How is Alzheimer’s diagnosed?

Doctors use several methods and tools to help determine whether a person who is having memory problems has “possible Alzheimer’s dementia” (dementia may be due to another cause), “probable Alzheimer’s dementia” (no other cause for dementia can be found), or some other problem. To diagnose Alzheimer’s, doctors may: Ask the person and a family member or friend questions about overall health, use of prescription and over-the-counter medicines, diet, past medical problems, ability to carry out daily activities, and changes in behavior and personality Conduct tests of memory, problem solving, attention, counting, and language Carry out standard medical tests, such as blood and urine tests, to identify other possible causes of the problem Perform brain scans, such as computed tomography (CT), magnetic resonance imaging (MRI), or positron emission tomography (PET), to rule out other possible causes for symptoms Learn what happens after diagnosis and the benefits of early diagnosis on our website.
