My cousin was in an induced coma for 3 weeks after brain injury in a road traffic accident. His family were advised to turn off the life support, as he'd be a 'vegetable' (the exact medical definition, in Australia) if he survived. He survived, had fantastic support from the health service in Oz, learned to walk, talk etc all over again. He was left with (well controlled)epilepsy, sightly impaired speech and short term memory problems. But, he built a very good life with his then girlfriend, they married and had children. He was the stay home parent, whilst his wife worked. His injury was serious, he was left with a plate in his head, and a noticeable deep crater shaped hole on the front of his skull onto his forehead. So, maybe there is hope for Schumacher, though I agree, it does sound very serious.
