    Abstract: To examine baseline neurocognitive functioning and symptom reporting among adolescents with self-reported autism. Method Participants in this cross-sectional, observational study were 60,751 adolescents who completed preseason testing. There were 425 students (0.7%) who self-reported an autism spectrum disorder (ASD) diagnosis. Cognitive functioning was measured by Immediate Post-Concussion Assessment and Cognitive Testing and symptom ratings were obtained from the Post-Concussion Symptom Scale. Results Groups differed significantly across all neurocognitive composites (p values & lt;.002); effect size magnitudes for most differences were small, though among boys a noteworthy difference on visual memory and among girls differences on verbal memory and visual motor speed composites were noted. Among boys, the ASD group endorsed 21 of the 22 symptoms at a greater rate. Among girls, the ASD group endorsed 11 of the 22 symptoms at a greater rate. Some examples of symptoms that were endorsed at a higher rate among adolescents with self-reported autism were sensitivity to noise (girls: odds ratio, OR = 4.38; boys: OR = 4.99), numbness or tingling (girls: OR = 3.67; boys: OR = 3.25), difficulty remembering (girls: OR = 2.01; boys: OR = 2.49), difficulty concentrating (girls: OR = 1.82; boys: OR = 2.40), sensitivity to light (girls: OR = 1.82; boys: OR = 1.76), sadness (girls: OR = 1.72; boys: OR = 2.56), nervousness (girls: OR = 1.80; boys: OR = 2.27), and feeling more emotional (girls: OR = 1.79; boys: OR = 2.84). Conclusion Students with self-reported autism participating in organized sports likely experience a low degree of functional impairment, on average. If they sustain a concussion, their clinical management should be more intensive to maximize the likelihood of swift and favorable recovery.

    Multiple Past Concussions in High School Football Players : Are There Differences in Cognitive Functioning and Symptom Reporting?
    SAGE Publications ; 2016

    Abstract: There is increasing concern about the possible long-term effects of multiple concussions, particularly on the developing adolescent brain. Whether the effect of multiple concussions is detectable in high school football players has not been well studied, although the public health implications are great in this population. Purpose: To determine if there are measureable differences in cognitive functioning or symptom reporting in high school football players with a history of multiple concussions. Study Design: Cross-sectional study; Level of evidence, 3. Methods: Participants included 5232 male adolescent football players (mean [±SD] age, 15.5 ± 1.2 years) who completed baseline testing between 2009 and 2014. On the basis of injury history, athletes were grouped into 0 (n = 4183), 1 (n = 733), 2 (n = 216), 3 (n = 67), or ≥4 (n = 33) prior concussions. Cognitive functioning was measured by the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) battery, and symptom ratings were obtained from the Post-Concussion Symptom Scale. Results: There were no statistically significant differences between groups (based on the number of reported concussions) regarding cognitive functioning. Athletes with ≥3 prior concussions reported more symptoms than did athletes with 0 or 1 prior injury. In multivariate analyses, concussion history was independently related to symptom reporting but less so than developmental problems (eg, attention or learning problems) or other health problems (eg, past treatment for psychiatric problems, headaches, or migraines). Conclusion: In the largest study to date, high school football players with multiple past concussions performed the same on cognitive testing as those with no prior concussions. Concussion history was one of several factors that were independently related to symptom reporting.

    Investigating Effects of Sex Differences and Prior Concussions on Symptom Reporting and Cognition Among Adolescent Soccer Players
    SAGE Publications ; 2018

    Abstract: There has been increasing concern regarding the possible effect of multiple concussions on the developing brain, especially for adolescent females. Hypothesis/Purpose: The objectives were to determine if there are differences in cognitive functioning, symptom reporting, and/or sex effects from prior concussions. In a very large sample of youth soccer players, it was hypothesized that (1) there would be no differences in cognitive test performance between those with and without prior concussions, (2) baseline preseason symptoms would be better predicted by noninjury factors than concussion history, and (3) males and females with prior concussions would not have differences in cognition or symptoms. Study Design: Cross-sectional study; Level of evidence, 3. Methods: Participants included 9314 youth soccer players (mean = 14.8 years, SD = 1.2) who completed preseason baseline cognitive testing, symptom reporting, and a health/injury history questionnaire from the ImPACT battery (Immediate Post-concussion Assessment and Cognitive Testing). On the basis of injury history, athletes were grouped by number of prior concussions: 0 (boys, n = 4012; girls, n = 3963), 1 (boys, n = 527; girls, n = 457), 2 (boys, n = 130; girls, n = 97), or ≥3 (boys, n = 73; girls, n = 55). The primary measures were the 4 primary cognitive scores and the total symptom ratings from ImPACT. Primary outcomes were assessed across injury groups, controlling for age, sex, learning disability, attention-deficit/hyperactivity disorder (ADHD), treatment for headaches/migraines, substance abuse, and mental health problems. Results: Cognitive test performance was not associated with concussion history but was associated with sex, age, learning disability, ADHD, and prior mental health problems. Greater symptom reporting was more strongly associated with psychiatric problems, older age, learning disability, substance abuse, headaches, being female, and ADHD than with a history of multiple concussions. Boys and girls did not differ on cognitive scores or symptom reporting based on a history of concussion. Conclusion: In this very large sample of youth soccer players with prior concussion, there was no evidence of negative effects on cognition, very weak evidence of negative effects on symptom reporting, and no evidence of sex × concussion differences in cognition or symptom reporting.

    Abstract: To investigate (1) if there are meaningful differences in baseline preseason cognitive functioning or symptom reporting between high school ice hockey players with and without prior concussions and (2) determine which health history variables predict symptom reporting. Design: Cross-sectional study. Setting: High schools across the state of Maine. Participants: Participants were 1616 male high school ice hockey players (mean age = 15.6 years; SD = 1.5 years) who completed baseline testing between 2009 and 2015. Independent Variables: Athletes were grouped according to their self-reported concussion history [0 (n = 1136), 1 (n = 321), 2 (n = 112), or 3+ (n = 47) previous concussions]. Main Outcome Measures: Cognitive functioning was measured by the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) battery, and symptom ratings were obtained from the Post-Concussion Symptom Scale. Results: There were no statistically significant differences between groups in cognitive functioning as measured by ImPACT. The group with ≥3 prior concussions endorsed higher total symptom scores, but the effect sizes were small and not statistically significant. In a multivariate model, prior treatment for headaches (not necessarily migraines), prior treatment for a psychiatric condition, and prior treatment for substance/alcohol use all significantly predicted total symptom scores, with concussion history being the weakest independent predictor. Conclusions: Players with a history of prior concussions performed similarly to players with no prior concussions on cognitive testing. Health history factors were more strongly associated with symptom reporting than concussion history.

    In: Journal of Child Neurology, SAGE Publications, Vol. 37, No. 12-14 ( 2022-12), p. 970-978
    Abstract: We examined the association between the severity of acute concussion symptoms and time to return to school and to sports in adolescent student athletes. We hypothesized that there would be an association between the severity of acute symptoms experienced in the first 72 hours and functional recovery such that adolescents with the lowest burden of acute symptoms would have the fastest return to school and sports and those with the highest burden of symptoms would have the slowest return to school and sports. This injury surveillance cohort included 375 adolescent student athletes aged 14-19 years who sustained a sport-related concussion between 2014 and 2020. Athletic trainers documented time to return to school and to sports. A greater proportion of adolescents with the highest acute symptoms remained out of school at 3 (odds ratio [OR] = 2.5, 95% confidence interval [CI] 1.5-4.4), 5 (OR = 2.4, 95% CI 1.4-4.0), 7 (OR = 2.6, 95% CI 1.5-4.3), and 10 days (OR = 2.3, 95% CI 1.3-3.9) compared to those with the lowest acute symptoms. Similarly, a greater proportion of athletes with the highest acute symptoms remained out of sports at 7 (OR = 3.5, 95% CI 1.5-8.1), 10 (OR = 3.1, 95% CI 1.8-5.6), 14 (OR = 1.8, 95% CI 1.1-3.0), and 21 days (OR = 1.9, 95% CI 1.0-3.6) compared to those with the lowest acute symptoms. This study underscores the adverse effect of high acute symptom burden following concussion on return to school and to sports among adolescent student athletes. Conversely, student athletes with a low burden of acute symptoms have a faster return to school and to sports.

    Abstract: This study examined the association between past concussions and current preseason symptom reporting and cognitive performance in 9,257 youth ages 11–13. Participants completed neurocognitive testing prior to participating in a school sports between 2009 and 2019. We stratified the sample by gender and number of prior concussions and assessed group differences on the Post-Concussion Symptom Scale total score and the ImPACT cognitive composite scores. Those with≥2 prior concussions reported more symptoms than those with 0 concussions (d=0.43–0.46). Multiple regressions examining the contribution of concussion history and developmental/health history to symptom reporting showed the most significant predictors of symptoms scores were (in descending order): treatment for a psychiatric condition, treatment for headaches, history of learning disability (in boys only), history of attention-deficit/hyperactivity disorder, and age. Concussion history was the weakest statistically significant predictor in boys and not significant in girls. Cognitively, boys with 1 prior concussion had worse speed those with 0 concussions (d=0.11), and girls with≥2 prior concussions had worse verbal/visual memory than girls with 0 concussions (ds=0.38–0.39). In summary, youth with≥2 prior concussions reported more symptoms than those with no concussions. Boys with multiple concussions performed similarly on cognitive testing, while girls had worse memory scores.

    Network Structure of Physical, Cognitive, and Emotional Symptoms at Preseason Baseline in Student Athletes with Attention-Deficit/ Hyperactivity Disorder
    Oxford University Press (OUP) ; 2020

    Abstract: Preexisting attention-deficit/hyperactivity disorder (ADHD) may be a risk factor for worse outcome following sport-related concussion. We used a statistical and psychometric approach known as network analysis to examine the architecture of physical, cognitive, and emotional symptoms at preseason baseline among student athletes with ADHD. Method A cohort of 44,527 adolescent student athletes completed baseline preseason testing with ImPACT® between 2009 and 2015. A subsample of athletes reporting a diagnosis of ADHD and at least one symptom were included in this study (N = 3,074; 14–18 years old, 32.7% girls). All participants completed the 22-item Post-Concussion Symptom Scale at preseason baseline. Results Student athletes reported high frequencies of difficulty concentrating (boys/girls = 50.7%/59.4%), emotional symptoms (nervousness: boys/girls = 30.2%/51.0%; irritability: boys/girls = 23.6%/34.8%; sadness: boys/girls = 21.4%/39.7%), sleep/arousal-related symptoms (trouble falling asleep: boys/girls = 39.5%/49.4%; sleeping less than usual: boys/girls = 36.2%/43.4%; and fatigue: boys/girls = 29.8%/36.4%), and headaches (boys/girls = 27.6%/39.0%) during preseason baseline testing. The most central symptoms included dizziness, which was related to multiple somatic symptoms, and increased emotionality, which was related to a cluster of emotional symptoms. Girls reported symptoms at a greater frequency than boys, and there was evidence for variance in the global strength of the symptom network across gender, but not specific intersymptom relationships. Conclusion In the absence of injury, symptoms that commonly occur after concussion interact and potentially reinforce each other among student athletes with ADHD at preseason. Symptoms common in ADHD (i.e., difficulty concentrating) are not necessarily the most central within the symptom network. These findings may inform more precise interventions for athletes with ADHD and prolonged recovery following concussion.
