Abstract	Objective: To examine baseline neurocognitive functioning among adolescent athletes on the autism spectrum based on self-reported level of academic performance. Method: Participants in this cross-sectional, observational study were 6,441 adolescent athletes with a self-reported diagnosis of autism who completed pre-season neurocognitive testing using Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT); 4,742 reported a co-occurring learning disorder (LD), and 6,612 individuals without autism or LD were included as a control group. The majority (57%) self-reported Average Academic Performance, 39% Above Average, and 4% Below Average performance. Results: Athletes with self-reported autism (with or without LD; 12.2%) were 2.74x (95% CI: 2.17-2.82) more likely to fall below cutoffs for ImPACT Embedded Invalidity Indicators (EVIs), with a significant interaction between self-reported Diagnosis and Academic Performance; individuals with co-occurring autism and LD who reported Below Average Academic Performance had the greatest likelihood of scoring below cutoffs (22%), followed by ASD without LD (14.8%) and Controls (14.6%) with Below Average Academic Performance. Analyses of variance (ANOVAs) revealed main effects of Diagnosis and Academic Performance on neurocognitive performance, with interactions on all ImPACT Composite Scores except Processing Speed. Conclusion: Athletes with self-reported ASD are more likely to fall below ImPACT EVIs and score worse on ImPACT, with greater likelihood/worse performance related to level of academic functioning. Academic performance should be considered when interpreting neurocognitive testing data, to best index neuropsychological functioning associated with concussion in this population. The current findings highlight the importance of individual participant baseline neuropsychological testing for individuals on the autism spectrum.

Article ; Online: Progesterone Levels in Adolescent Female Athletes May Contribute to Decreased Cognitive Performance During Acute Phase of Sports-Related Concussion.

Ott, Summer / Redell, John / Cheema, Sukhnandan / Schatz, Philip / Becker, Elizabeth

Abstract	Although many outcome studies pertaining to sports-related concussion exist, female athletes with concussion remain an understudied group. We examined whether neurocognitive performance in adolescent females with sports-related concussion (SRC) is related to menstrual cycle-related hormone levels measured at one-week post-concussion, one-month post-concussion, or both. Thirty-eight female athletes, ages 14-18, were matched into two groups: SRC or healthy control. Self-reported symptom scores were higher among concussed females in the luteal phase, when progesterone levels are highest. Results suggest that progesterone levels may contribute to a heightened experience of symptoms during the acute phase of SRC, providing further evidence of a possible link between progesterone and symptom scores following concussion.

Abstract	Objective: To identify criteria used by sports neuropsychologists in determining recovery following sport-related concussion. Methods: Forty-six sports neuropsychologists completed a custom survey, rating the importance of specific criteria for determining concussion recovery in youth versus adults. Percentages and modal ratings were documented. Results: "Back to work/school without accommodations," "No headache after neurocognitive testing," "Feeling 100% back to normal," and "No symptoms after noncontact exertion" were rated highest for youth and adults. "Physician examination without concerns" and "Balance testing" were the two lowest rated items for both youth and adults. For youth, "sufficient" amount of time symptom-free needed for recovery was seen as longer than for adults. Conclusions: There was some similarity in how sports neuropsychologists determine concussion recovery for both adults and youth. Future studies should include a larger sample size and concussion experts from other specialties to identify the current multidisciplinary standard of care.

Abstract	Forty parents of youth soccer players of ages 5-17 years, in Sicily, Italy completed a survey measuring knowledge of concussion symptoms and facts. Parents averaged 16 out of 23 correct responses (69.5%) on the survey, with no significant correlation between parental age and education and knowledge. Italian parents were more familiar with somatic symptoms (92.5%-100% correct) than emotional/behavioral (27.5%-57.5% correct) and sleep symptoms (45.0%). Comparisons to U.S. and Australian research showed general agreement on knowledge of concussion symptoms, but less awareness of other concussion facts among Italian parents. More research on cross-cultural concussion education and barriers to concussion resources is warranted.

Abstract	Context: The Concussion Clinical Profile Screening Tool (CP Screen) self-report concussion symptom inventory that is often administered at weekly intervals. However, 1-week reliable change indices (RCI) for clinical cutoffs and the test-retest reliability of the CP Screen is unknown. Objective: Document RCI cutoff scores and 1-week test-retest reliability for each profile and modifier of the CP Screen for males and females. Design: Case Series. Setting: A large US university. Patients or other participants: 173 healthy college students. Main outcome measure(s): Participants completed two administrations of the CP Screen 7 days apart; CP Screen items yield five clinical profiles and two modifiers. Spearman rho coefficients (rs), intraclass correlation coefficients (ICCs) single measures and Unbiased Estimates of Reliability (UER) were used to assess test-retest reliability. Wilcoxon signed-rank tests assessed differences across time. RCI values and cutoff scores are provided at 90%/95% confidence intervals (CI). All analyses were performed for the total sample and separately for males and females. Results: RCI cutoffs for clinically significant change (increase/decrease) at a 90% CI for males were as follows: Ocular, Vestibular >2/>4, Anxiety/Mood, Cognitive/Fatigue, Migraine>3/>3, Sleep >4/>6, and Neck>2/>2. RCI cutoffs for clinically significant change (increase/decrease) at a 90% CI for females were as follows: Anxiety/Mood≥2/≥4; Cognitive/Fatigue, Migraine, Ocular, Vestibular, Sleep≥3/≥3; and Neck≥1/≥1. Correlations for CP ranged from .51 (Migraine) to .79 (Anxiety/Mood) for the total sample, .48 (Migraine) to .84 (Vestibular) for males, and .51 (Migraine) to .77 (Ocular) for females. Test-retest indices for each profile and modifier were moderate to good for the total sample (ICC: .64-.82; UER: .79-.90), males (ICC: .60-.87; UER: .76-.94), and females (ICC: .64-.80; UER: .78-.89). Conclusion: The CP Screen is reliable and stable across a 1-week interval, and established RCIs for males and females can help identify meaningful change throughout recovery.

Abstract	ImPACT® Pediatric is an examiner-administered iOS-based battery of neuropsychological tests designed to measure neurocognitive functioning in children ages 5-11. This study documented Multivariate Base Rates (prevalence of low scores when multiple test scores are considered simultaneously) in the ImPACT® Pediatric standardization sample (N = 892). In the total sample, it was common for children to obtain at least one low factor score using the 25th percentile [T 43; base rate (BR) = 54.2%], 16th percentile (T40, BR = 38.1%), and the 10th percentile (T37, BR = 31.1%). However, it was uncommon for children to obtain two (or more) low factor scores using any of the above-listed cutoff score.

Abstract	This study documented the rate of Performance Validity Testing (PVT) failure in 81 youth athletes, aged 10-21 years, experiencing prolonged recovery following sports-related concussion, and the relationship between PVT and emotional symptoms. Neuropsychological assessments were conducted across three test sessions with a stand-alone PVT at each session. Results showed that 48% (39/81) of individuals failed at least one PVT, with an overall PVT failure rate of 26% (64/243). Those failing at least one PVT scored significantly higher on anxiety but not depression or somatization. Results illustrate the importance of including measures of emotional and behavioral functioning in testing following SRC.

Abstract	Youth league administrators (N = 172) documented knowledge of/compliance with state concussion legislation, and were assigned to groups based on whether their state concussion legislation extended to non-school-affiliated (NSA) youth sport leagues: EXTEND (50.6%) or NOT EXTEND (49.4%). Administrators within the EXTEND group were 2.7x more likely to report having a formal concussion policy. Only 90.7% confirmed a policy for removing concussed athletes from play, and 75% required independent medical clearance, and 82% mandated education for coaches, 49.1% for parents, and 35.9% for athletes. These results raise questions regarding compliance with state concussion legislation, especially for NSA youth sports leagues.
