REVIEW
Robert Eme
Traumatic brain injury outcomes can be classified as acute or chronic. Acute outcomes refer to injuries that occur immediately at the time of the injury and subsequent short-term consequences. Chronic outcomes refer to adverse outcomes that are more long-term. In mild traumatic brain injury, recovery from acute outcomes typically occurs very rapidly, i.e., within 2 weeks, with full recovery expected by 90 days. However, some 10%-15% individuals can remain symptomatic for much longer with an outcome termed post-concussive syndrome...

OBJECTIVE: A bi-modal visual processing model is supported by research to affect dysfunction following a traumatic brain injury (TBI). TBI causes dysfunction of visual processing affecting binocularity, spatial orientation, posture and balance. Research demonstrates that prescription of prisms influence the plasticity between spatial visual processing and motor-sensory systems improving visual processing and reducing symptoms following a TBI. RATIONALE: The rationale demonstrates that visual processing underlies the functional aspects of binocularity, balance and posture...

Emerging evidence indicates that repetitive head impacts, even at a sub-concussive level, may result in exacerbated or prolonged neurologic deficits in athletes. This study aimed to: 1) quantify the effect of repetitive head impacts on the alteration of neuronal activity based on fMRI of working memory after a high school football season; and 2) determine whether a neck collar that applies mild jugular vein compression to reduce brain energy absorption in head impact through slosh mitigation can ameliorate the altered fMRI activation during a working memory task...

We investigated potential brain volumetric differences in a sample of former high school football players many years after these injuries. Forty community-dwelling males ages 40-65 who played high school football, but not college or professional sports, were recruited. The experimental group (n = 20) endorsed experiencing two or more mTBIs on an empirically validated mTBI assessment tool (median = 3, range = 2-15). The control group (n = 20) denied ever experiencing an mTBI. Participants completed a self-report index of current mTBI symptomatology and underwent high-resolution T1-weighted MRI scanning, which were analyzed using the Freesurfer software package...

Objective: This study examined the effects of total and partial sleep deprivation on subjective symptoms and objective neurocognitive performance, as measured by the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) in a sample of healthy adults. Method: One-hundred and two, right-handed, healthy participants (between ages 18 and 30 years old) completed three consecutive nights in the sleep laboratory with concurrent continuous polysomnography monitoring...

The Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) is a computerized neuropsychological test battery commonly used to assess cognitive functioning after a concussion. It is recommended that application of ImPACT utilizes a baseline administration so athletes have an individualized baseline with which to compare post-injury results should they sustain a concussion. It has been suggested that athletes may provide suboptimal effort, called "sandbagging," in order to return to their baseline cognitive scores, and thus to play, more quickly...

OBJECTIVE: Youth with attention deficit hyperactivity disorder (ADHD) perform more poorly on preseason cognitive testing and report more baseline concussion-like symptoms but prior studies have not examined the influence of medication use on test performance or symptom reporting. This study investigated whether medication use is relevant when interpreting baseline ImPACT® results from student athletes with ADHD. METHOD: Participants were 39,247 adolescent athletes, ages 13-18 (mean age = 15...

Objective We describe an apparently unique case of an extra-uterine leiomyoma in the cervical paraspinus including its evaluation and management. Methods A 14-year-old girl was referred to the neurology clinic for an abnormal head CT following a concussion. MRI revealed a homogenously enhancing left cervical paraspinal mass. The patient underwent complete resection and subsequent genetic testing and counseling were obtained to determine the presence of Li-Fraumeni Syndrome (LFS) or Hereditary Leiomyomatosis and Renal Cell Cancer (HLRCC) mutations...

Concussion induces transient, and oftentimes chronic, lingering impairment to mental functioning, which must be driven by some underlying neurobiological perturbation - however, the physical changes related to sequelae are difficult to detect. Previous imaging studies on concussion have focused on alterations to cortical anatomy, but few have examined the cerebrum, subcortex, and cerebellum. Here, we present an analysis of these structures in a single cohort (all males, 21 patients, 22 controls) using MRI and diagnosed with a single-concussive episode in the acute and sub-acute stages of injury...

OBJECTIVE: In this paper, we describe the development of a novel tool-the Sports Organization Concussion Risk Assessment Tool (SOCRAT)-to assist sport organizations in assessing the overall risk of concussion at a team level by identifying key risk factors. METHODS: We first conducted a literature review to identify risk factors of concussion using ice hockey as a model. We then developed an algorithm by combining the severity and the probability of occurrence of concussions of the identified risk factors by adapting a risk assessment tool commonly used in engineering applications...

SETTING: Emergency department. PARTICIPANTS: Children aged 2 to 12 years presenting with either a concussion or minor bodily injury (control).

Nasal fractures represent approximately 60% of all maxillofacial injuries that occur in athletic activities; however, there are no current guidelines regarding immediate sideline management of these injuries. Therefore, the purpose of this article was to (1) summarize the anatomy, etiology, and incidence of nasal fractures, and (2) evaluate the current body of literature regarding immediate on-field and subsequent outpatient management. It is imperative to establish that the athlete's airway is not compromised and there are no other severe concomitant injuries, such as a concussion, ocular injury, or leakage of cerebrospinal fluid...

For several years both cognitive and physical rest remained at the forefront in pediatric postconcussion management. However, the concept of "rest" has not been well defined and there remains significant variability both in terms of rest recommendations provided as well as adherence to such recommendations. More recently, there has been growing evidence to suggest that an earlier return to light or moderate activity is not detrimental and may, in fact, facilitate symptomatic improvement, thereby highlighting a new role for active rehabilitation in recovery from concussion...

Repetitive mild traumatic brain injury (rmTBI; e.g., sports concussions) is common and results in significant cognitive impairment. Targeted therapies for rmTBI are lacking, though evidence from other injury models indicates that targeting N-methyl-d-aspartate (NMDA) receptor (NMDAR)-mediated glutamatergic toxicity might mitigate rmTBI-induced neurologic deficits. However, there is a paucity of preclinical or clinical data regarding NMDAR antagonist efficacy in the rmTBI setting. To test whether NMDAR antagonist therapy improves outcomes after rmTBI, mice were subjected to rmTBI injury (4 injuries in 4 days) and randomized to treatment with the NMDA antagonist memantine or with vehicle...

A history of repeated concussion has been linked to the later development of neurodegeneration, which is associated with the accumulation of hyperphosphorylated tau and the development of behavioral deficits. However, the role that exogenous factors, such as immune activation, may play in the development of neurodegeneration following repeated mild traumatic brain injury (rmTBI) has not yet been explored. To investigate, male Sprague-Dawley rats were administered three mTBIs 5 days apart using the diffuse impact-acceleration model to generate ∼100G...
