RT Journal Article SR Electronic T1 Concussion history predicts self-reported symptoms before and following a concussive event JF Neurology JO Neurology FD Lippincott Williams & Wilkins SP 1516 OP 1518 DO 10.1212/01.WNL.0000142088.32204.82 VO 63 IS 8 A1 Bruce, Jared M. A1 Echemendia, Ruben J. YR 2004 UL http://n.neurology.org/content/63/8/1516.abstract AB The authors evaluated how history of concussion affects symptom reporting prior to and after sustaining a concussion. At baseline, athletes with a positive concussion history reported more current symptomatology than athletes who had never been concussed. At 2 hours postinjury, concussed athletes with a history of previous concussion (PC) reported fewer symptoms than concussed athletes with no previous concussion history (NPC). By 1 week postinjury, however, PC athletes reported more symptoms than NPC athletes.
