چکیده
During the past several years, neuropsychological assessment has become an integral part of comprehensive concussion management programs (7, 8, 15). The majority of research suggests that acute concussion is associated with measurable cognitive deficits that typically resolve within 1 month after the injury (9, 14, 17, 19). However, there is evidence to suggest that newly concussed athletes who have a history of previous concussion may take longer to recover than concussed athletes with no history of previous concussion (13, 22). This may be particularly true of adolescents and younger athletes (16, 18). Moreover, some studies have found that athletes with a self-reported history of multiple concussions may have longlasting cognitive deficits. High school athletes, collegiate athletes, and jockeys with a history of 2 or more distant concussions demonstrate deficits on traditional neuropsychological measures when compared with control athletes with no history of concussion (6, 16, 18, 26). The use of comprehensive computer-based neuropsychological batteries has largely supplanted the use of traditional neuropsychological measures in most concussion management programs. Studies using computer-based tests to examine the association between concussion history and neuropsychological functioning have produced mixed results. In a study examining recovery from concussion, Iverson et al. (13) noted a trend suggesting that athletes with a history of 2 or more distant concussions perform more poorly on a computerized test of memory than athletes with no history of concussion at baseline. In contrast, several recent studies have found no association between concussion hisHISTORY OF MULTIPLE SELF-REPORTED CONCUSSIONS IS NOT ASSOCIATED WITH REDUCED COGNITIVE ABILITIES
