^^^Not trying to contradict what you said, just building off of it...saying likely Aldo doesn't have long term brain damage...but concussion is likely and must be treated appropriately so as to not lead to permanent dain bramage as can occur if concussed individual sustains an additional head injury shortly after first head injury.
EDIT: I posted this message to clarify that I wasn't hating on your post, it seems I can, at times, come off a bit adversarial, it's likely that I simply Don't Play Well With Others for some reason but I'm trying : )
