    We read with interest Raikes et al.’s [1] study suggesting subjectively measured insomnia and daytime sleepiness increases risk of concussion in college athletes. This is a noteworthy preliminary study which highlights the apparent bi-directional link between concussion and sleep. Nevertheless, we observed that the authors of this study did not describe how concussion was measured, nor analyse whether subjective sleep complaints were associated with the severity of concussion. We feel this is a limitation of the study as potential mechanisms to explain their results are difficult to formulate.
