Abstract
INTRODUCTION The purpose of this study was to determine if the time interval between two concussive events influences the number of days to asymptomatic status, days to return to play, or performance on common post-concussion assessments following the second concussion. METHODS Data from 448 collegiate athletes and service academy cadets with two concussions (time between concussions: median 295.0 days [interquartile range: 125.0-438.2]), 40.0% female) were analyzed from Concussion Assessment Research and Education (CARE) Consortium institutions between 2014 and 2020. Days between concussions was the primary predictor variable. Primary outcome measures included time to asymptomatic and time to return to play following the second concussion. Secondary outcome measures included total number of symptoms, total symptom severity, Balance Error Scoring System total score, and Standardized Assessment of Concussion total score within 48 h of their second concussion. RESULTS Time between concussions did not significantly contribute to the multivariate time to asymptomatic (p = 0.390), time to return to play (p = 0.859), or the secondary outcomes (p-range = 0.165-0.477) models. Time to asymptomatic (p = 0.619) or return to play (p = 0.524) did not differ between same-season and different-season concussions. Sex significantly contributed to the return to play (p = 0.005) multivariate model. Delayed symptom onset and immediate removal from play/competition significantly contributed to the total number of symptoms (p = 0.001, p = 0.014) and symptom severity (p = 0.011, p = 0.022) multivariate models. CONCLUSION These results suggest that in a population with a large period between injuries, the time between concussions may not be relevant to clinical recovery.

Abstract
OBJECTIVE The purpose of this study was to assess changes in concussion knowledge and attitudes amongst incoming intercollegiate student-athletes over the course of a decade (2010-2012 vs 2021-2023). METHODS There were 592 student-athletes from 2 cohorts (2010-2012, 2021-2023) who completed the Rosenbaum Concussion Knowledge and Attitudes Survey (ROCKaS) questionnaire which is comprised of a concussion knowledge index (CKI, 0-24) and attitude index (CAI, 15-75) with higher scores reflecting better performance. A three factor ANOVA (Group, Sex, Concussion History) compared performance on the CKI and CAI. Individual questions were compared between groups with a Chi-Square analysis. RESULTS For the CKI, there was a significant main effect for Group (2010-2012: 18.5 ± 2.6, 2021-2023: 19.4 ± 2.5, p < 0.001, η 2 = 0.032 ) . For the CAI, there was also a significant main effect for group (2010-2012: 52.9 ± 6.0, 2021-2023: 62.2 ± 6.5, p < 0.001, η 2 = 0.359 ) . CONCLUSIONS The results of this study show a modest increase in concussion knowledge; however, large improvements in concussion attitudes were observed between groups. These results suggest a continued improvement in student-athlete concussion awareness and provide specific areas to continue addressing persistent misconceptions.

Abstract
Purpose: Physical education (PE) teachers play an important role in concussion recognition and management in schools both in an academic and activity based setting. This study aimed to identify Irish post-primary PE teachers' concussion knowledge, beliefs, education and management practices. Methods: An anonymous online survey, adapted to the Irish context from the validated BAKPAC-TEACH, was completed by 128 PE teachers (female = 74/123; 60.2%; male = 49/123; 39.8%, 36.1 ± 10.9 years), representing 4% of registered PE teachers in Ireland. Results: PE teachers reported 3.5 ± 4.7 students suffer with a sports-related concussion in their classroom annually and 43.9% previously had a student sustain a concussion during their PE class. Most received concussion education (58.6%), largely provided by sporting bodies. They frequently identified dizziness (93.0%) and headaches (92.2%) as concussion symptoms, but less commonly emotional (more emotional = 36.5%, nervous or anxious = 33.6%, sadness = 28.9%) or sleep (35.2%) symptoms. All PE teachers knew that a concussion requires immediate removal from a game/practice. PE teachers demonstrated less perceived knowledge and confidence relating to academic adjustments and return to learn criteria. Just 31.3% reported their school facilitates academic adjustments. Conclusion: Tailored concussion education addressing knowledge gaps highlighted in this study should be developed. A concussion policy and an academic support team in each school should be established and widely publicised to enhance the support of concussed students in returning to school.

Abstract
Sport-related concussion incidence has increased in many team-based sports, such as rugby, Gaelic (camogie, hurling, football), and hockey. Concussion disrupts athletes' brain function, causing an "energy crisis" that requires energy and nutrient support to restore function and heal. Performance dietitians and nutritionists play a role in supporting athletes' post-injury nutritional demands. This study aimed to investigate Irish performance dietitians' and nutritionists' knowledge and implementation of nutritional strategies to manage and support athletes' recovery following concussion. In-depth, semi-structured interviews were conducted with seventeen (n = 17) Irish performance dietitians and nutritionists recruited from the Sport and Exercise Nutrition register and other sporting body networks across Ireland. Participants practised or had practised with amateur and/or professional athletes within the last ten years. All interviews and their transcripts were thematically analysed to extract relevant insights. These data provided valuable insights revealing performance dietitians and nutritionists: (1) their awareness of concussion events and (2) their use of nutritional supports for concussion management. Furthermore, the research highlighted their implementation of 'novel nutritional protocols' specifically designed to support and manage athletes' concussion recovery. There was a clear contrast between participants who had an awareness and knowledge of the importance of nutrition for brain recovery after sport-related concussion(s) and those who did not. Participants presenting with a practical understanding mentioned re-emphasising certain foods and supplements they were already recommending to athletes in the event of a concussion. Performance dietitians and nutritionists were keeping up to date with nutrition research on concussions, but limited evidence has prevented them from implementing protocols in practice. Meanwhile, participants mentioned trialling/recommending nutritional protocols, such as carbohydrate reloading, reducing omega-6 intake, and acutely supplementing creatine, omega-3 fish oils high in Docosahexaenoic acid, and probiotics to support brain healing. Performance dietitians' and nutritionists' use of nutrition protocols with athletes following concussion was linked to their knowledge and the limited scientific evidence available. Nutrition implementation, therefore, may be overlooked or implemented with uncertainty, which could negatively affect athletes' recovery following sports-related concussions.

Abstract
Background There are no studies investigating the level of knowledge about and attitude towards sports-related concussions (SRC) among sports coaches in Jordan. Objectives This study aimed to examine the knowledge about and attitude towards SRC among Jordanian sports coaches. Method Our study was based on a cross-sectional survey. An Arabic version of the questionnaire from the Centers for Disease Control and Prevention was used to collect data. The survey identified participants' demographics and knowledge about (0-10 points with higher scores indicating a higher knowledge) and attitude towards (8-40 with lower scores indicating favourable attitudes) SRC. Descriptive statistics and the Kruskal-Wallis test were used to examine knowledge and attitude differences by demographic factors. Spearman's correlation examined the correlation between the total knowledge and attitude scores. Results Participants included 193 coaches (62 basketball, 66 martial arts, 30 soccer, and 35 swimming). The median total knowledge and attitude scores were 4 and 30, respectively. The total knowledge score was the highest in martial arts coaches (median = 4) and those with graduate degrees (median = 5). The total attitude score was the lowest among basketball coaches (median = 28) and those who were 40-50 years old (median = 28). No significant correlation between knowledge and attitude scores was observed. Conclusion Jordanian coaches have a deficiency in knowledge about SRC and hold attitudes that are not consistent with current practice recommendations. Clinical implications Knowledge and attitude about SRC can be improved through education, access to healthcare providers, and adherence to SRC management guidelines.

Abstract
PRIMARY OBJECTIVE To gain an understanding of current evaluation practices, post-injury recommendations, and referrals to allied healthcare professions (AHP) by first-line healthcare professionals (FHPs) providing care for people with mild traumatic brain injury (mTBI). RESEARCH DESIGN Survey study. METHODS AND PROCEDURES Physicians, physician assistants, nurse practitioners, nurses, and athletic trainers (n = 126) completed an online survey, including Likert scale and free response question relating to mTBI evaluation, management, and referral practices. MAIN OUTCOMES AND RESULTS FHPs surveyed reported being confident in their ability to evaluate patients with suspected mTBI, relying most heavily on patient-reported symptoms and physical signs as methods of evaluation. Most FHPs reported making recommendations to compensate for the symptoms experienced following mTBI diagnosis. In contrast, FHPs expressed challenges in the evaluation and management of symptoms associated with mTBI along with limited knowledge of and referrals to AHPs. CONCLUSIONS Overall, FHPs feel confident in the diagnosis of mTBI but experience assessment and management challenges. AHPs are underutilized on mTBI management teams calling for a need for multidisciplinary collaboration on research, education, and rehabilitation efforts to optimally care for people experiencing mTBI symptoms.

Abstract
Participation in sport can incur a risk of sport-related concussion (SRC). Media representation of SRC is frequently at odds with up-to-date scientific data. Our findings confirm a significant amount of false, confusing, or misleading terminology used in reporting on the topic, which is concerning as media is as a major source of SRC information. Individuals have a variable base of knowledge pertaining to this injury, and accurate understanding of SRC does not always correlate to appropriate action. Inaccurate portrayal of SRC media may contribute to the confusion surrounding it. Popular media presents an opportunity to convey evidence-based information on SRC.

Abstract
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.

Abstract
Most of the research investigating sports concussion (SC) disclosure has been conducted using questionnaires with a pre-determined set of questions. Hence, significant gaps remain in our understanding of which factors weight in the decision-making process underlying SC disclosure and how they contribute to it. This present study aims to fill some of these gaps using qualitative methods to identify intrapersonal determinants of SC disclosure and describe their influence on an athlete's decision-making process. Our results are based on in-depth, semistructured interviews (range, 56-79 min; total = 587 min) with 9 university athletes (5 females, 4 males) from three team sports (soccer, rugby, and cheerleading). Using constant comparative analysis guided by Straussian grounded theory, we identified 13 concepts, across three major intrapersonal categories (i.e., attitudes and behaviors; concussion knowledge; and subjective evaluation of the concussion), contributing to SC disclosure, including novel determinants such as prioritization of athletic versus intellectual activities and maturity level. Our results suggest that a comparison between experiential knowledge and severity of the injury plays a major role in determining an athlete's disclosure behaviors. Athletes with a history of concussion seem to adopt a non-disclosure default strategy and are inclined to disclose their concussion symptoms only if they judge their current concussion to be worse than their previous most severe injury. Other concepts identified appear to contribute to the decisional process by modulating the adoption of this non-disclosure default strategy. Our work highlights the benefits and necessity of using qualitative methods to study the decision-making process underlying concussion disclosure.

Abstract
Authors of previous studies commonly used a multiselect checklist method to assess an athlete's ability to recognize true sport-related concussion (SRC) signs and symptoms (S&S) among incorrect distractor options. However, this may overinflate the evaluation of participants' knowledge because the multiselect method does not test athletes' ability to retrieve knowledge from their long-term memory. To examine this hypothesis, we sent an online survey to registered members of the Japan Lacrosse Association (n = 8530) to assess differences in reported SRC S&S by open-ended-question and multiselect formats. We also evaluated whether previous exposure to SRC education and a history of SRC influenced athletes' SRC S&S knowledge. The numbers and proportions of responses were calculated using descriptive statistics. The Pearson correlation was calculated to analyze the relationship between scores from the 2 question formats. Unpaired-samples t tests were conducted to compare the mean scores for each question format by previous SRC education and history of diagnosed SRC. Odds ratios were computed to express the relationship between the proportion of correct answers by question format per symptom. The response rate of the survey was 35.9% (n = 3065), and scores from the 2 question formats were correlated (r = 0.34, 95% CI = 0.31, 0.37; P < .001). For both question formats, athletes with previous exposure to SRC education and a history of SRC had a greater number of correct answers; however, the mean differences were trivial. Researchers and clinicians should acknowledge the difference between multiselect (recognition) and open-ended (free recall) formats when assessing one's understanding of SRC and managing athletes with a suspected SRC.

Abstract
While previous research has identified the reasons for the concussion-reporting behavior of rugby union players, the influence of confounding factors such as concussion experience, education, and knowledge of concussion symptoms, any of which may have influenced the results, has not been considered. This study aimed to clarify the reasons for the reporting behavior of college rugby union players regarding suspected concussion symptoms by adjusting for confounding factors using the propensity score. A questionnaire about both concussion knowledge and concussion-reporting behavior was administered to 240 collegiate rugby union players. Of the 208 (86.7%) valid respondents to the questionnaire, 196 (94.2%) had experienced any one symptom of a suspected concussion, such as headache, at least once, and 137 (65.9%) reported symptoms to someone else. This study's results revealed two important reasons for reporting symptoms: (1) the willingness of players to report experienced symptoms to someone else, along with realizing a concussion, and (2) the willingness of players to report suspected concussion symptoms, despite the absence of a doctor or trainer. These results suggest that providing educational opportunities to recognize suspected concussion symptoms and establishing a team culture of reporting physical problems to someone else is important for improving concussion-reporting behavior.

Abstract
Introduction Sport-related concussion (SRC) is a risk of collision sports such as women's rugby. To support appropriate SRC diagnosis and management, an understanding of the factors that encourage SRC disclosure is necessary. To date, research has focused on ascertaining individual player knowledge and attitudes towards SRC disclosure. Methods We chose to investigate the potential influence of group identification effects by examining the role of social identity on SRC disclosure in elite women's rugby. Seventeen elite players from the United Kingdom and Ireland were interviewed and their transcripts thematically analysed. Results The data highlighted that the players shared a very strong social identity as women in rugby and were acutely aware that their experiences were different to their male counterparts. The shared social identity had both positive and negative implications for SRC disclosure. The players interviewed did not feel comfortable disclosing their symptoms to their coach and often felt that medical staff either did not listen to them or were unavailable to them. Mediators such as communication, trust in medical teams, perceived pressure, positive injury management experience, and player role models were identified. Discussion This research could be utilised to inform sport psychology interventions to enhance SRC disclosure in elite women's rugby.

Abstract
Environmental temperature adversely affects the outcome of concussive head injury (CHI)-induced brain pathology. Studies from our laboratory showed that animals reared at either cold environment or at hot environment exacerbate brain pathology following CHI. Our previous experiments showed that nanowired delivery of oxiracetam significantly attenuated CHI-induced brain pathology and associated neurovascular changes. Military personnel are the most susceptible to CHI caused by explosion, blasts, missile or blunt head trauma leading to lifetime functional and cognitive impairments affecting the quality of life. Severe CHI leads to instant death and/or lifetime paralysis. Military personnel engaged in combat operations are often subjected to extreme high or low environmental temperature zones across the globe. Thus, further exploration of novel therapeutic agents at cold or hot ambient temperatures following CHI are the need of the hour. CHI is also a major risk factor for developing Alzheimer's disease by enhancing amyloid beta peptide deposits in the brain. In this review, effect of hot environment on CHI-induced brain pathology is discussed. In addition, whether nanodelivery of oxiracetam together with neprilysin and monoclonal antibodies (mAb) to amyloid beta peptide and p-tau could lead to superior neuroprotection in CHI is explored. Our results show that co-administration of oxiracetam with neprilysin and mAb to AβP and p-tau significantly induced superior neuroprotection following CHI in hot environment, not reported earlier.

Abstract
BACKGROUND Concussion nondisclosure and poor management after a concussion are a concern in Irish collegiate sports. How athletes perceive concussions and appraise their own concussion may affect their decisions and behaviors after a suspected concussion. However, this has yet to be examined in an Irish context. This study aimed to (1) establish concussion perceptions and associated anxiety in Irish collegiate athletes; (2) examine how sex, concussion, and mood disorder history influenced their perceptions; and (3) investigate factors associated with higher anxiety perceptions. HYPOTHESIS Irish collegiate athletes will display negative concussion perceptions and anxiety related to concussion, especially in female athletes and those without a concussion history. STUDY DESIGN Cross-sectional study. LEVEL OF EVIDENCE Level 3. METHODS Irish collegiate athletes [n = 268 (141 women,127 men), mean age = 21.5 ± 2.2 years] from high-risk sports completed a survey including the Perceptions of Concussion Inventory for Athletes (PCI-A), demographics, diagnosed concussion history, self-reported mood disorder history, and a concussion knowledge assessment. Differences in concussion perceptions by sex, concussion history, mood disorder history were examined using Mann-Whitney U tests, and factors associated with anxiety-related concussion perceptions were identified using multivariate logistic regression. RESULTS Over half (53.0%, n = 142) of participants reported concerns regarding concussion. The thoughts of sustaining a concussion made participants feel upset (63.4%, n = 170), fearful (47.7%, n = 128), and anxious (35.1%, n = 94). Women reported significantly higher anxiety (P < 0.01, r = 0.23), effects (P = 0.04, r = 0.12), and clarity (P = 0.01, r = 0.16) perception scores. Participants with a diagnosed concussion history displayed greater symptom variability perception scores (P = 0.04, r = 0.12), but lower anxiety (P = 0.03, r = 0.13) and treatment (P < 0.01, r = 0.19) beliefs on the PCI-A. No differences were observed for those with a history of a mood disorder (P > 0.05). A significant multivariate model was established (χ2 = 55.44, P < 0.01), with female sex [odds ratio (OR) = 1.53], concussion history (OR = 0.63), effects (OR = 1.31), and treatment (OR = 1.15) subscales associated with greater anxiety. CONCLUSION Concerns about sustaining a concussion are prevalent in Irish collegiate athletes. Women displayed more negative perceptions and those with a concussion history displayed fewer perceived benefits of treatment. CLINICAL RELEVANCE The findings support the need for concussion awareness campaigns to provide accurate concussion information to mitigate anxiety-related concussion perceptions and injury belief misconceptions.

Abstract
Objectives To determine sport-related concussion (SRC) incidence rates in female contact/collision sport. Design Systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Data sources Four databases (PubMed, SportsDiscus, Web of Science, CINAHL) were searched for data from 2012 to 2021. Eligibility criteria Studies reporting SRC incidence rates or the number of concussions and athletic exposures (AEs) per 1000 participating events or hours in healthy female contact and collision sport athletes of any age were included. Results The search yielded 8438 non-duplicate articles. Following screening, 19 were included in the analysis (median quality score=70%), with 8 reporting match or training incidence rates. Studies were primarily from US high school and collegiate populations; data are reported for eight sports. Rugby union reported the highest match SRC rates (8.2-16.11 per 1000 AE hours), followed by Gaelic football (5.21 per 1000 AE hours) and soccer (2.08-4.04 per 1000 AE events). Where available, match SRC rates were substantially higher than training and overall SRC rates. Conclusion Female sports such as rugby union, Gaelic football and soccer present the highest risk for SRCs within the available data. Previous research indicates a potentially greater injury burden for female athletes experiencing SRCs than their male counterparts. Thus, future research should analyse concussion knowledge and return-to-play protocols in these sports. Future research should also prioritise exploration of the gap in SRC rates within amateur sports, and data should be presented specifically in the context of athletic exposures (match vs training). Trial registration number CRD42021281569.

Abstract
Sports-related traumatic brain injuries are the most common injury in adolescents and young adults due to recurrent concussion experiences and head shock. Therefore, this study was designed to describe player characteristics and situational factors associated with concussions in the World Taekwondo Championships using systematic video analysis. Athlete injury data were collected using a web-based injury surveillance system at the World Taekwondo Championships organized by World Taekwondo from 2017 to 2019. Seven video footage were independently analyzed by four analysts using a modified Heads-Up Checklist. Descriptive statistical analysis was used. The incidence of concussion was 3.21 per 1000 games. Most players with concussions were shorter than their opponents, and most concussions were caused by a roundhouse kick on the front of the face. Regarding the acceleration direction of the head after the impact, transverse and multiplane directions were the most common. Most players with a concussion have used a closed stance and did not use blocking techniques during the defense. The rate of concussions caused by penalties was 42.9%. Based on our findings, no other injury mechanisms, except for direct blows to the head, were observed. Therefore, education on the risk and symptoms of concussion, the appropriate management and blocking techniques should be emphasized in TKD-S to reduce incidence of concussion.

Abstract
OBJECTIVES To examine the availability and content of publicly available concussion information published by peak amateur and professional combat sport governing bodies in Australia. DESIGN Cross-sectional study; document analysis. METHODS Publicly available concussion information was retrieved from the websites of eleven peak Australian amateur and professional combat sport governing bodies. Data on type of source material, concussion definition, provision of medical services, concussion evaluation, and return-to-sport information were extracted. The quality of the information was assessed using a modified version of the Global Rating Scale. RESULTS Eight out of eleven combat sport governing bodies provided concussion information in source documents ranging from competition rules to position statements to specific policies. Five governing bodies provided information on post-contest concussion evaluation or testing, four of which mentioned the Sport Concussion Assessment Tool. Eight governing bodies provided information on return-to-sport, of which six stipulated mandatory minimum rest periods and four indicated that athletes should complete a graduated return-to-sport protocol. The provided concussion information was generally of low quality, with a median score of 3 out of 9 (range: 1-4). CONCLUSIONS There is substantial scope and an urgent need for improving concussion guidelines across peak combat sport governing bodies in Australia to improve the health and safety of their athletes.

Abstract
Objective:Concussion is a common yet heterogenous injury. Approximately 15–30% of cases present with persistent post-concussion symptoms (PPCS), continuing 4 weeks or more post-injury in children, youth, and adolescents, and 3 months or more in adults. There are known bidirectional links between PPCS and mental health outcomes. The focus of this scoping review is to explore the literature on mental health outcomes in individuals experiencing PPCS. Research objectives were to explore: (1) the mental health outcomes of individuals with PPCS and types of assessments used to identify mental health outcomes this group, and (2) how mental health outcomes compare in terms of similarities and differences among pediatric and adult populations with PPCS.MethodOvid MEDLINE; EMBASE; CINAHL, and PsycInfo databases were searched. After title and abstract screening of 11,920 studies, 481 articles were reviewed. Twenty-five papers met inclusion criteria. Results were organized by mental health outcomes of pediatric and adult populations, separately.ResultsThere was a significantly higher number of studies devoted to adult populations. Of the 25 studies, 19 (76%) focused on adults, while six (24%) focused on adolescents. In adult populations, studies focused on symptoms of: anxiety (n = 2), depression (n = 8), and anxiety and depression (n = 9). Two studies assessed other emotional outcomes (10.5%). Within pediatric populations, an equal number of studies explored symptoms of: anxiety (n = 2), depression (n = 2), and anxiety and depression (n = 2). No studies focused on other emotional outcomes. Studies ranged greatly in methods, design, and control group. Most studies reported higher psychiatric symptoms of anxiety and/or depression in those with PPCS compared to individuals with recovered concussion or healthy controls.DiscussionThis review contributes to the understanding of mental health outcomes in those experiencing PPCS. Mental health and PPCS requires greater attention in pediatric populations, and consider strategies for those experiencing PPCS and mental health impacts. Future studies should consider including a wider range of emotional outcomes in their design, not limited to anxiety and depression. Study results may lead to improvements and research in the identification, assessment, and management of PPCS and mental health.

Abstract
Japan has no streamlined concussion education for collegiate athletes, and guidelines vary by sport. In particular, research on knowledge of, and attitudes toward, concussion is necessary for the establishment of concussion education for Japanese collegiate athletes. The aim of the present study was to assess the knowledge of, and attitudes toward, concussion in Japanese male collegiate athletes and to investigate their experiences with suspected concussion symptoms. An online questionnaire was administered to 390 collegiate athletes participating in the following five sports with a high incidence of concussion: rugby union, soccer, basketball, American football, and judo. Of the 121 valid responses, 91 (77.1%) indicated that they had experienced suspected concussion symptoms at least once and 46 of these 91 respondents had not reported their symptoms of suspected concussion at least once. Athletes who had never experienced concussion symptoms were significantly less likely to recognize the symptoms of concussion (p < 0.001). Most athletes recognized headache and dizziness as suspected concussion symptoms. However, the recognition rate for several symptoms was lower than the prevalence of these symptoms as shown in previous studies. This suggests that educational initiatives might be important to bridge the gap between athletes' knowledge and understanding of frequently occurring concussion symptoms and to improve reporting behavior.

Abstract
INTRODUCTION Military members' knowledge of concussion signs and symptoms may be critical to appropriate concussion identification and health-seeking behavior, particularly for those in leadership roles. The current study aimed to characterize concussion knowledge and attitudes among future military officers undergoing U.S.-based Reserve Officers' Training Corps (ROTC) training. MATERIALS AND METHODS Army and Air Force ROTC cadets at 2 large, public universities were utilized for a survey-based observational study. The study was approved by the institutional review board at both university research sites. Cadets completed a modified Rosenbaum Concussion Knowledge and Attitude Survey to obtain cadets' Concussion Knowledge Index and Concussion Attitude Index, where higher scores are preferable. Cadets' concussion knowledge and attitudes were characterized via descriptive statistics. RESULTS Cadets (n = 110) had a mean Concussion Knowledge Index of 18.8 ± 3.2 (range = 9-23, out of 25). Potentially detrimental misconceptions included: belief that typically concussion symptoms no longer persist after 10 days (79.1%) and brain imaging shows visible physical damage following concussion (74.5%). Mean Concussion Attitude Index was 60.6 ± 7.4 (range = 46-75, out of 75). In general, cadets reported higher agreement with safe concussion behavior than what they believe peers would report. CONCLUSIONS Cadets were found to have a high concussion knowledge, yet common misconceptions remained. Cadets consistently reported safe choices but were less sure that peers felt similarly; future investigations should evaluate ROTC concussion social norms and education should note peers' beliefs supporting safe concussion attitudes.
