Gospel and soul music legend Cissy Houston says that despite some family members' optimistic suggestions last month, the prognosis for her granddaughter, music scion Bobbi Kristina Brown, remains dire.

"She's the same," Houston, 81, told "Entertainment Tonight" co-host Kevin Frazier in a video clip posted online Sunday. "She's not progressing at all. She's the same. That's all I can say."

Brown, 22 -- whose parents are the late pop star Whitney Houston and singer Bobby Brown -- has been hospitalized since being found unresponsive in a bathtub at her Roswell, Georgia, town house on Jan. 31. Bobby Brown's attorney, Christopher Brown, said on April 20 that although her condition had improved since she was moved from a hospital to an Atlanta rehabilitation facility in March, her quality of life "will not be known for years to come." Also on April 20, Cissy Houston said her granddaughter has come out of a medically induced coma but has "global irreversible brain damage and remains unresponsive."

Looking weary and speaking slowly, Houston described how "when I go there and look at her, you know, it's very difficult. Her mom and now her," she said, referring to daughter and six-time Grammy Award-winner Whitney Houston, who died in February 2012 at age 48 of accidental drowning in a hotel bathtub due to the effects of cocaine and heart disease. "She's not gone yet," Cissy Houston said of Bobbi Kristina Brown, "but, you know, she's . . . whatever The Lord decides, I'm ready . . . That's His job. That's His territory, you know? And I understand it."

On Friday, Christopher Brown told Newsday in a statement that Bobby Brown and Pat Houston, Whitney Houston's sister-in-law, had been appointed co-guardians of Bobbi Kristina Brown, with responsibility for her care and medical needs. Belinda Hargrove, whom the statement did not identify, was named as conservator for the young woman's assets.
