RESUMEN
OBJECTIVE: To examine whether a personal history of migraines is associated with worse acute symptom burden after sport-related concussion (SRC). DESIGN: Retrospective cohort study. SETTING: National Collegiate Athletic Association Division III collegiate programs. PARTICIPANTS: Collegiate athletes from a prospective concussion surveillance system between 09, 2014, and 01, 2023. INTERVENTION: Preinjury migraines (yes/no) were self-reported by athletes. MAIN OUTCOME MEASURES: Post-Concussion Symptom Scale (PCSS) were collected within 3 days postinjury. Mann-Whitney U tests compared total PCSS scores and individual symptom scores between athletes with and without preinjury migraines. Chi-squared tests were used to compare proportions of athletes endorsing individual symptoms (ie, item score ≥1) between 2 groups. Multivariable regression analyzed potential predictors of PCSS scores. RESULTS: Of 1190 athletes with SRC, 93 (7.8%) reported a preinjury history of migraines. No significant difference in total PCSS scores was found between athletes with and without preinjury migraines (22.0 ± 16.4 vs 20.5 ± 15.8, U = 48 719.0, P = 0.471). Athletes with preinjury migraines reported greater severity of "sensitivity to light" (1.59 ± 1.59 vs 1.23 ± 1.41, P = 0.040) and "feeling more emotional" (0.91 ± 1.27 vs 0.70 ± 1.30; P = 0.008) and were more likely to endorse "feeling more emotional" (45.2% vs 29.5%, P = 0.002). No differences were found across all other symptoms, including headaches (migraine = 87.1% vs no migraine = 86.3%, P = 0.835). In a multivariable model, a history of migraine was not a significant predictor of acute PCSS scores, but those with a history of psychological disorders (ß = 0.12, P <0 .001) and greater number of days to symptom evaluation (ß = 0.08, P = 0.005) had higher PCSS scores. CONCLUSIONS: Collegiate athletes with a pre-existing history of migraines did not have higher acute symptom burden after SRC.

Pre-injury migraines might be a risk factor for prolonged recovery after sport-related concussion (SRC). We sought to examine whether a pre-injury history of migraines is associated with worse recovery following SRC in collegiate athletes. Data were collected through a prospective concussion surveillance system in 11 National Collegiate Athletic Association (NCAA) Division III college athletic programs between September 2014 and March 2020. Our primary independent variable, pre-injury migraines, were self-reported by the athletes. Between those with and without migraines, the outcomes of days to return-to-learn (RTL) without academic accommodations and return-to-play (RTP) were compared using Mann-Whitney U tests. Each athlete's RTL and RTP status was dichotomized (i.e., returned vs. not returned) at various time points for RTL (i.e., 7/14/21/28 days) and RTP (i.e., 14/21/28/56 days). Chi-squared tests were performed to compare the proportions of RTL and RTP status between groups. Multivariable regressions analyzed potential predictors of RTL and RTP adjusting for age, gender, prior concussions, other health conditions, and symptom severity. Of 1409 athletes with an SRC, 111 (7.9%) had a pre-injury history of migraines. Compared with those without migraines, those with migraines had longer median (interquartile range [IQR]) days to RTL (migraines = 7.0 [3.0-12.3] vs. no migraines = 5.0 [2.0-10.0], U = 53,590.5, p = 0.022). No differences were found in RTP between the two groups (migraines = 16.0 [10.0-33.0] vs. nχo migraines 15.0 [11.0-23.0], U = 38,545.0, p = 0.408). Regarding RTL, significantly lower proportions of athletes in the migraine group had fully RTL, without accommodations, at ≤14 days (77.5% vs. 85.2%, χ2 = 4.33, p = 0.037), ≤21 days (85.3% vs. 93.0%, χ2 = 7.99, p = 0.005), and ≤28 days (88.2% vs. 95.6%, χ2 = 10.60, p = 0.001). Regarding RTP, a significantly lower proportion of athletes in the migraine group RTP at ≤28 days (72.0% vs. 82.7%, χ2 = 5.40, p = 0.020) and ≤56 days (84.0% vs. 93.0%, χ2 = 8.19, p = 0.004). In a multivariable model predicting RTL that was adjusted for age, gender, acute concussion symptoms, and other health variables (e.g., attention-deficit/hyperactivity disorder [ADHD], history of mental health difficulties), pre-injury history of migraine was associated with longer RTL (ß = 0.06, p = 0.030). In a multivariable model predicting RTP, pre-injury history of migraine was not associated with RTP (ß = 0.04, p = 0.192). In collegiate athletes, pre-injury migraine history was independently associated with longer RTL but not RTP. When comparing the proportions of those with successful RTP by days, significantly lower proportions of those with migraines showed successful RTP at ≤28 days and ≤56 days. Futures studies should study the generalizability of our findings in other school levels.

OBJECTIVE: To examine the association between insufficient sleep and baseline symptom reporting in healthy student athletes. DESIGN: Cross-sectional cohort study. SETTING: Preseason testing for student athletes. PARTICIPANTS: Student athletes (n = 19 529) aged 13 to 19 years who completed the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT), including the number of hours slept the night before, and denied having developmental/health conditions, a concussion in the past 6 months, and a previous history of 2 or more concussions. INDEPENDENT VARIABLES: Total hours of sleep the night before testing (grouped by ≤5, 5.5-6.5, 7-8.5, and ≥9 hours), gender, and concussion history. MAIN OUTCOME MEASURES: Symptom burden on the Post-Concussion Symptom Scale (modified to exclude sleep-related items), cognitive composite scores, and prevalence of athletes who reported a symptom burden resembling the International Classification of Diseases, 10th Revision (ICD-10) diagnosis of postconcussional syndrome (PCS). RESULTS: Fewer hours of sleep, gender (ie, girls), and 1 previous concussion (vs 0) were each significantly associated with higher total symptom scores in a multivariable model (F = 142.01, P < 0.001, R2 = 0.04). When a gender-by-sleep interaction term was included, the relationship between sleep and symptoms was stronger for girls compared with boys. In healthy athletes who slept ≤5 hours, 46% of girls and 31% of boys met the criteria for ICD-10 PCS compared with 16% of girls and 11% of boys who slept ≥9 hours. Sleep duration was not meaningfully associated with neurocognitive performance. CONCLUSIONS: Insufficient sleep the night before testing is an important factor to consider when interpreting symptom reporting, especially for girls. It will be helpful for clinicians to take this into account when interpreting both baseline and postinjury symptom reporting.

OBJECTIVE: To examine associations between pre-existing migraines and postconcussion symptoms and cognitive performance acutely (within 72 hours) after a suspected concussion. DESIGN: Nested case-control study. SETTING: High schools in Maine, USA. PARTICIPANTS: From a sample of 39 161 adolescent athletes who underwent baseline preseason testing, 633 were assessed within 3 days of a suspected concussion. Of these, 59 reported a history of treatment for migraines at baseline (9.3%). These athletes were individually matched to 2 athletes who had a suspected concussion but denied preinjury migraines (total N = 177; age: M = 15.8, SD = 1.3). ASSESSMENT OF RISK FACTORS: Self-reported history of treatment for migraines by a physician. MAIN OUTCOME MEASURES: Post-Concussion Symptom Scale total score, ImPACT composite scores, and individual symptom endorsement. RESULTS: Individuals with a pre-existing migraine disorder endorsed greater symptom severity (M = 8.4, SD = 9.9) compared with controls (M = 4.5, SD = 6.5; Cohen's d = 0.47) at preinjury baseline and acutely after suspected injury (migraine: M = 26.0, SD = 25.5; controls: M = 16.7, SD = 15.4; d = 0.44). Acutely after a suspected concussion, greater proportions of athletes with migraine disorders reported mental fogginess (49.2% vs 33.9%) and memory problems (39.0% vs 24.6%; P < 0.05). Baseline ImPACT composite scores were similar between migraine and control groups (d = 0.04-0.13). Adolescents with pre-existing migraine disorders performed worse after a suspected concussion compared with the control participants on verbal memory (F = 4.32, P = 0.041) and visual memory (F = 3.95, P = 0.049). CONCLUSIONS: Individuals with pre-existing migraine disorders may be at higher risk for worse outcomes, including greater overall burden of symptoms and worse cognitive functioning in the memory domain, in the first 72 hours after concussion.

CONTEXT: Student-athletes are commonly administered the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) battery at preseason baseline and postconcussion. The ImPACT is available in many languages, but few researchers have examined differences in cognitive performances and symptom ratings based on the language of administration. OBJECTIVE: To examine differences in ImPACT neurocognitive composites and symptom reporting at preseason baseline testing between student-athletes who completed ImPACT in Spanish versus English. DESIGN: Cross-sectional study. SETTING: Preseason baseline testing for a high school concussion-management program in Maine. PATIENTS OR OTHER PARTICIPANTS: Adolescent student-athletes who completed testing in Spanish (n = 169) and English (n = 169) were matched on age, gender, and health and academic history. Language groups were compared on each outcome for the full sample and for gender-stratified subsamples. MAIN OUTCOME MEASURE(S): Neurocognitive composite scores and individual and total symptom severity ratings from the ImPACT battery. RESULTS: Athletes tested in Spanish displayed lower levels of neurocognitive performance on 2 of 5 composite scores (visual motor speed: P < .001, d = 0.51; reaction time: P = .004, d = 0.33) and reported greater symptom severity (P < .001, r = 0.21). When the analyses were stratified by gender, similar visual motor speed differences were observed between language groups among boys (P = .001, d = 0.49) and girls (P = .001, d = 0.49), whereas reaction time showed a larger group difference for boys (P = .012, d = 0.42) than for girls (P = .128, d = 0.21). Language-group differences in symptom reporting were similar for boys (P = .003, r = 0.22) and girls (P = .008, r = 0.21), with more frequent endorsement of physical and affective symptoms by athletes tested in Spanish. CONCLUSIONS: Language-group differences in total symptom severity were small (r = 0.21) and in neurocognitive performances were small to medium (d = 0.05-0.51). Versus previous authors who compared athletes tested in Spanish and English with ImPACT, we observed smaller effects, which may be attributable to close matching on variables related to neurocognitive performances and symptom reporting.

OBJECTIVE: Identifying personal characteristics associated with sustaining a concussion is of great interest, yet only a few have examined this in children. The purpose of this study was to examine the association between sex, neurodevelopmental disorders, health history, and lifetime history of self-reported concussion in 12- and 13-year-old athletes. DESIGN: Cross-sectional study. SETTING: Middle schools. PARTICIPANTS: Participants were 1744 twelve- and thirteen-year-old student athletes who completed preseason Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) testing, including a self-report questionnaire about previous concussions, developmental diagnoses, and previous medical treatment. INDEPENDENT VARIABLES: Age, sex, attention-deficit/hyperactivity disorder (ADHD), learning disabilities (LDs), and previous treatment for migraine. MAIN OUTCOME MEASURES: Self-reported history of concussion. RESULTS: A minority of athletes (13.7%) reported previous concussions (1 concussion, n = 181; 2 concussions, n = 41; and 3+ concussions, n = 17). A small proportion reported a history of ADHD (4.4%), LD (2.8%) or migraine treatment (4.0%). Higher rates of self-reported previous concussions were associated with male sex [16.9% vs 9.1%; χ(1) = 21.47, P < 0.001] and previous migraine treatment [31.9% vs 13.0%; χ(1) = 20.08, P < 0.001]. There were no differences in self-reported concussion history between 12- and 13-year olds (P = 0.18) and those with/without ADHD (P = 0.41) or LDs (P = 0.06). The overall logistic regression model was statistically significant [χ(5) = 42.01, P < 0.001] but explained only 4.3% of the variance. Previous treatment for migraine [P < 0.001, Exp(B) = 3.30] and male sex [P < 0.001, Exp(B) = 2.06] were independently associated with a self-reported concussion history, whereas age, LD, and ADHD were not (P's > 0.05). CONCLUSIONS: Male sex and previous migraine treatment were associated with higher rates of self-reported previous concussions in both independent and multivariate models in middle school athletes, whereas age, ADHD, and LDs were not.

The objective of this study was to evaluate concussion-like symptom reporting among uninjured adolescents with Attention-deficit/hyperactivity disorder (ADHD), stratified by several cooccurring conditions, and to examine the base rate and predictors of uninjured adolescents with ADHD meeting diagnostic criteria for the International Classification of Diseases, 10th Revision (ICD-10) post-concussional syndrome (PCS). Participants in this cross-sectional, observational study, were drawn from a cohort of 48,834 adolescent student athletes from Maine (ages 13-18) with no concussion in the past 6 months who completed a preseason, baseline testing program between 2009 and 2015. The final sample included 3,031 students with ADHD, 2,146 (70.8%) boys and 885 (29.2%) girls. They were 15.2 years old on average (SD = 1.3). Concussion-like symptom reporting was more common in girls than boys. Most students with ADHD reported one or more symptoms (69.3% of boys and 81.1% of girls). The presence of an additional, co-occurring condition or comorbidity was associated with increased symptom reporting. In the absence of a recent concussion, 28.8% percent of boys and 47.1% of girls with ADHD endorsed symptoms resembling an ICD-10 diagnosis of post-concussional syndrome (PCS). Adolescents with pre-existing conditions were even more likely to endorse symptoms that resembled PCS (28-47% of boys and 45-69% of girls). Prior treatment for a psychiatric condition was the strongest independent predictor for meeting PCS criteria in boys, followed by treatment for migraines and co-occurring learning disorder. For girls, the only independent predictor was prior treatment of a psychiatric condition. In uninjured adolescent student athletes, ADHD appears to mimic the post-concussion syndrome. Adolescents with ADHD commonly endorse concussion-like symptoms in the absence of a recent concussion. Demographic characteristics (sex) and the presence of co-occurring conditions are related to symptom reporting in adolescents with ADHD. Understanding factors associated with baseline symptom reporting, such as pre-existing ADHD, is important when evaluating youth who have persistent symptoms following concussion as well as making both return to school and return to athletics decisions.
RESUMEN
Objective: Examine lifetime history of concussions in adolescents who have developmental problems in comparison with those with no developmental problems. Method: Thirty-two thousand four hundred eighty-seven adolescent athletes completed baseline/pre-season evaluations. Based on self-reported histories, athletes were divided into four groups: ADHD only, ADHD and learning difficulties (LD), LD only, and controls. Results: Athletes with ADHD, LD, or ADHD plus LD reported a greater prevalence of prior concussions than athletes without these developmental conditions (ps < .05). When adjusting for sex differences in concussion prevalence rates (boys are greater than girls), there was an increase in prevalence of prior injuries in those with ADHD, and ADHD plus learning difficulties compared with those with LD only. This pattern was found for both girls and boys. There was no additive effect of having both conditions. Conclusion: Developmental conditions in adolescent athletes, such as ADHD and learning difficulties, are associated with a greater prevalence rate of prior concussion.

Having a preexisting migraine disorder might be a risk factor for a prolonged recovery following a sport-related concussion. We examined whether having a migraine history was associated with a prolonged return to academics and athletics following a concussion. High school and collegiate athletes (n = 1265; 42% female) who sustained a sport-related concussion were monitored by athletic trainers using a web-based surveillance system that collects information about concussion recovery. Nonparametric Kolmogorov-Smirnov tests (KS) were used to compare days to return to academics/athletics across groups due to non-normally distributed outcome variables and unequal distributions of scores between groups. Chi-squared tests were used to examine the proportion of players who had not returned to academics/athletics at 7, 14, and 21 days post-injury stratified by self-reported migraine history. There were 117 athletes (9.2%) who reported a preinjury migraine history. Athletes with a history of migraine took a median of 6 days to return to academics (mean [M] = 10.6, standard deviation [SD] = 14.2) and 15.5 days to return to athletics (M = 23.8, SD = 30.8), while those with no migraine history took a median of 5 days to return to academics (M = 7.5, SD = 10.9) and 14 days to return to athletics (M = 19.4, SD = 19.4). There were no statistically significant differences in days to return to school or athletics between the groups (KS p > 0.05). However, a lower percentage of athletes with a history of migraine had returned to school after 7 days (57% vs. 68%, χ2 = 5.53, p = 0.02), 14 days (75% vs. 88%, χ2 = 14.21, p < 0.001), and 21 days post-injury (89% vs. 94%, χ2 = 4.90, p = 0.03). Stratifying the analyses by sex showed that this effect was significant in girls and women with preexisting migraines, but not boys and men with preexisting migraines. There were no group differences in recovery rates when examining return to athletics. Athletes with a preinjury migraine history may be at an elevated risk for a protracted return to school after concussion, especially girls and women.
RESUMEN
OBJECTIVE: ImPACT® (Immediate Post-Concussion Assessment and Cognitive Testing) is a computerized neuropsychological screening battery, which is widely used to measure the acute effects of sport-related concussion and to monitor recovery from injury. This study examined the factor structure of ImPACT® in several samples of high school student athletes. We hypothesized that a 2-factor structure would be present in all samples. METHOD: A sample of 4,809 adolescent student athletes was included, and subgroups with a history of treatment for headaches or a self-reported history of learning problems or attention-deficit hyperactivity disorder were analyzed separately. Exploratory principal axis factor analyses with Promax rotations were used. RESULTS: As hypothesized, both the combination of Verbal Memory and Visual Memory Composite scores loaded on one (Memory) factor, while Visual Motor Speed and Reaction Time loaded on a different (Speed) factor, in the total sample and in all subgroups. CONCLUSION: These results provide reasonably compelling evidence, across multiple samples, which ImPACT® measures 2 distinct factors: memory and speed.

IMPORTANCE: Every state in the United States has passed legislation for sport-related concussion, making this health issue important for physicians and other health care professionals. Safely returning athletes to sport after concussion relies on accurately determining when their symptoms resolve. OBJECTIVE: To evaluate baseline concussion-like symptom reporting in uninjured adolescent student athletes. DESIGN, SETTING, AND PARTICIPANTS: In this cross-sectional, observational study, we studied 31 958 high school athletes from Maine with no concussion in the past 6 months who completed a preseason baseline testing program between 2009 and 2013. RESULTS: Symptom reporting was more common in girls than boys. Most students with preexisting conditions reported one or more symptoms (60%-82% of boys and 73%-97% of girls). Nineteen percent of boys and 28% of girls reported having a symptom burden resembling an International Classification of Diseases, 10th Revision (ICD-10) diagnosis of postconcussional syndrome (PCS). Students with preexisting conditions were even more likely to endorse a symptom burden that resembled PCS (21%-47% for boys and 33%-72% for girls). Prior treatment of a psychiatric condition was the strongest independent predictor for symptom reporting in boys, followed by a history of migraines. For girls, the strongest independent predictors were prior treatment of a psychiatric condition or substance abuse and attention-deficit/hyperactivity disorder. The weakest independent predictor of symptoms for both sexes was history of prior concussions. CONCLUSIONS AND RELEVANCE: In the absence of a recent concussion, symptom reporting is related to sex and preexisting conditions. Consideration of sex and preexisting health conditions can help prevent misinterpretation of symptoms in student athletes who sustain a concussion.
