Virtual reality as a method of cognitive training of processing speed, working memory, and sustained attention in persons with acquired brain injury: a protocol for a randomized controlled trial

BACKGROUND

Acquired brain injury (ABI) often leads to persisting somatic, cognitive, and social impairments. Cognitive impairments of processing speed, sustained attention, and working memory are frequently reported and may negatively affect activities of daily living and quality of life. Rehabilitation efforts aiming to retrain these cognitive functions have often consisted of computerized training programs. However, few studies have demonstrated effects that transfer beyond the trained tasks. There is a growing optimism regarding the potential usefulness of virtual reality (VR) in cognitive rehabilitation. The research literature is sparse, and existing studies are characterized by considerable methodological weaknesses. There is also a lack of knowledge about the acceptance and tolerability of VR as an intervention method for people with ABI. The present study aims to investigate whether playing a commercially available VR game is effective in training cognitive functions after ABI and to explore if the possible effects transfer into everyday functioning.

METHODS

One hundred participants (18-65 years), with a verified ABI, impairments of processing speed/attention, and/or working memory, and a minimum of 12 months post injury will be recruited. Participants with severe aphasia, apraxia, visual neglect, epilepsy, and severe mental illness will be excluded. Participants will be randomized into two parallel groups: (1) an intervention group playing a commercial VR game taxing processing speed, working memory, and sustained attention; (2) an active control group receiving psychoeducation regarding compensatory strategies, and general cognitive training tasks such as crossword puzzles or sudoku. The intervention period is 5 weeks. The VR group will be asked to train at home for 30 min 5 days per week. Each participant will be assessed at baseline with neuropsychological tests and questionnaires, after the end of the intervention (5 weeks), and 16 weeks after baseline. After the end of the intervention period, focus group interviews will be conducted with 10 of the participants in the intervention group, in order to investigate acceptance and tolerability of VR as a training method.

DISCUSSION

This study will contribute to improve understanding of how VR is tolerated and experienced by the ABI population. If proven effective, the study can contribute to new rehabilitation methods that persons with ABI can utilize in a home setting, after the post-acute rehabilitation has ended.

Cognitive and everyday functioning after bacterial brain abscess: a prospective study of functional recovery from 8 weeks to 1 year post-treatment

OBJECTIVE

A bacterial brain abscess may damage surrounding brain tissue by mass effect, inflammatory processes, and bacterial toxins. The aim of this study was to examine cognitive and functional outcomes at 8 weeks and 1 year following acute treatment.

METHODS

Prospective study of 20 patients with bacterial brain abscess (aged 17-73 years; 45% females) with neuropsychological assessment at 8 weeks and 1 year post-treatment. Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A) and Patient Competence Rating Scale (PCRS) were used to assess everyday functioning and administered to patients and informants.

RESULTS

Cognitive impairment was found in 30% of patients at 8 weeks and 22% at 1 year. Significant improvements were seen on tests of perceptual reasoning, attention, verbal fluency, and motor abilities (p < 0.05). At 1 year, 45% had returned to full-time employment. Nevertheless, patients and their informants obtained scores within the normal range on measures of everyday functioning (PCRS and BRIEF-A) at 8 weeks and 1 year. No significant improvements on these measures emerged over time.

CONCLUSION

Residual long-term cognitive impairment and diminished work ability affected 22% and 45% of patients one year after BA. Persistent cognitive impairment emphasizes the importance of prompt acute treatment and cognitive rehabilitation.

Awareness through relationships in individuals undergoing rehabilitation following acquired brain injury

AIM

This cross-sectional study investigated the association between self-awareness and quality of therapeutic relationships following acquired brain injury (ABI) while controlling for the potential impact of cognitive problems. It also aimed to investigate attachment as a potential moderator.

METHOD

83 adults with ABI were recruited alongside a key member of their community neurorehabilitation team. The Scale to Assess Therapeutic Relationships (STAR) was used to measure therapeutic relationship quality and attachment was measured using the Experiences in Close Relationships - Relationship Structure (ECR-RS) questionnaire. Awareness was measured using the Patient Competency Rating Scale (PCRS) and the Mayo-Portland Adaptability Inventory (MPAI-4) provided a measure of cognitive problems. The MPAI-4 also provided an additional measure of awareness.

RESULTS

A significant association between self-awareness and therapeutic relationships was found in some regression models such that higher-quality relationships were associated with better awareness, after controlling for the impact of cognitive problems. Neither childhood parental attachment nor participants' attachment towards their rehabilitation staff were moderators.

CONCLUSION

The observed associations between awareness in clients and therapeutic relationships with rehabilitation staff may have importance for rehabilitation in this context. Results highlight the value of continuing to prioritize the therapeutic relational environment in ABI rehabilitation and research.

Measuring domain-specific deficits in self-awareness in children and adolescents with acquired brain injury: Component analysis of the Paediatric Awareness Questionnaire

Self-awareness has been found to vary across different functional domains for adults with acquired brain injury (ABI); however, domain-specific self-awareness is yet to be investigated following paediatric ABI. This study aimed to validate the Paediatric Awareness Questionnaire (PAQ) as a multi-domain measure of self-awareness and to investigate domain-specific self-awareness in children with ABI. One hundred and ninety-seven children and adolescents (8-16 years, M = 12.44, SD = 2.62) with mixed causes of ABI (70% with traumatic brain injury) and their parents (n = 197) were recruited through consecutive rehabilitation appointments and completed the PAQ. The 37 items of the parent version of the PAQ were subjected to a principal component analysis with varimax rotation. A five-component solution (29 items) explained 64% of the variance in the PAQ items. Components revealed five domains of self-awareness: socio-emotional functioning, activities of daily living (ADLs), cognition, physical functioning, and communication. Internal consistency of the components ranged from acceptable to excellent (α = .70-.95). The analysis identified that children had poorer self-awareness of cognitive functioning than socio-emotional functioning, ADLs, and communication skills. Overall, the findings identify five components (i.e., functional domains) of self-awareness and provide some support that self-awareness varies across domains following paediatric ABI.

Patient Competency Rating Scale-Brazilian Revised Version (PCRS-R-BR): Normative and Psychometric Data in 154 Healthy Individuals

Background Patient Competency Rating Scale (PCRS-R-BR) is a clinical tool to evaluate the degree of competence in cognitive skills perceived by patients with brain injuries. However, no studies have investigated the influence of sociodemographic variables on self-report and self-awareness of healthy individuals.Aim This study aimed to (1) present normative data from the PCRS-R-BR in a healthy adult Brazilian sample; and (2) investigate psychometric properties of the scaleMethod One hundred and fifty-four adults that were divided in three age groups and two education groups and their informants completed the PCRS-R-BR.Results Score on the PCRS-R-BR Patient's Form differed as a function of age with younger adults reporting less competency than older individuals. An education effect was found on Attention/Working memory Factor on the Informant's PCRS-R-BR with informants of higher education adults reporting better competency than lower education individuals. A gender effect was observed on the Informant's Form. The Informant's Form scores of informants of women were higher than the scores provided by the informants of men. PCRS-R-BR showed adequate consistency coefficients and six factors.Conclusion PCRS-R-BR scores showed acceptable validity evidence and provides information regarding how age and gender effects may influence ratings in a Brazilian sample.

Impaired Self-Awareness and Denial During the Postacute Phases After Moderate to Severe Traumatic Brain Injury

While a number of empirical studies have appeared on impaired self-awareness (ISA) after traumatic brain injury (TBI) over the last 20 years, the relative role of denial (as a psychological method of coping) has typically not been addressed in these studies. We propose that this failure has limited our understanding of how ISA and denial differentially affect efforts to rehabilitate persons with TBI. In this selective review paper, we summarize early findings in the field and integrate those findings with more recent observations (i.e., 1999–2019). We believe that this synthesis of information and expert clinical opinion will inform future research on ISA and denial as well as approaches to rehabilitation for persons with TBI.

Trajectories of self-reported competency up to 10 years following moderate-to-severe traumatic brain injury

Objectives: To describe trajectories of self-reported functional competency up to 10 years following traumatic brain injury (TBI) and identify their predictors from baseline socio-demographic and injury severity characteristics.Design and methods: Data from 94 participants from a longitudinal cohort of patients with moderate-to-severe TBI were analyzed. Socio-demographic and injury severity data were recorded at baseline. Participants completed the Patient Competency Rating Scale (PCRS) at 1, 2, 5, and 10 years. Hierarchical linear modeling was used to examine PCRS trajectories over time and assess baseline predictors.Results: There was no significant change in average PCRS scores across the follow-up time points in the full sample. Emotional and cognitive competencies had the lowest mean scores. Gender, employment, and the interaction term between gender and time were significant predictors of PCRS trajectories. Females and those who were unemployed at the time of injury showed lower trajectories of self-reported competency.Conclusion: Self-reported competency remained stable from one-year post-injury for men only. Lower mean scores in the domains of emotional and cognitive competencies suggest a need for continued rehabilitation focus in the chronic phase after TBI. Special attention to women and individuals who are unemployed at the time of injury may be warranted.
