Role of antipsychotics for treating behavioral and psychological symptoms of dementia

Over the past three decades, concerns about the high prevalence of antipsychotic use in the nursing homes （NHs） for the management of behavioral and psychological symptoms of dementia continue to be emphasized and intervened by many. However, despite the numerous side effects and the recent blackbox warning by the United States Food and Drug Administration about the increased risks for stroke and sudden death associated with the use of antipsychotics in dementia, the preva-lence of antipsychotic use in NHs remains high. While the use of antipsychotics appeared to have modest effcacy in reducing symptoms of aggression and psychosis in dementia, there is insuffcient evidence to routinely rec-ommend the use of alternative psychopharmacological treatments for these symptoms. Hence, clinicians have to balance the safety warnings against the need to treat these symptoms in order to prevent harm to the resident that may result from his/her dangerous behaviors. Although the use of antipsychotics may be warranted in some cases, organizational, resource and training support should be provided to encourage and equip NH staff to participate in interventions so as to minimize inappropriate use of these medicines in NHs. This review will discuss the place in therapy, the trend and appropriateness of antipsychotic use in NHs, as well as the effectiveness of current and future strategies for reducing antipsychotic use in the NHs.

The Efficacy and Safety of Yokukansankachimpihange for Treating Behavioral and Psychological Symptoms of Dementia in Patients with Alzheimer’s Disease: An Open-Label Pilot Study

Previous clinical trials have demonstrated the efficacy of yokukansan, a traditional Japanese medicine, for the treatment of behavioral and psychological symptoms of dementia (BPSD). However, less evidence is available for the treatment of BPSD with yokukansankachimpihange (YKSCH), which consists of yokukansan and two additional herbal ingredients. The present study was conducted to investigate the efficacy and safety of YKSCH for treating BPSD in patients with Alzheimer’s disease (AD). We enrolled outpatients with mild-to-moderate AD who exhibited BPSD and obtained a Neuropsychiatric Inventory (NPI) score of >3 including subscale scores for “agitation”, “anxiety”, “irritability”, and “sleep and night-time behavior change”. A daily YKSCH dose of 7.5 g was administered for 12 weeks with concomitant administration of anti-dementia medication. BPSD was evaluated using the NPI at baseline and every 4 weeks during the intervention. We also examined apathy using the Japanese translation of the Apathy Scale, the short version of the Japanese version of the Zarit Caregiver Burden Interview, and the Modified Crichton Rating Scale for Predicting Activities of Daily Living. Cognitive dysfunction was evaluated using the Mini Mental State Examination and the AD Assessment Scale-Cognitive (Japanese version). Five participants were enrolled. The NPI total score tended to decrease between the baseline and 8-week evaluations during the YKSCH intervention (Wilcoxon signed rank test, P = 0.063). In terms of the NPI subscale scores, “apathy”, “agitation”, “delusions”, and “sleep and night-time behavior change” decreased after the intervention in those who exhibited each symptom at baseline. There were no significant differences in the other scores examined. No serious adverse events were observed. YKSCH could ameliorate BPSD in patients with mild-to-moderate AD with agitation, anxiety, irritability, and sleep and night-time behavior change, and it was well-tolerated.

Gabapentin for the treatment of behavioral and psychological symptoms of dementia

Objective: To examine the efficacy of gabapentin for the treatment of behavioral and psychological symptoms of dementia (BPSD). Design: A retrospective chart review. Settings: Tertiary care geriatric psychiatry inpatient unit. Participants: 230 patients with BPSD. Measurements: The socio-demographic information, type of behaviors, co-morbid psychiatric and medical diagnoses, daily doses of medications and side-effects were recorded. Results: Of the 230 patients, 22 were treated with gabapentin. Twenty of these patients were on a combination of gabapentin and an antipsychotic medication while two patients were treated with gabapentin monotherapy. Eighteen of the 20 patients in the combination group tolerated the treatments with little or no side effects as did the two patients in the monotherapy group. Conclusions: Gabapentin may be a safe option for the treatment of BPSD in combination with antipsychotic medications. Gabapentin may also be effective as monotherapy in certain patients with BPSD.

Improving the Appropriateness of Antipsychotic Prescribing for Behavioral and Psychological Symptoms of Dementia (BPSD): A Pilot Study of the Psychotropic Use Monitoring (PUM) Program

In nursing homes, antipsychotic prescribing decisions (APDs) for managing behavioral and psychological symptoms of dementia (BPSD) depend on the nursing staff’s feedback. Inappropriate APDs can result in the lack of timeliness, objectivity and important clinical information when nursing staff’s feedback on residents’ behavior and pharmacotherapy outcomes. Currently, there are no reported interventions for improving psychiatrists’ APDs through nursing staff’s monitoring and feedback processes. This one-group pre-and-post pilot study aimed to evaluate the feasibility and impact of implementing a newly-developed Psychotropic Use Monitoring (PUM) program for improving the appropriateness of APDs in a 50-bed dementia ward of a nursing home. The PUM intervention involved 16 pharmacist-trained nursing staff, who monitored and reported residents’ BPSD changes and psychotropic side effects for 24 weeks, while carrying out their routine care duties. A face-to-face interview was then administered to determine the nursing staff’s perceptions of PUM. Data of 51 residents were collected from hardcopy individual patient records to evaluate the changes in APDs and the number of resident falls before and after implementing PUM. The nursing staff reported increases in their knowledge, awareness, confidence, and actual frequency of monitoring for side effects, as well as their ability in differentiating and managing BPSD (p < 0.05). After PUM, there was a significant increase in the number of APDs due to side effect-related reasons (4 versus 16) (p < 0.031). Although not significant, the number of APDs with no documented reasons (5 versus 9) and the number of resident falls (7 versus 15) appeared to be lesser after PUM. This study demonstrated the nursing staff’s positive participation in PUM intervention, specifically in monitoring and feedback of side effects. Furthermore, a potential exists for PUM to encourage more judicious APDs, which may be useful in settings with heavy patient load, limited human resources and dependence on foreign nursing staff from differing cultural backgrounds.

Quantitative evaluation of severity of behavioral and psychological symptoms of dementia in patients with vascular dementia

To quantitatively evaluate severity of behavioral and psychological symptoms of dementia(BPSD)for vascular dementia(VD).Changes of 51 patients with VD in BPSD between the first and 24th week were assessed using the Neuropsychiatric Inventory(NPI)and the behavioral pathology in Alzheimer’s disease(BEHAVE-AD)rating scale,in detrended fluctuation analysis(DFA)represented by diurnal activity(DA),evening activity(EA),and nocturnal activity(NA),and the relationships were analyzed.The subscores of activity disturbances,diurnal rhythm disturbances,and anxieties and phobias in the BEHAVE-AD score,and that of agitation,irritability,and sleep disorder in the NPI score were significantly increased compared with the first week,as was for the changes for EA in the DFA value.A linear correlation was observed between the changes of activity disturbances plus anxieties and phobias,and those of DA,and between the development of diurnal rhythm and those of EA,the vehement and autism scores and those of DA,and the difference in sleep disorder scores and those of EA,respectively.Analysis of DA,NA,and EA may reflect the fluctuational degrees of VD-BPSD,can provide a useful assessment of VD-BPSD accompanied by clinical scores for VD.

An association between the location of white matter changes and the behavioral and psychological symptoms of dementia in Alzheimer's disease patients

Objective:The frontal lobe may be involved in circuits associated with depression,apathy,aggression,and other psychiatric symptoms.Although white matter changes(WMC)are related to the severity of behavioral and psychological symptoms of dementia(BPSD)in patients with Alzheimer’s disease(AD),it is unclear which part of the WMC may play the most important role in BPSD.This study was designed to investigate the relationship between the location of WMC and the severity of BPSD in AD patients.Methods:Among patients diagnosed with Alzheimer’s disease between 2009 and2014,387 patients were retrospectively reviewed after those with pre‐existing organic brain syndrome,psychiatric diseases,or toxic‐metabolic encephalopathy were excluded.Patients’demographic and laboratory data,WMC measured with brain computed tomography and scored using the age‐related white matter changes(ARWMC)scale,and neuropsychological tests,including the cognitive abilities screening instrument(CASI),the Mini‐Mental State Examination(MMSE),the clinical dementia rating scale with sum‐box(CDR‐SB),and the neuropsychiatric inventory(NPI)were analyzed.Results:There was no significant difference in the NPI between patients with and without a history of stroke,hypertension,and diabetes.No significant difference in the NPI was identified between different sexes or different Apolipoprotein E(APOE)alleles.The NPI score was significantly correlated with the duration of education(r=–0.4515,P=0.0172),CASI(r=–0.2915,P<0.0001),MMSE(r=–0.8476,P<0.0001),and CDR‐SB(r=2.2839,P<0.0001).WMC in the right frontal lobe showed a significant difference in NPI in comparison to those without WMC(P=0.0255).After adjusting for age,duration of education,and CASI,WMC in the right frontal lobe remained significantly associated with the NPI score(β=3.8934,P=0.042).Conclusions:WMC involving the right frontal lobe may play an important role in the BPSD in AD patients during their dementia diagnosis.Further studies are necessary to confirm whether controlling the risk factors of WMC can slow the progression of BPSD.

Rehabilitative Outcomes after Hip Fracture in a Special Care Unit for Persons with Dementia and Behavioral and Psychotic Symptoms

Aim: Hip fracture implies severe problems to older people;special concerns regard persons with dementia, due either to cognitive impairment, or to behavioral and psychic symptoms. This study illustrates rehabilitative outcomes of these patients discharged by a special care unit ruled by “GentleCare” principles. Method: 54 patients [89% females, aged 82.3 years (range 66 - 94)] followed a post-surgery rehabilitative program carried out by a physiotherapist and an occupational therapist, supported by a psychologist. The multidimensional assessment consisted of cognition evaluation (Mini Mental State Examination, Clinical Dementia Rating, Global Deterioration Scale), functional evaluation (Barthel Index, Tinetti Gait and Balance, Bedford Alzheimer Nursing Severity scale), behavioral evaluation (UCLA Neuropsychiatric Inventory) and comorbidity evaluation (Cumulative Illness Rating Scale). Results: All parameters improved, including the 5 most frequent behavioral and psychic symptoms that usually preclude admission in ordinary rehabilitation units. 24% of improvement in Barthel Index total score was explained by agitation and apathy at discharge, in a multiple linear regression model: better functional levels corresponded to smoother behavioral problems. Most patients improved;70.5% of them were discharged to home. Conclusion: A prosthetic approach enables valuable results in the rehabilitation of severely demented patients with hip fracture also in presence of behavioral symptoms.

Development and validation of a nutrition-related genetic-clinical-radiological nomogram associated with behavioral and psychological symptoms in Alzheimer’s disease

Background:Few evidence is available in the early prediction models of behavioral and psychological symptoms of dementia(BPSD)in Alzheimer’s disease(AD).This study aimed to develop and validate a novel genetic-clinical-radiological nomogram for evaluating BPSD in patients with AD and explore its underlying nutritional mechanism.Methods:This retrospective study included 165 patients with AD from the Chinese Imaging,Biomarkers,and Lifestyle(CIBL)cohort between June 1,2021,and March 31,2022.Data on demographics,neuropsychological assessments,single-nucleotide polymorphisms of AD risk genes,and regional brain volumes were collected.A multivariate logistic regression model identified BPSD-associated factors,for subsequently constructing a diagnostic nomogram.This nomogram was internally validated through 1000-bootstrap resampling and externally validated using a time-series split based on the CIBL cohort data between June 1,2022,and February 1,2023.Area under receiver operating characteristic(ROC)curves,calibration curves,and decision curve analysis(DCA)were used to assess the discrimination,calibration,and clinical applicability of the nomogram.Results:Factors independently associated with BPSD were:CETP rs1800775(odds ratio[OR]=4.137,95%confidence interval[CI]:1.276-13.415,P=0.018),decreased Mini Nutritional Assessment score(OR=0.187,95%CI:0.086-0.405,P<0.001),increased caregiver burden inventory score(OR=8.993,95%CI:3.830-21.119,P<0.001),and decreased brain stem volume(OR=0.006,95%CI:0.001-0.191,P=0.004).These variables were incorporated into the nomogram.The area under the ROC curve was 0.925(95%CI:0.884-0.967,P<0.001)in the internal validation and 0.791(95%CI:0.686-0.895,P<0.001)in the external validation.The calibration plots showed favorable consistency between the prediction of nomogram and actual observations,and the DCA showed that the model was clinically useful in both validations.Conclusion:A novel nomogram was established and validated based on lipid metabolism-related genes,nutritional status,and brain stem volumes,which may allow patients with AD to benefit from early triage and more intensive monitoring of BPSD.Registration:Chictr.org.cn,ChiCTR2100049131.

Predictors of Comorbid Psychological Symptoms among Patients with Social Anxiety Disorder after Cognitive-Behavioral Therapy

Aim: The present study aimed to examine the predictors of comorbid psychological symptoms in social anxiety disorder (SAD) after cognitive-behavioral therapy (CBT). Methods: One hundred fourteen SAD patients completed manualized group CBT. We examined associations between the personality dimensions of NEO Five Factor Index (NEO-FFI) and the subscales of Symptom Checklist-90 Revised (SCL-90-R) in SAD patients after CBT using multiple regression analysis. Results: High levels of conscientiousness at baseline predicted symptom reduction on 4 SCL-90-R scales, including somatization, obsessive-compulsive, anxiety and global severity index in patients with SAD after CBT. And high levels of agreeableness predicted symptom reduction on 2 SCL-90-R scales, including Hostility and Paranoid Ideation. High levels of openness predicted psychoticism. Conclusion: The present study suggested that high levels of three NEO-FFI dimensions (openness, agreeableness, conscientiousness) might predict comorbid psychological symptoms reduction in SAD patients after CBT. For the purpose of improving comorbid psychological symptoms with SAD patients, it might be useful to pay more attention to these dimensions of NEO-FFI at baseline.

Characteristics of Patients with Decreased Cognitive Function Undergoing Treatment for Acute Exacerbation of Chronic Heart Failure—Basic Survey for Standardization of Nursing to Prevent Discontinuation of Treatment

The purpose of this study is to clarify the characteristics of patients with decreased cognitive function undergoing treatment for acute exacerbation phase of chronic heart failure as a basic survey with a view to the standardization of nursing to prevent discontinuation of treatment of patients with declining cognitive function in the acute exacerbation phase of chronic heart failure. As the first stage of the research, using the interview guide created based on the background of discontinuation of treatment and symptomatic monitoring from 33 target literature sources, seven certified chronic heart failure nurses and 15 certified dementia nurses were given semi-structured interviews. Data obtained from the interviews was analyzed by qualitative induction. As a result, we obtained opinions/views on 8 situations namely, “cognitive function at hospitalization”, “characteristics at hospitalization, “characteristics when receiving examinations, procedures or treatment”, “characteristics of course of treatment”, “characteristics related to difficulties in grasping the symptoms of chronic heart failure and indices of deterioration”, “characteristics when using diuretics”, “characteristics concerning compliance with dietary restrictions” and “support required for discharge from hospital” concerning patients with declining cognitive function. In the future, it is necessary to prepare nursing protocols incorporating these contents for standardization of nursing.

Evidence for using dextromethorphan-quinidine for the treatment of agitation in dementia

Behavioral and psychological symptoms including agitation are common in dementia,and are associated with decreased quality of life,increased risk of institutionalization,and greater patient and caregiver distress.Pharmacological agents used for management of behavioral and psychological symptoms of dementia are limited by their tolerability,prompting a need for identifying efficacious and safe pharmacological treatments for managing agitation in dementia.The combination of dextromethorphan and quinidine sulfate is approved for pseudobulbar affect,and may be effective in managing agitation in dementia.A review of literature found only one randomized controlled trial that evaluated the use of dextromethorphan-quinidine for the management of agitation in dementia when compared to placebo.Data from this trial demonstrated that dextromethorphan-quinidine decreased agitation in dementia,and was well tolerated.Although promising,further research is needed before dextromethorphan-quinidine combination can be accepted as a standard treatment for agitation in dementia.
