Atlanta ( CNN ) More family members are coming to Atlanta to see Bobbi Kristina Brown in the hospital . On Friday , grandmother Cissy Houston arrived at Emory University Hospital , a source close the family told CNN . She 's the mother of the late musical superstar Whitney Houston , Bobbi Kristina 's mother . Other family members , including Bobbi Kristina 's father , singer Bobby Brown , have been in Atlanta for days . Bobbi Kristina , 21 , was found facedown in a bathtub full of water in her Atlanta area home last Saturday . The Roswell police spokeswoman said Brown was `` unresponsive , meaning not breathing , no heartbeat . '' Doctors have placed her in a medically induced coma , a source close to the family said soon after she was hospitalized . The status of her brain function wo n't be known until sedatives are reduced , the source told CNN . A week after she was rushed to the hospital , details of her condition are scare . Sources close to the family say she opened her eyes briefly last Monday and also suffered seizures that same day . It was not immediately clear what medical significance these reported events have in Brown 's case . Meanwhile , the three-year anniversary of Whitney Houston 's death approaches . On February 11 , 2012 , she was found dead in a bathtub at the Beverly Hilton hotel near Los Angeles hours before she was to attend a pre-Grammy Awards party . A coroner ruled her death an accidental drowning , with heart disease and cocaine use listed as contributing factors . Brown is her only child . After Houston 's death , Bobbi Kristina talked of pursuing a career in acting and music , just like her mother . In 2012 , she reportedly lobbied for a role in a planned biopic of her mother 's life . Lifetime 's `` Whitney , '' which was directed by actress Angela Bassett , debuted in January 2015 , but the Houston family was not involved . Concerns that she may have substance abuse issues , as her mother did , intensified in July 2014 after a picture was posted on her Instagram account showing a young woman who looked like Brown appearing to be smoking from a bong . Bobbi Kristina Brown `` was not breathing '' when Nick Gordon -- the man she has referred to as her husband -- and a friend , who 's been identified as Maxwell Lomas , found her inside her townhouse in the Atlanta suburb of Roswell . They called 911 and performed CPR until emergency crews arrived and took over , police spokeswoman Lisa Holland said . Nobody knows what caused Brown 's unresponsiveness , Holland said , but police consider it a medical incident at this time . She said investigators had found nothing to indicate it was drug- or alcohol-related . Bobbi Kristina Brown had said she was married to Gordon , who had lived with Houston and her daughter since he was 12 years old . However , Bobby Brown attorney Christopher Brown said the two were never married . CNN 's Carolyn Sung , Lisa Respers France , Eliott C. McLaughlin , Sunny Hostin , Nischelle Turner and Nick Valencia contributed to this report .
