Evaluating the Clinical Impact of National Dementia Behaviour Support Programs on Neuropsychiatric Outcomes in Australia

The Specialist Dementia Care Program in Australia: Evidence to date on a home-like model of care for people with very severe behaviours and psychological symptoms of dementia

OBJECTIVES

Behaviours and psychological symptoms of dementia (BPSD) have a serious impact on care and health outcomes, such as inappropriate pharmacotherapy and impaired quality of life. These symptoms are common across care settings but are more prevalent in residential aged care homes (RACHs). BPSD such as aggression and psychosis may pose a high risk of harm to residents, co-residents, caregivers and families, and the severe forms of these BPSD are linked to RACH premature admission. When people with very severe BPSD in Australia cannot be cared for in mainstream RACHs, the Specialist Dementia Care Program (SDCP) is offered. This article describes the SDCP model of care and examines the available evidence on SDCP outcomes.

METHODS

The SDCP model of care delivers person-centred care via multidisciplinary staff in small, 'cottage-like', domestic units with a familiar, dementia-friendly care environment for an anticipated duration of 12  months. SDCP units are designed to stabilise or reduce BPSD, facilitate transition to mainstream RACHs, prevent unnecessary hospitalisations and minimise health-care costs.

RESULTS

Preliminary evidence suggests that SDCP units may enhance resident outcomes, decrease the severity of BPSD and improve quality of life.

CONCLUSION

This article highlights the importance of prioritising the type of care this program provides to people with very severe BPSD.

Palliative Care for People With Very Severe to Extreme Behavioural and Psychological Symptoms of Dementia (BPSD): A Scoping Review

AIM

To explore current evidence regarding the provision of palliative care for individuals with very severe to extreme behavioural and psychological symptoms of dementia (BPSD) in a hospital setting.

DESIGN

Scoping review.

REPORTING METHOD

The PRISMA-ScR reporting guideline.

METHODS

The JBI guidelines for scoping reviews were followed. A data extraction form assisted in the identification of key findings via a process of content analysis.

DATA SOURCES

Studies were obtained from bibliographic databases of PubMed, CINAHL, and PsycINFO.

RESULTS

This review included six articles, and nine categories emerged from the findings. Symptom assessment and management, pain assessment challenges, atypical presentation of end-stage dementia, complex prescribing and treatment practices, principles of person-centred care, collaboration; training for health care professionals; emotional impact on staff; and family and caregivers.

CONCLUSIONS

This scoping review highlighted a significant gap in the literature regarding palliative care for people living with very severe to extreme BPSD in hospital settings. This review highlighted key differences in the presentation of people with BPSD needing palliative care. There is a need for tailored models of care, specialised training and education for health professionals, families, and carers, and recognition of dementia as a terminal illness.

IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE

The results of this review provide valuable insights into the level of understanding about the unique palliative care needs for people experiencing very severe to extreme BPSD, making an important contribution to the planning and development of future models of care.

IMPACT

Mapping the available literature highlights a paucity of research in palliative care for people with very severe to extreme BPSD in hospital settings. There is a need for rigorous research studies and models of care developed and informed by the evidence for this small population necessitating unique care needs.

Psychotropic Polypharmacy in Dementia: A Retrospective Analysis for People with Neuropsychiatric Symptoms Referred to an Australian Dementia Support Service

BACKGROUND AND OBJECTIVES

Despite their limited benefits and serious adverse effects, psychotropics remain frequently prescribed for neuropsychiatric symptoms (NPS) of dementia. Psychotropic polypharmacy, the use of two or more concomitant psychotropic medications, is therefore not recommended for people with dementia. The objectives of this study were to investigate the prevalence of psychotropic polypharmacy in Australians living with dementia whose caregivers sought external NPS support from Dementia Support Australia (DSA; the national provider of NPS support) and the association of psychotropic polypharmacy with their demographics and NPS characteristics.

METHODS

A retrospective cross-sectional study of a subset of DSA referrals at baseline (i.e., yet to receive psychosocial intervention(s)) between 2016 and 2020 was conducted. Referrals with and without psychotropic polypharmacy were compared on the basis of demographic characteristics (e.g., sex, dementia subtype), NPS type (e.g., agitation), NPS severity and associated caregiver distress as measured by the Neuropsychiatric Inventory (NPI), using Pearson's chi-square test and Welch's t-test for categorical and continuous data, respectively. Logistic regression models were used to examine the relationship between individual NPI domains and exposure to psychotropic polypharmacy.

RESULTS

A total of 421 referrals (mean age 81.5 (standard deviation 8.5) years, 52.3% males, 46.8% Alzheimer's disease) were analysed. Of those, over 90% (n = 383) were prescribed at least one psychotropic, with 214 referrals (50.8%) prescribed psychotropic polypharmacy. The medication types most associated with psychotropic polypharmacy were antipsychotics (n = 162, 75.7%), opioids (n = 104, 48.6%), anxiolytics (n = 93, 43.5%), sedative/hypnotics (n = 52, 24.3%) and antidepressants (n = 47, 22.0%). No relationship between psychotropic polypharmacy and any variable tested was identified, including age, sex, dementia subtype and NPI severity.

CONCLUSIONS

Psychotropic polypharmacy is highly prevalent in Australians living with dementia referred to external dementia-specific behaviour support programs, but no factors were associated with its presence in this cohort.

The Impact of Nursing Home Culture Change: An Integrative Review

OBJECTIVES

The Nursing Home Culture Change (NHCC) movement promotes a person- and relationship-centered approach and a small-scale, homelike model for NHs. The present study aimed to integrate the most recent empirical findings regarding the impact of NHCC on resident, staff, family, and organizational outcomes.

DESIGN

Integrative review.

SETTING AND PARTICIPANTS

Not applicable.

METHODS

OVID MEDLINE, PsycINFO, Embase, and CINAHL databases were searched for quantitative or mixed studies published in English between 2018 and 2022 and examining the effect of NHCC on resident, staff, family, and/or organizational outcomes. A narrative and tabular synthesis of the results is provided.

RESULTS

A total of 1687 references were identified. Following duplicate removal, title and abstract screening, and full-text screening, 75 studies were retained for synthesis and suggest a positive impact of NHCC on resident (eg, quality of life and neuropsychiatric function), staff (eg, job satisfaction and stress), family (eg, satisfaction and depressive symptoms), and organizational (eg, NH attractiveness and occupancy rate) outcomes.

CONCLUSIONS AND IMPLICATIONS

NHCC shows promising results in all studied outcome categories. Future research should further investigate obstacles to NHCC implementation, conduct cost-benefit analyses supported by appropriate statistical tests, and define ways to improve NH staff education as well as NH policies and regulations to better support NHCC initiatives.

Behaviours and psychological symptoms of childhood dementia: two cases of psychosocial interventions

Childhood dementias are a group of rare, fatal neurodegenerative disorders, characterised by global cognitive decline, loss of previously acquired developmental skills and behaviours and psychological symptoms of dementia (BPSD). Batten disease, or neuronal ceroid lipofuscinosis, and Sanfilippo syndrome, or mucopolysaccharidosis type III, are two of the more common forms of childhood dementia disorders worldwide. While psychosocial interventions are the best available therapeutic approach for BPSD management in adult-onset dementia, there is very limited literature or clinical experience in the context of childhood dementia. To address this gap, we conducted a descriptive case analysis of BPSD profiles, associated contributing factors and targeted psychosocial interventions in two cases with childhood dementia disorders (Sanfilippo syndrome and CLN3 (juvenile onset) Batten disease) who were referred to Dementia Support Australia, a national dementia behaviour support service in Australia. Primary BPSD identified in these disorders included physical and verbal aggression and irritability/lability. In these cases, contributing factors to the development of BPSD were not monolithic, encompassing pain, caregiver's approach and over or under-stimulation. Improvement in BPSD were observed using the Neuropsychiatric Inventory-Quesionnaire and globally noted as per the qualitative feedback reported by family and caregivers. Person-centred, multimodal psychosocial interventions were recognised as effective therapies in resolving BPSD in these cases. In conclusion, the case studies described the nature and presentation of BPSD in two common forms of childhood dementia and demonstrated the potential benefits of person-centred psychosocial interventions (delivered through national dementia-specific support programs) in alleviating BPSD such as irritability and aggression in these disorders.

Referral reasons to a Victorian mental health triage service for individuals living with young-onset dementia

Objectives Mental health triage services are the first contact for people wanting support for their mental health and provide access to public mental health services in Victoria, Australia. People living with young-onset dementia and their families may contact triage services seeking assistance for behaviour changes and pathways to care as there are few alternative services available. Methods The authors reviewed the minimum triage dataset from one of the largest mental health services in Victoria, Australia from 2018 to 2021 investigating reasons for referral for people with young-onset dementia. Results Of the 1766 referrals for 'dementia', 145 were for young-onset dementia. Of these, 69% were referred for behaviour changes. About half of the referrals for behaviour changes were triaged as 'advice only'. One-third of referrals were from general practitioners. Conclusions The availability of dementia-specific support services that could provide advice on dementia as well as advice for behaviour changes related to the disease could potentially ease the burden of phone calls received by mental health triage services.

Pain prevalence, intensity, and association with neuropsychiatric symptoms of dementia in immigrant and non-immigrant aged care residents in Australia

Pain recognition for culturally diverse people is complex as pain experience is subjective and influenced by cultural background. We compared the prevalence, intensity, and association of pain with neuropsychiatric symptoms (NPS) between immigrants and non-immigrants living with dementia in residential aged care homes (RACHs) who were referred to two Dementia Support Australia programs. Immigrant status was defined by the documented country of birth. Pain and NPS were assessed using PainChek® and the Neuropsychiatric Inventory, respectively. Subgroup analyses were also completed for English-speaking and non-English-speaking immigrants. A total of 17,637 referrals [immigrants, n = 6340; non-immigrants, n = 11,297] from 2792 RACHs were included. There were no significant differences for the prevalence of pain across all groups. Immigrants were slightly more likely to have moderate pain or severe pain than non-immigrants. Non-English-speaking immigrants had 0.5 points higher total pain scores on average (Cohen's d = 0.10 [0.05, 0.15], p < 0.001) than non-immigrants. Total pain score had a significant effect on total NPS severity scores in all groups. While pain prevalence is similar across groups, higher pain intensities are more common among immigrants living with dementia. Increased care staff awareness, education, and training about the potential effect of culture on pain expression is needed.

Developing an ontology of non-pharmacological treatment for emotional and mood disturbances in dementia

Emotional and mood disturbances are common in people with dementia. Non-pharmacological interventions are beneficial for managing these disturbances. However, effectively applying these interventions, particularly in the person-centred approach, is a complex and knowledge-intensive task. Healthcare professionals need the assistance of tools to obtain all relevant information that is often buried in a vast amount of clinical data to form a holistic understanding of the person for successfully applying non-pharmacological interventions. A machine-readable knowledge model, e.g., ontology, can codify the research evidence to underpin these tools. For the first time, this study aims to develop an ontology entitled Dementia-Related Emotional And Mood Disturbance Non-Pharmacological Treatment Ontology (DREAMDNPTO). DREAMDNPTO consists of 1258 unique classes (concepts) and 70 object properties that represent relationships between these classes. It meets the requirements and quality standards for biomedical ontology. As DREAMDNPTO provides a computerisable semantic representation of knowledge specific to non-pharmacological treatment for emotional and mood disturbances in dementia, it will facilitate the application of machine learning to this particular and important health domain of emotional and mood disturbance management for people with dementia.

Neuropsychiatric symptoms of dementia in those with and without a recorded history of psychological trauma: A comparative study from an Australian dementia support service

OBJECTIVE

To compare the number and severity of neuropsychiatric symptoms (NPS) and associated caregiver distress between those with and without a noted history of psychological trauma among those referred to a specialised national dementia NPS support service.

METHODS

This was a 5-year retrospective observational study of records from the Dementia Support Australia NPS support service. NPS were reported by formal or informal caregivers at service entry using the Neuropsychiatric Inventory Nursing Home version or Questionnaire version. A history of psychological trauma was recorded in the person's social or medical history and/or endorsed as a contributor to NPS by a trained dementia consultant after a comprehensive clinical review. Regression was used to examine the impact of a recorded history of psychological trauma on NPS severity and associated caregiver distress, controlling for age and sex.

RESULTS

Among 41,876 eligible referrals with dementia, 6% (n = 2529) had some reference in their records to a history of psychological trauma. Referrals with a recorded history of psychological trauma were rated with a higher rate of both NPS severity (mean = 12.0) and associated caregiver distress (mean = 16.5) at service entry than those without a recorded history of psychological trauma (means = 10.7 and 14.5, respectively). A recorded history of psychological trauma was associated with higher odds of psychotic symptoms, agitation/aggression, irritability, disinhibition, affective symptoms and night-time behaviours.

CONCLUSIONS

Traumatic stress symptoms may represent a neglected target for intervention to reduce the impact of NPS in people with dementia.

Comparing clinico-demographics and neuropsychiatric symptoms for immigrant and non-immigrant aged care residents living with dementia: a retrospective cross-sectional study from an Australian dementia-specific support service

BACKGROUND

Neuropsychiatric symptoms of dementia such as agitation and aggression are common in people living with dementia. The presentation of neuropsychiatric symptoms is influenced by the cultural background of people living with dementia. Further, identifying factors contributing to neuropsychiatric symptoms may be complicated if people living with dementia are immigrants or from non-English-speaking backgrounds. Most of what is known about differences in neuropsychiatric symptoms between racial and ethnic groups living with dementia come from community-based samples. This study investigated differences in clinico-demographics and neuropsychiatric symptoms between immigrants and non-immigrants living with dementia in residential aged care homes who were referred to two Dementia Support Australia programs.

METHODS

This was a retrospective observational cross-sectional study from 2018 to 2022 using data extracted from the Dementia Support Australia database. Immigrant status was identified by documented country of birth. We conducted exploratory subgroup analyses for English-speaking or non-English-speaking immigrants in comparison to non-immigrants. Neuropsychiatric Inventory and PainChek® were used to assess neuropsychiatric symptoms of dementia and pain, respectively.

RESULTS

Of the 23,889 referrals, 36% were immigrants living with dementia. Immigrants were 0.8 years older than non-immigrants on average. Immigrants had a slightly higher prevalence of mixed dementia (9.5%) than non-immigrants (8.2%). Overall, the groups had no difference in the severity of neuropsychiatric symptoms and associated caregiver distress. However, there was a significant difference in the total number of neuropsychiatric inventory domains (Cohen's d = -0.06 [-0.09, - 0.02], p <.001) between non-English-speaking immigrants and non-immigrants. Immigrants were more likely to present with agitation/aggression, while non-immigrants were more likely to present with hallucinations. Factors contributing to neuropsychiatric symptoms were common between the groups, with language barriers and cultural considerations frequently endorsed for immigrants.

CONCLUSION

This study reveals a mixed picture of neuropsychiatric symptoms between immigrants and non-immigrants. However, due to the exploratory nature of the hypotheses, our findings need to be replicated in future studies to confirm any conclusions. There is a need for increased awareness on the impact of culture and language on neuropsychiatric symptoms for people receiving residential care. Future studies investigating neuropsychiatric symptoms in different immigrant groups will help increase our understanding of neuropsychiatric symptoms for all people.

Dying with behavioral and psychological symptoms of dementia in Australian nursing homes: a retrospective case-control study

Objectives

To identify predictors of mortality in people with active and challenging behavioral and psychological symptoms of dementia (BPSD).

Design

A retrospective case-control study was designed to compare those referred to Dementia Support Australia (DSA) who died in the 12 months to November 2016, with an equal number of controls who did not die. An audit tool was designed after literature review and expert opinion from the service. Odds ratio calculations and the Mann-Whitney U test were used to assess for difference.

Setting

Residents of Australian residential aged care facilities with BPSD referred to the DSA service.

Participants

Of 476 patients referred to DSA during the study period, 44 died. 44 controls were randomly selected from those remaining matched for age and sex.

Results

Significant differences included higher rates of benzodiazepine use, drowsiness, delirium, reduced oral intake and discussions about goals of care in those who died. Those who died were referred to the service for a shorter period and had more frequent contact between DSA and nurses at the nursing homes. Increase in opioid use and loss of skin integrity in those who died approached significance. The overall end of life course demonstrated a complex set of needs with frequent delirium, pain and frailty.

Conclusion

Further study is required to determine the optimal care for those with BPSD at the end of their lives. This study would indicate complex end of life care needs and point to a role for palliative care support.

Tailoring a complex intervention to reduce antidepressants in institutionalized older persons with dementia

INTRODUCTION

First-line treatment for behavioral and psychiatric symptoms of dementia is non-pharmacological. Still, psychotropic medication is widely used, despite its limited effect and harmful side-effects. More than half of all nursing home residents with dementia receive antidepressants, even though deprescribing is safe and feasible. Interventions to promote deprescribing of antidepressants in nursing homes are few and complex. To optimize the deprescribing process through an intervention, transparency for the development of the intervention is needed. We aim to describe the steps in the development and tailoring of an intervention targeting GPs, nursing home staff, and relatives to enhance collaboration on reducing the use of antidepressants in institutionalized older persons with dementia in Denmark.

METHOD

A step-wise process guided by the core elements in the Medical Research Council constituted the tailoring process. Five steps were included; 1) a literature search, 2) interviews with stakeholders, 3) drafting the intervention prototype, 4) professionals' assessment of the intervention, and 5) refinement of the intervention. The steps were conducted from June 2020 to June 2022.

RESULTS

Based on the literature search, interviews with stakeholders, and professionals' assessment of the intervention, four main themes were identified; 1) focusing on antidepressants, 2) importance of professional qualifications, 3) collaboration and communication, and 4) patient and relative involvement. They guided intervention development and refinement of the final intervention, which included 1) a case-based training course and 2) a dialog tool including a symptom assessment scale to be used in a structured consultation at the nursing home.

CONCLUSION

This study presents a detailed account of the tailoring process for a complex intervention to optimize deprescribing of antidepressants for older persons with dementia at nursing homes. By presenting a thorough development process, we expect to achieve increased adherence to the intervention which is currently being tested in an ongoing cluster randomized controlled trial. The transparency of the process will also increase the future development of other similar complex interventions.

Clinico-demographics of people with younger-onset dementia and neuropsychiatric symptoms referred to an Australian dementia support service: A comparison study with older-onset dementia

OBJECTIVE

Younger-onset dementia accounts for about 5-10% of all dementias in Australia. Little data is available on neuropsychiatric symptoms in people with younger-onset dementia compared to those with older-onset dementia. This study aims to compare the types of neuropsychiatric symptoms and their clinico-demographic characteristics of people with younger-onset dementia and older-onset dementia who are referred to a specific dementia support service.

METHODS

A 2-year retrospective observational cross-sectional analysis was undertaken on referrals with neuropsychiatric symptoms from Dementia Support Australia programmes. Neuropsychiatric symptoms were measured using the Neuropsychiatric Inventory total severity scores and distress scores. Contributing factors to neuropsychiatric symptoms for dementia groups were examined. Logistic regression was used to examine the relationship between individual neuropsychiatric symptoms and having older-onset dementia vs younger-onset dementia.

RESULTS

Of the 15,952 referrals, about 5% (n = 729, mean age: 60.7 years, standard deviation = 5.4) were individuals with younger-onset dementia. Referrals with older-onset dementia were more likely to be female (56%), whereas referrals with younger-onset dementia were more likely to be male (54%). There was a four times greater rate of frontotemporal dementia for those with younger-onset dementia (16.0%, n = 117) compared to those with older-onset dementia (2.8%, n = 427), χ² (1) = 366.2, p < 0.001. Referrals with younger-onset dementia were more likely to be referred from community settings and those with older-onset dementia were more likely to be from residential aged care. Overall, there was no difference in the severity and distress of neuropsychiatric symptoms between the two groups. Contributing factors to neuropsychiatric symptoms were different between the groups, with pain being more frequently endorsed for individuals with older-onset dementia whereas communication difficulties were more commonly identified for those with younger-onset dementia.

CONCLUSION

Clinico-demographics of referrals with younger-onset dementia differ from those with older-onset dementia. There were some differences in the characteristics of neuropsychiatric symptoms between younger-onset dementia and older-onset dementia. Our findings have implications for service provision and support for people with dementia at different ages.

Depression among caregivers of patients with dementia: Associative factors and management approaches

As elderly people increasingly come to represent a higher proportion of the world’s population, various forms of dementia are becoming a significant chronic disease burden. The World Health Organization emphasizes dementia care as a public health priority and calls for more support for family caregivers who commonly play a significant, central role in dementia care. Taking care of someone with dementia is a long-term responsibility that can be stressful and may lead to depression among family caregivers. Depression and related behavioral and cognitive changes among caregivers could in turn affect the status and prognosis of the dementia patient. This review article explores depression in dementia caregivers and summarizes proposed mechanisms, associated factors, management and research findings, and proposes future research directions.

Comparing Behavioral and Psychological Symptoms of Dementia and Caregiver Distress Caused Between Older Adults With Dementia Living in the Community and in Nursing Homes

OBJECTIVES

To investigate differences in behavioral and psychological symptoms of dementia (BPSD) and caregiver distress caused between older adults with dementia living in the community and in nursing homes.

DESIGN

A comparative cross-sectional study.

SETTING AND PARTICIPANTS

Participants were recruited from outpatient clinics of a tertiary psychiatric hospital and dementia units of a nursing home in Guangzhou, China.

METHODS

Neuropsychiatric Inventory was used to assess symptoms and caregiver distress. Dementia severity was determined using the Clinical Dementia Rating.

RESULTS

This study included 157 community and 112 nursing home residents with dementia. Clinically significant symptoms (item score ≥ 4) were found in 88.5% of the former and 75% of the latter. Caregivers of 79.6% of the former and 26.8% of the latter reported that at least one of these caused them moderate-to-severe distress (distress score ≥ 3). Among the community patients, anxiety was the most frequent "very severe" symptom, while sleep disorders and agitation caused the most frequent "very severe" caregiver distress. After controlling for dementia severity and medication use, family caregiving remained an independent risk predictor for clinically significant symptoms and moderate-to-severe caregiver distress. The prediction of caregiver distress based on symptom scores varied across caregiver types and individual symptoms (R² 0.36-0.82). Group differences in clinically significant symptoms and moderate-to-severe caregiver distress showed at the stage of moderate-to-severe dementia.

CONCLUSIONS AND IMPLICATIONS

Tailored management strategies to relieve family caregivers' BPSD-induced distress are needed, especially at the stage of moderate-to-severe dementia. An effective service system should be established for supporting family caregivers to cope with BPSD.

Hearing Assessment and Rehabilitation for People Living With Dementia

Hearing impairment commonly co-occurs with dementia. Audiologists, therefore, need to be prepared to address the specific needs of people living with dementia (PwD). PwD have needs in terms of dementia-friendly clinical settings, assessments, and rehabilitation strategies tailored to support individual requirements that depend on social context, personality, background, and health-related factors, as well as audiometric HL and experience with hearing assistance. Audiologists typically receive limited specialist training in assisting PwD and professional guidance for audiologists is scarce. The aim of this review was to outline best practice recommendations for the assessment and rehabilitation of hearing impairment for PwD with reference to the current evidence base. These recommendations, written by audiology, psychology, speech-language, and dementia nursing professionals, also highlight areas of research need. The review is aimed at hearing care professionals and includes practical recommendations for adapting audiological procedures and processes for the needs of PwD.

What we need as we get older: needs assessment for the development of a community geriatrics service in an Australian context

Background

The aim of this study was to inform the development of a Community Geriatrics Service (CGS) that addressed the healthcare and social needs of community dwelling older people in an Australian context.

Methods

Stakeholders (N = 108) took part in a ‘needs assessment’ involving 30-min semi-structured interviews with general practitioners (GPs; N = 49), and three 2-h focus groups (community engagement meetings; N = 59) with older people, informal caregivers, allied healthcare workers, and nursing home directors. Data were transcribed and thematically coded, mapped to source and weighted to the frequency that the theme was raised across sources.

Results

Five themes informing CGS development and delivery emerged: active health conditions (management of behavioural and psychological symptoms of dementia, falls, multimorbidity, and other relevant conditions), active social challenges (patient non-compliance, need for aged care social workers, caregiver stress, elder abuse, social isolation, and stigma), referrals (availability of specialists, communication, specialist input, and advance care directives), access (lack of transport options, and inaccessibility of local geriatrics clinics and specialists), and awareness (lack of awareness, knowledge, and resources).

Conclusions

The CGS will need to address access, referral processes and health system navigation, which were perceived by stakeholders as significant challenges. These findings warrant the development of a CGS with an integrated approach to aged care, pertinent for the health and social needs of the elderly.

When responsive and reactive meet organic? Treatment implications of language use in the era of #BanBPSD

The aetiopathogenesis of behaviours and psychological symptoms of dementia (BPSD) is often subjective, complex and multifaceted, produced by an array of contributing factors, including biomedical, psychological, environmental and/or social factors. Alongside other contributing factors, organic aetiology of BPSD should be considered when devising therapeutic management plans. Although considered last resort, time‐limited antipsychotic treatment (≤3 months) may have a vital adjunct role in managing intractable, refractory, distressing and/or life‐threatening BPSD, such as delusions and hallucinations; but only after person‐centred psychosocial interventions are exhausted and fail to deliver any therapeutic response. If prescribed, careful monitoring of therapeutic responses and adverse effects of antipsychotics with de‐prescribing plans should be a top priority, as these agents have limited efficacies and serious adverse outcomes (e.g., mortality).
