Rehabilitation Approaches to the Management of Aggressive Behaviour Disorders after Acquired Brain Injury

Improving emotion regulation ability after brain injury: A systematic review of targeted interventions

Emotion dysregulation is a common sequela after a brain injury, and it can have serious negative consequences for individuals, families, and the community. A systematic review of the literature was conducted to identify and evaluate interventions designed to improve emotion regulation ability in adults with acquired brain injury. Studies were identified on ProQuest, PsycInfo, ScienceDirect, Scopus, and Web of Science; last searched on 3 August 2023. A review protocol was prospectively registered on PROSPERO (CRD42020218175). Risk of bias was assessed using the Cochrane Risk-of-Bias tool (version 2). Sixteen studies were included in the review comprising one case series, five pilot studies, four pre-post studies, and six RCTs. There was a total of 652 participants across studies. Fourteen of the sixteen studies reported statistically significant improvements in at least one emotional functioning variable. Ten studies reported medium-large effect sizes. Limitations included inconsistency in the measurement, reporting of intervention outcomes and processes. Future directions are discussed.

Evidence-Based Review of Randomized Controlled Trials of Interventions for the Management of Behavioral Issues in Individuals With Moderate to Severe Traumatic Brain Injury

OBJECTIVE

To present an evidence-based review of randomized controlled trials (RCTs) evaluating interventions for the management of behavioral issues post moderate to severe traumatic brain injury (MSTBI), as part of an extensive database that has been conceptualized as a living systematic review.

METHODS

Systematic searches were conducted in MEDLINE, PubMed, Scopus, CINAHL, EMBASE and PsycINFO, up to and including December 2022, for articles published in the English language, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The quality of RCT was assessed using the Physiotherapy Evidence Database (PEDro) scale, and level of evidence was assigned using a modified Sackett scale.

RESULTS

Forty-six RCTs examining interventions and outcome measures related to behavioral issues post-MSTBI were included. These studies collectively enrolled 3,267 participants. The majority of RCTs were conducted in the United States (n = 27; 58.7%) and 28 (60.9%) were conducted after 2010. Of these, 27 RCTs examined non-pharmacological interventions and 19 examined pharmacological interventions. Effective pharmacological treatments included amantadine and dexmedetomidine. Effective non-pharmacological interventions included sensory stimulation in the acute phase, anger self-management programs, peer mentoring, problem-solving, and emotional regulation. Psychotherapy showed conflicting evidence.

CONCLUSION

This evidence-based review provides a comprehensive overview of the research landscape of RCTs addressing behavior post-MSTBI. The findings from these RCTs may be valuable for health care professionals, researchers, and policymakers involved in the field of TBI and behavior.

A literature review of outcome and treatment options after acquired brain injury: Suggestions for adult offenders using knowledge from the general population

BACKGROUND

Acquired brain injury (ABI) is a major health problem, often with negative effects on behaviour and mental health as well as cognition. Prevalence of ABI is exceptionally high among offenders and increases their re-offending risk. Information on risk factors for ABI and its outcomes among offenders that could guide effective treatment for them is, nevertheless, scarce and dispersed. However, there is a more substantial literature about the general population that could inform work with brain-injured offenders, especially when selecting for samples or subgroups with similar relevant characteristics, such as lower socio-economic status (SES), pre-injury lower tested intelligence score (<85) and pre-injury mental health problems.

AIMS

To explore brain injury data from non-offender samples of otherwise similar socio-economic and mental health and ability characteristics to offenders then, first, to describe their untreated outcomes and, secondly, outcomes after frequently used interventions in these circumstances, noting factors associated with their effectiveness.

METHOD

Three databases were systematically searched for the years 2010-2022; first, using terms for brain injury or damage and cognitive (dys)function, mental health or quality of life. Second, in a separate search, we used these terms and terms for interventions and rehabilitation. In the second review, studies were selected for clear, distinguishable data on age, sex, SES and lifestyle factors to facilitate inferences for offenders. A narrative analytical approach was adopted for both reviews.

RESULTS

Samples with characteristics that are typical in offender groups, including lower SES, lower pre-injury intelligence quotient (<85), prior cognitive impairments and prior mental health problems, had poorer cognitive and behavioural outcomes following ABI than those without such additional problems, together with lower treatment adherence. With respect to treatment, adequate motivation and self-awareness were associated with better cognitive and behavioural outcomes than when these were low or absent, regardless of the outcome measured.

CONCLUSIONS

More complex pre-injury mental health problems and social disadvantages typical of offenders are associated with poorer post-brain injury recovery. This paper adds to practical knowledge by bringing together work that follows specific outcome trajectories. Overall, succesful ABI-interventions in the general population that aim at pre-injury difficulties comparable to those seen among offenders, show that personalising injury-specific treatments and taking account of these difficulties, maximised positive outcomes.

Behaviour support for people with acquired brain injury within the National Disability Insurance Scheme: an Australian survey of the provider market

BACKGROUND AND OBJECTIVES

People with acquired brain injury (ABI) may experience behaviours of concern that require therapy services, including behaviour support. In Australia, the implementation of a National Disability Insurance Scheme (NDIS) and development of the NDIS Quality and Safeguards Commission, has led to significant changes to behaviour support workforce processes, and the way behaviour support is funded, regulated and delivered to people with ABI who are Scheme participants. The aim of this study was to explore the current and future provider market of professionals providing behaviour supports to Scheme participants who experience ABI.

METHOD

An anonymous survey was designed and distributed via social media channels, an email listserv and professional association newsletters to professionals working within the NDIS in Australia. Data were analysed using descriptive statistics and content analysis.

RESULTS

One hundred and two surveys responses were analysed. A majority of professionals had an average understanding of the NDIS Quality and Safeguard Commission rules and policies on behaviour support. Responses to current and future registration as an NDIS Practitioner indicated the workforce gap could increase by between 17 and 26%. Respondents also raised concerns about the lack of training and experience of allied health professional students and graduates in addressing behaviours of concern. Responses to the open-ended question highlighted additional issues in the provision of behaviour support within the NDIS.

CONCLUSIONS

This research highlighted the need for an NDIS behaviour support workforce strategy and supply-side market intervention to ensure a viable and sustainable workforce for people with ABI who need behaviour support.

"Talk and Chalk": An emotion regulation intervention for anger after acquired brain injury

Uncontrollable anger is a debilitating consequence of acquired brain injury (ABI). This proof-of-concept study investigated the preliminary efficacy of an emotion regulation intervention for managing post-ABI anger. A secondary objective was to determine which participant characteristics were related to intervention gains. With a pre-post intervention design and three-month follow-up, there were five individually administered meetings on Zoom, over a four-month period. 24 adults who had sustained an ABI were enrolled. Participants were mostly males, from 24 to 85 years old. A series of one-way repeated-measures ANOVAs were conducted to determine the intervention's efficacy, and Spearman's rho bivariate correlations for the association between participant characteristics and intervention gains. Significant differences were observed in external anger from baseline to post-treatment; there were no further changes from post-treatment to follow-up. Of the participant characteristics, only readiness to change and anxiety were correlated. The proposed intervention presents a brief, feasible, and preliminary efficacious alternative for regulating post-ABI anger. Intervention gains are associated with readiness to change and anxiety, which has important implications for clinical delivery.

Mania Following Traumatic Brain Injury: A Systematic Review

OBJECTIVE

Traumatic brain injury (TBI) is a leading cause of mortality and morbidity worldwide. Mania is an uncommon, but debilitating, psychiatric occurrence following TBI. The literature on mania following TBI is largely limited to case reports and case series. In the present review, the investigators describe the clinical, diagnostic, and treatment characteristics of mania following TBI.

METHODS

A systematic search of MEDLINE, EMBASE, and PsycINFO was conducted for English-language studies published from 1980 to July 15, 2021. The included studies provided the required individual primary data and sufficient information on clinical presentation or treatment of manic symptoms. Studies with patients who reported a history of mania or bipolar disorder prior to TBI and studies with patients who sustained TBI before adulthood were excluded.

RESULTS

Forty-one studies were included, which reported information for 50 patients (the mean±SD age at mania onset was 39.1±14.3 years). Patients were more frequently male, aged <50 years, and without a personal or family history of psychiatric disorders. Although 74% of patients reported mania developing within 1 year following TBI, latencies of up to 31 years were observed. Illness trajectory varied from a single manic episode to recurrent mood episodes. Rapid cycling was reported in six patients. Mood stabilizers and antipsychotics were most frequently used to improve symptoms.

CONCLUSIONS

Heterogeneity of lesion locations and coexisting vulnerabilities make causality difficult to establish. Valproate or a second-generation antipsychotic, such as olanzapine or quetiapine, may be considered first-line therapy in the absence of high-level evidence for a more preferred treatment. Early escalation to combined therapy (mood stabilizer and second-generation antipsychotic) is recommended to control symptoms and prevent recurrence. Larger prospective studies and randomized controlled trials are needed to refine diagnostic criteria and provide definitive treatment recommendations.

Using the St Andrew's - Swansea Neurobehavioural Outcome Scale (SASNOS) to determine prevalence and predictors of neurobehavioural disability amongst survivors with traumatic brain injury in the community

Studies using the St Andrew's - Swansea Neurobehavioural Outcome Scale (SASNOS) confirm neurobehavioural disability (NBD) is highly prevalent in inpatient Neurobehavioural Rehabilitation and Stroke samples. However, a recent study amongst a Danish community sample of acquired brain injury survivors found a relative paucity of NBD symptoms; and when symptoms were present, they tended to be of mild severity. The current observational study employed the SASNOS to explore prevalence of NBD in survivors with traumatic brain injury (TBI) living in the community, the extent of survivors' self-awareness of NBD symptoms, and constructed prediction models of NBD. A de-identified data set was compiled, comprising data for 97 TBI survivors (74.2% men, mean time since injury 2.8 years). In addition to SASNOS self- and proxy-ratings, various demographic, clinical and injury-related characteristics were captured. NBD was found to be highly characteristic, although severity varied depending on subtype. Statistical comparison of self- and proxy-ratings did not support reduced self awareness regarding NBD, whereas treating the problem as one of inter-rater reliability suggested this was an issue. Executive impairment, depressed mood and sex were especially prognostic of NBD. Reasons accounting for differences in NBD between the community samples are discussed and recommendations for future research made.

Implementing a behavior management approach in the hospital setting for individuals with challenging behaviors during acute traumatic brain injury

PRIMARY OBJECTIVE

This study aimed to determine if implementing a clinically pragmatic behavior management approach for challenging behaviors during acute TBI reduces use of restraints, security incidences, acute length of stay admission and cost, thereby improving progress to rehabilitation.

RESEARCH DESIGN

This pilot study involved a behavior management group (n = 27), compared with a historical control group (n = 74).

METHOD AND PROCEDURES

The behavior management group received care following the implementation of a behavior management approach for challenging behaviors during acute TBI at two hospitals in South Australia.

MAIN OUTCOMES AND RESULTS

Fidelity results demonstrated high level of adherence to the implemented behavior management approach. The behavior management group had significant lower use of mechanical restraints (p = 0.03), and significantly lower acute admission costs (p = 0.034). Trends in lower pharmacological restraint usage, lower acute hospital length of stay and time from admission to rehabilitation acceptance were recorded.

CONCLUSIONS

These pilot results contribute to improving quality of health care but methodological limitations make outcomes difficult to interpret as a direct result of the intervention. Future studies are required to investigate evidence-based behavior management interventions for acute TBI patients using more rigorous knowledge translation implementation designs.

Shades of Rage: Applying the Process Model of Emotion Regulation to Managing Anger After Brain Injury

Uncontrollable anger is common following an acquired brain injury (ABI), with impaired emotion regulation (ER) being one of the main contributors. Existing psychological interventions appear moderately effective, though studies typically include limitations such as small sample sizes, issues of long-term efficacy, and standardization of content. While ER has been a popular research field, the study of ER for anger management after ABI is less well investigated, and contains few interventions based on the widely used Process Model of ER. This review surveys the efficacy of ER strategies in individuals with ABI, and proposes a novel research design for future interventions. Recommendations are made about: strategy number and type, shared decision-making, approaches to data analysis, and mode of delivery.

The Efficacy and Harms of Pharmacological Interventions for Aggression After Traumatic Brain Injury-Systematic Review

Background: Aggression is a commonly reported problem following traumatic brain injury (TBI). It may present as verbal insults or outbursts, physical assaults, and/or property destruction. Aggressive behavior can fracture relationships and impede participation in treatment as well as a broad range of vocational and social activities, thereby reducing the individual's quality of life. Pharmacological intervention is frequently used to control aggression following TBI. The aim of this systematic review was to critically evaluate the evidence regarding efficacy of pharmacological interventions for aggression following TBI in adults.

Methods: We reviewed studies in English, available before December 2018. MEDLINE, PubMed, CINAHL, EMBASE, PsycINFO, and CENTRAL databases were searched, with additional searching of key journals, clinical trials registries, and international drug regulators. The primary outcomes of interest were reduction in the severity of aggression and occurrence of harms. The secondary outcomes of interest were changes in quality of life, participation, psychological health (e.g., depression, anxiety), and cognitive function. Evidence quality was assessed using the Cochrane Risk of Bias tool and the Joanna Briggs Institute Critical Appraisal Instruments.

Results: Ten studies were identified, including five randomized controlled trials (RCTs) and five case series. There were positive, albeit mixed, findings for the RCTs examining the use of amantadine in reducing irritability (n = 2) and aggression (n = 2). There were some positive findings favoring methylphenidate in reducing anger (n = 1). The evidence for propranolol was weak (n = 1). Individual analysis revealed differential drug response across individuals for both methylphenidate and propranolol. The less rigorous studies administered carbamazepine (n = 2), valproic acid (n = 1), quetiapine (n = 1), and sertraline (n = 1), and all reported reductions in aggression. However, given the lack of a control group, it is difficult to discern treatment effects from natural change over time.

Conclusions: This review concludes that a recommendation for use of amantadine to treat aggression and irritability in adults following TBI is appropriate. However, there is a need for further well-designed, adequately powered and controlled studies of pharmacological interventions for aggression following TBI.

How local context influences access to neuropsychological rehabilitation after acquired brain injury in South Africa

The numbers of acquired brain injury (ABI) survivors in South Africa are increasing; however, facilities to provide neuropsychological rehabilitation are limited due to a lack of healthcare resources. The updated International Classification of Health, Functioning, and Disability (ICF) from the WHO emphasises how the context of an impairment influences the patient’s activity limitations and participation restrictions. This analysis examined South African contextual influences on the accessibility, quality and efficiency of neuropsychological rehabilitation interventions after ABI in South Africa. Three main contextual influences were identified, namely, socioeconomic disparities, sociocultural influences and discharge to underprepared communities. Systems thinking and inclusive models of healthcare are needed in low-income and middle-income countries, such as South Africa, where resource constraints necessitate creative and ecological forms of rehabilitation interventions after ABI. Contextual influences are vital to consider when designing neuropsychological rehabilitation interventions in order to improve the accessibility and relevance of these interventions and to ensure the effective utilisation of scarce healthcare resources.

Brain injury, behaviour support, and family involvement: putting the pieces together and looking forward

Purpose: (1) to provide insight into the family's experience and support needs following acquired brain injury (ABI) specific to behavioural changes; (2) to provide an overview of empirically-based behaviour support approaches for individuals with ABI; and (3), to examine family involvement in implementing behavioural interventions.Methods: Review of the literature.Results: Family members experience significant distress resulting from neurobehavioural changes in relatives with ABI, and report unmet informational and practical support needs regarding this issue. The importance of utilising family expertise within the rehabilitation process is widely acknowledged, with the increasing involvement of family members being promoted. There is growing evidence supporting the use of positive behaviour support approaches for individuals with ABI in community settings, and evidence supporting the involvement of family within behavioural interventions.Conclusions: This review suggests the need to develop alternative support models that shift the focus towards building competence in everyday support people rather than dependency on the service system. A bottom-up approach is recommended, with the aim of addressing unmet support needs and increasing the competence of family members in supporting behaviour change in individuals with ABI. Recommendations are provided in informing an optimal community-based neurobehavioural support model. Implications for RehabilitationPositive behaviour support is recommended in supporting behavioural changes following brain injury, with family expertise utilised in this process.Evidence suggests that family members can be effectively trained in developing and implementing behaviour support strategies.Family involvement in behavioural interventions may address unmet support needs and increasing the competence of family members in supporting behavioural changes following brain injury.

The Overt Behaviour Scale-Self-Report (OBS-SR) for acquired brain injury: exploratory analysis of reliability and validity

The objectives were to test the properties, via a psychometric study, of the Overt Behaviour Scale-Self-Report (OBS-SR), a version of the OBS-Adult Scale developed to provide a client perspective on challenging behaviours after acquired brain injury. Study sample 1 consisted of 37 patients with primary brain tumour (PBT) and a family-member informant. Sample 2 consisted of 34 clients with other acquired brain injury (mixed brain injury, MBI) and a service-provider informant. Participants completed the OBS-SR (at two time points), and the Awareness Questionnaire (AQ) and Mayo Portland Adaptability Inventory-III (MPAI-III) once; informants completed the OBS-Adult and AQ once only. PBT-informant dyads displayed "good" levels of agreement (ICC_2,k = .74; OBS-SR global index). Although MBI-informant dyads displayed no agreement (ICC_2,k = .22; OBS-SR global index), the sub-group (17/29) rated by clinicians as having moderate to good levels of awareness displayed "fair" agreement (ICC_2,k = .58; OBS-SR global index). Convergent/divergent validity was demonstrated by significant correlations between OBS-SR subscales and MPAI-III subscales with behavioural content (coefficients in the range .36 -.61). Scores had good reliability across one week (ICC_2,k = .69). The OBS-SR took approximately 15 minutes to complete. It was concluded that the OBS-SR demonstrated acceptable reliability and validity, providing a useful resource in understanding clients' perspectives about their behaviour.

Characterisation of aggression in Huntington's disease: rates, types and antecedents in an inpatient rehabilitation setting

AIMS AND OBJECTIVES

To systematically review aggression in an inpatient Huntington's cohort examining rates, types and antecedents.

BACKGROUND

Although the prevalence of aggression in Huntington's disease is high, research into this problematic behaviour has been limited. Few studies have investigated the nature of aggressive behaviour in Huntington's disease or antecedents that contribute to its occurrence.

DESIGN

A systematic, double-coded, electronic medical file audit.

METHODS

The electronic hospital medical records of 10 people with Huntington's disease admitted to a brain disorders unit were audited for a 90-day period using the Overt Aggression Scale-Modified for Neurorehabilitation framework, yielding 900 days of clinical data.

RESULTS

Nine of 10 clients exhibited aggression during the audit period. Both verbal (37·1%) aggression and physical aggression were common (33·8%), along with episodes of mixed verbal and physical aggression (15·2%), while aggression to objects/furniture was less prevalent (5·5%). The most common antecedent was physical guidance with personal care, far exceeding any other documented antecedents, and acting as the most common trigger for four of the nine clients who exhibited aggression. For the remaining five clients, there was intraindividual heterogeneity in susceptibility to specific antecedents.

CONCLUSION

In Huntington's sufferers at mid- to late stages following disease onset, particular care should be made with personal care assistance due to the propensity for these procedures to elicit an episode of aggression. However, given the degree of intraindividual heterogeneity in susceptibility to specific antecedents observed in the present study, individualised behaviour support plans and sensory modulation interventions may be the most useful in identifying triggers and managing aggressive episodes.

RELEVANCE TO CLINICAL PRACTICE

Rates of aggression in Huntington's disease inpatients can be high. Knowledge of potential triggers, such as personal care, is important for nursing and care staff, so that attempts can be made to minimise distress for patients and maximise the personal safety of care staff.

What can structured professional judgement tools contribute to management of neurobehavioural disability? Predictive validity of the Short-Term Assessment of Risk and Treatability (START) in acquired brain injury

Aggression is a frequently cited outcome of acquired brain injury (ABI). Paradoxically, evidence suggests that ABI clinicians underestimate the risk of violence, and aggression in neurobehavioural services appears more frequent than in forensic/secure psychiatric settings. Risk assessment tools are endemic in the latter and highly beneficial in managing harm. However, none has been validated for ABI. This study examines the predictive validity of ABI violence using one established tool, the Short-Term Assessment of Risk and Treatability (START). It is argued that successful management of aggression in neurobehavioural rehabilitation is partly attributable to ongoing programme calibration following regular review of measures conceptualised for ABI. The predictive ability of START and ABI measures was determined through correlational, receiver operating characteristic and hierarchical multiple regression analyses, using 4559 aggression recordings concerning 76 patients over 4 weeks. The START risk of violence was classed "low" for 50% of the sample and "high" for 13.7%. Significant relationships between individual measures and aggression were evident. However, multivariate analysis confirmed that the best fitting model comprised ABI measures of neurobehavioural disability and functional abilities: START data did not increase explained variance. ABI risk prediction may benefit from development of specific tools. However, these should be conceptualised for ABI to incorporate the diverse range of variables underpinning neurobehavioural disability.

Challenging Behaviours, Co-morbidities, Service Utilisation and Service Access among Community-dwelling Adults with Severe Traumatic Brain Injury: A Multicentre Study

Objective: To examine patterns, predictors and unmet needs of service utilisation and access to mental health and/or drug and alcohol services among community-dwelling adults with severe traumatic brain injury, and compare those who displayed challenging behaviours with those not displaying challenging behaviour.

Design: Retrospective multicentre study.

Subjects: All active clients (n= 507) of the New South Wales (NSW) Brain Injury Rehabilitation Program (BIRP) community rehabilitation teams.

Methods: Clinician-rated data were collected on client challenging behaviours, mental health and functional status, service utilisation and unmet needs. Between-groups analyses (challenging behaviour versus no challenging behaviours) were conducted to examine patterns of service utilisation and unmet needs. Predictors for service utilisation were tested by multiple linear regression.

Results: Challenging behaviours were associated with higher use of BIRP and non-BIRP services and greater levels of unmet needs. Challenging behaviour was an independent predictor of higher levels of service utilisation, in conjunction with pre- and post-injury mental health and drug and alcohol co-morbidities and geographic location. Only 15.3% of the 111 clients with challenging behaviours and co-morbid drug and alcohol problems accessed a drug and alcohol service, while another 32.4% had unmet needs for such services.

Conclusion: Challenging behaviours make an independent contribution to increased levels of service utilisation after severe traumatic brain injury.
