The purpose of this study was to compare global and specific health-related quality of life (HRQOL) throughout concussion recovery between those with and without concussion history. Student-athletes diagnosed with concussion completed global (Short Form-12v2; SF-12) and specific (Hospital Anxiety and Depression Scale: HADS) HRQOL assessments at baseline, 24-48 h, asymptomatic, return-to-play, and 6-months post-injury. Baseline scores were compared to post-injury time points for SF-12 subscores (physical and mental; PCS-12, MCS-12) and HADS subscores (depression and anxiety; HADS-D, HADS-A)...

OBJECTIVE: In clinical and athlete populations, research has found that experiencing a concussion (or traumatic brain injury) is correlated with experiencing other psychiatric conditions, including depression and alcohol problems. However, less is known about concussion comorbidity in other population segments. The purpose of this study is to examine the relationships between concussions and depression symptoms, anxiety symptoms, and hazardous drinking among a large sample of college students (N = 1776) enrolled in a mandatory health course...

The employment of explosive weaponry in modern warfare exposes populations to shock wave-induced and impact-related brain injuries. Among the most common clinical complaints resulting from traumatic brain injury (TBI) are sleep-wake disturbances. The current study assessed the acute effects of mild concussive brain injury (CBI) and mild blast wave-induced brain injury (BTBI) on mouse behavior and orexin-A expression. Male C57BL/6J mice were exposed to CBI, BTBI, or sham procedures. Injured animals and their shams were further divided into the following subgroups: 24-h survival in standard group (SG) housing, 72-h survival in SG housing, and 72-h survival in Any-Maze cages (AMc)...

Due to the unmet need for a means to study chronic traumatic encephalopathy (CTE) in vivo, there have been numerous efforts to develop an animal model of this progressive tauopathy. However, there is currently no consensus in the field on an injury model that consistently reproduces the neuropathological and behavioral features of CTE. We have implemented a repetitive Closed-Head Impact Model of Engineered Rotational Acceleration (CHIMERA) injury paradigm in human transgenic (hTau) mice. Animals were subjected to daily subconcussive or concussive injuries for 20 days and tested acutely, 3 months, and 12 months post-injury for deficits in social behavior, anxiety, spatial learning and memory, and depressive behavior...

Concussion in athletes can contribute to early neuropsychological changes that may be indicative of future neurodegenerative disease. One of the hallmark findings of chronic traumatic encephalopathy is anxiety and impulsive behavior that often develops early in the course of the disease. The behavioral dysfunction can be grouped into a broader category referred to as cognitive disruption. The current gold standard for diagnosing chronic neurodegeneration is post-mortem evaluation of tauopathy to identify neurofibrillary tau tangles in neurons...

A significant proportion of children and adolescents report psychological distress following concussion, but little is known about the predictors of these problems. The purpose of this study was to examine predictive factors of psychological distress following pediatric concussion. It was hypothesized that the presence of pre-injury psychological distress would be the strongest predictor of psychological distress post-concussion, with other demographic and acute injury factors adding incrementally to prediction...

INTRODUCTION: Research has indicated that athletes who engage in high-risk athletic activities, such as football and hockey, have riskier personalities than their low-risk and nonathlete counterparts (Ahmadi et al., 2011, Procedia Soc Behav Sci, 30 and 247-251; Zuckerman, 1983, Biological bases of sensation seeking, impulsivity, and anxiety, Lawrence Erlbaum Assoc Inc.). For instance, increased sensation-seeking and aggression are common in high-risk athletes, rendering these individuals more likely to sustain a subsequent injury, such as concussion...

The effects of soccer-related head impacts, beyond overt concussions, on Patient Reported Outcomes (PROs) have not been explored to date. Generalized estimating equations were employed to determine the association between soccer-related head impacts (headers in the prior 2 weeks, unintentional head impacts in the prior 2 weeks, headers in the prior 12 months and lifetime concussions) on PROs including depression, anxiety, sleep disturbance and sleep impairment. Compared to players with no unintentional head impacts in the prior 2 weeks, players with one unintentional exposure reported more symptoms of anxiety (p = 0...

A 31-year old women presented with excessive startle reflex and frequent falls. Her startle reflex is induced by slight stimuli which are not problematic in most people. Soon after her startle reflex is evoked, generalized muscle stiffness occurs. She becomes rigid and falls down without loss of consciousness. Because she cannot protect herself when she is startled and falls, she has repeatedly bruised her head and face. The pedigree includes her father and two sisters with similar symptoms. Gene analysis revealed GLRA1 mutation, and she was diagnosed with hereditary hyperekplexia (HPX)...

REVIEW
Amir M Molaie, Jamie Maguire
Neuropsychiatric symptoms following traumatic brain injury (TBI) are common and contribute negatively to TBI outcomes by reducing overall quality of life. The development of neurobehavioral sequelae, such as concentration deficits, depression, anxiety, fatigue, and loss of emotional well-being has historically been attributed to an ambiguous "post-concussive syndrome," considered secondary to frank structural injury and axonal damage. However, recent research suggests that neuroendocrine dysfunction, specifically hypopituitarism, plays an important role in the etiology of these symptoms...

Background: Increases in the quantity or impact of noradrenergic signaling have been implicated in the pathophysiology of posttraumatic stress disorder (PTSD). This increased signaling may result from increased norepinephrine (NE) release, from altered brain responses to NE, or from a combination of both factors. Here, we tested the hypothesis that Veterans reporting a history of trauma exposure would show an increased association between brain NE and mental health symptoms commonly observed after trauma, as compared to Veterans who did not report a history of trauma exposure, consistent with the possibility of increased brain reactivity to NE after traumatic stress...

BACKGROUND AND PURPOSE: Postural orthostatic tachycardia syndrome (POTS) is increasingly recognized as a complication affecting recovery from concussion. Individuals with POTS demonstrate refractory dizziness, lightheadedness, cognitive dysfunction, fatigue, headache, chronic pain, nausea and gastrointestinal dysmotility, activity and exercise intolerance, syncope, and tachycardia. Subtypes of POTS may include hypovolemia, hyperadrenergic states, autonomic neuropathy, and underlying autoimmunity, which may variably impact response to rehabilitation in varying ways...
