Sport-related concussion has been shown to alter cerebral blood flow (CBF) both acutely and chronically, and may exert cumulative effects across multiple injuries. Such dysfunction may be mediated by trauma-induced deficits to CBF control mechanisms, though our understanding of these effects is limited, including dynamics of neurovascular coupling (NVC) responses (i.e. CBF responses to neurologic demand). 179 junior-level contact sport athletes completed preseason testing - 42 reported never having experienced a concussion (Hx-) while 31 had endured three or more (Hx3+)...

BACKGROUND: Clinicians typically rely on neuropsychological and balance tests to track concussion recovery. The aforementioned tests imply impairments that are based on performance, but these tests do not directly measure brain physiology throughout concussion recovery. Because of these issues, an objective biomarker that can index severity and the recovery timeline is needed. Moreover, the number of concussions occurring at a recreational level requires the biomarker to be easily administered in a cost effective manner, and the results easily interpreted...

A concussion is a relatively common sports-related injury that affects athletes of all ages. Although not expected to replace sports medicine physicians and neurologists with regard to the management of concussions, orthopaedic surgeons, particularly those who are fellowship-trained in sports medicine, must have a current knowledge base of what a concussion is, how a concussion is diagnosed, and how a concussion should be managed. Orthopaedic surgeons should understand the pathophysiology, assessment, and management of concussion so that they have a basic comprehension of this injury that is at the forefront of the academic literature and North American media...

BACKGROUND: Observational research has linked altitude to concussion risk, but the physiologic and epidemiologic bases for this association remain questionable. METHODS: We performed a retrospective cohort study by analyzing four seasons of NFL data from a widely used database (Concussion Watch) to determine if previous claims that altitude ≥196m reduced concussion risk were replicable and whether an arbitrary predictor variable (animal vs. non-animal team logo) was related to concussion risk...

CONTEXT:   Concussions in student-athletes are a serious problem. Most states have enacted legislation mandating concussion education for student-athletes, under the assumption that education leads to better self-reporting of concussions and improved knowledge of symptoms. OBJECTIVE:   (1) To determine the effect of state-based concussion legislation on the proportion of student-athletes receiving concussion education and to assess the moderation of this effect by gender and sport and (2) to assess the effect of concussion education on student-athletes' knowledge of concussion symptoms and likelihood of seeking treatment after a concussion...

Sports-related concussions are receiving growing attention in healthcare. Most concussions resolve spontaneously with little or no treatment, but twenty percent of concussions take longer than three weeks to resolve. In some cases, symptoms can last for five years following a traumatic brain injury. Physical Therapists have unique skills that can assist patients experiencing protracted recovery. The purpose of this clinical commentary is to describe a new conceptual model that provides a framework for Physical Therapy management of patients with protracted recovery following a sports-related concussion...

Sports-related concussions lead to persistent anomalies of the brain structure and function that interact with the effects of normal ageing. Although post-mortem investigations have proposed a bio-signature of remote concussions, there is still no clear in vivo signature. In the current study, we characterized white matter integrity in retired athletes with a history of remote concussions by conducting a full-brain, diffusion-based connectivity analysis. Next, we combined MRI diffusion markers with MR spectroscopic, MRI volumetric, neurobehavioral and genetic markers to identify a multidimensional in vivo signature of remote concussions...

A subset of patients experience persistent symptoms after pediatric concussion, and magnetic resonance imaging (MRI) is commonly used to evaluate for pathology. The utility of this practice is unclear. We conducted a retrospective cohort study to describe the MRI findings in children with concussion. A registry of all patients seen at our institution from January 2010 through March 2016 with pediatric sports-related concussion was cross-referenced with a database of radiographic studies. Radiology reports were reviewed for abnormal findings...
