When Reagan left office in 1989, he held an approval rating of 68%, matching those of Franklin D. Roosevelt, and later Bill Clinton, as the highest ratings for departing presidents in the modern era. He was the first president since Dwight D. Eisenhower to serve two full terms after the five prior presidents did not. Although he had planned an active post-presidency, Reagan disclosed in November 1994 that he had been diagnosed with Alzheimer's disease earlier that year. Afterward, his informal public appearances became more infrequent as the disease progressed. He died at home on June 5, 2004. His tenure constituted a realignment toward conservative policies in the United States, and he is an icon among conservatives. Evaluations of his presidency among historians and the general public place him among the upper tier of American presidents.
