A team of Scottish Doctors have said that cooling the brain of stroke victims can boost recovery and reduce brain damage.
European scientists also have the same opinion that inducing hypothermia in some patients can increase survival chances and reduce the damage in the brain, following a stroke.
The technique in question sends the body to a state of artificial hibernation, where the brain can manage with reduced blood supply, and doctors can use this time to treat the damaged area.
Dr Malcolm Macleod, head of experimental neuroscience at the Centre for Clinical Brain Sciences at the University of Edinburgh, said: "Every day 1,000 Europeans die from stroke - that's one every 90 seconds - and about twice that number survive but are disabled. Our estimates are that hypothermia might improve the outcome for more than 40,000 Europeans every year."
