Theoretically how much brain damage can a human sustain and still just about get away with it?

I mean still be able to control their arms and legs and communicate?

Answers:
depends which parts of the brain are damaged. Different parts of the brain control different functions, from higher cognitive skills right down to basic "breathe in, breathe out" stuff. The answer is "Not much if it hits the right areas."
Wave your arm a minute?
judging from the US's last 3 presidents - quite a lot
i guess the best person to answer this question would be George Bush, as he has been brain dead for years but stil manages to move his arms and legs and still has some limited speech skills
5 cubic inches, depending in hwich areas of the brain it is.
ask george bush . he's just about got away with it!
It depends hugely on the part of the brain that is damaged. Interesting question though. Be good to see if anyone can give a comprehensive answer.
It's hard to measure quantitatively, but you're getting close.
I'd say whatever theory you come up with - test it out and let us know.
me lose brain
oh oh
I SAW A TV PROGRAM WHERE THIS YOUNG KID LOST ABOUT HALF HIS BRAIN AND HE WAS FUNCTIONING WELL. HE HAD A HUGE DENT IN HIS HEAD BUT HE WAS OK OTHER WISE. HE ALSO HAD TO WEAR A BIKE HELMET EVERYWHERE HE WENT.
The question and answer are so ambiguous it's dreadful you'll think of such a thing. Princess Diana didn't make it. How could you measure the limits of concusion and brain damage? Any about of injury to the brain is a bad thing and may have long term effects.
It would specifically be determined by what part of the brain was injured.
There is a well known case from here in Vermont where a man was working in a quarry and had a crowbar blown up thru the bottom of his jaw and it came out of his head behind his left eye. Amazingly he lived, but reports were that he suffered a reverse lobotomy, and was a very mean, vulgar man after wards.
Some traumatic brain injuries can leave a person less int elegant, but still able to preform ' activities of daily life.'
It really depends which area of the brain is damaged. In saying that we are supposed to only be using 7-10% of our brains as it is. So 90% - but I'm not volunteering to find out for sure!
it varies from different people. my big bro has metal plates in his head he got attacked by catholics in Belfast and left for dead they beat him with crow bars and baseball bats around the head. docs told us he would not survive he would be badly brain damaged. 15 yrs on he is 33 and normal the only thing that is noticeable is the scar from ear to ear where they had to open the head to put the plates in. it depends how strong you are
It isn't so much the degree as where the damage is sustained, that will determine the loss of capacity and functionality.
It depends on the degree of damage and how old you are. There are plenty of cases of children with almost an entire hemisphere missing who grow up to lead normal lives. The brain is quite plastic, especially in the young, and there brain learns to adapt (although the child can have severe forms of dyslexia). Adults aren't as lucky, and even small lesions to the brain from a mini-stroke can cause significant impairment if they fall in the frontal regions of the brain, the motor cortex, and the mid-brain areas.
thats a very sad question for me as my daughter has severe brain damage........
