Do Sideline Concussion Assessments Predict Subsequent Neurocognitive Impairment After Sport-Related Concussion?

Cerebrovascular reactivity impairment after sport-induced concussion.

PURPOSE This study evaluated cerebrovascular reactivity (CVR) after a sport-induced concussion, also called mild traumatic brain injury (mTBI), by monitoring middle cerebral artery blood velocity (vMCA) with transcranial Doppler ultrasonography and simultaneous end-tidal carbon dioxide (PETCO(2)) measurements. METHODS Thirty-one athletes (16-25 yr old) participated in this study. The particip...

Sport-related concussion.

Sport-related concussion is a common injury in children and adolescents. Athletes seldom report concussive symptoms, which makes the diagnosis a challenge. The management of sport-related concussion has changed significantly over the last several years. The previously used grading systems and return-to-play guidelines have been abandoned in favor of more individualized assessment and management...

The "value added" of neurocognitive testing after sports-related concussion.

BACKGROUND Neurocognitive testing has been endorsed as a "cornerstone" of concussion management by recent Vienna and Prague meetings of the Concussion in Sport Group. Neurocognitive testing is important given the potential unreliability of athlete self-report after injury. Relying only on athletes' reports of symptoms may result in premature return of athletes to contact sport, potentially expo...

School Attendance and Symptoms in Adolescents After Sport-Related Concussion

The epidemiology of sport-related concussion.

Concussions and head injuries may never be completely eliminated from sports. However, with better data comes an improved understanding of the types of actions and activities that typically result in concussions. With this knowledge can come improved techniques and rule changes to minimize the rate and severity of concussions in sports. This article identifies the factors that affect concussion...
