There is no single test that can determine if you have Alzheimer's disease, dementia, or a blend of both.
—Melissa Batchelor, PhD, RN, FNP, FGSA, FAAN

Have you ever wondered why it takes so long to get to a diagnosis of Alzheimer’s disease or another type of dementia?

The good news is that it should take a bit of time – because it is a diagnosis of exclusion – meaning any other issues have to be ruled out. So it’s a little more complicated than a single test can tell us.

In today’s episode, I will walk you through the types of tests, exams, and screenings that should be done to help your provider get to a diagnosis. Stay tuned!

▶ How is Alzheimer’s Disease and Dementia Diagnosed?

Investigating possible causes and early diagnosis is important because:
While there is no cure, there may be another underlying cause that is treatable/ reversible, or you have time to make lifestyle modifications that may help manage the disease.

It can explain why you’re having a harder time with your memory or decision-making

You can make decisions about your future and communicate those to your loved ones

There isn’t a single test. Any type of dementia is a “diagnosis of exclusion.”
