I believe this anxiety creates a greater risk of another head impact. The concussed brain can easily struggle with motor control during stress events. This makes it so that we have less coordination. Less coordination means greater risk of a head impact.

For example, I used to drive an antique car. People would often honk at me to give me a thumbs up. This usually happened at stop lights. I would have to stop to think to get my bearings with the clutch, brake and gas petals.

I have learned that stress and anxiety are the biggest threat I have for coordination issues and an injury.
