Summary: ImPACT is commonly used for clinical management of sport concussion. However, factor analysis suggests that the current cognitive composites may not adequately represent the cognitive constructs assessed. Exploring the latent structure of ImPACT cognitive baseline scores, the study identified a four-factor model which provided superior fit compared to the current five-composite structure.

Summary: This is a systematic review and meta-analysis that aims to define the time frames, measures used, and modifying factors influencing recovery, return to school/learn, and return to sport after sport-related concussion. The study included 278 studies and found that most athletes have a full return to school by 10 days but take twice as long for a return to sport. The impact of gender and age on recovery time is uncertain.

Summary: Female athletes are more susceptible to sport-related concussions, especially in soccer. They experience more somatic symptoms such as headache, migraine, and sleep disturbance, and may require longer recovery time. The 6th ICSS does not extensively address sex differences, which are crucial for concussion management protocols in many sports.

Summary: Research in Michigan high school sports found that female athletes were more likely than male athletes to not be immediately removed from activity after sustaining a sports-related concussion, especially in sports like soccer, basketball, baseball/softball, and lacrosse.

Summary: Research shows that female athletes are more likely to report sports-related concussions than male athletes, but they are also more likely to continue playing without being removed from activity.

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: Injury and concussion rates are high in female high school rugby players, with tackling being the most common mechanism. Prevention strategies should be explored to improve sport safety.

Summary: This review systematically examines factors to consider when advising athletes about retirement after sport-related concussion (SRC) and defines contraindications for children/adolescents participating in contact or collision sports following SRC. The study found no evidence to support absolute indications for retirement or discontinuation from contact or collision sport based on patient-specific, injury-specific or other factors (such as imaging findings).

Summary: A study on the acute and early long-term associations of sport-related concussion (SRC) and subcortical and cortical structures in collegiate contact sport athletes showed that a single SRC had minimal associations with grey matter structure across a 6-month time frame.

Summary: The research found that young men who played high school football are not at an increased risk for suicide ideation between the ages of 24 and 32 compared to those who did not play football. Individuals who underwent psychological counseling during adolescence were more likely to report depression and suicide ideation in adulthood.

Summary: The study aims to quantify and assess Head Impact Exposure (HIE) metrics among youth and collegiate football players. The study found that youth players experienced fewer impacts and lower impact magnitudes compared to collegiate players, with impacts during competition being more frequent and of greater magnitude than during practice at both levels.

Summary: Recent research indicates a link between soccer heading and neurodegenerative disease in retired players. To address this, restrictions have been implemented to limit heading in training and matches. This study investigated the effectiveness of training soccer heading in immersive VR and found that the VR group showed improvements in goal scoring, confidence, and self-efficacy. These results support the inclusion of VR-based training for heading skills without exposure to repeated head impacts.

Summary: This study investigated the association between playing high school football and the risk of depression and suicidality in middle-aged men. The results showed that individuals who played football during adolescence did not have an increased risk of depression or suicidal ideation in their middle 30s to early 40s. However, mental health problems during adolescence were associated with an increased risk for psychological difficulties more than 20 years later.

Summary: This study found that over half of middle-aged men met the symptom criteria for traumatic encephalopathy syndrome (TES), with neurotrauma exposure not being a significant predictor of meeting the criteria. Sleep difficulties and chronic pain were predictive of meeting the symptom criteria for TES.

Summary: The Concussion in Sport Group has been holding meetings and developing statements on concussion in sport for over 20 years. This 6th statement provides a summary of the outcomes of the 6th International Conference on Concussion in Sport held in Amsterdam in October 2022. It includes revised assessment tools and integrates new features such as a focus on para athletes and the athlete's perspective, as well as addressing ethical issues and long-term effects of sport-related concussion.
