Blood biomarkers are an emerging diagnostic and prognostic tool that reflect a range of neuropathological processes following traumatic brain injury (TBI). Their effectiveness in identifying long-term neuropathological processes after TBI is unclear. Studying biomarkers in the chronic phase is vital because elevated levels in TBI might result from distinct neuropathological mechanisms during acute and chronic phases.

Memory dysfunction is a persistent cognitive symptom following traumatic brain injury (TBI), negatively impacting capacity for independent living and productivity. Traditional scoring of neuropsychological memory tests does not allow for differentiation of specific impairments of encoding, consolidation and/or retrieval, or the potential impact of strategy deficits. The current study examined performance of 142 moderate-to-severe TBI participants and 68 demographically matched healthy controls on the Rey Auditory Verbal Learning Test (RAVLT) using Item Specific Data Analysis (ISDA) and strategy use analyses.

Article Synopsis
  • * A rapid systematic review identified 39 initiatives across 29 neurological conditions, highlighting a lack of established methods for defining data dictionaries, with only some initiatives involving patient input.
  • * Key methods for consultation included roundtable discussions and iterative processes, emphasizing the need for more engagement with individuals with lived experience of TBI, which could help enhance data dictionary development for AUS-TBI.

The Australian Traumatic Brain Injury Initiative (AUS-TBI) aims to select a set of measures to comprehensively predict and assess outcomes following moderate-to-severe traumatic brain injury (TBI) across Australia. The aim of this article was to report on the implementation and findings of an evidence-based consensus approach to develop AUS-TBI recommendations for outcome measures following adult and pediatric moderate-to-severe TBI. Following consultation with a panel of expert clinicians, Aboriginal and Torres Strait Islander representatives and a Living Experience group, and preliminary literature searches with a broader focus, a decision was made to focus on measures of mortality, everyday functional outcomes, and quality of life.

Background Challenging behaviours are often a significant difficulty faced following acquired brain injury (ABI), for which PBS+PLUS (a Positive Behaviour Support framework) is an effective intervention. Clinicians report experiencing a range of barriers to supporting behaviour change for individuals with ABI and require tailored resources to support the implementation of PBS+PLUS. This study aimed to describe the process of co-designing a PBS+PLUS intervention guidebook and podcast series together with individuals with ABI, close-others, and clinicians, and qualitatively examine co-design experiences.

Background Persistent changes in sexuality often follow traumatic brain injury (TBI). However, health professionals remain reticent about discussing sexuality and have reported barriers including uncertainties around whose role it is and limited educational and institutional support. This study employed a co-design and implementation process, aiming to promote team-wide behavioural change, whereby health professionals at a TBI rehabilitation unit would attempt to address sexuality with patients routinely.

Background Although individuals with acquired brain injury (ABI) may be vulnerable to cyberscams, the lack of existing measures documenting cybersafety behaviours in people with ABI limits our understanding of ABI-specific risk factors, the frequency of this problem, and the ability to evaluate evidence-based interventions. The CyberABIlity Scale was developed to assess vulnerability in people with ABI via self-rated statements and practical scam-identification tasks. This study aimed to develop and refine The CyberABIlity Scale through feedback from clinicians and people with ABI.

Objective: Given the high variability in traumatic brain injury (TBI) outcomes and relative lack of examination of the influence of noninjury factors on outcome, this study aimed to examine factors associated with functional outcome at 1 and 2 years after moderate to severe TBI, including both preinjury and injury-related factors.

Design: Observational cohort study.

Setting: Inpatient hospital recruitment with outpatient follow-up at 1 and 2 years post injury.

Background And Objectives: Blood biomarkers glial fibrillary acidic protein (GFAP) and ubiquitin carboxy-terminal hydrolase L1 (UCH-L1) have recently been Food and Drug Administration approved as predictors of intracranial lesions on CT after mild traumatic brain injury (mTBI). However, most cases with mTBI are CT negative, and no biomarkers are approved to assist diagnosis in these individuals. In this study, we aimed to determine the optimal combination of blood biomarkers to assist mTBI diagnosis in otherwise healthy adults younger than 50 years presenting to an emergency department within 6 hours of injury.

Although sexuality has been shown to be negatively impacted in up to half of individuals who sustain traumatic brain injury (TBI), few studies have sought to evaluate the efficacy of targeted interventions. Gaining insight into the participant experience of undergoing treatment for post-TBI sexuality changes is a crucial aspect of intervention evaluation. This study aimed to investigate participants with TBI experience of undergoing eight sessions of a novel CBT intervention designed to help both couples and singles improve sexual wellbeing after TBI.
