For healthcare professionals

A growing body of research has identified that outcomes associated with TBI may differ depending on how the TBI was sustained. In this study, researchers examined whether concussion mechanism of injury (high-level blast [HLB] vs impact) affects the likelihood of persistent sleep problems in members of the military after deployment. Findings suggest that those with HLB-induced concussions are more likely to report persistent sleep problems than those with impact-induced concussions, particularly in the presence of PTSD and/or depression. These findings underscore the need to monitor and treat sleep issues during TBI recovery. Medical providers may consider additional follow up for those with HLB-induced concussions and comorbid PTSD or depression to ensure adequate treatment for sleep issues as a pathway to promote recovery and overall well-being.

Lingering and difficult-to-detect post-concussion sensorimotor impairments may contribute to an increased likelihood of subsequent musculoskeletal injury in the year after concussion for some adolescent athletes, particularly in the immediate months following return to sport. Currently, clinicians are unable to identify who is at higher risk of subsequent musculoskeletal injury following concussion. In this study, researchers sought to test for the first evidence of suppressed general startle reactivity in adolescent athletes with a recent concussion compared to those without a concussion history. Results suggest that general startle reactivity is a potential biomarker for concussion and may provide additional insight into the mechanisms of concussion and increased incidence of subsequent injuries.

Growing evidence suggests that peripheral biomarkers of inflammation, such as interleukin (IL)-6 and 1IL-1 receptor antagonist (IL-1RA), are elevated acutely following concussion and potentially associated with slower recovery. The objective of this study was to determine the association of markers of inflammation with clinical symptoms and recovery following acute concussion in collegiate athletes and military service academy cadets. The researchers found that the association of symptoms and inflammatory markers was only significant at the 12- to 36-hour post-injury window. This study highlights that peripheral inflammation is associated with psychological symptoms observed post-injury, which have implications for observed clinical recovery and return to activity after concussion. Current results do not provide strong support for a potential prognostic role for these markers.

ACEP recruits the field's top experts and thought leaders to develop tools that clinicians can trust and deploy in the clinical setting. The evidence-based, clinical content provided in these tools helps clinicians provide the best possible patient care in the emergency department. Download the ACEP Mobile app to access clinical content and tools for emergency medicine physicians to utilize while providing care in the ED. This tool includes information on the recognition, evaluation and management of mTBI / concussion and other ED relevant topics.

Although headache is the most common complaint in those with concussion, other symptoms including vestibular, vision, and cognitive are often present and can be overlooked during the medical interview. This webinar recording discusses these symptoms and basic strategies for management.
