I realize this isn't the place for this, but this is the community I frequent so this is where I wanted to ask the question. If mods really feel strongly about it they can delete the thread. Basically was wondering how much boxing/sparring can cause brain damage/lowered IQ? I've recently been going at it harder with sparring and have been getting some light headaches. I asked my some people about it and they told me I should take some time off as I could start developing some brain damage/lowered IQ from this. As with everything people tell me, I assume it's broscience until I run it by Sherdog, but I really don't want to risk brain damage or lowered IQ or anything of the sort for a sport I do recreationally and for fun. So, what's the consensus (if any) on this? Does boxing and the repeated head hits cause lowered IQ/brain damage or is this only an issue for professional boxers with a bunch of fights? Also, if I got a head scan now would this be able to show any possible brain trauma from boxing or would I need a point of comparison?
