Bobbi Kristina Brown's condition remains the same nearly six weeks after she was placed in a medically induced coma since she was found unresponsive in a bathtub in her suburban Atlanta home on Jan. 31, a source told Extra on Friday. An expert told the celebrity news magazine that the 22-year-old’s condition may not fully recover.

The daughter of late Whitney Houston and Bobby Brown has shown no signs of improvement and neither the family nor the hospital has released any update on her current condition. A neurosurgeon, who has never treated Bobbi Brown, told Extra that the family should remain hopeful and that it could take about three to six months in such cases for a patient to come out of the coma.

“To expect a full recovery is absolutely not possible,” Dr. Sasan Yadegar, neurosurgical director with Dignity Health Northridge Hospital and Trauma Center, reportedly said, adding that the aspiring actress could face many challenges after she is out of the coma.

Bobbi Kristina has made little to no significant improvement since being placed in a medically induced coma. The last update on Bobbi Kristina’s condition came on her 22nd birthday last week when her aunt, Patricia Houston, posted a message on

“Today is Bobbi Kristina’s 22nd birthday and we ask you to continue to keep her in your prayers as she is still fighting the battle of her life,” Pat Houston wrote at the time.

Meanwhile, in an interview with Dr. Phil, Bobbi Kristina's boyfriend, Nick Gordon, opened up about his anguish over his girlfriend’s condition. He also admitted to his substance abuse, while his mother claimed that Gordon tried to commit suicide. Gordon, who is reportedly under investigation over Bobbi Kristina's condition, checked into rehab after the interview.
