Objective The primary objective of this review paper is to introduce the underlying neurobiology of concussion symptoms, including relevant neuroanatomy, and to discuss these findings relative to the traditional homogenous model and a newer clinical profile model for sport-related concussion (SRC) assessment, conceptualization, and treatment. Method Empirical studies, meta-analyses, and consensus statements relevant to the assessment, conceptualization, and treatment of SRC were identified via systematic, but informal, procedures. This literature review focused on papers discussing the neuroanatomy and neurobiology of concussion symptoms and sequelae, as well as the exploration of new clinical treatment models for SRC. Results Exploration of the literature further supports the use of a clinical profiles-based SRC assessment and treatment protocol. Comparisons of traditional and new protocols show that a traditional assessment, conceptualization, and treatment model of SRC as a homogenous injury inadequately captures the individual injury experience and recovery trajectory. Conclusions This review confirms existing literature that the clinical profiles-based model best addresses the heterogeneous nature of sport-related concussion using a neurobiological and neuroanatomical approach to understanding SRC. Utilizing this model, clinicians can provide an individualized assessment, conceptualization, and treatment plan for SRC, leading to an improved clinical experience for athletes and better clinical outcomes.

Prevalence of mental health (MH) concerns among young adults is high and continues to increase. As a specific subset of young adults, National Collegiate Athletic Association (NCAA) athletes seem to experience these concerns at a similar or greater prevalence rate than their nonathlete, age-matched peers. Yet, how MH affects sport performance has not been robustly studied, and existing studies have not included the diversity of identities present in the collegiate athlete population. Thus, via online survey, this study explored the beliefs of 249 collegiate athletes representing diverse identities and sports regarding how MH affects sport performance. Regardless of demographic variable, 96.4%–100.0% of participants believed that MH affects sport performance. Three themes were identified: (a) collegiate athletes affirm that MH affects sport performance, (b) collegiate athletes’ perceptions of how MH affects sport performance, and (c) collegiate athletes believe that being a collegiate athlete exacerbates their MH concerns. The universality of endorsement and the themes represent novel findings that warrant further exploration of the MH–sport performance connection.
