I’ve heard this is more common than you think due to chokes
I'm notorious for fighting in chokes and have a rep of "being hard to choke out." I bait my open neck so I can pass or set things up. I always joke that I can hold out in strangles because my head is so big and my brain so small, I have the Homer Simpson peanut brain.
Over the past two years or so my wife and those around me notice some cognitive changes that are not for the better. I'm becoming more forgetful, and my brain just pauses for moments at a time and I forget what I was doing.
We were curious if this was partly due to bjj. I stopped striking a couple years back as my reflexes have dulled considerably.
I'm curious if I have suffered something like this in the past
