Hello I am 14. I had my concussion about a year ago from now and a few months after my accident I started noticing little dizzy sessions I had. I also noticed having problems with remembering certain words and grammar at school, slowed reaction and processing time, and weirdly I lost my sense of humor. I have had very little improvement of my PCS and I was wondering what the chances of this being a permanent problem? But happily I do admit that my dizzy sessions are becoming more sparse and my humor is very slowly coming back.
