AI Article Synopsis
- The study aimed to find out how preinjury and early postinjury psychological and injury factors can predict how long symptoms last after a sports concussion in high school and college athletes.
- Researchers evaluated 2,055 athletes before the season, and 127 of those who got concussions were assessed multiple times after their injury to analyze symptom duration using Cox proportional hazard modeling.
- Key findings revealed that preinjury somatic symptoms were the top predictor of how long symptoms lasted, while early postinjury symptom severity was equally important for recovery, suggesting that psychological factors can significantly impact recovery outcomes.
Article Abstract
Objective: To determine the degree to which preinjury and acute postinjury psychosocial and injury-related variables predict symptom duration following sport-related concussion.
Methods: A total of 2,055 high school and collegiate athletes completed preseason evaluations. Concussed athletes (n = 127) repeated assessments serially (<24 hours and days 8, 15, and 45) postinjury. Cox proportional hazard modeling was used to predict concussive symptom duration (in days). Predictors considered included demographic and history variables; baseline psychological, neurocognitive, and balance functioning; acute injury characteristics; and postinjury clinical measures.
Results: Preinjury somatic symptom score (Brief Symptom Inventory-18 somatization scale) was the strongest premorbid predictor of symptom duration. Acute (24-hour) postconcussive symptom burden (Sport Concussion Assessment Tool-3 symptom severity) was the best injury-related predictor of recovery. These 2 predictors were moderately correlated (r = 0.51). Path analyses indicated that the relationship between preinjury somatization symptoms and symptom recovery was mediated by postinjury concussive symptoms.
Conclusions: Preinjury somatization symptoms contribute to reported postconcussive symptom recovery via their influence on acute postconcussive symptoms. The findings highlight the relevance of premorbid psychological factors in postconcussive recovery, even in a healthy athlete sample relatively free of psychopathology or medical comorbidities. Future research should elucidate the neurobiopsychosocial mechanisms that explain the role of this individual difference variable in outcome following concussive injury.

Article Synopsis
- This study aimed to investigate the link between inflammatory biomarkers and recovery indicators in college athletes suffering from concussions.
- Conducted across multiple NCAA institutions, 422 participants were assessed with various clinical measures at different time points post-injury, focusing on multiple inflammatory markers in their blood.
- Results indicated that certain inflammatory markers, particularly IL-1RA and TNF, were associated with worse cognitive symptoms and recovery outcomes, especially in female athletes; however, similar associations were not found in nonathlete groups.

Objective: To identify risk factors and generate hypotheses for pediatric persistent postconcussion symptoms (PPCS).
Setting: A regional healthcare system in the Southeastern United States.
Participants: An electronic health record-based algorithm was developed and validated to identify PPCS cases and controls from an institutional database of more than 2.
Effect of Diagnosed Sleep Disorders on Baseline Concussion Symptom, Cognitive, and Balance Assessments in Collegiate Athletes.

Department of Orthopaedic Surgery, University of Pittsburgh, Pittsburgh, Pennsylvania, USA.
Background: Symptoms, cognition, balance, and other domains are commonly assessed at baseline testing as part of comprehensive preseason evaluations among collegiate student-athletes. Although approximately 27% of college students have at least 1 sleep disorder, researchers have yet to examine the role of a preexisting sleep disorder on preinjury baseline performance.
Purpose: To compare athletes with and without a reported history of diagnosed sleep disorders on commonly used baseline concussion assessments.

Objective: To characterize the psychological factors associated with persistent symptoms after pediatric concussion.
Study Design: Longitudinal cohort study of 179 children with concussion 8-18 years old evaluated in a pediatric emergency department. Participants were followed for 1 month for delayed symptom resolution, defined as ≥3 symptoms that were new/worse than preinjury symptoms measured by the use of graded symptom inventory.
