Participants completed neurocognitive testing prior to\n                    participating in a school sports between 2009 and 2019. We stratified the sample\n                    by gender and number of prior concussions and assessed group differences on the\n                    Post-Concussion Symptom Scale total score and the ImPACT cognitive composite\n                    scores. Those with\u22652 prior concussions reported more symptoms than those\n                    with 0 concussions (d=0.43\u20130.46). Multiple regressions examining\n                    the contribution of concussion history and developmental\/health history\n                    to symptom reporting showed the most significant predictors of symptoms scores\n                    were (in descending order): treatment for a psychiatric condition, treatment for\n                    headaches, history of learning disability (in boys only), history of\n                    attention-deficit\/hyperactivity disorder, and age. Concussion history\n                    was the weakest statistically significant predictor in boys and not significant\n                    in girls. Cognitively, boys with 1 prior concussion had worse speed those with 0\n                    concussions (d=0.11), and girls with\u22652 prior concussions had\n                    worse verbal\/visual memory than girls with 0 concussions\n                    (ds=0.38\u20130.39). In summary, youth with\u22652 prior\n                    concussions reported more symptoms than those with no concussions. Boys with\n                    multiple concussions performed similarly on cognitive testing, while girls had\n                    worse memory scores.<\/jats:p>","DOI":"10.1055\/a-1538-0075","type":"journal-article","created":{"date-parts":[[2022,1,14]],"date-time":"2022-01-14T23:33:32Z","timestamp":1642203212000},"page":"553-560","source":"Crossref","is-referenced-by-count":2,"title":["Preseason
