81 de articoleUniversity of Otago research published in the Journal of Biomechanics demonstrates that smart mouthguard systems use standardized models that fail to account for biological variation across different sexes, ages, and body sizes. This limitation may result in serious traumatic brain injuries being undetected during impact assessment in rugby players.
This scoping review examined 10 studies investigating how mild traumatic brain injury (mTBI) affects brain functional connectivity measured via EEG in children. Five studies found significant differences between mTBI and control groups, with Brain Network Analysis proving more effective for tracking changes over time than alternative methods.
The CDC developed a tiered case definition for self-reported traumatic brain injury (TBI) to improve national surveillance, addressing limitations of hospital-based data that undercount TBIs occurring in outpatient and untreated settings. This surveillance system aims to better estimate the public health burden of concussion and TBI across all causes of brain injury in the United States.
This CDC study examined 3,557 children aged 5-17 years and found 9.9% sustained a TBI in the past year, with specific symptoms (sleep changes, concentration difficulty, light/noise sensitivity, learning difficulties) associated with worse school outcomes. Findings support school-based accommodations and graduated academic support to facilitate successful return-to-learn after TBI.
This article critically examines divergent diagnostic criteria for mild traumatic brain injury (mTBI) used across clinical and forensic settings, including ACRM, VA/DoD, DSM-5-TR, ICD-11, and CISG frameworks, highlighting their differing evidentiary standards and practical limitations. The authors review evidence-based approaches to diagnostic uncertainty, emerging blood biomarkers (GFAP, UCH-L1, NfL, S100B), and the scope of neuropsychological opinion in legal contexts, addressing challenges in retrospective determination and mechanistic complexity in injury mechanisms.
This retrospective cohort study analyzed Medicare claims data (2010-2017) to assess how concurrent traumatic brain injury affects recovery outcomes in elderly patients hospitalized for hip fracture. Among 101,196 beneficiaries, those with TBI (3.1%) had higher mortality and fewer days spent at home during the 12-month follow-up period, despite being older with greater comorbidity burden.
This narrative review examines how mild traumatic brain injury (mTBI) affects the hypothalamic-pituitary-ovarian axis, particularly in females who experience disproportionately worse outcomes and higher rates of menstrual dysfunction post-injury. The authors synthesize evidence on sex differences, pituitary hormone regulation, and downstream reproductive health consequences to identify research gaps and clinical recommendations for female mTBI patients.
A cross-sectional survey of 524 Saudi Arabian parents assessed their knowledge and attitudes regarding pediatric concussions, revealing moderate concussion knowledge (average 15.4/25) and positive attitudes (42.0/49) despite 63% lacking prior awareness. Sociodemographic factors including education level, income, and parental history of head injuries were examined as potential influencers of concussion management understanding and symptom recognition.
This study investigates the relationship between substance use disorders and traumatic brain injury outcomes in a rural trauma center population. The research examines epidemiological patterns and clinical evidence linking substance use to TBI incidence and recovery outcomes.
This multicenter study externally validated the UPFRONT-model, which predicts functional outcome after mild traumatic brain injury using factors like educational level, consciousness level, neck pain, and psychological variables. The model demonstrated acceptable discrimination ability but systematically underestimated recovery rates (predicted 46% vs observed 75%), suggesting need for calibration adjustments while confirming psychological variables as robust predictors.
This study examines the epidemiology of concussions across the U.S. population using health insurance claims data to identify incidence rates and patterns. The research provides insights into the burden and frequency of concussion injuries across different demographics and settings.
This study examined the relationship between pupil light response dynamics and accommodation deficits in 17 individuals with prior mild TBI using objective measurements. Participants with accommodative dysfunction showed significantly larger pupil constriction amplitudes and faster constriction velocity, suggesting a neurophysiological link between these two oculomotor functions post-TBI.
This scoping review systematically examined 32 studies (25 animal, 7 human) on ketogenic therapies for traumatic brain injury, synthesizing mechanistic insights and clinical outcomes. The analysis identifies sex imbalances in TBI research and evaluates barriers to clinical implementation of ketogenic interventions as a potential therapeutic strategy.
A study examines the relationship between documented concussions sustained by NFL players and subsequent arrest outcomes, using professional football as a model for understanding head injury consequences. The research investigates how repeated concussive and subconcussive impacts in contact sports may be associated with behavioral and legal problems in affected athletes.
This study examined 913 adolescents with concussions using network analysis to identify how postconcussion symptoms interconnect and cluster within predefined clinical profiles. Key findings identified vestibular (dizziness) and cognitive/fatigue symptoms as central nodes, with ocular and migraine symptoms serving as important bridges linking symptom clusters.
This cross-sectional study of 1,085 former professional American football players examined whether concussion history associates with tinnitus and whether tinnitus mediates relationships between head injury exposure and mental health outcomes. Greater concussion symptom history was significantly associated with increased odds of tinnitus, with implications for understanding post-TBI auditory and neurobehavioral complications.
An 18-year-old professional goalkeeper sustained a significant head injury with intracranial hemorrhage and microhemorrhages confirmed on CT and MRI imaging. Conservative management including prolonged rest, neurocognitive assessment, and structured graduated return-to-sport led to successful recovery without symptom recurrence at six months.
A retrospective study of 53 patients (39 with migraine aura, 14 with TIA) investigated whether oxygen extraction fraction (OEF) measurements from MRI perfusion imaging could differentiate between these two conditions. Patients with migraine aura showed significantly higher OEF values than TIA patients, with the OEF ratio achieving 0.89 area under the curve for discrimination.
