Hey guys what are your thoughts on concussions' affect on intelligence/ability to do higher level math? I sustained a few sub-concussions at least last year as part of a boxing club - I never got KO'd, but I definitely took a 2-3 good shots to the head. Do you guys have any anecdotal evidence or personal experience with this? I don't feel any different, but I'm not sure I would notice. These fights were a year ago now. I am in college. I am just worried about it for some reason, it is weighing on me.
