PRIMARY OBJECTIVE: Alterations to functional connectivity following a traumatic brain injury (TBI) may lead to impaired cognitive performance and major depressive disorder (MDD). In particular, functional gamma band connectivity is thought to reflect information binding important for working memory. The objective of this study was to determine whether altered functional gamma connectivity may be a factor in MDD following TBI (TBI-MDD). RESEARCH DESIGN: This study assessed individuals with TBI-MDD, as well as individuals with TBI alone and MDD alone using electroencephalographic recordings while participants performed a working memory task to assess differences in functional connectivity between these groups...

OBJECTIVE: To investigate the feasibility of a self-advocacy intervention for individuals with acquired brain injury (ABI). DESIGN: Two-arm, parallel-design, randomized feasibility study. METHODS: Twelve participants, 1-year or more post-ABI (TBI and cerebral vascular accident (CVA)), were randomized into treatment/control groups. The treatment group received a group intervention and workbook; the control group received the workbook only. Outcome measures, taken at baseline, post-treatment and 6-weeks follow-up, included the General Self-Efficacy Scale (GSES), Satisfaction with Life Scale (SWLS) and Goal Attainment Scale (GAS) and two exploratory measures developed for the study: the Self Advocacy Scale (SAS) and the Personal Advocacy Activity Scale (PAAS)...

PRIMARY OBJECTIVES: To assess longitudinal trajectories of overall disability after moderate-to-severe traumatic brain injury (TBI) and to examine whether those trajectories could be predicted by socio-demographic and injury characteristics. METHODS: Demographics and injury characteristics of 105 individuals with moderate-to-severe TBI were extracted from medical records. At the 1-, 2-, and 5-year follow-ups, TBI-related disability was assessed by the GOSE. A hierarchical linear model (HLM) was used to examine functional outcomes up to 5 years following injury and whether those outcomes could be predicted by: time, gender, age, relationship, education, employment pre-injury, occupation, GCS, cause of injury, length of post-traumatic amnesia (PTA), CT findings and injury severity score, as well as the interactions between each of these predictors and time...

BACKGROUND: The clinical diagnosis and management of patients with sport-related concussion is largely dependent on subjectively reported symptoms, clinical examinations, cognitive, balance, vestibular and oculomotor testing. Consequently, there is an unmet need for objective assessment tools that can identify the injury from a physiological perspective and add an important layer of information to the clinician's decision-making process. OBJECTIVE: The goal of the study was to evaluate the clinical utility of the EEG-based tool named Brain Network Activation (BNA) as a longitudinal assessment method of brain function in the management of young athletes with concussion...

BACKGROUND: Non-contrast head computer tomography (CT) is widely used to evaluate eligibility of patients after acute traumatic brain injury (TBI) for clinical trials. The NINDS Common Data Elements (CDEs) TBI were developed to standardize collection of CT variables. The objectives of this study were to train research assistants (RAs) to rate CDEs and then to evaluate their performance. The aim was to assess inter-rater reliability (IRR) of CDEs between trained RAs and a neurologist and to evaluate applicability of CDEs in acute and sub-acute TBI to test the feasibility of using CDE CT ratings in future trials and ultimately in clinical practice...

INTRODUCTION: Pulmonary oedema is accumulation of fluid in the lung air spaces and interstitia. Neurogenic pulmonary oedema (NPE) is a potentially life-threatening condition which has been noted in head injury, subarachnoid haemorrhage (SAH), intracerebral haemorrhage (ICH) and others. Timely management is crucial to achieve good outcome; however, no specific guidelines have been defined. METHODS: A 33-year female involved in a motor vehicular accident had a GCS of 14/15 and CT scan showed a moderate-sized unilateral posterior fossa extradural haematoma (PFEDH)...
