There are still many unanswered questions about postconcussion syndrome (PCS) in sports and recreation. The predictors of PCS are unknown, although a history of previous concussion has been suspected. ⋯ More than 80% of PCS cases had at least 1 other previous concussion. Half of the athletes with PCS were ≤ 18 years of age. PCS was associated with 7.6 symptoms per athlete. The duration of PCS and the number of symptoms were not related to the number of previous concussions, loss of consciousness, or return to play. Further research on treatment and prevention of PCS is required.

The risk of radiation-induced optic neuropathy (RION) is the primary limitation of single-fraction stereotactic radiosurgery (SRS) for many patients with parasellar lesions. ⋯ The AVP in patients without prior radiation treatments can safely receive radiation doses up to 12 Gy with a low risk of RION. Although additional studies are needed to better delineate the normal tissue complication probability of the AVP, adherence to the AVP radiation tolerance guidelines developed 20 years ago (8 Gy) limits the applicability and potentially the effectiveness of single-fraction SRS for patients with lesions in the parasellar region.

As unstructured play declines, organized sports leagues have become a highly popular form of physical activity in young people. As concussive injuries are garnering increased media attention and public awareness, there is a growing concern for athlete safety. Although athletic trainers and physicians play a large role in keeping athletes healthy and safe, this article investigates nontraditional, multidisciplinary teams that are involved in promoting athlete safety, including the role of equipment makers, coaches, referees, governing bodies of sport, lawmakers, and fans. As opposed to a focus on diagnosing or managing concussive injuries, this article seeks to promote injury prevention strategies.
