Some positive news surrounding Bobbi Kristina's condition. After being found unresponsive in an Atlanta bathtub, sources report that her family has reason to remain hopeful. reports:

In the weeks since Bobbi Kristina Brown was found unresponsive in her bathtub, her future has remained uncertain. The 21-year-old daughter of Whitney Houston and Bobby Brown continues to be unresponsive, kept in a medically induced coma since Jan. 31.

“There will be a sign of hope, and then nothing,” says a family source. “Every day, we wonder if this will be the day that we get good news.”

Doctors hope to find some answers soon. Their latest medical decision: to wean Bobbi Kristina off the medication that keeps her in the coma. “We’re all hoping and praying that this will give us some answers,” says the family source, who adds that Brown’s condition remains “severe.”

Subhashini Ramesh, a professor of NeuroCritical Care at Georgia Regents University, explains the reasoning to PEOPLE. “They take them off a medically induced coma for two reasons – because the underlying problem has improved, or to simply get a sense of what the patient is able to do for themselves.”

Dr. Ramesh, who is not treating Brown, says that her recent tracheostomy signifies one bit of positive news.

“Obviously, she did not meet the criteria for brain death if she underwent a tracheostomy,” Dr. Ramesh says. “She still could have a devastating injury, though.”

For now, Bobbi Kristina remains on life support, which includes a ventilator and feeding tube. “We’re hoping for a significant change soon,” says the family member, “but we know that it may not change anything.”
