Post-traumatic stress disorder mistaken for behavioural and psychological symptoms of dementia: case series and recommendations of care

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.

Weaving Evidence into Action for Veterans with Dementia (WEAVE): Evaluation of implementation into long-term care practice

RATIONALE

Veterans living with dementia in long-term care have complex needs, with variable manifestation of symptoms of dementia that interact with their lived experience. Best practice dementia care prioritises nonpharmacological interventions; of which few have strong evidence. Implementation of evidence is complex, with evaluation of outcomes and processes necessary.

AIMS AND OBJECTIVES

This paper details the evaluation of implementation, at veteran and organisational level, of the Weaving Evidence into Action for Veterans with Dementia (WEAVE) programme.

METHODS

A Type 2 hybrid effectiveness-implementation design was used, underpinned by the Implementation Framework for Aged Care (IFAC). Programme intervention incorporated music therapy, exercise, reminiscence therapy and/or sensory modulation, offered over a 24-week period. Evaluation components included: (1) programme effectiveness for veterans with dementia for responsive behaviour, physical wellbeing, cognitive status, emotional state, medications and falls (at baseline, 8-week, 16-week and 24-week); and (2) implementation outcomes of reach and adoption, feasibility and acceptability, fidelity (via interviews) and a preliminary cost analysis.

RESULTS

Thirty-eight veterans participated in the 24-week programme, with high levels of engagement in interventions of their choice. Statistically significant improvements were seen across all veteran-level outcome measures, for functional capacity and reduced neuro-psychiatric and depressive symptoms. Ten staff members were interviewed, highlighting co-designed core elements were feasible and acceptable, and the momentum generated by resident and staff enthusiasm. Cost analysis included costs of programme set-up and running the 24-week intervention.

CONCLUSION

Key components of programme success were the therapeutic leaders, adherence to core elements of programme design, and veterans' choice in meaningful activity. Cost analysis supports deliberations for upscale across further care homes.

Weaving Evidence into Action for Veterans with dementia (WEAVE): Codesigning the implementation of nonpharmacological interventions for programme fidelity and sustainability

RATIONALE

Challenges associated with translating evidence into practice are well recognised and calls for effective strategies to reduce the time lag and successfully embed evidence-based practices into usual care are loud and clear. While a plethora of nonpharmacological interventions for people with dementia exist; few are based on strong evidence and there is little consideration for programme operationalisation in the complex environment of long-term care.

AIMS AND OBJECTIVES

This paper describes the preparation for the implementation of the Weaving Evidence into Action for Veterans with dementia project, incorporating the codesign of delivery of four evidence-based, nonpharmacological interventions.

METHOD

Implementation preparation for this type 2 hybrid effectiveness-implementation project was underpinned by the Implementation Framework for Aged Care (IFAC). A sociocultural-political contextual scan was undertaken, and reflection on the IFAC question 'why change?' with key stakeholders. Delivery of the four interventions of music therapy, exercise, reminiscence therapy and sensory modulation was explored using codesign methodology. Preparation of both intervention delivery personnel and recipients was via training, establishment of a change team and promotional/awareness-raising strategies.

RESULTS

The contextual scan revealed Australian government reforms and organisational imperatives facing long-term care services, while reflections on 'why change' flagged best practice dementia care at the local care home level. Several codesign sessions involved veterans with dementia, family members, care home staff members and volunteers to ensure programme alignment with needs and preferences, accounting for existing activities. Training was designed and delivered before programme commencement. A change team was established and strategies to support behaviour change instigated. Implementation evaluation is reported elsewhere.

CONCLUSION

The extended preparatory period for implementation, afforded by the COVID-19 pandemic on programme commencement, enabled time for widespread understanding of the programme and necessary upskill of staff. Comprehensive codesign with all stakeholders of programme components identified core and flexible elements necessary for fidelity of implementation.

Treatment of post-traumatic stress disorder in people with dementia: a structured literature review

Post-traumatic stress disorder (PTSD) is associated with cognitive dysfunctions and is an independent risk factor for dementia. A recent study has found the prevalence of PTSD in people with dementia is 4.7%-7.8%. However, little is known about the effectiveness of PTSD treatment for people with dementia. The primary aim of the current study is to review previous studies on the treatment of PTSD in people with dementia. A structured literature review was performed using a 'Preferred Reporting Items for Systematic Reviews and Meta-Analyses' analysis in PubMed, Embase, PsycINFO and CINAHL. Two independent researchers screened titles and abstracts. The inclusion criteria were: PTSD symptoms present, diagnosis of dementia, PTSD treatment form described and effects of the treatment mentioned. Articles that matched these criteria were included and content and quality were analyzed. We included nine articles, all case reports, with a total of 11 cases. The discussed treatment options are eye movement desensitisation and reprocessing (EMDR) (n = 3), prolonged exposure (n = 1), cognitive behavioural therapy (n = 1) and pharmacological treatment (n = 4). All articles reported a positive effect of the intervention on several monitored symptoms. Evidence for positive effects and feasibility of EMDR were most reliable, and it was applied in two articles of sufficient quality published in 2018 and 2019. EMDR 'on-the-spot' was described with positive effect in one article in which three cases were discussed. The quality of included papers ranged from insufficient to sufficient. This review shows that people with PTSD and dementia can benefit from PTSD treatment. EMDR, prolonged exposure, acceptance and commitment therapy and pharmacological treatment are applicable in this population. EMDR treatment is most described in this population (n = 5) and shows positive results, and the studies are of sufficient quality (n = 3). Further research in the form of a randomised controlled trial is required to study the effectivity of different treatment interventions in this population.

The Need for a Diagnostic Instrument to Assess Post-Traumatic Stress Disorder in People with Dementia: Findings from a Delphi Study

Cognitive and behavioral aspects may mask posttraumatic stress disorder (PTSD) in people with dementia. PTSD severely lowers quality of life in people with dementia. Proper recognition of PTSD is essential to ensure adequate treatment. However, a valid diagnostic tool for PTSD in dementia is lacking. A Delphi study was conducted among 20 Dutch and 6 international experts in the field of PTSD and dementia care or research. The aim was to reach consensus in 3 rounds on the added value, form, content, and application for developing such an instrument. The first round confirmed the need for a new diagnostic tool for research and clinical practice. Consensus was reached on 23 statements regarding the support base and 19 related to content of the instrument. In the third round, opinions on several conceptual problems were gathered. Based on the experts' opinions, a draft version of an instrument, the TRAuma and DEmentia-interview (TRADE-interview), was developed. Clinical and research implications of this new measure are discussed.

Treating Symptoms of Posttraumatic Stress in People with Dementia: Expert Consensus Using the Delphi Method

OBJECTIVES

Posttraumatic stress disorder is frequently present in people with dementia, but the symptoms are difficult to recognize and suitable treatments are lacking. The aim of the present study was to investigate which trauma-focused treatments are applicable to these patients.

METHODS

The Delphi method is a process which is used to reach consensus from a panel of experts. The study was conducted online and consisted of three rounds with statements about support for treatment, treatment, and implementation.

RESULTS

There are several treatment options available, but it depends on the symptoms, and the severity of PTSD and dementia which treatment is most suitable.

CONCLUSIONS

The outcomes offer some practical tips for health care workers, and they provide a fundamental base for future research.

CLINICAL IMPLICATIONS

Clinicians should pay attention to the treatment of PTSD symptoms in people with dementia and it is necessary to examine the type and severity of both PTSD symptoms and dementia. Taking these factors into account, clinicians are able to focus on the best treatment option in order to improve the quality of life of these specific type of patients.

Care aides' perceptions of caring for residents with a history of psychological trauma in Western Canadian care homes

OBJECTIVE

To explore care aide perceptions of caring for residents who aides perceived had past psychological trauma.

METHODS

Through cognitive interviews, we developed a definition of trauma for four survey questions about caring for residents with psychological trauma. We added these questions to our routine care aide survey in 91 care homes in Western Canada (September 2019 to February 2020). We asked if care aides perceived that they were caring for residents with trauma, how often, types of trauma experienced, and what indication led them to perceive a resident had experienced trauma. We analyzed data using content analysis (open-ended questions) and regression analyses (closed-ended questions).

RESULTS

Three thousand seven hundred and sixty five care aides responded (70% response rate) to the survey, and 53% perceived caring for one or more residents with a history of psychological trauma in the previous 2 weeks. Within six categories of traumatic events, abuse (35%) and war exposure (26%) were most common. Most common indications of trauma reported by care aides (five categories) were reliving the experience or having intrusive symptoms (28%) and avoidant behaviors (24%). Care aides were more likely to report caring for a resident who they perceived had experienced past psychological trauma if they were younger, spoke English as their first language, self-reported experiencing more aggression from residents, or who worked in not-for-profit homes.

CONCLUSIONS

This preliminary study supports the need for further study of care aides' perceptions and experiences of caring for residents with past trauma, and the effects of caring for these residents on quality of work life.

Characterising trauma-informed aged care: An appreciative inquiry approach

OBJECTIVE

While Trauma-informed care (TIC) has the potential to improve the quality of aged and dementia care, the challenge remains in translating the principles of TIC into practice. This study aimed to characterise what trauma-informed aged care looks like in practice, by learning from an aged care service acknowledged as delivering trauma-informed aged care effectively.

METHOD

We conducted an appreciative inquiry study within a residential aged care service catering for veterans and others with trauma histories. Observation of care behaviours, interviews with staff and residents, and organisational policy mapping were used to identify elements that maximised care safety and accessibility for trauma survivors. Data were analysed and triangulated using a framework analysis approach.

RESULTS

The aged care provider embedded the principles of TIC into its staff training (i) to promote understanding of how trauma may affect experiences in care, and (ii) to adapt care when appropriate to promote safety. The service promoted a calm atmosphere where residents could make choices and felt safe. Uniforms and signage provided consistency, clarity, and transparency for residents. Staff behaviours demonstrated respect, fostered trust, and anticipated needs without unnecessarily imposing care. Staff consistently offered choices, used residents' names, sought permission before providing care, and offered reassurance. Staff reported high morale with a commitment to delivering high quality care, and feedback to management. Effective communication promoted information sharing and trust among staff.

CONCLUSION

Trauma-informed practice was facilitated through organisational policy, a dignified environment, and thoughtful staff behaviour creating safety, choice, and control for residents.

Delivering Trauma-Informed Care in a Hospital Ward for Older Adults With Dementia: An Illustrative Case Series

Introduction

Up to 70% of older adults have experienced a psychologically traumatic event in their life. Traumatic events can have lifelong effects on functioning and emotion regulation and can affect behavior and experiences in care settings. Common healthcare practices and environments can be re-traumatizing for trauma survivors. These features may trigger behavior change (e.g., aggression and agitation) particularly after the onset of dementia. However, very little research exists to understand how the effects of traumatic events manifest in aged care settings. Trauma-informed care is a framework in which the potential impact of trauma is acknowledged, and practices and procedures are adapted to maximize feelings of control and safety for the patient. Trauma-informed care is an innovative approach with little published evidence in acute geriatric settings.

Methods

We present a series of cases to demonstrate how psychological trauma can affect the experience of inpatient care for older people. The cases detail the patients' relevant background, triggers and behaviors followed by the steps taken by staff to support the patient and respond to their trauma-related needs. These cases describe how the principles of trauma-informed care can be applied to recognize when past psychologically traumatic events are impacting the older adult in hospital. The outcomes of these interventions are reported on in terms of their impact on challenging behavior, patient experiences and satisfaction with care, and/or staff confidence and skill.

Findings

A range of past events negatively impacted the patients during their time in hospital, including childhood abuse, military service, and domestic violence. Staff implemented strategies to accommodate trauma-related needs while providing care that improved safety and reduced patient distress. Principles of trauma-informed care were applied where able, including providing choices and enabling autonomy. However, organizational and environmental features of inpatient wards continued to pose risks for re-traumatisation.

Conclusions

Trauma-informed care is an under-utilized yet potentially beneficial approach to care for older adults in the hospital setting. The cases detailed here demonstrated that the impact of psychological trauma requires an individualized response from staff which when effectively implemented can promote staff and patient safety, reduce the risk of re-traumatisation, and minimize adverse events.

A first insight into the clinical manifestation of posttraumatic stress disorder in dementia: a systematic literature review

Posttraumatic stress disorder (PTSD) is a prevalent disorder worldwide and often co-occurs in dementia. Both have a major impact on disease burden and quality of life. PTSD may be difficult to recognize in dementia and a structured diagnostic method is lacking. In order to get insight into the clinical diagnostics of PTSD in dementia, this systematic literature review evaluates the clinical presentation of PTSD and other relevant symptoms in people with dementia. PubMed, PsycINFO, Embase, and CINAHL were searched for all publications through 30 December 2021. Articles were included which met the following criteria: (i) description of at least one case with a current diagnosis of dementia and co-morbid PTSD; (ii) clinical presentation of symptoms being adequately described; (iii) no difference being made between chronic PTSD, PTSD with re-activation, and delayed onset PTSD. Of the 947 identified abstracts, 13 papers met the inclusion criteria and were included (describing 30 cases). Based on our rating, only one case completely fulfilled the DSM-5 criteria of PTSD. Avoidance was only described in three cases. Most commonly described symptoms were irritability and anger (E1, 9%), persistent negative emotional state (D4, 9%), and sleep disturbances (E6, 8%). In 93% of the case reports, other symptoms were also described, i.e. memory problems (58%), screaming (33.3%), and wandering (22.2%). People with dementia who have experienced a traumatic event seem to present, based on our rating method, with insufficient symptoms to meet all criteria for a PTSD DSM-5 diagnosis. The DSM-5 core symptom of avoidance was absent in most of the cases. Clinical presentation consists mainly of symptoms of irritability, anger, persistent negative emotional state, and sleep disturbances, often accompanied by other symptoms. These findings suggest that older people with dementia may have other symptom presentations than people without dementia.

Understanding how Canadian healthcare providers have learned to identify co-occurring PTSD symptoms and dementia in Veterans

WHAT IS KNOWN ON THE SUBJECT?: Little is known about how PTSD and dementia in Veterans is identified by health care providers. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: Healthcare providers identify those behavioural symptoms experienced by older people living with dementia that represent an unmet need associated with PTSD secondary to military service. Once healthcare providers recognize the presence of symptoms relevant to PTSD, they modify their care approach to include focused/tailored non-pharmacological care interventions that address environmental and situational variables that reflect military action. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Specialized education and training is needed to improve the identification of PTSD when existent with other co-occurring neurocognitive conditions such as delirium, dementia and depression. ABSTRACT: Introduction Co-occurring PTSD and dementia in Veterans can be difficult to distinguish from dementia-related responsive behaviours, which may result in inappropriate care management. Improved identification of PTSD and dementia is necessary to inform more appropriate and effective care for Veterans. Aim/Question The purpose of this study was to understand how Canadian healthcare providers have learned to identify the co-occurrence of PTSD symptoms in Veterans with dementia. Methods Eight semi-structured interviews employing the Critical Incident Technique were conducted with key informant healthcare providers who treat Veterans from across Canada. Framework analysis was used to code, sort and develop themes. Results Observed differences in Veterans with PTSD and dementia cued healthcare providers to seek our more information, leading to a new understanding of past trauma underlying the symptoms they observed. Healthcare providers then altered their usual care approaches to utilize trust-based and validation-oriented strategies resulting in more effective care management. Discussion Improvement in the identification of co-occurring PTSD and dementia in Veterans requires specialized education and training for healthcare providers. Implications for Practice Recognizing the complex needs of older Veterans with co-occurring PTSD and dementia is necessary for healthcare providers to implement more effective care for this population. Relevance Statement This paper provides mental health nurses with new understanding of co-occurring PTSD and dementia in Veterans. With an ageing Veteran population in Canada, mental health nurses need to be knowledgeable about the care for Veteran specific mental health needs.

PTSD Symptoms and Dementia in Older Veterans Who are Living in Long-Term Care

Co-occurring posttraumatic stress disorder symptoms and dementia can result in increased symptoms, such as suspicion, aggression, and nightmares in Veterans that can be difficult to manage in long-term care environments. The objective of the study was to explore how the co-occurrence of posttraumatic stress disorder symptoms and dementia are understood in Canadian Veterans who are living in long-term care. A descriptive multiple case study was conducted in two Veteran long-term care facilities in Canada. Data collection consisted of semi-structured interviews with Veterans, their family caregivers, and health care providers, non-participant observation, and a chart audit. Three major themes emerged relating to symptom expression and care approach: a) symptoms are the same but different; b) differences in the complexity of care; and c) added dimensions involved in care. The results of this study contribute foundational information about co-occurring posttraumatic and dementia symptoms that can inform policy, care approaches, and potential interventions.
