Step-by-step explanation:
An example of an early symptom of Alzheimer's disease is difficulty in remembering appointments. This can be attributed to the disruptive memory loss that is commonly associated with the disease.
Other symptoms include confusion about time or place, difficulty planning or executing tasks, poor judgment, personality changes, and problems with smelling certain scents. While some of these symptoms may also occur in people who are aging normally, the severity and longevity of these symptoms determine whether a person is suffering from Alzheimer's.
