Surely this poor lady should have seen a neuro surgeon or similar? Second impact syndrome is very common and can be fatal... Anyone who recieved a blow to the head should be cleared by a specialist and not just a time frame, symptoms in closed head injurys can be very mis leading in my experience.
I seriously worry for the likes of Roynon and Kerr who have already suffered ' deep dense' concussions before, you dont get many, if any second chances with the brain.
