What are the common changes observed in people who suffer from Alzheimer's disease (AD)?

Answers will vary. Alzheimer's disease (AD) progresses in several stages. At first there are subtle cognitive and personality changes in which people with AD have trouble managing finances and recalling recent events. As AD progresses, people find it harder to manage daily tasks, select clothes, recall names and addresses, and drive. Later, they have trouble using the bathroom and maintaining hygiene. They no longer recognize family and friends or speak in full sentences. They may become restless, agitated, confused, and aggressive. They may get lost in stores, parking lots, even their own homes. They may experience hallucinations or paranoid delusions, believing that others are attempting to harm them. People with AD may eventually become unable to walk or communicate and become completely dependent on others.
