Effectiveness of reminiscence therapy in reducing agitation and depression and improving quality of life and cognition in long-term care residents with dementia: A systematic review and meta-analysis

The influence of socio-cognitive mindfulness, moral sensitivity and dementia communication behaviors on dementia nursing performance of nurses in long-term care hospitals: a cross-sectional study

BACKGROUND

By incorporating socio-cognitive mindfulness which has been under-examined in the nursing field, this study investigated the relationships between socio-cognitive mindfulness, moral sensitivity, dementia communication behaviors, and dementia nursing performance of nurses in long-term care hospitals. This study also examined the factors influencing nurses' dementia nursing performance.

METHODS

A cross-sectional study was conducted with 209 nurses from long-term care hospitals in Korea. Data were collected between August 1 and August 31, 2022. Participants completed the questionnaire assessing their socio-cognitive mindfulness, moral sensitivity, dementia communication behaviors, and dementia nursing performance. Pearson's correlation and hierarchical multiple regression analysis were performed for data analysis.

RESULTS

Dementia nursing performance of the nurses in long-term care hospitals was positively related to their socio-cognitive mindfulness, moral sensitivity, and dementia communication behaviors. Furthermore, nurses' dementia communication behaviors, moral sensitivity, and total clinical career, in that order, were found to be the factors influencing their dementia nursing performance.

CONCLUSION

The findings indicate that the higher socio-cognitive mindfulness, moral sensitivity, and dementia communication behaviors, the higher dementia nursing performance, and that higher dementia nursing performance is associated with better dementia communication behaviors, greater moral sensitivity, and more extensive clinical experiences. This study provides a foundation for developing effective interventions to enhance dementia nursing performance in the future. To improve dementia nursing performance of nurses in long-term care hospitals, it is necessary to improve dementia communication behaviors and moral sensitivity, and prepare multilateral countermeasures to maintain nurses' clinical careers.

Effects of reminiscence therapy on cognition, agitation, and quality of life in older adults with dementia receiving long-term care

BACKGROUND

Dementia is one of the most common neuropsychiatric conditions in older adults. Despite many older adults with dementia receiving long-term care (LTC), few studies have been conducted in Turkey on reminiscence therapy (RT) influencing neuropsychiatric symptoms and quality of life in people with dementia receiving LTC. This study aimed to investigate the effect of RT on cognition, agitation, and quality of life in older adults with dementia receiving LTC in Turkey.

METHODS

The study population consisted of 100 older adults living in a LTC centre in a province. The size of the research group was calculated using the power analysis method, and 54 older adults were included in the study, 27 each in the RT and control (C) groups. Data collection forms Mini-Mental State Examination (MMSE), Cohen-Mansfield Agitation Inventory (CMAI), and the Alzheimer's Disease Quality-of-Life Scale (AD-QOL) were applied to the RT and C groups before RT (T0 ), 1 week after RT (T1 ), 1 month after RT (T2 ), and 3 months after RT (T3 ) to evaluate the effectiveness of the intervention. Mean, standard deviation, ratio, percentile, Fisher's exact test, Pearson Chi-square test, Mann-Whitney U-test, and Friedman test were used in analyzing the data.

RESULTS

Older adults in the RT and C groups were similar regarding sociodemographic characteristics, institutional care, and life models (P > 0.05). When comparing the T3 values of MMSE, CMAI, and AD-QOL total scores with the T0 values, a significant difference was observed between the groups, favouring the RT group (P < 0.001).

CONCLUSION

Individual RT may benefit cognition, agitation, and quality of life of older adults with dementia residing in a LTC centre.

Effects of reminiscence interventions on depression and anxiety: a meta-analysis of randomized controlled trials

OBJECTIVES

The goal of the present meta-analysis was to compare effects of reminiscence interventions on depression and anxiety across different target groups.

METHODS

Systematic search in electronic data bases and cross-referencing identified 195 randomized controlled trials that were included in random-effects meta-analysis.

RESULTS

Reminiscence interventions resulted, on average, in moderate improvement of depressive symptoms and small-to-moderate improvements of anxiety symptoms. Life review therapy for individuals with elevated psychological symptoms tended to be more effective (with moderate to strong improvements) than life review with nonclinical samples and simple reminiscence. Effects were similar for individuals with cognitive impairment, physical illness and general community-based samples. Intervention effects varied, in part, by intervention length, kind of control condition, publication status, and region where the study was conducted.

CONCLUSIONS

We conclude that reminiscence interventions should be offered for all adults interested in reflecting on their past, although adaptations of intervention contents can be made according to the needs of potential participants.

Mild cognitive impairment prediction and cognitive score regression in the elderly using EEG topological data analysis and machine learning with awareness assessed in affective reminiscent paradigm

Introduction

The main objective of this study is to evaluate working memory and determine EEG biomarkers that can assist in the field of health neuroscience. Our ultimate goal is to utilize this approach to predict the early signs of mild cognitive impairment (MCI) in healthy elderly individuals, which could potentially lead to dementia. The advancements in health neuroscience research have revealed that affective reminiscence stimulation is an effective method for developing EEG-based neuro-biomarkers that can detect the signs of MCI.

Methods

We use topological data analysis (TDA) on multivariate EEG data to extract features that can be used for unsupervised clustering, subsequent machine learning-based classification, and cognitive score regression. We perform EEG experiments to evaluate conscious awareness in affective reminiscent photography settings.

Results

We use EEG and interior photography to distinguish between healthy cognitive aging and MCI. Our clustering UMAP and random forest application accurately predict MCI stage and MoCA scores.

Discussion

Our team has successfully implemented TDA feature extraction, MCI classification, and an initial regression of MoCA scores. However, our study has certain limitations due to a small sample size of only 23 participants and an unbalanced class distribution. To enhance the accuracy and validity of our results, future research should focus on expanding the sample size, ensuring gender balance, and extending the study to a cross-cultural context.

The effect of virtual reminiscence therapy on depression and anxiety in patients with gastric cancer undergoing chemotherapy

PURPOSE

To determine the effect of virtual reminiscence therapy on depression and anxiety in patients with gastric cancer (PwGC) undergoing chemotherapy.

METHODS

In this quasi-experimental study, we randomly allocated 152 PwGC who met the inclusion criteria as 1:1 ratio to control (N = 76) and intervention (N = 76) groups. The patients in the control group received routine post-chemotherapy care, while those in the intervention group received reminiscence therapy over the phone in addition to routine care. The participants of both groups completed Beck's Depression Inventory and Zung's Self-rating Anxiety Scale before the study, 6 weeks after the beginning of the study, and 3 months after the intervention.

RESULTS

Although the mean depression score before chemotherapy indicated moderate depression in both groups, the reminiscence therapy group showed a significant reduction in the depression score compared to the control group (P < 0.001) following intervention. The mean anxiety scores indicated mild to moderate anxiety in both groups, which was later placed within the normal range, there was a significant difference between the two groups. Intra-group comparison revealed that the mean depression and anxiety scores decreased significantly in the reminiscence therapy group (P < 0.001).

CONCLUSION

This study indicated that virtual reminiscence therapy can decrease anxiety and depression in PwGC undergoing chemotherapy. Therefore, it can be a supportive psychological method for these patients.

Improved Mental Health, Social Connections and Sense of Self: A Mixed Methods Systematic Review Exploring the Impact and Experience of Community Reminiscence Programs

Older people can experience health and social challenges such as loneliness, depression, and lack of social connectedness. One initiative that has been trialed to address these challenges is reminiscence programs. These programs can include music, art, photographs, sports, and general discussion to stimulate memories. This review aimed to systematically search for literature that explored the impact and experience of reminiscence programs for older people living in the community for the purposes of informing community programming. The PICOS framework was used to develop the review parameters and search strategy. Qualitative and quantitative research focused on community-based reminiscence programs were included. Commercially produced databases and grey literature were searched. The Critical Appraisal Skills Program qualitative critical appraisal tool and McMaster quantitative critical appraisal tool were used to assess the methodological quality of the included studies. Quantitative data were descriptively synthesized, and qualitative data were thematically analyzed, with each reported separately. Twenty-seven studies were included in the review. All quantitative studies (n = 17) provided clear information regarding the purpose, sample size, and justification. The measures adopted were reliable and valid. All studies reported clear data collection/analysis information and statistically significant findings. All qualitative studies (n = 10) clearly articulated a purpose with nine clearly describing recruitment, data collection, and researcher relationship. Synthesis of quantitative data demonstrated positive findings through a reduction in depression, anxiety, and loneliness and improvements in quality of life and mastery. These findings were supported and broadened by qualitative findings with three key themes identified: program processes, program ingredients, and program benefits. Providing opportunities for older adults to come together to tell stories about their past experiences may positively contribute to social outcomes. As reminiscence programs gain popularity, their implementation in practice should be underpinned by clear and reproducible practices.

Transcultural Pilot Study of the Efficacy of Reminiscence Therapy for Mexican and Spanish Older Adults with Different Levels of Cognitive Decline

The main objective for this study is to analyze the impact of a positive reminiscence therapy program (REMPOS) in cognitive functioning and depressive symptomatology for older adults in different vital situations (healthy aging, mild cognitive impairment, and Alzheimer's disease).This is a transcultural comparative study (older people from Spain and Mexico). A randomized design with pre-posttest measurement and twelve groups was formulated, during a period of six months of intervention (3 in Mexico and 3 in Spain). The design had: 6 experimental groups with REMPOS intervention (3 in Mexico and 3 in Spain) during a period of six months and 6 control groups that received cognitive stimulation.While a key aspect of this study is the cross-cultural differences, an important part is to determine whether each experimental group had similar results in terms of the change in magnitude between the pre and post analysis. In general, intervention significantly improved cognitive function and decreased depressive symptoms.These findings provide further evidence about the efficacy of the REMPOS therapy between different types of aging and both geographical and cultural contexts (Spain and Mexico).

The Application of Fully Immersive Virtual Reality on Reminiscence Interventions for Older Adults: Scoping Review

BACKGROUND

The increasing number of older adults with mental, behavioral, and memory challenges presents significant public health concerns. Reminiscence is one type of nonpharmacological intervention that can effectively evoke memories, stimulate mental activities, and improve psychological well-being in older adults through a series of discussions on previous experiences. Fully immersive virtual reality (FIVR) may be a useful tool for reminiscence interventions because it uses realistic virtual environments connected to a person's significant past stories.

OBJECTIVE

This review aims to examine empirical evidence regarding the application of FIVR in reminiscence interventions, its usability and acceptability, and its effectiveness in assisting the intervention to achieve optimal outcomes.

METHODS

We followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) approach for scoping reviews. The PubMed, PsycINFO, Embase, CINAHL, Web of Science, ACM, and IEEE Xplore electronic databases were used for the search. We included peer-reviewed studies that used FIVR as an assistive tool for reminiscence interventions; were published between January 1, 2000, and August 1, 2022; reported empirical research; involved older adults as participants; and addressed health- and behavior-related outcomes or the feasibility and usability of FIVR. We used Endnote X9 to organize the search results and Microsoft Excel for data extraction and synthesis.

RESULTS

Of the 806 articles collected from the databases and other resources, 11 were identified. Most of the studies involved participants aged between 70 and 90 years. Only 1 study did not involve those with cognitive impairments, whereas 3 specifically targeted people living with dementia. The results indicated that FIVR reminiscence interventions enhanced engagement and reduced fatigue. Although some studies have observed positive effects on anxiety, apathy, depression, cognitive functions, and caregiver burden reduction, these findings were inconsistent across other research. In addition, FIVR showed overall usability and acceptability with manageable side effects among older adults across various health conditions during reminiscence sessions. However, 1 study reported adverse feelings among participants, triggered by unpleasant memories evoked by the virtual reality content.

CONCLUSIONS

The role of FIVR in reminiscence interventions remains nascent, with limited studies evaluating its impacts on older adults. Many of the reviewed studies had notable limitations: small sample sizes, absence of rigorous research design, limited assessment of long-term effects, lack of measures for health and behavior outcomes, and quality of life. Beyond these limitations, this review identified a list of future research directions in 6 categories. On the basis of the review findings, we provide practical recommendations to enhance FIVR reminiscence interventions, covering topics such as virtual reality content, device choice, intervention types, and the role and responsibility of facilitators.

Study protocol for ELders AT Ease (ELATE): a cluster randomised controlled trial of cognitive behaviour therapy to reduce depressive symptoms in aged care residents

BACKGROUND

This protocol describes a study of the effectiveness of cognitive behaviour therapy (CBT) for reducing depressive symptoms in older adults living in residential aged care (RAC) facilities in Australia. Depressive symptoms are highly prevalent in this population, yet the benefits of CBT for reducing such symptoms in RAC facilities have not been widely investigated. Elders at Ease (ELATE) is a 16-session CBT intervention designed for implementation in RAC facilities. The intervention includes cognitive, behavioural and reminiscence strategies and is delivered by mental health trainees (MHTs) in collaboration with RAC facility staff and residents' family.

METHODS AND ANALYSIS

ELATE will be evaluated using a cluster randomised trial comparing outcomes for residents who participate in the intervention with those living in usual care control facilities. The participants are RAC residents aged 65 years or above, with depressive symptoms (Patient Health Questionnaire-2 ≥ 3) and normal cognition or mild cognitive impairment (Standardised Mini Mental Status Examination ≥ 21). They are assessed at four time points: baseline prior to randomisation (T1), mid-treatment (T2; 2.5 months post randomisation), post-treatment (T3; 5 months post-randomisation) and 3-month follow-up (T4; 8 months post randomisation). The primary outcome is change in depressive symptoms between T1 and T3. Secondary outcomes are depressive symptoms at T4, anxiety, suicide ideation, sleep problems, quality of life, staff and family knowledge of late-life depression, stress levels and efficacy in caring for residents, and MHT levels of geropsychology competencies. Residents receiving the intervention are hypothesised to report a greater decrease in depressive symptoms between T1 and T3 compared to residents receiving usual care. The primary analysis is a regression, clustered over site to account for correlated readings, and independent variables are condition and depressive symptoms at T1. A cost-utility analysis is also undertaken.

DISCUSSION

ELATE is a comprehensive CBT intervention for reducing depressive symptoms in RAC residents. It is designed to be implemented in collaboration with facility staff and residents' families, individually tailored to residents with normal cognition to mild cognitive impairment and delivered by trainee therapists. ELATE offers a model that may be widely applicable across the RAC sector.

Older adults' experiences of social isolation and loneliness: Can virtual touring increase social connectedness? A pilot study

The present pilot study explored the research aim of understanding how independent-living older adults experience social isolation and loneliness and whether virtual tour digital technology can increase social connectedness (N = 10). Through triangulation of interviews, experiences, and feedback, this study contributes to the knowledge base on the well-being of our ageing populations and how digital technologies, specifically virtual tourism, can aid in this process. The key findings reveal that the participants in our study were moderately lonely but were open to embracing more digital technology, sharing how it is instrumental in facilitating social connection and life administration. Participating in virtual tour experiences was well accepted as participants expressed enjoyment, nostalgia, and interest in future use. However, its contribution to increasing social connections needs to be clarified and requires further investigation. Several future research and education directions are provided.

Machine learning approach for early onset dementia neurobiomarker using EEG network topology features

Introduction

Modern neurotechnology research employing state-of-the-art machine learning algorithms within the so-called "AI for social good" domain contributes to improving the well-being of individuals with a disability. Using digital health technologies, home-based self-diagnostics, or cognitive decline managing approaches with neuro-biomarker feedback may be helpful for older adults to remain independent and improve their wellbeing. We report research results on early-onset dementia neuro-biomarkers to scrutinize cognitive-behavioral intervention management and digital non-pharmacological therapies.

Methods

We present an empirical task in the EEG-based passive brain-computer interface application framework to assess working memory decline for forecasting a mild cognitive impairment. The EEG responses are analyzed in a framework of a network neuroscience technique applied to EEG time series for evaluation and to confirm the initial hypothesis of possible ML application modeling mild cognitive impairment prediction.

Results

We report findings from a pilot study group in Poland for a cognitive decline prediction. We utilize two emotional working memory tasks by analyzing EEG responses to facial emotions reproduced in short videos. A reminiscent interior image oddball task is also employed to validate the proposed methodology further.

Discussion

The proposed three experimental tasks in the current pilot study showcase the critical utilization of artificial intelligence for early-onset dementia prognosis in older adults.

Effects of cognitive stimulation therapy on patients with dementia: An umbrella review of systematic reviews and meta-analyses

BACKGROUND

Dementia is characterized by significant cognitive decline that results in disturbance of daily activities. Increasing number of meta-analyses has examined the efficacy of cognitive stimulation therapy (CST) for dementia. However, there is a lack of comprehensive reports that specifically discuss the strength of evidence to support CST for dementia.

PURPOSE

This study aimed to summarize evidence regarding the efficacy of CST on people with dementia.

DESIGN

Umbrella review of systematic reviews and meta-analyses.

METHODS

We searched Cochrane Library, PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Data, China Biology Medicine disc (CBMdisc), and VIP databases from inception to December 31, 2022. The methodological quality of the identified studies was assessed using A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR 2). Studies scoring 9-12 (moderate quality) points or higher were further analyzed using Grades of Recommendations Assessment, Development and Evaluation (GRADE) principles.

RESULTS

A total of 14 systematic reviews and meta-analyses were included in the umbrella review. The methodological quality of most included reviews was rated as moderate according to AMSTAR 2 rating system. In these studies, we summarized the characteristics of the content, providers, frequency, period and setting of CST, and examined eight health outcomes related to CST, including cognition, depression, behavioral symptoms, quality of life (QoL), activities of daily living (ADL), language and communication, anxiety, and memory. Eleven studies with low to high rating of overall confidence (OC) consistently reported that CST could significantly improve cognition of people with dementia, including high-quality supporting evidence. However, the effect of CST on other health outcomes for people with dementia (e.g., depression, behavioral symptoms, QoL, ADL) is inconsistent, with low- to moderate-quality evidence ratings. Compared with the above results, few studies have reported the effects of CST on communication, anxiety, and memory for people with dementia.

CONCLUSIONS

In the future, the design and reporting of systematic reviews and meta-analyses should incorporate high-quality research metrics in accordance with AMSTAR 2 criteria. The current review supports CST as an effective treatment for improving cognitive function in patients with dementia. Multi-component interventions are more effective than single-component interventions and need to be delivered regularly.

REGISTRATION

The protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO) database (CRD42022364259).

Effects of aerobic exercise on global cognitive function and sleep in older adults with mild cognitive impairment: A systematic review and meta-analysis

We conducted a systematic review and meta-analysis to determine the integrated effect of aerobic exercise on cognitive function and sleep in older adults with mild cognitive impairment (MCI) and to optimize exercise methods for improving cognitive function. We searched multiple databases from January 1, 2011, to August 31, 2022, and analyzed 11 studies. Global cognitive function in older adults with MCI undergoing aerobic exercise training was significantly improved (standardized mean difference [SMD]=0.76, 95% confidence interval [CI]:0.37, 1.14), while sleep improvement was not significant (SMD= -2.07 [95% CI: -6.76, 2.62]). In the moderator analysis, aerobic exercise types with cognitive factors, exercise time of 30-50 min per session, and exercise frequency of 5-7 times per week had statistically significant effects on cognitive function improvement. However, meta-regression identified only exercise frequency as a significant moderator of the mean effect size of cognitive function.

The Efficacy of Reminiscence Therapy in Cancer-Related Symptom Management: A Systematic Review and Meta-Analysis

BACKGROUND

At present, simple reminiscence has been widely used in the field of neurocognitive disorders, life review/life review therapy has been widely used in the field of cancer, and both simple reminiscence and life review/life review therapy are suitable for psychological disorders such as depression and anxiety. However, the efficacy of reminiscence in treating cancer-related symptom has not been fully assessed.

OBJECTIVES

To evaluate the effect of reminiscence therapy (RT) on relieving cancer-related symptoms such as anxiety and depression in cancer survivals.

METHODS

China National Knowledge Infrastructure (CNKI), VIP database, Wanfang Data Knowledge Service Platform, China Biomedical Database, PubMed, Cochrane Library, Embase, EBSCO, Scopus, and Ovid databases were searched. To collect clinical randomized controlled trials (RCT) on RT and cancer-related studies published from the establishment of the database to October 05, 2021. Two researchers independently evaluated the articles that met the inclusion criteria, meta-analysis was performed using RevMan5.4 software.

RESULTS

A total of 20 RCTs published in 2010 to 2021 were included, with a total of 1853 cancer patients. Meta-analysis results showed that the anxiety scale (HADS-A and HAMA and SAS) and depression scale (HADS-D and HAMD and SDS) scores of the RT group were significantly lower than those of the control group (HADS-A: P = .0002; HAMA: P < .00001; SAS: P = .0010; HADS-D: P = .01; HAMD: P < .00001; SDS: P = .0001). Meta-analysis results showed that RT can improve overall quality of life of cancer patients of RT group to a certain extent hope (P < .00001). Meta-analysis results showed that the scores on the hope and dignity were significantly increased, and the difference were statistically significant (P < .001).

CONCLUSION

This review indicates that RT has significant efficacy on cancer-related symptoms such as anxiety and depression. RT for cancer survivals can effectively improve quality of life, self-hope, and self-esteem. The findings of this meta-analysis can provide direction for future symptom management research.

Effectiveness of reminiscence therapy interventions for older people: Evidence mapping and qualitative evaluation

WHAT IS KNOWN ON THE SUBJECT?: Reminiscence therapy is a common psychosocial intervention in mental health nursing. Numerous secondary studies have explored the effects of reminiscence therapy interventions in older adults, and while the effects are significant, conflicting results remain. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: To date, research on reminiscence therapy has examined different disorders in isolation from one another. By illustrating the evidence gaps between studies, this paper highlights the need for a new evidence-based summary overview of reminiscence therapy research. The results suggest that reminiscence therapy can be beneficial to the improvement of mental health and quality of life for older people. However, we found that the secondary studies were not of high quality and that further high-quality literature supporting the evidence is still needed. WHAT ARE THE IMPLICATION FOR PRACTICE?: Reminiscence therapy may be considered a useful non-pharmacological intervention for older people with mental and psychological problems. However, there is a lack of normative guidelines for reminiscence therapy in terms of intervention time, frequency, and form. The development of a global standard protocol for the application of reminiscence therapy may be necessary for future randomized controlled trials (RCTs).

ABSTRACT

INTRODUCTION: Reminiscence therapy is an alternative to pharmaceutical intervention provided during long-term care, especially for older people with mental and psychological problems. However, the effects of reminiscence therapy remain inconclusive.

AIM

The present study aimed to systematically identify, synthesize and describe the research evidence and quality of systematic reviews (SRs) related to reminiscence interventions for older people through an evidence-mapping approach.

METHODS

Commonly used English and Chinese databases, including PubMed, EMBASE, The Cochrane Library, Web of Science, CNKI, WANFANG, VIP and SinoMed, were searched from inception till 31 March 2022. The study type was restricted to SRs with or without meta-analysis. The methodological quality of the included SRs was assessed by A Measurement Tool to Assess Systematic Reviews (AMSTAR-2). The Microsoft Excel 2019 tool was used for data extraction and coding, and bubble charts were used to synthesize information on the study population, intervention category, original study sample size and classification of findings.

RESULTS

A total of 28 SRs were enrolled, including 514 original studies, 91.4% of which were randomized controlled trials. The main participants of the study were depressed older people (7 publications), older people with dementia (10 publications) and ordinary older people (8 publications). The findings of 26 (92.8%) publications were categorized as either "beneficial" or "potentially beneficial." The primary outcome indicators of the effectiveness of the reminiscence intervention for older people are mental and psychological problems (especially depressive symptoms and cognitive functioning), quality of life and categories of positive psychology (e.g., life satisfaction, happiness and self-esteem). The main factors influencing the intervention effect were the intervention period, residential setting, intervention format (group/individual) and intervention intensity. The intervention settings/contexts were mainly community and long-term care facilities. However, the methodological quality of 27 (96.4%) of the SRs was scored as either "Low" or "Critically Low."

DISCUSSION

Reminiscence therapy has been used to study the mental health and quality of life of older people in various conditions, with significant results. However, due to the limited evidence included in the studies and the low methodological quality, there is still a need to focus on the issue of effectiveness and evidence gaps for different interventions in the field of recall in the future, in addition to efforts to improve the methodological quality and standardize the reporting process for the evaluation of reminiscence intervention systems.

IMPLICATIONS FOR PRACTICE

Reminiscence therapy may be considered a useful non-pharmacological intervention for older people with mental and psychological problems. A standard protocol for reminiscence therapy may be necessary for future studies.

Effects of Reminiscence Therapy on Cognition, Depression and Quality of Life in Elderly People with Alzheimer’s Disease: A Systematic Review of Randomized Controlled Trials

Background: Patients with Alzheimer’s disease (AD) present with cognitive function deterioration, neuropsychiatric symptoms (NPS)—especially depression—and low quality of life (QoL). Management of AD remains difficult, especially in the elderly. Reminiscence therapy (RT) is a well-known cognitive rehabilitation intervention that can be adopted in nursing and residential care homes to restore autobiographical memory, ameliorate NPS, and improve the QoL of people with dementia. However, the evidence-based efficacy of RT for elderly patients with AD remains to be determined. Methods: Here, we synthesized findings of randomized controlled trials (RCTs) exploring the effects of RT on cognition, depression, and QoL in elderly people with AD, according to the most recent PRISMA statement. We searched for RCTs in PubMed, Web of Science, and Cochrane Central Register of Controlled Trials, and in trial registries (i.e., clinicaltrials.gov and International Clinical Trials Registry Platform of the World Health Organization). Two review authors extracted data of interest, with cognition, depression, and QoL measures as outcomes. Results: A total of five articles were included in the final analysis. Findings globally showed that RT, both administered in individual or group sessions at least once a week for 30–35 min over a period of 12 weeks, is effective in supporting global cognition, ameliorating depression, and improving specific aspects of the QoL in elderly people with AD. Conclusions: RT has the potential to be a routine non-pharmacological therapy for elderly people with AD, thanks to its wider effects on the individual in terms of cognitive vitality and emotional status promotion, with positive implications for patient’s daily life. Despite such evidences, caution should be used in findings’ generalizability in relation to the paucity of existing RCTs with long-term follow-up.

The Long-term Effects of Immersive Virtual Reality Reminiscence in People With Dementia: Longitudinal Observational Study

Background

Novel nonpharmacological therapies are being developed to prevent cognitive decline and reduce behavioral and psychological symptoms in patients with dementia. Virtual reality (VR) reminiscence was reported to improve anxiety, apathy, and cognitive function immediately after intervention in individuals at residential aged care facilities. However, its effect on elderly patients with dementia and how long this effect could last remain unknown.

Objective

The aim of this paper is to investigate the effect of immersive VR reminiscence in people with dementia both immediately after and 3-6 months after intervention.

Methods

A pilot study was conducted in 2 dementia care units. VR reminiscence therapy sessions were conducted twice per week for a 3-month period. Cognitive function, global status, depressive symptoms, and caregiver burden were assessed before and immediately after VR intervention in 20 participants. Subsequently, 7 participants were reassessed 3-6 months after the VR intervention. Wilcoxon sign-rank test was used for statistical comparisons of the changes.

Results

There were no significant changes in cognitive function, global status, and caregiver burden immediately after the VR intervention, but there was a significant reduction in depressive symptoms (P=.008). Moreover, compared with the cognitive function immediately after VR, it kept declining 3-6 months after.

Conclusions

Immersive VR reminiscence can improve mood and preserve cognitive function in elderly patients with dementia during the period of the intervention. Studies using a control group and comparing the use of VR with traditional forms of reminiscence should be conducted in the future to confirm and expand on these findings.
