Cognitive-communication difficulties due to traumatic brain injury sustained in adults 55 years and older: A survey of speech-language pathology professional practice in Australia.

PURPOSE: Limited research informs management of cognitive-communication difficulties following traumatic brain injury (TBI) in older adulthood. The purpose of this study was to understand the characteristics and practice of speech-language pathologists (SLPs) working with people who sustained TBI at ≥55 years and more specifically their management of cognitive-communication difficulties with this population. This included assessment and treatment practices, resource needs, barriers to practice, and impact to service delivery from COVID-19 restrictions. METHOD: A cross-sectional survey-based design with non-probability sampling of SLPs working in Australia with adults with TBI was utilised. Descriptive statistics and content analysis were used for analysis of survey data. RESULT: Fifty responses were eligible for inclusion. Participants predominantly worked in inpatient rehabilitation (48%), acute (40%), and community settings (36%). Service delivery to adults who sustained TBI at ≥55 years commonly included cognitive-communication management. Assessment and treatment trends are described. Most SLPs (74%) perceived barriers to cognitive-communication management, often relating to time and funding, that existed prior to the COVID-19 pandemic. Pandemic restrictions presented additional challenges. CONCLUSION: Research relating to cognitive-communication difficulties following TBI in older adulthood is required to support evidence-based practice and inform services for older adults who sustain TBI.

Insights into social communication following traumatic brain injury sustained in older adulthood.

BACKGROUND: There is a lack of evidence relating to cognitive-communication difficulties following traumatic brain injury (TBI) sustained in older adulthood. A prominent area in which post-TBI cognitive-communication difficulties manifest is at the level of social communication. An investigation of social communication focusing on comparison of those injured in older and younger adulthood is a practical starting point for age-related cognitive-communication outcome comparison. AIMS: The overall objective of this study was to explore the social communication of individuals who sustained severe TBI in an early period of older adulthood (50-70 years) compared to younger adulthood (18-40 years), as informed by self and close other reports. METHODS & PROCEDURES: This exploratory controlled group comparison study involved analysis of self-reported and close other reported La Trobe Communication Questionnaire data for 22 adults with severe TBI (11 older at injury; 11 younger at injury) and 22 control participants (11 older; 11 younger). TBI participants were matched for injury variables and participant groups were matched for sex, age and education. OUTCOMES & RESULTS: The close others of the older and younger adults with TBI reported them to have significantly more frequent difficulty with social communication than the close others of age-matched control groups. Older adults with TBI reported significantly more frequent difficulty with social communication than uninjured older adults. In contrast, younger adults with TBI and uninjured younger adults reported a similar frequency of difficulty with social communication. No age-based difference in the frequency of social communication difficulty was evident when comparing the self or close other reports of older and younger adults with TBI. Awareness of social communication difficulty, as indexed by comparing self and close other perceptions, showed a different pattern across the TBI groups. The older TBI group rated themselves as having significantly less frequent social communication difficulty than was perceived by their close others. In contrast, no statistically significant difference was evident between the self and close other social communication ratings of the younger TBI group. CONCLUSIONS AND IMPLICATIONS: Where possible clinicians need to work with close communication partners to understand the nature and degree of social communication difficulty following severe TBI. This may be especially important when working with people who sustain TBI in older adulthood if future research shows that this population have greater difficulty with self-awareness of social communication difficulty. WHAT THIS PAPER ADDS: What is already known on the subject Cognitive-communication difficulties are a common consequence of traumatic brain injury (TBI) that can have long-term impact on everyday functioning. These challenges have primarily been investigated in individuals who sustained TBI in younger adulthood. What this paper adds to existing knowledge Individuals who sustain severe TBI in early older adulthood have a higher frequency of reported social communication difficulty to non-injured adults of a similar age, albeit they may underreport such difficulties potentially in the context of reduced self-awareness. What are the potential or actual clinical implications of this work? Social communication difficulty is an issue for people who sustain severe TBI in early older adulthood. However, a poorer overall social communication outcome in comparison to those injured in younger adulthood should not be assumed. Clinical service delivery for these challenges is most optimally delivered in a collaborative manner with the individual and their close others. Future research is required to investigate the identified trends from this study.

Age-Based Trends in Cognitive-Communication Management for Adults in Subacute Rehabilitation Following New Onset Traumatic Brain Injury.

PURPOSE: Although traumatic brain injury (TBI) has a disproportionate impact on older adults, there has been limited inclusion of these individuals in post-TBI cognitive-communication research. This study was undertaken to compare demographic and injury characteristics, speech-language pathology input, and broad outcomes for younger and older adults admitted to inpatient rehabilitation following TBI. METHOD: A retrospective audit of first occasion adult TBI admissions in 2019 to inpatient rehabilitation in an Australian metropolitan subacute hospital was conducted via medical record data. Admissions were located using International Statistical Classification of Diseases, Tenth Revision, Australian Modification (ICD-10-AM) coding that aligned with TBI. Comparisons were made for younger (18-54 years) and older (≥ 55 years) adults. RESULTS: A total of 114 admissions (51.75% older adults) were included. Patient age ranged between 18 and 90 years. Falls caused TBI in the majority of older adults, whereas transport-related accidents were the most common cause for younger adults. Age-based trends for intracranial injury were observed. Cognitive-communication difficulties were the most common speech-language pathology diagnosis with no significant difference in prevalence between younger and older adults. Age group was not significantly associated with length of stay or discharge home. CONCLUSIONS: The implications of injury-related trends for older adults on post-TBI cognitive-communication are poorly understood. This lack of information is problematic given the frequency of cognitive-communication difficulties in this population. Research into cognitive-communication following new onset TBI in older adults is crucial to support rehabilitation service provision and improve outcomes for older adults.

Cognitive-communication difficulties following traumatic brain injury sustained in older adulthood: a scoping review.

BACKGROUND: Older adults are a peak incidence group for traumatic brain injury (TBI). However, empirical evidence on TBI in older adults is often limited to extrapolated findings from studies involving younger adults. While cognitive-communication deficits are an established consequence of TBI with substantial impact on social outcome for younger adults, little is known about the nature of cognitive-communication changes experienced by older adults following a new-onset TBI. In order to inform evidence-based service delivery and support older adults who sustain TBI, it is important to understand how these difficulties manifest in older adults. AIMS: To review the empirical literature to determine the nature and breadth of research that has addressed the influence of older age on cognitive-communication outcomes following TBI sustained in older adulthood. METHODS & PROCEDURES: A scoping review framework was used. Five electronic databases (Medline, PsycINFO, Embase, CINAHL and Scopus) were searched to locate peer-reviewed studies addressing cognitive-communication following TBI sustained at ≥ 55 years. Given the absence of dedicated investigations within the search yield, studies were included where at least 30% of participants were aged ≥ 55 years at injury, and age was a stated focus of the investigation. OUTCOMES & RESULTS: A total of 2468 unique records were identified and reduced to 225 after title and abstract screening. Full-text review revealed only three studies that met the criteria. Collectively these studies included adults aged 55-93 years at injury. Two studies focused on age as a predictor for acute cognitive-communication difficulty, and one on the impact of age on facial emotion recognition in the chronic stages of injury. None of the studies had a dedicated focus on cognitive-communication outcomes for older adults who sustained a TBI within the defined period of older adulthood. CONCLUSIONS & IMPLICATIONS: This scoping review produced limited results and insufficient evidence to inform rehabilitation for older adults. Indeed, very little is known about cognitive-communication outcomes for older adults who sustain a TBI. This review highlights the need, in the context of an ageing population, for research within this area to be prioritized. What this paper adds What is already known on the subject Empirical evidence to support the management of post-TBI cognitive-communication difficulties in adults predominantly stems from studies with young adults. However, the broader TBI literature suggests that outcome for older adults requires specific consideration due to its distinct nature and occurrence during a stage of life when there is the potential for subtle change to the processes of cognition and communication as part of typical ageing. What this paper adds to existing knowledge This scoping review identifies that research related to cognitive-communication outcomes for older adults who have sustained a TBI is very much in its infancy. Overarching statements about post-TBI cognitive-communication outcomes for older adults cannot be drawn, nor can it be determined if outcomes for older adults differ from younger adults. What are the potential or actual clinical implications of this work? The lack of research in this area means that tangible guidance cannot be provided to clinicians working with older adults following TBI to support evidence-based practice for cognitive-communication. This scoping review strongly supports the need for further research in this area.

Understanding the role of communication in maintaining and forming friendships following traumatic brain injury.

PRIMARY OBJECTIVE: To describe and analyse how two adults with traumatic brain injury (TBI) construct meaning about their communication and its impact upon friendships. This information was sought with a view to understanding whether these adults perceived a link between their post-TBI communication and their experience of friendship; and, in addition, which aspects of their communication, if any, emerged as being important in this scenario. RESEARCH DESIGN: A qualitative approach based on Grounded Theory. METHODS AND PROCEDURES: Purposive sampling of two participants living in the community at a minimum of 2 years post-severe TBI was utilized. Data was collected via in-depth semi-structured interviews. Transcripts were analysed for categories and themes. OUTCOMES AND RESULTS: Three major themes were evident: (1) The experience of friendship following TBI, (2) Changes to conversational skill and (3) Opening up to others. Communication change was important in the experience of friendships in so much as difficulties with conversational skill impacted on participation levels and self-disclosure. Participants identified aspects of communication associated with difficulties when interacting with friends and peers. CONCLUSIONS: Participants' stories illustrate the need to address post-TBI communication difficulties within social contexts. Further research addressing communication difficulties that impact on friendships specific to gender, age and time post-injury is warranted.
