INTRODUCTION: Exposure to traumatic brain injury is a core risk factor that predisposes an individual to sporadic neurodegenerative diseases. We provide evidence that mechanical stress increases brain levels of hallmark proteins associated with neurodegeneration. METHODS: Wild-type mice were exposed to multiple regimens of repetitive mild traumatic brain injury, generating a range of combinations of impact energies, frequencies, and durations of exposure. Brain concentrations of amyloid β 1-42 (Aβ1-42), total tau, and α-synuclein were measured by sandwich enzyme-linked immunosorbent assay...

Traumatic spinal cord injury (SCI) is a detrimental condition that causes loss of sensory and motor function in an individual. Many complex secondary injury cascades occur after SCI and they offer great potential for therapeutic targeting. In this study, we investigated the response of endogenous neural progenitor cells, astrocytes, and microglia to a localized thoracic SCI throughout the neuroaxis. Twenty-five adult female Sprague-Dawley rats underwent mild-contusion thoracic SCI (n = 9), sham surgery (n = 8), or no surgery (n = 8)...

Traumatic brain injury (TBI) is characterized by primary damage to the brain from the external mechanical force and by subsequent secondary injury due to various molecular and pathophysiological responses that eventually lead to neuronal cell death. Secondary brain injury events may occur minutes, hours, or even days after the trauma, and provide valuable therapeutic targets to prevent further neuronal degeneration. At the present time, there is no effective treatment for TBI due, in part, to the widespread impact of numerous complex secondary biochemical and pathophysiological events occurring at different time points following the initial injury...

Perceived injustice is a belief that one has been treated unfairly, disrespectfully, and is suffering unnecessarily as a result of another person's actions. Perceived injustice predicts chronic disability after musculoskeletal injury, but to our knowledge, has not been empirically studied in people with mild traumatic brain injuries (MTBIs). We examined perceived injustice and its correlates in patients who were slow to recover from MTBI. Patients (N=102) were recruited from four concussion clinics. The sample was on average 41...

Traumatic Brain Injury (TBI), has been described as the "signature injury" of the Global War on Terror. Explosive blast TBI has become a leading cause of injury as a result of the widespread use of improvised explosive devices in Iraq and Afghanistan. We present a retrospective cross-sectional study of patients with blast-related mild TBI (N=303) seen at the Intrepid Spirit Concussion Recovery Center at Naval Medical Center Camp Lejeune. The objective was to predict outcomes of return to duty (RTD) vs. medical retirement via medical evaluation board (MEB), based on brain imaging, neuropsychological data and history of mTBI...

We seek to elucidate the underlying pathophysiology of injury sustained after mild traumatic brain injury (MTBI) using multi-shell diffusion MRI, deriving compartment-specific WM tract integrity (WMTI) metrics. WMTI allows a more biophysical interpretation of WM changes by describing microstructural characteristics in both intra- and extra-axonal environments. Thirty-two patients with MTBI within 30 days of injury and twenty-one age- and sex-matched controls were imaged on a 3T MR scanner. Multi-shell diffusion acquisition was performed with 5 b-values (250 - 2500 s/mm<sup>2</sup>) along 6 - 60 diffusion encoding directions...

BACKGROUND/AIMS: Patients with mild traumatic brain injury (mTBI) on anticoagulants have an increased risk of intracranial hemorrhage (ICH). However, consensus is lacking on whether to admit them after normal initial cranial CT. We evaluated the yield of 24-h neurological observation. METHODS: Retrospective multicenter study including adult patients admitted over a 5-year period with mTBI on anticoagulation [therapeutic dose heparin, direct oral anticoagulant, or vitamin K antagonist (VKA) with international normalized ratio (INR) ≥ 1...

BACKGROUND: Cerebral edema peaks 36-72 h after moderate traumatic brain injury but thought to be uncommon after mild traumatic brain injury. Post-traumatic headache can develop 48-72 h post-injury, perhaps reflecting the developing cerebral edema. Pseudotumor cerebri can result from various causes, including cerebral edema, and is characterized by increased intracranial pressure, headache, visual, and other common symptoms. Our objective was to report a phenotypically identifiable post-traumatic headache subtype...

Little is known about attention-deficit/hyperactivity disorder (ADHD) in veterans. Practice standards recommend the use of both symptom and performance validity measures in any assessment, and there are salient external incentives associated with ADHD evaluation (stimulant medication access and academic accommodations). The purpose of this study was to evaluate symptom and performance validity measures in a clinical sample of veterans presenting for specialty ADHD evaluation. Patients without a history of a neurocognitive disorder and for whom data were available on all measures (n = 114) completed a clinical interview structured on DSM-5 ADHD symptoms, the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF), and the Test of Memory Malingering Trial 1 (TOMM1) as part of a standardized ADHD diagnostic evaluation...

BACKGROUND: Trauma is an eminently preventable disease. However, prevention programs divert resources away from other priorities. Costing trauma related diseases helps policy makers to make decisions on re-source allocation. We used data from a prospective digital trauma registry to cost Traumatic Brain Injury (TBI) at our institution over a two-year period and to estimate the funding gap that exists in the care of TBI. METHOD: All patients who were admitted to the Pietermaritzburg Metropolitan Trauma Service (PMTS) with TBI were identified from the Hybrid Electronic Medical Registry (HMER)...

Mild blast traumatic brain injury (bTBI) accounts for the majority of brain injury in United States service members and other military personnel worldwide. The mechanisms of primary blast brain injury continue to be disputed with little evidence to support one or a combination of theories. The main hypotheses addressed in this review are blast wave transmission through the skull orifices, direct cranial transmission, skull flexure dynamics, thoracic surge, acceleration, and cavitation. Each possible mechanism is discussed using available literature with the goal of focusing research efforts to address limitations and challenges that exist in blast injury research...

Traumatic brain injury (TBI), as a neurological injury, becomes a leading cause of disability and mortality due to lacking effective therapy. About 75% of TBI is mild traumatic brain injury (mTBI). However, the complex molecular mechanisms underlying mTBI pathophysiology remains to be elucidated. In this study, iTRAQ-based quantitative proteomic approach was employed to measure temporal-global proteome changes of rat brain tissues from different time points (1 day, 7 day and 6 months) post single mTBI (smTBI) and repetitive mTBI (rmTBI)...

Traumatic brain injury (TBI) is a silent epidemic. Mild traumatic brain injury (mTBI) causes brain injury that results in electrophysiologic abnormalities visible on electroencephalography (EEG) recordings. The purpose of this brief review was to discuss the importance of EEG findings in traumatic brain injury. Relevant articles published during the 1996-2016 period were retrieved from Medline (PubMed). The keywords were in English and included "traumatic brain injury", "EEG" and "quantitative EEG". We found 460 articles, analyzed 52 and selected 13 articles...

Mild traumatic brain injury (mTBI) is a common and often inconspicuous wound that is frequently associated with chronic low-grade symptoms and cognitive dysfunction. Previous evidence suggests that daily blue wavelength light therapy may be effective at reducing fatigue and improving sleep in patients recovering from mTBI. However, the effects of light therapy on recovering brain structure remain unexplored. In this study, we analyzed white matter diffusion properties, including generalized fractional anisotropy, and the quantity of water diffusion in isotropic (i...

Mild traumatic brain injury (mTBI) is commonly encountered in clinical practice. While the cognitive ramifications of mTBI are frequently described in the literature, the impact of mTBI on emotional, sensory, and motor function is not as commonly discussed. Chronic pain is a phenomenon more prevalent among patients with mTBI compared to those with moderate or severe traumatic brain injury. Chronic pain can become a primary disorder of the central nervous system (CNS) expressed as widespread pain, and cognitive, mood, and movement dysfunction...

OBJECTIVES: Evaluation of life expectancy (LE) post traumatic brain injury (TBI) is important for planning services for patients and for dealing with medico-legal aspects. We hypothesized that LE for patients who survived 2 years post injury is equal to that of the general population (GP). METHODS: A cohort of 279 patients was assembled during a 5-year period and was followed for 22-27 years. During follow-up, 32 patients (11.5%) died, creating a huge censored data (88...

OBJECTIVES: Military deployment is associated with increased risk of adverse emotional and cognitive outcomes. Longitudinal associations involving posttraumatic stress disorder (PTSD), relatively mild traumatic brain injury (TBI), and neurocognitive compromise are poorly understood, especially with regard to long-term outcomes, and rigorous research is necessary to better understand the corresponding relationships. The objective of this study was to examine short-term and long-term (>5 years) longitudinal associations among PTSD, neurocognitive performance, and TBI following military deployment...

OBJECTIVE: Mild traumatic brain injuries (mTBIs) have frequently been associated with the emergence and persistence of depressive symptoms. However, the factors which contribute to the increased risk for depression after these head injuries remain unclear. Accordingly, we examined the relationship between frequency of self-reported mTBIs and current symptoms of depression and the mediating role of rumination and cognitive flexibility. We also examined whether these relations were moderated by sex differences and the presence of the Val66Met polymorphism in a gene coding for brain-derived neurotrophic factor (BDNF)...
