Abstract
Aging is often accompanied by a decline in cognitive functions, with memory being particularly affected. Recent studies suggest that cognitive training sessions that teach memory strategies relevant to daily life may benefit seniors who live in the community. However, it is possible that the cognitive improvement observed in these programs results from the social encounters embedded in them. In this study, we aimed to investigate the effect of a social cognitive training group, which met regularly for an extended period, on enhancing cognitive indices compared to a control group that only received social engagement meetings without training. Sixty-six participants with a mean age of 78 took part in 12 sessions of a social engagement group, with or without strategy training. Cognitive performance was assessed before and after training using four memory tasks, two similar to the trained tasks (near-transfer tasks) and two novel (far-transfer tasks). Both groups showed a slight improvement in most of the evaluation tasks, but the cognitive training combined with social engagement group showed a significant improvement in the Word Recall and Verbal Fluency tests compared to the social engagement group without training. Our findings suggest that cognitive training sessions may be a useful tool in promoting cognitive improvement among older adults living in the community, even beyond the improvement obtained from the social engagement that occurs during the training sessions.Trial registration number:NCT05016336.

Abstract
BACKGROUND Multi-domain interventions effectively prevent dementia in clinical settings; however, their efficacy within local communities is unclear. This study assesses the feasibility of an adapted multi-domain intervention for dementia prevention in community-dwelling older adults. METHODS The single-arm trial enrolls 60 participants from two Obu City communities, Japan. PRIMARY OUTCOME participant retention in the adapted multi-domain intervention; secondary outcomes: health and implementation outcomes. Over 12 months, a team of researchers and public health nurse oversees the study in the first half, gradually shifting the management to public health nurses in the second half. Using the Framework for Reporting Adaptations and Modifications-Enhanced, the clinical programme is adjusted for the local community. It includes a 60-minute exercise and 30-minute group sessions, targeting lifestyle, diet, and social participation. DISCUSSION This pioneer study evaluates the feasibility of an adapted intervention programme for dementia prevention in a community setting. Challenges in disseminating dementia prevention programmes warrant further investigation into effective implementation as well as strategies and methods to appeal to the target population. Upon confirming this programme's feasibility, future studies can further evaluate its broader effectiveness. TRIAL REGISTRATION The protocol is registered with the Clinical Trials Registry (UMIN-CTR) of the University Hospital's Medical Information Network, under registration number UMIN000050581.

Efficacy of ICT-based interventions in improving psychological outcomes among older adults with MCI and dementia: A systematic review and meta-analysis. Ageing Res Rev 2022; 82:101781. [PMID: 36343879 DOI: 10.1016/j.arr.2022.101781] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2022] [Revised: 10/31/2022] [Accepted: 11/03/2022] [Indexed: 11/06/2022]
Abstract
The purpose of this systematic review and meta-analysis was to investigate empirical evidence about the effectiveness of Information and Communication Technology-based interventions (ICTs) on different psychological outcomes in adults aged over 60 years with Mild Cognitive Impairment (MCI) or dementia. We conducted a systematic search on Pubmed, Web of Science, Scopus, and PsycInfo with publication year between January 2010 up to April 2021. Any pre-post quantitative intervention study with at least one of the following domains examined: quality of life (QoL), psychological well-being, social interaction, engagement, mood, anxiety, stress, loneliness, self-efficacy, or self-esteem was included. The risk of bias and quality of evidence were assessed using tools based on the Cochrane Handbook for Systematic Review of Interventions criteria. Forty-eight studies with a total of 1488 participants met the selection criteria. Because of the high heterogeneity, we ran nine different random effects meta-analyses divided by outcome and type of cognitive decline which indicated that these treatments were ineffective overall, with some exceptions. Only anxiety (small effect size =-0.375 [-0.609; -0.140]) and behavioral symptoms (BS) (medium effect size =-0.585 [-1.019; -0.152]) in people with dementia (PwD) were found to change significantly. Moreover, effect sizes for QoL in dementia and for mood in people with MCI became significant when moderated by type of ICT, living situation, and experimental setting. In particular, Virtual Reality (VR) appeared to be more effective than other devices for both PwD and MCI, and nursing homes were found to be the best setting for administering these treatments. The trim and fill method found no evidence of publication bias in any of the 9 analyses. However, quality of evidence within (RoB 2, RoB 2 Crossover, ROBINS) and across (GRADE assessment) studies was low, thus these findings should be interpreted with caution. In general, ICT-based intervention can be considered a promising approach for improving anxiety and BS in PwD, and for improving QoL in PwD and mood in people with MCI, specifically when VR is used, when participants live in nursing homes, and when interventions are carried out in nursing homes.1.

The Effectiveness of Computerized Cognitive Training Combined With Whole Body Cryotherapy in Improving Cognitive Functions in Older Adults. A Case Control Study. Front Psychiatry 2021; 12:649066. [PMID: 34248698 PMCID: PMC8267365 DOI: 10.3389/fpsyt.2021.649066] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2021] [Accepted: 06/01/2021] [Indexed: 11/13/2022] Open
Abstract
Objectives: Subjective Cognitive Decline (SCD) and Mild Cognitive Impairment (MCI) are common in elderly population, and constitute a high-risk group for progression to dementia. Innovative, complex, and engaging non-pharmacological methods of cognitive stimulation, implementable at this stage, are needed. The aim of the study was to determine the effect of Computerized Cognitive Training (CCT) combined with Whole Body Stimulation (WBC) on cognitive functions of older adults with SCD and MCI. Methods: A 9-week single-blind pre/post case control trial was conducted. The study enrolled 84 adults aged 60 or older, allocated to one of two intervention groups: EG; CCT with psychoeducation, EG2; CCT with psychoeducation and 10 WBC sessions, or the control group (CG), which comprised patients receiving usual care. The primary outcome measures were cognitive functions evaluated with MoCA scale and several other neuropsychological tools. Depressive symptoms assessed with the GDS scale constituted the secondary outcome measures. Results: The results show evidence for increased performance in the assessment of general cognitive functioning in both EGs (p ≤ 0.05). Significant improvement was also visible in several cognitive domains, such as verbal fluency (EG1 & EG2), learning ability and immediate memory (EG1 & EG2), delayed memory (EG2), attentional control (EG1), and information processing (EG2) (p ≤ 0.05). However, only in the group with combined interventions (CCT + WBC) the participants presented significantly less depressive symptoms (p ≤ 0.05). Conclusions: The results of the study suggest that CCT, especially in combination with WBC, might be a practical and effective method of improving cognitive performance. Moreover, this combination leads to a reduction of depressive symptoms.

A Systematic Review of Effect Studies. J Clin Med 2021; 10:604.

Abstract
There is increasing interest in the use of technology to support social health in dementia. The primary objective of this systematic review was to synthesize evidence of effectiveness of digital technologies used by people with dementia to improve self-management and social participation. Records published from 1 January 2007 to 9 April 2020 were identified from Pubmed, PsycInfo, Web of Science, CINAHL, and the Cochrane Central Register of Controlled Trials. Controlled interventional studies evaluating interventions based on any digital technology were included if: primary users of the technology had dementia or mild cognitive impairment (MCI); and the study reported outcomes relevant to self-management or social participation. Studies were clustered by population, intervention, and outcomes, and narrative synthesis was undertaken. Of 1394 records identified, nine met the inclusion criteria: two were deemed to be of poor methodological quality, six of fair quality, and one of good quality. Three clusters of technologies were identified: virtual reality, wearables, and software applications. We identified weak evidence that digital technologies may provide less benefit to people with dementia than people with MCI. Future research should address the methodological limitations and narrow scope of existing work. In the absence of strong evidence, clinicians and caregivers must use their judgement to appraise available technologies on a case-by-case basis.

Serum amino acid profiles in patients with mild cognitive impairment and in patients with mild dementia or moderate dementia. Amino Acids 2021; 53:97-109.

Abstract
Neurodegenerative disorders are one of the greatest global challenges for social and health care in the twenty-first century. Nowadays, determination of cerebrospinal fluid biomarkers for early diagnosis is served by a complex sample preparation procedure with limited diagnostic accuracy. Furthermore, neuroimaging methods are expensive, time-consuming and are not readily available for use as a complimentary and common screening method. Recently, researchers have shown an increased interest in the identification and characterization of new blood biomarkers of dementia to minimize the limitations associated with the current methods of biomarker determination. Amino acids play many important roles in the central nervous system, acting as neuromodulators, neurotransmitters and regulators of energy metabolism. The aim of this study was to evaluate if serum amino acid levels change along the continuum from no cognitive impairment to moderate dementia, and to identify putative biomarkers for early diagnosis of neurodegenerative diseases. Serum levels of 16 amino acids were determined in 3 groups of patients-22 with mild cognitive impairment, 45 with mild dementia and 28 with moderate dementia-by high-performance liquid chromatography (HPLC) with fluorescence detection using AccQ Tag column (Waters). The most exciting result is the significantly elevated concentration of arginine in patients with both stages of dementia as compared to mild cognitive impairment individuals. Recent accumulating evidence suggests the implication of changed arginine metabolism in the pathogenesis of neurodegenerative diseases. We conclude that amino acids profiling might be helpful in searching for biomarkers of neurogenerative diseases. In the present study, we discovered that arginine in plasma may have a putative diagnostic value for dementia.
