Joan Rivers has been moved out of intensive care.
A family source exclusively tells ET that doctors are continuing to bring the comedienne out of her medically induced coma very slowly but that it's still very much a waiting game. But there is some good news.
"Preliminary tests appear to rule out brain dead," the source says. "There seems to be some function."
This comes just after Melissa Rivers confirmed that her mother has been moved out of intensive care and into a private room. In a statement Wednesday morning, Melissa said: My mother has been moved out of intensive care and into a private room where she is being kept comfortable. Thank you for your continued support."
On Sunday, doctors started the process of bringing Joan out of a medically induced coma.
She remains on life support.
Melissa, 46, is staying positive throughout Joan's medical emergency ET learned Tuesday.
"There is only one outlook Melissa is looking at now -- She's like, 'When my mother wakes up…,' 'When my mother see this and that …' There is only one trajectory she sees this going in the direction of, which is positive," a family source told ET. "She refuses to acknowledge any other outcome than Joan coming out of this.”
"I know my mother would be overwhelmed by the continued outpouring of kindness and I want to thank everyone for keeping us in their prayers," Melissa said Tuesday.
