There's some research indicating that music can induce positive emotions in comatose patients. Maybe other stuff like having family visits , watching TV(?) Can do the same . The main problems I thought they should have is isolation - but maybe one sided family/nurse visits is enough to deter that ? And also no control - but this doesn't necessarily leads to depression if you learn to accept it, and if the environment is good.
