How do you diagnose Alzheimer’s disease?

ANSWER

Doctors can’t definitely diagnose Alzheimer's disease until after someone dies, when they can closely examine their brain under a microscope. But tests can rule out other conditions that might cause the same symptoms.

Your doctor will do a physical exam and ask questions about your past and current health. They'll give you a mini mental state exam.

A CT scan can show brain changes that are common in the later stages of Alzheimer's. An MRI can help doctors see if a tumor or a stroke has caused symptoms that look like Alzheimer’s or show brain changes that are linked to the disease.

Neuropsychological testing studies the relationship between the brain and behavior.
