Alzheimer's disease (AD), the most prevalent class of dementing illness, is a leading cause of death and affects over 5 million individuals in the US. Like most dementing illnesses, AD cannot be effectively prevented and is incurable. Progressive memory loss and impairment of reasoning and judgment are its main symptoms. For this reason, people in the early stages of AD are encouraged to engage in advance care planning (ACP) while they are still competent to appoint a surrogate decision maker and meaningfully participate in ACP discussions with the surrogate.
