Nonpharmacologic management of behavioral symptoms in dementia

Psychosis associated with dementia: evaluation and management

Dementia is one of the most common neurodegenerative disorders in the world, and 34-63 % of individuals with dementia have psychotic symptoms. Neurobiological correlates of dementia with psychosis include significantly increased densities of senile plaques and neurofibrillary tangles and higher D3 receptor density. Limitations of proposed diagnostic criteria include a lack of specificity for psychotic symptoms in individuals with dementia, a lack of consistent differentiation between symptoms, late recognition, and not accounting for comorbid depression or agitation that may be the primary symptom, which makes diagnosis challenging. This review aims to provide clinicians, researchers, and policymakers with a comprehensive evaluation of psychosis in dementia, covering its epidemiology, neurobiology, diagnosis, and treatment strategies. We review both psychosocial and pharmacological interventions for dementia-related psychosis. Psychosocial treatments such as meaningful communication between persons with dementia and their caregivers, simplifying the living environment, and optimizing tasks can help reduce the adverse impact of psychosis. Evidence from meta-analyses indicates modest efficacy for cholinesterase inhibitors, antidepressants, and antipsychotics for psychosis in dementia. The use of antipsychotic medications is limited by increased risks for serious adverse effects including cerebrovascular events and death. Emerging therapies such as xanomeline-trospium present promising avenues for treatment. By synthesizing current evidence and clinical guidelines, this review provides a framework for improving diagnosis and treatment of psychosis in dementia, helping clinicians and researchers refine patient care strategies while informing future research directions.

The disease burden, risk factors and future predictions of Alzheimer's disease and other types of dementia in Asia from 1990 to 2021

BACKGROUND

There is a lack of analysis and prediction of the disease burden of Alzheimer's disease and other dementias (ADOD) in Asia.

OBJECTIVES

This study aims to explore the impact of ADOD on the Asian region during the period from 1990 to 2021.

DESIGN

Data on ADOD in Asia from 1990 to 2021 were collected from the Global Burden of Disease (GBD) Study 2021. We analyzed the number and age-standardized rates (ASRs) of incidence, prevalence, mortality, and disability-adjusted life-years (DALYs) of ADOD from 1990 to 2021. Joinpoint regression analysis was performed, and the average annual percent changes (AAPCs) were calculated to evaluate the trends during this period. Subsequently, an auto - regressive integrated moving average (ARIMA) prediction model analysis was conducted to assess the trends in the next 30 years, aiming to report the epidemiology and disease burden of ADOD in Asia.

RESULTS

According to the analysis of the GBD database in 2021, the deaths, DALYs, incidence, and prevalence of ADOD increased by 297.34 %, 249.54 %, 244.73 %, and 250.44 % in Asia from 1990 to 2021. The ASRs of incidence, prevalence, death, and DALYs in both males and females, which consistently increased over the study period, showed that the ASRs of all females were consistently higher than those of males in Asia from 1990 to 2021. During the period from 1990 to 2021, Qatar and the United Arab Emirates witnessed the greatest changes in the number of DALYs, incidence, and prevalence. Afghanistan and China had the highest age-standardized mortality rate (ASMR) in 2021. It is worth noting that high fasting blood glucose is the top risk factor for the onset of ADOD. Females are more susceptible to the risk factor of high body-mass index (BMI), while males are more likely to be affected by smoking. According to the analysis of the ARIMA prediction model, the disease burden of ADOD in Asia will continue to show an upward trend in the next 30 years.

CONCLUSIONS

We should pay attention to the issue of population aging, attach importance to the intervention measures targeting the risk factors of ADOD, and formulate action plans to address the rising incidence of ADOD.

The effect of cognitive stimulation therapy (CST) on apathy, loneliness, anxiety and activities of daily living in older people with Alzheimer's disease: randomized control study

OBJECTIVES

This study was conducted to determine the effect of Cognitive Stimulation Therapy (CST) on apathy, loneliness, anxiety, and activities of daily living of individuals with Alzheimer's disease.

METHOD

The study was conducted in a daily care center between January 2023 and January 2024 in a randomized control study. A total of 52 people, 26 intervention and 26 control groups, were enrolled in the study and formed the sample of the study. Demographic Information Form, Apathy Evaluation Scale (AES-C), Geriatric Anxiety Scale (GAS), UCLA Loneliness Scale Short Form (UCLA-SF), and Functional Impairment in Dementia Scale (DAD) were used in the study.

RESULTS

After the intervention, it was found that the intervention group's levels of apathy, loneliness and anxiety were significantly reduced compared to the control group. In the intra-group comparisons, it was found that there was a significant difference between the pre-test and post-test scores of the AES-C, UCLA-SF, GAS of the individuals in the intervention group after the application of CST, and between the pre-test and pre-test scores of the DAD (p < 0.05).

CONCLUSION

CST was found to be effective in reducing apathy, loneliness and anxiety levels and increasing daily living activities in older people with Alzheimer's disease.

Telehealth coaching in older adults, behavior change, and impacts of the COVID-19 pandemic: analyses from The Brain Health Champion Study

Introduction

When COVID-19 containment strategies were imposed in March 2020, we became interested in how these restrictions might interfere with brain-healthy behaviors of older adults who were either actively participating in or who had recently completed our telehealth behavior change intervention. Telehealth interventions have emerged as important tools for supporting brain health behaviors remotely, particularly among older adults. The objective of the current study was to assess how older adults with and without cognitive impairment were affected by COVID-19 restrictions and whether they were affected differently based on their active participation or recent completion of our Brain Health Champion (BHC) study and their cognitive status.

Methods

BHC study 1.0 and 2.0 participants and their study partners were emailed in April and May of 2020 a link to five electronic surveys to collect qualitative and quantitative data on various health factors, including self-reports of pre-pandemic and current brain health behaviors (e.g., physical activity, Mediterranean diet adherence, social engagement, and cognitive stimulation), anxiety, sleep, and depression. The fifth survey was distributed to collect study feedback.

Results

Ten out of 11 participants from Study 2.0 and 15 out of 30 participants from Study 1.0 completed the surveys. Results demonstrated that early pandemic restrictions negatively impacted all participants in physical activity (p < .01) and social interactions (p < .001), with no impact on cognitive activities (p = .479) and dietary intake (p = .814). A significant difference was found between Study 1.0 and 2.0 participants (p < .001) in self-reported changes in level of cognitive activity. Study 1.0 participants indicated a decrease in cognitive activities since the start of COVID-19 restrictions, whereas those in Study 2.0 reported an increase in cognitive activities.

Discussion

Our findings suggest that pandemic restrictions significantly impacted activities typically done outside the home (social and physical activity), while those feasibly achieved at home were less affected (Mediterranean diet adherence and cognitive activity). Additionally, the intervention augmented by digital health components likely exerted some protective effects against the impact of COVID-19 containment strategies. Digitally-facilitated research and clinical telehealth programs are well-positioned to offer some protection to vulnerable individuals from disruptive events that could impede adoption or maintenance of healthy lifestyle changes.

Neuropsychiatric Symptoms and Psychotropic Medication Use Following SARS-Cov-2 Infection Among Elderly Residents in Long-Term Care Facilities

Background

SARS-CoV-2 infection can lead to persistent post-acute neuropsychiatric symptoms. Older adults with multimorbidity may be at increased risk of post-acute symptoms after COVID-19. The goals of the present study were to assess the associations of SARS-CoV-2 infection with neuropsychiatric symptoms and psychotropic medication prescription among older adults living in long-term care facilities.

Methods

Nursing home residents (n=111) participated in this three-month longitudinal study. Nurse ratings of neuropsychiatric symptoms were conducted at baseline and at the three-month follow-up. SARS-CoV-2 infection status and psychotropic medication prescription were extracted from a medical chart review.

Results

About 73.9% of participants were infected with SARS-CoV-2 on average 480.49 (SD= 228) days before study enrollment. There were no significant changes in neuropsychiatric symptoms during the study follow-up period. Participants with a SARS-CoV-2 infection had more agitation compared to those who were never infected. However, this effect disappeared after adjusting for age, sex, history of psychiatric disorder, neurocognitive status, and multimorbidity. Participants with SARS-CoV-2 had a higher number of psychotropic medication prescription. This effect was driven by increased use of antidepressants and antipsychotic medications.

Conclusion

Both acute and short-term neuropsychiatric symptoms associated with COVID-19 may contribute to long-term psychoactive polypharmacy among older adults living in long-term facilities.

"I Must Be the One to Change; He's Doing the Best He Can": Care Partner Evaluation Results from a Four-Part, In-Person, Dementia Community Education Program

We created a comprehensive, four-part, in-person, interactive community education series to teach informal, unpaid care partners of persons living with dementia (PLWD) how to support their PLWD, negotiate common day-to-day challenges, and navigate predictable situations that arise as the disease progresses over time. The purpose of this qualitative study was to explore the series impact on participant knowledge, care practices, and perceptions of caregiving. Inspired by the U.S. Medicare Cognitive Assessment and Care Plan Service visit and the 4Ms of the Age-Friendly Health Systems Framework, our curriculum focused on (1) expanding knowledge about the disease and disease progression, (2) developing skills to better connect and work with PLWD, (3) self-care for care partners, and (4) sharing resources to support future planning. The program was delivered in three communities in Central Pennsylvania (one rural, one small, and one medium metropolitan) and was attended by 146 individuals. Both session and final qualitative evaluation data were assessed using thematic analysis and five major categories emerged: lessons learned, activating new knowledge, impact and changes, assuming responsibility is challenging, and I need more help. Ongoing education, emotional support, and access to quality assistance for long-term planning are all needed and require sustained support.

Cost-Effectiveness of the Tailored Activity Programme for Person With Dementia-Caregiver Dyads: A Markov Model

OBJECTIVES

The Tailored Activity Programme (TAP) is a home-based programme with compelling outcomes for reducing behavioural and psychological symptoms of dementia and functional decline. We conducted a cost-utility analysis of TAP compared to usual care, for the person with dementia and their caregiver.

METHODS

We developed a Markov Model, from the healthcare sector perspective. Using parameters from the dementia care literature. Base-case and probabilistic sensitivity analyses were applied to handle uncertainty.

RESULTS

Given the growing need for cost-effective dementia care, understanding the cost-effectiveness of TAP is crucial for health service design and its implementation into healthcare settings. Our study shows that TAP is cost-effective for both males and females with dementia and their caregivers. The most favourable cost-effectiveness acceptability curves were found in men and women with dementia, aged 50 to 70, with lower costs and higher QALYs compared to those over 80. The probability of TAP being cost-effective rises with public higher willingness-to-pay thresholds, especially for people with dementia in the age group of 50-70.

CONCLUSIONS

These findings indicate TAP is highly cost-effective for individuals living with dementia compared to usual home care, which provides evidence for policy makers towards their decisions on resource allocation and for implementing TAP in Australia.

Ecopsychosocial strategies for the self-exploration of professional family caregivers to manage the behavioural and psychological symptoms of Alzheimer patients in Iran: a qualitative study

OBJECTIVE

The aim of the present study was to explore the experiences and viewpoints of professional family caregivers in the management of behavioural and psychological symptoms of dementia (BPSDs) to identify the ecopsychosocial strategies applied by them.

DESIGN

Qualitative study.

SETTING

Kerman, Iran.

PARTICIPANTS

Stories were collected from 40 professional family caregivers of dementia patients.

MEASUREMENT

The guidelines of the National Consensus Project (NCP) of the USA served as the conceptual framework for the deductive thematic analysis of our qualitative data. A schematic of the entire process was performed in five steps.

RESULTS

30 stories relevant to the aim of this study were included in the analysis from April to June 2021. A majority of the stories were written by female caregivers. We identified 19 ecopsychosocial interventions, which covered the NCP dimensions except 'Care of the patient nearing the end of life'. More than half of these interventions were classified into psychological/psychiatric and physical aspects of care (57.8%). In addition to the care/support provided by special care units or home care, some caregivers believe that support from the government, various care organisations, social media and even other family members/friends is necessary to better manage BPSDs.

CONCLUSION

Despite limitations, such as having a small sample size and analysing only one story from each caregiver, our results indicate that dementia caregivers need more educational and cultural support in their ecopsychosocial strategies. Government involvement would yield more positive outcomes in managing BPSDs.

Challenges and Opportunities in Implementing a Multicomponent Dementia Caregiver Program in a Complex Healthcare System

The Tailored Activity Program (TAP), an intervention for people living with dementia (PLWD) and their caregivers, has been shown to reduce behavioral symptoms for PLWD and caregiver burden. While TAP is proven as an evidence-based practice (EBP), it has yet to be implemented at scale. The Department of Veterans Affairs (VA) has prioritized the Age-Friendly Health System (AFHS) initiative, providing an opportunity to test implementation of TAP in a complex healthcare system. We conducted semi-structured pre-implementation interviews with leaders and clinicians at 6 VA Medical Centers (VAMCs) to engage key implementation partners and understand their unique implementation contexts. We utilized team-based rapid qualitative analysis to identify themes related to implementation determinants. We interviewed 65 unique informants in 58 interviews (5 VAMC leaders, 36 department leaders, and 17 frontline clinical staff). Informants identified 4 key factors critical to consider prior to implementing TAP: (1) alignment with organizational priorities; (2) perceived value and fit with existing clinical workflows; (3) competition with existing organizational and clinical priorities; and (4) considerations about the effect of caregiver burden on participation. We identified key factors to consider for successful implementation of a multicomponent intervention for PLWD and their caregivers within a complex healthcare system. As the AFHS initiative expands, there is a growing need for EBPs focused on the care of PLWD and their caregivers. These factors can guide clinicians, leaders, and implementation scientists in planning for implementation and sustainment of EBPs to bolster AFHS initiatives.Trial RegistrationRegistered 05 May 2021, at ISRCTN #60,657,985.Reporting GuidelinesThe COnsolidated criteria for REporting Qualitative research (COREQ) checklist was used to ensure proper standards for reporting qualitative studies (see attached).

A Nursing Home Clinician Survey to Explain Gabapentinoid Increases

OBJECTIVES

Survey nursing home (NH) clinicians about the indications for NH gabapentinoid use, the factors driving increased prescribing, and their experiences with gabapentinoid deprescribing.

DESIGN

Online clinician survey.

SETTING AND PARTICIPANTS

NH clinicians prescribing gabapentinoids in US NHs.

METHODS

An anonymous survey of NH prescribers was conducted using SurveyMonkey from March 15 to July 1, 2024. Recruitment employed crowdsourcing, targeting the membership of NH clinician organizations. A multidisciplinary team developed the instrument. Content focused on the magnitude of gabapentinoid prescribing for different, previously identified, indications, as well as clinician deprescribing experiences and perspectives.

RESULTS

Sixty-two self-identified NH prescribers participated: 76% white, 55% female, 77% physicians. One-third had geriatric training certifications. Most NH gabapentinoids were started in other care settings by non-NH clinicians. Gabapentinoid prescribing initiated in NHs was principally off-label for pain syndromes. Although prescribing solely for psycho-behavioral symptoms was rare, most clinicians reported that gabapentinoids have some utility in treating these symptoms and consequently may be preferred over alternative analgesics when psycho-behavioral symptoms coexist with pain. Gabapentinoid deprescribing occurs infrequently and is deprioritized relative to opioid reduction efforts. Most clinicians acknowledged potential gabapentinoid side effects; however, severe harms were rarely observed, and half agreed that gabapentinoids are generally safe and well-tolerated. Seventy-nine percent perceive gabapentinoids as safer and better tolerated than opioids, 57% than benzodiazepines, and 40% than antipsychotics.

CONCLUSIONS AND IMPLICATIONS

An opportunity exists to increase NH safety by prioritizing gabapentinoid gradual dose reduction requirements. Because so many prescriptions originate outside NHs, any reduction effort should emphasize deprescribing across all care settings. Clinicians' perceptions of gabapentinoids as reasonable but unmonitored alternatives to opioids and psychotropics contribute to their increased use. Safety and efficacy data supporting such prescribing for nonapproved indications in NHs is lacking. Existing NH psychotropic reporting and reduction mandates should include gabapentinoids regardless of indication.

Impacts of adapted dance on mood and physical function among persons living with Alzheimer's disease

BACKGROUND

Most individuals living with Alzheimer's disease and related dementias (ADRD) experience one or more neuropsychiatric symptoms, such as agitation which negatively impacts their quality of life. Adapted dance integrates recorded music and movement that is appropriate for people with cognitive limitations. Adapted dance may be an enjoyable activity for persons living with ADRD and may provide psychological and physical benefits.

OBJECTIVE

The purpose of this pilot study was to assess the feasibility of an adapted dance intervention with persons with ADRD and the impacts of 12 weeks of adapted dancing on agitation, balance, gait, lower extremity strength, and caregiver burden.

METHODS

This study used an experimental design with repeated measures. Participants with ADRD were randomly assigned to a usual care or adapted line dance group that met 60 min twice a week. At pre-test, 4-, 8-, and 12 weeks of intervention, measures were collected for agitation, balance, gait, lower extremity strength, and caregiver burden.

RESULTS

The sample consisted of 4 males and 12 females (n = 16) with ADRD whose age ranged from 69-97 years. Twelve weeks of adapted line dance was found acceptable by ADRD participants. Participants attended ≥90% of dance sessions and did not experience loss of balance or fall. ADRD participants danced an average of 70 min per week. Both groups had improvements in agitation from baseline to 12 weeks.

CONCLUSIONS

Twelve weeks of adapted dance was shown to be feasible and enjoyable for persons living with ADRD. Clinicians should consider adapted dance as part of an exercise prescription.

Implementing New Dementia Care Models in Practice

ABSTRACT

Care for patients with Alzheimer disease and related neurodegenerative causes of dementia is in the midst of a transformation. Recent advancements in diagnostics and therapeutics reflect a rapidly evolving knowledge base and represent positive steps for patients and clinicians facing these progressive diseases; however, the complexities of emerging biomarkers and treatment options present challenges that will require systematic adaptations to routine care to facilitate effective incorporation of these options. This article reviews ongoing updates in the assessment and management of neurodegenerative causes of dementia, focusing on practical models for innovation that practices and health care systems can use to implement these new tools. In particular, sustainable adaptation in the field will benefit from a comprehensive approach implemented at local levels, including (1) education of clinicians and communities to refine perceptions about dementia care, (2) multifaceted stakeholder engagement to optimize infrastructure and workflows to the new era, and (3) investments in personnel to address existing and exacerbated gaps.

Antipsychotic drugs for anorexia nervosa

OBJECTIVES

This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To assess the effects of antipsychotic drugs (both first- and second-generation antipsychotics) compared to placebo on body weight gain, psychological symptoms, acceptability, and adverse events for people with anorexia nervosa.

Symptom-specific non-pharmacological interventions for behavioral and psychological symptoms of dementia: An umbrella review

BACKGROUND

Non-pharmacological interventions are considered the first-line treatment for managing the behavioral and psychological symptoms of dementia. Given the heterogeneous characteristics of these symptoms, which vary for each individual and tend to fluctuate, a symptom-specific approach is necessary for providing individualized non-pharmacological interventions for people with dementia. However, clear guidelines regarding the appropriate types of interventions for individual symptoms or clusters of behavioral and psychological symptoms of dementia are lacking.

OBJECTIVES

The aim of this umbrella review was to summarize the current evidence on non-pharmacological interventions for behavioral and psychological symptoms of dementia and provide guidance for determining the appropriate types of interventions for each behavioral and psychological symptom of dementia.

DESIGN

An umbrella review of systematic reviews and/or meta-analyses.

METHODS

The Cochrane methodology for umbrella reviews was employed for this review, and the review protocol was registered. PubMed, CINAHL, Embase, PsycINFO, and Cochrane databases were searched for relevant reviews using the 'population, intervention, control, and outcomes' formulation. Two reviewers independently screened the extracted articles for eligibility. The quality of each selected review was independently assessed by the two reviewers using A Measurement Tool to Assess Systematic Reviews 2. The results were narratively synthesized and categorized according to each symptom.

RESULTS

Thirty-five systematic reviews, 71 % of which were also meta-analyses, were included in this review. The methodologies employed in the included reviews were significantly heterogeneous. The qualities of the reviews ranged from low to moderate. Diverse types of non-pharmacological interventions were identified in the reviews, with music therapy being the most frequently discussed. Among the various symptoms, depression was most frequently addressed, followed by overall symptoms, agitation, anxiety, sleep problems, and apathy. Music therapy was found to be effective for improving both overall and specific symptoms, including depression and anxiety. Notably, relatively weak evidence supports the effectiveness of exercise in addressing each symptom. Aromatherapy could be considered for agitation, whereas reminiscence may be effective in managing overall and specific symptoms, such as depression.

CONCLUSIONS

The results showed that the evidence of symptom-specific effectiveness of non-pharmacological interventions varied across the different behavioral and psychological symptoms of dementia, highlighting the need for a symptom-specific approach in future research. Furthermore, future research is needed to facilitate the development of symptom-specific guidelines that can enhance the quality of individualized dementia care.

A Personalized Music Intervention in Nursing Home Residents Living With Dementia: Findings From a Randomized Study

Utilizing a randomized control design, this mixed method study aimed to assess the impact of a personalized music intervention on mood, agitation level, and psychotropic drug use in individuals with moderate to advanced dementia residing in long-term care facilities. The sample comprised of 261 participants, with 148 in the intervention group and 113 in the control group. Data were collected from three sources: quantitative data from the Minimum Data Set and the Cohen-Mansfield Agitation Inventory, observational data of music-listening sessions, and an administrator survey regarding the lead staff person's perceptions of the intervention. Findings, based on Mixed Effect Models and content analyses, revealed positive impacts of the personalized music intervention on residents living with dementia. This low-cost, easily implementable intervention, requiring no special licensure for administration, can significantly enhance the quality of life for nursing facility residents.

Understanding Long-Stay Gabapentin Use Increases: A National Nursing Home Clinician Survey on Prescribing Intent

OBJECTIVES

Explore the indications for long-stay gabapentin use and elucidate the factors spurring the rapid increase in gabapentin prescribing in nursing homes (NHs).

METHODS

National cross-sectional survey of NH prescribers distributed anonymously using SurveyMonkey. Sampling for convenience was obtained through crowdsourcing, leveraging collaborations with NH clinician organizations. Developed by a multidisciplinary team, pilot data/existing literature informed survey content.

RESULTS

A total of 131 surveys completed. Participants: 71% white, 52% female, 71% physicians. Off-label gabapentin prescribing was ubiquitous. Nearly every clinician used gabapentin for neuropathic pain, most for any form of pain. Many clinicians also prescribe gabapentin to moderate psychiatric symptoms and behaviors. Clinicians' prescribing was influenced by opioid, antipsychotic, and anxiolytic reduction policies because gabapentin was perceived as an unmonitored and safer alternative.

CONCLUSIONS

Off-label gabapentin increases are closely linked to opioid reduction efforts as more NH clinicians utilize gabapentin as an unmonitored opioid alternative. Our results highlight, however, the less recognized significance of long-stay prescribing for psychiatric symptoms and the similar contribution of psychotropic reduction initiatives, a phenomenon warranting further scrutiny.

CLINICAL IMPLICATIONS

Clinicians perceive gabapentin as safer than the drugs it is replacing. Whether this is true remains unclear; the individual- and population-level risks of increased gabapentin use are largely unknown.

Brexpiprazole for Agitation Associated With Dementia Due to Alzheimer's Disease

Alzheimer's disease (AD) is a prevalent neurodegenerative disease characterized by progressive cognitive and functional decline. Nearly all patients with AD develop neuropsychiatric symptoms (NPSs). Agitation is one of the most distressing and challenging NPS. Brexpiprazole is an oral antipsychotic and is the first approved pharmacologic agent in the United States for the treatment of agitation associated with dementia due to AD. Its effect is thought to be from its partial serotonin 5-HT1A and dopamine D2 receptor agonist activity and serotonin 5-HT2A receptor antagonism. Brexpiprazole is a maintenance medication, and it should not be used "as needed" or as a "PRN" treatment for breakthrough agitation. Brexpiprazole is a major substrate of CYP2D6 and CYP3A4. Dose adjustments may be required for drug interactions or impaired renal or hepatic function. Clinical trials found brexpiprazole 2 to 3 mg/d demonstrated significant improvements in agitation, with brexpiprazole showing an approximate 5-point greater reduction on change in the Cohen-Mansfield Agitation Inventory total score at week 12 from baseline compared with placebo. Brexpiprazole is generally well tolerated and safe, and common adverse reactions when used for this indication include dizziness, headaches, insomnia, nasopharyngitis, somnolence, and urinary tract infections. Like other antipsychotics used for agitation in AD, brexpiprazole is associated with higher mortality rates compared with placebo. In a long-term care setting, there are several considerations for its use. Benefits include an oral agent that is well tolerated and clinical data showing statistically significant effects on agitation. However, brexpiprazole has not been studied in head-to-head clinical trials against other antipsychotics, and there are differing opinions if the agitation score reductions translate to a clinically meaningful difference. The approval of brexpiprazole signals favorably for upcoming agents for this indication, including escitalopram and dextromethorphan-bupropion. Both escitalopram and dextromethorphan-bupropion are currently undergoing clinical trials.

Crosswalk Algorithms for Cognitive and Functional Outcomes Among 2013-2018 Medicare Beneficiaries With Dementia

OBJECTIVE

Before 2019, the Minimum Data Set (MDS) and Outcome and Assessment Information Set (OASIS) had incongruent response categories for rating cognitive impairment and activities of daily living (ADLs), hindering direct comparisons between nursing facilities and home health. We devised rule-based algorithms to compare cognitive impairment and ADL limitations between these 2 care settings among people with Alzheimer's disease and Alzheimer's disease-related dementias (ADRD).

DESIGN

A retrospective cohort study.

SETTING AND PARTICIPANTS

Included fee-for-service Medicare beneficiaries (2013-2018) transitioning from nursing facilities to home health, with 1-year of continuous enrollment, aged ≥65 years, diagnosed ADRD, and with complete MDS discharge and OASIS admission assessments (N = 398,496).

METHODS

We identified target phenotypes using the Cognitive Function Scale (CFS) and ADL items from the MDS discharge assessment as reference standards. We compared 6 OASIS-based algorithms for cognitive impairment and 1 for each ADL limitation by estimating sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV).

RESULTS

The average age was 83.5 (SD = 7.5) years and 82.3% transitioned from nursing to home health within 3 days. In the MDS discharge assessment, 42.2% had moderate-to-severe cognitive impairment. ADL limitations ranged from 71.4% for feeding to 97.8% for bathing. Compared with the moderate-to-severe cognitive impairment (CFS ≥3) on the MDS, the OASIS cognitive assessment indicating "considerable assistance to total dependence in routine situations" had 24% sensitivity, 94% specificity, 75% PPV, and 63% NPV. The ADL limitation algorithms exhibited high sensitivities (>96%) and PPVs (>94%) except for feeding (Sensitivity: 82%; PPV: 74%). Despite the short time frame between the 2 assessments, the OASIS admission assessment showed a higher prevalence of ADL limitations than the MDS discharge assessment.

CONCLUSIONS AND IMPLICATIONS

We highlighted differences in patient function between post-acute care settings. Our algorithms can help researchers, clinicians, and policymakers standardize patient-centered outcomes for comparative effectiveness research or quality initiatives.

Experiences managing behavioral symptoms among Latino caregivers of Latino older adults with dementia and memory problems: a qualitative study

BACKGROUND

Latinos are more likely than non-Latino Whites to develop dementia and be prescribed antipsychotics for dementia-related behavioral symptoms. Antipsychotics have significant risks yet are often overprescribed. Our understanding of how Latino caregivers of Latino older adults living with dementia perceive and address behavioral issues is limited, impeding our ability to address the root causes of antipsychotic overprescribing.

METHODS

We interviewed Latino older adults' caregivers and community-based organization workers serving older adults with cognitive impairment (key informants), focusing on the management of behavioral symptoms and experiences with health services.

RESULTS

We interviewed 8 caregivers and 2 key informants. Caregivers were the spouses, children, or grandchildren of the older adult living with cognitive impairment; their ages ranged from 30 to 95. We identified three categories of how caregivers learned about, managed, and coped with behavioral symptoms: caregivers often faced shortcomings with dementia care in the medical system, receiving limited guidance and support; caregivers found community organizations and senior day centers to be lifelines, as they received relevant, timely advice and support, caregivers often devised their own creative strategies to manage behavioral symptoms.

CONCLUSION

In-depth interviews suggest that the healthcare system is failing to provide support for behavioral symptoms from dementia; caregivers of Latino older adults rely on community organizations instead.

A model for identifying potentially inappropriate medication used in older people with dementia: a machine learning study

BACKGROUND

Older adults with dementia often face the risk of potentially inappropriate medication (PIM) use. The quality of PIM evaluation is hindered by researchers' unfamiliarity with evaluation criteria for inappropriate drug use. While traditional machine learning algorithms can enhance evaluation quality, they struggle with the multilabel nature of prescription data.

AIM

This study aimed to combine six machine learning algorithms and three multilabel classification models to identify correlations in prescription information and develop an optimal model to identify PIMs in older adults with dementia.

METHOD

This study was conducted from January 1, 2020, to December 31, 2020. We used cluster sampling to obtain prescription data from patients 65 years and older with dementia. We assessed PIMs using the 2019 Beers criteria, the most authoritative and widely recognized standard for PIM detection. Our modeling process used three problem transformation methods (binary relevance, label powerset, and classifier chain) and six classification algorithms.

RESULTS

We identified 18,338 older dementia patients and 36 PIMs types. The classifier chain + categorical boosting (CatBoost) model demonstrated superior performance, with the highest accuracy (97.93%), precision (95.39%), recall (94.07%), F1 score (95.69%), and subset accuracy values (97.41%), along with the lowest Hamming loss value (0.0011) and an acceptable duration of the operation (371s).

CONCLUSION

This research introduces a pioneering CC + CatBoost warning model for PIMs in older dementia patients, utilizing machine-learning techniques. This model enables a quick and precise identification of PIMs, simplifying the manual evaluation process.

Technology-based group exercise interventions for people living with dementia or mild cognitive impairment: A scoping review

Older people living with dementia or mild cognitive impairment (MCI) are more vulnerable to experiencing social isolation and loneliness due to their cognitive and physical impairments. Increasingly integrating technology into group exercises contributed to the improved resilience and well-being of older adults living with dementia and MCI. The purpose of this scoping review was to identify the various types, feasibility, outcome measures, and impacts of technology-based group exercise interventions for people with dementia or MCI. We utilized the Joanna Briggs Institute approach, a three-step process. A comprehensive literature search on five databases-CINAHL, MEDLINE, Embase, Web of Science, and PsycInfo-until January 2024 yielded 1,585 publications; the final review included 14 publications that recruited a total of 379 participants, with mean age of 69 (SD = 4.21) years to 87.07 (SD = 3.92) years. Analysis of data showed three types of technology-based group exercise interventions for people with dementia or MCI: (a) exergames, (b) virtual cycling or kayak paddling, and (c) video-conferencing platforms. In addition, we identified three key impacts: (a) feasibility and accessibility; (b) physical, psychosocial, and cognitive benefits; and (c) adaptations necessary for persons with dementia or MCI. Our study suggests that technology-based group exercise interventions are feasible and acceptable to persons with dementia or MCI. Future studies should involve individuals with dementia and their caregivers in the design and implementation of technology-based group exercise programs.

Evaluation of the accuracy of a UWB tracker for in-home positioning for older adults

The population of older adults is rapidly growing. In-home monitoring systems have been used to support aging-in-place. Ambient sensors or wearable localizers can be used but may be too low resolution, while camera systems are invasive to privacy. Ultra-wideband (UWB) localization offers precise positioning by placing anchors throughout the house and wearing a tag that is tracked by the anchors. In this study, the accuracy of UWB for indoor tracking was evaluated in a motion capture gait lab and in a mock condo in the Glenrose Rehabilitation Hospital. First, the configuration of UWB was tested, changing factors related to sampling time, anchor placement and line-of-sight. Comparing these factors to the configurations recommended by the manufacturer guidelines, accuracies remained within 14 cm. We then performed static and dynamic accuracy tests, with dynamic testing comprised of rolling and walking motions. In the motion capture lab, we found localization accuracies of 7.0 ± 11.1 cm while in the mock condo, we found accuracies of 27.3 ± 12.9 cm. Dynamic testing with rolling motions had an average of 19.1 ± 1.6 cm while walking was 20.5 ± 4.2 cm. The mean accuracy of UWB is within the 30 cm target for indoor localization.

Cumulative Anticholinergic Burden and its Predictors among Older Adults with Alzheimer's Disease Initiating Cholinesterase Inhibitors

BACKGROUND

Cumulative anticholinergic burden refers to the cumulative effect of multiple medications with anticholinergic properties. However, concomitant use of cholinesterase inhibitors (ChEIs) and anticholinergic burden can nullify the benefit of the treatment and worsen Alzheimer's disease (AD). A literature gap exists regarding the extent of the cumulative anticholinergic burden and associated risk factors in AD. Therefore, this study evaluated the prevalence and predictors of cumulative anticholinergic burden among patients with AD initiating ChEIs.

METHODS

A retrospective longitudinal cohort study was conducted using the Medicare claims data involving parts A, B, and D from 2013 to 2017. The study sample included older adults (65 years and older) diagnosed with AD and initiating ChEIs (donepezil, rivastigmine, or galantamine). The cumulative anticholinergic burden was calculated based on the Anticholinergic Cognitive Burden scale and patient-specific dosing using the defined daily dose over the 1 year follow-up period after ChEI initiation. Incremental anticholinergic burden levels were dichotomized into moderate-high (sum of standardized daily anticholinergic exposure over a year (TSDD) score ≥ 90) versus low-no (score 0-89). The Andersen Behavioral Model was used as the conceptual framework for selecting the predictors under the predisposing, enabling, and need categories. A multivariable logistic regression model was used to evaluate the predictors of high-moderate versus low-no cumulative anticholinergic burden. A multinomial logistic regression model was also used to determine the factors associated with patients having moderate and high burdens compared to low/no burdens.

RESULTS

The study included 222,064 older adults with AD with incident ChEI use (mean age 82.24 ± 7.29, 68.9% females, 83.6% White). Overall, 80.48% had some anticholinergic burden during the follow-up, with 36.26% patients with moderate (TSDD scores 90-499), followed by 24.76% high (TSDD score > 500), and 19.46% with low (TSDD score 1-89) burden categories. Predisposing factors such as age; African American, Asian, or Hispanic race; and need factors included comorbidities such as dyslipidemia, syncope, delirium, fracture, pneumonia, epilepsy, and claims-based frailty index were less likely to be associated with the moderate-high anticholinergic burden. The factors that increased the odds of moderate-high burden were predisposing factors such as female sex; enabling factors such as dual eligibility and diagnosis year; and need factors such as baseline burden, behavioral and psychological symptoms of dementia, depression, insomnia, urinary incontinence, irritable bowel syndrome, anxiety, muscle spasm, gastroesophageal reflux disease, heart failure, and dysrhythmia. Most of these findings remained consistent with multinomial logistic regression.  CONCLUSION: Four out of five older adults with AD had some level of anticholinergic burden, with over 60% having moderate-high anticholinergic burden. Several predisposing, enabling, and need factors were associated with the cumulative anticholinergic burden. The study findings suggest a critical need to minimize the cumulative anticholinergic burden to improve AD care.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSION

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

Ethical issues in long-term care settings: Care workers' lived experiences

BACKGROUND

Professional care workers face ethical issues in long-term care settings (LTCS) for older adults. They need to be independent and responsible, despite limited resources, a shortage of skilled professionals, global and societal changes, and the negative reputation of LTCS work.

RESEARCH AIM

Our aim was to describe the care workers' lived experiences of ethical issues. The findings can be used to gain new perspectives and to guide decision-making to improve the quality of care, occupational well-being and nursing education.

RESEARCH DESIGN

Focus group interviews were analyzed using a hermeneutic-phenomenological method. The analysis comprised three steps: naïve reading, structural analysis, and comprehensive understanding.

PARTICIPANTS AND RESEARCH CONTEXT

We randomly sampled LTCS service providers in Finland and 53 care workers with different educational backgrounds from seven organizations participated in focus group interviews in 2021.

ETHICAL CONSIDERATIONS

This was a sensitive study, which was connected to the participants' individual views of the world, professional ethics and social and health care legislation. The participants' provided informed consent and their anonymity was guaranteed.

FINDINGS

Care workers spoke about their lived experiences of ethical issues in an emotional way, using practical examples. They talked about how they were experts at caring and advocating for residents, balanced the responsibilities of their different roles, and defended their work to the wider society. The care workers said that ethical aspects of their work were too difficult to solve on their own. There were elements of their working environment and practices that caused unnecessary strain and they needed the commitment of managers, organizations, and society to solve ethical issues in LTCS.

CONCLUSIONS

Ethical issues were related to the well-being of both residents and care workers and reflected both internal and external pressures. Some issues could not be resolved by individuals and needed input from managers, organizations, and society.

Neuropsychiatric Manifestations in Alzheimer's Disease Patients: Genetics and Treatment Options

BACKGROUND

Alzheimer's disease (AD) is characterized by neuropsychiatric symptoms (NPS), which cause great misery to those with dementia and those who care for them and may lead to early institutionalization.

OBJECTIVE

The present systematic review aims to discuss the various aspects of Alzheimer's, including treatment options.

METHODS

The databases Embase, PubMed, and Web of Science were searched to collect data.

RESULTS

Incipient cognitive deterioration is commonly accompanied by these early warning signals of neurocognitive diseases. The neurobiology of NPSs in Alzheimer's disease, as well as particular symptoms, including psychosis, agitation, apathy, sadness, and sleep disorders, will be examined in this review. For NPSs in Alzheimer's disease, clinical trial designs, as well as regulatory issues, were also addressed. A fresh wave of research, however, is helping to push the discipline ahead. For medication development and repurposing, we highlight the most recent results in genetics, neuroimaging, and neurobiology. Even though identifying and treating psychosis in adults with dementia is still a challenging endeavor, new options are coming up that give the field fresh focus and hope. Conclsuion: It can be concluded from the complete literature survey that Alzheimer's-related psychosis as well as other symptoms that are not psychotic, have made significant progress in the last decade. These milestones in the development of safer, more effective treatments have been achieved as a consequence of great focus on non-pharmacological interventions like DICE or WHELD; the investigation into ways to improve existing drugs like aripiprazole, risperidone, amisulpride, and Escitalopram for safer precision-based treatment; and the development of a clinical trial program for pimavanserin.

Factors that can influence neurocognitive performance: a case study in a controlled environment

This is a case study of a patient in her 50s who presents with severe malnutrition, alcohol dependence, and untreated Bipolar Affective Disorder. She was hospitalized multiple times and placed in a group home 1 year after symptom onset. Cognitive and functional improvements are observed over a 6-year period, as demonstrated by 3 comprehensive neuropsychological evaluations. Residing in a monitored and structured environment for 6 years, with stability in psychiatric medications, monitored nutrition and abstinence from alcohol are attributed to this improvement. This study provides unique evidence of the impact of balanced nutrition and improvements in psychiatric symptoms on cognition.

Malnutrition and neuropsychiatric symptoms in dementia: the Cache County Dementia Progression Study

OBJECTIVES

Among people with dementia, poor nutritional status has been associated with worse cognitive and functional decline, but few studies have examined its association with neuropsychiatric symptoms (NPS). We examined this topic in a population-based sample of persons with dementia.

DESIGN

Longitudinal, observational cohort study.

SETTING

Community.

PARTICIPANTS

Two hundred ninety-two persons with dementia (71.9% Alzheimer's disease, 56.2% women) were followed up to 6 years.

MEASUREMENTS

We used a modified Mini-Nutritional Assessment (mMNA) and the Neuropsychiatric Inventory (NPI) to evaluate nutritional status and NPS, respectively. Individual linear mixed effects models examined the associations between time-varying mMNA total score or clinical categories (malnourishment, risk for malnourishment, or well-nourished) and NPI total score (excluding appetite domain) or NPI individual domain or cluster (e.g. psychosis) scores. Covariates tested were dementia onset age, type, and duration, medical comorbidities, sex, apolipoprotein E (APOE) genotype, and education.

RESULTS

Compared to the well-nourished, those at risk for malnourishment and those malnourished had higher total NPI scores [b (95% CI) = 1.76 (0.04, 3.48) or 3.20 (0.62, 5.78), respectively], controlling for significant covariates. Higher mMNA total score (better nutritional status) was associated with lower total NPI [b (95% CI) = -0.58 (-0.86, -0.29)] and lower domain scores for psychosis [b (95% CI) = -0.08 (-0.16, .004)], depression [b (95% CI = -0.11 (-0.16, -0.05], and apathy [b (95% CI = -0.19 (-0.28, -0.11)].

CONCLUSIONS

Worse nutritional status is associated with more severe NPS. Dietary or behavioral interventions to prevent malnutrition may be beneficial for persons with dementia.

Patient Polypharmacy use Following a Multi-Disciplinary Dementia Care Program in a Memory Clinic: A Retrospective Cohort Study

Introduction

Dementia increases the risk of polypharmacy. Timely detection and optimal care can stabilize or delay the progression of dementia symptoms, which may in turn reduce polypharmacy. We aimed to evaluate the change in polypharmacy use among memory clinic patients living with dementia who participated in a dementia care program compared to those who did not. We hypothesized that patients in the dementia care program would reduce their use of polypharmacy compared to those who were not in standard care.

Methods

We retrospectively analyzed data extracted from electronic medical records from a university memory clinic. Data from a total of 381 patients were included in the study: 107 in the program and 274 matched patients in standard care. We used adjusted odds ratios to assess the association between enrollment in the program and polypharmacy use at follow-up (five or more concurrent medications), controlling for baseline polypharmacy use and stratified polypharmacy use by prescription and over-the-counter (OTC).

Results

The two groups did not differ in the use of five or more overall and prescription medications at follow-up, controlling for the use of five or more of the respective medications at baseline and covariates. Being in the program was associated with a three-fold lower odds of using five or more OTC medications at follow-up (adjusted odds ratio = 0.30; p <0.001; 95% Confidence interval = 0.15-0.58) after controlling for using five or more OTC medications at baseline and covariates.

Conclusions

Dementia care may reduce polypharmacy of OTC medications, potentially reducing risky drug-drug interactions. More research is needed to infer causality and understand how to reduce prescription medication polypharmacy.

Cost effectiveness of non-drug interventions that reduce nursing home admissions for people living with dementia

INTRODUCTION

Six million Americans live with Alzheimer's disease and Alzheimer's disease and related dementias (AD/ADRD), a major health-care cost driver. We evaluated the cost effectiveness of non-pharmacologic interventions that reduce nursing home admissions for people living with AD/ADRD.

METHODS

We used a person-level microsimulation to model the hazard ratios (HR) on nursing home admission for four evidence-based interventions compared to usual care: Maximizing Independence at Home (MIND), NYU Caregiver (NYU); Alzheimer's and Dementia Care (ADC); and Adult Day Service Plus (ADS Plus). We evaluated societal costs, quality-adjusted life years and incremental cost-effectiveness ratios.

RESULTS

All four interventions cost less and are more effective (i.e., cost savings) than usual care from a societal perspective. Results did not materially change in 1-way, 2-way, structural, and probabilistic sensitivity analyses.

CONCLUSION

Dementia-care interventions that reduce nursing home admissions save societal costs compared to usual care. Policies should incentivize providers and health systems to implement non-pharmacologic interventions.

Designing dementia care activation program for Filipino American caregivers

OBJECTIVE

This research study aims to identify the fundamental components of community adaptation for a culturally tailored care partner activation program for Filipino American family caregivers of patients with Alzheimer's Disease and related dementia (ADRD).

DESIGN

The study utilized focus group interviews with community nurse leaders, stakeholders, and family caregivers of patients with ADRD.

RESULTS

The research revealed that education and knowledge about the disease, community-based services and facilities, support groups and resources, spiritual and cultural values, and access to transportation are all critical components for community adaptation.

CONCLUSION

The findings suggest that a culturally tailored care partner activation program that incorporates these components can enhance the quality of life for Filipino American caregivers and their loved ones with ADRD. The nursing implications of the study underscore the importance of nurses being culturally competent and sensitive to the unique challenges faced by Filipino American caregivers. Nurses can provide valuable support to caregivers by educating them, connecting them with community resources, and advocating for culturally responsive care practices.

American Geriatrics Society 2023 updated AGS Beers Criteria® for potentially inappropriate medication use in older adults

The American Geriatrics Society (AGS) Beers Criteria® (AGS Beers Criteria®) for Potentially Inappropriate Medication (PIM) Use in Older Adults is widely used by clinicians, educators, researchers, healthcare administrators, and regulators. Since 2011, the AGS has been the steward of the criteria and has produced updates on a regular cycle. The AGS Beers Criteria® is an explicit list of PIMs that are typically best avoided by older adults in most circumstances or under specific situations, such as in certain diseases or conditions. For the 2023 update, an interprofessional expert panel reviewed the evidence published since the last update (2019) and based on a structured assessment process approved a number of important changes including the addition of new criteria, modification of existing criteria, and formatting changes to enhance usability. The criteria are intended to be applied to adults 65 years old and older in all ambulatory, acute, and institutionalized settings of care, except hospice and end-of-life care settings. Although the AGS Beers Criteria® may be used internationally, it is specifically designed for use in the United States and there may be additional considerations for certain drugs in specific countries. Whenever and wherever used, the AGS Beers Criteria® should be applied thoughtfully and in a manner that supports, rather than replaces, shared clinical decision-making.

Quality of Nursing Homes Among ADRD Residents Newly Admitted From the Community: Does Race Matter?

OBJECTIVE

To examine racial differences in admissions to high-quality nursing homes (NHs) among residents with Alzheimer disease and related dementias (ADRD), and whether such racial differences can be influenced by dementia-related state Medicaid add-on policies.

DESIGN

Retrospective cross-sectional study.

SETTING AND PARTICIPANTS

The study included 786,096 Medicare beneficiaries with ADRD newly admitted from the community to NHs between January 1, 2011 and December 31, 2017.

METHODS

2010-2017 Minimum Data Set 3.0, Medicare Beneficiary Summary File, Medicare Provider Analysis and Review, and Nursing Home Compare data were linked. For each individual, we constructed a "choice" set of NHs based on the distance between the NH and an individual residential zip code. McFadden's choice models were estimated to examine the relationship between admission into a high-quality (4- or 5-star) NH and individual characteristics, specifically race, and state Medicaid dementia-related add-on policies.

RESULTS

Among the identified residents, 89% were White, and 11% were Black. Overall, 50% of White and 35% of Black individuals were admitted to high-quality NHs. Black individuals were more likely to be Medicare-Medicaid dually eligible. Results from McFadden's model suggested that Black individuals were less likely to be admitted to a high-quality NH than White individuals (OR = 0.615, P < .01), and such differences were partially explained by some individual characteristics. Furthermore, we found that the racial difference was reduced in states with dementia-related add-on policies, compared with states without these policies (OR = 1.16, P < .01).

CONCLUSIONS AND IMPLICATIONS

Black individuals with ADRD were less likely to be admitted to high-quality NHs than White individuals. Such difference was partially related to individuals' health conditions, social-economic status, and state Medicaid add-on policies. Policies to reduce barriers to high-quality NHs among Black individuals are necessary to mitigate health inequity in this vulnerable population.

Determinants of informal care time, distress, depression, and quality of life in care partners along the trajectory of Alzheimer's disease

Introduction

We evaluated determinants associated with care partner outcomes along the Alzheimer's disease (AD) stages.

Methods

We included n = 270 care partners of amyloid-positive patients in the pre-dementia and dementia stages of AD. Using linear regression analysis, we examined determinants of four care partner outcomes: informal care time, caregiver distress, depression, and quality of life (QoL).

Results

More behavioral symptoms and functional impairment in patients were associated with more informal care time and depressive symptoms in care partners. More behavioral symptoms were related with more caregiver distress. Spouse care partners spent more time on informal care and QoL was lower in female care partners. Behavioral problems and subtle functional impairment of the patient predisposed for worse care partner outcomes already in the pre-dementia stages.

Discussion

Both patient and care partner determinants contribute to the care partner outcomes, already in early disease stages. This study provides red flags for high care partner burden.

A 2023 update on the advancements in the treatment of agitation in Alzheimer's disease

INTRODUCTION

Neuropsychiatric symptoms (NPS) in Alzheimer's Disease (AD) are associated with negative outcomes for patients and their care partners. Agitation is one of the most common and distressing NPS, yet we lack safe and effective treatment options. While nonpharmacologic interventions are considered first line treatment, these may not be effective or appropriate for every patient. Our current approaches to the pharmacologic treatment of agitation in AD consist of the off-label use of antipsychotics, sedative/hypnotics, anxiolytics, mood-stabilizing anticonvulsants, acetylcholinesterase inhibitors, NMDA receptor antagonists, and antidepressants. Despite their prevalent use, they have questionable efficacy and significant safety concerns.

AREAS COVERED

Advances in the understanding of neurobiological mechanisms of agitation have fueled recent clinical trials. This article is an update to our 2017 review. A comprehensive search of ClinicalTrials.gov was completed from January 2017 to June 2022 using the search terms "Alzheimer's Disease" and "Agitation". A subsequent scoping review was completed in PubMed and Google Scholar. Several agents were identified for promise in treating agitation, including: brexpiprazole, cannabinoids, dexmedetomidine, dextromethorphan, escitalopram, masupirdine, and prazosin.

EXPERT OPINION

Clinical trials remain underway utilizing both novel and repurposed agents to address symptoms of agitation in AD. With increasing understanding of the neurobiological mechanisms that fuel the development of agitation in AD, the use of enhanced trial design and conduct, advanced statistical approaches, and accelerated pathways for regulatory approval, we are advancing closer to having safe and efficacious treatment options for agitation in AD.

[Déterminants du succès d'une démarche provinciale d'usage optimal des antipsychotiques chez les résidents en soins de longue durée selon les acteurs clés impliqués dans l'implantation]

Le Québec présente le taux de prescriptions d'antipsychotiques le plus élevé chez les personnes âgées de 65 ans et plus au Canada. La démarche « Optimiser les pratiques, les usages, les soins et les services - antipsychotiques » (OPUS-AP) vise à pallier cet enjeu. Étant donné ses premiers résultats prometteurs, notre étude visait à identifier les déterminants de son succès. Elle repose sur un devis d'étude de cas regroupant une analyse documentaire et 21 entrevues auprès d'acteurs clés impliqués dans l'implantation. Les résultats mettent en lumière cinq déterminants centraux : 1) une démarche intégrée, collaborative et probante; 2) des communications et des réseaux au service de la démarche; 3) un climat d'implantation favorable aux changements; 4) un engagement et une implication des parties prenantes; et 5) une stratégie d'application des connaissances intégrée et appuyée. Des défis et recommandations pour assurer la pérennisation et la mise à l'échelle d'OPUS-AP et inspirer des démarches similaires sont identifiés.

Radiographers' knowledge and attitudes toward dementia

INTRODUCTION

Dementia is a syndrome associated with a decline in brain function, impacting how we speak, think, feel, and behave. Misunderstanding of dementia and how it affects patients and their carers is common. There is limited research on how radiographers provide adequate care to those with dementia. Radiographers with knowledge and positive attitudes can reduce stigma and fear, improving the quality of care. This study aimed to assess radiographers' knowledge and attitudes towards dementia.

METHODS

A cohort of registered radiographers in Ireland participated in an online survey. Two pre-existing validated questionnaires: The Alzheimer's Disease Knowledge Scale (ADKS) and the Dementia Attitudes Scale (DAS), assessed radiographers' knowledge and attitudes towards dementia and people with dementia. Scores were compared across variables such as gender, age, grade, qualification, work setting, and the number of years qualified.

RESULTS

A total of 123 radiographers responded. Knowledge scores did not significantly differ across demographic groups (p > 0.05). Total knowledge scores ranged from 60% to 100%. Total attitude scores ranged from 50% to 100%. Participants with a BSc, MSc, and other post-graduate degrees scored higher on the attitude scale than those with a diploma qualification (p = 0.027). Those with less than 20 years' experience scored higher than those with more. Knowledge had little correlation with attitude (r = 0.0522; p = 0.5667).

CONCLUSION

Findings indicate variations in attitudes linked to age and experience, and some misconceptions can be observed across varying groups. Interventions to improve attitudes and raise awareness are needed.

IMPLICATIONS FOR PRACTICE

There is a need for further research and education on dementia care in the imaging department. We have identified areas requiring further education.

Leveraging genetic diversity in mice to inform individual differences in brain microstructure and memory

In human Alzheimer's disease (AD) patients and AD mouse models, both differential pre-disease brain features and differential disease-associated memory decline are observed, suggesting that certain neurological features may protect against AD-related cognitive decline. The combination of these features is known as brain reserve, and understanding the genetic underpinnings of brain reserve may advance AD treatment in genetically diverse human populations. One potential source of brain reserve is brain microstructure, which is genetically influenced and can be measured with diffusion MRI (dMRI). To investigate variation of dMRI metrics in pre-disease-onset, genetically diverse AD mouse models, we utilized a population of genetically distinct AD mice produced by crossing the 5XFAD transgenic mouse model of AD to 3 inbred strains (C57BL/6J, DBA/2J, FVB/NJ) and two wild-derived strains (CAST/EiJ, WSB/EiJ). At 3 months of age, these mice underwent diffusion magnetic resonance imaging (dMRI) to probe neural microanatomy in 83 regions of interest (ROIs). At 5 months of age, these mice underwent contextual fear conditioning (CFC). Strain had a significant effect on dMRI measures in most ROIs tested, while far fewer effects of sex, sex*strain interactions, or strain*sex*5XFAD genotype interactions were observed. A main effect of 5XFAD genotype was observed in only 1 ROI, suggesting that the 5XFAD transgene does not strongly disrupt neural development or microstructure of mice in early adulthood. Strain also explained the most variance in mouse baseline motor activity and long-term fear memory. Additionally, significant effects of sex and strain*sex interaction were observed on baseline motor activity, and significant strain*sex and sex*5XFAD genotype interactions were observed on long-term memory. We are the first to study the genetic influences of brain microanatomy in genetically diverse AD mice. Thus, we demonstrated that strain is the primary factor influencing brain microstructure in young adult AD mice and that neural development and early adult microstructure are not strongly altered by the 5XFAD transgene. We also demonstrated that strain, sex, and 5XFAD genotype interact to influence memory in genetically diverse adult mice. Our results support the usefulness of the 5XFAD mouse model and convey strong relationships between natural genetic variation, brain microstructure, and memory.

Primary Care Provider Preferences on Dementia Training: A Qualitative Study

BACKGROUND

Dementia has no cure, but interventions can stabilize the progression of cognitive, functional, and behavioral symptoms. Primary care providers (PCPs) are vital for the early detection, and long-term management of these diseases, given their gatekeeping role in the healthcare system. However, PCPs rarely implement evidence-based dementia care due to time limitations and knowledge about diagnosis and treatment. Training PCPs may help address these barriers.

OBJECTIVE

We explored the preferences of PCPs for dementia care training programs.

METHODS

We conducted qualitative interviews with 23 PCPs recruited nationally via snowball sampling. We conducted remote interviews and organized the transcripts for qualitative review to identify codes and themes, using thematic analysis methods.

RESULTS

PCP preferences varied regarding many aspects of ADRD training. Preferences varied regarding how to best increase PCP participation in training, and what content and materials were needed to help them and the families they serve. We also found differences regarding the duration and timing of training, and the modality of training sessions (remote versus in-person).

CONCLUSION

The recommendations arising from these interviews have the potential to inform the development and refinement of dementia training programs to optimize their implementation and success.

Respectful Caring for the Agitated Elderly (ReCAGE): A Multicentre, Prospective, Observational Study to Evaluate the Effectiveness of Special Care Units for People with Dementia

BACKGROUND

Behavioral and psychological symptoms of dementia (BPSD) bring complexity in the clinical management of people with dementia; therefore, it is important to evaluate different models of care, such as Special Care Units (SCU-B).∥Objective:To evaluate the SCU-B effectiveness toward alleviating BPSD and improving the quality of life (QoL) of patients and their caregivers.∥Methods:ReCAGE was a multicenter, controlled, longitudinal study where 508 patients with BPSD were enrolled in two cohorts: 262 patients from centers endowed with a SCU-B, and 246 from centers without SCU-B. Statistical analyses included factorial ANCOVA for comparison among centers. The primary endpoint was effectiveness of the SCU-B, measured through the Neuropsychiatric Inventory (NPI) changes. Secondary endpoints were change in QoL of patients and caregivers, and the tertiary endpoint was time to nursing home admission.∥Results:The NPI scores decreased in both arms, with a statistically significant difference from baseline to 36 months (p < 0.0001) in both cohorts. Over time, NPI decreased more steeply during the first year in the SCU-B arm, but in the following two years the slope was clearly in favor of the control arm. This different pattern of the two cohorts reached statistical significance at the interaction "cohort by time" (p < 0.0001). Conflicting results were found regarding the outcomes of quality of life, while there were no differences in time to institutionalization in both cohorts.∥Conclusion:The RECage study did not confirm the long-term superiority of the pathway comprising a SCU-B. A post-hoc analysis revealed data supporting their acute effectiveness during behavioral crises.

Family Caregivers of People with Dementia Associate with Poor Health-Related Quality of Life: A Nationwide Population-Based Study

Despite the growing awareness of poor health-related quality of life (HRQoL) in family caregivers of people with dementia (PWD), their relationship has rarely been explored with population-based samples. The current cross-sectional study aimed to determine the detrimental impact of informal dementia caregiving on HRQoL by using nationally representative population-based samples from the Korean Community Health Survey. Demographics, socioeconomic, and physical and mental health-related characteristics as well as HRQoL measured by the Korean version of the European Quality of Life Questionnaire Five Dimension (EQ-5D) were compared between 9563 family caregivers of PWD and 186,165 noncaregivers. Caregivers had lower index scores and higher frequency of some/extreme problems in all five dimensions of the EQ-5D compared with noncaregivers. Logistic regression adjusting for potential confounding factors found that caregivers had a higher frequency of poor HRQoL (lowest quartile of EQ-5D index) than noncaregivers (adjusted odds ratio [95% confidence interval] = 1.46 [1.39-1.53]). Compared to noncaregivers, caregivers had a higher frequency of some/extreme problems in each dimension of the EQ-5D: mobility (1.30 [1.21-1.40]), self-care (1.62 [1.46-1.80]), usual activity (1.39 [1.29-1.51]), pain/discomfort (1.37 [1.31-1.45]), and anxiety/depression (1.51 [1.42-1.61]). A one-to-one propensity score matching analysis confirmed that poor HRQoL was more frequently found in caregivers compared to noncaregivers (1.38 [1.29-1.48]). Our results indicated that family caregivers of PWD are significantly associated with overall poor HRQoL, underscoring the detrimental impact of informal dementia caregiving on HRQoL. Given the high frequency of poor HRQoL in dementia caregivers and the important recognition of its serious consequences on physical and mental health, clinicians should take into consideration efficient interventions to improve health and HRQoL for family caregivers of PWD.

Factors associated with formal and informal resource utilization in nursing home patients with and without dementia: cross-sectional analyses from the COSMOS trial

OBJECTIVES

To investigate the association between clinical, demographic, and organizational factors and formal (health professionals) and informal (relatives) resource utilization in nursing home patients with and without dementia.

METHODS

Baseline data from the multicomponent cluster randomized control COSMOS trial including 33 Norwegian nursing homes and 723 residents with and without dementia. Nursing home staff (n = 117) participated as proxy raters to approximate formal and informal resource use in daily care.

MEASUREMENTS

The primary outcome was the Resource Utilization in Dementia - Formal Care scale to assess formal and informal care time in hours/month regarding basic activities of daily living (ADL), instrumental ADL, and supervision. Secondary outcomes were hours/week spent on formal and informal leisure activities. Behavioral and psychological symptoms in dementia (BPSD) were assessed by the Neuropsychiatric Inventory-Nursing Home version, physical function by the Physical Self-Maintenance Scale, and psychotropic drug use by the Anatomical Therapeutic Chemical classification system. Organizational factors were ward size and staff ratio.

RESULTS

Generalized linear mixed-effect models and two-part modelling revealed an association between increased formal care time and poorer physical function, higher agitation and psychotropic drug use and lower cognitive function (all p < .05). Enhanced formal leisure time was related to better ADL function (p < .05) and smaller wards (p < .05). The family related leisure time was associated with agitation, decline in ADL function, smaller wards, and better staffing ratio (all p < .05). Married patients received more informal direct care (p < .05) and leisure time (p < .05) compared to unmarried/widowed.

CONCLUSION

For nursing home staff, higher agitation and psychotropic drug use, and lower cognitive function, is associated with more direct care time, whereas leisure time activities are less prioritized in people with lower physical function. Informal caregivers' engagement is encouraged by smaller nursing homes and better staff ratio. Therefore, we recommend stakeholders and healthcare professionals to consider these clinical and organizational factors to optimize treatment and leisure time activities in nursing home patients with various needs.

Differential race effects of the tailored activity program (TAP) on dementia-related behaviors: A randomized controlled trial

BACKGROUND

Although nonpharmacological approaches are considered first-line treatments for dementia-related behaviors, it is unclear as to their effectiveness for different racial groups. We evaluated the effects of the Tailored Activity Program (TAP) on agitated and aggressive behaviors in Black and White families.

METHODS

We conducted a single-blind, two-arm randomized controlled trial involving Black (N = 90) and White (N = 145) families. TAP involved eight home sessions by occupational therapists who provided activities tailored to abilities and interests and instructed caregivers in their use over 3 months. An attention control group received eight sessions by research assistants who provided disease education and home safety tips. Measures included caregiver ratings of frequency by severity for the agitation and aggression subscales of the Neuropsychiatric Inventory-Clinician (NPI-C) at 3 months (main trial primary outcome), number of completed sessions and time spent, changes in behavioral subcomponents of the subscales (frequency, severity, caregiver distress), and percent improving/worsening.

RESULTS

Black and White families completed similar numbers of treatment sessions, but White dyads averaged nearly two contact hours more than Black dyads (p = 0.008). At 3 months, an interaction effect (treatment by race) indicated significantly greater reductions in frequency by severity scores for the agitation and aggression subscales for Black TAP dyads versus White TAP dyads and White and Black attention control dyads. Also, significant interaction effects favoring TAP Black dyads were observed for select behavioral components. For TAP dyads with elevated baseline agitation/aggression levels (N = 71), 34.5% of Black versus 11.9% of White dyads improved; whereas 2.6% of Black versus 16.7% of White dyads had worsened agitation/aggression scores.

CONCLUSION

Black families compared to White families derived greater behavioral benefits from TAP for PLWD at 3 months despite having less treatment exposure. Examining differential race effects may enhance precision in using nonpharmacological approaches and promote equity in dementia care for underserved populations.

Global, regional, and national burden of Alzheimer's disease and other dementias, 1990-2019

BACKGROUND

With the increase in the aging population worldwide, Alzheimer's disease has become a rapidly increasing public health concern. Monitoring the dementia disease burden will support health development strategies by providing scientific data.

METHODS

Based on the data obtained from the 2019 Global Burden of Disease (GBD) database, the numbers and age-standardized rates (ASRs) of incidence, prevalence, death, and disability-adjusted life-years (DALYs) of Alzheimer's disease and other dementias from 1990 to 2019 were analyzed. Calculated estimated annual percentage changes (EAPCs) and Joinpoint regression analyses were performed to evaluate the trends during this period. We also evaluated the correlations between the epidemiology and the sociodemographic index (SDI), an indicator to evaluate the level of social development in a country or region considering the education rate, economic situation, and total fertility rate.

RESULTS

From 1990 to 2019, the incidence and prevalence of Alzheimer's disease and other dementias increased by 147.95 and 160.84%, respectively. The ASR of incidence, prevalence, death, and DALYs in both men and women consistently increased over the study period. All the ASRs in women were consistently higher than those in men, but the increases were more pronounced in men. In addition, the ASRs of incidence, prevalence, and DALYs were positively correlated with the SDI. Moreover, the proportion of patients over 70 years old with dementia was also positively correlated with the SDI level. Smoking was a major risk factor for the disease burden of dementia in men, while obesity was the major risk factor for women.

CONCLUSION

From 1990 to 2019, the Alzheimer's disease burden increased worldwide. This trend was more serious in high-SDI areas, especially among elderly populations in high-SDI areas, who should receive additional attention. Policy-makers should take steps to reverse this situation. Notably, women were at a higher risk for the disease, but the risk in men showed a faster increase. We should give attention to the aging population, attach importance to interventions targeting dementia risk factors, and formulate action plans to address the increasing incidence of dementia.

What matters when it comes to measuring Age-Friendly Health System transformation

Thousands of health systems are now recognized as "Age-Friendly Health Systems," making this model one of the most widely disseminated - and most promising- models to redesign care delivery for older adults. Sustaining these gains will require demonstrating the impact on care delivery and outcomes of older adults. We propose a new measurement model to more tightly link Age-Friendly Health System transformation to outcomes within each "M" (What Matters, Medications, Mobility, and Mentation). We evaluated measures based on the following characteristics: (1) conceptual responsiveness to changes brought about by practicing "4Ms" care; (2) degree to which they represent outcomes that matter to older adults; and (3) how they can be feasibly, reliably, and validly measured. We offer specific examples of how novel measures are currently being used where available. Finally, we present measures that could capture system-level effects across "M"s. We tie these suggestions together into a conceptual measurement model for AFHS transformation, with the intent to spur discussion, debate, and iterative improvement in measures over time.

A Call for Drug Therapies for the Treatment of Social Behavior Disorders in Dementia: Systematic Review of Evidence and State of the Art

Growing evidence supports the presence of social cognition deficits and social behavior alterations in major and minor neurocognitive disorders (NCDs). Even though the ability to identify socio-emotional changes has significantly improved in recent years, there is still no specific treatment available. Thus, we explored evidence of drug therapies targeting social cognition alterations in NCDs. Papers were selected according to PRISMA guidelines by searching on the PubMed and Scopus databases. Only papers reporting information on pharmacological interventions for the treatment of social cognition and/or social behavioral changes in major and/or minor NCDs were included. Among the 171 articles entered in the paper selection, only 9 papers were eligible for the scope of the review. Trials testing pharmacological treatments for socio-emotional alterations in NCDs are poor and of low-medium quality. A few attempts with neuroprotective, psychoactive, or immunomodulating drugs have been made. Oxytocin is the only drug specifically targeting the social brain that has been tested with promising results in frontotemporal dementia. Its beneficial effects in long-term use have yet to be evaluated. No recommendation can currently be provided. There is a long way to go to identify and test effective targets to treat social cognition changes in NCDs for the ultimate benefit of patients and caregivers.

Occupational Therapy Interventions for Dementia Caregivers: Scoping Review

BACKGROUND AND PURPOSE

caregivers of people with dementia (PwD) often experience a significant caregiver burden. Occupational Therapy (OT) is a helpful discipline for improving quality of life and other health factors for these caregivers. We conducted a Scoping Review to describe OT interventions for caregivers of PwD.

METHODS

two authors searched PubMed, Scopus, EMBASE and Web of Science databases and OT journals indexed in the Journal Citation Reports. Terms included in the search strategy were: dementia, Alzheimer, Parkinson, caregivers and OT. We included articles with experimental design in which an OT intervention in caregivers of PwD was carried out, written in Spanish or English and with the full text available.

RESULTS

a total of 2121 articles were obtained, 31 of which were included; 22 of them described home-based OT interventions: Tailored Activity Program (TAP) (n = 5), Environmental Skill-Building Program (ESP) (n = 4) and Advancing Caregiver Training (ACT) (n = 3) and other household interventions (n = 10); the remaining studies described OT interventions in other settings (n = 9).

CONCLUSIONS

OT interventions for caregivers of PwD were mainly carried out at home. The most commonly used interventions were TAP focused on caregivers of people with Alzheimer's disease, aimed at lessening the burden, depression and stress experienced by caregivers.

The recognition and management of neuropsychiatric symptoms in early Alzheimer's disease: a qualitative study among Dutch memory clinic physicians

BACKGROUND

Timely recognition and treatment of neuropsychiatric symptoms (NPS) in Alzheimer's disease (AD) dementia may improve quality of life, reduce caregiver burden, and delay disease progression. However, management of NPS in early AD dementia remains challenging. To date, little is known about the specific challenges for memory clinic-based physicians. The aims of this qualitative study were to obtain insights regarding the recognition and treatment of NPS in AD dementia in the memory clinic, to identify challenges experienced by physicians while managing NPS, and to examine the attitudes of memory clinic physicians on the role of the memory clinic in the care for NPS in early AD dementia.

METHODS

Semi-structured interviews were conducted with 13 physicians working at a memory clinic in the Netherlands (n = 7 neurologist, n = 6 geriatrician, 46% female). The data were analyzed by two independent researchers using thematic analysis.

RESULTS

We observed large variation among Dutch memory clinic physicians regarding care practices, expertise, and attitudes on the role of the memory clinic considering NPS in AD dementia. The most prominent challenges that memory clinic physicians experienced while managing NPS included that the outpatient setting complicates the recognition and treatment of NPS, a lack of experience, knowledge, and/or resources to adequately apply non-pharmacological interventions, and a lack of consensus among physicians on the role of the memory clinic in NPS recognition and management.

CONCLUSIONS

We identified challenges that need to be addressed to improve the early recognition and adequate management of NPS in AD dementia at the memory clinic.

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

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