Summary: This study aimed to examine SCAT5 baseline and acute symptom subscales in professional hockey players. The results showed that concussed players reported more acute symptoms than active controls on each of the subscales, and cognitive difficulties, somatic/physical difficulties, and headache were most associated with concussion diagnosis at the acute evaluation. An abbreviated acute symptom scale may be useful for diagnostic purposes when evaluation time is limited. Approximately 2% of players reported significantly elevated affective/emotional symptoms at baseline, which was associated with an increased likelihood of concussion diagnosis.

Summary: This study aimed to investigate whether male collision sport athletes performed worse on computerised neurocognitive assessments and reported higher symptom burdens compared to athletes in contact (but not collision) sports and athletes in non-contact sports. The results showed minimal differences in performance on neurocognitive assessments between collision sport, contact sport, and non-contact sport athletes. Additionally, collision and contact sport athletes had slightly lower total symptom scores than non-contact sport athletes.

Summary: Mild traumatic brain injury (mTBI) has a high incidence worldwide, and long-term persistent postconcussion symptoms (PPCS) are predicted by psychological and psychiatric factors. Anxiety, depressive symptoms, and emotional distress early after injury can predict PPCS burden and functional outcome. Coping styles, preinjury psychiatric disorders and mental health also correlate with PPCS burden and functional outcome.

Summary: Biopsychosocial models are used to explain PPCS after concussion, highlighting the role of psychological factors. However, clinicians face challenges in addressing these factors. This article provides guidance on understanding and applying psychological factors in the clinical management of PPCS.

Summary: This systematic literature review aimed to determine the accurate tests and measures for diagnosing persisting post-concussive symptoms (PPCS) in children, adolescents, and adults following sport-related concussion (SRC). The results showed that the diagnosis of PPCS still relies on symptom report, preferably using standardized symptom rating scales. No specific tool or measure has been found to have satisfactory accuracy for clinical diagnosis.

Summary: Concussion is a growing public health concern. Infralow frequency neuromodulation (ILF) has been found to be effective in treating postconcussion symptoms (PCS) and persistent postconcussion symptoms (PPCS).

Summary: Sleep behavior and physical activity in the first month after adolescent sports-related concussion are associated with the development of persisting postconcussion symptoms (PPCS). More exercise sessions that were longer than 15 minutes during concussion recovery were associated with a lower risk of developing PPCS, while sleep and other physical activity measures were not significant predictors.

Summary: This study aimed to explore the heterogeneity of persisting symptoms after sport-related concussion (SRC) and found evidence for the existence of symptom subtypes and subgroups of patients with a comparable configuration of co-occurring symptom subtypes. These subgroups differed in pre-injury, personality, and SRC characteristics, suggesting that these factors may contribute to the emergence of specific SRC patient subgroups. The subgroups also differed in the severity of persisting symptoms, highlighting the clinical relevance of SRC subgrouping and the need for targeted prognosis, clinical management, and treatment to optimize recovery.

Summary: This study aims to develop an MMPI-2-RF reference group for persistently symptomatic patients with mTBI to aid interpretation and better evaluate atypical scale elevations. By comparing MMPI profiles of patients with mTBI against this reference group, clinicians may be better able to identify abnormal symptomatology and provide more accurate case conceptualization and targeted treatment recommendations.

Summary: This study investigated whether there are differences in concussion-associated polygenic profiles between elite rugby athletes and non-athletes, as well as between rugby union forwards and backs. The results suggest that elite rugby athletes do not have a more "preferable" concussion-associated polygenic profile than non-athletes, but there may be a genetic interaction between COMT (rs4680) and MAPT (rs10445337) that assists rugby athletes in achieving elite status.

Summary: Poor sleep is common among collegiate student-athletes and may increase the risk of sport-related concussions (SRC) in the long term. Factors such as symptom reporting and neurocognitive performance at baseline are also associated with insufficient sleep. This study examines the implications of baseline insufficient sleep and its association with SRC risk.

Summary: A sports-related concussion (SRC) often leads to shearing and stretching of axons in the white matter, causing secondary inflammatory processes and persistent post-concussive symptoms (PPCS). In this study, athletes with PPCS showed signs of ongoing neuroinflammation, as indicated by altered profiles of cerebrospinal fluid (CSF) biomarkers. The findings suggest the importance of studying treatments targeting the post-injury inflammatory response in sports-related concussion.

Summary: This study investigated the prevalence of anxiety and depression symptoms in PCS patients, finding a considerable proportion of patients experiencing these symptoms. Additionally, the number of previous concussions was correlated with anxiety and depression symptoms, and patients with more severe symptoms exhibited lower quality of life.

Summary: This prospective cohort study followed 2160 high school athletes over 2 years and found that sport-related concussion did not significantly worsen depression in adolescent athletes, and that depression symptoms improved after concussion symptom resolution. Female athletes reported more severe symptoms in the first few days after concussion compared to male athletes.
