established tools. Random-effect meta-analyses were conducted. RESULTS: 33 studies were included in the systematic review. Data of 19 studies were entered in meta-analyses. Considerable heterogeneity regarding applied tests, test versions, and scoring systems exists. Data indicate that visuo-constructive command tasks are the subdomain best suited to discriminate between PD-MCI and PDD. Furthermore, they indicate that the Rey-Osterrieth-Complex-Figure Test (ROCF), Corsi Block-Tapping Test, Judgment of Line Orientation (JLO), and Clock Drawing Test (CDT) are tests able to differentiate between the two stages. CONCLUSION: We provide suggestions for suitable visuo-cognitive tests (Corsi Block-Tapping Test, or JLO, ROCF, CDT) to improve diagnostic accuracy. Methodological challenges (e.g., heterogeneity of definitions, tests) are discussed and suggestions for future research are provided.

Psychosocial well-being and quality of life in siblings of children with congenital heart disease: A systematic review.

Congenital heart disease (CHD) is a major global health problem. Until recently, the siblings of this group did not receive much attention. This review, conducted from November 2019 to October 2020, aims to summarize knowledge about psychosocial well-being and quality of life (QoL), associated factors, and interventions for siblings of children with CHD. Systematic searches were conducted in PubMed, PsycINFO, PsycARTICLES, Web of Science via EBSCOhost, and CENTRAL. Twelve articles were included. Results showed that psychosocial well-being was impaired in 14% to 40% of siblings. Negative impact of illness was highest for CHD siblings compared to siblings of children with cancer, cystic fibrosis, or diabetes. QoL was impaired in up to one-third. Siblings of children with CHD and cancer rated their QoL lower than those of siblings of children with cystic fibrosis or type-1 diabetes. Associated factors were sibling age, gender, socioeconomic status, miscarriage, previous sibling death, visibility of illness, and severity of condition. Only one of two interventions focused on siblings of CHD children. Although data are scarce and inhomogeneous, it indicates that siblings of CHD children suffer from lower psychosocial well-being and QoL than siblings of children with other chronic conditions. Interventions to improve their situation should be developed.

Effects of Sociodemographic Variables and Depressive Symptoms on MoCA Test Performance in Native Germans and Turkish Migrants in Germany.

The validity of the Montreal Cognitive Assessment (MoCA) in migrants is questionable, as sociodemographic factors and the migration process may influence performance. Our aim was to evaluate possible predictors (age, education, sex, depression, and migration) of MoCA results in Turkish migrants and Germans living in Germany. Linear regression models were conducted with a German (n = 419), a Turkish (n = 133), and an overall sample. All predictor analyses reached statistical significance. For the German sample, age, sex, education, and depression were significant predictors, whereas education was the only predictor for Turkish migrants. For the overall sample, having no migration background and higher education were significant predictors. Migration background and education had an impact on MoCA performance in a sample of German and Turkish individuals living in Germany. Thus, culture-specific normative data for the MoCA are needed, and the development of culture-sensitive cognitive screening tools is encouraged.

Simultaneous self-other integration and segregation support real-time interpersonal coordination in a musical joint action task.

The ability to distinguish between an individual's own actions and those of another person is a requirement for successful joint action, particularly in domains such as group music making where precise interpersonal coordination ensures perceptual overlap in the effects of co-performers' actions. We tested the hypothesis that such coordination benefits from simultaneous integration and segregation of information about 'self' and 'other' in an experiment using a musical joint action paradigm. Sixteen pairs of individuals with little or no musical training performed a dyadic synchronization task on a pair of electronic music boxes. The relationship between pitches produced by paired participants (same vs. different) and the relationship between movement frequencies required to trigger synchronous tones (congruent vs. incongruent) were varied in a repeated measures design. The results indicate that interpersonal coordination was most accurate when sounds were different in pitch but movement frequency was congruent. Under other conditions, participants often drifted apart, resulting in poor coordination, especially with same sounds and incongruent movements across co-performers. These findings suggest that interpersonal coordination was facilitated when simultaneous self-other integration and segregation occurred across sensory modalities in an asymmetrical manner where pitch relations favoured segregation via auditory streaming while movement congruence favoured integration via visuo-motor coupling. Such self-other representational balance may enable co-performers to maintain autonomous control while attending, anticipating, and adapting to each other's timing when joint action requires precise temporal coordination.

Prognostic Factors and Models for Changes in Cognitive Performance After Multi-Domain Cognitive Training in Healthy Older Adults: A Systematic Review.

Background: Cognitive Training (CT) may contribute to the maintenance and even enhancement of cognitive functions in healthy older adults. However, the question who benefits most from multi-domain CTs is still highly under-investigated. Objective: The goal is to investigate prognostic factors and models for changes in cognitive test performance in healthy older adults after a multi-domain CT. Methods: The data bases MEDLINE, Web of Science Core Collection, CENTRAL, and PsycInfo were searched up to July 2019. Studies investigating prognostic factors and/or models on cognitive outcomes (global cognition, memory, attention, executive functions, language, visuo-spatial abilities) after conducting a multi-domain CT in healthy older adults were included. Risk of Bias was assessed using the QUIPS and the PROBAST tool. Results: 23 prognostic factor and model studies were included. Results indicate a high heterogeneity regarding the conducted multi-domain CTs, the investigated prognostic factors, the investigated outcomes, and the used statistical approaches. Age and neuropsychological performance at study entry were the most investigated predictors, yet they show inconsistent results. Conclusion: Data on prognostic factors and models of changes after multi-domain CT are still too rare and inconsistent to draw clear conclusions due to statistical shortcomings and low reporting quality. Approaches for future research are outlined. Registration: https://www.crd.york.ac.uk/prospero/, ID: CRD42020147531.

Long-Term Effectiveness of Guided Self-Help for Parents of Children With ADHD in Routine Care-An Observational Study.

Objective:To assess long-term effectiveness of guided self-help for parents of children with ADHD under routine care conditions. Method: 6- to 12-year-old children diagnosed with ADHD were enrolled in an observational study on a 1-year telephone-assisted parent-administered behavioral intervention. N = 136 families who completed the intervention participated in a follow-up assessment. Pre-, post-, and follow-up data were analyzed by repeated measures ANOVA with planned contrasts. Clinical significance was analyzed according to the reliable change index. Results: Child ADHD symptoms (primary outcome), oppositional defiant disorder (ODD) symptoms, overall behavioral problems, and quality of life improved during the intervention. There was a further improvement in ADHD symptoms at follow-up, with a medium effect size. Improvements during treatment in ODD symptoms, overall behavioral problems, and quality of life were maintained at follow-up. Conclusion: The findings suggest that telephone-assisted self-help interventions may result in a long-term reduction of child behavior problems.
