American football has become the focus of numerous studies highlighting a growing
concern that cumulative exposure to repetitive, sports-related head acceleration events …

Blood-based biomarkers of brain injury may be useful for monitoring brain health in athletes
at risk for concussions. Two putative biomarkers of sport-related concussion, neurofilament …

Repetitive head impacts represent a risk factor for neurological impairment in team-sport
athletes. In the absence of symptoms, a physiological basis for acute injury has not been …

Objectives Recent reports have demonstrated a risk of concussion and subconcussive head
impacts in collegiate varsity and international elite water polo. We sought to characterize …

Recent studies have demonstrated changes in athletes brain imaging across a competitive
season due to repeated head impacts during collision sports. However, there is no data …

Objective: Current evidence for concussions is mixed in water polo players. Surveys suggest
rates as high as 36%, whereas surveillance studies at international competitions often fail to …

Background: Repetitive mild traumatic brain injury (rmTBI) often occurs in individuals
engaged in contact sports, particularly boxing. This study aimed to elucidate the effects of …

Repeated subconcussive head impacts are frequently experienced by athletes involved in
competitive sports, such as boxing. The objective of the present study was to investigate the …

This prospective longitudinal trial aimed to (1) determine the role of head impact exposure
on behavioral/cognitive outcomes, and (2) assess the protective effect (s) of a jugular vein …

Contact and collision sports are believed to accelerate brain aging. Postmortem studies of
the human brain have implicated tau deposition in and around the perivascular space as a …
