The late actor and comedian's family would experience "severe mental pain, anguish, and emotional distress" if the records were released, the judge said.
Actor and comedian Bob Saget's death was caused by a blow to the head that he appeared to ignore before going to bed. Medical experts say you should always seek care if you experience a head trauma.
The Saget family says they have been "overwhelmed with the incredible outpouring of love" from his fans, saying the support has been "a great comfort" to them.
John Stamos, Norman Lear and Whoopi Goldberg are among those paying tribute to the actor and comedian, who was found dead in an Orlando, Fla., hotel room on Sunday at age 65.
