Postconcussive Symptoms Are Associated With Compensatory Cortical Recruitment During a Working Memory Task

摘要

BACKGROUNDThe severity of sports-related concussion is often characterized by the number and severity of postconcussive symptoms (eg, headache, dizziness, difficulty concentrating). Although the level of postconcussive symptoms after injury is believed to index the severity of the neurological insult sustained, studies examining the relationship between symptom severity and neural functioning in concussed athletes remain rare.
