Management of neuropsychiatric symptoms of dementia in clinical settings: recommendations from a multidisciplinary expert panel

Programa Personalizado de Atividades (TAP-BR): proposição de uma versão ambulatorial e avaliação dos seus impactos na demência - Estudo piloto

Resumo Introdução O Programa Personalizado de Atividades (TAP-BR) é um programa de intervenção em terapia ocupacional que apresenta resultados promissores na redução dos sintomas comportamentais e psicológicos da demência (SCPD). Objetivos Propor adaptações no TAP-BR para a criação de uma versão ambulatorial desse programa e avaliar o impacto e a sua aplicabilidade. Métodos O TAP-BR foi adaptado para uso e aplicação em ambulatório e foi feita a avaliação da aplicabilidade dessa versão a partir da percepção dos estagiários do último ano do curso de graduação em terapia ocupacional e dos cuidadores familiares. O Inventário Neuropsiquiátrico (INP) e a Escala de Depressão, Ansiedade e Estresse (DASS 21) foram utilizados para avaliar o impacto da versão adaptada. Resultados Foram propostas as seguintes alterações no processo de aplicação do TAP-BR em ambulatório: adequações de termos no Manual de Intervenção e na Pasta de Documentação; adequação da avaliação ambiental a ser realizada a partir de entrevista com o cuidador; redução na duração das sessões, de 90 para 60 minutos. Na visão dos estagiários e cuidadores familiares, o programa se apresentou de fácil aplicação. As medidas apontaram que houve melhora no desgaste dos cuidadores em relação aos SCPD dos idosos (Cohen d=0,49) e em seu estado emocional (Cohen d=0,59), principalmente para a variável depressão (Cohen d=0,81). Conclusão A versão ambulatorial do TAP-BR é um programa de fácil aplicação, com impacto positivo na redução dos SCPD nos idosos e melhora no estado emocional dos cuidadores, com ênfase na variável depressão.

Emotional and Neuropsychiatric Disorders Associated with Alzheimer's Disease

Alzheimer's disease is associated with impairments in emotional communication including comprehension and production of facial emotional expressions, comprehension of affective prosody, and alexithymia. It is also associated with disorders of emotional experience including mood disorders (depression and anxiety), agitation/aggression, and psychosis. Agitation/aggression and psychosis are particularly disruptive, are associated with earlier institutionalization, and pose a major challenge to institutional management. Treatment of disorders of emotional experience has been primarily pharmacologic (reviewed here in detail) and has relied heavily on antipsychotic medications despite the small effect sizes demonstrated in a large number of randomized controlled trials and the prevalence of serious side effects associated with these drugs. Recent studies suggest that treatment with pimavanserin, an antipsychotic without activity at dopamine receptors, may represent an important advance for treatment of psychotic manifestations, even as the drug appears to pose significant risk. Dextromethorphan/quinidine may represent an important advance in the treatment of agitation/aggression. There is also compelling evidence that sleep disorders, which are common among patients with Alzheimer's disease and are readily treatable, may potentiate psychotic manifestations and agitation/aggression, but further studies are needed.

Co-designing complex interventions with people living with dementia and their supporters

BACKGROUND AND OBJECTIVES

We engaged people living with dementia, family carers and health and social care professionals in co-designing two dementia care interventions: for family carers and people living with dementia (New Interventions for Independence in Dementia Study (NIDUS)-family and home-care workers (NIDUS-professional training programme).

RESEARCH DESIGN AND METHODS

Over October 2019-March 2020, we invited public and patient (PPI) and professional members of our NIDUS co-design groups to complete the PPI Engagement Evaluation Tool (designed to assess engagement activities), and non-professional PPI members to participate in qualitative telephone interviews. We thematically analysed and integrated mixed-methods findings.

RESULTS

Most (15/20; 75%) of the PPI members approached participated. We identified four themes: (1) Creating the right atmosphere: participants found group meetings positive and enabling, though one health professional was unsure how to position themselves within them; (2) Participants influencing the outcome: while most members felt that they had some influence, for one carer consultation seemed too late to influence; (3) Having the right information: several carers wanted greater clarity and more regular updates from researchers; (4) Unique challenges for people living with dementia: memory problems presented challenges in engaging with substantial information, and within a large group.

DISCUSSION AND IMPLICATIONS

We reflect on the importance of providing accessible, regular updates, managing power imbalances between co-design group members with lived and professional experiences; and ensuring needs and voices of people living with dementia are prioritised. We encourage future studies to incorporate evaluations of co-design processes into study design.

As-Needed Prescribing and Administration of Psychotropic Medications in Assisted Living: A 7-State Study

OBJECTIVES

Psychotropic medications administered on an as-needed basis, often designated as pro re nata (or PRN, hereafter as-needed), can alleviate acute symptoms and facilitate deprescribing, although as-needed use is associated with negative outcomes such as polypharmacy and drug interactions. The aim of this study was to examine the extent to which PRN psychotropic medications are prescribed and administered to assisted living (AL) residents, overall and in relation to resident- and community-level characteristics.

DESIGN

Cross-sectional study.

SETTING AND PARTICIPANTS

All AL residents and select staff in 250 AL communities in 7 states.

METHODS

Data regarding prescribing and administration of 5 types of PRN psychotropic medications in the prior 7 days (antipsychotics, mood stabilizers and antiepileptics, antidepressants, anxiolytics/hypnotics, and cognitive enhancers) were abstracted and compared across resident and community characteristics.

RESULTS

Prescribing of PRN psychotropics in AL is low (10.3%). Of prescribed PRN medications, 2.5% of residents were administered a PRN and 8% had PRN that was not administered in the previous 7 days. Anxiolytics were administered PRN more commonly compared with antipsychotics (2.0% vs 0.2%). Of all PRN psychotropic prescriptions (n = 1039), 70.5% had a written indication describing the reason for administration. Among PRN medications administered (n = 242), the proportion with an indication was lower (62.0%). PRN psychotropic medication prescribing was higher among residents with dementia and a psychiatric diagnosis, and in larger AL communities and those with a higher proportion of dementia care beds.

CONCLUSIONS AND IMPLICATIONS

The prescribing and administration of PRN psychotropic medications in AL is relatively rare, although more common among residents with dementia. Emerging psychotropic medication policies should be expanded to address mental health care, anxiolytic/hypnotic use for residents living with dementia, PRN prescribing in chart review, and the use of detailed indications for PRN use, especially when medications are administered by unlicensed care staff.

Blood-based biomarkers of agitation in Alzheimer's disease: Advances and future prospects

Agitation is a common neuropsychiatric symptom that becomes more prevalent as Alzheimer's disease (AD) increases in severity. The treatment of agitation is an urgent and unmet need due to the poor outcomes associated with it, its disruptive impact on patients and caregivers, and the lack of efficacious and safe treatments. Recent research on agitation in AD with blood-based biomarkers has advanced the search for its biomarkers beyond the brain and provides new insights to understand its mechanisms and improve treatments. Here, we reviewed studies of blood-based biomarkers of agitation in AD, which show that inflammatory biomarkers are increased in patients with agitation, may predict the development of agitation, and are associated with symptom severity. In addition, they may also track symptom severity and response to treatment. Other biomarkers associated with agitation include markers of oxidative stress, brain cholesterol metabolism, motor activity, and clusterin, a chaperone protein. These results are promising and need to be replicated. Preliminary evidence suggests a role for these biomarkers in interventional studies for agitation to predict and monitor treatment response, which may eventually help enrich study samples and deliver therapy likely to benefit individual patients. Advances in blood-based biomarkers of AD including those identified in "-omic" studies and high sensitivity assays provide opportunities to identify new biomarkers of agitation. Future studies of agitation and its treatment should investigate blood-based biomarkers to yield novel insights into the neurobiological mechanisms of agitation, monitoring symptoms and response to treatment, and to identify patients likely to respond to treatments.

You can tell it works - Experiences from using the VIPS practice model in primary healthcare

INTRODUCTION

Person-centred care is a philosophy rather than a method ready for implementation and utilization in daily clinical work. Internationally, few methods for person-centred care have been widely adopted in clinical dementia care practice. In Norway, the VIPS practice model is one that is commonly used for the implementation and use of person-centred care in primary healthcare.

METHOD

Nursing home physicians, managers and leaders in the municipalities, care institutions and domestic nursing care services were eligible for inclusion if their workplace had implemented and used the VIPS practice model for a minimum of 12 months. Individual interviews were conducted via Facetime, Skype or telephone and analysed with qualitative content analysis.

FINDINGS

In all, 20 respondents were included: one manager of health and care services in the municipality, six managers and leaders working in domestic care or daytime activity centres and 10 managers/leaders and three physicians working in nursing homes. Two global categories emerged: category 1: Change in staff's professional reasoning with two sub-categories: (a) an enhanced professional level in discussions and (b) a change in focus from task to person; and category 2: Changes in the clinical work, with three sub-categories: (a) effective interventions, (b) a person-centred work environment and (c) changes in cooperation between stakeholders.

CONCLUSION

Regular use of the VIPS practice model appeared to change the work culture for the benefit of both service users and frontline staff. Increased cooperation between frontline staff, nurses, physicians and next of kin was described. Staff were more focused on the needs of the service users, which resulted in care interventions tailored to the needs of the individual with dementia, loyalty to care plans and fewer complaints from next of kin.

Physical exercise as a non-pharmacological strategy for reducing behavioral and psychological symptoms in elderly with mild cognitive impairment and dementia: a systematic review of randomized clinical trials

BACKGROUND

Elderly people with dementia may exhibit behavioral and psychological symptoms throughout the course of disease. Non-pharmacological therapies, such as regular physical activity, are considered strategies for managing these symptoms.

OBJECTIVE

The aim of this study was to investigate whether participation in physical exercise programs is effective in reducing behavioral and neuropsychiatric symptoms in elderly people with Mild Cognitive Impairment (MCI) and dementia.

METHODS

A literature review was carried out in MEDLINE (PubMed), SciELO, Web of Science, Scopus and SPORTDiscus databases from 2010 to 2020. The eligible studies were randomized clinical trials involving elderly people with mild cognitive impairment or dementia and assessing changes in neuropsychiatric and psychological symptoms as primary or secondary outcomes. The studies had a group with only physical exercise as an intervention compared to a control group.

RESULTS

Of 175 publications identified in the initial survey, only 7 studies met the eligibility criteria. Four out of 7 studies demonstrated positive effects in reducing behavioral symptoms, while the others did not report differences between gains according to the type of protocol.

CONCLUSIONS

Moderate to intense aerobic and muscle strengthening exercises may have a potential benefit in the management of behavioral and psychological symptoms in dementia, but studies varied in their conclusions. This review indicates the need for further intervention studies to investigate, as a primary outcome, the absolute effect of physical exercise and its impact on behavioral and psychological symptoms in elderly people with MCI dementia, especially in the early stages of the disease.

Impact of an interdisciplinary intervention for distress behaviors in dementia on psychotropic drug use in Veterans Health Administration Community Living Centers: STAR-VA impact on psychotropic drug utilization

STAR-VA is an interdisciplinary behavioral approach for managing distress behaviors in residents with dementia, implemented at Veterans Health Administration nursing homes. This study evaluated the impact of STAR-VA implementation on psychotropic drug use. The study design is a retrospective, quasi-experimental cohort analysis of residents enrolled as STAR-VA training cases compared with eligible residents at untrained sites to evaluate treatment effects on psychotropic medication use. We matched 229 STAR-VA cases with 1,163 comparisons. STAR-VA cases experienced an average reduction of 0.92 "as-needed" doses per month (95% confidence interval [CI] -1.82, -0.02) compared with controls. No significant effect on non-STAR-VA cases in trained facilities was detected. STAR-VA programs are an important option for reducing potentially inappropriate psychotropic use.

A Systematic Review of Mindfulness-Based Interventions for Patients with Mild Cognitive Impairment or Dementia and Caregivers

The aim of this article was to systematically review the quality and efficacy of the current evidence for mindfulness-based interventions (MBIs) in patients with mild cognitive impairment (MCI), patients with dementia (PwD), and their caregivers. We identified 20 randomized controlled trials (RCTs) (11 for patients, 9 for caregivers) published in the last 15 years. Evidence suggested that MBIs are highly acceptable and credible treatments for patients with MCI, PwD and caregivers. Specifically, for PwD, the results indicated that the magnitude of post-treatment effects of MBIs are in the medium to large range for psychosocial outcomes, and in the small to medium range for cognitive functioning; however, treatment effects on dementia biomarkers were mixed, ranging from small to large, depending on the outcome measure. Findings also evidenced salutary effects of MBIs for caregivers of PwD, with post-treatment effects ranging from medium to large for caregiver stress and burden and large effects for quality of life, and mixed outcomes for cognitive functioning, with effects in the small to large range. However, confidence in these findings is relatively limited due to methodological limitations, especially in terms of poor consistency in intervention strategies, outcome measures, and other key criteria across studies. To better assess the value of MBIs for these populations and optimize treatment outcomes, we recommend further research with improved study methodology (e.g., multi-method assessment, universal criterion and outcome measures, use of active control groups, larger sample sizes, long-term follow-up) to replicate current findings and enhance our understanding of underlying treatment mechanisms of MBIs.

Factors Associated With Behavioral and Psychological Symptoms of Dementia: Prospective Observational Study Using Actigraphy

BACKGROUND

Although disclosing the predictors of different behavioral and psychological symptoms of dementia (BPSD) is the first step in developing person-centered interventions, current understanding is limited, as it considers BPSD as a homogenous construct. This fails to account for their heterogeneity and hinders development of interventions that address the underlying causes of the target BPSD subsyndromes. Moreover, understanding the influence of proximal factors-circadian rhythm-related factors (ie, sleep and activity levels) and physical and psychosocial unmet needs states-on BPSD subsyndromes is limited, due to the challenges of obtaining objective and/or continuous time-varying measures.

OBJECTIVE

The aim of this study was to explore factors associated with BPSD subsyndromes among community-dwelling older adults with dementia, considering sets of background and proximal factors (ie, actigraphy-measured sleep and physical activity levels and diary-based caregiver-perceived symptom triggers), guided by the need-driven dementia-compromised behavior model.

METHODS

A prospective observational study design was employed. Study participants included 145 older adults with dementia living at home. The mean age at baseline was 81.2 (SD 6.01) years and the sample consisted of 86 (59.3%) women. BPSD were measured with a BPSD diary kept by caregivers and were categorized into seven subsyndromes. Independent variables consisted of background characteristics and proximal factors (ie, sleep and physical activity levels measured using actigraphy and caregiver-reported contributing factors assessed using a BPSD diary). Generalized linear mixed models (GLMMs) were used to examine the factors that predicted the occurrence of BPSD subsyndromes. We compared the models based on the Akaike information criterion, the Bayesian information criterion, and likelihood ratio testing.

RESULTS

Compared to the GLMMs with only background factors, the addition of actigraphy and diary-based data improved model fit for every BPSD subsyndrome. The number of hours of nighttime sleep was a predictor of the next day's sleep and nighttime behaviors (odds ratio [OR] 0.9, 95% CI 0.8-1.0; P=.005), and the amount of energy expenditure was a predictor for euphoria or elation (OR 0.02, 95% CI 0.0-0.5; P=.02). All subsyndromes, except for euphoria or elation, were significantly associated with hunger or thirst and urination or bowel movements, and all BPSD subsyndromes showed an association with environmental change. Age, marital status, premorbid personality, and taking sedatives were predictors of specific BPSD subsyndromes.

CONCLUSIONS

BPSD are clinically heterogeneous, and their occurrence can be predicted by different contributing factors. Our results for various BPSD suggest a critical window for timely intervention and care planning. Findings from this study will help devise symptom-targeted and individualized interventions to prevent and manage BPSD and facilitate personalized dementia care.

Behaviour assessment tools in long-term care homes in Canada: a survey

OBJECTIVE

Many people living in long-term care homes (LTCH) experience changes in behaviour termed the behavioural and psychological symptoms of dementia (BPSD). The valid and reliable assessment of BPSD is essential to guide treatment and monitor the effect of interventions. The aim of this study was to identify behavioural assessment tools implemented in LTCH and factors that impact on their use in clinical care.

METHODS

We completed an online mixed-design survey of 300 randomly selected Canadian LTCH between September and November 2018. Respondents were asked to report tools used, reasons for use, methods of administration, training/supports available, confidence in use and challenges faced. Survey results were summarized descriptively and the correlation between implementation supports and confidence examined. Free-text responses were analysed qualitatively.

RESULTS

Of 300 LTCH invited to participate, 103 completed the survey. Homes reported using a mean 2.2 ± 1.1 (range 0-7) different tools. The two most commonly used tools were the Dementia Observation System (DOS) and Cohen-Mansfield Agitation Inventory (CMAI). Overall confidence in most aspects of tool use was reported to be high, with workload identified as the greatest challenge. Training and supports correlated with confidence in tool use. Qualitative findings indicate tools provide valuable data to understand behaviours, facilitate team communication, target interventions and track outcomes.

CONCLUSIONS

Behavioural assessment tools, in particular a direct observation tool, are widely used in clinical care in Canadian LTCH. Education, enhanced resources, leadership support and applications of technology represent opportunities to improve their use.

The Prevalence of and Documented Indications for Antipsychotic Prescribing in Irish Nursing Homes

Background: Antipsychotic medications are often used ‘off-licence’ to treat neuropsychiatric symptoms and disorders of aging and to manage behavioural and psychological symptoms of dementia despite the warnings of adverse effects. Objective: To establish the prevalence of and documented indication for antipsychotic medication use in the Irish nursing home setting. Setting: This study was conducted in six nursing homes located in Co. Cork, Ireland. Method: A retrospective, cross-sectional study was employed. All patients who met the inclusion criteria (≥65 years, residing in a nursing home on a long-term basis) were eligible for inclusion. There were 120 nursing home residents recruited to the study. Main Outcome Measure: The prevalence of antipsychotic medication use in nursing home residents (with and without dementia). Results: The overall prevalence of antipsychotic prescribing was found to be 48% and patients with dementia were significantly more likely to be prescribed an antipsychotic compared to those without dementia (67% vs. 25%) (χ² (1, N = 120) = 21.541, p < 0.001). In the cohort of patients with dementia, there was a trend approaching significance (p = 0.052) of decreasing antipsychotic use with increasing age (age 65–74 = 90%; age 75–84 = 71%; age 85 and over = 58%). An indication was documented for 84% of the antipsychotic prescriptions in this cohort. Conclusions: The findings of this study highlight that high rates of antipsychotic medication use remains an issue in Irish nursing homes. Further work should explore factors in influencing prescribing of these medications in such settings.

Driving and Alzheimer's dementia or mild cognitive impairment: a systematic review of the existing guidelines emphasizing on the neurologist's role

BACKGROUND

Driving is a complex task requiring the integrity and the cooperation of cognition, motor, and somatosensory skills, all of which are impacted by neurological diseases.

OBJECTIVE

Identification of neurologist's role when assessing fitness to drive of cognitively impaired individuals.

METHODS

We performed a systematic review of the guidelines/recommendations (G/Rs) regarding the evaluation of driving fitness of patients with mild cognitive impairment (MCI) and/or dementia. Emphasis was put on the neurological and neuropsychological aspects of the evaluation.

RESULTS

Eighteen G/Rs were included in the review (9 national guidelines, 5 recommendation papers, 3 consensus statements, and 1 position paper). All G/Rs referred to drivers with dementia and 9/18 referred to drivers with MCI. A common approach among G/Rs is the initial trichotomization of patients in safe to drive, unsafe to drive, and undetermined cases, which are referred to a second-line evaluator. First-line evaluators are general practitioners in 10/18 G/Rs; second-line evaluators are neurologists in 7/18 G/Rs. Specific neuropsychological tests are proposed in 11/18 G/Rs and relative cut-off values in 7/18. The most commonly used tests are the MMSE, TMT, and CDT. A thorough neurological examination is proposed in only 1/18 G/R.

CONCLUSION

Although extensive multi-disciplinary research has provided useful information for driving behavior of cognitively impaired individuals, we are still far from a widely accepted approach of driving ability evaluation in this increasing population. A comprehensive assessment from a multi-disciplinary team in which the neurologist plays a critical role seems to be required, although this has not yet been implemented in any G/Rs.

Evaluation and Effectiveness of Dementia Staff Training Programs in General Hospital Settings: A Narrative Synthesis with Holton's Three-Level Model Applied

Background:

People with Dementia (PwD) are frequently admitted to hospital settings. The lack of proper dementia knowledge, poor communication skills, negative attitudes toward dementia, and lack of confidence affects the quality of care, thus development of dementia trainings has increased. Nevertheless, literature regarding the effectiveness of training implementation is limited.

Objective:

The aim of this narrative synthesis is to 1) identify the characteristics of training programs and 2) explore the effectiveness of these training programs in everyday clinical practice.

Methods:

A systematic search in PubMed, PsycINFO, CINAHL, and Cochrane was conducted, including qualitative and quantitative peer-reviewed studies. Holton’s evaluation model with its three outcome levels (learning, individual performance, and organizational results) was adopted. 14 studies were included.

Results:

The synthesis of the results was divided into two parts: 1) to describe the characteristics and content of trainings 2) to evaluate the effectiveness of training programs according to the three outcome levels of Holton’s model, taking into consideration its construct domains: ability, motivation, and environment. Learning outcomes were assessed in all selected studies: 13 studies observed changes in individual performance, four studies reported changes within the organizational level, and only five showed sustainable changes over time.

Conclusion:

Person-centered care (PCC) approaches, interactive and varied teaching methods, supporting conditions like champions, action plans, and setting care policies, are all characteristics of effective trainings. Successful programs should be sustainable over time, demonstrating positive outcomes across the organization. Based on current findings, there is a lack of adequate evaluation with regard to training programs on the organizational level.

Process evaluation of an implementation study in dementia care (EIT-4-BPSD): stakeholder perspectives

BACKGROUND

Behavioral and psychological symptoms of distress in dementia (BPSD) are major drivers of poor quality of life, caregiver burden, institutionalization, and cost of care in nursing homes. The Evidence Integration Triangle (EIT)-4-BPSD in nursing homes was a pragmatic Hybrid III trial of an implementation strategy to help staff use evidence-based non-pharmacological interventions to prevent and manage BPSD. This study aimed to describe and explore the stakeholders' perceptions of the process to implement the EIT-4-BPSD strategy including its utility, and the barriers and facilitators to implementation in real-world settings.

METHODS

EIT-4-BPSD was a multi-layer implementation strategy that engaged nursing home stakeholder groups to define community specific goals towards reducing BPSD over a 12-month period. Stakeholder groups from nursing homes that completed all 12-months of the implementation strategy were invited to participate in this process evaluation study. Qualitative data from focus group transcripts were analyzed using a conventional content analysis. Emerging codes were sorted into categories, then organized in meaningful clusters based on the domains of the RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) framework.

RESULTS

The EIT-4-BPSD implementation strategy was completed in 21 nursing homes; 93 stakeholders participated in focus groups. Over half of participating nursing homes reported meeting their BPSD goals as expected or more. Challenges, facilitators, and contextual factors reported by stakeholder members explains variability in the implementation of EIT-4-BPSD strategy in 11 key categories: family; staff; organizational; staff, environmental, and resident outcomes; utility of EIT resources; adoption barriers and facilitators; care process adaptations; and future planning.

CONCLUSION

Stakeholders offered guidance on salient factors influencing the feasibility and utility of EIT-4-BPSD adoption and implementation to consider in future implementation research that aims to improve behavioral well-being in NH residents living with dementia. Engagement of family and staff at all levels of the organization (Management, leadership, and direct care); and measurement of staff, environmental, and resident outcomes were perceived as critical for future implementation success. While regulations, finances, and competing demands on staff time were perceived as reducing implementation success.

TRIAL REGISTRATION

The Testing the Implementation of EIT-4-BPSD study was registered in the ClinicalTrials.gov ( NCT03014570 ) January 9, 2017.

Medications causing potential cognitive impairment are common in nursing home dementia units – A cross-sectional study

Background

With advancing age the brain becomes more sensitive to centrally acting drugs thus increasing the risk of cognitive side-effects. The Swedish National Board of Health and Welfare developed indicators to measure and follow quality in older people's drug therapy, one being “Potentially Inappropriate Medications risking Cognitive impairment (PIMcogn)”. Associations between anticholinergics and cognitive impairment are described, especially in persons with Alzheimer's disease or Lewy Body Dementia/Parkinson's disease dementia, due to degenerated cholinergic pathways.

Objectives

To examine the prevalence of PIMcogn and if it differed between nursing home residents with and without a dementia diagnosis and between residents with different dementia aetiologias.

Methods

Descriptive cross-sectional study, based on residents ≥65 years in nursing home dementia units in Malmö, Sweden, in 2012–2013 (N = 574).

Results

The study population consisted of 76% women, the mean age was 86 years and a dementia diagnosis was registered in 92%. A total of 74% were prescribed at least one PIMcogn. Benzodiazepines were prevalent in 59%, opioids in 27%, antipsychotics in 20% and anticholinergics in 13%. Opioids used regularly and antiepileptics were more common in residents without a dementia diagnosis. The lowest proportion of anticholinergics was seen in the oldest age group, 11.0%. There was no difference seen in anticholinergics between dementia types with considerable cholinergic deficit and other dementia diagnoses.

Conclusions

Treatment with at least one PIMcogn was common. Usage of benzodiazepines and antipsychotics was, despite the knowledge of alarming side-effects, high.

An awareness of the inappropriateness in prescribing anticholinergics to the oldest old seems to be apparent, but not to persons with cholinergic deficit.

•

Benzodiazepine use was alarmingly high, despite the knowledge of increased risk of sedation, cognitive impairment, delirium and fall in older people.

•

Antipsychotics were common in residents with dementia. This is worrying since alarming side-effects are seen in these persons and treatment effects of antipsychotics are modest in BPSD.

•

An awareness of the inappropriateness in prescribing anticholinergics to the oldest old seem to be apparent, but not to persons with cholinergic deficit due to Alzheimer's disease or LBD/PDD.

The effect of COVID-19 isolation measures on the cognition and mental health of people living with dementia: A rapid systematic review of one year of quantitative evidence

BACKGROUND

COVID-19 prevention and control policies have entailed lockdowns and confinement. This study aimed to summarize the global research evidence describing the effect of COVID-19 isolation measures on the health of people living with dementia.

METHODS

We searched Pubmed, PsycINFO and CINAHL up to 27th of February 2021 for peer-reviewed quantitative studies about the effects of isolation during COVID-19 on the cognitive, psychological and functional symptoms of people with dementia or mild cognitive impairment. The Joanna Briggs Institute critical appraisal tool was used to conduct the quality assessment. PROSPERO registration: CRD42021229259.

FINDINGS

15 eligible papers were identified, examining a total of 6442 people with dementia. 13/15 studies investigated people living in the community and 2 in care homes. Out of 15 studies, 9 (60%) reported changes in cognition and 14 (93%) worsening or new onset of behavioral and psychological symptoms. Six studies (46%) reported a functional decline in daily activities in a variable proportion of the population analyzed.

INTERPRETATION

COVID-19 isolation measures have damaged the cognitive and mental health of people with dementia across the world. It is urgent to issue guidance that balances infection control measures against the principles of non-maleficence to guarantee fair and appropriate care during pandemic times for this population.

Rehabilitation in Dementia

Dementia is an eurodegenerative disorder, which causes significant disability, especially among the elderly population worldwide. The affected person shows a progressive cognitive decline, which interferes with the independence in performing the activities of daily living. Other than the cognitive domain, the patient tends to have neuropsychiatric, behavioral, sensorimotor, speech, and language-related issues. It is expected that the global burden of the disease will rise with more people entering the geriatric age group. By 2050 close, to 140 million people will be living with one or the other type of dementia. Alzheimer's disease contributes to more than 60% of cases worldwide, followed by vascular dementia. Pharmacotherapy has a limited role to play in the treatment, and at present, no drug is available, which can halt or reverse the progress of the disease. World Health Organization has mandated rehabilitation as a core recommendation in the global action plan on the public health response to dementia. Rehabilitation services are widely recognized as a practical framework to maximize independence and community participation in dementia care. The rehabilitation program is customized to achieve the desired goals, as each person has different experiences, preferences, motivations, strengths, and requirements based on type, course, and severity of the illness. It is an interdisciplinary-team approach with the involvement of several health care professionals. This article reviews the existing literature and outlines the effective rehabilitation strategies concisely in dementia care.

Adjunctive Therapy to Manage Neuropsychiatric Symptoms in Moderate and Severe Dementia: Randomized Clinical Trial Using an Outpatient Version of Tailored Activity Program

BACKGROUND

Neuropsychiatric symptoms (NPS) such as aggression, apathy, agitation, and wandering may occur in up to 90%of dementia cases. International guidelines have suggested that non-pharmacological interventions are as effective as pharmacological treatments, however without the side effects and risks of medications. An occupational therapy method, called Tailored Activity Program (TAP), was developed with the objective to treat NPS in the elderly with dementia and has been shown to be effective.

OBJECTIVE

Evaluate the efficacy of the TAP method (outpatient version) in the treatment of NPS in individuals with dementia and in the burden reduction of their caregivers.

METHODS

This is a randomized, double-blind, controlled clinical trial for the treatment of NPS in dementia. Outcome measures consisted of assessing the NPS of individuals with dementia, through the Neuropsychiatric Inventory-Clinician rating scale (NPI-C), and assessing the burden on their caregivers, using the Zarit Scale. All the participants were evaluated pre-and post-intervention.

RESULTS

54 individuals with dementia and caregivers were allocated to the experimental (n = 28) and control (n = 26) groups. There was improvement of the following NPS in the experimental group: delusions, agitation, aggressiveness, depression, anxiety, euphoria, apathy, disinhibition, irritability, motor disturbance, and aberrant vocalization. No improvement was observed in hallucinations, sleep disturbances, and appetite disorders. The TAP method for outpatient settings was also clinically effective in reducing burden between caregivers of the experimental group.

CONCLUSION

The use of personalized prescribed activities, coupled with the caregiver training, may be a clinically effective approach to reduce NPS and caregiver burden of individuals with dementia.

Impact of STAR-VA on Staff Injury and Disruptive Behavior Reports in VA Nursing Homes

OBJECTIVES

Workplace disruptive behavior incidents can be costly for organizations, employees, and customers. Persons with dementia living in long-term care settings have a high risk of exhibiting distressed behaviors. We examined whether a resident-centered, behavioral intervention for residents with dementia led to a reduction in reported workplace disruptive behaviors and staff injury rate due to assault. Impactful interventions are important for quality of care.

DESIGN

We examined whether a team-based behavioral program in community living centers (CLCs), where a nurse champion and behavioral coordinator were trained to work with the clinical team to understand and manage distressed behaviors commonly associated with dementia, was associated with reductions in behavior incidents.

SETTING AND PARTICIPANTS

The setting was Veterans Health Administration CLCs. The sample consisted of 120 aggregated CLCs operating between 2012 and 2017 with 62 completing training. CLCs were distributed across the United States.

METHODS

Outcomes included CLC-level rates of staff injury and number of workplace disruptive behavior incidents. Outcomes were regressed on measures of intervention completion, time since intervention, and several CLC characteristics.

RESULTS

The intervention was significantly associated with lower incidence of assault with staff injury rates overall, particularly following the first year of training, but not with other reported workplace disruptive behavior incident rates.

CONCLUSIONS AND IMPLICATIONS

A team-based behavioral intervention was associated with reduction of employee assaults, a critical repercussion of distressed behavior in dementia. Given rapid growth in patients with dementia in nursing homes, effective treatment practices, such as interdisciplinary behavioral management approaches may be impactful and valuable to implement.

Bright Light Therapy in Older Adults with Moderate to Very Severe Dementia: Immediate Effects on Behavior, Mood, and Physiological Parameters

Bright light therapy (BLT) has demonstrated positive short- and long-term effects in people with cognitive impairment or dementia; however, the immediate impact of BLT sessions has been scarcely investigated. In this study, we aimed to explore the immediate effects of BLT on behavior, mood, and physiological parameters (oxygen saturation/heart rate) in a sample of institutionalized older adults with moderate to very severe dementia, with a median age of 85.0 (interquartile range, IQR, 82.0–90.0), being higher in men (87.0 years, IQR 80.0–94.0) than in women (84.5 years, IQR 82.0–89.5). The BLT protocol consisted of 30-min morning sessions of 10,000 lux, Monday through Friday, for 4 weeks. The physiological parameters were recorded immediately before and after each session by pulse oximetry. Mood and behavior were assessed before, after, and during the sessions using the Interact scale. Post-session Interact scores showed a significant decrease in the items Tearful/sad and Talked spontaneously, and a significant increase in the items Enjoying self, active or alert, and Relaxed, content or sleeping appropriately. Interact scores during the sessions reflected a significant decrease in the speech-related items. Both physiological parameters changed positively from before to after sessions. Our results suggest that BLT provides immediate positive effects on mood, stimulation level, and physiological parameters, as well as a trend toward decreased speech. More robust research is needed to further explore the immediate impact of BLT. This study is registered with Clinicaltrials.gov (NCT04949984).

Mild Behavioral Impairment: A New At-Risk State for Alzheimer's Disease?

Improving our response to Alzheimer's disease (AD), including prevention and early intervention, is critical for maximizing healthy aging outcomes. Identifying older adults at highest risk for AD would provide an opportunity to offer support, plan for the future, and implement strategies to enhance cognitive and functional outcomes. The emergence of neuropsychiatric symptoms may be one indicator of early AD-related cognitive decline, but distinguishing symptoms from those due to other causes can be challenging. Mild behavioral impairment (MBI) describes an at-risk state for cognitive decline characterized by the late-life onset of neuropsychiatric symptoms. In this article, we discuss the current conceptualization of MBI, the potential for its characteristic neuropsychiatric symptoms to indicate risk for future cognitive decline, and present potential clinical implications.

Long-term implementation of the Managing Agitation and Raising QUality of lifE intervention in care homes: A qualitative study

OBJECTIVES

The dementia care home workforce receives little specific training. There are successful interventions, improving care outcomes, but it is unclear whether or how to sustain these effects. The Managing Agitation and Raising Quality of Life (MARQUE) intervention aimed to train care home staff to reduce resident agitation and improve quality of life. It was designed for sustainability, with implementation plans agreed with managers. MARQUE improves quality of life. In this separate study, we aimed to examine implementation around 2 years later.

METHODS AND DESIGN

We explored practice change since the intervention and considered current implementation of home-specific action plans, enablers or barriers, and perceived benefits or harms of implementation using semi-structured interviews with staff working in the trial homes who received the MARQUE intervention.

RESULTS

Six out of 10 intervention homes participated. We interviewed 25 staff, 20-30 months after the MARQUE study. In all homes, staff reported that at least one MARQUE component was sustained. Three themes emerged about sustained practice change: (i) communication, (ii) respect and understanding of roles, and (iii) ability to try new things. Notable changes included improved team working and feelings of competence, positive attitude to residents rather than blame for agitation and avoidance, and more pleasant activities. Leadership support was important.

CONCLUSIONS

It is possible to sustain some change over years in care homes. This study indicates factors which help or impede. These factors individually and together could lead to long-term improved quality of life of residents in homes where it is implemented and sustained.

The effects of bright light treatment on affective symptoms in people with dementia: a 24-week cluster randomized controlled trial

BACKGROUND

The majority of people with dementia have behavioral and psychological symptoms of dementia (BPSD), including depression, anxiety and agitation. These may be elicited or aggravated by disrupted circadian rhythms. Bright light treatment (BLT) is a promising non-pharmacological approach to the management of BPSD, but previous research has yielded mixed results.

METHODS

Eight nursing home dementia units (1 unit = 1 cluster) with 78 patients were invited to participate in a cluster randomized controlled trial from September 2017 to April 2018 investigating the effects of BLT on sleep and circadian rhythms (primary outcome) and BPSD (secondary outcome). Ceiling mounted LED-panels were installed in the intervention group (four units), providing light at 1000 lx and 6000 K (vertically at 1.2 m) between 10 a.m. and 3 p.m., with lower values in the mornings and evenings. Standard indoor light was used in the control group (four units). BPSD were assessed with The Cornell Scale for Depression in Dementia (CSDD) and the Neuropsychiatric Inventory Nursing Home Version (NPI-NH). Data collection took place at baseline and after 8, 16 and 24 weeks. Multilevel regression models with and without false discovery rate correction were used for the analysis, with baseline values and dementia stage entered as covariates.

RESULTS

Sixty-nine patients were included in the study at baseline. Compared to the control group, the intervention group had a larger reduction on the composite scores of both the CSDD (95% CI = - 6.0 - - 0.3) and the NPI-NH (95% CI = - 2.2 - - 0.1), as well as on the NPI-NH Affect sub-syndrome, and the CSDD Mood related signs sub-scale at follow-up after 16 weeks. With FDR correction, the group difference was significant on the CSDD Mood related signs sub-scale (95% CI = - 2.7 - - 0.8) and the NPI-NH Affect sub-syndrome (95% CI = - 1.6 - - 0.2). No differences were found between conditions at weeks 8 or 24.

CONCLUSION

Compared to the control condition, affective symptoms were reduced after 16 weeks in the group receiving BLT, suggesting BLT may be beneficial for nursing home patients with dementia.

Clinical profiles of people with dementia exhibiting with neuropsychiatric symptoms admitted to mental hospitals: A multicenter prospective survey in Japan

AIMS

Patients with severe behavioral and psychological symptoms of dementia (BPSD) are often admitted to mental hospitals, while, inpatient care could also lead to prolonged hospital stay. The present study aims to survey clinical profiles of patients who required inpatient treatment for BPSD, and then establish the criteria for introducing inpatient treatment through assessment by certified psychiatrists.

METHODS

We performed a prospective survey about clinical characteristics of people with dementia who required treatment of BPSD at 12 mental medical institutions. All patients were assessed by certified psychiatrists to determine the optimal treatment settings: outpatient or inpatient. The multivariate logistic regression analysis was performed to specify factors contributed to the judgement of clinicians. Subsequently, the receiver operating characteristic curve analysis was conducted to explore a score derived from the Neuropsychiatric Inventory to divide patients into outpatient or inpatient groups.

RESULTS

The present study included 386 patients, of which 242 were admitted to mental hospitals. BPSD were classified into four domains, and aggressive BPSD was significantly associated with assessment for inpatient treatment; the adjusted odds ratio was approximately 2 regardless of dementia severity. Furthermore, the composite score of agitation, irritability and aberrant behavior showed the highest area under the curve value (=0.706), which differentiated inpatients from outpatients with a sensitivity of 76% and a specificity of 54%.

CONCLUSIONS

Aggressive BPSD was the risk factor for inpatient treatment. The composite score of the Neuropsychiatric Inventory subdomain-related aggressive BPSD could be a screening tool to introduce inpatient treatment for BPSD. Geriatr Gerontol Int 2021; 21: 825-829.

Effect of acupressure on agitation in the elderly with dementia who receive institutional care: A pilot study

PURPOSE

This pilot study was carried out to determine the effect of acupressure on agitation in the elderly with dementia who receive institutional care.

METHODS

The study sample consisted of 38 elderly individuals (acupressure group [AG] = 19, usual-care group = 19). Acupressure application was performed on four points. The results were measured at the beginning (T₀ ), the week after acupressure was completed (T₁ ), and 2 weeks after acupressure was completed (T₂ ).

FINDINGS

The change in the total Cohen-Mansfield Agitation Inventory score across the groups at T₁ , T₂ , and T₃ was statistically significant in favor of AG.

PRACTICAL IMPLICATIONS

The acupressure used in this study can be used for managing agitation in the elderly with dementia.

Hearing Impairment and Cognition in an Aging World

With the increasing number of older adults around the world, the overall number of dementia cases is expected to rise dramatically in the next 40 years. In 2020, nearly 6 million individuals in the USA were living with Alzheimer's disease, the most common type of dementia, with anticipated growth to nearly 14 million by year 2050. This increasing prevalence, coupled with high societal burden, makes prevention and intervention of dementia a medical and public health priority. As clinicians and researchers, we will continue to see more individuals with hearing loss with other comorbidities including dementia. Epidemiologic evidence suggests an association between hearing loss and increased risk of dementia, presenting opportunity for targeted intervention for hearing loss to play a fundamental role in dementia prevention. In this discussion, we summarize current research on the association between hearing loss and dementia and review potential casual mechanisms behind the association (e.g., sensory-deprivation hypothesis, information-degradation hypothesis, common cause). We emphasize key areas of research which might best inform our investigation of this potential casual association. These selected research priorities include examination of the causal mechanism, measurement of co-existing hearing loss and cognitive impairment, and potential of aural rehabilitation. Addressing these research gaps and how results are then translated for clinical use is paramount for dementia prevention and overall health of older adults.

Uncontrolled Pain and Risk for Depression and Behavioral Symptoms in Residents With Dementia

OBJECTIVES

Limited cohort studies have assessed the association between uncontrolled pain and risk for behavioral and psychological symptoms of dementia (BPSDs). We conducted a longitudinal cohort study to examine whether associations exist between uncontrolled pain and risk for 2 common BPSDs-depression and behavioral symptoms-among long-term care (LTC) residents with Alzheimer disease and related dementia (ADRD).

DESIGN

This retrospective cohort study analyzed quarterly data from the 5% Medicare sample linked to Minimum Data Set (MDS) 3.0 between January 1, 2011, and December 31, 2015.

SETTING AND PARTICIPANTS

LTC residents aged 50 years or older with ADRD who had chronic pain and at least 2 quarterly MDS 3.0 assessments.

METHODS

LTC residents were followed up quarterly from first observed quarterly MDS 3.0 until first outcome event or last observed quarterly MDS 3.0. Uncontrolled pain was defined as numerical rating scale >4, verbal descriptor scale of moderate or severe pain, or ≥1 pain indicators on the Checklist of Nonverbal Pain Indicators. Depression was defined as ≥10 on the Patient Health Questionnaire 9; behavioral symptoms were defined as the presence of psychotic (delusions or hallucinations) or disruptive behaviors (rejection of care, or physical, verbal, or other aggressive behaviors). Generalized linear models (GLMs) with marginal structural modeling (MSM) stabilized weights were used to examine uncontrolled pain and outcome risk.

RESULTS

The incidence rate of depression and behavioral symptoms during follow-up was 9.4 and 23.1 per 100 resident-years, respectively. Results from the MSM-GLMs showed that LTC residents with uncontrolled pain had a higher risk than those with controlled pain for developing depression [hazard ratio 1.67, 95% confidence interval (CI) 1.54-1.81] and behavioral symptoms (hazard ratio 1.28, 95% CI 1.19-1.37).

CONCLUSIONS AND IMPLICATIONS

Uncontrolled pain was associated with elevated risk for depressive and behavioral symptoms in dementia, underscoring the importance of pain assessment and control among LTC residents with ADRD.

Managing Pain and Psychosis Symptoms in Nursing Home Patients: Results from a Cluster-Randomized Controlled Trial (COSMOS)

OBJECTIVES

In nursing homes (NHs), 30% to 60% of patients experience daily pain and >80% have dementia. This can lead to neuropsychiatric symptoms, including psychosis symptoms such as delusion. We investigated if there was a relationship between pain and psychosis symptoms over time. We also aimed to investigate the effect of a multicomponent intervention (COSMOS) on pain, psychosis symptoms, and analgesic prescription.

DESIGN

COSMOS is a cluster-randomized, single blinded, controlled trial. Each NH unit was defined as a cluster and randomized to either the COSMOS intervention or care as usual. The COSMOS intervention is a multicomponent intervention, consisting of staff training in communication, pain treatment, medication review, organization of activities, and safety. The intervention lasted for 4 months with a follow-up at month 9.

SETTING AND PARTICIPANTS

Sixty-seven units from 33 Norwegian NHs in 8 municipalities. The study included 723 patients aged ≥65 years, residing at the NH ≥2 weeks before inclusion. Patients with a life expectancy <6 months were excluded.

MEASURES

Pain was measured using the Mobilization-Observation-Behavior-Intensity-Dementia Pain Scale. Psychosis symptoms were measured using the Neuropsychiatric Inventory-NH version. Measurements were performed at baseline, and months 4 and 9.

RESULTS

Multilevel Mixed-Effect statistical analysis found that psychosis symptoms as a group (odds ratio [OR] 2.03, P = .009), and delusion (OR 2.12, P = .007) were associated with pain over time. No significant intervention effect on psychosis symptoms was observed. Compared with the control group, people with dementia in the intervention group experienced less musculoskeletal pain (β: -0.47, P = .047). Analgesic prescription was not affected by the intervention.

CONCLUSION AND IMPLICATIONS

Pain is associated with psychosis symptoms, and pain assessment should be done when making treatment decisions on psychosis symptoms in NH patients. The COSMOS intervention improved musculoskeletal pain in people with dementia, but not psychosis symptoms, and there is need for further studies on treatment of psychosis symptoms in NH patients.

A Digital Platform for Facilitating Personalized Dementia Care in Nursing Homes: Formative Evaluation Study

Background

Care personalization is key to the well-being of people with dementia according to person-centered care. With the development of the internet of things, a large quantity of personal data can be collected securely and reliably, which has the potential to facilitate care personalization for people with dementia. Yet, there are limited assistive technologies developed for this purpose, and the user acceptance of assistive technologies is low in nursing homes. Therefore, through a data-enabled design approach, a digital platform was developed for helping the care team in a nursing home to personalize dementia care, specifically in the management of behavioral and psychological dementia symptoms.

Objective

This study aimed to evaluate the digital platform in a real-life context with potential users from the following two aspects: (1) to explore if the digital platform could help with generating insights on the current state of each person with dementia and (2) to gather feedback on the digital platform from the care team.

Methods

The digital platform was deployed in the nursing home for 7 weeks and the data collected were visualized and presented to the care team via the digital platform. The visualizations were analyzed by the researchers for pattern detection. Meanwhile, the care team was asked to examine the visualizations and were interviewed for the following: (1) if any insights and actions were generated from the examination, (2) the usefulness of the digital platform, and (3) the improvements they would like to see.

Results

The data collected on the digital platform demonstrated its potential for pattern detection. Insights were generated by the care team and categorized into “client level,” “ward level,” and “team level.” The corresponding actions taken by the care team were classified into “investigation” and “implementation.” User acceptance varied across the care team, and three aspects of improvement for the digital platform were identified.

Conclusions

By evaluating the digital platform, this study gained insights on applying data-enabled design for personalizing dementia care; besides, it offers future researchers some recommendations on how to integrate assistive technologies in the nursing home context.

A mixed methods study on the manifestations of behavioural symptoms of dementia among veterans with and without posttraumatic stress disorder

AIMS

To explore how behavioural symptoms of dementia are manifested among veterans in residential long-term care settings, in the context of personal, interpersonal/social and environmental triggers and how the manifestations differ between veterans with and without posttraumatic stress disorder.

DESIGN

Secondary analysis using a mixed methods approach.

METHODS

We analysed text data from a stratified random sample of 66 cases derived from the programme evaluation dataset of the Staff Training in Assisted Living Residences-Veterans Health Administration (STAR-VA) intervention from 2013 to 2016, using framework analysis. The detailed behavioural assessment descriptions in this dataset are consistent with contemporary non-pharmacologic symptom management. Qualitative categories were converted to quantitative variables for two group comparisons.

RESULTS

Four patterns emerged linking specific types of triggers and behavioural symptoms: (1) unmet physical needs or emotional distress triggers non-aggressive behaviours; (2) unsolicited direct care approach triggers care refusal, resistance or combativeness; (3) interpersonal interactions interfering with self-direction trigger aggressive behaviours; and (4) uncontrolled stimulation from environments trigger non-aggressive behaviours. The organisational culture of care influenced how staff conceptualised behavioural symptoms. Veterans with co-existing posttraumatic stress disorder and dementia tended to exhibit rejection of care with aggression compared to those with dementia alone.

CONCLUSION

Contextualised accounts of behavioural symptoms of dementia revealed symptom heterogeneity, with different clusters of multi-level triggers arising from specific personal, interpersonal and environmental circumstances. Distinct patterns of symptom manifestations between veterans with and without posttraumatic stress disorder suggest a tailored approach is required to meet each veteran's unique biopsychosocial needs.

IMPACT

Classifying behavioural symptoms with their triggers rather than solely by behaviours provides important new information for developing person-centred, non-pharmacological interventions to improve outcomes for veterans with dementia. Multi-level interventions should be considered to meet veteran's needs that account for their earlier life history and current life circumstances.

Tetramethylpyrazine Alleviates Behavioral and Psychological Symptoms of Dementia Through Facilitating Hippocampal Synaptic Plasticity in Rats With Chronic Cerebral Hypoperfusion

Behavioral and psychological symptoms of dementia (BPSD) ubiquitously disturb all patients with dementia at some point in the disease course. Although a plethora of non-pharmacological and pharmacological methods targeting the relief BPSD have been developed, the therapeutic effect is still far from ideal. Here, a rat BPSD model combining the physiological changes with mental insults was successfully established. Meanwhile, our results indicated that TMP attenuated anxious behavior using an elevated plus maze (EPM) test, ameliorated recognitive ability and sociability through a novel object recognition test (NORT) and social interaction test (SIT), and improved learning and memory impairments via a Barnes maze in rats with bilateral common carotid arteries occlusion (BCCAO) plus chronic restraint stress (CRS). Given that hippocampus chronic cerebral hypoperfusion (CCH) always causes damage to the hippocampus, and the majority of cognitive impairments, behaviors, and stress responses are associated with pathology in the hippocampus including anxiety and depression, we paid attention to investigate the role of the hippocampus in BPSD. Our results indicated that Tetramethylpyrazine (TMP) attenuated anxiety and ameliorated recognitive ability, sociability, learning, and memory impairments due to alleviating dendritic and spine deficits, and upregulating the expression of synapse-related proteins (including PSD95, SYN, GAP43, SYP) in the hippocampus. We also found that the underlying mechanism was that TMP could activate the TrkB/ERK/CREB signaling pathway to promote synaptic remodeling in vivo and in vitro. Mechanically, the present study enlarges the therapeutic scope of TMP in neurodegenerative disorders and provides basic knowledge and feasible candidates for treating BPSD, particularly for vascular dementia.

Cannabis Use in Older Adults: A Perspective

The prevalence of cannabis use among older adults (aged 65 and above) for both recreational and medicinal purposes has significantly increased in recent years. Information regarding the safety of cannabis in this population is important since aging is associated with metabolic changes, multiple morbidities, increases in prescription medication use, and an overall decline in functioning. In this Perspectives article, we review special considerations pertinent to older adults-specifically, the impact of cannabis on cognition and on falls and injuries, its drug interactions, and its potential medicinal applications for treating the behavioral and psychological symptoms of dementia. Knowledge about the role of cannabis in brain health, injury risk, and drug interactions remains limited since the available evidence stems primarily from adolescent and young adult cohorts, plus a limited number of small observational studies with older adults. In terms of utilizing certain cannabinoids to treat the behavioral and psychological symptoms of dementia, some studies have found promising results, but because of the lack of consistency in the literature, it is premature to draw conclusions. Controlled research trials specifically with geriatric participants are needed to understand the effects of cannabis use in this vulnerable population.

Differences in Staff-Resident Interactions Between Male and Female Residents in Nursing Homes

The purpose of the current study was to describe gender differences in the quality of interactions between nursing home residents with behavioral and psychological symptoms of dementia and staff. Data from the Evidence Integration Triangle for Behavioral and Psychological Symptoms of Dementia (EIT-4-BPSD) implementation study were used for the current study. A total of 535 residents (72% female and 28% male) from 55 settings were included in the analyses. The highest percentage of interactions occurred in dining rooms (38.4%) and with nursing staff (68%). There were no significant differences in the quality of staff interactions with male or female residents. Most interactions were positive social (n = 360, 71% males, 66% females), positive care (n = 312, 60% males, 58% females), or neutral (n = 123, 25% males, 22% females). There were 31 (7% males, 6% females) negative protective and 23 (3% male, 5% female) negative restrictive interactions. Future work should focus on eliminating neutral and negative interactions across both genders and address whether the gender of staff is related to the quality of staff-resident interaction.

Agitation and apathy increase risk of dementia in psychiatric inpatients with late-onset psychiatric symptoms

BACKGROUND

A diagnosis of dementia in middle-aged and elder people is often complicated by physical frailty and comorbid neuropsychiatric symptoms (NPSs). Previous studies have identified NPSs as a risk factor for dementia. The aim of this study was to figure out to what extent individual NPS and certain demographic factors increased the risk of dementia in middle-aged and senior psychiatric inpatients.

METHODS

One hundred twenty-seven middle-aged and senior patients admitted to psychiatric wards for late-onset (age ≥ 50 years) psychiatric symptoms were included and categorized into dementia or non-demented psychiatric disorders (NDPD). The patients' demographic information and medical records were collected during the first hospitalization and subjected to statistical analyses.

RESULTS

41.73% of the registered psychiatric inpatients were diagnosed as dementia in which Alzheimer's disease (AD) was the dominant subtype. The NDPD group consisted of nine individual diagnoses, except for schizophrenia. The frequencies of dementia inpatients increased with first episode age while that of NDPD inpatients decreased with first episode age. In the enrolled inpatients, most of dementia patients were males while females accounted for a higher proportion of NDPD patients. 58.49% of enrolled dementia inpatients presented cognitive deficit (CD) as the initial symptom while the remaining 41.51% showed NPS as initial symptom. Of the 12 NPSs, agitation and apathy greatly and significantly increased risk of dementia in psychiatric inpatients with late-onset psychiatric symptoms.

CONCLUSIONS

These results added evidence that the demented patients admitted to psychiatric ward are more likely to be male, older first episode age, and have characteristic NPS including aberrant motor behavior (AMB), hallucinations, agitation, irritability and apathy. Further, this study emphasized the importance of agitation and apathy of NPSs functioning as risk factors of dementia in these inpatients.

Rationale, Design, and Methodology of a Prospective Cohort Study for Coping with Behavioral and Psychological Symptoms of Dementia: The RECage Project

BACKGROUND

Behavioral and psychological symptoms of dementia (BPSD) are quite challenging problems during the dementia course. Special Care Units for people with dementia (PwD) and BPSD (SCU-B) are residential medical structures, where BPSD patients are temporarily admitted, in case of unmanageable behavioral disturbances at home.

OBJECTIVE

RECage (REspectful Caring for AGitated Elderly) aspires to assess the short and long-term effectiveness of SCU-Bs toward alleviating BPSD and improving the quality of life (QoL) of PwD and their caregivers.

METHODS

RECage is a three-year, prospective study enrolling 500 PwD. Particularly, 250 community-dwelling PwDs presenting with severe BPSD will be recruited by five clinical centers across Europe, endowed with a SCU-B, for a short period of time; a second similar group of 250 PwD will be followed by six other no-SCU-B centers solely via outpatient visits. RECage's endpoints include short and long-term SCU-B clinical efficacy, QoL of patients and caregivers, cost-effectiveness of the SCU-B, psychotropic drug consumption, caregivers' attitude toward dementia, and time to nursing home placement.

RESULTS

PwD admitted in SCU-Bs are expected to have diminished rates of BPSD and better QoL and their caregivers are also expected to have better QoL and improved attitude towards dementia, compared to those followed in no-SCU-Bs. Also, the cost of care and the psychotropic drug consumption are expected to be lower. Finally, PwD followed in no-SCU-Bs are expected to have earlier admission to nursing homes.

CONCLUSION

The cohort study results will refine the SCU-B model, issuing recommendations for implementation of SCU-Bs in the countries where they are scarce or non-existent.

'We must have a new VIPS meeting soon!' Barriers and facilitators for implementing the VIPS practice model in primary health care

Introduction

Person-centred care is a philosophy of care rather than a method ready for implementation and utilisation in daily work. Internationally, few methods for the implementation of person-centred care have been widely adopted in clinical and care practice. In Norway, the VIPS practice model is a commonly used model for person-centred care implementation.

Method

Qualitative manifest content analysis was used. Managers and leaders in the municipalities, care institutions and domestic nursing care services were eligible for inclusion if their workplace had implemented the VIPS practice model and conducted the consensus meeting regularly for a minimum of 12 months. Seventeen respondents were included. Individual interviews were conducted either via FaceTime, Skype or telephone.

Results

Three global categories emerged describing the implementation process: (1) factors that impact the decision made at municipal level to implement person-centred care; (2) requirements for a good start at unit level and (3) factors that help to support the new routines in the unit. The categories were entwined; the results of one affected the results of the others. The informants from both domestic nursing care and institutions described the same factors as important for the implementation of the VIPS practice model.

Conclusion

To implement person-centred care by use of the VIPS practice model, the frontline staff need sufficient information about the rationale for implementing the model. The management’s vision and ethos of person-centred care must be followed by time set aside for staff training and regularly scheduled VIPS practice model consensus meetings. Head nurses are key to getting the new routines established and maintained and should be supported by the management.

Music playlists for people with dementia: Qualitative evaluation of a guide for caregivers

This study aimed to evaluate a set of guidelines for music use with people with dementia. A secondary aim was to identify challenges and barriers to implementation of music interventions by caregivers. Caregivers (n = 16) were interviewed after implementing a music listening programme based on the guidelines with 29 people with dementia in home-care and aged care facilities. Caregivers found the guidelines informative, easy to understand and use. Positive effects on mood, reduced agitation and reduced challenges to care were reported. Difficulties with technology and finding time to implement the music programme were identified. Results highlight the need for more research around appropriate technology and the streamlining of processes and procedures for aged care staff. Further iterations of the guidelines will need to address these issues and consider the differing needs of home-based carers and aged care providers separately.

Associations between COVID-19 and 30-day thromboembolic events and mortality in people with dementia receiving antipsychotic medications

BACKGROUND

Antipsychotic medications are frequently prescribed to people with dementia to manage behavioural and psychological symptoms. Using a global federated research network, the objectives were to determine: 1) if COVID-19 is associated with 30-day thromboembolic events and mortality for people with dementia receiving antipsychotic medications; and 2) if the proportion of people with dementia receiving antipsychotics is higher during the COVID-19 pandemic compared to 2019.

METHODS

A retrospective cohort study was conducted using TriNetX, a global federated health research network. The network was searched for people aged ≥ 65 years with dementia, COVID-19 and use of antipsychotics in the 30-days prior to COVID-19 recorded in electronic medical records between 20/01/2020 and 05/12/2020. These individuals were compared to historical controls from 2019 with dementia and use of antipsychotics in the 30-days before a visit to a participating healthcare organisation. Propensity score matching for age, sex, race, co-morbidities and use of antidepressants and anticonvulsants was used to balance cohorts with and without COVID-19.

RESULTS

Within the TriNetX network, 8414 individuals with COVID-19, dementia and use of antipsychotics and 31,963 historical controls were identified. After propensity score matching there were 8396 individuals with COVID-19 and 8396 historical controls. The cohorts were well balanced for age, sex, race, co-morbidities and use of antidepressants and anticonvulsants. The odds of 30-day thromboembolic events and all-cause mortality were significantly higher in adults with COVID-19 (Odds Ratios: 1.36 (95% confidence interval (CI): 1.21-1.52) and 1.93 (1.71-2.17), respectively). The number of people with dementia with a visit to a participating healthcare organisation was lower between 20/01/2020 and 05/12/2020 (n = 165,447) compared to the same period in 2019 (n = 217,391), but the proportion receiving antipsychotics increased from 14.7% (95%CI: 14.6-14.9%) to 16.4% (95%CI: 16.2-16.5%), P < .0001.

CONCLUSIONS

These findings add to the evidence base that during the COVID-19 pandemic there was an increase in the proportion of people with dementia receiving antipsychotics. The negative effects of antipsychotics in patients with dementia may be compounded by concomitant COVID-19.

Cause for Concern: Behavioral and Psychological Symptoms of Dementia in Delaware's Long-Term Care Facilities

INTRODUCTION

Much of the suffering and expense associated with treatment of persons with dementia (Major Neurocognitive Disorder) arises from associated noncognitive behavioral and psychological symptoms of dementia (BPSD). Although a consensus on the prevalence of BPSD is lacking, evidence suggests that most people with dementia will manifest one or more of these symptoms during the disorder's progression. BPSD raise the cost of care by leading to more frequent emergency room visits, more and longer hospitalizations, and earlier admission to long-term care facilities (LTCF). Treatment of BPSD presents a stressful challenge in LTCFs. We sought to investigate the care burden of BPSD in Delaware's LTCFs and to gather data that can inform management approaches.

METHODS

Using REDCap, we created an anonymous cross-sectional survey designed for completion by LTCF administrators. The Delaware Health Care Facilities Association (DHCFA) and Delaware's Division of Services for Aging and Adults with Physical Disabilities (DSAAPD) encouraged participation. A link to the survey was emailed to the administrators of 81 facilities in Delaware. The resulting data were evaluated using descriptive statistics.

RESULTS

Forty-four of the 81 facilities surveyed opened the survey link. Thirty-eight facilities answered at least some of the questions, and 19 surveys were fully completed. The reported average prevalence of BPSD among Delaware LTCF residents with dementia was 49.3% (SD 28.9). The five most frequently reported BPSD symptoms were anxiety, agitation, wandering, dysphoria/depression, and appetite/eating abnormalities. All facilities reported employing a spectrum of pharmacologic and non-pharmacologic management strategies. Twenty-two of 24 respondents (91.7%) reported that behavioral health consultation was available at their facilities and 18 of 20 respondents (90.0%) indicated that they provided training on how to manage residents with BPSD.

CONCLUSION

BPSD are a pervasive concern among Delaware's LTCFs. LTCFs may benefit from the development of training programs and dissemination of treatment guidelines incorporating evidence-based interventions and their implementation in managing BPSD to improve care, decrease stress on residents and caregivers, and reduce some avoidable health care costs.

FTLD Treatment: Current Practice and Future Possibilities

While behavioral variant frontotemporal dementia (bvFTD) and primary progressive aphasia (PPA) remain unrelenting and universally fatal conditions, there is a framework for supportive treatment in patients diagnosed with these frontotemporal dementia (FTD) syndromes and the larger spectrum of clinical syndromes associated with frontotemporal lobar degeneration (FTLD) pathology on autopsy. A managing physician has an important role in weighing therapeutic options, organizing caregiver support, and framing long-term expectations for patients and caregivers. Additionally, a dedicated neurologist may assist patients and caregivers in navigating a growing range of FTD research, including exciting opportunities in clinical therapeutic trials. This chapter will review current therapeutic options for patients with bvFTD and PPA and detail the landscape of potential new disease-modifying therapies targeting the pathophysiology or FTLD.

Attitudes, beliefs, and changing trends of cannabidiol (CBD) oil use among caregivers of individuals with Alzheimer's disease

OBJECTIVES

With the increasing popularity of CBD-based products, especially CBD oil, it is increasingly important to understand what motivates caregivers of individuals with Alzheimer's disease (AD) to use CBD oil as part of treatment. The purpose of this study was to identify the attitudes and beliefs of caregivers of individuals with AD toward CBD oil in Poland, to identify factors that might be associated with the decision to use CBD oil among caregivers, and to explore whether such a decision was discussed with a healthcare professional.

METHOD

A cross-sectional online survey was conducted in Poland. Participation in the study was entirely voluntary and completely anonymous. Caregivers (n = 73) were asked about their practices and attitudes regarding CBD oil.

RESULTS

The most common source of knowledge about CBD oil was an online support group for caregivers. The vast majority of caregivers found CBD to be effective in managing behavioral symptoms of AD and believed that healthcare professionals should offer CBD oil as a part of treatment. However, only 63 % (n = 46) reported consulting with their physician about using CBD oil. The study also demonstrated that some caregivers thought that CBD oil use was illegal in Poland and that their care-recipient may develop a dependence and withdrawal symptoms if they stopped using it.

CONCLUSIONS

The results of the study highlight the positive and negative perceptions among caregivers of people with AD. The study also emphasizes the importance of enhancing communication between caregivers and healthcare professionals to discuss the use of CBD oil in the treatment of individuals with AD.

Neuropsychiatric symptoms associated with family caregiver burden and depression

Alzheimer's disease (AD) is a progressive and degenerative condition affecting several cognitive areas, with a decline in functional abilities and behavioral changes.

OBJECTIVE

To investigate the association between neuropsychiatric symptoms in older adults with AD and caregiver burden and depression.

METHODS

A total of 134 family caregivers of older people diagnosed with AD answered a questionnaire with sociodemographic data and questions concerning the care context, neuropsychiatric symptoms, caregiver burden, and depressive symptoms.

RESULTS

Results revealed that 95% of older adults had at least one neuropsychiatric symptom, with the most common being: apathy, anxiety, and depression. Among the 12 neuropsychiatric symptoms investigated, 10 were significantly associated with caregiver burden, while 8 showed significant correlations with depressive symptoms.

CONCLUSIONS

Neuropsychiatric symptoms were related to caregiver burden and depressive symptoms. In addition to the older adult with AD, the caregiver should receive care and guidance from the health team to continue performing quality work.

Suicide risk within 1 year of dementia diagnosis in older adults: a nationwide retrospective cohort study

BACKGROUND

Although severe dementia could protect against suicide death by decreasing a person's capacity to implement a suicide plan, patients with early dementia may have better cognition, giving them more sustained insight into their disease and better enabling them to carry out a suicide plan. This study investigated suicide risk in older adults within 1 year of receiving a diagnosis of dementia.

METHODS

This study used National Health Insurance Service Senior Cohort data and included 36 541 older adults with newly diagnosed dementia (a Mini-Mental State Examination score ≤ 26 and a Clinical Dementia Rating score ≥ 1 or a Global Deterioration Scale score ≥ 3), including Alzheimer disease, vascular dementia and other/unspecified dementia, from 2004 to 2012. We selected older adults without dementia through 1:1 propensity-score matching using sex, age, comorbidities and index year, with follow-up throughout 2013. We estimated adjusted hazard ratios (AHRs) of suicide deaths within 1 year after diagnosis using a time-dependent Cox proportional hazards model.

RESULTS

We verified 46 suicide deaths during the first year after a dementia diagnosis. Older adults with dementia had an increased risk of suicide death compared to those without dementia (AHR 2.57; 95% confidence interval [CI] 1.49-4.44). Older adults with Alzheimer disease (AHR 2.50; 95% CI 1.41-4.44) or other/unspecified dementia (AHR 4.32; 95% CI 2.04-9.15) had an increased risk of suicide death compared to those without dementia. Patients with dementia but without other mental disorders (AHR 1.96; 95% CI 1.02-3.77) and patients with dementia and other mental disorders (AHR 3.22; 95% CI 1.78-5.83) had an increased risk of suicide death compared to patients without dementia. Patients with dementia and schizophrenia (AHR 8.73; 95% CI 2.57-29.71), mood disorders (AHR 2.84; 95% CI 1.23-6.53) or anxiety or somatoform disorders (AHR 3.53; 95% CI 1.73-7.21), respectively, had an increased risk of suicide death compared to patients with those conditions but without dementia.

LIMITATIONS

This study examined only elderly patients in South Korea, a population with a substantially higher suicide rate than the global population. Caution must be exercised when generalizing the results to populations with dissimilar backgrounds.

CONCLUSION

Patients with dementia had an increased risk of suicide death within 1 year after diagnosis compared to those without dementia.

Implementing Silent Disco Headphones in a Hospital Unit: A Qualitative Study of Feasibility, Acceptance, and Experience Among Patients and Staff

INTRODUCTION

Music is so widely available and inexpensive in the modern world; it is a common option for stress reduction, comfort and enjoyment. Silent disco headphones are used among young people; however, no study has yet investigated whether it is feasible to use these headphones to support mental health and well-being among older people with dementia in hospital settings.

OBJECTIVE

The study's main objective is to explore whether music delivered by silent disco headphones was feasible and acceptable to a sample of inpatients staying in an older adult mental health unit of a large urban hospital.

METHODS

We employed a video-ethnographic design in data collection, including conversational interviews and observations with video recording among ten patient participants in a hospital unit. A focus group was conducted with ten hospital staff on the unit.

RESULTS

Our analysis identified three themes that represented experiences of patients and staff: (1) perceived usefulness, (2) perceived ease of use, and (3) attitude. Patient participants reported the music delivered by the headphones brought positive benefits. Witnessing the positive effects on patients influenced the staff's view of how music could be used in the clinical setting to support patients' well-being.

CONCLUSIONS

The music delivered by the silent disco headphones in an older adult mental health unit was found to be an acceptable and feasible intervention for patients. Leadership support is identified as an enabling factor in supporting technology adoption in the clinical setting. The findings can be used to inform practice development and future research.

Current Psychotropic Medication Use and Contributing Factors Among Nursing Home Residents With Cognitive Impairment

This study described current use and predictors of psychotropics among residents with moderate to severe cognitive impairment. This was a secondary data analysis using baseline data from the first 341 residents in an ongoing trial. Predictive measures included age, gender, race, depressive symptoms, agitation, resistiveness to care, depression, cognition, pain, comorbidities, facility factors, and state. Overall 63% (n = 211) received at least one psychotropic medication, 16% (n = 52) an anti-seizure medication, 23% (n = 77) an anxiolytic, 30% (n = 99) an antidepressant, 2% (n = 8) a sedative hypnotic, 28% (n = 93) an antipsychotic medication, and 9% (n = 29) an opioid. Testing of models explained 9% to 15% of psychotropic medication use. There were high rates of psychotropic medication use and a limited association between demographic factors, behavioral symptoms, and psychotropic medication use. Continued research is needed to explore the impact of deprescribing, person-centered behavioral interventions, and beliefs of providers on psychotropic medication use.
