Ronald Reagan’s son has revealed that he believes his dad suffered from the first stages of Alzheimer’s disease while he was still president. In the book My Father At 100: A Memoir, Ron Reagan says he thinks his dad would have left office had the disease been diagnosed then.
He recalls how Reagan Sr. became uncharacteristically lost for words and looked “bewildered” during the 1984 presidential debates.
He also says his father may have suspected Alzheimer’s in 1986 when he was flying over familiar canyons and could not remember their names.
But White House doctors saw no evidence of the disease while Reagan was president. He was diagnosed in 1994, five years after leaving office.
