Social communication assessment during post-traumatic amnesia and the post-acute period after traumatic brain injury

Post-traumatic amnesia: a scoping review & content analysis of behavioral disturbances

OBJECTIVE

The aim of this scoping review was to identify behavioral disturbances exhibited by patients in post-traumatic amnesia (PTA). While behavioral disturbances are common in PTA, research into their presentation and standardized measures for their assessment are limited.

DESIGN

The study protocol was registered with PROSPERO (CRD42021268275). A scoping review of databases was performed according to pre-determined criteria on 29 July 2021 and updated on 13 July 2022. A conventional content analysis was used to examine and categorize behavioral disturbances.

RESULTS

Thirty papers met the inclusion criteria, of which 27 reported observations and/or scores obtained on behavioral scales, and 3 on clinician interviews and surveys. None focused exclusively on children. Agitation was the most frequently assessed behavior, and Agitated Behavior Scale was the most used instrument. Content analysis, however, bore eight broad behavioral categories: disinhibition, agitation, aggression, lability, lethargy/low mood, perceptual disturbances/psychotic symptoms, personality change and sleep disturbances.

CONCLUSION

Our study revealed that while standardized assessments of behavior of patients in PTA are often limited to agitation, clinical descriptions include a range of behavioral disturbances. Our study highlights a significant gap in the systematic assessment of a wide range of behavioral disturbances observed in PTA.

Meeting the confused patient with confidence: perceived benefits of communication partner training in subacute TBI

OBJECTIVE

This study aims to explore health professionals' perceived benefits of implementing Communication Partner Training (CPT) using Supported Conversation for Adults with Aphasia (SCA™) in a subacute rehabilitation setting with patients in post-traumatic confusional state (PTCS) after TBI.

METHOD

The study was conducted in a clinical setting using a pre-post questionnaire design to explore change. One hundred and four interdisciplinary clinicians attended CPT in the SCA™ method and subsequent implementation support. Participants completed a questionnaire with both quantitative and qualitative questions before and after the training and implementation period. Data were analyzed using descriptive and inferential statistics and qualitative content analysis.

RESULTS

Participants' perceived confidence and self-assessed ability to communicate with patients in PTCS significantly increased after CPT (p = 0.006). While participants still experienced communication challenges, they reported using CPT-related tools and strategies in their interactions. Participants found they could apply strategies to improve patients' comprehension of information and to confirm their understanding of patients' communication. However, using strategies to enhance patients' expressive abilities was perceived as more challenging.

CONCLUSIONS

Training health professionals in CPT increase their confidence in managing communication with patients in PTCS. Further research is needed to evaluate the efficacy of CPT within a more rigorous research design.

First-Line Health Care Providers' Reported Knowledge of and Referrals to Speech-Language Pathologists for Clients With Mild Traumatic Brain Injury

Purpose People with mild traumatic brain injury (mTBI) may experience deficits in cognition or communication that go unnoticed by first-line health care providers (FHPs). Speech-language pathologists (SLPs) assess and treat these domains yet are often underrepresented on mTBI multidisciplinary teams. This study's aim was to evaluate FHPs' reported knowledge of and referral practices to SLPs for individuals across the life span with mTBI. Method Physicians, physician assistants, nurse practitioners, nurses, and athletic trainers (n = 126) completed an online survey, including two Likert scale questions and one free response question relating to SLPs' role in mTBI. Results More than half of FHPs rate their knowledge of the SLP's role in mTBI management as low (somewhat knowledgeable, 29%; not very knowledgeable, 23%). Similarly, nearly two thirds of FHPs indicated rarely (19%) or never (44%), referring to SLPs for management of patients with mTBI. The majority of FHPs' open responses on the role of the SLP in mTBI management were incomplete, with many including domains that were not relevant to an SLP's role in the management of mTBI (e.g., dysphagia). Within the article, we provide results overall and according to individual profession. Conclusions Results suggest a majority of FHPs lack knowledge in the role of the SLP in the management of mTBI, which may underpin the low referral patterns reported by FHPs for SLP services. Future educational efforts for FHPs regarding the role of SLPs in mTBI care are necessary.

The Cognitive-Communication Checklist for Acquired Brain Injury: A Means of Identifying, Recording, and Tracking Communication Impairments

Purpose The communication service needs of individuals with acquired brain injuries (ABIs) are frequently overlooked, leading to delays, denials, or premature discharge from communication interventions. This is particularly true for those with subtle cognitive-communication deficits, which may not be apparent until sufficiently challenged at work, in school, or in the community. The purpose of this study was to evaluate a referral tool that could promote understanding of the broad range of communication impairments that occur following ABI and lead to improved identification and referral. Method This study evaluated the Cognitive-Communication Checklist for Acquired Brain Injury (CCCABI) through a survey. The CCCABI is a referral tool that summarizes 45 communication difficulties in 10 areas of cognitive-communication functioning. One hundred sixteen speech-language pathologists, 34 multidisciplinary referral sources, and 41 individuals with lived experience of brain injury were surveyed to evaluate the utility of this referral tool. Results The need for such a referral tool was endorsed by 96% of speech-language pathology respondents, 91% of multidisciplinary respondents, and 100% of respondents with lived experience of brain injury. Responses supported the CCCABI as a clear, comprehensive, and accessible tool for education and identification of the communication impairments that can occur after ABI. Conclusion The CCCABI is a means of increasing understanding of communication service needs following ABI in a manner that is accessible to individuals, families, program designers, funding sources, administrators, and multidisciplinary referral sources.

More than amnesia: prospective cohort study of an integrated novel assessment of the cognitive and behavioural features of PTA

Background and Objective:

Post-traumatic amnesia (PTA) is an early significant stage of recovery from traumatic brain injury (TBI). Current prospective PTA scales do not assess the full range of PTA symptomatology. This study conducted a novel integrated assessment of cognition and behaviour during PTA.

Method:

Twenty-four moderate-to-severe TBI participants in PTA and 23 TBI controls emerged from PTA were matched for age, gender, and years of education. All completed PTA measures (Galveston Orientation and Amnesia Test: GOAT, Westmead Post-traumatic Amnesia Scale: WPTAS), a cognitive battery; and behaviour ratings scored by 2 independent raters (informant and staff).

Results:

Significantly poorer performance was found during PTA for attention, processing speed, delayed verbal free recall and recognition, and visual learning. A large effect size was found for category fluency only. Behaviour ratings were significantly higher during PTA. Five behaviours were rated as high frequency (>50%) by both raters: Inattention, Impulsivity, Sleep Disturbance, Daytime Arousal, and Self-Monitoring. Prospective PTA measures produced significantly different duration estimates from 2 days (GOAT vs. WPTAS 1st day) to 9 days (WPTAS 1st day vs. 3-day). The WPTAS correlated most highly with processing speed and language tasks; whilst the GOAT correlated most highly with language and executive control of verbal memory.

Conclusion:

New prospective measures are needed that integrate core cognitive and behavioural features are brief, easy to administer, and capable of measuring emergence. The term PTA is a misnomer that requires revision to better accommodate the clinical syndrome.

Social communication assessment after TBI: a narrative review of innovations in pragmatic and discourse assessment methods

BACKGROUND

Social communication assessment after traumatic brain injury (TBI) remains a challenging area within speech-language pathology (SLP) clinical practice. Difficulties include the lack of TBI-specific standardized assessment instruments and limited knowledge and uptake of discourse assessment methods clinically. The aim of this paper was to review recent research literature reporting on innovative social communication and discourse assessment measures and methods, to guide evidence-based SLP practice and inform future research.

MAIN CONTRIBUTION

This review describes novel standardized and non-standardized assessment tools for SLP use reported in TBI research literature from the past 15 years. Measures include published assessment batteries and pragmatic rating scales designed for use with adults with TBI, and novel discourse tasks and protocols.

CONCLUSION

This paper delineates social communication assessment measures and discourse analyses described in research literature that may be practical for SLPs to use with adults with TBI. The clinical implications and utility of these measures are discussed. This should assist SLPs in decision-making on social communication assessment for adults with TBI. Further research is needed to investigate translation of research knowledge on discourse assessment methods to SLP practice.

Improvement of Attention-Deficit/Hyperactivity Disorder Symptoms in School-Aged Children, Adolescents, and Young Adults With Autism via a Digital Smartglasses-Based Socioemotional Coaching Aid: Short-Term, Uncontrolled Pilot Study

BACKGROUND

People with autism spectrum disorder (ASD) commonly experience symptoms related to attention-deficit/hyperactivity disorder (ADHD), including hyperactivity, inattention, and impulsivity. One-third of ASD cases may be complicated by the presence of ADHD. Individuals with dual diagnoses face greater barriers to accessing treatment for ADHD and respond less positively to primary pharmacologic interventions. Nonpharmacologic technology-aided tools for hyperactivity and inattention in people with ASD are being developed, although research into their efficacy and safety remains limited.

OBJECTIVE

The objective of this preliminary study was to describe the changes in ADHD-related symptoms in children, adolescents, and young adults with ASD immediately after use of the Empowered Brain system, a behavioral and social communication aid for ASD running on augmented reality smartglasses.

METHODS

We recruited 8 children, adolescents, and young adults with ASD (male to female ratio of 7:1, mean age 15 years, range 11.7-20.5 years) through a Web-based research signup form. The baseline score on the hyperactivity subscale of the Aberrant Behavioral Checklist (ABC-H), a measure of hyperactivity, inattention, and impulsivity, determined their classification into a high ADHD-related symptom group (n=4, ABC-H≥13) and a low ADHD-related symptom group (n=4, ABC-H<13). All participants received an intervention with Empowered Brain, where they used smartglasses-based social communication and behavioral modules while interacting with their caregiver. We then calculated caregiver-reported ABC-H scores at 24 and 48 hours after the session.

RESULTS

All 8 participants were able to complete the intervention session. Postintervention ABC-H scores were lower for most participants at 24 hours (n=6, 75%) and for all participants at 48 hours (n=8, 100%). At 24 hours after the session, average participant ABC-H scores decreased by 54.9% in the high ADHD symptom group and by 20% in the low ADHD symptom group. At 48 hours after the session, ABC-H scores compared with baseline decreased by 56.4% in the high ADHD symptom group and by 66.3% in the low ADHD symptom group.

CONCLUSIONS

This study provides initial evidence for the possible potential of the Empowered Brain system to reduce ADHD-related symptoms, such as hyperactivity, inattention, and impulsivity, in school-aged children, adolescents, and young adults with ASD. This digital smartglasses intervention can potentially be targeted at a broader array of mental health conditions that exhibit transdiagnostic attentional and social communication deficits, including schizophrenia and bipolar disorder. Further research is required to understand the clinical importance of these observed changes and to conduct longitudinal studies on this intervention with control groups and larger sample sizes.
