Tommy, I am surprised your doctor has not told you no more contact sports. This concussion is taking you so long to recover, your next will likely take even longer.

It's not like you have a chance to make a living playing basketball from a Div 3 program. I gave up contact sports in 10th grade after my third concussion as suggested by my neuro. Since then, I have suffered 11 more concussions over 40+ years. You want to end taking any obvious risks because life has enough risk of more concussions. Someday, you may hit that magic number of concussions that drastically changes your life permanently. I hit that number at 46 years old and had to give up most driving.

The risk is not worth it.

Was your neuropsych with a doctor or with a computer ? How long did it take ?
