According to TMZ, the only change in treatment is that doctors tried weaning her off certain medicines to see if she might react but nothing happened as she's in the same condition she's been in for weeks.
It’s also reported that there have been signs of organ deterioration but she's still basically in the same, unresponsive condition and that doctors performed tracheotomy procedure not because she was getting better, but because it's standard operating procedure when a patient might linger in a comatose state for a long period of time.
The 21-year-old is said could possibly hang on for a long period of time in the same state, despite signs of organ failure but It's ultimately up to her father, Bobby Brown to decide how long she'll live in that state.
