lowered baseline neuropsychological performance. A significant

interaction was found between LD and history of multiple concussions

and LD on 2 neuropsychological measures (Trail-Making Test, Form

B [P=.007] and Symbol Digit Modalities Test [P=.009]), indicating

poorer performance for the group with LD and multiple concussions

compared with other groups. A discriminant function analysis using

neuropsychological testing of athletes 24 hours after acute in-season

concussion compared with controls resulted in an overall 89.5%

correct classification rate.

Conclusions Our study suggests that neuropsychological

assessment is a useful indicator of cognitive functioning in athletes

and that both history of multiple concussions and LD are associated

with reduced cognitive performance. These variables may be

detrimentally synergistic and should receive further study.

The management of mild traumatic brain injury (MTBI; eg,

concussion, defined as a traumatically induced alteration in mental

status not necessarily resulting in loss of consciousness) in athletics

is currently one of the most compelling challenges in sports

medicine. Despite the high prevalence1 and potentially serious

outcomes2, 3 associated with concussion, systematic research on

this topic is lacking. Many sports medicine practitioners are not

satisfied with current return-to-play and treatment options, which do

not appear to be evidence based.4-6 There is also little research

examining whether long-term cognitive morbidity is associated with

concussion. Past research with nonathletes revealed that repeated

concussions appear to impart cumulative damage, resulting in

increasing severity and duration with a second MTBI occurring within

48 hours.7 No data were presented which addressed more long-term
