Non-pharmacological interventions in dementia

Social robot PIO intervention for improving cognitive function and depression in older adults with mild to moderate dementia in day care centers: A randomized controlled trial

The increases in the older population, the prevalence of dementia, and the resulting social costs are burdensome to individuals, families, and the nation. This study examines whether the social robot PIO program intervention is effective for cognitive function and depression for older adults with mild to moderate dementia using two daycare centers in Daegu, Korea. Older adults with mild to moderate dementia and using a daycare center were included in the experimental (n = 33) and control (n = 33) groups. The experimental group participated in the social robot PIO program twice a week, 12 sessions, 50 minutes day for 6 weeks, and the control group received the usual care. From October 2022 through December 2022, a total 66 participants were included. Results showed that the cognitive function of the experimental group increased by 3.9±3.66, from 18.1±4.54 before intervention to 21.9±5.17 after intervention; the control group increased by 0.1±4.13, from 18.2±4.91 before intervention to 18.2± 4.77 after intervention. The difference between the two groups was statistically significant (t = 3.94, p<.001). Depression decreased -0.7±3.48 in the experimental group, from 5.9±4.74 before intervention to 5.2±4.65 after intervention, and decreased by -0.2±3.42, from 6.5±4.69 before intervention to 6.4±4.08 after intervention, in the control group, but the difference between the two groups was not statistically significant (z = -0.59, p =.557). It was confirmed that the social robot PIO program is effective in improving cognitive function in older people with mild to moderate dementia who use daycare centers. Therefore, it is recommended to periodically implement this program for the older adults who use daycare centers to improve cognitive function. The experimental group had lower depression than did those in the control group, but the effect is not statistically significant, so additional research is required.

Prescription of Nonpharmacologic Interventions in Memory Clinics: Data from the Clinical Pathway for Alzheimer's Disease in China (CPAD) Study

OBJECTIVES

Nonpharmacologic interventions are recommended to improve outcomes in dementia. Little is known about their prescription in practice, especially in non-Western populations. We investigated individual- and institution-level characteristics associated with nonpharmacologic interventions prescription in China.

DESIGN

A multicenter observational study.

SETTING AND PARTICIPANTS

This study used cross-sectional data from 889 community-dwelling outpatients living with dementia aged ≥45 years from a multicenter registry of 28 memory clinics in China.

METHODS

Prescription records of nonpharmacologic interventions, carer and clinic characteristics, and reasons for declining interventions were collected. Multilevel logistic regression was used to identify factors associated with the prescription.

RESULTS

Nonpharmacologic interventions were prescribed in 323 people (36.3%) with mild cognitive impairment or dementia. Cognitive activities and carer training/support were the most prescribed interventions. Multilevel logistic regression showed that 73% of the variance in prescription was attributed to institutional characteristics of the memory clinic. Greater caregiving gain [odds ratio (OR), 1.05; 95% CI, 1.02-1.09], lower burden (OR, 0.97; 95% CI, 0.95-1.00), worse carer-perceived dyad relationship (OR, 0.83; 95% CI, 0.70-0.99), and family history of dementia (OR, 2.08; 95% CI, 1.19-3.65) were individual-level factors associated with prescription. Among 440 people considered having a need but received no prescription, declined by user/carer was the main reason for not prescribing (70.7%). Skepticism about effectiveness by physicians/carers and carers being unable or lacking resources to use the interventions were the common reasons given.

CONCLUSIONS AND IMPLICATIONS

A relatively low prescription rate of nonpharmacologic interventions is related to both individual- and institution-level factors. Carer support and education, instrumental support, and prescription guidelines across specialties and sites are possible strategies to improve access to nonpharmacologic interventions in dementia care.

Language Learning for People Living with Dementia and Their Caregivers: Feasibility and the Quality of Experience

BACKGROUND

A body of research from around the world has reported positive effects of bilingualism on cognitive ageing and dementia. However, little is known about whether foreign language learning could be applied as an intervention for people already living with dementia. Yet, before it is possible to determine the efficacy of language courses as an intervention for people living with dementia (PLWD), it is necessary to establish whether such an intervention is feasible. Our study explored this possibility.

METHODS

We conducted an exploratory study to examine the feasibility and tolerability of 2-week Italian beginner courses for PLWD in early stages and their family carers in two Scottish Dementia Resource Centres (DRCs). The courses were delivered by trained tutors from Lingo Flamingo, a social enterprise specialising in language teaching for older learners and learners with dementia. Twelve PLWD and seven carers participated in the study. Focus groups preceded and followed the courses. Additional post-course open interviews with the DRC managers were conducted, with a follow-up via telephone approximately one year later.

RESULTS

Qualitative content analysis resulted in 12 themes, 5 reflected in the interview schedule and 7 arising from the focus groups and interviews. Overall, the courses were perceived positively by PLWD, carers, and DRC managers, although a few logistically and linguistically challenging aspects were also mentioned. The courses were found to positively impact both the individual by increasing self-esteem and producing a sense of accomplishment as well as the group by creating a sense of community. Notably, no adverse effects (in particular no confusion or frustration) were reported.

CONCLUSION

The positive outcomes of our study open a novel avenue for future research to explore foreign language training in dementia as an intervention and its implications.

A systematic review of psychosocial interventions for people with intellectual disabilities and dementia

OBJECTIVES

As the life expectancy of individuals with intellectual disabilities (ID) continues to increase, there is an increased risk of developing dementia. While psychosocial interventions are gaining prominence, evidence is limited for people with both dementia and ID. This review discusses the effectiveness of direct psychosocial interventions and adaptations to facilitate delivery within this population.

METHODS

The review followed the PRISMA guidelines. Five electronic databases, grey literature, and reference lists of included articles were searched for relevant studies. 10 eligible studies were appraised and analysed by narrative synthesis.

RESULTS

Ten distinct interventions were identified and categorised based on their purpose and delivery. All interventions were beneficial in improving a range of outcomes, though some studies were of low quality and most had small samples. Common adaptations included simplification of tasks and material, higher staff-to-client ratio, and alternative communication methods.

CONCLUSION

There is emerging evidence for several psychosocial interventions for people with ID and dementia, though further research is required on effectiveness and generalisability. The adaptations discussed may guide implementation into routine care and contribute to current policies and guidelines on improving ID and dementia care.

Mobile app-based interventions to improve the well-being of people with dementia: a systematic literature review

As the global aging trend increases, dementia pressures families and society. Mobile apps that provide interventions and independence for people with dementia (PwD) may relieve this pressure. This study reviews mobile app-based interventions designed for use with PwD, focusing on the type, design, and evaluation of mobile apps. This study searched PubMed, Web of Science, SpringerLink, Taylor & Francis, and IEEE Xplore databases for mobile applications designed for people with disabilities and reported the evaluation results. This study aimed to find out what types of mobile apps developed for people with dementia were marketed during the COVID-19 pandemic, to find out what relevant studies have been done to evaluate mobile apps, and whether users have benefited. Twenty papers were eligible, covering four different intervention types and assessment methods. This review found that Serious games can improve the cognitive abilities of PwD and contribute to the mental recovery of patients. Recall therapy and musical mobile apps help PwD slow down memory loss. Personal life mobile apps are effective in assisting PwD to improve independent living.

The impact of music listening intervention on Asia elderly with dementia: a systematic review

From an initial pool of 2303 studies, ten eligible and potential studies were selected through rigor inclusion and exclusion criteria for this systematic review to examine music therapy's effect on dementia. The review included 967 participants, with the majority being female. A significant number of studies were conducted in Taiwan. Although several cognitive ability assessment methods were employed in the selected studies, the Mini-Mental State Examination (MMSE) was the most commonly used tool for evaluating the effects of music therapy on dementia. Overall, the current review demonstrates that music therapy can be a valuable strategy for treating patients with dementia, with its outcomes including improved cognitive function and potentially slowing the progression of the disease's severity. Therefore, this study can significantly contribute to future studies and practices aimed at using music therapy to treat dementia.

Factors Affecting Physical Activity in People with Dementia: A Systematic Review and Narrative Synthesis

Physical activity (PA) has positive effects on the physical and cognitive functioning of people with dementia. Knowledge about what limits and stimulates people with dementia to participate in PA is essential to promote effective PA implementation and enhance PA levels. Previous reviews primarily included opinion-based studies, using data from interviews, focus groups or dyads. By including implementation studies, we aimed to elaborate on previous reviews by identifying new barriers to PA and new facilitators and motivators for PA. We conducted systematic searches in Pubmed, PsychInfo and Web of Science for studies published up to the 21st of September 2021. Search terms were related to the population of people with dementia, PA interventions and implementation outcomes. Studies were included if PA participation was investigated during actual PA implementation. No restrictions were made regarding study design, date of publication, PA type or outcome measures. Studies not implementing PA or not evaluating the implementation were excluded. Based on 13 empirical studies, we identified 35 barriers, 19 facilitators and 12 motivators. Of these, 21 barriers, 11 facilitators and 4 motivators were not identified by previous reviews. New factors are related to the support for people with dementia from informal and formal caregivers, e.g., revealing the importance of a trusting relationship. Furthermore, support for staff from the institution or an external party is needed to overcome doubts about PA, for example, related to safety and effects. New factors also suggested specific recommendations for the content and organization of the PA intervention, for instance, related to how to give instructions. Overall, factors affecting PA identified with opinion-based or implementation studies are complementary. Our extended overview shows the complexity of PA implementation and may help to personalize PA, develop implementation strategies, facilitate actual PA implementation and free up resources needed for effective implementation.

Pharmacogenomics of Dementia: Personalizing the Treatment of Cognitive and Neuropsychiatric Symptoms

Dementia is a syndrome of global and progressive deterioration of cognitive skills, especially memory, learning, abstract thinking, and orientation, usually affecting the elderly. The most common forms are Alzheimer's disease, vascular dementia, and other (frontotemporal, Lewy body disease) dementias. The etiology of these multifactorial disorders involves complex interactions of various environmental and (epi)genetic factors and requires multiple forms of pharmacological intervention, including anti-dementia drugs for cognitive impairment, antidepressants, antipsychotics, anxiolytics and sedatives for behavioral and psychological symptoms of dementia, and other drugs for comorbid disorders. The pharmacotherapy of dementia patients has been characterized by a significant interindividual variability in drug response and the development of adverse drug effects. The therapeutic response to currently available drugs is partially effective in only some individuals, with side effects, drug interactions, intolerance, and non-compliance occurring in the majority of dementia patients. Therefore, understanding the genetic basis of a patient's response to pharmacotherapy might help clinicians select the most effective treatment for dementia while minimizing the likelihood of adverse reactions and drug interactions. Recent advances in pharmacogenomics may contribute to the individualization and optimization of dementia pharmacotherapy by increasing its efficacy and safety via a prediction of clinical outcomes. Thus, it can significantly improve the quality of life in dementia patients.

Life Story Book to enhance communication in persons with dementia: A systematic review of reviews

The Life Story Book has been commonly used in promoting person-centred care in older adults, especially for persons with dementia. This involves collecting the life stories and memories of the person living with dementia and compiling them into a book or folder, which is used by staff or family to assist the person recall these memories. Evidence on the use, benefits and influences of the Life Story Book in dementia care is limited. This systematic literature review aimed to collect past reviews and provide a thorough overview of the use, benefits, and impact of the Life Story Book for the person with dementia, the relatives, family, and caregivers. The electronic databases PubMed, Scopus, Science Direct and Web of Science as well as grey literature through Google Scholar were searched to select the relevant studies. Seven studies that meet the inclusion criteria were selected and data synthesised. Findings revealed that the use of the Life Story Book has no specific guidelines and has been described with numerous characteristics and varied implementation methods. The Life Story Book intervention is found to provide positive outcomes for the person with dementia and the carers involved. Six out of the seven studies reported that Life Story Book enhanced communication between persons with dementia, relatives, care staff, and residents. The review extends the current evidence on the usage of the Life Story Book in dementia care and confirms that the use of life stories leads to better care in various settings. However, more research is needed to reveal the potential of the Life Story Book in enhancing communication. Guidelines and training are also required to make the best use of the Life Story Book.

Symptom-specific non-pharmacological interventions for behavioural and psychological symptoms of dementia: protocol of an umbrella review of systematic reviews of randomised controlled trials

INTRODUCTION

There are various non-pharmacological interventions for dementia care. However, healthcare providers continue to face challenges in determining the most suitable interventions for the behavioural and psychological symptoms of dementia (BPSD), which vary according to individuals. This umbrella review aims to identify and summarise the effective non-pharmacological interventions for each sub-symptom to provide individualised, evidence-based recommendations for clinical practice.

METHODS AND ANALYSIS

This review follows the guideline of the Cochrane methodology for umbrella reviews. It focuses only on systematic reviews (SRs) with or without a meta-analysis of randomised controlled trials. Five electronic databases: PubMed, Cumulative Index to Nursing and Allied Health Literature, Embase, PsycINFO and Cochrane Database, will be searched. The screened SRs will be determined for eligibility by the PICO formulation: (Population) older adults with dementia of any type; (Intervention) all types of non-pharmacological intervention; (Comparison) usual care or other non-pharmacological intervention; and (Outcome) BPSD and its sub-symptoms. The quality of the individual SRs will be appraised using A Measurement Tool to Assess Systematic Reviews 2. The overlap of primary studies will also be considered by eliminating an old-date SR conducted by the same authors with the same interest and calculating the Corrected Covered Area. Data will be extracted according to the pre-determined formula, which will organise non-pharmacological interventions according to the sub-symptoms of BPSD and not according to the type of intervention.

ETHICS AND DISSEMINATION

Since this is a review paper, ethical approval is not required. The findings of this review will be disseminated through publication in a peer-reviewed journal.

Characteristics of Cognitive Function Changes and Related Factors in Individuals With Cognitive Impairment During the Pandemic of COVID-19: A Retrospective Chart Review Study

OBJECTIVE

This study aimed to explore the characteristics and factors related to changes in cognitive function in vulnerable individuals with cognitive impairment during the coronavirus disease 2019 (COVID-19) pandemic.

METHODS

Among patients who visited a local university hospital with subjective cognitive complaints, those who had been tested for cognitive function at least once after the onset of COVID-19 and tested regularly at least three times within the last 5 years were included (1st, the initial screening; 2nd, the test immediately before the COVID-19 pandemic; 3rd, the most recent test after the pandemic). Finally, 108 patients were included in this study. They were divided into groups according to whether the Clinical Dementia Rating (CDR) was maintained/improved and deteriorated. We investigated the characteristics of the changes in cognitive function and related factors during COVID-19.

RESULTS

When comparing CDR changes before and after COVID-19, there was no significant difference between the two groups (p=0.317). Alternatively, the main effect of the time when the test was conducted was significant (p<0.001). There was also a significant difference in the interaction between the groups and time. When the effect of the interaction was analyzed, the CDR score of the maintained/ improved group significantly decreased before COVID-19 (1st-2nd) (p=0.045). After COVID-19 (2nd-3rd), the CDR score of the deteriorated group was significantly higher than that of the maintained/improved group (p<0.001). Mini-Mental State Examination recall memory and changes in activity during COVID-19 were significantly associated with CDR deterioration.

CONCLUSION

Memory dysfunction and decreased activity during the COVID-19 pandemic are strongly related to the deterioration of cognitive impairment.

The Neuropathological Impacts of COVID-19: Challenges and Alternative Treatment Options for Alzheimer's Like Brain Changes on Severely SARS-CoV-2 Infected Patients

Recently, some researchers claimed neuropathological changes lead to Alzheimer's-like brains after severe infection of SARS-CoV-2. Several mechanisms have been postulated on how SARS-CoV-2 neurological damage leads to Alzheimer's disease (AD) development. Neurobiochemical changes during infection may significantly induce Alzheimer's disease in severely COVID-19 infected people. The immune system is also compromised while infected by this novel coronavirus. However, recent studies are insufficient to conclude the relationship between Alzheimer's disease and COVID-19. This review demonstrates the possible pathways of neuropathological changes induced by the SARS-CoV-2 virus in AD patients or leading to AD in COVID-19 patients. Therefore, this study delineates the challenges for COVID-19 infected AD patients and the mechanism of actions of natural compounds and alternative treatments to overcome those. Furthermore, animal studies and a large cohort of COVID-19 survivors who showed neuroinflammation and neurological changes may augment the research to discover the relationship between Alzheimer's disease and COVID-19.

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

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

Napping and cognitive decline: a systematic review and meta-analysis of observational studies

BACKGROUND

No clear evidence is available for the influence of napping on cognitive function in older adults. This systematic review and meta-analysis aimed to elucidate the cross-sectional and longitudinal relationships between napping and cognitive function (global cognition and memory) and to explore whether some individual characteristics and sleep characteristics can modify this relationship.

METHODS

We systematically searched Medline (via PubMed), Web of Science, and Scopus. DerSimonian and Lair and Hartung-Knapp-Sidik-Jonkman random effects methods were used to compute pooled estimates of odds ratios (ORs) and their respective 95% confidence intervals (95% CIs) for the association of global cognition and memory with napping. The mean age, the night sleep time (hours), and the percentage of women, no nappers, and people in the less night-time sleep duration category were used for meta-regressions.

RESULTS

Twenty-five studies were included in this systematic review and meta-analysis, 18 cross-sectional and seven longitudinal studies, including 95,719 participants older than 60 years. The pooled ORs from the cross-sectional analyses were 1.03 (95% CI: 1.01 to 1.06) for global cognition and 1.06 (95%: 0.90 to 1.26) for memory. The pooled ORs from the longitudinal analyses were 1.00 (95% 0.85 to 1.18) for global cognition and 1.08 (95% 0.98 to 1.19) for memory. These associations were not modified by individual or sleep characteristics.

CONCLUSION

Our data confirm the absence of association between napping and global cognition and memory regardless of the characteristics of the population. This information might be considered when providing lifestyle recommendations to adults with and without cognitive complaints.

Responses and Interventions to Delusions Experienced by Community-Dwelling Older Persons With Dementia

We examined how family caregivers react, and what interventions they use in response to delusions exhibited by relatives with dementia in a community setting. Structured interviews were conducted with 68 family caregivers whose relatives were described as experiencing delusions based on the BEHAVE-AD or the NPI. Quantitatively, we cross-tabulated the type of response to delusion by the type of person providing the response and by the type of delusion manifested. Qualitatively, we analyzed open-ended responses to understand the types of caregivers' responses to delusions, the contextual circumstances, and the impact of the responses. Caregiver responses to delusions included "Explaining that the delusion was wrong" (34% of responses), "Trying to calm down" (27%), "Agreeing with the delusion" (13%), "Distracting" (12%), and "Ignoring" (10%). Responses including "Anger, yelling or scolding," were rare. The vast majority of reactions were by family caregivers of the persons with dementia. The relative frequency of the type of reaction tended to be consistent across delusion types. The qualitative analyses added some categories of reactions, but mostly highlighted issues to be considered when examining responses and their efficacy, including the use of multiple responses, and the manner and mood in which responses are conveyed. To cope with delusions, family caregivers develop intuitive intervention techniques. Understanding those interventions and reactions by caregivers and their relative efficacy can inform guidance programs for family caregivers. Improved support for family caregivers has the potential to positively influence the behavior of caregivers and older adults with dementia and improve their respective quality of life.

The National Partnership to Improve Dementia Care and Hospital Readmission Among Skilled Nursing Facility Residents

The National Partnership to Improve Dementia Care in Nursing Homes (i.e., the National Partnership) was launched in March 2012. Using national Medicare, Minimum Data Set, and Nursing Home Compare data in CY 2010-2014, we examined changes in hospital readmissions for older post-acute skilled nursing facility (SNF) residents with Alzheimer's disease or related dementias (ADRD) following the National Partnership. Using residents without ADRD as reference group to control for concurrent policy and SNF quality changes, we estimated linear probability models to examine the relationship between readmissions and the National Partnership for residents with ADRD, and also stratified the analysis by quality of SNFs. We found a decreasing trend in hospital readmissions over time. The risk of readmissions in residents with ADRD decreased additional 0.3 percentage-points (p < .01) after the launch of the National Partnership. This relationship varied across SNFs with different quality, as it was stronger in high-quality compared to low-quality SNFs.

Study on Associating Emotions in Verbal Reactions to Facial Expressions in Dementia

The purpose of this study was to provide basic data on cognitive therapy and to improve social support programs for the elderly with dementia by identifying the difficulties they experienced in emotional communication by identifying how they recognized emotions in verbal reactions to facial expressions using Ekman’s photographs of facial expressions and comparing their responses with the general elderly population. There were 141 participants in this study. Data collection was conducted from 3 April 2019 to 30 June 2019 in Seoul, in the Gyeonggi-do and Gangwon-do provinces of South Korea. This study performed descriptive research in which subjects made participative decisions with their guardian through recruitment. The tools used in this study included a general characteristic questionnaire and the Ekman 6 facial expressions photographs tool, which underwent intensive validity studies. The collected data were analyzed using the R version 3.5.1 statistic computing platform. The ability of the elderly with dementia to associate verbal expressions with facial expressions differed from that of the general elderly population. The rates of correct associations of verbal expressions to facial expressions were similar across dementia grades. There was a significant difference in the proportion of correct associations between positive and negative emotions in the elderly with dementia compared to the general elderly population. In the elderly with dementia, pictures showing fear, anger, and disgust had higher wrong rates of incorrect answers than correct answers. The average score of elderly with dementia in associating verbal expressions with six facial expressions was 2.69, which was even lower when they were asked to associate verbal expressions with pictures showing facial expressions of anger or disgust. This study shows that elderly persons with dementia have difficulties identifying two negative emotions (anger, disgust) and find it much easier to identify a positive emotion of happiness represented by a smiling face. Since the ability of the elderly with dementia to interpret verbal expressions to facial expressions was different from that of the general elderly population, careful attention and consideration are needed to support and communicate emotions to the elderly with dementia.

A Brief Report on Reviews of Existing Creative Art-Based Interventions in Dementia Care From 2010-2020

The following brief report provides an overview of previously published reviews in the context of creative arts-based interventions for persons with dementia. A total of 22 review articles were identified and summarized. Next steps are suggested for future studies that may wish to a) develop a new review, or b) create new studies filling in the gaps identified by the authors in this report.

Providing music therapy for people with dementia in an acute mental health setting

As global figures for dementia are set to rise significantly, there has been a shift towards using non-pharmacological interventions such as music therapy to enhance the quality of life for people with the condition. Research into music therapy interventions for this patient group in acute mental health inpatient settings, however, is limited. This article describes a service evaluation that explored whether group music therapy was effective for people with dementia in such settings. Open group music therapy sessions were hosted weekly in two acute wards and the researchers examined the social and behavioural outcomes of participants pre and post-intervention. The results indicated that music therapy significantly improved patient outcomes following participation. The outcome measure developed for this service evaluation was found to be a reliable tool for measuring the effectiveness of music therapy on patient outcomes.

Mind-body therapies for older adults with dementia: a systematic review and meta-analysis

PURPOSE

This systematic review of randomised controlled trials (RCTs) aimed to determine the effects of mind-body therapies (MBTs) among older adults with dementia.

METHODS

We searched five electronic databases (PubMed, PsycINFO, Web of Science, EMBASE, and the Cochrane Library) for publications investigating the effect of MBTs until July 14th, 2020. We included published peer-reviewed RCTs among participants with a mean age of 60 and above and a diagnosis of any dementia. Eligible studies included measurements for all types of health outcomes, including cognitive function, neuropsychiatric inventory, depressive syndromes, agitation, psychosocial status, and other health outcomes. Two investigators extracted data, the risk of bias for each study was evaluated through Review Manager, and statistical meta-analysis was performed using Stata.

RESULTS

A total of nine studies met the eligibility criteria, with full-text available for systematic review. Five of them, with 338 participants, were included in the meta-analysis. For most included RCTs of the review, the methodological quality was moderate. The meta-analysis showed that Tai Chi had a mild effect on global cognitive function (Mini-Mental State Examination, SMD = 0.40, 95% CI 0.10-0.70). Yoga and aromatherapy may also be beneficial for depression, and these three MBTs improved quality of life.

CONCLUSION

The current review suggested that MBTs may act as potential non-pharmaceutical approaches to improve certain health outcomes among older populations with dementia. Systematic review and meta-analysis registration: PROSPERO CRD42021198514.

Impact of Digital Device, Exercise, and Music Intervention Programs on the Cognition and Depression of the Elderly in South Korea: A Meta-Regression Analysis

Background: This study examined the effect of digital devices, exercise, and music intervention programs for the elderly in Korea on their cognition and depression. Methods: This study selected 70 cognition programs and 46 depression programs for the elderly in Korea. This study controlled the characteristics of the programs and participants, and conducted a meta-regression analysis to estimate the intervention effect size of digital devices, exercise, and music on cognition and depression. Results: The meta-regression analysis revealed that digital device programs had a smaller effect size with respect to the improvement of cognitive functions than programs that did not use digital devices. The exercise programs had a small effect size on depression, but their effect size on cognition was not significantly different. Discussion: These findings provide implications for developing a program that combines music therapy with digital devices and exercise interventions, which can be effective in addressing both cognition and depression.

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

This paper assesses the effectiveness of reminiscence therapy (RT) in people with mild to moderate dementia in long-term care facilities. A literature search was conducted in CINAHL, MEDLINE, PsychINFO, and Embase from inception to December 2020. Five RCTs with 267 participants were included; two were meta-analysed. Cochrane collaboration's risk of bias tool was used to evaluate the methodological quality of the included RCTs, and the risk of bias across studies was assessed using the GRADE method. The overall quality of evidence was moderate to low. Among the five trials, none measured the efficacy of RT on agitation. Reminiscence therapy was effective in reducing depression and improving autobiographical memory, but its effects were inconsistent. There was a significant improvement in quality of life (QoL) following RT. The meta-analysis showed no statistical significance on the pre-post intervention differences in depression (SMD -0.28, 95%CI -0.91-0.35, p > 0.05) and autobiographical memory scores (SMD 0.57, 95%CI -0.07-1.21, p > 0.05). Reminiscence therapy may have some benefits in reducing depression and improving the QoL and cognition in this population; however, its effectiveness should be tested further.

The effect of individual reminiscence therapy on adaptation difficulties of the elderly: a randomized clinical trial

BACKGROUND

Reminiscence therapy is one of various interventions that can be made to protect and improve the mental health of the elderly. The aim of this study was to evaluate the effect of individual reminiscence therapy given during home visits on adaptation difficulties.

METHOD

This was a randomized controlled, single-blind study designed with a pretest-post-test and follow-up pattern. We divided the participants, 65 elderly people living in Isparta, Turkey, by simple randomization into intervention (31) and control (34) groups. Individual reminiscence therapy was applied to the intervention group participants for eight weeks during house visits once a week. The weekly topics of the reminiscence therapy included childhood, business life, married life, old items, holidays, traditional dishes, and songs and movies, and were all culture-specific. No intervention was applied to the control group. Study data were collected by using a Sociodemographic Data Form created by the researchers, the Assessment Scale of Adaptation Difficulty for the Elderly (ASADE), and the Nurses' Observation Scale for Geriatric Patients (NOSGER). Pretest, post-test, and follow-up data were collected at the individuals' homes in face-to-face interviews.

RESULTS

After the eight-week course of reminiscence therapy, there was a significant decrease in the ASADE mean score for the intervention group (P = 0.003) and a significant increase for the control group (P < 0.001). Significant increases were also found in the mean NOSGER scores for the intervention (P = 0.039) and control (P < 0.001) groups; however, the score increase was higher for the control than for the intervention group. Also, there was a significant difference in the ASADE (P < 0,001) and NOSGER (P = 0.01) mean scores of the intervention and control groups.

CONCLUSION

This study found that individual reminiscence therapy decreased adaptation difficulties in the elderly.

An Innovative Non-Pharmacologic Treatment for Delusional Misidentification in Persons with Major Neurocognitive Disorder

Misidentification delusions are false, fixed beliefs that assign an incorrect identity to a previously familiar or unfamiliar person or place. Such delusions are common in several neuropsychiatric disorders and place a particular burden on individuals with Major Neurocognitive Disorder and their caregivers. No standard pharmacologic or non-pharmacologic treatment approaches have been shown to be consistently effective in addressing this problem. We describe two caregiver-care recipient dyads in which an innovative non-pharmacologic, digital intervention reduced delusional misidentification, improved care recipient behavior, and decreased caregiver burden.

Effects of dance intervention on agitation and cognitive functioning of people living with dementia in institutional care facilities: Systematic review

INTRODUCTION

Agitation and impaired cognitive functioning are common symptoms of dementia, which require costly medication regimens that are associated with adverse effects. This study investigates the effects of dance interventions on agitation and cognitive function in people living with dementia in institutional care facilities.

METHODS

Five electronic databases were searched for eligible studies on dance interventions for people living with dementia published between 2002 and 2021. Standard deviation and post mean values were extracted. Within-group Hedges' g was computed for individual studies.

RESULTS

Six randomised controlled trials and three non-randomised studies of satisfactory quality, with a total of 610 participants, were included. Statistical analysis found significant improvements in agitation and cognitive functioning with dance interventions.

DISCUSSION

This review provided favourable evidence on the effects of dance interventions on agitation and cognitive functions in people with dementia. However, given the limited evidence, more studies are needed to confirm the effects.

Immediate Beneficial Effect of Makeup Therapy on Behavioral and Psychological Symptoms of Dementia and Facial Appearance Analyzed by Artificial Intelligence Software

BACKGROUND

Possible benefits of makeup therapy, in terms of immediate and late effects on cognitive and affective functions, have not been fully proved for dementia patients.

OBJECTIVE

To evaluate the immediate effect of makeup therapy on dementia patients.

METHODS

Female nursing home residents with dementia received either only skin care treatment (control group, n = 17) or skin care plus makeup therapy treatment (makeup therapy group, n = 19). Cognitive, affective, and activity of daily living (ADL) scores were evaluated before and just after treatments. Apparent age and emotion were also evaluated with artificial intelligence (AI) software.

RESULTS

Makeup therapy significantly improved Abe's behavioral and psychological symptoms of dementia (BPSD) score (ABS, *p < 0.05). AI software judged that makeup therapy significantly made the apparent age younger (*p < 0.05). In particular, patients with moderate ADL scores had a significantly higher happiness score in makeup therapy (*p < 0.05), with a modest correlation to the Mini-Mental State Examination (MMSE, r = 0.42, *p < 0.05). The severe baseline MMSE group reported a greater feeling of satisfaction following makeup therapy (*p < 0.05).

CONCLUSION

The present makeup therapy is a promising non-pharmacological approach to immediately alleviate BPSD in female dementia patients, and the present AI software quickly and quantitatively evaluated the beneficial effects of makeup therapy on facial appearance.

How does physical activity benefit people living with dementia? A systematic review to identify the potential mechanisms of action

Purpose

One limitation of research that assesses the effectiveness of physical activity interventions for people with dementia is that most do not describe the intervention in sufficient detail to ascertain a theoretical basis or mechanism of action that determines the effective components. This paper aims to identify studies which evaluate the mechanisms of action of physical activity interventions for people with dementia, to further inform effective intervention development.

Design/methodology/approach

Papers were screened for evidence of evaluation of specific forms of physical activity, using pre-defined inclusion criteria. Analysis was conducted to ascertain if mechanisms of action were corroborated by data within and between studies.

Findings

The authors identified 26 studies with a measured mechanism of action; these related to the effects of physical activity on either neurological structure or endocrinal markers, including hormones. Physical activity had potential to reduce hippocampal atrophy, increase neural recruitment, activate the noradrenergic system and improve anti-inflammatory responses. While individual studies were hampered by small sample sizes, the body of evidence indicated that physical activity may have potential to delay cognitive decline.

Practical implications

Mechanisms of action in relation to dementia and physical activity are likely to be multifaceted, and physical activity may be protective against progression in the early stages of cognitive decline. Physical activity may be of greatest benefit if incorporated into on-going lifestyle, rather than engaged in for short periods, and combined with social interaction.

Originality/value

This paper is unique in its focus on the mechanisms of action of physical activity interventions for people with dementia.

Focusing on Emotional and Social Intelligence Stimulation of People With Dementia by Playing a Serious Game—Proof of Concept Study

Context: Dementia is one of the top five chronic diseases, which has an overwhelming impact on patients' life quality, family, and caregivers. Currently, research relating to people with dementia (PwD) focuses on the deterioration of cognitive abilities. A more innovative approach, and the one taken by this paper, is focusing on methods to maintain and improve functionality, communication and quality of life of PwD by building on remaining capacities in the yet unexplored domain of emotional and social intelligence (ESI). The use of serious games for PwD (SG4D) aimed at building social and emotional capacity is a budding field of research.

Objectives: Proof of concept that the, low cost, easy to deploy SG4D, called “My Brain Works” (MBW), co-designed with PwD, enhances ESI, based on the Bar-On ESI model.

Methods: 27 PwD, clients at MELABEV dementia day center, participated in a mixed methods 12 weeks pilot, proof of concept study using a tablet SG4D co-designed with PwD. Quantitative performance data was collected automatically by the tablet during game sessions. In this paper we focus on the analysis of the qualitative and quantitative data related to ESI, observed by 10 different researchers, during each game session.

Results: Quantitative data revealed: both the PwD with high and low MoCA scores had similar average ESI scores. Qualitative analysis revealed that the PwD demonstrated 9 sub-components of the Bar-On ESI Model.

Conclusion: While there is no drug to stop cognitive decline associated with dementia, interventions related to ESI, on the other hand, may improve functioning and quality of life. Despite declines in cognitive abilities, our study shows that a tablet based SG4D can stimulate their ESI and evoke responses in self-awareness, empathy, social and communication capacities. Using SG4D to exercise and maintain social skills is an area that may be promising in the future and may help counter the negative effects of social isolation and loneliness. Such games, while not focusing on cognitive improvement, may also impact on cognitive functioning and help bridge the gap between caregiver and PwD. More research is needed with larger sample sizes.

Vocally disruptive behaviour in nursing home residents in Ireland: a descriptive study

BACKGROUND

Vocally disruptive behaviour (VDB) is relatively common in nursing home residents but difficult to treat. There is limited study on prevalence and treatment of VDB. We hypothesise that VDB is a result of complex interaction between patient factors and environmental contributors.

METHODS

Residents of nursing homes in south Dublin were the target population for this study. Inclusion criteria were that the residents were 65 years or over and exhibited VDB significant enough for consideration in the resident's care plan. Information on typology and frequency of VDB, Interventions employed and their efficacy, diagnoses, Cohen-Mansfield Agitation Inventory scores, Mini-Mental State Examination scores, and Barthel Index scores were obtained.

RESULTS

Eight percent of nursing home residents were reported to display VDB, most commonly screaming (in 39.4% of vocally disruptive residents). VDB was associated with physical agitation and dementia; together, these two factors accounted for almost two-thirds of the variation in VDB between residents. One-to-one attention, engaging in conversation, redirecting behaviour, and use of psychotropic medication were reported by nurses as the most useful interventions. Analgesics were the medications most commonly used (65.7%) followed by quetiapine (62.9%), and these were reportedly effective in 82.6% and 77.2% of residents respectively.

CONCLUSIONS

VDB is common, challenging, and difficult to manage. The study of VDB is limited by a variety of factors that both contribute to this behaviour and make its treatment challenging. Issues relating to capacity and ethics make it difficult to conduct randomised controlled trials of treatments for VDB in the population affected.

Art Training in Dementia: A Randomized Controlled Trial

Objectives

The present study explores the effect of visual art training on people with dementia, utilizing a randomized control trial design, in order to investigate the effects of an 8-week visual art training program on cognition. In particular, the study examines overall cognition, delayed recall, and working memory, which show deficits in people with dementia.

Method

Fifty-three individuals with dementia were randomly assigned into either an art training (n = 27) or usual-activity waitlist control group (n = 26). Overall cognition and delayed recall were assessed with the Montreal Cognitive Assessment (MoCA), and working memory was assessed with the Backward Digit Span task.

Results

There were no group differences in overall cognition, or working memory, while a difference in delayed recall was undetermined, based on post-test—pre-test difference scores. Groups were comparable at baseline on all measures.

Conclusion

The measures of cognition, delayed recall, and working memory used in this study were not affected by an 8-week visual art training program.

The Association Between a Previous Diagnosis of Mild Cognitive Impairment as a Proxy for an Early Diagnosis of Dementia and Mortality: A Study of Secondary Care Electronic Health Records

BACKGROUND

Dementia policy states that the early diagnosis of dementia can keep people living well for longer; however, there is little robust evidence to support this. Mild cognitive impairment (MCI) is considered a prodrome to dementia and can aid with the earlier diagnosis of dementia.

OBJECTIVE

The objective of this study was to use a previous diagnosis of MCI, before dementia, as a proxy for early diagnosis to investigate the relationship between an early diagnosis and mortality.

METHODS

A retrospective cohort study of electronic health care records from South London and Maudsley NHS. Patients aged 50+, diagnosed with dementia between January 2008 and November 2018, were divided into two groups: those with a previous diagnosis of MCI (early diagnosis) and those without. Cox regression models used to compare the risk of mortality between groups.

RESULTS

Of 18,557 participants, 5.6%(n = 1,030) had an early diagnosis; they had fewer cognitive, psychiatric, and functional problems at dementia diagnosis. The early diagnosis group had a reduced hazard of mortality (HR = 0.86, CI = 0.77-0.97). However, the magnitude of this effect depended on the scale used to adjust for cognitive difficulties.

CONCLUSION

A previous diagnosis of MCI is a helpful proxy for early diagnosis. There is some evidence that an early diagnosis is associated with a reduced risk of mortality; however, it is not clear how Mini-Mental State Exam scores affect this relationship. While these findings are promising, we cannot be conclusive on the relationship between an early diagnosis and mortality.

Developing an ontology for representing the domain knowledge specific to non-pharmacological treatment for agitation in dementia

INTRODUCTION

A large volume of clinical care data has been generated for managing agitation in dementia. However, the valuable information in these data has not been used effectively to generate insights for improving the quality of care. Application of artificial intelligence technologies offers us enormous opportunities to reuse these data. For health data science to achieve this, this study focuses on using ontology to coding clinical knowledge for non-pharmacological treatment of agitation in a machine-readable format.

METHODS

The resultant ontology-Dementia-Related Agitation Non-Pharmacological Treatment Ontology (DRANPTO)-was developed using a method adopted from the NeOn methodology.

RESULTS

DRANPTO consisted of 569 concepts and 48 object properties. It meets the standards for biomedical ontology.

DISCUSSION

DRANPTO is the first comprehensive semantic representation of non-pharmacological management for agitation in dementia in the long-term care setting. As a knowledge base, it will play a vital role to facilitate the development of intelligent systems for managing agitation in dementia.

How Is Quality of Life Assessed in People With Dementia? A Systematic Literature Review and a Primer for Speech-Language Pathologists

Purpose The purpose of this study was to determine how quality of life (QoL) is measured in people with dementia involved in interventions designed to improve well-being and to explore how those measures align with principles of person-centered care. Method A systematic literature review was conducted utilizing PsychInfo, CINAHL, and PubMed and combinations of the search terms: "dementia," "outcome measure," "creative engagement," "creative intervention," "TimeSlips," "art," "quality of life," and "well-being." The search was limited to studies published in peer-reviewed journals that reported outcomes for people with dementia in response to a creative intervention. Results Across the 24 reviewed studies, 30 different outcome measures were reported including eight self-reported, nine observational, and 13 proxy-reported measures. Self-report of QoL was elicited 16 times, observational measures were reported 17 times, and proxy-reported measures were used 28 times. All measures were used with participants across the dementia severity spectrum. Conclusion Current clinical practice of QoL evaluation does not align well with person-centered care principles of self-determination based on the low proportion of self-report. The previously reported limitations of proxy-report have been in part confirmed with this study. Implications of the findings for speech-language pathologists are discussed.

Green spaces, dementia and a meaningful life in the community: A mixed studies review

Engagement in green spaces impacts positively on wellbeing and quality of life. However, little is known about the impacts of green space engagement specifically for people living with the experience of dementia in the community; people with a heightened need to maintain a quality life. In this mixed study review, we explore existing evidence for quality of life impacts of contact with green spaces by people living with dementia in the community. Findings show that gardens and horticultural programs, green care farms, parks, urban woodlands and neighbourhood outdoor environments can impact positively in several ways. Four key mechanisms are identified: Engaging in meaningful activities; Empowerment; Positive risk taking; and Reinforcing Identity. These findings provide conceptual links between psychosocial understandings of the relationships between nature and wellbeing with rights-based dementia discourses. We conclude that evidence specific for people living with dementia in the community setting is growing and there is potential for green spaces to enable an active and meaningful community-life, despite cognitive decline. This is worthy of consideration by policy makers, practitioners and carers. Future studies can broaden this field of research and include investigations into lesser-explored aspects of quality of life, such as spirituality, and methods that incorporate the voices of people living with dementia.

Policy to Reduce Antipsychotic Use and Hospitalization of Nursing Home Residents With Dementia

OBJECTIVES

Following the 2012 launch of the National Partnership to Improve Dementia Care in Nursing Homes (the National Partnership), the use of antipsychotics has declined. However, little is known about the impact of this effort on quality of care and outcomes for nursing home (NH) residents with Alzheimer's disease and related dementia (ADRD). The objective of this study is to examine changes in hospitalizations for NH long-stay residents with ADRD after the launch of the National Partnership.

DESIGN

Observational cross-sectional study.

SETTING/PARTICIPANTS

NH residents who were newly admitted into NHs and became long-stay residents between January 2011 and March 2015 (n = 565,885).

METHODS

We estimated linear probability models to explore the relationship between the National Partnership and the likelihood of NH-originated hospitalizations for NH long-stay residents with ADRD, accounting for facility fixed effect, individual covariates, and concurrent changes in hospitalizations among residents without ADRD. We further stratified the analysis by NHs according to their prevalence of antipsychotic use at baseline (ie, prior to the National Partnership).

RESULTS

We detected a 0.7-percentage point relative increase (P value <.01) in risk-adjusted probabilities of hospitalizations among residents with ADRD compared with non-ADRD residents in the post-Partnership period. In the stratified analysis, we detected a 1.2-percentage point increase (P = .037) in the probability of hospitalizations among ADRD residents in NHs with high antipsychotic use at baseline but no significant change among those in NHs with low antipsychotic use.

CONCLUSIONS AND IMPLICATIONS

Although the National Partnership may have reduced exposure to antipsychotics, our findings suggest this was related to an increase in hospitalization risk for residents with ADRD. Further research is needed to elucidate the reasons behind the observed relationship and to examine the impact of the National Partnership on other health outcomes.

Non-pharmacological treatment changes brain activity in patients with dementia

Non-pharmacological treatment (NPT) improves cognitive functions and behavioural disturbances in patients with dementia, but the underlying neural mechanisms are unclear. In this observational study, 21 patients with dementia received NPTs for several months. Patients were scanned using magnetoencephalography twice during the NPT period to evaluate NPT effects on resting-state brain activity. Additionally, cognitive functions and behavioural disturbances were measured using the Mini-Mental State Examination (MMSE-J) and a short version of the Dementia Behaviour Disturbance Scale (DBD-13) at the beginning and the end of the NPT period. In contrast to the average DBD-13 score, the average MMSE-J score improved after the NPT period. Magnetoencephalography data revealed a reduced alpha activity in the right temporal lobe and fusiform gyrus, as well as an increased low-gamma activity in the right angular gyrus. DBD-13 score changes were correlated with beta activity in the sensorimotor area. These findings corroborate previous studies confirming NPT effects on brain activity in healthy participants and people at risk of dementia. Our results provide additional evidence that brains of patients with dementia have the capacity for plasticity, which may be responsible for the observed NPT effects. In dementia, NPT might lead to improvements in the quality of life.

Outcomes tested in non-pharmacological interventions in mild cognitive impairment and mild dementia: a scoping review

OBJECTIVES

Non-pharmacological treatments are an important aspect of dementia care. A wide range of interventions have been trialled for mild dementia and mild cognitive impairment (MCI). However, the variety of outcome measures used in these trials makes it difficult to make meaningful comparisons. The objective of this study is to map trends in which outcome measures are used in trials of non-pharmacological treatments in MCI and mild dementia.

DESIGN

Scoping review.

DATA SOURCES

EMBASE, PsychINFO, Medline and the Cochrane Register of Controlled Trials were searched from inception until February 2018. An additional search was conducted in April 2019 ELIGIBILITY: We included randomised controlled trials (RCTs) testing non-pharmacological interventions for people diagnosed with MCI or mild dementia. Studies were restricted to full RCTs; observational, feasibility and pilot studies were not included.

CHARTING METHODS

All outcome measures used by included studies were extracted and grouped thematically. Trends in the types of outcome measures used were explored by type of intervention, country and year of publication.

RESULTS

91 studies were included in this review. We extracted 358 individual outcome measures, of which 78 (22%) were used more than once. Cognitive measures were the most frequently used, with the Mini-Mental State Examination being the most popular.

CONCLUSIONS

Our findings highlight an inconsistency in the use of outcome measures. Cognition has been prioritised over other domains, despite previous research highlighting the importance of quality of life and caregiver measures. To ensure a robust evidence base, more research is needed to highlight which outcome measures should be used over others.

A cluster-randomized crossover trial of Montessori activities delivered by family carers to nursing home residents with behavioral and psychological symptoms of dementia

OBJECTIVES

One-on-one structured Montessori-based activities conducted with people with dementia can improve agitation and enhance engagement. These activities may however not always be implemented by nursing home staff. Family members may present an untapped resource for enabling these activities. This study aimed to evaluate the impact of the Montessori activities implemented by family members on visitation experiences with people who have dementia.

DESIGN

Cluster-randomized crossover design.

SETTING

General and psychogeriatric nursing homes in the state of Victoria, Australia.

PARTICIPANTS

Forty participants (20 residents and 20 carers) were recruited.

INTERVENTION

During visits, family members interacted with their relative either through engaging in Montessori-based activities or reading a newspaper (the control condition) for four 30-minute sessions over 2 weeks.

MEASUREMENTS

Residents' predominant affect and engagement were rated for each 30-second interval using the Philadelphia Geriatric Center Affect Rating Scale and the Menorah Park Engagement Scale. The Pearlin Mastery Scale was used to rate carers satisfaction with visits. The 15-item Mutuality Scale measured the carers quality of their relationship with the resident. Carers' mood and overall quality of life were measured using the Center for Epidemiological Studies Depression Scale and Carer-QoL questionnaires, respectively.

RESULTS

Linear regressions within the generalized estimating equations approach assessed residents' and carers' outcomes. Relative to the control condition, the Montessori condition resulted in more positive engagement (b = 13.0, 95%CI 6.3-19.7, p < 0.001) and affect (b = 0.4, 95%CI 0.2-0.6, p < 0.001) for the residents and higher satisfaction with visits for carers (b = 1.7, 95%CI 0.45-3.00, p = 0.008). No correction was applied to p-values for multiple comparisons.

CONCLUSION

This study strengthens the evidence base for the use of the Montessori programs in increasing well-being in nursing home residents. The findings also provide evidence that family members are an additional valuable resource in implementing structured activities such as the Montessori program with residents.

Namaste care in the home setting: developing initial realist explanatory theories and uncovering unintended outcomes

INTRODUCTION

The End-of-Life Namaste Care Program for People with Dementia, challenges the misconception that people with dementia are a 'shell'; it provides a holistic approach using the five senses, which can provide positive ways of communicating and emotional responses. It is proposed Namaste Care can improve communication and the relationships families and friends have with the person with dementia. Previously used in care homes, this study is the first to explore the pioneering use of Namaste Care in people's own homes.

OBJECTIVE

To develop initial programme theories detailing if, how and under which circumstances Namaste Care works when implemented at home.

DESIGN

A qualitative realist approach following the RAMESES II guidelines was employed to understand not only whether Namaste Care has positive outcomes, but also how these are generated, for whom they happen and in which circumstances.

SETTING

A hospice in the North East of England, operating in the community, through volunteers.

PARTICIPANTS

Programme theories were developed from three focus groups with volunteers implementing Namaste Care (n=8; n=8; n=11) and eight interviews with family carers (n=8).

RESULTS

Four refined explanatory theories are presented: increasing engagement, respite for family carers, importance of matched volunteers and increasing social interaction. It was identified that while Namaste Care achieved some of the same goals in the home setting as it does in the care home setting, it could also function in a different way that promoted socialisation.

CONCLUSIONS

Namaste Care provides holistic and personalised care to people with both moderate and advanced dementia, improving engagement and reducing social isolation. In the present study carers often chose to use Namaste Care sessions as respite. This was often linked to their frustration of the unavoidable dominance of task-focussed care in daily life. Individualised Namaste Care activities thus led to positive outcomes for both those with dementia and their carers.

Treatment Indications in Clinical Practice and Applied Research on Psychosocial Interventions for People With Dementia

A recent review of Cochrane meta-analyses on psychosocial interventions (PIs) concludes that clinical trials fail to confirm PIs effective for all types of dementia at every stage of the disease. This article describes how and to what extent it is necessary to identify treatment indications when researching PIs and employing them in clinical practice. Twelve Cochrane reviews on PIs for people with dementia, selected because of their systematic methodology, were searched to identify outcomes related to treatment indications (dosage, type of dementia, severity…). The authors identified several research and practice issues that related to treatment indications: sample profiling, hypothesizing and statistical interpretation, external validity, effectiveness of interventions, contraindications and limits of interventions, and tailoring. Developing an effective PI requires empirical, developmental, exploratory, and confirmatory development stages to achieve credibility and robustness.

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.

Musical Features and Affective Responses to Personalized Playlists in People With Probable Dementia

OBJECTIVES

Personalized music playlists are increasingly being utilized in aged care settings. This study aims to investigate how musical features influence the affective response to music of people with probable dementia.

METHODS

A factorial experiment (2 × 2 × 3) was conducted to investigate the influence of tempo (fast, slow), mode (major, minor), and lyrics (none, negative, positive). Ninety-nine people with probable dementia were randomly assigned to 3 conditions, listening to 3 personalized playlists. Galvanic skin response and activation of facial action units were measured.

RESULTS

Music with fast tempos increased arousal and reduced enjoyment. Music in minor keys increased activation of the depressor anguli oris, suggesting increased sadness. Lyrics had no significant effect on response.

DISCUSSION

The findings demonstrate that both tempo and mode influenced the response of the listener. As well as accounting for personal preferences, music for people with dementia should be carefully targeted toward the affective outcome desired.

Interventions for hearing and vision impairment to improve outcomes for people with dementia: a scoping review

ABSTRACTBackground:Age-related hearing and vision problems are common among people with dementia and are associated with poorer function, reduced quality of life and increased caregiver burden. Addressing sensory impairments may offer an opportunity to improve various aspects of life for people with dementia.

METHODS

Electronic databases were searched using key terms dementia, hearing impairment, vision impairment, intervention, and management. Database searches were supplemented by hand searching bibliographies of papers and via consultation with a network of health professional experts. Studies were eligible for inclusion if they included adults aged over 50 with dementia with adult-onset hearing or vision impairment who had received a hearing or vision intervention in relation to cognitive function, rate of decline, psychiatric symptoms, hearing/vision-related disability, quality of life, and/or caregiver burden outcomes. A range of study designs were included. Results were summarized descriptively according to level of evidence and effect sizes calculated where possible. Risk of bias was assessed using Downs and Black's (1998) checklist. The development of the intervention was summarized according to the CReDECI2 scheme. PROSPERO review registration number 2016:CRD42016039737.

RESULTS

Twelve papers describing hearing interventions and five papers describing vision interventions were included. Most were of low to moderate quality. One high quality randomized controlled trial of a hearing aid intervention was identified. Hearing interventions included provision of hearing aids, assistive listening devices, communication strategies, hearing aid trouble shooting, and cochlear implantation. Vision interventions included prism lenses, rehabilitation training, and cataract surgery. There was no consistent evidence for the positive impact of hearing/vision interventions on cognitive function, rate of cognitive decline, quality of life, or caregiver burden.

CONCLUSION

Sensory interventions may promote better outcomes, but there is a need for properly powered, controlled trials of hearing and vision interventions on outcomes relevant to people living with dementia.

The Multidisciplinary Approach to Alzheimer's Disease and Dementia. A Narrative Review of Non-Pharmacological Treatment

Background: Alzheimer's disease (AD) and dementia are chronic diseases with progressive deterioration of cognition, function, and behavior leading to severe disability and death. The prevalence of AD and dementia is constantly increasing because of the progressive aging of the population. These conditions represent a considerable challenge to patients, their family and caregivers, and the health system, because of the considerable need for resources allocation. There is no disease modifying intervention for AD and dementia, and the symptomatic pharmacological treatments has limited efficacy and considerable side effects. Non-pharmacological treatment (NPT), which includes a wide range of approaches and techniques, may play a role in the treatment of AD and dementia. Aim: To review, with a narrative approach, current evidence on main NPTs for AD and dementia. Methods: PubMed and the Cochrane database of systematic reviews were searched for studies written in English and published from 2000 to 2018. The bibliography of the main articles was checked to detect other relevant papers. Results: The role of NPT has been largely explored in AD and dementia. The main NPT types, which were reviewed here, include exercise and motor rehabilitation, cognitive rehabilitation, NPT for behavioral and psychological symptoms of dementia, occupational therapy, psychological therapy, complementary and alternative medicine, and new technologies, including information and communication technologies, assistive technology and domotics, virtual reality, gaming, and telemedicine. We also summarized the role of NPT to address caregivers' burden. Conclusions: Although NPT is often applied in the multidisciplinary approach to AD and dementia, supporting evidence for their use is still preliminary. Some studies showed statistically significant effect of NPT on some outcomes, but their clinical significance is uncertain. Well-designed randomized controlled trials with innovative designs are needed to explore the efficacy of NPT in AD and dementia. Further studies are required to offer robust neurobiological grounds for the effect of NPT, and to examine its cost-efficacy profile in patients with dementia.
