The recent passage of state youth sports concussion laws across the country introduces clinical implications for health care professionals caring for student-athletes. Although the laws were established to provide protections for student-athletes and prevent adverse outcomes, efforts aimed at implementation have uncovered various challenges in concussion diagnosis and management. Some of the most salient issues include medical evaluation, return to play, and return to learn. For this reason, health care professionals play a pivotal role in determining the critical next steps after a student is removed from play with a suspected concussion...

A 19-year-old man was sent to the emergency department following a pitch-side assessment for suspected concussion, unexplained upper abdominal tenderness and vomiting, following a high-impact tackle during a rugby match. A Focussed Assessment with Sonography for Trauma (FAST) scan performed in the emergency department suggested intra-abdominal free fluid, and subsequent head and abdominal CT imaging showed no intracranial lesion but confirmed a significant haemoperitoneum due to large splenic tear and bleeding...

With concussion rates on the rise for football players, there is a need for further research to increase skills and decrease injuries. Behavioral skills training is effective in teaching a wide variety of skills but has yet to be studied in the sports setting. We evaluated behavioral skills training to teach safer tackling techniques to six participants from a Pop Warner football team. Safer tackling techniques increased during practice and generalized to games for the two participants who had opportunities to tackle in games...

BACKGROUND: Headache disorders are exceedingly common, debilitating neurological conditions, and there is a striking paucity of headache specialists nationally. However, headache education is underrepresented in the curriculum of neurology residency programs and few neurology residents elect to pursue headache medicine fellowships. We aimed to explore the possibility that a low degree of headache interest among neurology department chairs and residency program directors (PDs) underlies this mismatch...

Rebecca Wiseheart, Robin Wellington
Learning disability (LD) has been identified as a potential risk factor for protracted recovery from a sport-related concussion, yet students with LD are rarely included in concussion research. Here, we draw special attention to dyslexia, a common but often underdiagnosed LD. Reading and learning problems commonly associated with dyslexia are often masked by protective factors, such as high verbal ability or general intelligence. Hence, high-achieving individuals with dyslexia may not be identified as being in a high-risk category...

Computerized neurocognitive tests (CNTs) are widely used at all competitive levels of sport to assess sport concussion (SC). Whereas there are multiple CNTs available, little is known about how some of the most popular platforms compare. The purpose of this study was to investigate the test-retest reliability of the Automated Neuropsychological Assessment Metrics (ANAM), Concussion Vital Signs (CVS) and the Immediate Postconcussion and Cognitive Testing battery (ImPACT) using clinically relevant time points in healthy college-age participants...

Concussion in sport is often underdiagnosed with the potential risk of long-term sequelae. This article presents the mechanisms, the underlying pathophysiology and typical primary signs and symptoms. The recognition and resulting medical measures including the present recommendations and decisions on return to play are described. The majority of patients with concussion present with clinical and cognitive symptoms only for short time intervals. As a rule a complete subjective recovery is observed within a few hours or days...

BACKGROUND: Concussion rates have increased significantly over the past decade. This may reflect an increase in the knowledge and diagnosis of the symptoms of a concussion rather than a true increase in the incidence. Assessing trends in the way that concussions are presenting to and being identified by clinicians over the same period may provide additional insight into the apparent rise in concussions. PURPOSE: To evaluate patterns of change in concussion symptom presentation, diagnostic/evaluation methods, and symptom resolution time reported for United States high school athletes from the 2007-2008 through 2014-2015 academic years...

Approximately 1.6 to 3.8 million recreational and sports-related concussions (SRC) occur each year in the Unites States. Research suggest that female athletes are at a greater risk for a SRC compared to male athletes competing in comparable sports (i.e., soccer, basketball). Moreover, female athletes have reported more total symptoms and greater neurocognitive impairments following a SRC. Female athletes have been found to report greater symptom provocation as measured by the Vestibular/Ocular Motor Screening (VOMS), and increased brain activation compared to males...

Our understanding of the diverse physiological manifestations of concussion is changing rapidly. This has an influence on the clinical assessment of patients who have sustained a concussion. The 2017 Consensus Statement on Concussion in Sport states that numerous post-injury clinical findings, such as cognitive deficits, post-traumatic headaches, dizziness, difficulties with oculomotor function, and depression have all been associated with a poorer prognosis in concussed patients. This demonstrates that there are several potential clinical manifestations after head injury warranting clinical evaluation...

BACKGROUND: Mild traumatic brain injury (mTBI) is a leading cause of sustained impairments in military service members, Veterans, and civilians. However, few treatments are available for mTBI, partially because the mechanism of persistent mTBI deficits is not fully understood. METHODS: We used magnetoencephalography (MEG) to investigate neuronal changes in individuals with mTBI following a passive neurofeedback-based treatment programme called IASIS. This programme involved applying low-intensity pulses using transcranial electrical stimulation (LIP-tES) with electroencephalography monitoring...

Traumatic brain injury (TBI) increases the risk of Alzheimer's disease (AD). Calpain activation and tau hyperphosphorylation have been implicated in both TBI and AD. However, the link between calpain and tau phosphorylation has not been fully identified. We recently discovered that the two major calpain isoforms in the brain, calpain-1 and calpain-2, play opposite functions in synaptic plasticity and neuronal survival/death, which may be related to their different C-terminal PDZ binding motifs. Here, we identify the tyrosine phosphatase PTPN13 as a key PDZ binding partner of calpain-2...
