Alzheimer's disease usually begins with

A) hallucinations and delusions.
B) symptoms of violence.
C) mild memory loss.
D) heart disease.

Alzheimer's disease typically begins with mild memory loss, especially of recent events. Other early symptoms may include difficulty in performing familiar tasks, problems with language, disorientation to time and place, poor or decreased judgment, problems with abstract thinking, misplacing things, changes in mood or behavior, changes in personality, and loss of initiative. Hallucinations, delusions, and symptoms of violence are not common early symptoms of Alzheimer's disease. Heart disease is not related to the onset of Alzheimer's disease.
