This study looked at the differences in ImPACT baseline cognitive composites and symptom scores in athletes with self-reported Autism Spectrum Disorder (ASD). Previous research has shown that other neurodevelopmental groups (ADHD, learning disabilities (LD), and ADHD+LD) demonstrate differences in both cognitive composites (lower memory composites and slower speed composites) and symptoms scores (overall higher symptom reporting).
This study matched a majority of its participants on age, sex, and sport. There were a total of 435 participants in 5 matched groups (ASD, ADHD, LD, ADHD+LD, neurotypical).
The only differences in the ASD group was lower Visual Motor Speed composite (when compared to neurotypical and ADHD groups; medium effect sizes).
