A week after the news of his brain hemorrhage was first reported, Bret Michaels’ doctor at the Barrow Neurological Institute at St. Joseph’s Hospital in Phoenix is speaking about his condition. The former Poison frontman’s neurosurgeon, Joseph M. Zabramski, told E! Online, “There is no doubt that Mr. Michaels’ condition is serious… Bret’s sheer will to live and fully recover is undeniable. He has an unbelievable fight in him and told me what kept him alive at the moment of the hemorrhage was that he ‘did not want his family to wake up and see him lying unconscious in the middle of the floor.’” Zabramski went on to say that he’s had several conversations with Michaels since he arrived at the facility last week. Michaels’ medical team at Barrow will hold a press conference on his condition Tuesday at noon.
