The article's sidebar adds (and I will comment later):
People with mild cognitive impairment often have mild memory difficulties but usually no other sign of Alzheimer's.
The 10 warning signs of Alzheimer's:
Severe memory loss.
Difficulty doing familiar tasks.
Problems talking or writing.
Confusion about the time or place.
Loss of judgment.
Problems with abstract thinking.
Misplacing things. People with Alzheimer's might put items in unusual places.
Changes in mood or behavior.
Changes in personality.
Loss of motivation.
