Bobbi Kristina Brown was briefly taken out of her medically-induced coma this week, but after suffering several seizures, doctors placed her back on medication and in a coma, reports CNN.

Family sources tell TMZ that doctors tried weaning Bobbi Kristina off certain meds to see if she might react, "but nothing happened" and that she's "in the same condition she's been in for weeks." The insiders added that Bobbi Kristina "could hang on for a long period of time in the same state, despite signs of organ failure."

Brown was found facedown in her bathtub four weeks ago this Saturday, and two days after the accident she was put under a medically-induced coma. Last week doctors performed a tracheotomy on the aspiring singer, who will be turning 22 on March 4. TMZ's sources added that Bobbi Kristina, the only daughter of Bobby Brown and the late Whitney Houston, is not getting better and it's up to Bobby to decided when to take his daughter off of life support.

Though it was initially labeled as an accident, police have now launched a criminal investigation into the incident after discovering new evidence. Brown's boyfriend Nick Gordon is at the center of the investigation, and family members have prohibited him from visiting her in the hospital.
