Effects of computerized cognitive training on cognitive function, activity, and participation in individuals with stroke: A randomized controlled trial

BACKGROUND: Computerized cognitive training (CCT) is an emerging alternative intervention for stroke survivors. OBJECTIVE: This study investigated the effects of CCT on the cognition, activity, and participation of stroke survivors and compared the findings with those of match-dosed conventional cognitive training. METHODS: This randomized controlled trial included 39 patients with stroke who were divided into the intervention group (n = 19; receiving CCT with Lumosity software) and the control group (n = 20; receiving conventional cognitive training). Both the groups were trained for 20 min, twice a week, for 12 weeks. Participants were evaluated at pretest, posttest, and 4-week follow-up. Outcome measures included various cognitive function tests and the Stroke Impact Scale scores. RESULTS: The CCT group exhibited significant improvement in global cognitive function (evaluated using the Mini-Mental State Examination and Montreal Cognitive Assessment) and specific cognitive domains: verbal working memory (backward digit span test), processing speed (Symbol Digit Modalities Test), and three MoCA subtests (attention, naming, and delayed recall). CCT exerted no significant effect on activities and participation. No significant between-group differences in changes in cognitive function were noted. However, CCT significantly improved cognitive function domains immediately after training, and these effects were sustained at the 4-week follow-up. CONCLUSIONS: Cognitive function of individuals with chronic stroke could improve after administration of CCT. However, future studies with a more rigorous design and higher training dose are warranted to validate our findings.

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.

Good things better? Reappraisal and discrete emotions in acquired brain injury

There has been substantial interest in emotion after acquired brain injury (ABI), but less attention paid to emotion regulation (ER). Research has focused primarily on the ER strategy of reappraisal for regulating negative emotions, without distinguishing between classes of emotion, and there has been no attempt at exploring these differences in patients with ABI. The present study explored components of reappraisal, across classes of emotion, and their associated neuropsychological mechanisms. Thirty-five patients with ABI and twenty-two matched healthy control participants (HCs) completed two questionnaires, a battery of cognitive tasks, and an emotion regulation task (the Affective Story Recall Reappraisal task). Results suggest that those with ABI take longer, and generate fewer reappraisals than HCs across several discrete emotions. Notably, their ability to decrease emotional intensity did not differ significantly to HCs for negative emotions, but findings suggest that their reappraisals are less effective when up-regulating neutral emotions to positive. Working memory was the only significant predictor of the total number of reappraisals generated, and the time taken to produce a first reappraisal. Implications of these findings are discussed in the context of neuropsychological rehabilitation, including the role of the relatives in implementing and reinforcing micro-interventions.

Meaning Making Process and Recovery Journeys Explored Through Songwriting in Early Neurorehabilitation: Exploring the Perspectives of Participants of Their Self-Composed Songs Through the Interpretative Phenomenological Analysis

Objectives: This pilot study examined how 15 participants in early rehabilitation described their self-composed Songs 6- to 12-months following participation in a 6-week identity-focused songwriting program. Specific focus was given to the process of meaning making and identity reconstruction in the participants’ self-composed songs.

Methods: Data were collected through individual semi-structured interviews (n = 15) and analyzed using interpretative phenomenological analysis. Findings were developed idiographically as super-ordinate themes unique to each participant, then analyzed across cases to identify recurrent themes and subthemes.

Results: Participants described the songwriting process as taking them through one of four distinct recovery journeys described by individuals following acquired neurodisability who underwent a focused therapeutic songwriting program. These included (1) re-conceptualizing values and shifting perspectives about self (my body is broken but my mind has been set free); (2) recognizing acquired inner resources to negotiate discrepancies in self (hope is there); (3) confirming existing values and identifying resources and coping strategies (I have what I need to move forward); (4) confirming previously held values and ongoing process of negotiating discrepancies in self (I don’t yet have the answers).

Conclusion: The current study provides insight into the nature and process of meaning making and recovery journeys perceived by individuals with neurodisability. Our findings suggest that songwriting could be a therapeutic tool to facilitate identity reconstruction in neurorehabilitation.

Examining the relationship and clinical management between traumatic brain injury and pain in military and civilian populations

In this review, we discuss the comorbidity of traumatic brain injury (TBI) and pain among civilians and military members, the common causes of pain resulting from TBI, and offer insight about the therapeutic management of TBI symptoms and pain. Traumatic brain injury (TBI) is a debilitating health problem and one of the most common post-TBI symptoms is pain, which can contribute to psychological issues such as Post-traumatic stress disorder (PTSD) and depression. Headache pain appears to be the most common type of pain that results from TBI, yet pain can also be more widespread. Managing TBI symptoms and pain simultaneously is difficult because extensive randomized control and clinical studies assessing the effectiveness of therapeutic approaches are lacking. Pharmacological agents such as antidepressants and Triptans and nonpharmacological therapies such as cognitive rehabilitation and physical therapies are commonly used yet it is unknown how effective these therapies are in the long-term. A combination of pharmacological and non-pharmacological therapies is often more effective for managing TBI symptoms and pain than either treatment alone. However, future research is needed to determine the most therapeutic approaches for managing the comorbidity of pain and TBI symptoms in the long term. This review offers suggestions for such future studies.

Cognitive rehabilitation: assessment and treatment of persistent memory impairments following ECT

Few tests address the types of memory problem commonly reported after electroconvulsive therapy (ECT). Here, we focus on the importance of neuropsychological assessment in ECT-treated patients and describe a number of tasks that may be useful in measuring the everyday memory problems of such patients with ongoing memory difficulties. At the time of writing, no attempts have been made to rehabilitate patients who experience persistent adverse cognitive effects, but clinicians should be aware of the potential beneficial role of cognitive rehabilitation in the treatment and management of these effects.

A narrative literature review of depression following traumatic brain injury: prevalence, impact, and management challenges

Depression is one of the most common conditions to emerge after traumatic brain injury (TBI), and despite its potentially serious consequences it remains undertreated. Treatment for post-traumatic depression (PTD) is complicated due to the multifactorial etiology of PTD, ranging from biological pathways to psychosocial adjustment. Identifying the unique, personalized factors contributing to the development of PTD could improve long-term treatment and management for individuals with TBI. The purpose of this narrative literature review was to summarize the prevalence and impact of PTD among those with moderate to severe TBI and to discuss current challenges in its management. Overall, PTD has an estimated point prevalence of 30%, with 50% of individuals with moderate to severe TBI experiencing an episode of PTD in the first year after injury alone. PTD has significant implications for health, leading to more hospitalizations and greater caregiver burden, for participation, reducing rates of return to work and affecting social relationships, and for quality of life. PTD may develop directly or indirectly as a result of biological changes after injury, most notably post-injury inflammation, or through psychological and psychosocial factors, including pre injury personal characteristics and post-injury adjustment to disability. Current evidence for effective treatments is limited, although the strongest evidence supports antidepressants and cognitive behavioral interventions. More personalized approaches to treatment and further research into unique therapy combinations may improve the management of PTD and improve the health, functioning, and quality of life for individuals with TBI.

Impact of the Brain Injury Family Intervention (BIFI) training on rehabilitation providers: A mixed methods study

BACKGROUND

The psychological impact of TBI is vast, leading to adverse effects on survivors and their caregivers. Unhealthy family functioning may be mitigated by therapeutic strategies, particularly interdisciplinary family systems approaches like the well-documented Brain Injury Family Intervention (BIFI). Little is known about the experience of providers who offer such interventions.

OBJECTIVE

This mixed methods study aims to demonstrate that a structured three-day training on the BIFI protocol improves providers' knowledge and confidence in working with survivors and families, and that this outcome is sustainable.

METHODS

Participants were 34 providers who participated in an intensive training and completed a web-based survey at four points of time. Quantitative data were analyzed via Wilcoxon signed-rank tests and binomial test of proportions. Qualitative data were analyzed according to rigorous coding procedures.

RESULTS

Providers' knowledge of brain injury and their ability to conceptualize treatment models for survivors and their families increased significantly and mostly remain consistent over time. Qualitative data point to additional gains, such as understanding of family systems.

CONCLUSIONS

Past studies quantify the BIFI as an evidence-based intervention. This study supports the effectiveness of training and serves as first to demonstrate the benefit for providers short- and long-term.

The effectiveness of artificial intelligent 3-D virtual reality vocational problem-solving training in enhancing employment opportunities for people with traumatic brain injury

BACKGROUND

People with traumatic brain injury (TBI) often experience cognitive deficits in attention, memory, executive functioning and problem-solving. The purpose of the present research study was to examine the effectiveness of an artificial intelligent virtual reality (VR)-based vocational problem-solving skill training programme designed to enhance employment opportunities for people with TBI.

METHOD

This was a prospective randomized controlled trial (RCT) comparing the effectiveness of the above programme with that of the conventional psycho-educational approach. Forty participants with mild (n = 20) or moderate (n = 20) brain injury were randomly assigned to each training programme. Comparisons of problem-solving skills were performed with the Wisconsin Card Sorting Test, the Tower of London Test and the Vocational Cognitive Rating Scale.

RESULTS

Improvement in selective memory processes and perception of memory function were found. Across-group comparison showed that the VR group performed more favourably than the therapist-led one in terms of objective and subjective outcome measures and better vocational outcomes.

CONCLUSIONS

These results support the potential use of a VR-based approach in memory training in people with MCI. Further VR applications, limitations and future research are described.

Effect of psychological interventions on depressive symptoms in long-term rehabilitation after an acquired brain injury: a systematic review and meta-analysis

OBJECTIVE

To summarize empirical studies on the effectiveness of psychological interventions in long-term rehabilitation after an acquired brain injury (ABI) in reducing depressive symptoms.

DATA SOURCES

A systematic literature search was conducted on MEDLINE, PsycINFO, Embase, and CINAHL to identify articles published between January 1990 and October 2011. Search terms included the 3 concepts (1) "brain injur*" or "stroke," (2) "psychotherap*" or "therapy" or "intervention" or "rehabilitation," and (3) "depress*."

STUDY SELECTION

Studies evaluating psychological interventions in patients after ABI were included. Time since injury was on average more than 1 year. Trials reported data on validated depression questionnaires before and after the psychological intervention.

DATA EXTRACTION

Two independent reviewers extracted information from the sample, the intervention, and the outcome of the included studies and calculated effect sizes (ESs) from depression questionnaires. Thirteen studies were included in a pre-post analysis. Seven studies were eligible for a meta-analysis of ESs in active interventions and control conditions.

DATA SYNTHESIS

Pre-post ESs were significant in 4 of 13 studies. The overall ES of .69 (95% confidence interval [CI], .29-1.09) suggests a medium effectiveness of psychological interventions on depressive symptoms compared with control conditions. Moderator analysis of the number of sessions and adequate randomization procedure did not show significant ES differences between strata. Studies with adequate randomization did not, however, suggest the effectiveness of psychological interventions on depressive symptoms after ABI.

CONCLUSIONS

Psychological interventions are a promising treatment option for depressive symptoms in long-term rehabilitation after ABI. Since only a few adequately randomized controlled trials (RCTs) exist, more RCTs are required to confirm this initial finding.

A prospective study to evaluate a residential community reintegration program for patients with chronic acquired brain injury

OBJECTIVE

To examine the effects of a residential community reintegration program on independent living, societal participation, emotional well-being, and quality of life in patients with chronic acquired brain injury and psychosocial problems hampering societal participation.

DESIGN

A prospective cohort study with a 3-month waiting list control period and 1-year follow up.

SETTING

A tertiary rehabilitation center for acquired brain injury.

PARTICIPANTS

Patients (N=70) with acquired brain injury (46 men; mean age, 25.1y; mean time post-onset, 5.2y; at follow up n=67).

INTERVENTION

A structured residential treatment program was offered directed at improving independence in domestic life, work, leisure time, and social interactions.

MAIN OUTCOME MEASURES

Community Integration Questionnaire (CIQ), Employability Rating Scale, living situation, school, work situation, work hours, Center for Epidemiological Studies Depression Scale, EuroQOL quality of life scale (2 scales), World Health Organization Quality of Life Scale Abbreviated (WHOQOL-BREF; 5 scales), and the Global Assessment of Functioning (GAF) scale.

RESULTS

There was an overall significant time effect for all outcome measures (multiple analysis of variance T(2)=26.16; F(36,557) 134.9; P=.000). There was no spontaneous recovery during the waiting-list period. The effect sizes for the CIQ, Employability Rating Scale, work hours, and GAF were large (partial η(2)=0.25, 0.35, 0.22, and 0.72, respectively). The effect sizes were moderate for 7 of the 8 emotional well-being and quality of life (sub)scales (partial η(2)=0.11-0.20). The WHOQOL-BREF environment subscale showed a small effect size (partial η(2)=0.05). Living independently rose from 25.4% before treatment to 72.4% after treatment and was still 65.7% at follow up.

CONCLUSIONS

This study shows that a residential community reintegration program leads to significant and relevant improvements of independent living, societal participation, emotional well-being, and quality of life in patients with chronic acquired brain injury and psychosocial problems hampering societal participation.

Prospective study of a community reintegration programme for patients with acquired chronic brain injury: effects on caregivers' emotional burden and family functioning

OBJECTIVE

To examine the effects of a residential community reintegration programme for patients with psychosocial problems due to acquired chronic brain injury on caregivers' emotional burden and family functioning.

DESIGN

A prospective cohort study with waiting list control and 1-year follow-up.

SUBJECTS

Forty-one caregivers of which 28 female. Mean age was 48 ± 8.3 years and 33 caregivers were parents.

INTERVENTION

A structured residential treatment programme was offered to the patients directed at domestic life, work, leisure time and social interactions.

MEASURES

The Involvement Evaluation Questionnaire for Brain Injury (IEQ-BI) for emotional burden, the General Health Questionnaire (GHQ) for psychological health and the Family Assessment Device (FAD) for family functioning were used.

RESULTS

There was an overall significant effect of Time for all outcome measures (MANOVA T(2 )= 9.1, F(15,317) = 64.1, p = 0.000). The effect sizes were moderate for three IEQ-BI sub-scales (partial η(2 )= 0.12-0.17) and small for two sub-scales (partial η(2 )= 0.05-0.09). The effect size for GHQ was moderate (partial η(2 )= 0.11). As for FAD no significant time effects were present (partial η(2 )= 0.00-0.04).

CONCLUSIONS

Emotional burden and psychological health of the caregivers improved significantly when patients with acquired brain injury and psychosocial problems followed a residential community reintegration programme. Family dynamics remained stable.

Is it time to act? The potential of acceptance and commitment therapy for psychological problems following acquired brain injury

Behaviour therapies have a well-established, useful tradition in psychological treatments and have undergone several major revisions. Acceptance and Commitment Therapy (ACT) and mindfulness-based approaches are considered a third wave of behavioural therapies. Emerging evidence for ACT has demonstrated that this paradigm has promising effectiveness in improving functionality and well-being in a variety of populations that have psychological disturbances and/or medical problems. In this review we first evaluate traditional cognitive behavioural therapy (CBT) interventions used to manage psychological problems in distressed individuals who have sustained an acquired brain injury (ABI). We provide an overview of the ACT paradigm and the existent evidence base for this intervention. A rationale is outlined for why ACT-based interventions may have potential utility in assisting distressed individuals who have sustained a mild to moderate ABI to move forward with their lives. We also review emerging evidence that lends preliminary support to the implementation of acceptance and mindfulness-based interventions in the rehabilitation of ABI patient groups. On the basis of existent literature, we recommend that it is an opportune time for forthcoming research to rigorously test the efficacy of ACT-based interventions in facilitating ABI patient groups to re-engage in living a valued and meaningful life, in spite of their neurocognitive and physical limitations. The promising utility of testing the efficacy of the ACT paradigm in the context of multimodal rehabilitation programmes for ABI populations is also addressed.

Psychosocial considerations in occupational therapy treatment for adults with acquired brain injury: a survey

ABSTRACT The psychosocial factors of coping, locus of control, and self-efficacy have been shown to be associated positively with real-world outcomes following acquired brain injury (ABI), although to our knowledge there are no studies investigating whether occupational therapists address these factors in practice. This study used on-line survey methodology to investigate whether Canadian occupational therapists working in ABI rehabilitation were addressing these factors in their practice. Of 151 respondents, the majority reported being able to explain the factors to clients and that they and/or their team members were incorporating them into clinical practice. Participants also provided examples that were analyzed for common themes. The majority of examples of how these factors were incorporated into practice were implicit in nature. Further education regarding these factors may be warranted as only 25% of the respondents reported learning about these factors in their occupational therapy education.

Hope, dispositional optimism and severity of depression following traumatic brain injury

PRIMARY OBJECTIVE

To investigate the extent in which two coping variables-hope and dispositional optimism-are related to depression severity amongst individuals who have sustained traumatic brain injury (TBI).

METHODS AND PROCEDURES

Sixty-five participants were administered the Beck Depression Inventory (BDI), the Adult Hope Scale (AHS), the Life Orientation Test-Revised (LOT-R) and a demographic and injury-related data questionnaire. In addition, relevant injury-related data was collected from the medical records.

MAIN OUTCOMES AND RESULTS

High levels of depression were experienced in the study sample, while hope and dispositional optimism were significantly lower in comparison to the general population. The correlation patterns indicate that both hope and dispositional optimism negatively correlated with participants' depression levels and that they showed significant positive correlations with each other. In the case of mild depression, the hope-Pathways sub-scale of the AHS was the only variable negatively correlated to it, while in moderate-to-severe depression all coping variables were negatively correlated to it. Regression analysis revealed that the AHS and LOT-R, but not the demographic and injury-related variables, predicted depression severity.

CONCLUSIONS

Clinical implications in referring persons with TBI with mild vs. severe depression to rehabilitation programmes are discussed.

Cognitive deficits in heart failure: Re-cognition of vulnerability as a strange new world

BACKGROUND

Patients with chronic heart failure (HF) have impairment in memory, psychomotor speed, and executive function.

OBJECTIVE

The aim of this study was to describe how individuals with HF and cognitive deficits manage self-care in their daily lives.

METHODS

Using an interpretive phenomenology method, HF patients completed unstructured face-to-face interviews about their ability to manage complex health regimens and maintain their health-related quality of life. Analysis of data was aided by use of Atlas.ti computer software.

RESULTS

The sample consisted of 12 patients (10 men; aged 43-81 years) who had previously undergone neuropsychological testing and were found to have deficits in 3 or more cognitive domains. Patients confirmed that they followed the advice of healthcare providers by adherence to medication regimens, dietary sodium restrictions, and HF self-care. One overarching theme was identified: "Re-cognition of Vulnerability: A Strange New World." This theme was further differentiated into 3 components: (1) not recognizing cognitive deficits; (2) recognizing cognitive deficits, described as (a) never could remember anything, (b) just old age, (c) HF-related change, and (d) making normal accommodations; and (3) recognizing vulnerability, explained by perception of (a) cognitive, (b) physical, and (c) social vulnerabilities, as well as perception of (d) the nearness of death.

DISCUSSION

Although the study was designed to focus on the cognitive changes in HF patients, it was difficult to separate cognitive, physical, and social challenges. These changes are most useful when taken as a constellation. Healthcare professionals can use the knowledge to identify problems and interventions for HF patients.

The efficacy of cognitive behavior therapy in the treatment of emotional distress after acquired brain injury

OBJECTIVE

To evaluate the efficacy of cognitive behavior therapy (CBT), adapted to meet the unique needs of individuals with acquired brain injury (ABI), and modified for both group and telephone delivery.

DESIGN

Matched-controlled trial, with multiple measurements across participants, including pretreatment baseline assessment plus posttreatment and 1-month follow-up.

SETTING

Outpatient community brain injury center.

PARTICIPANTS

Participants (N=20) with chronic ABI. Ten were assigned to the CBT treatment group and 10 to education control. All were experiencing significant emotional distress at the onset of the study.

INTERVENTION

Eleven sessions of CBT (or education control), including 1 introductory individual session plus 10 further sessions administered in either group format or by telephone. The CBT was designed to decrease psychologic distress and improve coping. Specific adaptations were made to the CBT in order to better accommodate individuals with cognitive difficulties.

MAIN OUTCOME MEASURES

Primary outcome measures included the Symptom Checklist-90-Revised (SCL-90-R) and the Depression Anxiety Stress Scales (DASS-21). Secondary outcome measures included the Community Integration Questionnaire (CIQ) and the Ways of Coping Scale, Revised.

RESULTS

Significant CBT treatment effects (in both group and telephone formats) were observed on the SCL-90-R and the DASS-21, whereas no significant effects were observed in the education control group. No significant effects of treatment were observed on the CIQ or Ways of Coping Scale, Revised.

CONCLUSIONS

Results suggest that adapted CBT-administered by telephone or in a face-to-face group setting-can significantly improve emotional well-being in chronic ABI.

Cognitive function after chemotherapy in adults with solid tumours

BACKGROUND

Evidence is emerging that some cancer survivors suffer cognitive impairment after chemotherapy; the cause is unknown.

METHODS

Here we review studies evaluating cognitive impairment in adult cancer survivors and discuss methodological challenges associated with this research. We evaluate evidence for cognitive impairment in cancer patients, the incidence of self-reported impairment, and identify potential mechanisms and confounders.

RESULTS

Most studies of cognitive function are cross-sectional and report impairment in 15-45% of subjects. Longitudinal studies suggest that some impairment is present prior to receiving chemotherapy, and that this worsens in some patients. The aetiology is unknown. A larger number of subjects self-report changes in cognitive function after chemotherapy; this does not correlate with objective testing.

CONCLUSIONS

Cognitive impairment occurs in a subset of cancer survivors and is generally subtle. Most evidence suggests an association with chemotherapy although other factors associated with the diagnosis and treatment of cancer may contribute.

Psychological treatment for anxiety in people with traumatic brain injury

BACKGROUND

Psychological treatments are commonly used in the management of anxiety. Certain types of psychological treatments are well suited to needs of people with traumatic brain injury (TBI). We have systematically reviewed studies examining the effectiveness of these approaches for TBI.

OBJECTIVES

To assess the effects of psychological treatments for anxiety in people with TBI.

SEARCH STRATEGY

We searched the following databases up until March 2006: Cochrane Injuries Group's specialised register, Cochrane Depression, Anxiety and Neurosis Group's specialised register, Cochrane Central Register of Controlled Trials, MEDLINE, PsycINFO, EMBASE, CINAHL, AMED, ERIC, and PsycBITE. Additionally, key journals were handsearched and reference lists of included trials were examined to identify further studies meeting inclusion criteria.

SELECTION CRITERIA

Randomised controlled trials of psychological treatments for anxiety, with or without pharmacological treatment, for people with TBI were included in the review. Pharmacological treatments for anxiety in isolation (without psychological intervention) were excluded.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed methodological quality and extracted data from the included trials.

MAIN RESULTS

Three trials were identified in this review as satisfying inclusion criteria. Results of all three trials were evaluated, however, one of these trials had compromised methodological quality and, therefore the focus was placed on the other two trials. Data were not pooled due to the heterogeneity between trials. The first trial (n = 24) showed a benefit of cognitive behavioural therapy (CBT) in people with mild TBI and acute stress disorder. Fewer people receiving CBT had diagnosis of post-traumatic stress disorder (PTSD) at post-treatment compared to the control supportive counselling group, with maintenance of treatment gains found at six-month follow up. The second trial (n = 20) showed that post-treatment anxiety symptomatology of people with mild to moderate TBI was lower in the combined CBT and neurorehabilitation group compared to the no intervention control group.

AUTHORS' CONCLUSIONS

This review provides some evidence for the effectiveness of CBT for treatment of acute stress disorder following mild TBI and CBT combined with neurorehabilitation for targeting general anxiety symptomatology in people with mild to moderate TBI. These findings need to be viewed in light of the small number, small sample size and heterogeneous characteristics of current trials published in this area. More trials focusing on comparable psychological interventions, severity of injury of participants and diagnosis of anxiety disorder(s) are needed.

Characterising error-awareness of attentional lapses and inhibitory control failures in patients with traumatic brain injury

Awareness deficits are a significant problem following traumatic brain injury (TBI). This study examined error processing as candidate marker of awareness and compared the performance of 18 TBI participants and 18 controls using an online error-monitoring task while participants performed simple go/no-go tasks. Error-monitoring performance was compared where the no-go target was part of (a) a predictive sequence, (b) predictive sequence plus a dual-task element and (c) a random sequence. Results showed that the TBI participants, in contrast to control participants, were significantly impaired at monitoring their errors during both predictive sequence tasks but were not impaired on the random sequence task. These findings suggest that following TBI, when an error is more impulsive it may be more easily monitored, whereas when an error is characterised by attentional drift, subsequent error-processing mechanisms may fail to engage. Higher levels of online error-awareness were also associated with lower levels of anxiety, fewer symptoms of frontal dysfunction and greater competence in everyday functioning.

Psychotherapy Following Traumatic Brain Injury

Psychotherapy is now an approach used within several models of neurorehabilitation. However, a core theoretical model to guide psychotherapeutic practice is lacking. This article attempts to illustrate how the Generic Model of Psychotherapy of Orlinsky and Howard, which emphasizes the common factors shared by many psychotherapies, can be applied in neurorehabilitation settings. A case report is presented to illustrate how this model can potentially inform psychotherapeutic practice. The use of a theoretical model to underpin psychotherapeutic interventions in neurorehabilitation settings has the potential to facilitate our understanding of the psychotherapeutic process following traumatic brain injury in this evolving area of professional practice.

Treatment of depression following traumatic brain injury

Depression is a common consequence of traumatic brain injury (TBI), and is a source of substantial distress and disability for persons with TBI and their families. This article offers a practical approach to the evaluation and treatment of this condition. Diagnostic and etiologic considerations relevant to this issue are reviewed first. Next, somatic therapies for posttraumatic depression, including antidepressant medications and electroconvulsive therapy, are discussed. Use of these therapies is also considered in the context of the common medical and neurological comorbidities among persons with TBI. Finally, psychosocial interventions relevant to the care of persons with posttraumatic depression are presented.

Psychiatric disturbances after traumatic brain injury: neurobehavioral and personality changes

Traumatic brain injuries (TBI) are frequently accompanied by psychiatric disturbances, which can include striking to relatively minor alterations in personality, behavior, and emotional regulation. The persistence of these neurobehavioral syndromes often leads to deleterious effects on recovery and rehabilitation outcomes. A recent surge of studies has emerged in the past several years to quantify the extent of psychiatric disorders in TBI and to describe differential clinical presentations. Various pre- and post-injury factors also have been hypothesized to contribute to the development and maintenance of psychiatric symptoms in survivors of brain injuries. The identification of high-risk individuals with distinct neuropathophysiological and psychosocial features permits the development of multidisciplinary and tailored approaches to the assessment, prevention, and management of the negative effects of personality and behavioral changes in TBI. This article summarizes the most recent research in these areas and highlights the gaps that need to be filled in subsequent future.

Rehabilitation interventions after mild head injury

PURPOSE OF REVIEW

This review examines current management and rehabilitation strategies for mild traumatic brain injury, with emphasis on the need to address multiple potential causative factors in order to enhance outcomes and to conduct more controlled efficacy studies.

RECENT FINDINGS

Whilst most individuals who sustain mild traumatic brain injury make a good recovery, a proportion experience significant ongoing disability. In some cases this is due to diffuse axonal injury and cognitive impairment, but in others symptoms are exacerbated by factors such as pain, stress, personality issues or litigation, or in children, previous head injury, behavioural or learning difficulties. Provision of information early after injury results in reduced symptom reporting in adults and children. There is also a need, however, to address these other factors in treatment. Psychological therapy using a cognitive behavioural approach may be helpful, but controlled evaluations of such interventions have been lacking. Recent uncontrolled studies have examined the impact of computer-mediated interventions to remediate visual and verbal processing and oculomotor problems and the impact of quantitative electroencephalography. More rigorous efficacy studies of these approaches are needed. Guidelines for management of sports-related concussion and timing of return to play also require a more solid scientific basis.

SUMMARY

The evidence base for management of mild traumatic brain injury is still very limited. There is a need to conduct more carefully controlled prospective studies and examine the influence of factors not directly related to the brain injury as a basis for formulating more uniform management guidelines.
