A biopsychosocial deconstruction of “personality change” following acquired brain injury

Experimentally-evidenced personality alterations following meningioma resection: A case report

Personality changes following neurosurgical procedures remain poorly understood and pose a major concern for patients, rendering a strong need for predictive biomarkers. Here we report a case of a female patient in her 40s who underwent resection of a large sagittal sinus meningioma with bilateral extension, including resection and ligation of the superior sagittal sinus, that resulted in borderline personality disorder. Importantly, we captured clinically-observed personality changes in a series of experiments assessing self-other voice discrimination, one of the experimental markers for self-consciousness. In all experiments, the patient consistently confused self- and other voices - i.e., she misattributed other-voice stimuli to herself and self-voice stimuli to others. Moreover, the electroencephalogram (EEG) microstate, that was in healthy participants observed when hearing their own voice, in this patient occurred for other-voice stimuli. We hypothesize that the patient's personality alterations resulted from a gradual development of a venous collateral hemodynamic network that impacted venous drainage of brain areas associated with self-consciousness. In addition, resection and ligation of the superior sagittal sinus significantly aggravated personality alterations through postoperative decompensation of a direct frontal lobe compression. Experimentally mirroring clinical observations, these findings are of high relevance for developing biomarkers of post-surgical personality alterations.

Living in a reshaped reality: Exploring social participation and self-identity after TBI

Individuals with a moderate to severe traumatic brain injury (TBI) experience substantial changes in their life. This constructivist grounded theory study aimed to develop an explanatory model that explores the impact of changes in social participation and self-identity after sustaining a TBI. Sixteen participants with moderate to severe TBI (mean age = 49.8, 69% male) were recruited, and were on average 16.4 years post-injury (SD = 10.4). Data from semi-structured interviews were analysed thematically. An overarching theme of "living in a reshaped reality" was identified, which depicted how changes in social participation and self-identity influenced ongoing experiences with TBI. Three main themes were generated: (1) "there's nothing that's the same" highlighted the daily challenges individuals faced post-injury, (2) "rebuilding and restarting" described how individuals with TBI navigated through their unfamiliar reality, and (3) "embrace it and run with it" explored participants' reactions towards life with a TBI. An explanatory model was developed, consisting of the overarching theme ("living in a reshaped reality") with the three integrated themes. Future research and clinical practices can build on this understanding to develop programmes to help individuals address their needs in post-injury life.

Investigations of Personality Trait in Subacute Post-Stroke Patients: Some Preliminary Observations

BACKGROUND AND OBJECTIVES

Personality change is an important psychiatric complication following stroke linked to severe affective dysregulation and behavioral alterations.

METHODS

We investigated personality traits in 20 patients (age 45.37 ± 13.41 years) with subacute stroke submitted to rehabilitation training within 1-3 months after a first-onset stroke. All patients underwent psychological evaluation by using the Personality Inventory for DSM-5 for adults (PID-5), a specific instrument that enables traits (dimensions and facets) to be assessed by providing a personality profile, and the Inventory of Interpersonal Problems 47 (IIP-47), a brief and valid self-report measure for screening personality disorders.

RESULTS

Personality change was identified by a positive correlation IIP-47 and PID-5 (r = 0.76; p = 0.03). Our patients, after a stroke, presented maladaptive personality traits associated with negative affect such as anxiety, emotional lability, and rigid perfectionism, and they reported interpersonal problems. These negative affective disorders correlated positively with cluster C personality disorders, including the avoidant, dependent, and obsessive compulsive personality disorders.

CONCLUSION

Preliminary results show personality changes in stroke survivors. The evaluation of personality changes could be useful to improve the management of the patient's behavioral alterations in a familiar environment and permit the possibility of prevention of psychological distress of the patients and their respective caregivers.

The experiences of wives following acquired brain injury (ABI). A qualitative analysis exploring realisations of change following the ABI of a "loved one."

The experiences of family members following Acquired Brain Injury (ABI) are well established, with spouses in particular facing multiple relational and personal changes. Qualitative studies have analysed accounts pertaining to a range of sequelae, however, "change" itself has yet to be addressed. This study explored the experiences of realisation of change for married women living with their husbands following ABI. Nine participants took part in semi-structured interviews focussing on becoming aware of changes in both their spouse and themselves post-injury. An Interpretative Phenomenological Analysis (IPA) was completed, arriving at two overarching themes; "bravery to face changes" and "lost and trapped in an unsolvable maze," with accompanying subthemes. Participants generally experienced realisation of change gradually, in some cases finding strategies to control their exposure to distress. They often referred to "acceptance," which held varied meanings, and metaphors appeared to aid personal meaning making. Relationship changes generated both dilemmas and the feeling of being trapped. Overall, this study contributes greater insights into the experiential mechanisms underpinning realisation of change in spouses after brain injury.

Brain-In-Hand technology for adults with acquired brain injury: A convergence of mixed methods findings

Introduction

Individuals with acquired brain injury may find it difficult to self-manage and live independently. Brain-in-Hand is a smartphone app designed to support psychological problems and encourage behaviour change, comprised of a structured diary, reminders, agreed solutions, and traffic light monitoring system.

Aim

To evaluate the potential use and effectiveness of Brain-in-Hand for self-management in adults with acquired brain injury.

Methods

A-B mixed-methods case-study design. Individuals with acquired brain injury ( n = 10) received Brain-in-Hand for up to 12 months. Measures of mood, independence, quality of life, cognition, fatigue, goal attainment, participation administered at baseline, 6 and 12 months. Semi-structured interviews conducted with acquired brain injury participants ( n = 9) and healthcare workers ( n = 3) at 6 months.

Results

Significant increase in goal attainment after 6 months use (t(7) = 4.20, p = .004). No significant improvement in other outcomes. Qualitative data suggested improvement in anxiety management. Contextual (personal/environmental) factors were key in influencing the use and effectiveness of Brain-in-Hand. Having sufficient insight, appropriate support and motivation facilitated use.

Conclusions

Brain-in-Hand shows potential to support acquired brain injury, but further work is required to determine its effectiveness. Context played a pivotal role in the effectiveness and sustained use of Brain-in-Hand, and needs to be explored to support implementation.

Personality changes after acquired brain injury and their effects on rehabilitation outcomes

Acquired brain injury (ABI) is often associated with personality changes. Pre- as well as post-injury personality traits are related to rehabilitation outcomes. However, it largely remains unclear whether post-injury personality shows any associations with rehabilitation outcomes over and above pre-injury personality. Using a case-control design, this study investigated (1) personality changes after ABI from patients' and significant others' perspective, and (2) relations of pre- and post-ABI personality traits to rehabilitation outcomes in the short- and long-term. 40 patients with ABI (85% stroke, 15% traumatic brain injury), 46 healthy controls and their significant others participated. Personality was assessed with NEO-FFI, rehabilitation outcomes (activities, participation, depression) were measured at two and ten months after ABI. Patient-ratings indicated decreases in extraversion and a trend towards reduced conscientiousness. Significant others reported increases in patients' neuroticism. Pre- as well as post-injury personality traits were associated with depression and activities at both short- and long-term timepoints after ABI. The association was strongest for long-term depressive symptoms where personality trait variables accounted for 49% of variance (Radjusted2). Our results confirm that ABI patients and significant others perceive personality changes, albeit in different dimensions. Pre- and post-ABI personality traits showed associations with rehabilitation outcomes, especially with emotional adjustment after the injury.

How does a narrative understanding of change in families post brain injury help us to humanise our professional practice?

In this paper, we critically explore the discourse of change post brain injury and challenge the dominant discourse of negative change, which alone leaves little room for other perspectives to exist. These negative changes pose a considerable risk to the well-being of families who may benefit from engaging in richer accounts making room for a more coherent and connected sense of self and family post-injury. We explore how narrative approaches provide opportunities for all practitioners to expand their professional scripts and support families to move towards a future which is not dominated by a discourse of loss. While loss and negative change is an important and very real consequence, of brain injury, focusing purely on stories of loss is life limiting for family members and can cause psychological distress. The life thread model is offered as a visible tool for all practitioners to engage with and use while working with families, providing a concrete focus for reflection and discussion of narratives relating to change which otherwise can feel quite abstract in everyday practice. We argue that one way we can humanise our professional practice is to support all practitioners to engage in a narrative understanding of family change following ABI.

A narrative review of biopsychosocial factors which impact overweight and obesity for individuals with acquired brain injury

Primary Objective: To discuss the biopsychosocial factors that affect being overweight or obese after acquired brain injury (ABI)Research Design: Narrative reviewMethods and Procedures: Based on the biopsychosocial model, we discuss the unique injury-specific factors that can affect bring overweight or obese among individuals with ABI including: (1) biological, (2) psychological and (3) social/ecological factors.Main Outcomes and Results: Injury-specific factors that impact being overweight or obese following ABI include endocrine dysfunction, pain, bowel and bladder incontinence, balance problems and motor impairment, medications, sleep quality and fatigue, alcohol and tobacco use, psychological disorders and symptoms, cognitive changes, social support, isolation, participation, transportation, independence, and knowledge. These factors may also compound general factors impacting weight management, making it difficult for individuals with ABI to maintain a healthy lifestyle.Conclusions: It is important to recognize the biopsychosocial factors that impact weight-loss and lifestyle change after ABI so that interventions can be tailored to meet individuals' unique needs. Empirical research is needed to better understand how biopsychosocial factors interact and impact overweight/ obesity after ABI.

The experience of families following traumatic brain injury in adult populations: A meta-synthesis of narrative structures

BACKGROUND

Traumatic brain injury has a significant effect on uninjured family members. Typically, this has been examined with a focus on psychopathological outcomes including stress, depression and anxiety. However, in recent years there has been increasing interest in the subjective experiences of families post-injury leading to a plethora of qualitative studies. Therefore, an in-depth examination and synthesis of this literature is now relevant and timely.

OBJECTIVE

To examine the subjective experiences of families following traumatic brain injury in adult populations in the sub/post-acute period through the synthesis of original qualitative research.

DESIGN

This paper presents a meta-synthesis using Thomas and Harden's framework of 'thematic synthesis' rooted in a critical realist philosophy.

DATA SOURCES

In July 2019 five electronic databases, were searched for the terms 'traumatic brain injury', 'family' and 'qualitative'. Studies were included if the primary research reported qualitative data about the subjective experiences of family members of adults with traumatic brain injury and had been published in a peer reviewed journal. Studies with mixed brain injury samples, child or adolescent traumatic brain injury or disorders of consciousness were excluded. Hand searching and citation searches were also completed.

REVIEW METHODS

Two reviewers screened titles, abstracts and full text and reached consensus through critical discussion. Thirty papers were finally agreed for inclusion in this review. Each study was then assessed for relevance, resonance and rigour using the Critical Appraisal Skills Programme (CASP) tool. Line by line coding of the findings in each paper was conducted as the basis for a thematic analysis and synthesis.

RESULTS

Descriptive themes were identified followed later by analytical themes. This final stage was informed by a narrative lens and from these, eight narrative functions belonging to four dimensions were identified from the subjective experiences of families post-traumatic brain injury. Specifically, these were: (1) Displacing and Anchoring; (2) Rupturing and Stabilising; (3) Isolating and Connecting; (4) Harming and Healing.

CONCLUSIONS

The interpretation of the narrative functions revealed the substantial existential work involved in negotiating lives, maintaining family system equilibrium and moving forward. As such, family members have their own unique narrative needs. Despite contemporary service models built around the injured person, service providers are well placed to support families in this everyday narrative work through actively attending to narrative structures and understanding the implications of these for family experience. The study protocol was registered with PROSPERO (International prospective register of systematic reviews) in July 2018 (Registration number: CRD42018085824). Tweetable abstract: This synthesis showed the immense and invisible work required for family members to maintain family system equilibrium and negotiate their lives post-TBI.

Experiences of inpatient rehabilitation from the perspective of persons with acquired brain injury

BACKGROUND

Perspectives of individuals with acquired brain injury (ABI) regarding inpatient rehabilitation experiences can inform patient-centered care; however, these voices are under-represented in the literature.

PURPOSE

To explore the experiences, needs, and preferences of patients from an ABI inpatient rehabilitation program in Ontario.

METHODS

Using an interpretive description approach, we interviewed 12 participants and analyzed the transcripts inductively to generate themes.

FINDINGS

We identified three major themes: (1) Life Rerouted - participants felt their lives diverted due to ABI, with rehabilitation seen as a way to return to pre-injury life, (2) Autonomy within Rehab highlighted the perceived importance of personal autonomy in decision-making within rehabilitation, and (3) Life (and Recovery) Go On reflected an ongoing recovery process after discharge - leading to mixed emotions. An overall message, "re-establishing personal identity is important to the recovery process," reflected theories of biographical disruption and relational autonomy.

IMPLICATIONS

Our findings provide a patient perspective for clinicians and administrators to consider. We found that ABI was significantly disruptive to personal identity - resulting in tensions in autonomy while attempting to reclaim a sense of identity. We suggest counseling services and strategies supporting post-injury adjustment, along with ways for rehabilitation professionals to enhance patient autonomy where possible.Implications for rehabilitationSustaining an ABI can significantly disrupt personal identity and sense of autonomy - especially as persons occupy the role of "patient" while in inpatient rehabilitation.Psychological support is recommended to address the impacts of ABI on patients' sense of identity, as well as on family members.Strategies of support might include, providing formal psychotherapy, as well as creating opportunities for patients and family members to discuss the changes they are experiencing, and to establish their personal narratives (e.g., through writing or art) or peer mentorship programs between discharged and current patients.Clinicians can enhance patient autonomy by increasing opportunities for communication with patients about choice; educating patients and family members on the rehabilitation team's decision-making process, and other methods that increase communication and provide consistent up-to-date information to patients and their family members.

In search of the 'self': Holistic rehabilitation in restoring cognition and recovering the 'self' following traumatic brain injury: A case report

BACKGROUND

Following mild-moderate traumatic brain injury (TBI), an individual experiences a range of emotional changes. It is often difficult for the patient to reconcile with their post-injury persona, and the memory of pre-injury personhood is particularly painful. Insight into one's cognitive deficits subsequent to injury can lead to an existential crisis and a sense of loss, including loss of self.

OBJECTIVE

Restoration of cognitive functions and reconciliation with loss of pre-traumatic personhood employing a holistic method of neuropsychological rehabilitation in a patient suffering from TBI.

METHODS

Ms. K.S, a 25-year-old female, presented with emotional disturbances following TBI. She reported both retrograde and anterograde amnesia. A multidimensional holistic rehabilitation was planned. Treatment addressed cognitive deficits through the basic functions approach. Cognitive behavioural methods for emotional regulation like diary writing helped reduce irritability and anger outbursts. Use of social media created new modes of memory activation and interactions. Compensatory strategies were used to recover lost skills, music-based attention training helped foster an individualised approach to the sense of one's body and self.

RESULTS

As a result of these differing strategies, changes were reflected in neuro-psychological tests, depression score and the patient's self-evaluation. This helped generate a coherent self-narrative.

CONCLUSION

Treatment challenges in such cases are increased due to patient's actual deficits caused by neuronal/biochemical changes. Innovative and multi-pronged rehabilitation strategies which involve everyday activities provided an answer to some of these problems. This method of rehabilitation may provide an optimistic context for future research.

Life is about "constant evolution": the experience of living with an acquired brain injury in individuals who report higher or lower posttraumatic growth

OBJECTIVE

To explore the experience of living with an Acquired Brain Injury (ABI) in individuals who report higher or lower posttraumatic growth (PTG).

METHOD

A multi-method design was employed. Participant scores on the Posttraumatic Growth Inventory (PTGI) were used to identify groups for qualitative comparative analysis. Individual semi-structured interviews were conducted with fourteen individuals with ABI. Data were analysed thematically.

RESULTS

Four themes emerged. The first two themes: "In my mind I was fine" surviving in aftermath of acquiring a brain injury and The everyday as "derailing" capture the transition process from an initial rehabilitation state characterised by neuropsychological and avoidance coping, towards active rebuilding for PTG. Internal building blocks for PTG and Growing in the social world: "you need to have that social connection" elaborate on the internal (e.g., acceptance, integration of the pre and post-injury self) and external (e.g., social relationships) factors seen to facilitate or obstruct PTG.

CONCLUSIONS

Under certain conditions, individuals living with ABI may construe positive growth from their experiences. Practitioners can support PTG development by providing individual and family-based supports aimed at increasing acceptance, the integration of self, and social connection throughout all stages of ABI rehabilitation.IMPLICATIONS FOR REHABILITATIONInternal factors such as having a flexible and positive mindset and external factors such as one's social environment can affect how individuals living with an ABI construe positive growth.Individuals with ABI and their families require access to individualised longitudinal support for neuropsychological and social challenges that can result in increased distress and obstruct the development of PTG.Efforts to facilitate acceptance and support the integration of the pre and post-injury self through recognition of continuity of self and processing of new schematic beliefs can benefit PTG development.Rehabilitation providers should support individuals with ABI to develop or maintain a positive social identity within new or existing social groups.

Patients' experiences and wellbeing after injury: A focus group study

Background

Injury can have physical, psychological and social consequences. It is unclear which factors have an impact on patients’ wellbeing after injury. This study aimed to explore, using focus groups, patients’ experiences and wellbeing after injury and which factors, impede or facilitate patients’ wellbeing.

Methods

Trauma patients, treated in the shock room of the Elisabeth-TweeSteden Hospital, the Netherlands, participated in focus groups. Purposive sampling was used. Exclusion criteria were younger than 18 years old, severe traumatic brain injury, dementia, and insufficient knowledge of the Dutch language. The interviews were recorded, transcribed verbatim, and analyzed using coding technique open, axial, and selective coding, based on phenomenological approach.

Results

Six focus groups (3 to 7 participants) were held before data saturation was reached. In total, 134 patients were invited, 28 (21%) agreed to participate (Median age: 59.5; min. 18 –max. 84). Main reasons to decline were fear that the discussion would be too confronting or patients experienced no problems regarding the trauma or treatment. Participants experienced difficulties on physical (no recovery to pre-trauma level), psychological (fear of dying or for permanent limitations, symptoms of posttraumatic stress disorder, cognitive dysfunction), social (impact on relatives and social support) wellbeing. These are impeding factors for recovery. However, good communication, especially clarity about the injury and expectations concerning recovery and future perspectives could help patients in surrendering to care. Patients felt less helpless when they knew what to expect.

Conclusions

This is the first study that explored patients’ experiences and wellbeing after injury. Patients reported that their injury had an impact on their physical, psychological, and social wellbeing up to 12 months after injury. Professionals with the knowledge of consequences after injury could improve their anticipation on patients’ need.

The man who used to shrug - one man's lived experience of TBI

BACKGROUND

Stress is common to the experience of TBI. Stressors challenge physical and psychological coping abilities and undermine wellbeing. Brain injury constitutes a specific chronic stressor. An issue that hinders the usefulness of a stress-based approach to brain injury is a lack of semantic clarity attaching to the term stress. A more precise conceptualisation of stress that embraces experienced uncertainty is allostasis.

OBJECTIVE

An emerging body of research, collectively identifiable as 'the social cure' literature, shows that the groups that people belong to can promote adjustment, coping, and well-being amongst individuals confronted with injuries, illnesses, traumas, and stressors. The idea is deceptively simple, yet extraordinarily useful: the sense of self that individuals derive from belonging to social groups plays a key role in determining health and well-being. The objective of this research was to apply a social cure perspective to a consideration of an individual's lived experience of TBI.

METHODS

In a novel application of interpretative phenomenological analysis (IPA) this research has investigated one person's lived experience in a single case study of traumatic brain injury.

RESULTS

Paradox, shifting perspectives and self under stress, linked by uncertainty, were the themes identified.

CONCLUSIONS

A relational approach must be key to TBI rehabilitation.

Clinical Approach to Personality Change Due to Another Medical Condition

BACKGROUND

Medical personality change (MPC) is a codable diagnosis (i.e., F07.0) that deserves consideration when a patient is inexplicably no longer "acting like him/herself." Its presentation ranges from subtle to severe and is often characterized by bafflingly poor judgment and impairment in several aspects of a person's life. Despite the global impact that MPC can have on a patient's functioning, occupation, and relationships, this condition receives far less clinical consideration than better known syndromes such as depression or anxiety and is often likely incorrectly formulated as such.

OBJECTIVE/METHODS

This article provides a clinically focused review of MPC. We review its clinical assessment followed by a review of its subtypes, which we have categorized to reflect the behavioral correlates of known frontotemporal-subcortical circuits. These include the apathetic type (ventromedial prefrontal cortex), the labile and disinhibited types (orbitofrontal cortex), and the aggressive and paranoid types (medial temporal lobes).

RESULTS

For each of these 3 categories, we describe the clinical presentation and review management strategies. For each category, we focus on 3 common causes for MPC-traumatic brain injury, Huntington disease, and brain tumors-which we have selected because clinical features of MPC due to these conditions generalize to many other etiologies of MPC.

CONCLUSIONS

MPC warrants clinical attention for the range of dysfunction and distress it can cause. It also deserves further scientific study to better characterize its phenotypes, to tailor instruments for its clinical assessment, and to identify effective treatments.

What is the functional/organic distinction actually doing in psychiatry and neurology?

The functional-organic distinction aims to distinguish symptoms, signs, and syndromes that can be explained by diagnosable biological changes, from those that cannot. The distinction is central to clinical practice and is a key organising principle in diagnostic systems. Following a pragmatist approach that examines meaning through use, we examine how the functional-organic distinction is deployed and conceptualised in psychiatry and neurology. We note that the conceptual scope of the terms 'functional' and 'organic' varies considerably by context. Techniques for differentially diagnosing 'functional' and 'organic' diverge in the strength of evidence they produce as a necessary function of the syndrome in question. Clinicians do not agree on the meaning of the terms and report using them strategically. The distinction often relies on an implied model of 'zero sum' causality and encourages classification of syndromes into discrete 'functional' and 'organic' versions. Although this clearly applies in some instances, this is often in contrast to our best scientific understanding of neuropsychiatric disorders as arising from a dynamic interaction between personal, social and neuropathological factors. We also note 'functional' and 'organic' have loaded social meanings, creating the potential for social disempowerment. Given this, we argue for a better understanding of how strategic simplification and complex scientific reality limit each other in neuropsychiatric thinking. We also note that the contribution of people who experience the interaction between 'functional' and 'organic' factors has rarely informed the validity of this distinction and the dilemmas arising from it, and we highlight this as a research priority.

The unidimensionality of the five Brain Injury Rehabilitation Trust Personality Questionnaires (BIRT-PQs) may be improved: preliminary evidence from classical psychometrics

Objective: To assess the internal construct validity (ICV) of the five Brain Injury Rehabilitation Trust Personality Questionnaires (BIRT-PQ) with Classical Test Theory methods.Methods: Multicenter cross-sectional study involving 11 Italian rehabilitation centers. BIRT-PQs were administered to patients with severe Acquired Brain Injury and their respective caregivers. ICV was assessed by the mean of an internal consistency analysis (ICA) and a Confirmatory Factor Analysis (CFA).Results: Data from 154 patients and their respective caregivers were pooled, giving a total sample of 308 subjects. Despite good overall values (alphas ranging from 0.811 to 0.937), the ICA revealed that several items within each scale did not contribute as expected to the total score. This result was confirmed by the CFA, which showed the misfit of the data to a unidimensional model (RMSEA ranging from 0.077 to 0.097). However, after accounting for local dependency found within the data, fitness to a unidimensional model improved significantly (RMSEA ranging from 0.050 to 0.062).Conclusion: Despite some limitations, our analyses demonstrated the lack of ICV for the BIRT-PQ total scores. It is envisaged that a more comprehensive ICV analysis will be performed with Rasch analysis, aiming to improve both the measurement properties and the administrative burden of each BIRT-PQ.

Traumatic brain injury-needs and treatment options in the chronic phase: Study protocol for a randomized controlled community-based intervention

BACKGROUND

Traumatic brain injury (TBI) is often associated with life-long medical, cognitive, emotional, and behavioral changes. Although long-lasting disabilities are expected, research on effective treatment options in the chronic phase of TBI is scarce.

METHODS/DESIGN

This study protocol describes a randomized controlled trial (RCT) aimed at evaluating the effectiveness of a goal-oriented and community-based intervention for increasing community integration, quality of life, and functional independence in the chronic phase of complicated mild to severe TBI. Participants will be recruited from Oslo University Hospital, Norway. Patients aged 18-72 years living at home with MRI/CT-verified intracranial abnormalities, a TBI diagnosis, a time since injury of ≥ 2 years, and who experience either current TBI-related problems or restrictions in community integration will be included. The 120 participants will be randomized 1:1 to either (a) an intervention group, which will receive an in-home intervention program over 4 months, or (b) a control group receiving standard care in the municipalities. The intervention will consist of six home visits and two telephone contacts with a rehabilitation professional. A SMART-goal approach will be adopted to target the individual's self-reported TBI difficulties in everyday life. Primary outcomes will be self-reported quality of life and participation. Secondary outcomes include symptom burden, emotional functioning, and clinician-assessed global outcome and need for rehabilitation services. Outcomes will be evaluated at baseline and 4-5 and 12 months after baseline. Caregiver burden and general health will be assessed in participating family members. Goal attainment and acceptability will be evaluated in the intervention group. A process evaluation will be carried out to evaluate protocol adherence, and a cost-effectiveness analysis will be applied if the intervention is found to be effective.

DISCUSSION

The current study provides an innovative approach to rehabilitation in the chronic phase of TBI evaluated using an RCT design that may inform treatment planning, health policies, and coordination of patient care. Further, the study may demonstrate new modes of establishing collaboration and knowledge transition between specialized rehabilitation facilities and local rehabilitation services that may improve patient outcomes.

Exploring self-concept, wellbeing and distress in therapeutic songwriting participants following acquired brain injury: A case series analysis

Acquired brain injury (ABI) presents a significant threat to sense of self and necessitates a complex process of psychosocial adjustment. Self-concept changes remain understudied in the early stages of inpatient rehabilitation. The aim of the current study was to examine changes in self-concept, distress, wellbeing and functional skills for five inpatients undertaking a music therapy intervention within a subacute rehabilitation centre in Victoria, Australia. Participants completed a six-week, 12-session therapeutic songwriting programme to produce past-, current- and future-self-focused songs. A range of self-concept, subjective wellbeing and distress measures were completed pre-, mid- and post-intervention. A descriptive case series approach was applied to determine trends in pre-post scores for five individual cases. Participants showing the greatest gains across self-concept and subjective wellbeing indices also showed the greatest functional gains on the Functional Independence Measure (FIM) from admission to discharge. The current study highlights the importance of examining early changes in self-concept, wellbeing and distress in subacute rehabilitation, and suggests that individualised songwriting programmes warrant further research attention in neurological populations.

The relationship between stroke survivors' perceived identity and mood, self-esteem and quality of life

OBJECTIVES

To examine change in identity after stroke and to elucidate its relationship with mood and quality of life. To test Higgins' theory of the impact of identity (self-discrepancy) on anxiety and depression. To examine the role of self-esteem in mediating the relationship between identity and outcomes.

METHOD

Sixty-five community-living first-time stroke survivors, mean age 61.58 and time since stroke 5.60 years, were recruited from stroke charities. A cross-sectional study used the Head Injury Semantic Differential Scale, the Hospital Anxiety and Depression Scale, the Rosenberg Self-Esteem Scale, the Stroke-Specific Quality of Life Questionnaire (adapted) and the Barthel Index.

RESULTS

Identity was rated more negatively after stroke than before (t(64) = 6.46, p < .00). Greater discrepancy in identity was associated with anxiety (r = .38, p < .00), depression (r = .59, p < .00), self-esteem (r = -.48, p < .00) and quality of life (r = -.54, p < .00). Overall positivity of identity after stroke predicted outcomes even better than discrepancy. The association between discrepancy and mood and quality of life was mediated by self-esteem (β = .30, p < .01; β = -.24, p < .01, respectively). Specific types of discrepancy defined by Higgins did not show differential relationships with anxiety and depression as predicted.

CONCLUSIONS

Identity changes after stroke and identity and self-esteem are associated with important outcomes for stroke survivors.

Exploration of correlates of self-reported personality change after moderate-severe traumatic brain injury

OBJECTIVE

Individuals with traumatic brain injury (TBI) often express concern that their personality has changed. Factors generating that conclusion are rarely explored quantitatively. Accordingly, this study examines neurobehavioural correlates of self-reported personality change.

METHODS

Seventy-one participants and informants were interviewed M = 57.9 (SD = 46.9) months after a moderate-severe TBI. The degree of self-reported personality change was correlated with scores on measures of general cognitive functioning, executive functioning, olfaction, social-emotional behaviour, emotional distress and the Expressed Emotion close informants directed towards them.

RESULTS

As expected, self-reported personality change correlated with dysexecutive symptoms and depression. Although anosmia (a putative index of ventral frontal damage) correlated with reduced self-reported emotional recognition and empathy, against prediction, the latter measures did not correlate with self-reported personality change. Neither were the predicted positive correlations found between high Expressed Emotion (criticism and emotional over-involvement) and self-reported personality change.

DISCUSSION

These findings are discussed in the context of previous work. A need to replicate and extend the present findings is suggested. A strategy to further clarify the relationships perceived personality change have with (a) self-reported change in specific behaviours and (b) identity change is advocated. Implications for intervention are suggested.

Evidence of Big-Five personality changes following acquired brain injury from a prospective longitudinal investigation

OBJECTIVE

Many studies using different assessment methods have reported personality changes after acquired brain injury (ABI). However, to our knowledge, no prospective study has yet been conducted to examine whether previous cross-sectional and retrospective results can be replicated in a longitudinal prospective design. Further, because clinical control groups were only rarely used, it remains debatable if the personality changes found are unique to patients with ABI or if they also affect patients with other disabilities.

METHODS

This study examined personality change in 114 participants with different kinds of ABI, 1321 matched controls (general control, GC), and 746 matched participants with restrictive impairments other than brain injury (clinical control, CC) in a prospective longitudinal design using data from the panel survey Household, Income and Labour Dynamics in Australia (HILDA).

RESULTS

Participants with ABI showed significantly larger declines in Extraversion and Conscientiousness compared with the GC group. When the ABI participants were compared with the CC group, only the difference in Conscientiousness remained significant.

CONCLUSION

Our prospective data corroborate evidence from previous cross-sectional studies that patients with ABI experience larger declines in Extraversion and Conscientiousness than the general population. Whereas the effect on Conscientiousness was unique to patients with ABI, the decline in Extraversion was also observed in participants with other impairments.

Are Mental Disorders Brain Diseases, and What Does This Mean? A Clinical-Neuropsychological Perspective

Neuroscientific research has substantially increased our knowledge about mental disorders in recent years. Along with these benefits, radical postulates have been articulated according to which understanding and treatment of mental disorders should generally be based on biological terms, such as neurons/brain areas, transmitters, genes etc. Proponents of such a 'biological psychiatry' claim that mental disorders are analogous to neurological disorders and refer to neurology and neuropsychology to corroborate their claims. The present article argues that, from a clinical-neuropsychological perspective, 'biological psychiatry' is based on a mechanistic, 'cerebrocentric' framework of brain (dys-)function which has its roots in experimental neuroscience but runs up against narrow limits in clinical neurology and neuropsychology. In fact, understanding and treating neurological disorders generally demands a systems perspective including brain, organism and environment as intrinsically entangled. In this way, 'biological' characterizes a 'holistic', nonreductionist level of explanation, according to which the significance of particular mechanisms can only be estimated in the context of the organism (or person). This is evident in the common observation that local brain damage does not just lead to an isolated loss of function, but to multiple attempts of reorganization and readaptation; it initiates new developments. Furthermore, treating brain disorders necessarily includes aspects of individuality and subjectivity, a conclusion that contradicts the purely 'objectivist', third-person stance put forward by some proponents of biological psychiatry. In sum, understanding and treating brain damage sequelae in the clinical neurosciences demands a biopsychosocial perspective, for both conceptual and historical reasons. The same may hold for psychiatry when adopting a brain-based view on mental disorders. In such a perspective, biological psychiatry seems an interesting project but falls short of its original claims.

How Partners Experience Personality Change After Traumatic Brain Injury – Its Impact on Their Emotions and their Relationship

Objective: The aim of this qualitative study was to explore how spouses/partners experience social, emotional and behavioural changes in persons following traumatic brain injury (TBI), with a particular focus on their emotional impact and the effect on the couple relationship.

Method: Interpretative phenomenological analysis (IPA) of interview data explored five women's experiences of these changes in their partners following TBI.

Results: Themes describe the direct emotional impact of living with the changes as well as the emotional impact of attempts to manage and make sense of the changes (identity change, managing the changes and making sense of the changes). The impact on the couple relationship is described under the themes of feeling love and receiving love. Changes led three of the participants to experience their partner as having been replaced by a new person; they actively disliked this new person; they felt unable to love the new person in the same way as the old person; and their love was defined in terms of a caring relationship, rather than a spousal relationship.

Conclusions: The study provides insight into why social, emotional and behavioural changes might be so consistently associated with reduced emotional wellbeing and lower levels of relationship quality and satisfaction.

The Italian version of the Brain Injury Rehabilitation Trust (BIRT) personality questionnaires: five new measures of personality change after acquired brain injury

The aim of this study was to describe the translation and adaptation of the BIRT personality questionnaires for the Italian population. This included the replication of validity testing and the collection of normative data. Following translation and adaptation according to cross-cultural guidelines, the questionnaires were administered as a pre-test to a sample of 20 healthy subjects and then to 10 patients. The questionnaires were then administered to 120 healthy subjects equally distributed by sex, education, and age, to collect normative data from an Italian population. The questionnaires were easily administered to both healthy subjects and patients. Statistical analysis on normative data was conducted to find the mean value for each questionnaire. This study lays the foundations for using a new instrument to assess behavioral changes after acquired brain injury on the Italian population.

Affiliative and "self-as-doer" identities: Relationships between social identity, social support, and emotional status amongst survivors of acquired brain injury (ABI)

Social support is an important factor in rehabilitation following acquired brain injury (ABI). Research indicates that social identity makes social support possible and that social identity is made possible by social support. In order to further investigate the reciprocity between social identity and social support, the present research applied the concepts of affiliative and "self-as-doer" identities to an analysis of relationships between social identity, social support, and emotional status amongst a cohort of 53 adult survivors of ABI engaged in post-acute community neurorehabilitation. Path analysis was used to test a hypothesised mediated model whereby affiliative identities have a significant indirect relationship with emotional status via social support and self-as-doer identification. Results support the hypothesised model. Evidence supports an "upward spiral" between social identity and social support such that affiliative identity makes social support possible and social support drives self-as-doer identity. Our discussion emphasises the importance of identity characteristics to social support, and to emotional status, for those living with ABI.

Self-Reflective Meaning Making in Troubled Times: Change in Self-Identity After Traumatic Brain Injury

Our aim with this article is to clarify the concept of change in self-identity following traumatic brain injury (TBI). We used concept analysis methodology-predominantly concept clarification. We identified 110 articles using a systematic literature search, and used critical appraisal, content analysis, and analytical questioning to explore attributes and boundaries. A reported change in self-identity is the ultimate expression of a variety of cognitive, psychological, and social sequelae of TBI. We present an integrative model of this process, identifying three potential levels of change: (a) component parts (egocentric self, sociocentric self, and "identity as shared with others"); (b) integral processes (self-awareness and expression via meaningful occupation and narratives); and (c) whole-system disruption. Change in self-identity after TBI is a highly individualistic process. The driver of this process is "self-reflective meaning making," giving a purpose and direction in life, providing motivation and goals for future behavior.

How cognitive neuroscience could be more biological-and what it might learn from clinical neuropsychology

Three widespread assumptions of Cognitive-affective Neuroscience are discussed: first, mental functions are assumed to be localized in circumscribed brain areas which can be exactly determined, at least in principle (localizationism). Second, this assumption is associated with the more general claim that these functions (and dysfunctions, such as in neurological or mental diseases) are somehow generated inside the brain (internalism). Third, these functions are seen to be “biological” in the sense that they can be decomposed and finally explained on the basis of elementary biological causes (i.e., genetic, molecular, neurophysiological etc.), causes that can be identified by experimental methods as the gold standard (isolationism). Clinical neuropsychology is widely assumed to support these tenets. However, by making reference to the ideas of Kurt Goldstein (1878–1965), one of its most important founders, I argue that none of these assumptions is sufficiently supported. From the perspective of a clinical-neuropsychological practitioner, assessing and treating brain damage sequelae reveals a quite different picture of the brain as well as of us “brain carriers”, making the organism (or person) in its specific environment the crucial reference point. This conclusion can be further elaborated: all experimental and clinical research on humans presupposes the notion of a situated, reflecting, and interacting subject, which precedes all kinds of scientific decomposition, however useful. These implications support the core assumptions of the embodiment approach to brain and mind, and, as I argue, Goldstein and his clinical-neuropsychological observations are part of its very origin, for both theoretical and historical reasons.

Establishing a person-centred framework of self-identity after traumatic brain injury: a grounded theory study to inform measure development

OBJECTIVE

To develop a theoretically sound, client-derived framework to underpin development of a measure reflecting the impact of traumatic brain injury (TBI) on a person's self-identity.

DESIGN

Grounded theory, based on transcription of audio recordings from focus group meetings with people who have experienced TBI, analysed with constant comparative methods.

SETTING

8 different urban and rural communities in New Zealand.

PARTICIPANTS

49 people (34 men, 15 women), 6 months to 36 years after mild-to-severe TBI.

RESULTS

The central concept emerging from the data was that of desiring to be or having lost a sense of being an integrated and valued person. The three main subthemes were: (1) having a coherent, satisfying and complete sense of oneself, (2) respect, validation and acceptance by others and (3) having a valued place in the world.

CONCLUSIONS

This study reinforces the notion that change in self-identity is an important aspect of life after TBI, and provides information on what this concept means to people with TBI. In order to scientifically evaluate relationships between self-identity and other aspects of health (eg, depression, quality of life), and to test the effect of interventions to address problems with self-identity after TBI, a quantitative tool for evaluation of this construct is required. Themes from this research provide a foundation for the development of a measure of self-identity grounded in the language and experience of people with TBI.

Changes in personality after mild traumatic brain injury from primary blast vs. blunt forces

INTRODUCTION

Injuries from explosive devices can cause blast-force injuries, including mild traumatic brain injury (mTBI).

OBJECTIVE

This study investigated changes in personality from blast-force mTBI in comparison to blunt-force mTBI.

METHODS

Clinicians and significant others assessed US veterans who sustained pure blast-force mTBI (n = 12), as compared to those who sustained pure blunt-force mTBI (n = 12). Inclusion criteria included absence of any mixed blast-blunt trauma and absence of post-traumatic stress disorder. Measures included the Interpersonal Measure of Psychopathy (IM-P), the Big Five Inventory (BFI), the Interpersonal Adjectives Scale (IAS) and the Frontal Systems Behaviour Scale (FrSBe).

RESULTS

There were no group differences on demographic or TBI-related variables. Compared to the Blunt Group, the Blast Group had more psychopathy on the IM-P, with anger, frustration, toughness and boundary violations and tended to more neuroticism on the BFI. When pre-TBI and post-TBI assessments were compared on the IAS and FrSBe, only the patients with blast force mTBI had become more cold-hearted, aloof-introverted and apathetic.

CONCLUSION

These results suggest that blast forces alone can cause negativistic behavioural changes when evaluated with selected measures of personality. Further research on isolated blast-force mTBI should focus on these personality changes and their relationship to blast over-pressure.

Neurobehavioral disorders

Neurobehavioral disorders are composed of a large group of behavioral impairments seen in association with brain disease (e.g., stroke, multiple sclerosis, dementia, and neuro-oncological conditions), transient as well as permanent brain impairments (e.g., metabolic and toxic encephalopathies), and/or injury (e.g., trauma, hypoxia, and/or ischemia). The neurorehabilitative assessment and management of such disorders is often poorly addressed in the context of overall neurological, psychiatric, and rehabilitative care. Too often, more basic, yet critical, aspects of behavioral assessment and treatment are not addressed or only superficially addressed by evaluating clinicians. Physicians often overly rely on pharmacological interventions as initial and/or sole treatment approaches rather than taking a pragmatic biopsychosocial approach that focuses on holistic disease state management. This chapter provides readers with an overview of the common behavioral impairments associated with brain dysfunction due to disease, injury, or toxicity. Details regarding the nature of impairments such as localization-related syndromes, affective disorders and personality disorders, among others are expounded. Principles of neurobehavioral assessment and treatment are examined including general guidelines for eliciting a history and physical, behavioral analysis, and functional behavioral assessment. General treatment caveats are provided including discussion of impairment and disability adaptation, and creation of positive behavioral supports. The topic of pharmacological management of neurobehavioral disorders is covered in numerous other references including Chapter 33 of this text.

Acquired brain injury: combining social psychological and neuropsychological perspectives

This theoretical paper reviews an emerging literature which attempts to bring together an important area of social psychology and neuropsychology. The paper presents a rationale for the integration of the social identity and clinical neuropsychological approaches in the study of acquired brain injury (ABI). The paper begins by reviewing the social and neuropsychological perspectives of ABI. Subsequently, theoretical and empirical studies that demonstrate the social influences on neuropsychology and the inherently social nature of mind are considered. Neuropsychological understandings of social identities and their potential relationships to the variability in ABIs are also discussed. The values of these understandings to ABI rehabilitation are then examined. The paper concludes by suggesting an agenda for future research that integrates the social identity and neuropsychological paradigms so that psychology might grow in its store of applicable knowledge to enhance support and rehabilitation for those with ABI.

Morphological and genetic activation of microglia after diffuse traumatic brain injury in the rat

Traumatic brain injury (TBI) survivors experience long-term post-traumatic morbidities. In diffuse brain-injured rats, a chronic sensory sensitivity to whisker stimulation models the agitation of TBI survivors and provides anatomical landmarks across the whisker-barrel circuit to evaluate post-traumatic neuropathology. As a consequence of TBI, acute and chronic microglial activation can contribute to degenerative and reparative events underlying post-traumatic morbidity. Here we hypothesize that a temporal sequence of microglial activation states contributes to the circuit pathology responsible for post-traumatic morbidity, and test the hypothesis by examining microglial morphological activation and neuroinflammatory markers for activation states through gene expression and receptor-binding affinity. Adult male, Sprague-Dawley rats were subjected to a single moderate midline fluid percussion injury (FPI) or sham injury. Microglial activation was determined by immunohistochemistry, quantitative real-time PCR and receptor autoradiography in the primary somatosensory barrel field (S1BF) and ventral posterior medial nucleus (VPM) of the thalamus at 7 and 28 days following FPI. Morphological changes indicative of microglial activation, including swollen cell body with thicker, shrunken processes, were evident in S1BF and VPM at 7 and 28 days post-injury. Principally at 7 days post-injury in VPM, general inflammatory gene expression (major histocompatibility complex I, major histocompatibility complex II, translocator protein 18 kDa [TSPO]) is increased above sham level and TSPO gene expression confirmed by receptor autoradiography. Further, CD45, a marker of classical activation, and TGF-βI, an acquired deactivation marker, were elevated significantly above sham at 7 days post-injury. Daily administration of the anti-inflammatory ibuprofen (20mg/kg, i.p.) significantly reduced the expression of these genes. Evidence for alternative activation (arginase 1) was not observed. Thus, these data demonstrate concomitant classical activation and acquired deactivation phenotypes of microglia in diffuse TBI in the absence of overt contusion or cavitation. Anti-inflammatory treatment may further alleviate the neuropathological burden of post-traumatic inflammation.

Neuropsychiatric complications of traumatic brain injury

Traumatic brain injury (TBI) may be defined as any extracranial mechanical force to the brain that results in any period of loss of consciousness, any loss of memory for events immediately before or after the event, or any alteration in mental status at the time of the event. The major causes are automobile accidents, falls, sporting injuries, and assaults. Many soldiers returning from combat in Afghanistan and Iraq have also experienced TBI. This article provides an overview of the neuropsychiatric complications of TBI, including impairment of consciousness, posttraumatic amnesia, cognitive disorders and dementia, posttraumatic epilepsy, aphasia, depression, mania, psychosis, anxiety disorders, personality changes, aggression, behavioral dyscontrol, fatigue/apathy, and increased risk of suicide. Discussion will focus primarily on issues affecting mental health clinicians. Because mental health providers are more involved in care of chronic issues related to TBI, these issues will be discussed in more detail, although acute neuropsychiatric complications of TBI will be briefly explained.

Selbstkonzept nach erworbenen Hirnschädigungen: Veränderungen der Selbstwahrnehmung und Subjektives Wohlbefinden

Negative Selbstkonzepte stehen in Zusammenhang zu erhöhter depressiver Symptomatik, vermehrter psychosozialer Belastung und reduzierter Lebensqualität, was ihre Relevanz für Rehabilitationsprozesse begründet. Untersucht wurden Selbstkonzeptveränderungen nach erworbenen Hirnschädigungen bei PatientInnen der akuten (N = 59) und postakuten (N = 29) Rehabilitationsphase. Beide Stichproben bewerten aktuelle Selbstkonzepte verglichen mit prämorbiden Einschätzungen negativ. Faktorenanalytisch wurden 2 Selbstkonzeptbereiche ermittelt („Emotionales Erleben“, „Eigenschaften in sozialen Interaktionen“), die von der Erkrankung unterschiedlich stark betroffen sind. Negative aktuelle Selbstkonzepte stehen in engem Zusammenhang zu reduziertem Subjektivem Wohlbefinden und erklären regressionsanalytisch einen substantiellen Varianzanteil des Subjektiven Wohlbefindens. Soziodemographische und schädigungsbezogene Variablen spielen demgegenüber eine untergeordnete Rolle. Die Ergebnisse sprechen für die Berücksichtigung von Interventionen zur positiven Beeinflussung des Selbstkonzeptes in der psychotherapeutischen Behandlung von PatientInnen mit erworbenen Hirnschädigungen.
