Reagan suffered from the advanced stages of Alzheimer's Disease
Former US President Ronald Reagan has died, aged 93, after reports in recent days that his health had taken a turn for the worse.
He had suffered from Alzheimer's disease, and had not been seen in public for several years.
He died at his home in California, according to a friend quoted anonymously by the Associated Press.
He was US president from 1981 to 1989 and had lived longer than any other holder of the post.
Mr Reagan revealed in November 1994 that he was suffering from Alzheimer's disease, which destroys brain cells and causes memory loss. Since then, he retreated to his home in Los Angeles, where he had been nursed by close members of his family.
