"The President is gradually declining with respect to various functions," Dr. Ronald Petersen said on CNN's Larry King Live program Tuesday night. "He's having the difficulties most patients have with Alzheimer's disease."
Petersen, a doctor at the Mayo Clinic in Rochester, Minn., said he visited with the Reagan family in Los Angeles in March and praised the care Nancy Reagan was providing for her husband.
"He is really comfortable and doing well in his environment," Petersen said. "The President is doing as well as he can given the situation of this particular disease."
Reagan, 88, disclosed in 1994 that he had Alzheimer's, an incurable brain disorder.
