My girlfriend has recieved damage to her brain!?

She was leaning out of a window at a hotel and fell out! Her brother caught her before she fell too far, but she still hit her head badly on the way down! Her eye was hit bad and she is blinded in it now (idk if temporary or not), her voice is messed up, but worst of all, she has received damage to her brain! And if it causes her brain to malfunction, it could give her a heart attack or something and kill her! Can someone tell me more about these injuries, particually the brain one, and if my girlfriend will survive?
