Risk Factors of Behavioral and Psychological Symptoms in Patients with Alzheimer Disease: The Clinical Research of Dementia of South Korea Study.

ABSTRACT: BACKGROUND:Few studies have evaluated risk factors for behavioral and psychological symptoms of dementia at the initial assessment for Alzheimer disease in large patient samples. In this study, the factors influencing Alzheimer disease were examined using the Clinical Research of Dementia of South Korea data. METHODS:This cross-sectional study was conducted using data of 1,128 patients with Alzheimer disease. The behavioral and psychological symptoms of dementia were examined using the Korean version of the Neuropsychiatric Inventory. Demographic characteristics, health-related behavior, neuropsychological tests, comorbidities, blood test results, and caregiver characteristics were assessed. Median logistic regression analysis with adjustment for covariates was conducted. RESULTS:The behavioral and psychological symptoms of dementia were negatively associated with memory (P=0.022) and frontal/executive (P<0.001) function in the Seoul Neuropsychological Screening Battery-dementia, Barthel Index for Activities of Daily Living (P<0.001), Korean version of the Mini-Mental State Examination score (P=0.003), and caregiver age (P=0.005) after adjustment for confounding factors, and positively associated with the Seoul-Instrumental Activities of Daily Living score (P<0.001), Clinical Dementia Rating Sum of Box (P<0.001), Global Deterioration Scale score (P<0.001), abnormality of free T4 level (P<0.001), anemia (P<0.001), and family history of stroke (P=0.001). Patients with female caregivers exhibited more severe behavioral and psychological symptoms of dementia than those with male caregivers. CONCLUSION:Behavioral and psychological symptoms of dementia in Alzheimer disease patients were associated with various risk factors including the inability to live independently and Alzheimer disease severity. These findings suggest that prevention and treatment strategies for the behavioral and psychological symptoms of dementia should be comprehensive.

Project description:BackgroundAlthough disclosing the predictors of different behavioral and psychological symptoms of dementia (BPSD) is the first step in developing person-centered interventions, current understanding is limited, as it considers BPSD as a homogenous construct. This fails to account for their heterogeneity and hinders development of interventions that address the underlying causes of the target BPSD subsyndromes. Moreover, understanding the influence of proximal factors-circadian rhythm-related factors (ie, sleep and activity levels) and physical and psychosocial unmet needs states-on BPSD subsyndromes is limited, due to the challenges of obtaining objective and/or continuous time-varying measures.ObjectiveThe aim of this study was to explore factors associated with BPSD subsyndromes among community-dwelling older adults with dementia, considering sets of background and proximal factors (ie, actigraphy-measured sleep and physical activity levels and diary-based caregiver-perceived symptom triggers), guided by the need-driven dementia-compromised behavior model.MethodsA prospective observational study design was employed. Study participants included 145 older adults with dementia living at home. The mean age at baseline was 81.2 (SD 6.01) years and the sample consisted of 86 (59.3%) women. BPSD were measured with a BPSD diary kept by caregivers and were categorized into seven subsyndromes. Independent variables consisted of background characteristics and proximal factors (ie, sleep and physical activity levels measured using actigraphy and caregiver-reported contributing factors assessed using a BPSD diary). Generalized linear mixed models (GLMMs) were used to examine the factors that predicted the occurrence of BPSD subsyndromes. We compared the models based on the Akaike information criterion, the Bayesian information criterion, and likelihood ratio testing.ResultsCompared to the GLMMs with only background factors, the addition of actigraphy and diary-based data improved model fit for every BPSD subsyndrome. The number of hours of nighttime sleep was a predictor of the next day's sleep and nighttime behaviors (odds ratio [OR] 0.9, 95% CI 0.8-1.0; P=.005), and the amount of energy expenditure was a predictor for euphoria or elation (OR 0.02, 95% CI 0.0-0.5; P=.02). All subsyndromes, except for euphoria or elation, were significantly associated with hunger or thirst and urination or bowel movements, and all BPSD subsyndromes showed an association with environmental change. Age, marital status, premorbid personality, and taking sedatives were predictors of specific BPSD subsyndromes.ConclusionsBPSD are clinically heterogeneous, and their occurrence can be predicted by different contributing factors. Our results for various BPSD suggest a critical window for timely intervention and care planning. Findings from this study will help devise symptom-targeted and individualized interventions to prevent and manage BPSD and facilitate personalized dementia care.

Project description:Background: Identifying the characteristics of behavioral and psychological symptoms of dementia (BPSD) associated with different dementia types may be a promising strategy to effectively deal with BPSD. We aimed to synthesize the prevalence rates of BPSD characteristics in community-dwelling dementia patients. Methods: We searched Medline, EMBASE, and PsycARTICLES databases for original clinical studies published until December 2020 that enrolled at least 300 community-dwelling dementia patients. The methodological qualities of prevalence studies were assessed using the Joanna Briggs Institute's critical appraisal checklist. Results: Thirty studies were included. The prevalence of the BPSD characteristic ranged from 4 (elation and mania) to 32% (apathy) in the pooled samples. The prevalence of delusions, anxiety, apathy, irritability, elation and mania, and aberrant motor behavior in Alzheimer's disease patients was 1.72-2.88 times greater than that in vascular dementia (VD) patients, while the prevalence of disinhibition in VD patients was 1.38 times greater. The prevalence of anxiety, irritability, and agitation and aggression, delusion, hallucinations, apathy, disinhibition, and aberrant motor behavior tended to increase as the severity of dementia increased, while that of depression, eating disorder, sleep disorders, and elation and mania tended to stable. In community-dwelling patients with dementia, the pooled prevalence of apathy, depression, anxiety, irritability, agitation and aggression, sleep disorders, and eating disorder was higher than 20%, while that of disinhibition and elation and mania was lower than 10%. Conclusion: Overall, the pooled prevalence of apathy, depression, anxiety, irritability, agitation and aggression, sleep disorders, and eating disorder was generally high in patients with dementia. Also, the prevalence of some BPSD characteristics differed according to the type and the severity of dementia. The methodological quality of the included studies is not the best, and high heterogeneity may affect the certainty of the findings. However, the results of this review can deepen our understanding of the prevalence of BPSD. Systematic Review Registration: https://osf.io/dmj7k, identifier: 10.17605/OSF.IO/DMJ7K.

Project description:BackgroundBehavioral and psychological symptoms of dementia (BPSD) are present in a majority of patients with dementia contributing to increased morbidity, health care costs, and caregiver burden. While there are no United States Food and Drug Administration (FDA)-approved medications for these symptoms, off-label use of medications such as antipsychotics have been shown to have significant adverse effects including increased mortality. The goal of this review is to examine the efficacy and safety of anticonvulsants in the treatment of BPSD.MethodsWe will systematically search for randomized trials of anticonvulsants compared to placebo or other treatments such as antidepressants and antipsychotics from the following sources: The Cochrane Library, MEDLINE (OVID SP) in Process and Other Non-Indexed Citations (latest version), EMBASE, clinicalTrials.gov , and the WHO Clinical Trials Registry. The studies will be limited to those published in English but the study location can be worldwide. We will include studies pertaining to individuals with dementia and symptoms of BPSD. The primary outcomes will be behavioral change as measured by validated scales and secondary outcomes will include caregiver burden, quality of life, placement in long term care facility, serious adverse effects, and treatment discontinuation due to adverse effects. Two sets of reviewers will independently screen select and extract data. We will narratively describe the major findings and conclusions from individual studies. Patients who are prescribed antiepileptic drugs (AEDs) for other indications, including seizures, will be excluded. Outcomes of interest will include a change in a validated scale that measures BPSD, serious adverse events, and caregiver quality of life outcomes. If the data are found to be appropriate for a meta-analysis, we will use a random effects model to compute summary estimates of treatment effects.DiscussionThis is a protocol for a systematic review addressing the anticonvulsant group of medications as a whole, and as such, our results will inform current clinical practice in the use of anticonvulsants for BPSD. It will also help clinicians and policy makers compare the efficacy of anticonvulsants compared to antidepressants and antipsychotics as well as identify areas which will need further study.Systematic review registrationPROSPERO CRD42017079826.

Project description:BackgroundDementia is a major mental health problem worldwide, and an optimal anti-dementia drug that could modify its core symptoms has not been developed yet. Behavioral and psychological symptoms of dementia (BPSD), an important clinical manifestation of dementia, is closely related to disease burden, caregiver burden, and consequent social burden. In general, many experts and international guidelines prefer non-pharmacological interventions, including psychosocial intervention, and complementary and integrative medicine in the management of BPSD. However, in clinical settings, psychotropic drugs are frequently used; therefore, the need to establish and actively use effective non-pharmacological interventions is emphasized. Therefore, in this systematic review, we will evaluate the effectiveness and safety of acupuncture, a promising non-pharmacological complementary and integrative medicine, for BPSD.Methods and analysisA comprehensive search will be conducted in 13 electronic medical databases. Regardless of its design, original clinical studies, such as randomized controlled clinical trials, nonrandomized controlled clinical trials, and before-after studies, will be included to assess the beneficial effects and safety of acupuncture on BPSD. The severity of BPSD symptoms assessed by the validated tool will be considered as a primary outcome. The secondary outcome included the total effective rate, daily living activities and quality of life of patients, burden and quality of life of caregiver, placement in a long-term care facility from home, and safety data. The study selection, data extraction, and quality assessment process were performed by 2 independent researchers. The methodological quality of the included studies will be assessed using validated tools according to its design, such as the Cochrane Collaboration's risk of bias tool. RevMan version 5.3 will be used to perform the meta-analysis, with mean differences for continuous outcomes and risk ratio for binary outcomes, and 95% confidence intervals. A fixed- or random-effects model will be used according to the heterogeneity and number of included studies.Ethics and disseminationAs this protocol is for a systematic review, ethical approval is not required. The results of the systematic review will be disseminated by the publication of a manuscript in a peer-reviewed journal or presentation at a relevant conference.Registration numberOSF (URL: https://osf.io/hu5ac), PROSPERO (CRD42020211005) (URL: https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42020211005).

Project description:Background: Behavioral and psychological symptoms of dementia (BPSD, also known as neuropsychiatric symptoms (NPS), changed behaviors and responsive behaviors), occur in up to 90 percent of people living with dementia (PLWD). These symptoms and behaviors strongly correlate with functional and cognitive impairment and contribute to ~30% of overall dementia costs. As decisions regarding care and strategies for BPSD are generally based on professional frames of reference, this study investigates whether the perspectives of PLWD and families/care partner on BPSD terminology can inform a more nuanced conceptualization of BPSD. Methods: PLWD and families/care partners participated in one-on-one semi-structured interviews. A thematic iterative approach was used to code the data and identify common themes until theoretical saturation was reached. Themes were compared between groups. Data were analyzed deductively in relation to pre-existing terminology regarding BPSD, and inductively to discover new ideas on use of such terminology as perceived by PLWD and others. Results: Forty-one volunteers were interviewed: 21 PLWD, mean age 71 yrs, mean Mini-Mental State Examination score 25, and 20 family members/care partners. Three main themes emerged from the data: (1) descriptions of BPSD from people with lived experience compared to clinical terms, (2) viewpoints on interpreting causes, and (3) experiences of concurrent BPSD. The experiences described and terms used by PLWD and families/care partners differed from terms used in existing professional frameworks (e.g., "disinhibition" described as 'loss of filter') and there were differences between PLWD and family members' interpretations of BPSD causes. Discussion/Conclusion: Reports from PLWD and families/carers describing their experiences of BPSD suggest a reconceptualization of BPSD terminology is needed to understand and de-stigmatize these symptoms and behaviors. For example, the term "agitated/hard to handle" would benefit by clearer, contextualized description, such as "frustrated with cognitive decline, discriminatory behavior and inadequate support systems." In better understanding individual expressions of BPSD, families, professionals and societies will be able to respond in ways that are helpful for PLWD. An informed, integrated understanding of BPSD and improved terminology use will have the potential to improve the quality of care and support for PLWD.

Project description:BackgroundHigh-quality clinical practice guidelines (CPGs) are important for the effective treatment of behavioral and psychological symptoms of dementia (BPSD). However, recommendations provided by different quality guidelines may lead to varied clinical practice outcomes.ObjectiveTo assess the quality of available CPGs for the management of BPSD and summarize the best recommendations for treating BPSD.MethodsThis was a systematic review of CPGs for the management of BPSD with data obtained from electronic databases and evaluated using the Appraisal of Guidelines for Research and Evaluation II instrument, consisting of six domains: "Scope and purpose", "Stakeholder involvement", "Rigor of development", "Clarity of presentation", "Applicability", and "Editorial independence". The criteria for high-quality guidelines were set as: the score of high-quality guidelines in the "Rigor of development" domain should be ≥60% and as well as a score of >60% in at least three other domains. High-quality guidelines were selected for recommendation extraction, and the final recommendations were formed in combination with the latest meta-analysis and randomized clinical-trial results.ResultsIn term of median scores in each domain for the six included CPGs, "Scope and purpose" (87.5%) scored better than all others, whereas "Applicability" (46.5%) was the domain with the lowest score. Four CPGs (2015 APA, 2018 NICE, 2018 CANADA, 2020 EAN) met the criteria of high-quality guidelines and were used to extract recommendations. From these four CPGs, nine specific recommendations related to the management of BPSD were summarized, of which seven were related to pharmacological treatment and two to non-pharmacological treatment. These recommendations covered the applicability of antipsychotic drugs, medication recommendations, withdrawal times, and several suitable non-pharmacological therapies.ConclusionThe quality of CPGs for the management of BPSD requires improvement, especially for the "Applicability" domain. For psychotic-like symptoms in dementia, the use of antipsychotics should be based on the individual's risk-benefit ratio, and the use of atypical antipsychotics seems to be a better choice. Non-pharmacological treatments may be suitable for emotional symptoms and sleep disorders.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42020209204.
