Alzheimers begins with mild memory problems, attention lapses and difficulty in recalling words thus making communication more difficult. As the disease progresses simple tasks become difficult or impossible to achieve. Distant memories begin to fade, familiar faces often go unrecognised and changes in personality become noticeable.
During the final years of his presidency, in the mid to late 1980s, Ronald Reagan revealed bouts of forgetfulness during public engagements. It was not until 1994 however that doctors agreed a final diagnosis of Alzheimers. In fact Alzheimers cannot be confirmed until autopsy.
