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

Development of the Dardashna Checklist for Identifying Triggers of Behavioral Change in Individuals With Dementia: A Qualitative Study

The purpose of the current qualitative study was to describe the development of the Dardashna Checklist to clinically identify behavior change triggers in individuals with dementia. Semi-structured, in-depth, face-to-face interviews were conducted with four physicians and four experienced caregivers involved in the care of individuals with dementia. From analysis of participants' interviews, themes extracted included Triggers of Behavioral Change in Individuals With Dementia and Types of Behavioral Changes, using the checklist structure as a guide. The information gathered by this checklist conveys important messages to experienced physicians or caregivers who want to help less experienced caregivers or individuals with dementia. In this case, physicians' prescriptions and the responses of other experienced caregivers will be more targeted and useful. This checklist will help facilitate clinical care decisions, improve quality of life, reduce expenses and side effects of medications, and improve communication among persons with dementia, their caregivers, and health care providers.

Case Management-based Collaborative Care Model Associated with improvement in neuropsychiatric outcomes in community-dwelling people living with dementia

BACKGROUND

This study aimed to explore the association between adherence of collaborative care model and short-term deterioration of BPSD after controlling patient and caregiver factors.

METHODS

This retrospective case-control study enrolled 276 participants who were newly diagnosed with dementia and BPSD. A dementia collaborative care team interviewed patients and caregivers to form a care plan and provided individualized education or social resource referrals. A multivariate logistic regression model with backward selection was used to test factors associated with BPSD deterioration, defined as worse neuropsychiatric inventory (NPI) scores 1 year after joining the care model.

RESULTS

Male sex (odds ratio [OR] = 0.45; 95% confidence interval [CI] = 0.25-0.84) and higher clinical dementia rating scale sum of boxes scores (CDR-SOB) (OR = 0.90; 95% CI = 0.83-0.98) were protective factors, whereas spouse caregivers and withdrawals from the care model (OR = 3.42; 95% CI = 1.28-9.15) were risk factors for BPSD deterioration.

CONCLUSIONS

Our study showed that both patient and caregiver factors were associated with deterioration of BPSD. The case manager-centered dementia collaborative care model is beneficial for the management of BPSD. Healthcare systems may consider implementing a case management model in clinical dementia care practice.

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.

Application of virtual reality for dementia management

Age is recognized as the major factors of dementia, especially in for Alzheimer’s disease (AD). Given to the aged population, the increased number of demented population has been receiving a great impact in our society. Unfortunately, so far, no cured medicines have been demonstrated to provide effective treatment in AD. The combination of pharmacological and non-pharmacological interventions has been proposed to manage dementia with potential benefits especially in decreasing caregiver’s burden and behavior, as well as psychological problems of demented patients. Recently, giving to the glorious development in digital technologies, the virtual reality, one of the non-pharmacological interventions has been used extensively in dementia managements for its strengths which can be adapted in accordance with the heterogeneous needs from demented patients and their caregivers. However, various study designs and other reasons made these results difficult to be interpreted. In this review our goal is to provide a better understanding for these points.

Neuropsychiatric Symptoms of Alzheimer's Disease and Caregiver Burden

Introduction/Objectives

In addition to cognitive decline, one of the most important problems for caregivers of patients with Alzheimer's is neuropsychiatric symptoms (NPS). This study aimed to evaluate the NPS in patients with Alzheimer's disease (AD) and investigate its relationship with caregiver burden (CB).

Methods

In a cross-sectional study of 85 patients with AD referred to Shafa Hospital in Rasht and their caregivers in 2020, information was collected using a demographic questionnaire, Neuropsychiatric Inventory Questionnaire (NPI-Q), and the Caregiver Burden Inventory (CBI). Data were analyzed by Spearman correlation, t-test, and linear regression, with SPSS version 22.

Results

The mean age of the patients and their caregivers were 74.95 ± 8.87 years and 43.98 ± 11.38 years, respectively. The mean total score of NPS in patients with AD was 44.25 (0–144) and the mean CB score was 36.27 (0–96), which was a moderate level. According to the results, 91% of patients had apathy, while happiness/euphoria was reported as the most uncommon symptom. In addition, there was a significant relationship between the score of NPS and CB (r = 0.542, P < 0.0001), as well as all its sub-components, time-dependence burden with more correlation (r = 0.509, P < 0.0001), and social burden with less correlation (r = 0.352, P < 0.001). NPS, hallucination, aberrant motor behavior (AMB), delusion, and depression were most correlated with CB. Also, the mean score of CB was significantly higher in women than in men (P = 0.045). Living in a rural area had a significant relationship with NPS score (P = 0.026). Also, linear regression showed that with increasing 1 year of patients' age, the mean score of patient's NPS decreased by 0.374 (P = 0.048).

Conclusion

Neuropsychiatric symptoms, especially hallucination, aberrant motor behavior (AMB), delusion, and depression were associated with caregiver burden. Apathy was the most common symptom in patients with AD.

Validation of the Spanish Version of the Double Knowledge Expectations and Received Knowledge Significant Other Scale for Informal Caregivers of People with Dementia (KESO-DEM/RKSO-DEM)

Dementia is associated with cognitive decline. Becoming an informal caregiver raises questions, requiring information and support from health professionals to guide home care. A multicenter, longitudinal study was carried out to validate the Spanish version of the double scale of expected and received knowledge for informal caregivers of people with dementia (KESO-DEM/RKSO-DEM), the analysis of the dimensional structure of the instrument, its validity and reliability, and temporary stability was carried out. An analysis of criterion and construct validity, internal consistency, and test−retest stability was performed. The evaluation of the interrelation between dimensions was statistically significant. Regarding internal consistency, the scale values were good both for the scale totals and for each dimension of knowledge, with Cronbach’s alpha coefficients of 0.97. For criterion validity, all items showed temporal stability for both questionnaires (p < 0.05). The availability of a valid, reliable tool for the measurement of expected and received knowledge in caregivers of people with dementia allows an approach based on the real needs of the family and the patient. It is important to design care protocols for people with dementia that are adapted to their needs and expectations and to their non-curative treatment, to improve the emotional well-being of patients and informal caregivers.

Cannabis Use in Older Adults: A Perspective

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

Dyadic effects of family-functioning and resilience on quality of life in advanced lung cancer patients and caregivers: An actor-partner interdependence mediation model

PURPOSE

Lung cancer as a stressful event profoundly impacts the entire family, especially patients and their family caregivers. This study uses a dyadic analysis approach to explore the dyadic effects of family functioning on the quality of life (QoL), and whether resilience acts as a mediator in advanced lung cancer patient-caregiver dyads.

METHODS

This was a cross-sectional study, and 287 dyads of advanced lung cancer patients and their caregivers were enrolled. Family-functioning, resilience, and QoL were assessed by the General Functioning subscale of the Family Assessment Device (FAD), the 10-item Connor-Davidson Resilience Scale, and the Short Form-8 (SF-8) Health Survey, respectively. Data were analyzed using the actor-partner interdependence mediation model.

RESULTS

This study found that, for patients and caregivers, resilience mediates the actor effects of family-functioning on QoL. That is, family-functioning was positively related to their resilience, which improved QoL. Another important finding is that caregivers' family-functioning had significant indirect effects on patients' QoL through their resilience.

CONCLUSIONS

Positive family functioning perceived by patients and caregivers can improve their QoL by developing their own resilience. Furthermore, family-functioning perceived by caregivers can also improve patients' QoL through their resilience. Medical staff should identify vulnerable patients and caregivers with poorer family-functioning and resilience, and make focused intervention to improve the QoL of both lung cancer patients and their family caregivers.
