Behavioral treatment of depression in dementia patients: a controlled clinical trial

The treatment of behavioural and psychological symptoms in dementia: pragmatic recommendations

Behavioural and psychological symptoms of dementia (BPSD) are a clinical challenge for the lack of a sound taxonomy, frequent presentation with comorbid BPSD, lack of specific pharmacologic interventions, poor base of methodologically sound evidence with randomized clinical trials, contamination from the treatment of behavioural disturbances of young and adult psychiatric conditions, and small efficacy window of psychotropic drugs. We present here a treatment workflow based on a concept-driven literature review based on the notions that (i) the aetiology of BPSD can be mainly neurobiological (so-called 'primary' symptoms) or mainly environmental and functional ('secondary' symptoms) and that this drives treatment; (ii) the clinical efficacy of psychotropic drugs is driven by their specific profile of receptor affinity; (iii) drug treatment should follow the rules of 'start low-go slow, prescribe and revise'. This article argues in support of the distinction between primary and secondary BPSD, as well as their characteristics, which until now have been just sketchily described in the literature. It also offers comprehensive and pragmatic clinician-oriented recommendations for the treatment of BPSD.

[Preventing emotional disorders in the elderly with programs based on cognitive-behavioral therapies]

The cognitive-behavioral approach is particularly well-suited to older people who are looking for a short-term therapeutic solution to many emotional problems, without necessarily resorting to psychotropic drugs. One of the major advantages of this type of psychological treatment is that it helps seniors develop coping skills that can be beneficial in both the short and long term. However, some adjustments are sometimes necessary to achieve this goal.

Virtual reality-based dementia educational programmes for formal and informal caregivers of people with dementia: A scoping review

AIM

To map evidence of the existing virtual reality-based dementia educational programmes and the effects of these educational programmes on dementia formal and informal caregivers.

DESIGN

A scoping review.

METHODS

A comprehensive search of nine databases was conducted to find studies from the inception of the databases to October 2023. Two authors independently screened the titles and abstracts related to the eligibility criteria. Full texts of potentially relevant studies were read by one author and checked by a second. Data extraction and synthesis using NVivo 12 were undertaken by one author and checked by two other authors.

RESULTS

Nineteen studies published between 2002 and 2022. The four randomised controlled studies and five qualitative studies were of moderate to good methodological quality. The 10 quasi-experimental studies were of weak to moderate quality. Fifteen virtual reality-based educational programmes had a positive influence on formal and informal caregivers, including improving caregivers' perceptions changing attitudes towards people with dementia, while the nursing competence of formal caregivers did not improve in short term. Educational programmes that covered dementia-related information and care strategies better improved the knowledge level of dementia formal and informal caregivers.

CONCLUSIONS

The qualitative and quantitative studies of moderate to good quality included in this study support the idea that virtual reality-based dementia educational programmes may be a safe and effective way and have potential benefits for improving knowledge, perceptions, attitudes and nursing competence.

IMPACT

This scoping review will provide an emerging teaching model for formal and informal caregivers of people with dementia and help them better understand the types and the influence of virtual reality-based dementia educational programmes.

Community of trauma care partnering with stakeholders to improve injury outcomes: focus group analysis

Introduction

Engaging trauma survivors/caregivers results in research findings that are more relevant to patients' needs and priorities. Although their perspectives increase research significance, there is a lack of understanding about how best to incorporate their insights. We aimed to capture stakeholder perspectives to ensure research is meaningful, respectful, and relevant to the injured patient and their caregivers.

Methods

A multiphase, inductive exploratory qualitative study was performed, the first phase of which is described here. Virtual focus groups to elicit stakeholder perspectives and preferences were conducted across 19 trauma centers in the USA during 2022. Discussion topics were chosen to identify patients' motivation to join research studies, preferences regarding consent, suggestions for increasing diversity and access, and feelings regarding outcomes, efficacy, and exception from informed consent. The focus groups were audio recorded, transcribed, coded, and analyzed to identify the range of perspectives expressed and any common themes that emerged.

Results

Ten 90-minute focus groups included patients/caregiver (n=21/1) and researchers (n=14). Data analysis identified common themes emerging across groups. The importance of trust and preexisting relationships with the clinical care team were the most common themes across all groups.

Conclusion

Our findings reveal common themes in preferences, motivations, and best practices to increase patient/caregiver participation in trauma research. The project's next phases are distribution of a vignette-based survey to establish broad stakeholder consensus; education and dissemination activities to share strategies that increase research engagement and relevance for patients; and the formation of a panel of patients to support future research endeavors.

The Interface between Depression and Alzheimer's Disease. A Comprehensive Approach

Depression and Alzheimer's disease (AD) are frequent interacting diseases in the elderly with a negative impact on the quality of life of patients and caregivers. Late-life depression may be regarded either as an early symptom of AD or a risk factor for AD, depending on the context. This review was focused on the latest developments in the fields of the neurobiological basis and treatment of depression in AD. We found that some plausible hypotheses are emerging to correlate with depression in AD, such as neuroinflammation and dysimmune regulation. It seems that depression is not related to amyloid deposition, but this issue is not completely resolved. The response to antidepressants is controversial according to the evidence from 10 small double-blind randomized placebo-controlled clinical trials with antidepressants in AD patients with depression: four with sertraline, one with three arms (sertraline, mirtazapine, placebo), one with fluoxetine, one with imipramine, one with clomipramine, one with escitalopram, and one with vortioxetine. The total number of treated patients completing the trials was 638. The main criterion of a positive response was a reduction in the scores of clinical scales for depression of at least 50%. The weighted OR (odds ratio) was calculated with the method of Mantel-Haenszel: 1.29; 95% CI: 0.77-2.16. No significant differences were found compared with placebo. Antidepressants did not have a meaningful negative influence on cognition, which was measured with the mini-mental state examination (MMSE) in 18 clinical trials. Alternatives other than drugs are also discussed. Although there have been important advances in this field, pathophysiology and treatment deserve further research.

Individual behavioral activation in the treatment of depression: A meta analysis

OBJECTIVE

Behavioral activation (BA) is an extensively examined treatment for depression which is relatively simple to apply in comparison to other psychotherapies. BA aims to increase positive interactions between a person and the environment. All previous meta-analyses focused on BA in groups and guided self-help, but none focused on BA in individual psychotherapy. The goal of the current meta-analysis is to examine the pooled effects of trials comparing individual BA to control conditions.

METHODS

We conducted systematic searches and conducted random effects meta-analyses to examine the effects of BA.

RESULTS

We included 22 randomized controlled trials (with 819 patients) comparing individual behavioral activation with waitlist, usual care, or other control conditions on distal treatment outcomes. Nine studies were rated as low risk of bias. We found a large effect (Hedges' g = 0.85; 95% CI: 0.57; 1.1) with high heterogeneity (75%; 95% CI: 62; 83). When only studies with low risk of bias were considered, the effect size was still significant (g = 0.56; 95% CI: 0.09; 1.03), with high heterogeneity (I² = 80%; 95% CI: 66; 89; prediction interval: -0.85; 1.98).

CONCLUSION

BA is an effective, relatively simple type of therapy that can be applied broadly in differing populations/.

Rationale for a Multi-Factorial Approach for the Reversal of Cognitive Decline in Alzheimer's Disease and MCI: A Review

Alzheimer's disease (AD) is a multifactorial, progressive, neurodegenerative disease typically characterized by memory loss, personality changes, and a decline in overall cognitive function. Usually manifesting in individuals over the age of 60, this is the most prevalent type of dementia and remains the fifth leading cause of death among Americans aged 65 and older. While the development of effective treatment and prevention for AD is a major healthcare goal, unfortunately, therapeutic approaches to date have yet to find a treatment plan that produces long-term cognitive improvement. Drugs that may be able to slow down the progression rate of AD are being introduced to the market; however, there has been no previous solution for preventing or reversing the disease-associated cognitive decline. Recent studies have identified several factors that contribute to the progression and severity of the disease: diet, lifestyle, stress, sleep, nutrient deficiencies, mental health, socialization, and toxins. Thus, increasing evidence supports dietary and other lifestyle changes as potentially effective ways to prevent, slow, or reverse AD progression. Studies also have demonstrated that a personalized, multi-therapeutic approach is needed to improve metabolic abnormalities and AD-associated cognitive decline. These studies suggest the effects of abnormalities, such as insulin resistance, chronic inflammation, hypovitaminosis D, hormonal deficiencies, and hyperhomocysteinemia, in the AD process. Therefore a personalized, multi-therapeutic program based on an individual's genetics and biochemistry may be preferable over a single-drug/mono-therapeutic approach. This article reviews these multi-therapeutic strategies that identify and attenuate all the risk factors specific to each affected individual. This article systematically reviews studies that have incorporated multiple strategies that target numerous factors simultaneously to reverse or treat cognitive decline. We included high-quality clinical trials and observational studies that focused on the cognitive effects of programs comprising lifestyle, physical, and mental activity, as well as nutritional aspects. Articles from PubMed Central, Scopus, and Google Scholar databases were collected, and abstracts were reviewed for relevance to the subject matter. Epidemiological, pathological, toxicological, genetic, and biochemical studies have all concluded that AD represents a complex network insufficiency. The research studies explored in this manuscript confirm the need for a multifactorial approach to target the various risk factors of AD. A single-drug approach may delay the progression of memory loss but, to date, has not prevented or reversed it. Diet, physical activity, sleep, stress, and environment all contribute to the progression of the disease, and, therefore, a multi-factorial optimization of network support and function offers a rational therapeutic strategy. Thus, a multi-therapeutic program that simultaneously targets multiple factors underlying the AD network may be more effective than a mono-therapeutic approach.

Parent training for dependent, yet abled, young adults

The term Failure to launch (FTL) has been used to describe abled adults who do not work, do not attend school, and live with- and at the expense of-their parents. FTL can be beneficially addressed through parent training, a treatment method that is rarely used with adults (i.e., individuals past the age of majority). The authors first review the goals of parent training programs offered to parents of adults. The review demonstrates that these goals dovetail with key aspects of FTL. The authors then describe a new parent training approach for parents of individuals with FTL, based on SPACE (Supportive Parenting for Anxious Childhood Emotions). They highlight five key components of SPACE-FTL: Psychoeducation, Reducing Parental Accommodation, Increasing Parental Support, De-Escalation, and Engaging Supporters. The authors conclude by discussing SPACE-FTL in relation and comparison to other parent training programs and their components.

A Systematic Review of Ethnoracial Participation in Randomized Clinical Trials of Behavioral Activation

As of the last available NIH report, people of color (POC) constituted 28.1% of enrollment across all U.S. domestic clinical trials. The literature on prevalence rates of depression among POC is mixed. While the prevalence rates of depression may vary across POC, it remains unknown to what degree POC have been included in outcome clinical trials of depression since NIH's mandates for inclusion of minorities in clinical outcome research. Following PRISMA guidelines, the present review identified randomized controlled trials of behavioral activation from 1989 to 2021 using the following search engines: PsycINFO, EMBASE, and Cochrane Central Register of Controlled Trials. We reviewed 5,247 articles and included 28 articles that met full inclusion criteria (n = 5,169 participants). Across studies included in this review, 70% were non-Latinx White, 14.1% were African American, 8.9% were Latinx, 0.5% were Asian, 2.9% were other, and 3.7% were unknown. Results indicated an increase in representation of ethnoracial inclusion rates across time and that recruitment method was not associated with adequate inclusion of POC. However, the university setting was associated with inadequate representation of POC.

A Systematic Review and Meta-Analysis of Dyadic Psychological Interventions for BPSD, Quality of Life and/or Caregiver Burden in Dementia or MCI

Objectives: This systematic review and meta-analysis assesses the effectiveness of psychological interventions that involve people with dementia or mild cognitive impairment (MCI) and their informal caregivers, and target improvements in the management of the behavioral and psychological symptoms of dementia (BPSD); quality of life; and/or burden reduction for people with either dementia or MCI and their informal caregivers.Methods: Studies were identified through database searches (Cochrane Library, CENTRAL, CINAHL, EMBASE, MEDLINE and PsychINFO) and clinical trials registers (ClinicalTrials.gov and http://apps.who.int/trialsearch/). Data were pooled for meta-analysis.Results: Database and reference list searches identified 1,878 references, of which fourteen studies were included. Positive effects were found on the anxiety symptoms of people with dementia on the RAID scale; on the quality of life of people with dementia on the self-rated QoL-AD scale; and on informal caregiver burden on the Zarit Burden Interview.Conclusions: Psychological interventions involving whole dyads have some promise for both people with dementia and informal caregivers, but are still far from uniformly effective across BPSD, quality of life, and caregiver burden. Further research directions are discussed.Clinical Implications: The results suggest that clinicians should routinely involve both halves of the dyad when delivering psychological interventions targeting anxiety or quality of life for people with dementia, or burden for informal caregivers.

Psychological treatments for depression and anxiety in dementia and mild cognitive impairment

BACKGROUND

Experiencing anxiety and depression is very common in people living with dementia and mild cognitive impairment (MCI). There is uncertainty about the best treatment approach. Drug treatments may be ineffective and associated with adverse effects. Guidelines recommend psychological treatments. In this updated systematic review, we investigated the effectiveness of different psychological treatment approaches.

OBJECTIVES

Primary objective To assess the clinical effectiveness of psychological interventions in reducing depression and anxiety in people with dementia or MCI. Secondary objectives To determine whether psychological interventions improve individuals' quality of life, cognition, activities of daily living (ADL), and reduce behavioural and psychological symptoms of dementia, and whether they improve caregiver quality of life or reduce caregiver burden.

SEARCH METHODS

We searched ALOIS, the Cochrane Dementia and Cognitive Improvement Group's register, MEDLINE, Embase, four other databases, and three trials registers on 18 February 2021.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) that compared a psychological intervention for depression or anxiety with treatment as usual (TAU) or another control intervention in people with dementia or MCI.

DATA COLLECTION AND ANALYSIS

A minimum of two authors worked independently to select trials, extract data, and assess studies for risk of bias. We classified the included psychological interventions as cognitive behavioural therapies (cognitive behavioural therapy (CBT), behavioural activation (BA), problem-solving therapy (PST)); 'third-wave' therapies (such as mindfulness-based cognitive therapy (MBCT)); supportive and counselling therapies; and interpersonal therapies. We compared each class of intervention with control. We expressed treatment effects as standardised mean differences or risk ratios. Where possible, we pooled data using a fixed-effects model. We used GRADE methods to assess the certainty of the evidence behind each result.

MAIN RESULTS

We included 29 studies with 2599 participants. They were all published between 1997 and 2020. There were 15 trials of cognitive behavioural therapies (4 CBT, 8 BA, 3 PST), 11 trials of supportive and counselling therapies, three trials of MBCT, and one of interpersonal therapy. The comparison groups received either usual care, attention-control education, or enhanced usual care incorporating an active control condition that was not a specific psychological treatment. There were 24 trials of people with a diagnosis of dementia, and five trials of people with MCI. Most studies were conducted in community settings. We considered none of the studies to be at low risk of bias in all domains.  Cognitive behavioural therapies (CBT, BA, PST) Cognitive behavioural therapies are probably slightly better than treatment as usual or active control conditions for reducing depressive symptoms (standardised mean difference (SMD) -0.23, 95% CI -0.37 to -0.10; 13 trials, 893 participants; moderate-certainty evidence). They may also increase rates of depression remission at the end of treatment (risk ratio (RR) 1.84, 95% CI 1.18 to 2.88; 2 studies, with one study contributing 2 independent comparisons, 146 participants; low-certainty evidence). We were very uncertain about the effect of cognitive behavioural therapies on anxiety at the end of treatment (SMD -0.03, 95% CI -0.36 to 0.30; 3 trials, 143 participants; very low-certainty evidence). Cognitive behavioural therapies probably improve patient quality of life (SMD 0.31, 95% CI 0.13 to 0.50; 7 trials, 459 participants; moderate-certainty evidence) and activities of daily living at end of treatment compared to treatment as usual or active control (SMD -0.25, 95% CI -0.40 to -0.09; 7 trials, 680 participants; moderate-certainty evidence). Supportive and counselling interventions Meta-analysis showed that supportive and counselling interventions may have little or no effect on depressive symptoms in people with dementia compared to usual care at end of treatment (SMD -0.05, 95% CI -0.18 to 0.07; 9 trials, 994 participants; low-certainty evidence). We were very uncertain about the effects of these treatments on anxiety, which was assessed only in one small pilot study. Other interventions There were very few data and very low-certainty evidence on MBCT and interpersonal therapy, so we were unable to draw any conclusions about the effectiveness of these interventions.

AUTHORS' CONCLUSIONS

CBT-based treatments added to usual care probably slightly reduce symptoms of depression for people with dementia and MCI and may increase rates of remission of depression. There may be important effect modifiers (degree of baseline depression, cognitive diagnosis, or content of the intervention). CBT-based treatments probably also have a small positive effect on quality of life and activities of daily living. Supportive and counselling interventions may not improve symptoms of depression in people with dementia. Effects of both types of treatment on anxiety symptoms are very uncertain. We are also uncertain about the effects of other types of psychological treatments, and about persistence of effects over time. To inform clinical guidelines, future studies should assess detailed components of these interventions and their implementation in different patient populations and in different settings.

The MOMANT study, a caregiver support programme with activities at home for people with dementia: a study protocol of a randomised controlled trial

BACKGROUND

Because of the expected increase in the number of people with dementia, and the associated social and economic costs, there is an urgent need to develop effective and cost-effective care for people with dementia and their caregivers. The intervention proposed here combines two approaches to caregiver support that have shown to be effective in empowering caregivers, i.e., multiple components for caregiver support and actively engaging caregivers to involve the person with dementia in activities at home. The aim is to investigate whether the intervention is effective in improving quality of life in the caregiver and the person with dementia. A further aim will be to investigate whether this intervention can improve caregivers' feeling of competence, experience of caregiving, and mood.

METHODS

The study design is a pragmatic, cluster randomised controlled trial with cost-effectiveness analysis. The study participants are informal caregivers and home-living persons with dementia for whom they care, recruited in various regions in the Netherlands. The trial will compare outcomes in two groups of participants: 85 dyads who receive the intervention, and 85 dyads who receive care as usual. The intervention is a caregiver support training that is manual based and consists of 6 group sessions over 2 months. Training takes place in small groups of caregivers led by a health care professional presented at dementia day care centres. Randomisation occurs at the level of the day care centre. Participants are assessed on the outcome measures at baseline, prior to the intervention, and at 3 and 6 months after baseline.

DISCUSSION

The study will provide insight into effectiveness and cost-effectiveness of an intervention that has not previously been evaluated or implemented in the Netherlands. The intervention potentially adds to the effective support options for informal caregivers of people with dementia without greatly increasing the workload for health- or social care professionals.

TRIAL REGISTRATION

The trial is registered at the Dutch Trial Register at NTR6643 ; August 22nd, 2017.

Behavioral activation for live-in migrant home care workers and care recipients in Israel: a pilot study

In a growing global trend, individuals are migrating to other countries to live with and care for older adults with dementia. Although this trend addresses the geriatric workforce shortage, workers and older adults often experience distress. In a pilot study in Israel, six migrant care workers participated in a six-week group intervention in which they learned to increase valued, enjoyable activities for themselves and the older adult with whom they lived (behavioral activation). After the intervention, workers reported that they increased activities for themselves and the older adult and were satisfied, and quality of life and sense of achievement showed medium and large effect sizes, respectively. Participants suggested adapting the intervention to an online format for greater access. Although findings are tentative, the study points to promising strategies for migrant home care workers: focusing on the worker and older adult and offering online interventions.

Control interventions in randomised trials among people with mental health disorders

BACKGROUND

Control interventions in randomised trials provide a frame of reference for the experimental interventions and enable estimations of causality. In the case of randomised trials assessing patients with mental health disorders, many different control interventions are used, and the choice of control intervention may have considerable impact on the estimated effects of the treatments being evaluated.

OBJECTIVES

To assess the benefits and harms of typical control interventions in randomised trials with patients with mental health disorders. The difference in effects between control interventions translates directly to the impact a control group has on the estimated effect of an experimental intervention. We aimed primarily to assess the difference in effects between (i) wait-list versus no-treatment, (ii) usual care versus wait-list or no-treatment, and (iii) placebo interventions (all placebo interventions combined or psychological, pharmacological, and physical placebos individually) versus wait-list or no-treatment. Wait-list patients are offered the experimental intervention by the researchers after the trial has been finalised if it offers more benefits than harms, while no-treatment participants are not offered the experimental intervention by the researchers.

SEARCH METHODS

In March 2018, we searched MEDLINE, PsycInfo, Embase, CENTRAL, and seven other databases and six trials registers.

SELECTION CRITERIA

We included randomised trials assessing patients with a mental health disorder that compared wait-list, usual care, or placebo interventions with wait-list or no-treatment .

DATA COLLECTION AND ANALYSIS

Titles, abstracts, and full texts were reviewed for eligibility. Review authors independently extracted data and assessed risk of bias using Cochrane's risk of bias tool. GRADE was used to assess the quality of the evidence. We contacted researchers working in the field to ask for data from additional published and unpublished trials. A pre-planned decision hierarchy was used to select one benefit and one harm outcome from each trial. For the assessment of benefits, we summarised continuous data as standardised mean differences (SMDs) and dichotomous data as risk ratios (RRs). We used risk differences (RDs) for the assessment of adverse events. We used random-effects models for all statistical analyses. We used subgroup analysis to explore potential causes for heterogeneity (e.g. type of placebo) and sensitivity analyses to explore the robustness of the primary analyses (e.g. fixed-effect model).

MAIN RESULTS

We included 96 randomised trials (4200 participants), ranging from 8 to 393 participants in each trial. 83 trials (3614 participants) provided usable data. The trials included 15 different mental health disorders, the most common being anxiety (25 trials), depression (16 trials), and sleep-wake disorders (11 trials). All 96 trials were assessed as high risk of bias partly because of the inability to blind participants and personnel in trials with two control interventions. The quality of evidence was rated low to very low, mostly due to risk of bias, imprecision in estimates, and heterogeneity. Only one trial compared wait-list versus no-treatment directly but the authors were not able to provide us with any usable data on the comparison. Five trials compared usual care versus wait-list or no-treatment and found a SMD -0.33 (95% CI -0.83 to 0.16, I² = 86%, 523 participants) on benefits. The difference between all placebo interventions combined versus wait-list or no-treatment was SMD -0.37 (95% CI -0.49 to -0.25, I² = 41%, 65 trials, 2446 participants) on benefits. There was evidence of some asymmetry in the funnel plot (Egger's test P value of 0.087). Almost all the trials were small. Subgroup analysis found a moderate effect in favour of psychological placebos SMD -0.49 (95% CI -0.64 to -0.30; I² = 53%, 39 trials, 1656 participants). The effect of pharmacological placebos versus wait-list or no-treatment on benefits was SMD -0.14 (95% CI -0.39 to 0.11, 9 trials, 279 participants) and the effect of physical placebos was SMD -0.21 (95% CI -0.35 to -0.08, I² = 0%, 17 trials, 896 participants). We found large variations in effect sizes in the psychological and pharmacological placebo comparisons. For specific mental health disorders, we found significant differences in favour of all placebos for sleep-wake disorders, major depressive disorder, and anxiety disorders, but the analyses were imprecise due to sparse data. We found no significant differences in harms for any of the comparisons but the analyses suffered from sparse data. When using a fixed-effect model in a sensitivity analysis on the comparison for usual care versus wait-list and no-treatment, the results were significant with an SMD of -0.46 (95 % CI -0.64 to -0.28). We reported an alternative risk of bias model where we excluded the blinding domains seeing how issues with blinding may be seen as part of the review investigation itself. However, this did not markedly change the overall risk of bias profile as most of the trials still included one or more unclear bias domains.

AUTHORS' CONCLUSIONS

We found marked variations in effects between placebo versus no-treatment and wait-list and between subtypes of placebo with the same comparisons. Almost all the trials were small with considerable methodological and clinical variability in factors such as mental health population, contents of the included control interventions, and outcome domains. All trials were assessed as high risk of bias and the evidence quality was low to very low. When researchers decide to use placebos or usual care control interventions in trials with people with mental health disorders it will often lead to lower estimated effects of the experimental intervention than when using wait-list or no-treatment controls. The choice of a control intervention therefore has considerable impact on how effective a mental health treatment appears to be. Methodological guideline development is needed to reach a consensus on future standards for the design and reporting of control interventions in mental health intervention research.

Spousal Care Intensity, Socioeconomic Status, and Depression among the Older Caregivers in China: A Study on 2011–2018 CHARLS Panel Data

Using the stress process model and data from the 2011–2018 China Health and Retirement Longitudinal Study (CHARLS), this study examined the effect of spousal caregiving intensity on the depression level of older caregivers in China. The moderating role that socioeconomic status plays in the relationship between spouses was explored by constructing multilevel growth models (MGMs). The care intensity for a spouse was found to relate to significantly increased depression levels in older caregivers, while the degree of disability of the spouse being cared for (B = 0.200, p < 0.001) having a greater effect on depression than the duration of care (B = 0.007, p < 0.01). There was a threshold effect where the provision of more than 10 h of care per week for a spouse (B = 0.931, p < 0.001; B = 0.970; p < 0.01) or caring for a disabled spouse with limited ADLs (B = 0.709, p < 0.01; B = 1.326; p < 0.001; B = 1.469, p < 0.01) increased depression in older caregivers. There were moderating influences, including higher professional prestige before retirement (B = −0.006, p < 0.05) and higher annual family income (B = −0.037, p < 0.10), that increased depression related to the spouse’s degree of disability. It was considered that active familism measures should be formulated for older spousal caregivers, especially those with lower socioeconomic status.

Feasibility and acceptability of cognitive behavioural therapy in older Japanese people with cognitive decline: a single-arm intervention

Studies have shown that cognitive behavioural therapy (CBT) for older people with cognitive decline and depression/anxiety improves negative moods. However, CBT research focusing on this population in Japan is limited. This study aimed to evaluate the feasibility of a cognitive behavioural program for people with cognitive decline. Sixteen Japanese patients with mild dementia (n = 3) and mild cognitive impairment (MCI, n = 13) participated in the study. A single-arm, pre–post study was implemented in two hospitals in Japan. The CBT program included eight bi-weekly sessions. The feasibility outcomes (satisfaction, understanding and usefulness) were measured immediately after completing the sessions, and depression, anxiety, quality of life (QOL), neuropsychiatric symptoms, and caregiver burden were measured at three time points (i.e. before, immediately after, and 3-month follow-up). Ten MCI participants attended all sessions and the mean patient satisfaction scores using the Client Satisfaction Questionnaire were 31.0±10.05 out of 32. Linear mixed model analyses demonstrated that the time effect was significant for depression (d = 1.62), anxiety (d = 1.39), and QOL (d = 1.00) for the patients, and significant for anxiety (d = 1.08) for their caregivers. The study found that this CBT program is feasible and acceptable for older Japanese people with cognitive decline. The program also improved patients’ QOL, anxiety and depressive symptoms, and decreased caregivers’ anxiety.

Barriers and facilitators to providing CBT for people living with dementia: Perceptions of psychological therapists

Many people living with dementia or mild cognitive impairment (MCI) experience anxiety and depression. Cognitive behavioural therapy (CBT) is a recommended treatment for adults, commonly provided through primary care psychological therapies services. This study explored the facilitators and barriers to providing CBT interventions for people living with dementia or MCI, as perceived by therapists working in such services. Structured interviews were conducted with 14 clinicians recruited through primary care psychological therapies services about their experiences of working with people living with dementia or MCI and their ideas about factors that enhance or hinder offering and delivering CBT to this population. Interview recordings were transcribed and analysed using thematic analysis. Credibility checks were incorporated throughout. Three themes were identified: 'attitudes towards dementia', 'competing demands', and 'pressure without support'. Perceived facilitators and barriers occurred across individual, service, and system levels. Facilitators were positive engagement and outcomes for people living with dementia or MCI, positive attitudes of clinicians, and flexibility within some services. In contrast, perceived barriers were stigma towards dementia and mental health in older adults, high pressure on staff to perform with a lack of support to do so, exclusion based on diagnosis, and inflexibility within some services. Clinicians were confident that people living with dementia or MCI could benefit from CBT, with some adaptations to delivery. There are implications for staff support and training, and for commissioning practices relating to the tension between minimal resources, equitable access, and person-centred care.

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.

Staff Reports of Behavioral Expressions of Persons with Dementia in 250 Assisted Living Communities

BACKGROUND AND OBJECTIVES

Assisted living (AL) residents with dementia commonly exhibit behavioral expressions (BEs), yet no study has examined how AL staff perceive of and respond to BEs in terms of the "ABC" model of antecedents, behaviors and consequences, or how perceptions relate to organizational characteristics. Understanding staff perceptions may inform interventions.

RESEARCH DESIGN AND METHODS

A convergent, mixed-methods design was used in a study of health care supervisors from 250 AL communities in seven states who reported 366 cases of resident BEs (one successful and one unsuccessful case). Qualitative analysis identified antecedents, BEs, staff responses, resident outcomes, and disposition (aging in place or discharge). Content analysis identified themes and compared case types. Descriptive statistics examined organizational characteristics associated with identifying antecedents.

RESULTS

One-quarter of cases recognized antecedents; slightly more were identified in successful (28%) compared to unsuccessful cases (20%); staff in dementia-only and smaller communities identified antecedents more often. Combativeness and anxiety were the most frequently reported BEs. The majority of both types of cases reported staff responses. Medication management was enacted as a response in 40% of cases compared to psychiatric assessment in 33% of cases.

DISCUSSION AND IMPLICATIONS

Staff training is indicated to increase AL staff recognition of antecedents; doing so might reduce use of antipsychotic medications. Psychiatric assessment plays an important role in dementia care in AL and warrants further examination. Results could be helpful for applied behavioral researchers interested in developing ways to improve identification of antecedents of BEs of persons with dementia.

Rejection of Care and Aggression among Older Veterans with Dementia: The Influence of Background Factors and Interpersonal Triggers

OBJECTIVES

To test relationships among background factors, interpersonal triggers, rejection of care, and aggression among veterans living with dementia in residential long-term care settings, based on the need-driven dementia-compromised behavior model.

DESIGN

A mixed methods secondary analysis of program evaluation data from the Staff Training in Assisted Living Residences-Veterans Health Administration intervention implemented by the US Department of Veterans Affairs healthcare system.

SETTING AND PARTICIPANTS

In total, 315 older veterans who participated in the 2013‒2016 Staff Training in Assisted Living Residences-Veterans Health Administration program at 76 Community Living Centers (Veterans Affairs-operated nursing homes).

METHODS

Text data that captured the interdisciplinary team observations of distressed behaviors of concern and their circumstances were coded into categorical variables and then combined with existing quantitative data to test hypothesized relationships using structural equation modeling.

RESULTS

Rejection of care was directly affected by interpersonal triggers (β = 0.32, P < .005) and background factors such as depression (β = 0.29, P < .018), anxiety (β = -0.18, P < .023), and cognitive status (β = 0.10, P < .049). Depression also had an indirect effect on rejection of care through interpersonal triggers (α × β = 0.13 × 0.32 = 0.04, P < .012). Aggression was directly affected by both interpersonal triggers (β = 0.19, P < .009) and functional status (β = 0.17, P < .011). Both function (α × β = 0.12 × 0.19 = 0.02, P < .035) and depression (α × β = 0.13 × 0.19 = 0.03, P < .005) had indirect effects on aggression through interpersonal triggers.

CONCLUSIONS AND IMPLICATIONS

Interpersonal triggers influenced rejection of care and aggression in veterans with dementia. Background factors such as depression and severity of functional impairment increased the likelihood of these symptoms. Study findings emphasize the importance of developing and implementing interventions that improve interpersonal relationships and developing targeted interventions for those with depressive symptoms.

Comparative efficacy of interventions for reducing symptoms of depression in people with dementia: systematic review and network meta-analysis

OBJECTIVE

To describe the comparative efficacy of drug and non-drug interventions for reducing symptoms of depression in people with dementia who experience depression as a neuropsychiatric symptom of dementia or have a diagnosis of a major depressive disorder.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

Medline, Embase, the Cochrane Library, CINAHL, PsycINFO, and grey literature between inception and 15 October 2020.

ELIGIBILITY CRITERIA FOR STUDY SELECTION

Randomised trials comparing drug or non-drug interventions with usual care or any other intervention targeting symptoms of depression in people with dementia.

MAIN OUTCOME MEASURES

Pairs of reviewers screened studies, abstracted aggregate level data, and appraised risk of bias with the Cochrane risk of bias tool, which facilitated the derivation of standardised mean differences and back transformed mean differences (on the Cornell scale for depression in dementia) from bayesian random effects network meta-analyses and pairwise meta-analyses.

RESULTS

Of 22 138 citations screened, 256 studies (28 483 people with dementia) were included. Missing data posed the greatest risk to review findings. In the network meta-analysis of studies including people with dementia without a diagnosis of a major depressive disorder who were experiencing symptoms of depression (213 studies; 25 177 people with dementia; between study variance 0.23), seven interventions were associated with a greater reduction in symptoms of depression compared with usual care: cognitive stimulation (mean difference -2.93, 95% credible interval -4.35 to -1.52), cognitive stimulation combined with a cholinesterase inhibitor (-11.39, -18.38 to -3.93), massage and touch therapy (-9.03, -12.28 to -5.88), multidisciplinary care (-1.98, -3.80 to -0.16), occupational therapy (-2.59, -4.70 to -0.40), exercise combined with social interaction and cognitive stimulation (-12.37, -19.01 to -5.36), and reminiscence therapy (-2.30, -3.68 to -0.93). Except for massage and touch therapy, cognitive stimulation combined with a cholinesterase inhibitor, and cognitive stimulation combined with exercise and social interaction, which were more efficacious than some drug interventions, no statistically significant difference was found in the comparative efficacy of drug and non-drug interventions for reducing symptoms of depression in people with dementia without a diagnosis of a major depressive disorder. Clinical and methodological heterogeneity precluded network meta-analysis of studies comparing the efficacy of interventions specifically for reducing symptoms of depression in people with dementia and a major depressive disorder (22 studies; 1829 patients).

CONCLUSIONS

In this systematic review, non-drug interventions were found to be more efficacious than drug interventions for reducing symptoms of depression in people with dementia without a major depressive disorder.

Managing depressive symptoms in people with mild cognitive impairment and mild dementia with a multicomponent psychotherapy intervention: a randomized controlled trial

OBJECTIVE

To evaluate the feasibility and effectiveness of the CORDIAL program, a psychosocial intervention consisting of cognitive behavioral therapy (CBT), cognitive rehabilitation, and reminiscence to manage depressive symptoms for people with mild cognitive impairment (MCI) or dementia.

DESIGN

We conducted a randomized controlled trial, based on a two-group (intervention and control), pre-/post-intervention design.

SETTING

Participants were recruited from five different old age psychiatry and memory clinics at outpatients' hospitals.

PARTICIPANTS

Hundred and ninety-eight people with MCI or early-stage dementia were included.

INTERVENTION

The intervention group (n = 100) received 11 individual weekly sessions of the CORDIAL program. This intervention includes elements from CBT, cognitive rehabilitation, and reminiscence therapy. The control group (n = 98) received treatment-as-usual.

MEASUREMENTS

We assessed Montgomery-Åsberg Depression Rating Scale (MADRS) (main outcome), Neuropsychiatric Inventory Questionnaire, and Quality of Life in Alzheimer's disease (secondary outcomes) over the course of 4 months and at a 10-month follow-up visit.

RESULTS

A linear mixed model demonstrated that the depressive symptoms assessed by MADRS were significantly more reduced in the intervention groups as compared to the control group (p < 0.001). The effect persisted for 6 months after the intervention. No significant differences between groups were found in neuropsychiatric symptoms or quality of life.

CONCLUSION

Our multicomponent intervention, which comprised 11 individual sessions of CBT, cognitive rehabilitation, and reminiscence therapy, reduced depressive symptoms in people with MCI and dementia.

Behavioural activation therapy for post-stroke depression: the BEADS feasibility RCT

BACKGROUND

There is currently insufficient evidence for the clinical effectiveness and cost-effectiveness of psychological therapies for post-stroke depression.

OBJECTIVE

To evaluate the feasibility of undertaking a definitive trial to evaluate the clinical effectiveness and cost-effectiveness of behavioural activation (BA) compared with usual stroke care for treating post-stroke depression.

DESIGN

Parallel-group, feasibility, multicentre, randomised controlled trial with nested qualitative research and a health economic evaluation.

SETTING

Acute and community stroke services in three sites in England.

PARTICIPANTS

Community-dwelling adults 3 months to 5 years post stroke who are depressed, as determined by the Patient Health Questionnaire-9 (PHQ-9) or the Visual Analogue Mood Scales 'Sad' item. Exclusions: patients who are blind and/or deaf, have dementia, are unable to communicate in English, do not have mental capacity to consent, are receiving treatment for depression at the time of stroke onset or are currently receiving psychological intervention.

RANDOMISATION AND BLINDING

Participants were randomised (1 : 1 ratio) to BA or usual stroke care. Randomisation was conducted using a computer-generated list with random permuted blocks of varying sizes, stratified by site. Participants and therapists were aware of the allocation, but outcome assessors were blind.

INTERVENTIONS

The intervention arm received up to 15 sessions of BA over 4 months. BA aims to improve mood by increasing people's level of enjoyable or valued activities. The control arm received usual care only.

MAIN OUTCOME MEASURES

Primary feasibility outcomes concerned feasibility of recruitment to the main trial, acceptability of research procedures and measures, appropriateness of baseline and outcome measures, retention of participants and potential value of conducting the definitive trial. Secondary feasibility outcomes concerned the delivery of the intervention. The primary clinical outcome 6 months post randomisation was the PHQ-9. Secondary clinical outcomes were Stroke Aphasic Depression Questionnaire - Hospital version, Nottingham Leisure Questionnaire, Nottingham Extended Activities of Daily Living, Carer Strain Index, EuroQol-5 Dimensions, five-level version and health-care resource use questionnaire.

RESULTS

Forty-eight participants were recruited in 27 centre-months of recruitment, at a recruitment rate of 1.8 participants per centre per month. The 25 participants randomised to receive BA attended a mean of 8.5 therapy sessions [standard deviation (SD) 4.4 therapy sessions]; 23 participants were allocated to usual care. Outcome assessments were completed by 39 (81%) participants (BA, n = 18; usual care, n = 21). Mean PHQ-9 scores at 6-month follow-up were 10.1 points (SD 6.9 points) and 14.4 points (SD 5.1 points) in the BA and control groups, respectively, a difference of -3.8 (95% confidence interval -6.9 to -0.6) after adjusting for baseline PHQ-9 score and centre, representing a reduction in depression in the BA arm. Therapy was delivered as intended. BA was acceptable to participants, carers and therapists. Value-of-information analysis indicates that the benefits of conducting a definitive trial would be likely to outweigh the costs. It is estimated that a sample size of between 580 and 623 participants would be needed for a definitive trial.

LIMITATIONS

Target recruitment was not achieved, although we identified methods to improve recruitment.

CONCLUSIONS

The Behavioural Activation Therapy for Depression after Stroke trial was feasible with regard to the majority of outcomes. The outstanding issue is whether or not a sufficient number of participants could be recruited within a reasonable time frame for a definitive trial. Future work is required to identify whether or not there are sufficient sites that are able to deliver the services required for a definitive trial.

The Effectiveness of the Positive Mood and Active Life Program on Reducing Depressive Symptoms in Long-Term Care Facilities

BACKGROUND AND OBJECTIVES

Depression is prevalent among long-term care facility (LTCF) residents. However, interventions are not normally part of the management of these residents due to a shortage of mental health professionals. On the basis of Lewinsohn's behavioral model of depression, we developed a 12-week pleasant activity scheduling intervention, the Positive Mood and Active Life (PMAL) program. This study evaluated the effectiveness of the PMAL program on reducing depressive symptoms and improving quality of life among at-risk LTCF residents.

RESEARCH DESIGN AND METHODS

We adopted a cluster randomized controlled trial design. Four LTCFs were randomly assigned as treatment sites and three provided care as usual. At-risk LTCF residents (N = 68) were identified using the Mood Resident Assessment Protocol from the Minimum Data Set 2.0. The PMAL program was delivered to 34 residents. The primary and secondary outcomes were depressive symptoms and quality of life, as measured by the Geriatric Depression Scale-15 (GDS-15) and the World Health Organization Quality of Life scale-BREF (WHOQoL-BREF), respectively.

RESULTS

After 12 weeks, the GDS-15 score in the intervention group showed a reduction from 7.59 to 5.67, with a significant treatment by time effect (p = .006), based on the mixed model analysis; the WHOQoL-BREF score also substantially increased from 69.83 to 86.61 (p = .000).

DISCUSSION AND IMPLICATIONS

The PMAL program is effective in reducing depressive symptoms of at-risk LTCF residents. It is a feasible intervention that requires minimum resources and can be integrated with standardized assessment systems.

The Intersection of Falls and Dementia in Primary Care: Evaluation and Management Considerations

A large body of research has addressed the assessment and management of fall risk among community-dwelling older adults. Persons with dementia are at higher risk for falls and fall-related injuries, yet less is known about effective strategies for reducing falls and injuries among those with dementia. Falls and dementia are regularly considered to be discrete conditions and are often managed separately. Increasing evidence shows that these conditions frequently co-occur, and one may precede the other. This article explores the relationship between falls and dementia, including the importance of rehabilitation strategies for reducing fall risk in these individuals.

Comparing patient and informant ratings of depressive symptoms in various stages of Alzheimer's disease

OBJECTIVE

Using a multimethod approach, this study assessed the relationship between patient and informant ratings of depression in Alzheimer's disease (AD) in a manner that better represents the progressive course of AD, and allows for elucidation of specific cognitive domains that may explain changes in respondent agreement.

METHOD

Case data (N = 16,297) were provided by the National Alzheimer's Coordinating Center (NACC). A series of contingency analyses were performed to assess the relationship between patient and informant agreement across levels of impairment in individuals with AD. Patients and informants were placed into groups (i.e., not impaired, mild impairment, moderate impairment, severe impairment) based on patients' performance on multiple indicators of global cognitive functioning, as well as measures of attention, working memory, processing speed, executive functioning, language, and episodic learning and memory.

RESULTS

Across measures, greater impairment was significantly (p < .001) associated with decreases in patient-informant congruence and increases in rates of patients denying depression when informants endorsed observing features of the same. These inconsistencies were most pronounced in the mildest stages of impairment. For a subset of the sample, rates of patients reporting depressive symptoms when informants denied observing the same also increased alongside worsening impairment. Incremental impairment in episodic learning (χ² = 805.25) and memory (χ² = 856.94) performance were most closely associated with decreases in respondent agreement. Patient-informant relationship type did not appear to mediate the response patterns observed.

CONCLUSIONS

Mild impairment in AD patients, particularly in episodic learning and memory functioning, is significantly associated with decreases in patient-informant agreement regarding the presence of depressive symptoms. These results suggest that even at the earliest stages of AD informant reports should be used to corroborate patients' reporting. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Improving mental health and reducing antipsychotic use in people with dementia in care homes: the WHELD research programme including two RCTs

Background

The effective management of agitation and other neuropsychiatric and behavioural symptoms in people with dementia is a major challenge, particularly in care home settings, where dementia severity is higher and there is limited training and support for care staff. There is evidence for the value of staff training and the use of psychosocial approaches; however, no intervention currently exists that combines these elements into an intervention that is fit for purpose and effective in these settings based on evidence from a randomised controlled trial.

Objective

The objective was to develop and evaluate a complex intervention to improve well-being, reduce antipsychotic use and improve quality of life in people with dementia in care homes through person-centred care, management of agitation and non-drug approaches.

Design

This was a 5-year programme that consisted of six work packages. Work package 1 consisted of two systematic reviews of personalised psychosocial interventions for behavioural and psychological symptoms for people with dementia in care homes. Work package 2 consisted of a metasynthesis of studies examining implementation of psychosocial interventions, in addition to developing a draft Well-being and Health for people with Dementia (WHELD) programme. Work package 3 consisted of a factorial study of elements of the draft WHELD programme in 16 care homes. Work package 4 involved optimisation of the WHELD programme based on work package 3 data. Work package 5 involved a multicentre randomised controlled trial in 69 care homes, which evaluated the impact of the optimised WHELD programme on quality of life, agitation and overall neuropsychiatric symptoms in people with dementia. Work package 6 focused on dissemination of the programme.

Setting

This programme was carried out in care homes in the UK.

Participants

Participants of this programme were people with dementia living in care homes, and the health and care professionals providing treatment and care in these settings.

Results

Work package 1: reviews identified randomised controlled trials and qualitative evidence supporting the use of psychosocial approaches to manage behavioural symptoms, but highlighted a concerning lack of evidence-based training manuals in current use. Work package 2: the meta-analysis identified key issues in promoting the use of interventions in care homes. The WHELD programme was developed through adaptation of published approaches. Work package 3: the factorial trial showed that antipsychotic review alone significantly reduced antipsychotic use by 50% (odds ratio 0.17, 95% confidence interval 0.05 to 0.60). Antipsychotic review plus social interaction significantly reduced mortality (odds ratio 0.36, 95% confidence interval 0.23 to 0.57), but this group showed significantly worse outcomes in behavioural and psychological symptoms of dementia than the group receiving neither antipsychotic review nor social interaction (mean difference 7.37 symptoms, 95% confidence interval 1.53 to 13.22 symptoms). This detrimental impact was reduced when combined with social interaction (mean difference –0.44 points, 95% confidence interval –4.39 to 3.52 points), but with no significant benefits for agitation. The exercise intervention significantly improved neuropsychiatric symptoms (mean difference –3.58 symptoms, 95% confidence interval –7.08 to –0.09 symptoms) but not depression (mean difference –1.21 points, 95% confidence interval –4.35 to 1.93 points). Qualitative work with care staff provided additional insights into the acceptability and feasibility of the intervention. Work package 4: optimisation of the WHELD programme led to a final version that combined person-centred care training with social interaction and pleasant activities. The intervention was adapted for delivery through a ‘champion’ model. Work package 5: a large-scale, multicentre randomised controlled trial in 69 care homes showed significant benefit to quality of life, agitation and overall neuropsychiatric symptoms, at reduced overall cost compared with treatment as usual. The intervention conferred a statistically significant improvement in quality of life (Dementia Quality of Life Scale – Proxy z-score of 2.82, mean difference 2.54, standard error of measurement 0.88, 95% confidence interval 0.81 to 4.28, Cohen’s d effect size of 0.24; p = 0.0042). There were also statistically significant benefits in agitation (Cohen-Mansfield Agitation Inventory z-score of 2.68, mean difference –4.27, standard error of measurement 1.59, 95% confidence interval –7.39 to –1.15, Cohen’s d effect size of 0.23; p = 0.0076) and overall neuropsychiatric symptoms (Neuropsychiatric Inventory – Nursing Home version z-score of 3.52, mean difference –4.55, standard error of measurement 1.28, 95% confidence interval –7.07 to –2.02, Cohen’s d of 0.30; p < 0.001). The WHELD programme contributed to significantly lower health and social care costs than treatment as usual (cost difference –£4740, 95% confidence interval –£6129 to –£3156). Focus groups were conducted with 47 staff up to 12 months after the end of work package 5, which demonstrated sustained benefits. Work package 6: the outputs of the programme were translated into general practitioner workshops and a British Medical Journal e-learning module, an updated national best practice guideline and a portfolio of lay and care home outreach activities.

Limitations

Residents with dementia were not involved in the qualitative work.

Conclusions

The WHELD programme is effective in improving quality of life and reducing both agitation and overall neuropsychiatric symptoms in people with dementia in care homes. It provides a structured training and support intervention for care staff, with lower overall costs for resident care than treatment as usual.

Future work

It will be important to consider the long-term sustainability of the WHELD programme and cost-effective means of long-term implementation.

Exploring pathways to Hospital Care for Patients with Alzheimer's disease and related dementias in rural South Western Uganda

BACKGROUND

In order to analyze use of health services and identify sources of delays in accessing the right care for patients with Alzheimer's disease and related dementias (AD/ADRD), understanding of care seeking pathways is needed. The objectives of this study were: (i) to explore pathways to hospital care for patients with AD/ADRD and (ii) to describe challenges experienced by the patients and their families while seeking health care.

METHODS

Using purposive sampling, 30-in-depth, semi-structured interviews were conducted among caregivers of older adults diagnosed with dementia from rural Southwestern, Uganda. Data was analyzed using ATLAS. Ti software.

RESULTS

There was variability in pathways to care from individual to individual. There was one broader theme captured: points of care choice with four broader categories: hospitals, clinics, places of religious worship and traditional healers' shrines, each with its facilitating factors, outcomes and challenges encountered. Most of the respondents reported use of hospitals at first and second visit to the health care point but places of religious worship became more common from third to sixth health care encounter. Major improvements (58.1%) were observed on hospital use but little or no help with prayers, clinics and traditional healers. The challenges experienced with formal points of care focused on lack and cost of prescribed drugs, weakening effect of the drugs, lack of skills to manage the condition, and lack of improvement in quality of life. These challenges together with knowledge gap about the disease and belief in spiritual healing facilitated the shift from formal to informal health care pathways, more particularly the places of religious worship.

CONCLUSIONS

Our study findings indicate that caregivers/families of patients with dementia went to different places both formal and informal care settings while seeking health care. However, hospital point of care was more frequent at initial health care visits while places of worship took the lead at subsequent visits. Although no specific pathway reported, most of them begin with hospital (formal) and end with non-formal. We recommend that health systems carry out public awareness on dementia.

Minor and subthreshold depressive disorders in Alzheimer's disease: A systematic review and meta-analysis of prevalence studies

BACKGROUND

Depressive symptoms are common in Alzheimer's disease (AD) and negatively impact patient well-being. The main aim of the present study was to establish summary estimates for the prevalence of minor depressive disorder (MinD) and subthreshold depression in AD and synthesise evidence on prognosis and management of these symptoms in order to inform clinical guidelines.

METHODS

Systematic review and meta-analysis of cross-sectional and longitudinal studies of prevalence, prognosis, and treatments for minor and subthreshold depression in AD. We searched MEDLINE, Embase, PsycINFO and CINAHL. We included studies that reported prevalence of subthreshold depressive disorders and those reporting data on validity of diagnostic criteria, mechanisms, or randomised controlled clinical trials (RCTs) testing effectiveness of interventions. Estimates of prevalence were pooled using random-effects meta-analyses. Two authors screened articles and independently extracted data on study characteristics.

RESULTS

We reviewed 5671 abstracts, retrieved 621 full text articles and included a total of 15 studies. Pooling data from 10 studies showed that prevalence for MinD in AD was 22.0% (95% CI 16.0 to 28.0). Prevalence for a clinical diagnosis of MinD (DSM-III-R and DSM-IV) was 26.0% (95% CI 20.0 to 32.0; 6 studies). People with MinD experienced higher levels of neuropsychiatric symptoms, functional and cognitive decline, although studies remain cross-sectional. Neither sertraline nor a carer intervention were effective in reducing symptoms.

CONCLUSION

This review finds that MinD is prevalent in people with a diagnosis of AD and requires clinical attention. Research is warranted to develop effective interventions to treat and prevent these symptoms.

Effect of Self-Efficacy on Quality of Life in People With Mild Cognitive Impairment and Mild Dementia: The Mediating Roles of Depression and Anxiety

OBJECTIVES

To examine the mediating effects of depression and anxiety in the relationship between self-efficacy and quality of life among people with mild cognitive impairment (MCI) or mild dementia.

METHOD

A total of 196 patients diagnosed with MCI or dementia due to Alzheimer disease completed structured measures of self-efficacy, quality of life, and depressive and anxiety symptoms. We examined direct and mediated effects by fitting structural equation models to data.

RESULTS

Our analyses supported that the effects of self-efficacy on quality of life may be partially mediated by depression and anxiety. Both anxiety and depression had significant mediating effects, with depression showing a stronger effect.

CONCLUSION

These results suggest that increased self-efficacy may have a positive effect on quality of life in people with MCI or dementia-partly by reducing depression and anxiety. These findings may have important practical implications for tailoring therapeutic interventions.

Behavioural activation treatment for depression in individuals with neurological conditions: a systematic review

OBJECTIVE

To evaluate the effectiveness of behavioural activation interventions for people with neurological conditions with comorbid depression, and explore content and adaptations.

DATA SOURCES

PsycINFO, MEDLINE, CINAHL, AMED, and EMBASE databases were searched on the 19 November 2019. Reference lists of selected full-texts were screened by title.

REVIEW METHODS

We included peer-reviewed studies published in English that used behavioural activation for treatment of depression in adults with a neurological condition. Single-case reports, reviews, and grey literature were excluded. Methodological quality was assessed by two authors independently, and quality was appraised using Critical Appraisal Skills Programme checklists.

RESULTS

From 2714 citations, 10 articles were included comprising 590 participants. Behavioural activation was used to treat depression in people with dementia (n = 4), stroke (n = 3), epilepsy (n = 1), Parkinson's disease (n = 1), and brain injury (n = 1). Sample size ranged from 4 to 105 participants. There were seven randomized controlled studies; however, no studies compared behavioural activation to an alternative psychological therapy. The effect sizes varied between small and large in the studies where effect size could be calculated (d = 0.24-1.7). Methodological quality of the included studies was variable. Intervention components were identifying and engaging in pleasurable activities, psychoeducation, and problem-solving. Adaptations included delivering sessions via telephone, delivering interventions via primary caregivers, and giving psychoeducation to caregivers.

CONCLUSION

The effectiveness of behavioural activation in randomized controlled trials varied from small to large (d = 0.24-1.7) in reducing depression. The content of behavioural activation was comparable to established treatment manuals. Adaptations appeared to support individuals to engage in therapy.

Diagnosing and Treating Depression in Patients with Alzheimer's Disease

Although cognitive and functional impairment are the hallmark features of Alzheimer's disease (AD), neuropsychiatric symptoms associated with AD account for increased rates of disability and profoundly impact the quality of life of both patients and their caregivers. This narrative review of current evidence provides practical guidance in diagnosing and managing depression in patients with AD using pharmacological and nonpharmacological interventions. After apathy, depression is the second most common neuropsychiatric symptom in AD. Diagnosing late-life depression (LLD), particularly in those affected by AD, is complicated because older patients may not meet the criteria for a major depressive disorder. Clinically, late-life depression and dementia can be indistinguishable. Although these two entities are now thought to be related, the pathologic mechanisms remain unclear. Evidence suggests that LLD may be a prodromal symptom of neurodegenerative disease. The various geropsychiatric measures currently used to diagnose, rate the severity of, and monitor the progress of treatment for depression are imperfect. Neuroimaging represents a promising avenue toward understanding the complex pathophysiologic relationships between dementia and LLD, and will support the pursuit of biomarker-driven diagnosis and treatment. Nonpharmacologic interventions to relieve depression in persons with cognitive impairment and dementia include emotion-oriented therapies, behavioral and cognitive-behavioral modification programs, and structured activity programs. Sensory-stimulation therapies and multisensory approaches show some promise for successfully treating depression in patients with dementia, but further rigorous research is needed to establish their validity. Clinical consensus and research appear to support selective serotonin reuptake inhibitors as a first choice for the pharmacological treatment of depression in patients with dementia. However, initial support for these therapies remains variable, and further investigation is needed. Extra care is required in prescribing to this population because of the generally high level of medical and psychiatric comorbidity and the potential difficulty in assessing the cognitively impaired patient's response.

Nonpharmacological Interventions for Anxiety and Dementia in Nursing Homes: A Systematic Review

Anxiety is a major mental disorder in later life that impacts on activities of daily living and quality of life for adults living with dementia in nursing homes. The aim of this article was to systematically review nonpharmacological interventions for older adults living in nursing homes who experience comorbid anxiety and dementia.

METHOD

A systematic literature search was conducted across key databases (Cinahl, ASSIA, Cochrane reviews and trials, psycARTICLES, psycINFO, and PubMed) to identify studies measuring anxiety as an outcome for an intervention for older adults living with dementia in nursing homes, up to December 31, 2017.

RESULTS

The search yielded a total of 1,925 articles with 45 articles accessed for full article review. A total of 13 articles were included in this review following quality appraisal based on Cochrane methodology with six different anxiety measures used. The studies included were moderate to high-quality randomized control trials although heterogeneity precluded a combined meta-analysis.

CLINICAL IMPLICATIONS

The most common interventions used to address anxiety in this population were music therapy and activity-based interventions although there was limited evidence for the efficacy of either intervention. Little is known about effective nonpharmacological treatment for anxiety for people living with dementia in nursing homes. Further research using consistent measurement tools and time points is required to identify effective interventions to improve the quality of life for people living with both dementia and anxiety in nursing homes.

Meta-analysis of psychosocial interventions for people with dementia and anxiety or depression

Objectives: Assess the effectiveness of psychosocial interventions for depression and anxiety in people with dementia (PWD) or mild cognitive impairment (MCI). Method: OvidMedline, PsychInfo and Embase were searched for studies on the 5^th August 2017. The efficacy of the studies was estimated using meta-analyses. Results: Eight RCTs were included. No RCTs were identified for people with MCI. Four RCTs found that psychosocial interventions (multicomponent intervention, Tai Chi, problem adaptation therapy and exercise/walking) were effective at reducing symptoms of depression in PWD who were depressed. One study (Tai Chi) found that these reductions were no longer evident at six-month follow-up. Another study, not included in the meta-analyses, found that pleasant events behaviour therapy and problem solving behaviour therapy improved depression symptoms and this effect remained significant at follow-up. Three RCTs found that psychosocial interventions (music therapy and cognitive behavioural therapy (CBT)) reduced symptoms of anxiety in PWD who were anxious. Evidence from two of these RCTs (music therapy and CBT) showed that these improvements were evident at three to six-month follow-up. Conclusion: The identified psychosocial interventions are effective at reducing symptoms of depression or anxiety in PWD experiencing these symptoms. This review is limited by the quality of studies, small sample sizes and the heterogeneity of the interventions, therefore high quality studies with larger sample sizes are required to test the efficacy of specific interventions such as CBT.

Dementia

Alzheimer disease (AD) and other dementia syndromes are becoming more common; an estimated 5.5 million adults aged 65 years or older are living with AD in the United States. It is important for primary care physicians to gain knowledge in this field because most community-dwelling older adults receive their care from them. This article discusses the latest findings in approaches to prevent cognitive decline as well as dementia screening, diagnosis, and treatment. Approaches to address quality of life for persons with dementia and their caregivers are also discussed.

Treatment fidelity evidence for BE-ACTIV - a behavioral intervention for depression in nursing homes

Objectives: Evidence-based depression therapies are difficult to implement in nursing homes. We present data for BE-ACTIV, a 10-week depression treatment designed for implementation in nursing homes, to address questions of treatment fidelity (delivery, receipt, and enactment) in that context. Method: Participants were 41 patients from 13 nursing homes in the treatment arm of a clinical trial, treated by graduate student therapists. Therapists and their supervisor rated their audio-recorded sessions for adherence to treatment protocol and session quality. Results: Delivery of core program elements averaged from 80-94% across all sessions; mean quality was 5.6 (SD 0.61) out of 6 points. Delivery of core components to nursing home activities staff who collaborated in the treatment was similarly high. Patients received an average of 7.32 sessions (SD 3.39); 17 completed 10 sessions. The theoretical basis of BE-ACTIV is behavioral activation; therapist-client dyads planned new pleasant events weekly, from a mean of 3.66 (SD 1.35) after the first session to a mean of between 5 and 6 activities a week across sessions 6-9, with a similar progression in percent activities completed. Activities enactment was significantly related to the likelihood of remission at post-treatment, and of maintaining improvement at 3-month follow-up. Treatment receipt and enactment were also related to improved mood from baseline to 3 months. Conclusion: Results demonstrate delivery, receipt, and successful enactment of BE-ACTIV core components in diverse nursing homes and patients, and support the theoretical premise of the intervention. These findings support further implementation work for the BE-ACTIV intervention.

High Caregiver Burden in Young Onset Dementia: What Factors Need Attention?

BACKGROUND

There is an increase in prevalence of young onset dementia (YOD). The specific problems among YOD patients and levels of caregiver burden (CB) in this group warrants further evaluation.

OBJECTIVE

To evaluate and compare level of CB in YOD and late onset dementia (LOD). Also, we sought to understand the specific factors, such as neuropsychiatric symptoms, that may affect the levels of caregiver burden in the YOD group.

METHODS

Patient-caregiver dyads with YOD and LOD were recruited from a tertiary neurology center. Levels of CB between YOD and LOD were compared among 183 patient-caregiver dyads. CB was quantified using the Zarit Burden Inventory (ZBI). Neuropsychological evaluations as well as the Neuropsychiatric Inventory were performed. Factors that influenced level of CB in YOD group was investigated with regression analyses.

RESULTS

There were 57 YOD and 126 LOD dyads. Caregivers of YOD subjects reported significantly higher levels of burden compared to caregivers of LOD subjects (ZBI: 17.3 versus 13.94; p = 0.015). 52.6% of YOD caregivers reported a high caregiver burden. When compared to caregivers of LOD, the odds of a caregiver of YOD reporting high caregiver burden was 2.34 (95% CI: 1.22-4.49: p = 0.010). YOD dyads with a high caregiver burden had significantly higher neuropsychiatric inventory scores. Risk factors for high caregiver burden in YOD included family history of dementia and behavioral symptoms including disinhibited behavior, delusions, and apathy.

CONCLUSION

Targeted support for caregivers of patients with YOD is needed to address the higher CB in this group.

Investigating the effect of multisensory stimulation on depression and anxiety of the elderly nursing home residents: A randomized controlled trial

PURPOSE

The aim was to determine the effect of multisensory stimulation (MSS) on the depression and anxiety status among nursing home-dwelling elderly people in Ahvaz, Iran.

DESIGN AND METHODS

This clinical trial study conducted on 28 old people living in nursing homes in Ahvaz, who were divided into two groups of intervention and control. The interventions included sensory stimulations of touch, sound, and sight for 4 weeks and 3 sessions weekly and 25 min per each session.

FINDINGS

The mean depression and anxiety scores of the intervention group before and after the intervention were 14.5 ± 5.5 and 10.1 ± 5.3 and, 9.6 ± 8.1 and 6.1 ± 6.2, respectively.

PRACTICE IMPLICATIONS

MSS could improve the condition of depression and anxiety in the elderly nursing home residents.

[Psychotherapy with mild cognitive impairment and dementia]

BACKGROUND

Despite evidence for psychotherapy (PT) in elderly patients, it is not standard care in patients with mild cognitive impairment and dementia. Although neuropsychiatric symptoms are frequent in these patients, there is a lack of studies investigating the importance and efficiency of PT.

OBJECTIVE

Can patients with mild cognitive impairment and dementia benefit from PT? If so, which modifications of therapeutic strategies are necessary for treating elderly patients with mild cognitive impairments?

MATERIAL AND METHODS

Evaluation of empirical evidence on the efficiency of PT for patients with mild cognitive impairment and dementia. Presentation of interventions and modifications of therapeutic strategies.

RESULTS

Empirical evidence points towards beneficial effects of PT on depressive symptoms and quality of life. The treatment of anxiety disorders has so far been broadly neglected. Modifications of therapeutic strategies include simplification of content, repetitions, implementation of external memory aids and inclusion of caregivers into therapeutic process.

CONCLUSION

Psychotherapy can be effective in patients with mild cognitive impairment and early stages of dementia. When practicing PT, an adaptation of therapeutic strategies is necessary. Nevertheless, there is a need for further studies investigating the benefits and implementation of PT into standard care, especially as pharmacological interventions are very limited in their efficiency and tolerability in this patient population.

Assessing implicit and explicit dementia stigma in young adults and care-workers

This aim of this study was to assess implicit and self-reported stigma towards people with dementia in young adults with no contact or experience ( n = 23), and in care-workers ( n = 17 professional dementia care-workers). Data were analysed to determine whether stigma was related to self-reported levels of depression, anxiety, stress and professional burnout. Forty participants completed the Implicit Relational Assessment Procedure and Dementia Attitudes Scale. The Depression Anxiety and Stress Scale and Maslach Burnout Inventory were used to measure depression, anxiety, stress and professional burnout. The young adult group showed statistically significant levels of dementia stigma (on the two “ dementia” trial-types, p = .027 and p = .030). Statistical analyses showed more dementia-positive attitudes in care-workers compared to young adults on the Implicit Relational Assessment Procedure and the Dementia Attitudes Scale (both p’s=.021). Spearman’s Rho correlations tests showed that for the care-givers, higher levels of burn-out were associated with more negative attitudes towards people with dementia on both of the Dementia Attitudes Scale subscales (social comfort p<.001 and dementia knowledge p=.005). The results support prior research showing that experience with a stigmatised group can lower stigma and demonstrate the importance of providing a supportive work environment to mitigate burnout.

Working mechanisms of dyadic, psychosocial, activating interventions for people with dementia and informal caregivers: a qualitative study

Background

People living with dementia (PWD) and their informal caregivers often report difficulties in maintaining their usual activities. Several dyadic, psychosocial, activating interventions were developed to create insight into how to cope with limitations in a practical way and to increase skills for maintaining personal activities. Effects of these interventions varied so far. More knowledge on the working mechanisms of activating interventions might help to increase their impact. This study will provide more insights into the working mechanisms of three dyadic, psychosocial, activating interventions as the participating PWD, caregivers, and coaches perceived them during the interventions.

Participants and methods

We used a qualitative design with semi-structured interviews of 34 dyads that included 27 PWD, 34 caregivers, and 19 coaches. The data were analyzed with the constant comparative method.

Results

Many PWD and caregivers found capacity-building approaches beneficial. We identified “empowerment” as the core theme. Three working mechanisms explained why the interventions were perceived as having a beneficial impact: 1) enabling activities without providing false hope; 2) exploring the most important personal activity needs of the PWD and caregivers; and 3) a solution-focused approach to adapt, test, and practice activities. An individualized approach contributed to positive change.

Conclusion

For the overarching working mechanism empowerment, expertise in the field of dementia and psychological skills of coaches seem to be important. Assessing the needs, capacities, and limitations of both the PWD and the caregivers to take part in activities seems to be key, as well as the communication about it and the skills to teach a solution-focused approach. Studies on the impact of psychosocial and activating interventions might benefit from considering outcome measures directed at empowerment, along with aspects such as hope and belief in one’s own capacities versus traditional outcome measures as mood, burden, or quality of life.

Predictors of treatment outcome and attrition in adults with hoarding disorder

While a number of hoarding disorder-specific therapeutic interventions have been developed over recent years, hoarding disorder (HD) remains difficult to treat. The purpose of this investigation is to inform HD treatment efforts by examining factors that influence treatment attrition and treatment response. Secondary data analysis of baseline and post-treatment data from two previously published psychotherapy treatment studies for hoarding were performed to identify predictors of hoarding symptom improvement and treatment attrition in 106 adults with HD. No demographic variables were associated with symptom improvement or treatment attrition. However, higher levels of avoidant coping (i.e., self-distraction combined with behavioral disengagement) significantly predicted symptom improvement. The maintenance stage of change along with high readiness for change also significantly predicted symptom improvement. Participants who dropped from treatment had significantly higher baseline levels of denial and clutter, both of which independently predicted treatment attrition. The findings from this study suggest that emotion-related constructs, such as managing stress and motivation for change, may play an important role in patients' response to and participation in HD treatment.

Iterating a framework for the prevention of caregiver depression in dementia: a multi-method approach

ABSTRACTBackground:Dementia caregiving is often stressful and depression in family caregivers is not uncommon. As caregiver depression can have significant effects, there is a need for preventive efforts which are consistent with the extensive literature. We sought to consolidate the wide range of evidence (using a multi-method approach) into a simple framework that can guide the prevention of caregiver depression.

METHODS

Using multiple logistic regression, we derived the predictors of caregiver depression from an empirical dataset containing key information and depression scores (based on the Center-for-Epidemiological-Studies-Depression-Scale) of 394 family caregivers. We then chose an underpinning theory as the foundation of the framework, and conducted an umbrella systematic review to find possible links between the derived predictors and the theory. Last, we compared the iterated framework with known interventions for caregiver depression in recent literature to assess whether the framework could map meaningfully with the known interventions.

RESULTS

Significant predictors of caregiver depression included primary caregiver (odds ratio, OR = 1.53), severe dementia (OR = 1.40), and behavioral problems (OR = 3.23), lower education (OR = 1.77), and spousal caregivers (OR = 1.98). The integrated framework derived focuses on four strategic areas: physical-care demands of persons with dementia (PWD), behavioral problems of PWD, caregiving competency, and loss and grief of caregivers. This framework is supported by known interventions for caregiver depression in recent literature.

CONCLUSIONS

By consolidating a broad range of evidence, we iterated a framework to aid the understanding and prevention of caregiver depression in dementia. The framework offers an approach to prevention which is simple, systematic, and reflective of the extensive literature.

Reappraising the Efficacy and Acceptability of Multicomponent Interventions for Caregiver Depression in Dementia: The Utility of Network Meta-Analysis

Background

Previous meta-analyses have demonstrated the efficacy of interventions for caregiver depression in dementia. However, they generally lumped the interventions together without accounting for the multicomponent nature of most interventions. It is unknown which combination of components contributed to the efficacy and should be implemented in clinical practice.

Objectives

To reappraise the interventions for caregiver depression from a recent systematic review, and evaluate whether a network meta-analytic approach offers additional insight into the efficacy and acceptability of multicomponent interventions.

Research Design and Methods

This study built upon a recent systematic review which identified 33 RCTs on caregiver depression from multiple databases (Medline, EMBASE, CENTRAL, PsycINFO, PSYNDEX). The 33 RCTs had different combinations of components serving at least one of the three key functions: addressing the care needs of persons with dementia (“CN”), addressing caregiving competency (“CC”), and providing emotional support for loss and grief (“ES”). A Bayesian network meta-analysis was conducted to compare the efficacy and all-cause attrition across different combinations of interventions.

Results

CN–CC combination was significantly more efficacious than treatment-as-usual (standardized mean difference in depression scores, SMD = −0.25, 95% credible interval [CrI] = −0.41 to −0.08) and marginally better than CN (SMD = −0.43, 95% CrI = −0.85 to −0.00). While none of the interventions clearly had both high efficacy and acceptability, three combinations of interventions (CC, CN–CC, and CN–CC–ES) had a reasonable balance between efficacy and acceptability.

Discussion and Implications

Although interventions for caregiver depression in dementia are effective in general, the different components of interventions may not share the same efficacy and acceptability. In implementing interventions, policymakers may consider addressing CC first, introducing CN in a graded manner, and providing ES only when indicated. Future studies may also consider using network meta-analysis to gain additional insights on how to implement multicomponent interventions in geriatric care.
