The Right to Rehabilitation for People With Dementia: A Codesign Approach to Barriers and Solutions

INTRODUCTION

People with dementia of all ages have a human right to equal access to quality health care. Despite evidence regarding its effectiveness, many people living with dementia are unable to access rehabilitation for promoting function and quality of life. Conducted in Australia, this study was designed to (1) explore barriers to access to dementia rehabilitation and (2) identify solutions that improve access to rehabilitation.

METHODS

People living with dementia (n = 5) and care partners (n = 8) and health professionals (n = 13) were recruited nationally. Experience-based codesign across three virtual workshops was used to understand barriers and design solutions to improve access to rehabilitation treatments. Socio-ecological analyses, using the Levesque Access to Health care framework, were applied to findings regarding barriers and to aid selection of solutions.

RESULTS

There was high attendance (92.3%) across the three workshops. Barriers were identified at a user level (including lack of knowledge, transport, cost and difficulty navigating the health, aged care and disability sectors) and health service level (including health professional low dementia knowledge and negative attitudes, inequitable funding models and non-existent or fragmented services). Solutions focused on widespread dementia education and training, including ensuring that people with dementia and their care partners know about rehabilitation therapies and that health professionals, aged care and disability co-ordinators know how to refer to and deliver rehabilitation interventions. Dementia care navigators, changes to Australia's public funding models and specific dementia rehabilitation programmes were also recommended.

CONCLUSIONS

Barriers to accessing rehabilitation for people with dementia exist at multiple levels and will require a whole-community and systems approach to ensure change.

PATIENT OR PUBLIC CONTRIBUTION

People with living experience (preferred term by those involved) were involved at two levels within this research. A Chief Investigator living with dementia was involved in the design of the study and writing of the manuscript. People with living experience, care partners and service providers were participants in the codesign process to identify barriers and design potential solutions.

Association Between the Average Number of In-Network Hospitals and Medical Counseling for Cognitive Impairment in South Korea

OBJECTIVES

Mild cognitive impairment, a pressing concern in the face of a rapidly growing global older adult population, necessitates effective management strategies focused on sustained symptom relief and preventing deterioration. Community Dementia Care Centers, in partnership with in-network hospitals, aim to provide support for preventing mild cognitive impairment and dementia. Medical counseling, influenced by in-network hospitals, is crucial for tailoring interventions to the cognitive abilities and specific needs of each older adult, protecting against dementia. Disparities in the number of in-network hospitals and healthcare infrastructure can contribute to uneven access to dementia care, thereby creating health inequities.

DESIGN

Cross-sectional study.

SETTING AND PARTICIPANTS

Using data from the Korea Community Health Survey (2018-2019), this study focused on South Korean individuals aged 60 and older in 17 metropolitan areas and provinces.

METHODS

A multiple regression analysis was used to examine the relationship between the average number of in-network hospitals and medical counseling experience, considering sociodemographic factors and related variables.

RESULTS

Areas with a higher average number of in-network hospitals exhibited increased medical counseling experiences. Significantly higher odds for medical counseling experience were observed in regions with "more than 5 hospitals" (1.36; 95% CI, 1.20-1.54; P = .000) than those with "3 or fewer hospitals."

CONCLUSIONS AND IMPLICATIONS

This study underscores the importance of infrastructure, particularly collaborative hospitals that support Community Dementia Care Centers, in influencing individual dementia management and prevention. These findings highlight the significance of dementia prevention and management infrastructures, emphasizing the need for practical assistance, particularly in regions crucial for achieving health equity.

The role and impact of therapeutic counselling on the emotional experience of adults living with dementia: A systematic review

Introduction There is limited psychological support available to help people living with dementia to deal with the emotional consequences of their condition. Anxiety and depression are commonly experienced in this population, yet the use of counselling and psychotherapeutic interventions is not well documented. Aim This systematic review sought to understand the current knowledge on the role and impact of therapeutic counselling on the emotional experience of adults living with dementia. Methods Qualitative and quantitative research designs were accepted for review. A comprehensive search of the main biomedical, nursing and other specialist databases was performed to access articles published between 2015 and 2022. Trial registers and academic journals were also searched. 43 original studies were included: qualitative (n = 15); RCTs (n = 9); other designs (n = 19); plus eight systematic reviews. Results The majority of studies were conducted in Europe, the United Kingdom in particular, although a range of countries from across the globe were represented. The combined evidence from the different study designs suggest a range of ways that people living with different stages of dementia can participate in, and gain emotional benefit from, therapeutic counselling. Key themes identified: (1) The emotional and well-being benefits of therapeutic counselling; (2) No one size fits all - relational and tailored approaches driven by person-centred values; (3) Training, supervision and building community for counsellors; (4) Involvement of people with dementia in therapeutic interventions. Conclusions Our findings from this systematic review show that different therapeutic approaches have been tested with people at different stages of a dementia diagnosis. The results suggest the value of therapeutic counselling as a supportive medium to help with the processing and coping of difficult emotions and feelings across the trajectory of a dementia illness.

Cognitive and psychological characteristics in patients with Cerebral Amyloid Angiopathy: a literature review

AIM

To review the current data on cognitive and psychological characteristics of patients with CAA and on the instruments used for their evaluation.

METHODS

A systematic search was performed in Embase, Scopus and PubMed with terms related to "cerebral amyloid angiopathy", "neuropsychological measures" and "patient-reported outcome measures" from January 2001 to December 2021.

RESULTS

Out of 2851 records, 18 articles were selected. The cognitive evaluation was present in all of which, while the psychological one only in five articles. The MMSE (Mini Mental State Examination), TMT (Trail Making Test), fluency test, verbal learning test, digit span, digit symbol and Rey figure tests were the most used cognitive tests, while executive function, memory, processing speed, visuospatial function, attention and language were the most frequent impaired cognitive functions. Depression was the most considered psychological factor usually measured with BDI (Beck Depression Inventory) and GDS (Geriatric Depression Scale).

CONCLUSIONS

The results of this study might be used in clinical practice as a guide to choose cognitive and psychological instruments and integrate them in the clinical evaluation. The results might also be used in the research field for studies investigating the impact of cognitive and psychological variables on the disease course and for consensus studies aimed at define a standardized evaluation of these aspects.

Introduction to Large Language Models (LLMs) for dementia care and research

Introduction

Dementia is a progressive neurodegenerative disorder that affects cognitive abilities including memory, reasoning, and communication skills, leading to gradual decline in daily activities and social engagement. In light of the recent advent of Large Language Models (LLMs) such as ChatGPT, this paper aims to thoroughly analyse their potential applications and usefulness in dementia care and research.

Method

To this end, we offer an introduction into LLMs, outlining the key features, capabilities, limitations, potential risks, and practical considerations for deployment as easy-to-use software (e.g., smartphone apps). We then explore various domains related to dementia, identifying opportunities for LLMs to enhance understanding, diagnostics, and treatment, with a broader emphasis on improving patient care. For each domain, the specific contributions of LLMs are examined, such as their ability to engage users in meaningful conversations, deliver personalized support, and offer cognitive enrichment. Potential benefits encompass improved social interaction, enhanced cognitive functioning, increased emotional well-being, and reduced caregiver burden. The deployment of LLMs in caregiving frameworks also raises a number of concerns and considerations. These include privacy and safety concerns, the need for empirical validation, user-centered design, adaptation to the user's unique needs, and the integration of multimodal inputs to create more immersive and personalized experiences. Additionally, ethical guidelines and privacy protocols must be established to ensure responsible and ethical deployment of LLMs.

Results

We report the results on a questionnaire filled in by people with dementia (PwD) and their supporters wherein we surveyed the usefulness of different application scenarios of LLMs as well as the features that LLM-powered apps should have. Both PwD and supporters were largely positive regarding the prospect of LLMs in care, although concerns were raised regarding bias, data privacy and transparency.

Discussion

Overall, this review corroborates the promising utilization of LLMs to positively impact dementia care by boosting cognitive abilities, enriching social interaction, and supporting caregivers. The findings underscore the importance of further research and development in this field to fully harness the benefits of LLMs and maximize their potential for improving the lives of individuals living with dementia.

Combined exercise and cognitive interventions for adults with mild cognitive impairment and dementia: A systematic review and network meta-analysis

BACKGROUND

Exercise and cognitive interventions are beneficial for adults with preclinical and clinical dementia, but it is unclear whether the combination of these two components could generate synergistic benefits and what intervention designs would optimize this effect.

OBJECTIVES

This review aims to compare the effects of combined exercise and cognitive interventions on cognitive, psychological, functional outcomes, and health-related quality of life with the corresponding single approach and control groups in adults with mild cognitive impairment and dementia. It also aims to identify the optimal intervention design and factors affecting treatment effects.

METHODS

A comprehensive search was conducted in ten databases from inception to 23rd November 2022. The methodological quality of studies was evaluated by the Cochrane risk of bias tool. Pairwise meta-analyses were performed to assess the effects of combined interventions relative to the single type of intervention and control groups, with further subgroup analysis to explore the factors affecting treatment effects. Network meta-analyses were used to identify the optimal intervention components.

RESULTS

Twenty-nine randomized controlled trials involving 2910 participants were included. The results of pairwise meta-analyses indicated that combined interventions were superior to exercise in improving response inhibition, working memory, and delayed recall, but were not superior to cognitive interventions in all outcomes. Combined interventions were superior to active/passive controls in improving global cognition, response inhibition, immediate recall, delayed recall, category fluency, processing speed, and visuospatial ability. Influences of the clinical severity of dementia (mild cognitive impairment vs dementia), combination format (sequential vs simultaneous combination), mode of delivery (group-based vs individual-based vs mixed), training duration (short: ≤12 weeks vs medium: 13-24 weeks vs long: >24 weeks), and types of control (active vs passive control) were not detected. The network meta-analysis results indicated that the optimal intervention components varied across different outcomes, with multimodal exercise combining cognitive training demonstrated the greatest effects among all other combined or single component interventions in improving global cognition.

CONCLUSIONS

This review suggests the advantage of combined interventions over exercise with comparable effects when compared with cognitive interventions in the population with mild cognitive impairment and dementia. Full scale multi-arm randomized controlled trials to compare the effects of combined interventions with cognitive interventions are warranted.

Effect of internet-based vs. in-person multimodal interventions on patients with mild to moderate Alzheimer's disease: a randomized, cross-over, open-label trial

Objective

We aimed to investigate the effect of internet-based and in-person cognitive interventions on cognition, mood, and activities of daily living (ADL) on patients with mild to moderate Alzheimer's disease (AD) and examine whether internet-based intervention is as effective as the in-person intervention.

Methods

We recruited 52 patients with probable mild AD, of whom 42 completed the trial. We randomly divided participants into intervention and control groups at a 1:1 ratio and statistically compared the neuropsychological test results of the two groups. In addition, patients in the intervention group were randomly assigned to a 4 weeks internet-based or in-person intervention, with subsequent crossover to the other group for 4 weeks. We statistically analyzed and compared the neuropsychological test scores between internet-based and in-person interventions.

Results

Compared with the control group, the intervention group (internet-based and in-person) showed significantly improved profile in cognition (p < 0.001), depression (p < 0.001), anxiety (p < 0.001) and ADL (p < 0.001). In addition, the effect of the internet-based intervention on cognition (p = 0.918) and depression (p = 0.282) was not significantly different from that of the in-person intervention. However, in the Beck anxiety inventory (p = 0.009) and Seoul instrumental activity of daily living (p = 0.023), in-person intervention was more effective than internet-based intervention.

Conclusion

This study suggests that both types of cognitive intervention (in-person and internet-based) may be viable supplementary treatments along with approved pharmacological therapy. In terms of anxiety and ADL, the effect of the in-person interventions may be more effective than the-internet based interventions.

A single-blind, parallel-group randomised trial of a Technology-assisted and remotely delivered Cognitive Behavioural Therapy intervention (Tech-CBT) versus usual care to reduce anxiety in people with mild cognitive impairment and dementia: study protocol for a randomised trial

BACKGROUND

Anxiety is commonly experienced by people living with mild cognitive impairment (MCI) and dementia. Whilst there is strong evidence for late-life anxiety treatment using cognitive behavioural therapy (CBT) and delivery via telehealth, there is little evidence for the remote delivery of psychological treatment for anxiety in people living with MCI and dementia. This paper reports the protocol for the Tech-CBT study which aims to investigate the efficacy, cost-effectiveness, usability and acceptability of a technology-assisted and remotely delivered CBT intervention to enhance delivery of anxiety treatment for people living with MCI and dementia of any aetiology.

METHODS

A hybrid II single-blind, parallel-group randomised trial of a Tech-CBT intervention (n = 35) versus usual care (n = 35), with in-built mixed methods process and economic evaluations to inform future scale-up and implementation into clinical practice. The intervention (i) consists of six weekly sessions delivered by postgraduate psychology trainees via telehealth video-conferencing, (ii) incorporates voice assistant app technology for home-based practice, and (iii) utilises a purpose-built digital platform, My Anxiety Care. The primary outcome is change in anxiety as measured by the Rating Anxiety in Dementia scale. Secondary outcomes include change in quality of life and depression, and outcomes for carers. The process evaluation will be guided by evaluation frameworks. Qualitative interviews will be conducted with a purposive sample of participants (n = 10) and carers (n = 10), to evaluate acceptability and feasibility, as well as factors influencing participation and adherence. Interviews will also be conducted with therapists (n = 18) and wider stakeholders (n = 18), to explore contextual factors and barriers/facilitators to future implementation and scalability. A cost-utility analysis will be undertaken to determine the cost-effectiveness of Tech-CBT compared to usual care.

DISCUSSION

This is the first trial to evaluate a novel technology-assisted CBT intervention to reduce anxiety in people living with MCI and dementia. Other potential benefits include improved quality of life for people with cognitive impairment and their care partners, improved access to psychological treatment regardless of geographical location, and upskilling of the psychological workforce in anxiety treatment for people living with MCI and dementia.

TRIAL REGISTRATION

This trial has been prospectively registered with ClinicalTrials.gov: NCT05528302 [September 2, 2022].

Brief App-Based Cognitive Behavioral Therapy for Anxiety Symptoms in Psychiatric Inpatients: Feasibility Randomized Controlled Trial

Background

Psychiatric inpatients often have limited access to psychotherapeutic education or skills for managing anxiety, a common transdiagnostic concern in severe and acute mental illness. COVID-19–related restrictions further limited access to therapy groups on inpatient psychiatric units. App-based interventions may improve access, but evidence supporting the feasibility of their use, acceptability, and effectiveness in psychiatric inpatient settings is limited. MindShift CBT is a free app based on cognitive behavioral therapy principles with evidence for alleviating anxiety symptoms in the outpatient setting.

Objective

We aimed to recruit 24 participants from an acute general psychiatric inpatient ward to a 1-month randomized control study assessing the feasibility and acceptability of providing patients with severe and acute mental illness access to the MindShift CBT app for help with managing anxiety symptoms.

Methods

Recruitment, data collection, analysis, and interpretation were completed collaboratively by clinician and peer researchers. Inpatients were randomized to two conditions: treatment as usual (TAU) versus TAU plus use of the MindShift CBT app over 6 days. We collected demographic and quantitative data on acceptability and usability of the intervention. Symptoms of depression, anxiety, and psychological distress were measured in pre- and poststudy surveys for preliminary signals of efficacy. We conducted individual semistructured interviews with participants in the MindShift CBT app group at the end of their trial period, which were interpreted using a standardized protocol for thematic analysis.

Results

Over 4 weeks, 33 inpatients were referred to the study, 24 consented to participate, 20 were randomized, and 11 completed the study. Of the 9 randomized participants who did not complete the study, 7 were withdrawn because they were discharged or transferred prior to study completion, with a similar distribution among both conditions. Among the enrolled patients, 65% (13/20) were admitted for a psychotic disorder and no patient was admitted primarily for an anxiety disorder. The average length of stay was 20 days (SD 4.4; range 3-21) and 35% (7/20) of patients were involuntarily admitted to hospital. Small sample sizes limited accurate interpretation of the efficacy data. Themes emerging from qualitative interviews included acceptability and usability of the app, and patient agency associated with voluntary participation in research while admitted to hospital.

Conclusions

Our study benefitted from collaboration between peer and clinician researchers. Due to rapid patient turnover in the acute inpatient setting, additional flexibility in recruitment and enrollment is needed to determine the efficacy of using app-based psychotherapy on an acute psychiatric ward. Despite the limited sample size, our study suggests that similar interventions may be feasible and acceptable for acutely unwell inpatients. Further study is needed to compare the efficacy of psychotherapeutic apps with existing standards of care in this setting.

Hypnosis Intervention for Couples Confronted with Alzheimer’s Disease: Promising Results of a First Exploratory Study

Background: Dementia has a negative impact on the quality of life of the person with dementia and their spouse caregivers, as well as on the couple’s relationship, which can lead to high levels of distress for both partners. Hypnosis has been shown to be effective in managing distress and increasing the quality of the relationship. Objective: The aim was to develop a standardized hypnosis intervention for couples confronted with Alzheimer’s disease and evaluate its feasibility, acceptability, and helpfulness in managing the distress of both partners and increasing the quality of the relationship. Methods: In a single-arm study, sixteen couples received the 8-week intervention. Qualitative and quantitative assessments were conducted pre- and post-intervention as well as three months after. Results: 88.9% of couples (n = 16) of the final sample (n = 18) completed the intervention. Despite the negative representations of hypnosis, several factors led couples to accept to participate in this study: positive expectations, professional endorsement, medical application, non-drug approach, home-based, free, flexible, and couple-based intervention. The results showed a significant decrease in distress for both partners. These effects were maintained three months after the intervention. Couples felt more relaxed, had fewer negative emotions, accepted difficulties more easily, were more patient, and reported better communication and more affection in the relationship. Conclusion: Overall, this pilot study shows the feasibility and acceptability of hypnosis with couples confronted with Alzheimer’s disease. Although measures of the preliminary pre- and post-intervention effects are encouraging, confirmatory testing with a randomized controlled trial is needed.

Nonpharmacological approaches reduce symptoms of depression in dementia: A systematic review and meta-analysis

BACKGROUND

Depression is a common psychological symptom associated with dementia. Pharmacological approaches are often used despite two large negative trials of efficacy. This meta-analysis examines nonpharmacological (i.e., psychosocial) approaches for symptoms of depression in people living with dementia and reports statistical and clinical significance.

METHODS

Relevant studies published between 2012 and 2020 were sourced by searching electronic databases: MEDLINE, EMBASE, PsychINFO, Social Work Abstracts and the Cochrane Central Register of Controlled Trials. Studies were assessed for methodological quality. Random-effects meta-analysis was performed to calculate a pooled effect size (ES) and 95% confidence intervals (CI).

RESULTS

Overall, 37 nonpharmacological studies were identified including 2,636 participants. The mean quality rating was high (12/14, SD=1.4). Meta-analysis revealed that nonpharmacological approaches were significantly associated with reduced symptoms of depression with a medium effect size (ES=-0.53, 95%CI [-0.72, -0.33], p < 0.0001). There was considerable heterogeneity between studies. Meta-regression revealed this was not driven by intervention type or setting (residential versus community).

CONCLUSIONS

Nonpharmacological approaches such as reminiscence, cognitive stimulation/ rehabilitation, therapeutic, music-based approaches and education/ training, have the potential to reduce symptoms of depression in dementia.

A systematic review of neural, cognitive, and clinical studies of anger and aggression

Anger and aggression have large impact on people's safety and the society at large. In order to provide an intervention to minimise aggressive behaviours, it is important to understand the neural and cognitive aspects of anger and aggression. In this systematic review, we investigate the cognitive and neural aspects of anger-related processes, including anger-related behaviours and anger reduction. Using this information, we then review prior existing methods on the treatment of anger-related disorders as well as anger management, including mindfulness and cognitive behavioural therapy. At the cognitive level, our review that anger is associated with excessive attention to anger-related stimuli and impulsivity. At the neural level, anger is associated with abnormal functioning of the amygdala and ventromedial prefrontal cortex. In conclusions, based on cognitive and neural studies, we here argue that mindfulness based cognitive behavioural therapy may be better at reducing anger and aggression than other behavioural treatments, such as cognitive behavioural therapy or mindfulness alone. We provide key information on future research work and best ways to manage anger and reduce aggression. Importantly, future research should investigate how anger related behaviours is acquired and how stress impacts the development of anger.

Cognitive Behavioral Therapy for Mood and Insomnia in Persons With Dementia: A Systematic Review

BACKGROUND

Cognitive behavioral therapy (CBT) is a goal-oriented intervention that aims to improve detrimental emotional or behavioral distress by modifying individuals' thought processes. This review evaluates the efficacy and specific adaptations of CBT in persons with mild cognitive impairment and dementia.

METHODS

A literature search of PubMed, Embase, and PsycINFO was conducted up to March 2020. Study quality was assessed using the Cochrane risk of bias criteria.

RESULTS

Twelve publications were identified. Seven of the studies demonstrated CBT efficacy to improve depression, anxiety, and/or quality of life. One study's positive postintervention outcome became insignificant with longer term follow up. Two of the studies improved sleep outcomes. Four studies integrated caregivers into intervention delivery. Three studies utilized content, memory, and adherence adaptations aimed to improve intervention efficacy. Two studies included adaptations to address caregiver burden and depression.

CONCLUSION

There is strong evidence to suggest that CBT is associated with improvements in anxiety, depression, and quality of life in persons with mild cognitive impairment and dementia. CBT showed a reduction in insomnia and improvements in sleep quality. However, there is insufficient evidence to draw conclusions on the effects of CBT on insomnia. These results suggest that further investigation into insomnia outcomes is needed.

Dismantling internet-based cognitive behavioral therapy for tinnitus. The contribution of applied relaxation: A randomized controlled trial

BACKGROUND

Internet-based cognitive behavioral therapy (ICBT) for tinnitus is an evidence-based intervention. The components of ICBT for tinnitus have, however, not been dismantled and thus the effectiveness of the different therapeutic components is unknown. It is, furthermore, not known if heterogeneous tinnitus subgroups respond differently to ICBT.

AIMS

This dismantling study aimed to explore the contribution of applied relaxation within ICBT for reducing tinnitus distress and comorbidities associated with tinnitus. A secondary aim was to assess whether outcomes varied for three tinnitus subgroups, namely those with significant tinnitus severity, those with low tinnitus severity, and those with significant depression.

METHODS

A parallel randomized controlled trial design (n = 126) was used to compare audiologist-guided applied relaxation with the full ICBT intervention. Recruitment was online and via the intervention platform. Assessments were completed at four-time points including a 2-month follow-up period. The primary outcome was tinnitus severity as measured by the Tinnitus Functional Index. Secondary outcomes were included for anxiety, depression, insomnia, negative tinnitus cognitions, health-related quality of life, hearing disability, and hyperacusis. Treatment engagement variables including the number of logins, number of modules opened, and the number of messages sent. Both an intention-to-treat analysis and completer's only analysis were undertaken.

RESULTS

Engagement was low which compromised results as the full intervention was undertaken by few participants. Both the ICBT and applied relaxation resulted in large reduction of tinnitus severity (within-group effect sizes d = 0.87 and 0.68, respectively for completers only analysis), which were maintained, or further improved at follow-up. These reductions in tinnitus distress were greater for the ICBT group, with a small effect size differences (between-group d = 0.15 in favor of ICBT for completers only analysis). Tinnitus distress decreased the most at post-intervention for those with significant depression at baseline. Both ICBT and applied relaxation contributed to significant reductions on most secondary outcome measures, with no group differences, except for a greater reduction of hyperacusis in the ICBT group.

CONCLUSION

Due to poor compliance partly attributed to the COVID-19 pandemic results were compromised. Further studies employing strategies to improve compliance and engagement are required. The intervention's effectiveness increased with initial level of tinnitus distress; those with the highest scores at intake experienced the most substantial changes on the outcome measures. This may suggest tailoring of interventions according to tinnitus severity. Larger samples are needed to confirm this.

Cognitive-behavioural therapy for a variety of conditions: an overview of systematic reviews and panoramic meta-analysis

BACKGROUND

Cognitive-behavioural therapy aims to increase quality of life by changing cognitive and behavioural factors that maintain problematic symptoms. A previous overview of cognitive-behavioural therapy systematic reviews suggested that cognitive-behavioural therapy was effective for many conditions. However, few of the included reviews synthesised randomised controlled trials.

OBJECTIVES

This project was undertaken to map the quality and gaps in the cognitive-behavioural therapy systematic review of randomised controlled trial evidence base. Panoramic meta-analyses were also conducted to identify any across-condition general effects of cognitive-behavioural therapy.

DATA SOURCES

The overview was designed with cognitive-behavioural therapy patients, clinicians and researchers. The Cochrane Library, MEDLINE, EMBASE, PsycINFO, Cumulative Index to Nursing and Allied Health Literature, Child Development & Adolescent Studies, Database of Abstracts of Reviews of Effects and OpenGrey databases were searched from 1992 to January 2019.

REVIEW METHODS

Study inclusion criteria were as follows: (1) fulfil the Centre for Reviews and Dissemination criteria; (2) intervention reported as cognitive-behavioural therapy or including one cognitive and one behavioural element; (3) include a synthesis of cognitive-behavioural therapy trials; (4) include either health-related quality of life, depression, anxiety or pain outcome; and (5) available in English. Review quality was assessed with A MeaSurement Tool to Assess systematic Reviews (AMSTAR)-2. Reviews were quality assessed and data were extracted in duplicate by two independent researchers, and then mapped according to condition, population, context and quality. The effects from high-quality reviews were pooled within condition groups, using a random-effect panoramic meta-analysis. If the across-condition heterogeneity was I2 < 75%, we pooled across conditions. Subgroup analyses were conducted for age, delivery format, comparator type and length of follow-up, and a sensitivity analysis was performed for quality.

RESULTS

A total of 494 reviews were mapped, representing 68% (27/40) of the categories of the International Classification of Diseases, Eleventh Revision, Mortality and Morbidity Statistics. Most reviews (71%, 351/494) were of lower quality. Research on older adults, using cognitive-behavioural therapy preventatively, ethnic minorities and people living outside Europe, North America or Australasia was limited. Out of 494 reviews, 71 were included in the primary panoramic meta-analyses. A modest effect was found in favour of cognitive-behavioural therapy for health-related quality of life (standardised mean difference 0.23, 95% confidence interval 0.05 to 0.41, prediction interval -0.05 to 0.50, I2 = 32%), anxiety (standardised mean difference 0.30, 95% confidence interval 0.18 to 0.43, prediction interval -0.28 to 0.88, I2 = 62%) and pain (standardised mean difference 0.23, 95% confidence interval 0.05 to 0.41, prediction interval -0.28 to 0.74, I2 = 64%) outcomes. All condition, subgroup and sensitivity effect estimates remained consistent with the general effect. A statistically significant interaction effect was evident between the active and non-active comparator groups for the health-related quality-of-life outcome. A general effect for depression outcomes was not produced as a result of considerable heterogeneity across reviews and conditions.

LIMITATIONS

Data extraction and analysis were conducted at the review level, rather than returning to the individual trial data. This meant that the risk of bias of the individual trials could not be accounted for, but only the quality of the systematic reviews that synthesised them.

CONCLUSION

Owing to the consistency and homogeneity of the highest-quality evidence, it is proposed that cognitive-behavioural therapy can produce a modest general, across-condition benefit in health-related quality-of-life, anxiety and pain outcomes.

FUTURE WORK

Future research should focus on how the modest effect sizes seen with cognitive-behavioural therapy can be increased, for example identifying alternative delivery formats to increase adherence and reduce dropout, and pursuing novel methods to assess intervention fidelity and quality.

Relational counselling as a psychosocial intervention for dementia: Qualitative evidence from people living with dementia and family members

Counselling and other psychotherapeutic interventions can be offered to people with dementia and their caregivers, to treat specific conditions or symptoms (e.g. affective disorders such as depression). Psychotherapeutic interventions also offer the opportunity for individuals with dementia and their families/caregivers to engage in psychological support for a wide range of presentations. However, little is known about how those within this demographic who receive these interventions perceive the experience. This study aimed to understand the experiences of individuals with dementia or caring for someone with dementia, before and after a 12-week relational counselling intervention delivered through a third sector organisation within England. Semi-structured interviews were completed with participants (29 pre-intervention and 25 post-intervention). Framework analysis was conducted, with four main themes identified; expectations and outcomes of counselling, emotional impact of life with dementia, appraisals of identity and importance of therapeutic relationship. Participants reported that counselling interventions addressed a range of needs and concerns that they had, enabling them to reassess and reconsider these. Specific training is needed before therapists deliver therapeutic interventions with people with dementia, to ensure that appropriate support is provided for those with more severe cognitive impairment or who may have fluctuating capacity. Future research should explore the experiences of people with dementia and their caregivers, across different counselling modalities, to establish the appropriateness and effectiveness of relational counselling.

Effectiveness of counselling and psychotherapeutic interventions for people with dementia and their families: a systematic review

As there is currently no cure for dementia, providing psycho-social support is imperative. Counselling and psychotherapeutic interventions offer a way to provide individualised support for people with dementia and their families. However, to date, there has not been a systematic review examining the research evidence for these interventions. This review aimed to examine the following research questions: (1) Are counselling/psychotherapeutic interventions effective for people with dementia?, (2) Are counselling/psychotherapeutic interventions effective for care-givers of people with dementia? and (3) Which modes of delivery are most effective for people with dementia and care-givers of people with dementia? A systematic literature search was conducted in MEDLINE (via PubMed), PsycINFO and CINAHL in March 2019. Keyword searches were employed with the terms ‘dement*’, ‘counsel*’, ‘psychotherapy’, ‘therap*’, ‘care’ and ‘outcome’, for the years 2000–2019. Thirty-one papers were included in the review, from seven countries. Twenty studies were randomised controlled trials (RCTs) or adopted a quasi-experimental design. The remaining studies were qualitative or single-group repeated-measures design. The review identified variation in the counselling/psychotherapeutic approaches and mode of delivery. Most interventions adopted either a problem-solving or cognitive behavioural therapy approach. Mixed effectiveness was found on various outcomes. The importance of customised modifications for people with dementia was highlighted consistently. Understanding the dyadic relationships between people with dementia and their care-givers is essential to offering effective interventions and guidance for practitioners is needed. Information about the cognitive impairment experienced by participants with dementia was poorly reported and is essential in the development of this research area. Future studies should consider the impact of cognitive impairment in developing guidance for counselling/psychotherapeutic intervention delivery for people with dementia.

Evaluation of the effect of aroma oil as a bath salt on cognitive function

BACKGROUND

Aromatherapy is a non-pharmacological therapy for the improvement of dementia symptoms. This study aimed to assess the effects of aroma oil as a bath salt on cognitive function, olfactory function and sleep quality.

METHODS

This was a randomised controlled trial. Overall, 49 patients were able to provide consent, and 35 were finally analysed (Alzheimer's disease: 10, mild cognitive impairment: 25). The patients were randomly assigned to use 0.1%, 0.5% or 1% aroma bath salt. During daily bathing, bath salt was added to the bath water, and the subjects remained in the bathroom for ≥10 min. The intervention period was 24 weeks, and the observation periods were 4 weeks before and after using the aroma bath salt. We performed the Touch Panel-type Dementia Assessment Scale (TDAS), the Odour Stick Identification Test for Japanese (OSIT-J) and the Japanese version of the Pittsburgh Sleep Quality Index (PSQI-J) five times during the before and after observation periods and after the 12-week intervention.

RESULTS

There were no significant changes in the TDAS, OSIT-J and PSQI-J scores before and after the intervention in all groups. Moreover, there were no significant differences in the TDAS, OSIT-J and PSQI-J scores between the groups before and after the intervention. In the correlation analysis of changes in the TDAS and other tests during the intervention period, significant associations between TDAS and sleep latency and sleep disturbances, which are sub-items of PSQI-J, were observed in the use of 0.1% aroma bath salt group.

CONCLUSIONS

The use of aroma bath salt was not associated with improvement in cognitive function, olfactory function or sleep quality. However, sleep-related aspects were associated with changes in cognitive function before and after use of aroma bath salt, which suggested that there is a link between improvements in sleep and that in cognitive function.

Addressing Behavioral Symptoms of Dementia Through STAR-VA Implementation: Do Outcomes Vary by Behavior Type?

OBJECTIVES

The STAR-VA program in Veterans Health Administration Community Living Centers (CLCs, nursing home settings) trains teams to implement a psychosocial intervention with residents with behavioral symptoms of dementia (BSD).

METHODS

Across 71 CLCs, 302 residents selected as training cases had target behaviors categorized into one of 5 types: physically aggressive (PA), physically nonaggressive, verbally aggressive, verbally nonaggressive, and behavior deficit (BD).

RESULTS

Across all groups, there were significant declines in team-rated behavior frequency (36%) and severity (44%), agitation (10%), distress behaviors (42%), depression (17%), and anxiety (20%). The magnitude of changes varied across behavior category. For example, those with a PA target behavior experienced a greater percentage decline in agitation and distress behavior scores, and those with a BD target behavior experienced a greater percentage decline in depressive and anxiety symptoms.

CONCLUSIONS

STAR-VA, a multicomponent intervention, is generally effective across various types of behavioral symptoms associated with dementia.

Psychological Interventions for People with Huntington's Disease: A Call to Arms

BACKGROUND

Although Huntington's disease (HD) can cause a wide range of psychological difficulties, no review has ever been carried out on the range of psychological interventions adopted with this population.

OBJECTIVE

To scope the literature on psychological interventions for psychological difficulties in people affected by HD.

METHODS

A systematic scoping review was performed across MEDLINE, PsycINFO, CINAHL, Academic Search Ultimate, and Cochrane Library up to 1 March 2020.

RESULTS

From an initial return of 1579 citations, a total of nine papers were considered eligible for review. These included a qualitative investigation, three case studies, two case series, two uncontrolled pretest-posttest designs, and only one randomised control trial (RCT). Despite the wide range of psychological difficulties which can be experienced by people affected by the HD gene expansion, the adopted interventions only accounted for five main psychological outcomes (anxiety, apathy, depression, irritability, and coping). Further discussion and suggestions for future research are provided for each outcome.

CONCLUSION

The current literature on psychological interventions in people affected by HD is extremely limited both in terms of methods and addressed clinical outcomes. Consequently, no conclusions can be offered yet as to which psychological therapy may help this population. As further more comprehensive research is urgently needed for this group, the ultimate aim of the present review is to act as a call to arms for HD researchers worldwide to help shed light on the most effective way to translate psychological theory into practice for the benefit of people affected by HD.

Effects of creative expression therapy on Chinese elderly patients with dementia: an exploratory randomized controlled trial

Purpose: This study aimed to evaluate the effect of creative expression (CE) therapy on cognition, communication, emotion, and quality-of-life in people with dementia. Methods: One hundred individuals were included in this study, of whom 91 completed the study (mean age=84.33). The participants were randomly assigned to an intervention group (n=43) and a control group (n=48), and received the CE program or standard cognitive (SC) training twice a week for 6 weeks, respectively. Both groups were submitted to extensive neuropsychological tests, as follows - Mini-Mental State Examination (MMSE), Quality of Life-Alzheimer's Disease (QOL-AD), Cornell Scale for Depression in Dementia (CSDD), Functional Assessment of Communication Skills (FACS) at baseline, 1-, and 4 -weeks post-intervention, and the Observed Emotion Rating Scale (OERS) was measured during the intervention period at weeks 3 and 6. Results: The participants demonstrated significant improvements in cognitive function, quality-of-life, depression degree, communication ability, and emotion status (P<0.05) at post-intervention, which were maintained at 1-month follow-up. Conclusion: This study provides preliminary evidence that CE therapy developed in the study benefits elderly Chinese with dementia. The findings indicated that non-pharmacological intervention programs - CE therapy - can be applied in the management of neuropsychiatric symptoms of dementia.
