The one year comment is not a hard and fast concept. There is no validity to the idea that one is stuck with their level of recovery at one year. We have had many here who took a year to finally stop pushing and give the brain rest so it can heal. Once they finally took the time to give the brain some rest, their recovery improved.

There is no direct science but experience shows that each consecutive concussion usually causes more disabling symptoms with a greater chance of prolonged or permanent symptoms.

Having lived with permanent PCS for 15 years, I can tell you that you should seriously consider avoiding anything that can add to your concussion. I had to make changes to career direction since I was in college and sustained my 4th or 5th concussion. Nobody can say what your future tolerance will be but your long struggle with the current concussion is telling.

What kind of risk does your job include ?
