Diagnosing Alzheimer's disease

Interviews with friends and family

Doctors and other healthcare professionals may ask your family members or friends questions about you and your behavior.

Healthcare professionals look for details that don't fit with your former level of function. Family members or friends often can explain how your thinking skills, functional abilities and behaviors have changed over time.

These tests, the physical exam, your age and the length of time symptoms have been going on often are enough to diagnose Alzheimer's dementia. When the diagnosis isn't clear, your healthcare team may need to order more tests.
