Is there such thing as a “mild” concussion?

I suppose it depends. Like, how many have already been sustained, and the time between concussion events.

In Purdy's case, he is now more susceptible to another concussion than he was before the one he just had, so in that context, no concussion is mild. But as far as physical effects, the types and degree can vary quite a bit.
