In the last decade of his life, Reagan lived in seclusion as he battled a diagnosis of Alzheimer’s disease. In 1994 he revealed his diagnosis to the nation in a handwritten letter, discussing his and Nancy's decision to make it public.
"In opening our hearts," wrote Reagan, "we hope this might promote greater awareness of this condition. Perhaps it will encourage a clearer understanding of the individuals and families who are affected by it."
He wrote that he would continue to enjoy the outdoors and corresponding with friends and supporters, while acknowledging that he expected the road ahead to be difficult for his family. He closed the letter by thanking the American people for letting him serve as president. He wrote:
“I now begin the journey that will lead me into the sunset of my life. I know that for America there will always be a bright new dawn ahead.”
