OBJECTIVE Clinical observations suggest that a history of previous concussions may cause a slower recovery of neurological function after recurrent concussion episodes. However, direct examination of this notion has not been provided. This report investigates the differential rate of restoring the visual-kinesthetic integration in collegiate athletes experiencing single versus recurrent concuss...

Persistent post-concussion syndrome caused by mild traumatic brain injury has become a major cause of morbidity and poor quality of life. Unlike the acute care of concussion, there is no consensus for treatment of chronic symptoms. Moreover, most of the pharmacologic and non-pharmacologic treatments have failed to demonstrate significant efficacy on both the clinical symptoms as well as the pat...

T he incidence and consequences of concussion among athletes have comeunder intense scrutiny in the setting of the untimely deaths of several notable professional athletes. Brain injury in its most severe forms has been exhaustively studied, butwehave onlybegun to scratch the surface of our understanding of milder injuries.Historically, these types of injuries have been difficult to study becau...

A debate has ensued about the long-term consequences of mild traumatic brain injury, the 'signature injury' of the Iraq and Afghanistan Wars. Most epidemiological studies have found that mild traumatic brain injury is unrelated to unspecific post-concussion symptoms based on self-reported symptoms. A longitudinal study, in this issue of the Journal, using objective tests has demonstrated that m...

Traumatic brain injury, specifically concussion, is prevalent in contact sports. In the United States (US) each year, 170 million adults participate in physical recreational activities, and 38 million children and adolescents participate in organized sports. The Centers for Disease Control estimate that in this group ~1.6 to 3.8 million concussions occur annually. Recent class-action lawsuits i...

OBJECTIVE Determine changes in cognition and post-traumatic stress disorder (PTSD) symptoms in subjects with traumatic brain injury (TBI) exposed to 2.4 atmospheres absolute (atm abs) breathing 100% oxygen vs. sham (1.3 atm-abs air). METHODS Fifty randomized subjects completed a total of 30 exposures. A concussion history was taken, then baseline, post-series, and six-week follow-up immediate...

After Zackery Lystedt’s brain injury, “he couldn’t speak for nine months,” his father said. Thirteen months later, “he could move his left arm a little; it took two years to get rid of the feeding tube and four years before he could move his right leg purposefully.” Zackery had suffered a concussion during a high school football game in 2006, but “was twice returned to play and collapsed 60 sec...

School learning and performance is arguably the critical centerpiece of child and adolescent development, and there can be significant temporary upset in cognitive processing after a mild traumatic brain injury, also called a concussion. This injury results in a cascade of neurochemical abnormalities, and, in the wake of this dysfunction, both physical and cognitive activities become sources of...
