BACKGROUND: Secondary injury pathophysiology after sport-related concussion (SRC) is poorly understood. Blood biomarkers may be a useful tool for characterizing these processes, yet there are limitations in their application as a single modality. Combining blood biomarker analysis with advanced neuroimaging may help validate their continued utility in brain injury research by elucidating important secondary injury mechanisms. Hence, the purpose of this study was to evaluate co-modulation between peripheral blood biomarkers and advanced functional brain imaging after SRC...

REVIEW
James Kissick, Nick Webborn
Although Para athletes (the International Paralympic Committee term for sportspeople with a disability) are exposed to a risk of concussion just like their able-bodied counterparts, there has been little research into the incidence of concussion in para sport. Existing assessment and management guidelines and tools have been developed for the general sport population but may not be appropriate for use in some para-athletes. This review examines what is currently known about concussion in para sport and identifies challenges and opportunities in moving knowledge on this topic forward...

BACKGROUND: Although sports-related concussions (SRCs) / mild traumatic brain injuries (mTBIs) in contact sports have recently received much attention, investigation of SRCs in cycling - a sport yielding some of the highest percentages of SRC - remains strikingly limited. In particular, rates of incidence, cycling-specific causes, and potential long-term effects of SRC have not been examined in this sport. Here, a retrospective online survey was used to investigate the incidence and potential long-term effects of SRCs among cyclists...

OBJECTIVES: Sport-related concussion (SRC) research has focused on impaired oculomotor function. The King-Devick (K-D) test measures oculomotor performance and is reported to identify suboptimal brain function. The use of the K-D test in Australian football (AF), a sport involving body contact and tackling, has not been documented. Therefore, the objective of this study was to determine the test-retest reliability and diagnostic accuracy of the K-D test on a sub-elite AF team. DESIGN: Prospective cohort study METHODS: In total, 22 male players (19...

BACKGROUND: Growth hormone deficiency (GHD) is a potential consequence of traumatic brain injury (TBI), including sport-related concussion (SRC). GH stimulation testing is required for definitive diagnosis; however, this is resource intensive and can be associated with adverse symptoms or risks. Measurement of serum IGF-1 is more practical and accessible, and pituitary tumour patients with hypopituitarism and low serum IGF-1 have been shown to have a high probability of GHD. We aimed to evaluate IGF-1 measurement for diagnosing GHD in our local TBI population...

Introduction: The prevalence and possible long-term consequences of concussion remain an increasing concern to the U.S. military, particularly as it pertains to maintaining a medically ready force. Baseline testing is being used both in the civilian and military domains to assess concussion injury and recovery. Accurate interpretation of these baseline assessments requires one to consider other influencing factors not related to concussion. To date, there is limited understanding, especially within the military, of what factors influence normative test performance...
