Acquired brain injury (ABI) is a major public health problem in Massachusetts (Hackman et al, 2014) and includes traumatic brain injury (TBI), stroke, ABI-related infectious diseases, metabolic disorders affecting the central nervous system (brain and spinal cord), and brain tumor. Advances in emergency medical care and neurosurgery mean that more people are surviving severe traumatic brain injury (Trexler et al, 2014). Yet many patients with severe TBI in particular, are not receiving inpatient services after initial treatment (Hackman et al, 2014; CDC, 2014) or later that are known to be effective (Malec & Kean, 2015; Lewis & Horn, 2015; BI Commission, 2011; Kolakowsky-Hayner et al, 2000; Interviews)...

BACKGROUND AND PURPOSE: To evaluate the effect of patient sex and type of activity on concussion assessment and management recommendations. METHODS: We administered a web-based survey to all nurse practitioners (NPs) actively licensed in Washington and Oregon. Participants were randomized to view one of four standardized patient scenario videos of an adolescent seeking care for a concussion, portraying the same symptomology but differing by sex and activity (soccer/hiking)...

: Mitochondria play a variety of functional roles in cortical neurons, from metabolic support and neuroprotection to the release of cytokines that trigger apoptosis. In dendrites, mitochondrial structure is closely linked to their function, and fragmentation (fission) of the normally elongated mitochondria indicates loss of their function under such pathological conditions as stroke and brain trauma. Using in vivo two-photon microscopy in mouse brain, we quantified mitochondrial fragmentation in a full spectrum of cortical injuries ranging from severe to mild...

Accurate means to detect mild traumatic brain injury (mTBI) using objective and quantitative measures remain elusive. Conventional imaging typically detects no abnormalities despite post-concussive symptoms. In the present study, we recorded resting state magnetoencephalograms (MEG) from adults with mTBI and controls. Atlas-guided reconstruction of resting state activity was performed for 90 cortical and subcortical regions, and calculation of inter-regional oscillatory phase synchrony at various frequencies was performed...

PURPOSE: This study aims to investigate the short-term efficacy and tolerability of immediate-release methylphenidate (IR-MPH) in children with a history of traumatic brain injury (TBI). METHODS: Twenty children with TBI (mean age: 12.7±3.1years) who had clinically significant attention deficit and/or hyperactivity-impulsivity symptoms and twenty children with primary Attention Deficit Hyperactivity Disorder (ADHD) (mean age: 12.3±3.05years) were included. Study measures, which included the Turgay DSM-IV based ADHD rating Scale (T-DSM-IV-S), Conners' Parent Rating Scale (CPRS), Conners' Teacher Rating Scale (CTRS-R) and Clinical Global Impression-Improvement Scale (CGI-I), were completed at the baseline for both of the groups...

Traumatic brain injury (TBI) is common in both military and civilian populations, and often results in neurobehavioral sequelae that impair quality of life in both patients and their family. Although individuals who are chronically exposed to stress are more likely to experience TBI, it is still unknown whether pre-injury stress influences the outcome after TBI. The present study tested whether behavioral and cognitive long-term outcome after TBI in rats is affected by prior exposure to an innate stress stimulus...

BACKGROUND AND OBJECTIVE: Posttraumatic headache (PTH) is one of the most common, debilitating and difficult symptoms to manage after a mild traumatic brain injury, or concussion. However, the mechanisms underlying PTH remain elusive, in part due to the lack of a clinically relevant animal model. Here, we characterized for the first time, headache and pain-related behaviours in a rat model of concussion evoked by a mild closed head injury (mCHI) - the major type of military and civilian related trauma associated with PTH - and tested responses to current and novel headache therapies...

Approximately 20% of current-era Veterans have sustained a traumatic brain injury (TBI), which can result in persistent postconcussive symptoms. These symptoms may disrupt family and social functioning. We explored psychiatric, postconcussive, and cognitive factors as correlates of objective functioning and subjective satisfaction in family and social relationships. At entry into a supported employment study, 50 unemployed Veterans with a history of mild to moderate TBI and current cognitive impairment were administered baseline assessments...

We present the case of an adult male who sustained Todd's paresis after a traumatically induced seizure in a patient with an isolated facial injury. The precipitating event was head trauma from a golf club. The patient had no previous history of seizures and went on to make a complete neurologic recovery with no cerebral pathology noted. A literature review suggests that Todd's paresis after trauma is very rare as opposed to occurring in the medical or long-term brain injury settings. Although the authors acknowledge that it may occur in trauma, the awareness within the prehospital setting is sufficiently rare for this case report to be of interest to prehospital clinicians; it is important prehospital clinicians are aware of this condition...

BACKGROUND: Traumatic brain injury (TBI) is a debilitating medical and emerging public health problem that is affecting people worldwide due to a multitude of factors including both domestic and war-related acts. The objective of this paper is to systematically review the status of TBI in Lebanon - a Middle Eastern country with a weak health system that was chartered by several wars and intermittent outbursts of violence - in order to identify the present gaps in knowledge, direct future research initiatives and to assist policy makers in planning progressive and rehabilitative policies...

Traumatic brain injury (TBI) has chronic and long term consequences for which there are currently no approved pharmacological treatments. We have previously characterized the chronic neurobehavioral and pathological sequelae of a mouse model of repetitive mild TBI (r-mTBI) to two years post-TBI. Despite the mild nature of the initial insult, secondary injury processes are initiated which involve neuroinflammatory and neurodegenerative pathways persisting and progressing for weeks and months post-injury and providing a potential window of opportunity for therapeutic intervention...

Over the past decade, concussion has become the most widely discussed injury in contact sports. However, concussions also occur in several other settings, such as non-contact sports, elderly individuals, young children, military personnel, and victims of domestic violence. Concussion is frequently undiagnosed as a cause of psychiatric morbidity, especially when the patient has no history of loss of consciousness or direct head trauma. Almost all of the extant literature focuses on traumatic brain injury and assumes that concussion is merely a mild form of traumatic brain injury, which has resulted in a lack of understanding about what concussion is, and how to diagnose, monitor, and treat its varied neuropsychiatric symptoms...

Those who have suffered a concussion, otherwise known as a mild traumatic brain injury (mTBI), often complain of lingering memory problems. However, there is little evidence in the behavioral literature reliably demonstrating memory deficits. Thus, in the present study, cognitive profiles including measures of general executive functioning and processing speed, as well as episodic and semantic memory were collected in younger and older adult participants with or without a remote (>1year prior to testing) mTBI...

Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease associated with repetitive mild impact traumatic brain injury from contact sports. Recently, a consensus panel defined the pathognomonic lesion for CTE as accumulations of abnormally hyperphosphorylated tau (p-tau) in neurons (neurofibrillary tangles), astrocytes and cell processes distributed around small blood vessels at sulcal depths in irregular patterns within the cortex. The pathophysiological mechanism for this lesion is unknown. Moreover, a subset of CTE cases harbors cortical β-amyloid plaques...

Mild traumatic brain injury (mTBI) is the signature injury in warfighters exposed to explosive blasts. The pathology underlying mTBI is poorly understood, as this condition is rarely fatal and thus postmortem brains are difficult to obtain for neuropathological studies. Here we report on studies of an experimental model with a gyrencephalic brain that is exposed to single and multiple explosive blast pressure waves. To determine injuries to the brain resulting from the primary blast, experimental conditions were controlled to eliminate any secondary or tertiary injury from blasts...

BACKGROUND: In total, 3.8 million concussions occur each year in the US leading to acute functional deficits, but the underlying histopathologic changes that occur are relatively unknown. In order to improve understanding of acute injury mechanisms, appropriately designed pre-clinical models must be utilized. METHODS: The clinical relevance of compression wave injury models revolves around the ability to produce consistent histopathologic deficits. Mild traumatic brain injuries activate similar neuroinflammatory cascades, cell death markers and increases in amyloid precursor protein in both humans and rodents...

PURPOSE: Traumatic brain injury is considered the main cause of hypopituitarism in adults, and GH deficiency appears to be the most frequent pituitary deficit. Most of the available studies have included all degrees of severity of trauma. We aimed to assess pituitary function and GH deficiency in adult patients at different time lengths after complicated mild TBI according to Glasgow Coma Scale. We also aimed to evaluate whether mild TBI patients with GH deficiency had developed alterations in the glycolipid profile...

Neural input to the immune system can alter its ability to clear pathogens effectively. Patients suffering mild traumatic brain injury (mTBI) have shown reduced rates of pneumonia and a murine model replicated these findings, with better overall survival of TBI mice compared with sham-injured mice. To further investigate the mechanism of improved host response in TBI mice, this study developed and characterized a mild tail trauma model of similar severity to mild TBI. Both mild tail trauma and TBI induced similar systemic changes that normalized within 48 hours, including release of substance P...
