This can set your brain up to be overly sensitive to the knock out blow you took. It is knwo by some that sub-concussive impact can cause brain injuries, especially when there are many with concentrations of these sub-concussive impacts during practice sessions.

Just soft-style forms (mostly tai-chi), and no full-contact or full-force sparring. I've had knocks in the head (not martial arts) but no more than a 20-30 seconds LOC (that was once; I was about 10 years old). The most recent hit (before the
BIG one) was about 10 years ago and resulted in 1-2 seconds LOC. I can probably count on one hand, maybe two, how many times I've had any significant knocks to my head.
Edit: Based on my understanding of physics, I'm lucky to be alive after the
BIG one. I don't think sensitization was a factor. Based on what I deciphered from the bruising and cuts (a: I know my own body pretty well and b: I used to be an emergency medical technician) it was a solid hit against a tile/concrete floor.
