“…An estimated 1.6 to 3.8 million people suffer from SRC annually in the United States alone (Daneshvar et al 2011;Laker 2015;Langlois et al 2006). SRC occurs in all sports, but incidence rates are highest in contact and collision sports such as football, soccer, rugby, or ice hockey (Guskiewicz et al 2000;Laker 2015;Marar et al 2012;Meehan et al 2010). SRC is characterized by a sudden, but typically, transient impairment in brain function following an impact to the head, face, neck, or body.…”

Sports-related brain injury is very common, and the potential long-term effects include a widerange of neurological and psychiatric symptoms, and potentially neurodegeneration. Aroundthe globe, researchers are conducting neuroimaging studies on primarily homogenoussamples of athletes. However, neuroimaging studies are expensive and time consuming, andthus current findings from studies of sports-related brain injury are often limited by smallsample size. Further, current studies apply a variety of neuroimaging techniques and analysistools which limit comparability among studies. The ENIGMA Sports Injury working group aimsto provide a platform for data sharing and collaborative data analysis thereby leveragingexisting data and expertise. By harmonizing data from a large number of studies from aroundthe globe, we will work towards reproducibility of previously published findings and towardsaddressing important research questions with regard to diagnosis, prognosis, and efficacy oftreatment for sport-related brain injury. Moreover, the ENIGMA Sports Injury working group iscommitted to providing recommendations for future prospective data acquisition to enhancefurther, both, data quality and scientific rigor.

“…Athletes can choose to not report a concussion for various reasons, mainly because they want to keep playing, they do not want to disappoint teammates or coaches, they do not think a concussion is a serious injury, or they do not recognize the signs and symptoms [23][24][25][26]. Indeed, post-concussion symptoms are non-specific [27]. Furthermore, even when athletes report their concussions, an assessment based solely on symptomatology is problematic, as abnormalities in brain function following a concussion may still be present beyond the point of full symptom recovery [28], as well as physiological problems such as imbalance of the ANS [29].…”

Finding reliable biomarkers to assess concussions could play a pivotal role in diagnosis, monitoring, and predicting associated risks. The present study aimed to explore the use of heart rate variability (HRV) in the follow-up of concussions among college athletes and to investigate the relationships between biological sex, symptomatology, and HRV values at baseline and after a concussion. Correlations between measures were also analyzed. A total of 169 (55 females) athletes aged 16 to 22 years old completed baseline testing, and 30 (8 females) concussion cases were followed. Baseline assessment (T1) included psychosocial and psychological questionnaires, symptoms report, and four minutes of HRV recording. In the event of a concussion, athletes underwent re-testing within 72 h (T2) and before returning to play (T3). Baseline findings revealed that girls had higher %VLF while sitting than boys, and a small negligible correlation was identified between %HF and total symptoms score as well as %HF and affective sx. Post-concussion analyses demonstrated a significant effect of time × position × biological sex for %HF, where girls exhibited higher %HF at T3. These findings suggest disruptions in HRV following a concussion and underscore biological sex as an important factor in the analysis of HRV variation in concussion recovery trajectory.

“…The topic of concussion/mild traumatic brain injury (mTBI) has come to the forefront of the clinical vision world due to the constellation of visual problems/visual dysfunctions secondary to sports-related concussions/head injuries, 1,2 and also the recent war efforts. 3 Vision problems are present in thousands of our soldiers and are likely in a similarly large but unknown number of athletes, especially in contact sports such as football, boxing, and soccer.…”

Vision and Reading Deficits in Post-Concussion Patients: A Retrospective Analysis

The prevalence of vision deficits in the pediatric/young adult concussion population in the private optometric practice setting remains unknown. Thus, a retrospective chart review in this area was conducted in the practice of the first author. Twenty-five consecutive patients with a medical diagnosis of concussion received a comprehensive vision and ocular health examination, which also included an objectively-based Visagraph reading assessment and clinical vergence/accommodative facility testing. Three primary categories of oculomotor-based deficits were found: convergence insufficiency (56%), accommodative insufficiency (76%), and oculomotor-based reading dysfunctions (68-82%). The most common symptom was headaches (84%), with 25% of the symptoms related to reading. 68% (15/22) were categorized as reading at least 2 grade levels below their current school grade level for reading eye movements based on the Visagraph findings. These overall findings are consistent with the general oculomotor-based/reading findings in the concussion/mTBI literature. The present results have important practical ramifications regarding the importance of preconcussion baseline oculomotor and Visagraph testing, as well as post-concussion follow-up testing, to help assess a student's ability to return-to-learn (RTL).
