The influence of caregivers and behavioral and psychological symptoms on nursing home placement of persons with Alzheimer's disease: A matched case-control study

Progress in Pharmacologic Management of Neuropsychiatric Syndromes in Neurodegenerative Disorders: A Review

Importance

Neuropsychiatric syndromes (NPSs) are common in neurodegenerative disorders (NDDs); compromise the quality of life of patients and their care partners; and are associated with faster disease progression, earlier need for nursing home care, and poorer quality of life. Advances in translational pharmacology, clinical trial design and conduct, and understanding of the pathobiology of NDDs are bringing new therapies to clinical care.

Observations

Consensus definitions have evolved for psychosis, agitation, apathy, depression, and disinhibition in NDDs. Psychosocial interventions may reduce mild behavioral symptoms in patients with NDD, and pharmacotherapy is available for NPSs in NDDs. Brexpiprazole is approved for treatment of agitation associated with Alzheimer disease dementia, and pimavanserin is approved for treatment of delusions and hallucinations associated with psychosis of Parkinson disease. Trials are being conducted across several of the NDDs, and a variety of mechanisms of action are being assessed for their effect on NPSs.

Conclusions and Relevance

Detection and characterization of NPSs in patients with NDDs is the foundation for excellent care. New definitions for NPSs in NDDs may inform choices regarding clinical trial populations and translate into clinical practice. Psychosocial and pharmacologic therapies may reduce behavioral symptoms and improve quality of life for patients and caregivers. Approved agents may establish regulatory precedents, demonstrate successful trial strategies, and provide the foundation for further advances in treatment development.

Racial/Ethnic Differences in Risk Factors Associated With Severe COVID-19 Among Older Adults With ADRD

OBJECTIVE

To examine racial/ethnic differences in risk factors, and their associations with COVID-19-related outcomes among older adults with Alzheimer's disease and related dementias (ADRD).

DESIGN

Observational study.

SETTING AND PARTICIPANTS

National Medicare claims data and the Minimum Data Set 3.0 from April 1, 2020, to December 31, 2020, were linked in this study. We included community-dwelling fee-for-service Medicare beneficiaries with ADRD, diagnosed with COVID-19 between April 1, 2020, and December 1, 2020 (N = 138,533).

METHODS

Two outcome variables were defined: hospitalization within 14 days and death within 30 days of COVID-19 diagnosis. We obtained information on individual sociodemographic characteristics, chronic conditions, and prior health care utilization based on the Medicare claims and the Minimum Dataset. Machine learning methods, including lasso regression and discriminative pattern mining, were used to identify risk factors in racial/ethnic subgroups (ie, White, Black, and Hispanic individuals). The associations between identified risk factors and outcomes were evaluated using logistic regression and compared across racial/ethnic subgroups using the coefficient comparison approach.

RESULTS

We found higher risks of COVID-19-related outcomes among Black and Hispanic individuals. The areas under the curve of the models with identified risk factors were 0.65 to 0.68 for mortality and 0.61 to 0.62 for hospitalization across racial/ethnic subgroups. Although some identified risk factors (eg, age, gender) for COVID-19-related outcomes were common among all racial/ethnic subgroups, other risk factors (eg, hypertension, obesity) varied by racial/ethnic subgroups. Furthermore, the associations between some common risk factors and COVID-19-related outcomes also varied by race/ethnicity. Being male was related to 138.2% (95% CI: 1.996-2.841), 64.7% (95% CI: 1.546-1.755), and 37.1% (95% CI: 1.192-1.578) increased odds of death among Hispanic, White, and Black individuals, respectively. In addition, the racial/ethnic disparity in COVID-19-related outcomes could not be completely explained by the identified risk factors.

CONCLUSIONS AND IMPLICATIONS

Racial/ethnic differences were detected in the likelihood of having COVID-19-related outcomes, specific risk factors, and relationships between specific risk factors and COVID-19-related outcomes. Future research is needed to elucidate the reasons for these differences.

Highlighting the value of Alzheimer's disease-focused registries: lessons learned from cancer surveillance

Like cancer, Alzheimer's disease and related dementias (ADRD) comprise a global health burden that can benefit tremendously from the power of disease registry data. With an aging population, the incidence, treatment, and mortality from ADRD is increasing and changing rapidly. In the same way that current cancer registries work toward prevention and control, so do ADRD registries. ADRD registries maintain a comprehensive and accurate registry of ADRD within their state, provide disease prevalence estimates to enable better planning for social and medical services, identify differences in disease prevalence among demographic groups, help those who care for individuals with ADRD, and foster research into risk factors for ADRD. ADRD registries offer a unique opportunity to conduct high-impact, scientifically rigorous research efficiently. As research on and development of ADRD treatments continue to be a priority, such registries can be powerful tools for conducting observational studies of the disease. This perspectives piece examines how established cancer registries can inform ADRD registries' impact on public health surveillance, research, and intervention, and inform and engage policymakers.

The longitudinal patterns of psychotropic drug prescriptions for subpopulations of community-dwelling older people with dementia: electronic health records based retrospective study

BACKGROUND

Studies focusing on patterns of psychotropic drug prescriptions (PDPs) for subpopulations of community-dwelling older people with dementia are lacking.

OBJECTIVE

The aim of this study was to identify the longitudinal patterns of PDPs in subpopulations.

METHODS

This retrospective study used electronic health records from general practitioners (GPs) in the Netherlands. People (N = 1278) firstly diagnosed with dementia between 2013 and 2015, aged 65 years or older, were selected and categorized into four subpopulations: community-dwelling (CD) group throughout follow-up, ultimately admitted to nursing homes (NH) group, ultimately died (DIE) group, and ultimately deregistered for unclear reasons (DeR) group. Generalised estimating equations were used to estimate the patterns of psychotropic drug prescriptions, after the diagnosis of dementia for a five-year follow-up, and 0-3 months before institutionalisation or death.

RESULTS

Over the five-year follow-up, antipsychotic prescriptions increased steadily in CD (OR = 1.07 [1.04-1.10]), NH (OR = 1.10 [1.04-1.15]), and DIE (OR = 1.05 [1.02-1.08]) groups. Similarly, prescriptions of antidepressants also showed upward trends in CD (OR = 1.04 [1.02-1.06]), NH (OR = 1.10 [1.02-1.18]), and DIE (OR = 1.04 [1.00-1.08]) groups. The other psychotropic drugs did not show clear changes over time in most of the subpopulations. In the three months before institutionalisation, antipsychotic prescriptions increased (OR = 2.12 [1.26-3.57]) in the NH group compared to prior periods. Likewise, before death, prescriptions of antipsychotics (OR = 1.74 [1.28-2.38]) and hypnotics and sedatives (OR = 2.11 [1.54-2.90]) increased in the DIE group, while anti-dementia drug prescriptions decreased (OR = 0.42 [0.26-0.69]).

CONCLUSIONS

After community-dwelling older people are diagnosed with dementia, all subpopulations' prescriptions of antipsychotics and antidepressants increase continuously during the follow-up. While we cannot judge whether these prescriptions are appropriate, GPs might consider a more reluctant use of psychotropic drugs and use alternative psychosocial interventions. Additionally, antipsychotic prescriptions rise considerably shortly before institutionalisation or death, which might reflect that older people experience more neuropsychiatric symptoms during this period.

"The Sun Came Up Because You Got Here…": A Qualitative Exploration of Person-Centered Care Strategies Used by Adult Day Care Centers to Manage Behavioral and Psychological Symptoms of Dementia

In order to reduce care partner strain and support aging in place for people living with Alzheimer's Disease and Alzheimer's Disease Related Dementias (AD/ADRD), adult day centers (ADCs) must manage behavioral and psychological symptoms of dementia (BPSD). The purpose of this paper is to identify person-centered care strategies used by center staff to manage BPSD. Six focus groups with center staff (n = 31) were conducted. Data were analyzed using directed content analysis guided by Kitwood's conceptual approach to cultivating personhood in dementia care. Themes were identified and organized within Kitwood's framework. The results demonstrate that staff incorporate evidence-based person-centered approaches to AD/ADRD care that align with Kitwood's principles of comfort, attachment, inclusion, and identity. Staff individualize their approach to people with AD/ADRD within a group setting. They monitor, engage, socially stimulate, and, when needed, de-stimulate them. Centers are flexible social environments with underrecognized expertise managing BPSD using person-centered approaches.

Association between behavioural and psychological symptoms of dementia and residence status in patients with Alzheimer's disease

BACKGROUND

Examining the relationship between the behavioural and psychological symptoms of dementia (BPSD) and residence status is crucial to improving BPSD and reducing the burden on caregivers. However, studies on how BPSD differ between individuals living at home and those in institutional settings are lacking. We conducted a questionnaire survey among healthcare providers (HCPs) involved in dementia care and nursing to clarify the characteristics of BPSD by residence status in patients with Alzheimer's disease (AD) living at home or in facilities.

METHODS

We sent questionnaires to HCPs and asked them to answer questions on up to five cases that needed treatment for BPSD and who received long-term care insurance services from 1 April 2016 to 31 March 2017. Responses were received for 371 cases, of which 130 diagnosed with AD were analyzed. The patients were divided into two groups: patients with AD living at home (home care group) and patients with AD living in facilities (facility care group). A Chi-square test was used to identify differences between the two groups. A binomial logistic regression analysis was also conducted to clarify the association between residence status and BPSD.

RESULTS

Of the 130 patients, 72 lived at home (home care group) and 58 resided in facilities (facility care group). None of the background factors was significantly different between the two groups. The Chi-square test indicated that sleep disturbance was significantly more common in the facility care group (60.3% in the facility care group vs. 33.3% in the home care group, P = 0.003), while the logistic regression analysis indicated that sleep disturbance was significantly associated with residence status (odds ratio: 2.529, P = 0.038).

CONCLUSIONS

Sleep disturbances were more frequently observed among patients with AD living in institutions than among those living in their homes.

Neighborhood characteristics and dementia symptomology among community-dwelling older adults with Alzheimer's disease

Background

Neuropsychiatric symptoms (NPSs) lead to myriad poor health outcomes among individuals with Alzheimer's disease (AD). Prior studies have observed associations between the various aspects of the home environment and NPSs, but macro-level environmental stressors (e.g., neighborhood income) may also disrupt the neuronal microenvironment and exacerbate NPSs. Yet, to our knowledge, no studies have investigated the relationship between the neighborhood environment and NPSs.

Methods

Using 2010 data among older adults with AD collected from a sample of the South Carolina Alzheimer's Disease Registry, we estimated cross-sectional associations between neighborhood characteristics and NPSs in the overall population and by race/ethnicity. Neighborhood measures (within a 1/2-mile radius of residence) came from the American Community Survey and Rural Urban Commuting Area Code. We categorized median household income into tertiles: < $30,500, $30,500-40,000, and > $40,000, and rurality as: rural, small urban, and large urban. Residential instability was defined as the percent of residents who moved within the past year. NPSs were defined using the Neuropsychiatric Inventory Questionnaire that included the composite measure of all 12 domains. Adjusting for age, sex/gender, race/ethnicity, and caregiver educational attainment, we used negative binomial regression to estimate prevalence ratios (PR) and 95% confidence intervals (CI) for NPSs by neighborhood characteristics.

Results

Among 212 eligible participants, mean age was 82 ± 8.7 years, 72% were women, and 55% non-Hispanic (NH)-Black. Individuals with AD living in < $30,500 vs. > $40,000 income neighborhoods had a 53% (PR = 1.53; 95% CI = 1.06-2.23) higher prevalence of NPSs while individuals living in rural vs. large urban neighborhoods had a 36% lower prevalence of NPSs (PR = 0.64; 95% CI = 0.45-0.90), after adjustment. We did not observe an association between residential instability and NPSs (PR = 0.92; 95% CI = 0.86-1.00); however, our estimates suggested differences by race/ethnicity where NH-White older adults living in residential instable areas had lower NPSs (PR = 0.89; 95% CI = 0.82-0.96) compared to NH-Black older adults (PR = 0.96; 95% CI = 0.86-1.07).

Discussion

Across racial/ethnic groups, individuals with AD had more symptomology when living in lower income areas. Pending replication, intervention efforts should consider resource allocation to high-need neighborhoods (e.g., lower income), and studies should investigate underlying mechanisms for this relationship.

Stressors and Acceptability of Services Among Black Caregivers of Persons With Memory Problems

The purpose of the current study was to identify stressors of Black family caregivers (FCGs) of persons with memory problems (PWMPs), services of interest, and barriers to use of these services. Black FCGs were recruited from the Alzheimer's family program at the University of Alabama at Birmingham and affiliated geriatric clinics, media sources, and word-of-mouth referrals. Of 38 Black FCGs interviewed, 26 (68%) were female, 18 (47%) were employed, and 21 (55%) were adult children. Average age of FCGs was 52.11 years. Mean scores for the AD8 Dementia Screening Scale (mean = 13.95, SD = 2.17) and Clinical Dementia Scale Sum of Boxes (mean = 7.29, SD = 0.87) were higher than clinical cutoffs. The most common stressors for Black FCGs were PWMPs' inability to remember who they were, managing care recipients' financial affairs, and managing PWMPs' comorbid conditions. FCGs were most interested in educational material regarding treatment and diagnosis (55.3%), caring for people with dementia (52.6%), understanding dementia (52.6%), and financial/legal services (52.6%). FCGs stated that transportation difficulties and the need for a relief person were barriers to use of services. Results suggest that Black FCGs may be more likely to participate in interventions that include virtual conferencing modalities. [Journal of Gerontological Nursing, 48(6), 13-18.].

The Diagnosis of Schizophrenia Among Nursing Home Residents With ADRD: Does Race Matter?

OBJECTIVE

To examine racial differences in the frequency of schizophrenia diagnosis codes used among nursing home (NH) residents with Alzheimer's Disease and Related Dementias (ADRD), pre and post the implementation of public reporting of antipsychotic use in NHs.

METHODS

The 2011-2017 Minimum Data Set and Medicare Master Beneficiary Summary File were linked. We identified long-stay NH residents (i.e., those who had quarterly or annual assessments) with ADRD aged 55 years and older (N = 7,734,348). Outcome variable was defined as the diagnosis of schizophrenia documented in the MDS assessments. Main variables of interest included individual race (black versus white), the percent of blacks in a NH and time trend. Multivariate regressions were estimated.

RESULTS

The frequency of schizophrenia diagnosis codes among NH residents with ADRD steadily increased over the study period, and blacks experienced a greater increase than their white counterparts. For example, the overall likelihood of having schizophrenia diagnosis increased 1.9 percentage points (95% confidence interval [CI]: 0.019, 0.020, p < 0.01) from 2011 to 2017 among whites, while blacks had an addition 1.3 percentage points increase (95% CI: 0.011, 0.015, p < 0.01). The increase in the likelihood of having schizophrenia diagnosis code was higher in NHs with higher percent of blacks: the increase from 2011 to 2017 was 2.6 percentage point (95% CI: 0.023, 0.029, p < 0.01) higher in NHs with the highest percent of blacks, compared to NHs with lowest percent of blacks. Racial differences in the growth of schizophrenia diagnosis also existed within a NH after accounting for NH factors.

CONCLUSION

Following the implementation of public reporting of antipsychotic use in NH, black residents experienced a greater increase in the likelihood of having schizophrenia diagnosis than white NH residents. NHs with a higher proportion of blacks had a greater increase in schizophrenia diagnosis, and blacks experienced an increased likelihood of schizophrenia diagnosis than whites within a NH. Further research is needed to determine a causal relationship between the federal policy mandating public reporting and disparities in schizophrenia diagnostic coding.

The effects of caregiver characteristics on behavioral and psychological symptoms of dementia of patients with dementia

OBJECTIVE

To determine the association between caregiver characteristics and behavioral and psychological symptoms of dementia (BPSD) in patients with dementia (PWD) in a Taiwanese community-dwelling population.

METHODS

This cross-sectional study was conducted using the data of 190 patients with Alzheimer's disease/dementia and 190 informal matched caregivers in Taiwan. BPSD were examined using the Neuropsychiatric Inventory-Questionnaire (NPI-Q). Correlation and regression analyses were used to explore associations between caregiver characteristics and the presence, severity, and distress of NPI-Q items.

RESULTS

Only spouse primary caregiver was positively associated with presence of delusions in PWD. Caregiver education was positively correlated to severity of hallucinations, agitation/aggression, and apathy/indifference in PWD, while child primary caregiver was positively related to severity of disinhibition in PWD but negatively related to severity of anxiety in PWD. Spouse primary caregiver was positively related to severity of anxiety and appetite/eating in PWD while sole primary caregiver was positively related to severity of anxiety and nighttime behaviors in PWD. Caregiver education was positively correlated to distress of agitation/aggression in caregivers while child primary caregiver was positively related to distress of disinhibition in caregivers. Spouse primary caregiver was positively related to distress of anxiety and appetite/eating in caregivers while spouse caregiver was positively related to distress of nighttime behaviors in caregivers.

CONCLUSIONS

Caregiver education, child and spouse primary caregiver were relevant to severity of PWD and distress of caregivers of BPSD. It is suggested that healthcare professionals provide caregivers with proper individualized interventions based on these results to enhance caring quality.Key pointsCaregiver education was positively correlated to severity of hallucinations, agitation/aggression, and apathy/indifference, and distress of agitation/aggression.Child primary caregiver was positively related to severity and distress of disinhibition but negatively related to severity of anxiety.Spouse primary caregiver was positively related to severity and distress of anxiety and appetite/eating, and distress of nighttime behaviors.

Care home residents with dementia: Prevalence, incidence, and associations with sleep disturbance in an English cohort study

INTRODUCTION

People living with dementia in care homes often have sleep disturbances, but little is known about incidence and importance.

METHODS

We interviewed 1483 participants in 97 care homes and report prevalence, 1-year incidence, and baseline associations of clinically significant sleep disturbance in people with dementia.

RESULTS

Baseline prevalence of clinically significant sleep disturbance was 13.7% (200/1460); 31.3% (457/1462) had them at least once over 16 months. One-year incidence was 25.2%. At baseline, residents with sleep disturbance had lower quality of life (mean difference -4.84; 95% confidence interval [CI] -6.53 to -3.16) and were more frequently prescribed sleep medications (odds ratio 1.75; CI 1.17 to 2.61) than other residents.

DISCUSSION

Approximately one-third of care home residents with dementia have or develop sleep disturbances over 1 year. These are associated with lower quality of life and prescription of sedatives, which may have negative outcomes; therefore, it is important to develop effective treatments.

Development and assessment of a brief screening tool for psychosis in dementia

INTRODUCTION

Hallucinations and delusions (H+D) are common in dementia, but screening for these symptoms-especially in busy clinical practices-is challenging.

METHODS

Six subject matter experts developed the DRP3™ screen, a novel valid tool to detect H+D in dementia, assessed its content validity through alignment with DRP reference assessments (Scale for the Assessment of Positive Symptoms-Hallucinations + Delusions, Neuropsychiatric Inventory-Questionnaire, International Psychogeriatric Association Criteria), and retrospectively investigated its ability to detect H+D in HARMONY trial (NCT03325556) enrollees.

RESULTS

All items from three reference assessments demonstrated significant agreement with the DRP3 screen among raters (P < .0001). Retrospectively applying the DRP3 screen to HARMONY identified all (N = 392) trial enrollees.

DISCUSSION

The DRP3 screen, comprising three yes/no questions, is a content-valid tool for detecting H+D in dementia that aligned with current reference assessments and successfully identified trial participants when retrospectively applied to a completed trial. Within busy practice constraints, the DRP3 screen provides a brief tool for sensitive detection of H+D in patients with dementia.

A pragmatic trial testing a tailored non pharmacologic therapies on nocturnal behavioral and psychological symptoms associated with dementia

We compared the efficacy of tailored non pharmacological therapies (NPT) on specific nocturnal behavioral and psychological symptoms of dementia (BPSD). This retrospective 1-year study included 84 older dependent patients institutionalized in 7 long-term care home. Dedicated assistants, who were taught by experts how to use NPT, were asked to record the occurrence of each BPSD episode, to choose a given NPT on the basis of their knowledge of the patient and the type of BPSD and to estimate its efficacy. Wandering was the most prevalent BPSD followed by agitation/aggression and screaming. The most used therapy was cognitive stimulation, followed by multisensory stimulation, reminiscence and Montessori-based. Regarding wandering, multisensory stimulation was found to be the most efficacious NPT significantly different from Montessori-based, cognitive stimulation or reminiscence. With regards to agitation/aggression or screaming, Montessori-based was found to be the most efficacious NPT significantly different from multisensory stimulation, reminiscence and cognitive stimulation.

HCBS Service Spending and Nursing Home Placement for Patients With Alzheimer's Disease and Related Dementias: Does Race Matter?

OBJECTIVES

We examined the extent to which home and community-based services (HCBS) spending affected the likelihood of nursing home (NH) placement among black and white HCBS users with Alzheimer's disease and related dementias (ADRD).

METHODS

The study population included new HCBS users with ADRD between 2010 and 2013 (N = 1,046,200).

RESULTS

We found that a one hundred dollar increase in monthly HCBS spending was associated with a 0.3 percentage points decrease in the NH placement rate among Whites, but a 0.3 percentage points increase in the NH placement rate among Blacks. The overall NH placement rate was 68.2% and 56.7% for Whites and Blacks, respectively.

DISCUSSION

A higher HCBS spending was associated with a decreased likelihood of NH placements for Whites but not for Blacks. It is important to understand how states' HCBS expansion efforts influence Blacks and Whites with ADRD so that resources can be tailored to communities with different race-mix.

Satisfaction, utilization, and feasibility of a telehealth intervention for in-home dementia care support: A mixed methods study

BACKGROUND

Technology can enhance support for families caring for persons living with dementia but must be acceptable to be adopted. The FamTechCare clinical trial engaged caregivers in video recording care encounters that were reviewed by an expert panel who provided tailored feedback. The intervention reduced caregiver depression and improved caregiver competence. This mixed methods study reports on caregiver satisfaction and utilization of the intervention and expert panel evaluation of the intervention.

METHODS

A convergent parallel mixed methods design was used to evaluate the satisfaction, usability, and feasibility of the FamTechCare intervention. In the multisite randomized controlled trial, caregiver-person living with dementia dyads were randomized to the FamTechCare video support or attention control telephone support groups. Caregivers completed a satisfaction survey at the completion of the 3-month trial. Utilization was evaluated using the number and duration of videos submitted and calls received by caregivers. Relationships between participant characteristics and their satisfaction and utilization were evaluated. Feasibility of the intervention was assessed through content analysis of interviews with the expert panel.

RESULTS

The majority of caregivers in both groups reported benefits from participation. More FamTechCare caregivers found the interventionist support to be helpful (p = 0.001) and effective (p = 0.020) compared to attention control caregivers. FamTechCare caregivers of persons with more severe dementia were more likely to report that video recording intruded on their privacy (p = 0.050). Caregiver age, gender, education, dyad relationship, rural status, and type and severity of dementia were not associated with ratings of acceptability, ease of use, or intervention utilization. The expert panel described the FamTechCare intervention as useful and identified adaptations to enhance feasibility.

CONCLUSION

Regardless of age, gender, and relationship, caregivers found the intervention acceptable and easy to use and rated the expert feedback as effective in addressing care challenges. Further adaptation may be needed for FamTechCare to be readily implemented.

Real-World Medication Treatment Patterns for Long-Term Care Residents with Dementia-Related Psychosis

Objectives: This study evaluated treatment patterns and factors associated with medication treatment changes in residents with dementia-related psychosis in a long-term care (LTC) setting. Methods: A retrospective database cohort study was conducted using the national PharMerica^® database and included dementia residents with or without incident psychosis. Treatment patterns were assessed and a multivariate logistic regression model was used to identify factors associated with any treatment change (discontinuation, switch, or sporadic use) in dementia-related psychosis therapy. Results: Among 11,921 residents with incident dementia-related psychosis, 11,246 (94.3%) were prescribed ≥1 index medication to treat psychosis, including 77.3% who received ≥1 typical or atypical antipsychotic. Treatment change was evaluated during the post-index period: 38.7% of residents with dementia-related psychosis discontinued treatment, 13.9% switched treatments, and 7.9% had sporadic use. Factors associated with treatment change were age ≥65 years, Medicare insurance, and comorbid conditions (anemia, coronary heart disease, diabetes, falls, depression, hypertension, or hyperlipidemia) during the pre-index period. Discussion: Approximately 60% of dementia-related psychosis LTC residents experienced a medication treatment change. This treatment change was associated with higher age and higher comorbidities. Medications that treat symptoms of dementia-related psychosis without adding to safety concerns are needed to facilitate long-term, consistent treatment.

Neighborhood Characteristics and the Mental Health of Caregivers Cohabiting with Care Recipients Diagnosed with Alzheimer's Disease

While studies have documented the influence of caregiver and care recipient factors on caregiver health, it is important to address the potential impact of neighborhood contexts. This study estimated the cross-sectional associations between neighborhood characteristics and mental health among caregivers cohabiting with Alzheimer's disease care recipients that were experiencing severe or non-severe neuropsychiatric symptoms (NPSs) (e.g., aggression/anxiety). We obtained data collected in 2010 on caregivers and care recipients (n = 212) from a subset of South Carolina's Alzheimer's Disease Registry. Neighborhood measures (within 1 mile of the residence) came from the American Community Survey and the Rural-Urban Commuting Area Code. We categorized the neighborhood median household income into tertiles, namely, "low" (<$31,000), "medium" ($31,000-40,758), and "high" (>$40,758), and rurality as "large urban," "small urban," and "rural." We used negative binomial regression to estimate the prevalence ratios (PRs) and 95% confidence intervals (CIs) for caregiver mental health using neighborhood characteristics. The mean age was 58 ± 10.3 years, 85% were women, and 55% were non-Hispanic Black. Among the caregivers cohabiting with a recipient experiencing severe NPS, higher distress was experienced by caregivers living in low- (PR = 1.61 (95% CI = 1.26-2.04)) and medium- (PR = 1.45 (95% CI = 1.17-1.78)) vs. high-income neighborhoods after an adjustment. These results suggest that neighborhood characteristics may amplify other social stressors experienced by caregivers.

Effects of a Video-based Intervention on Caregiver Confidence for Managing Dementia Care Challenges: Findings from the FamTechCare Clinical Trial

OBJECTIVES

The Supporting Family Caregivers with Technology trial tested the FamTechCare video support intervention against telephone support. Dementia caregivers' video-recorded challenging care encounters and an interdisciplinary team provided tailored feedback. This paper reports on the effects of the intervention on caregiver confidence in managing priority challenges, a secondary outcome of this non-blinded parallel randomized controlled trial.

METHODS

Caregiver/person living with dementia dyads were randomized to the experimental FamTechCare video support (n = 43) or attention control telephone support (n = 41) groups. Caregivers providing in-home care to a person living with mild or more severe dementia were eligible. Caregivers identified three priority challenges using the Caregiver Target Problems Questionnaire and rated the frequency and severity of each challenge and their confidence managing the challenge at baseline and 3-months. Challenges were classified using the FamTechCare Technology-supported Dementia Care Typology. Effects on confidence were compared between groups using the Wilcoxon rank-sum test and within groups using the Wilcoxon signed-rank test.

RESULTS

Caregiver priority challenges included managing dementia behaviors, understanding disease expectations, and performing activity of daily living care. Improvements were observed across the three categories in both groups; however, not all changes were statistically significant. No significant differences were identified between groups.

CONCLUSION

Caregivers in the FamTechCare group reported benefit across all priority challenges including managing dementia behaviors, understanding disease expectations, and performing activity of daily living care.

CLINICAL IMPLICATIONS

Innovative technology provides new opportunities to support family caregivers in dementia home care. Video-recording can be used to enhance support for family caregivers facing care challenges.

Pharmacotherapy of Behavioral and Psychological Symptoms of Dementia: State of the Art and Future Progress

The core symptoms of different dementia subtypes are the behavioral and psychological symptoms of dementia (BPSD) and its neuropsychiatric symptoms (NPS). BPSD symptoms may occur at any stage in the case of dementia due to Alzheimer's disease (AD), whereas they tend to occur early on in the case of its behavioral variant frontotemporal dementia or dementia with Lewy bodies and are essential for diagnosis. BPSD treatment consists of non-pharmacological as well as pharmacological interventions, with non-pharmacological interactions being suggested as first-line treatment. Agitation, psychotic features, apathy, depression, and anxiety may not respond to acetylcholinesterase inhibitors or memantine in AD cases; therefore, antipsychotics, antidepressants, sedative drugs or anxiolytics, and antiepileptic drugs are typically prescribed. However, such management of BPSD can be complicated by hypersensitivity to antipsychotic drugs, as observed in DLB, and a lack of effective pro-cognitive treatment in the case of frontotemporal dementia. The present paper reviews current knowledge of the management of BPSD and its limitations and discusses on-going clinical trials and future therapeutic options.

Using a therapeutic companion robot for dementia symptoms in long-term care: reflections from a cluster-RCT

OBJECTIVES

We undertook a cluster-randomised controlled trial exploring the effect of a therapeutic companion robot (PARO) compared to a look-alike plush toy and usual care on dementia symptoms of long-term care residents. Complementing the reported quantitative outcomes , this paper provides critical reflection and commentary on individual participant responses to PARO, observed through video recordings , with a view to informing clinical practice and research.

METHOD

A descriptive, qualitative design with five participants selected from the PARO intervention arm of the trial. The trial is registered with the Australian New Zealand Clinical Trials Registry (ACTRN12614000508673).

RESULTS

The five participants and their responses to PARO are presented in terms of three issues: i.) Different pre-intervention clinical presentations and different responses; ii.) Same individual, different response - the need for continual assessment and review; and iii.) The ethics of giving and retrieving PARO. Implications for clinical practice and future research are discussed in relation to each issue.

CONCLUSION

The findings suggest that one approach does not fit all, and that there is considerable variation in responses to PARO. A number of recommendations are discussed to aid the delivery of psychosocial interventions with PARO in practice, as well as to guide future research.

Impact of Environmental Modifications to Enhance Day-Night Orientation on Behavior of Nursing Home Residents With Dementia

OBJECTIVES

To determine whether environmental rearrangements of the long-term care nursing home can affect disruptive behavioral and psychological symptoms of dementia (BPSD) in residents with dementia.

DESIGN

Prospective 6-month study.

SETTING

The study was conducted before (phase 1) and after (phase 2) environmental rearrangements [skylike ceiling tiles in part of the shared premises, progressive decrease of the illuminance at night together with soothing streaming music, reinforcement of the illuminance during the day, walls painted in light beige, oversized clocks in corridors, and night team clothes color (dark blue) different from that of the day team (sky blue)].

PARTICIPANTS

All of the patients (n = 19) of the protected unit were included in the study. They were aged 65 years or older and had an estimated life expectancy above 3 months.

MEASURES

Number and duration of disruptive BPSD were systematically collected and analyzed over 24 hours or during late hours (6:00-12:00 pm) during each 3-month period.

RESULTS

There was no significant change in the patients' dependency, risk of fall, cognitive or depression indexes, or treatment between phase 1 and 2. Agitation/aggression and screaming were observed mainly outside the late hours as opposed to wandering episodes that were noticed essentially within the late hours. The number of patients showing wandering was significantly lower over 24 hours during phase 2. The number of agitation/physical aggression, wandering, and screaming and the mean duration of wandering episodes were significantly (P = .039, .002, .025, and .026 respectively) decreased over 24 hours following environmental rearrangements. Similarly, a significant reduction in the number and mean duration of wandering was noticed during the late hours (P = .031 and .007, respectively).

CONCLUSIONS

Our study demonstrates that BPSD prevalence can be reduced following plain environmental rearrangements aimed at improving spatial and temporal orientation.

[Predictors of Behavioral and Psychological Symptoms of Dementia: Based on the Model of Multi-Dimensional Behavior]

PURPOSE

The purpose of this study was to identify factors predicting behavioral and psychological symptoms of dementia (BPSD) in persons with dementia. Factors including the patient, caregiver, and environment based on the multi-dimensional behavioral model were tested.

METHODS

The subjects of the study were 139 pairs of persons with dementia and their caregivers selected from four geriatric long-term care facilities located in S city, G province, Korea. Data analysis included descriptive statistics, inverse normal transformations, Pearson correlation coefficients, Spearman's correlation coefficients and hierarchical multiple regression with the SPSS Statistics 22.0 for Windows program.

RESULTS

Mean score for BPSD was 40.16. Depression (β=.42, p<.001), exposure to noise in the evening noise (β=-.20, p=.014), and gender (β=.17, p=.042) were factors predicting BPSD in long-term care facilities, which explained 25.2% of the variance in the model.

CONCLUSION

To decrease BPSD in persons with dementia, integrated nursing interventions should consider factors of the patient, caregiver, and environment.

Detection, diagnosis, and treatment of Alzheimer's disease dementia stratified by severity as reported by caregivers in Japan

BACKGROUND

Dementia of Alzheimer's disease (AD) imposes burdens on patients, caregivers, and society. This cross-sectional study examined caregiver-reported history of disease onset and AD dementia to inform efforts promoting early disease detection and diagnosis.

METHODS

An online survey collected self-reported cross-sectional data - demographic characteristics, diagnosis, treatment experiences, and other information on disease detection, diagnosis, and treatment - from caregivers of patients with AD dementia. These characteristics were examined as a function of AD dementia severity.

RESULTS

Three hundred patients with AD dementia were trichotomized by long-term care insurance levels reported by caregivers: 12.3% (n=37) as low severity, 63.7% (n=191) as medium severity, and 24.0% (n=72) as high severity. The Short-Memory Questionnaire and patient dependency scores both varied significantly across severity groups. AD dementia symptoms were most frequently first detected by a caregiver (58.7%) or the patient's family (45.7%). However, in 13.7% of cases, symptoms were detected by a health care provider during a routine visit. Memory problems were the most frequent first symptoms (77.3%), followed by repetition (55.7%). Patients (73.7%) were taking symptomatic treatment such as acetylcholinesterase inhibitors or memantine. High-severity patients were older, had been diagnosed with AD dementia for a longer time, had more frequent reports of memory problems as the first symptoms detected, and required more hours of care per day, compared with low-severity patients.

CONCLUSION

Caregivers and families play an integral role in the identification of AD dementia patients, with memory problems being common first symptoms noticed by caregivers that led to a diagnosis of AD dementia. These results provide novel insight into the detection, diagnosis, and treatment of AD dementia in Japan and how these factors differ across the spectrum of disease severity.

Use of Antipsychotic Drugs by Elderly Primary Care Patients and the Effects of Medication Reviews: A Cross-Sectional Study in Sweden

BACKGROUND

Antipsychotics form a class of drugs that should be used with caution among elderly people because of a high risk of adverse events. Despite the risks and modest effects, their use is estimated to be high, especially in nursing homes.

OBJECTIVE

The aim was to explore the effects of medication reviews on antipsychotic drug use for elderly primary care patients and describe the extent of, and reasons for, the prescription of antipsychotics.

METHODS

In this cross-sectional study in primary care in Skåne, Sweden, patients aged ≥75 years living in nursing homes or in their own homes with home care were included. The effects of medication reviews were documented, as were the use of antipsychotics and the differences in characteristics between patients receiving or not receiving antipsychotics.

RESULTS

A total of 1683 patients aged 87.6 (±5.7) years were included in the analysis. Medication reviews reduced the use of antipsychotics by 23% (p < 0.001) in this study. Of the 206 patients using antipsychotics, 43% (n = 93) had an approved indication, while for 15% (n = 32) the indication was not given. Antipsychotic drug use was more common with increasing number of drugs (p = 0.001), and in nursing home residents (p < 0.01). It was also more frequent in patients with cognitive impairment, depressive symptoms or sleeping problems.

CONCLUSION

The use of antipsychotic drugs is high in elderly patients in nursing homes. They are often given for indications that are not officially approved or are poorly documented. Medication reviews appear to offer one useful strategy for reducing excessive use of these drugs.
