Research now suggests that head impacts commonly occur during contact sports in which
visible signs or symptoms of neurological dysfunction may not develop despite those …

Recent work suggests that subconcussive head impacts may contribute to long-term
neurodegeneration; however, the risk thresholds are unknown. It was hypothesized that the …

Initially, interest in sport-related concussion arose from the premise that the study of athletes
engaged in sports associated with high rates of concussion could provide insight into the …

The past decade has seen a marked rise in scientific research on the long-term effects of
RHI and the development of CTE, yet there remain many knowledge gaps that limit …

Purpose To identify and evaluate the evidence that examines subconcussive impacts in
sport-specific settings, and address two objectives: a) to determine how 'subconcussion'is …

Head trauma and concussion in football players have recently received considerable media
attention. Postmortem evidence suggests that accrual of damage to the brain may occur with …

Background: Given questions about “lower thresholds” for concussion, as well as possible
effects of repetitive concussion and chronic traumatic encephalopathy (CTE), and …

It has been understood for decades that certain sporting activities may increase an athlete's
risk of developing a neurodegenerative disease later in life. Not surprisingly, this association …

Abstract HEAD INJURIES INCURRED during athletic endeavors have been recorded since
games were first held. During the last century, our level of understanding of the types of …

Studies of football athletes have implicated repetitive head impact exposure in the onset of
cognitive and brain structural changes, even in the absence of diagnosed concussion …
