Looking up info for a post concussed person and I'm getting nothing

What is "concussed person".

@beebaby concussion I meant

You need info on concussions, like symptoms?

@beebaby basically he got into a car accident back in August and like it's not getting better and Idk what to do

Has this person went to the doctor and been re evaluated

@beebaby nope. Supposedly going to go today but I don't believe it

Definitely should get seen if he is having complications. They have machines that can so concussion assessments
