Final answer:
Most Alzheimer's Disease patients die from complications arising from the advanced stage of the disease, which causes a severe decline in bodily functions and overall health.
Step-by-step explanation:
Most Alzheimer's Disease patients die from complications of advanced debilitation. Alzheimer's disease is a progressive neurodegenerative disease that predominantly affects the elderly, leading to memory loss, decline in cognitive functions, and severe brain tissue damage. As the disease advances, patients lose the ability to perform basic functions and become completely dependent on others for care, often leading to complications such as infections, malnutrition, or failure of bodily functions like swallowing. These complications ultimately contribute to mortality.
