Neurocognitive changes associated with concussion in elite cricket players are distinct from changes due to post-match with no head impact.

Objectives: Determine intra-individual changes in CogSport performance in elite cricket players diagnosed with concussion, and differentiate this from changes which may be attributed to post-match with no head impact.

Design: Retrospective observational study of elite Australian male and female cricket players with diagnosed concussion and prospective cohort study of cricket players with no head impact post-match.

Methods: CogSport performance relative to an individual's baseline was compared between 46 cricket players diagnosed with concussion following a head impact sustained during a match, and 84 cricket players who played a match during which they had no head impact.
