The primary sign of Alzheimer's disease is memory loss. Memory loss from recent discussions or experiences is one of the early warning signals.

A friend or family member may be more likely to identify problems if symptoms worsen. Alzheimer's disease-related brain abnormalities cause increasing problems.
