Things are changing quickly in the Alzheimer’s space. We now have biomarkers that can reasonably approximate the degree of amyloid build-up in the brain with a simple blood test. We have two new FDA-approved medications that reduce that amyloid buildup and modestly slow down the progression of the disease. So, the question becomes, what, if anything, should we do differently in the primary care setting to diagnose the disease?

On today’s podcast, we’ve invited Nathaniel Chin back to the GeriPal podcast to talk about what primary care needs to manage this new world of Alzheimer’s disease effectively. Nate is a geriatrician and clinician-scientist at the University of Wisconsin, as well as the host of the Wisconsin ADRC's podcast, "Dementia Matters." In each bi-weekly episode, he interviews Alzheimer's disease experts about research advances and caregiver strategies. Nate also wrote a NEJM piece last year on “Alzheimer’s Disease, Biomarkers, and mAbs — What Does Primary Care Need?”

We address the following questions with Nate:

• Has anything changed for the primary care doctor when diagnosing Alzheimer’s? How should we screen for cognitive impairment?

• Does a good history matter anymore?

• What’s the role of assessing function?

• What do we do with those who have only subjective cognitive complaints?

• Can’t we skip all this and just send some blood-based biomarkers?

• What is the role of the amyloid antibody treatments?

Lastly, take a look at the following if you want to take a deeper dive into some of the other articles and podcasts we discuss:

• First, two competing definitions of what is Alzheimer’s:

• • Alzheimer Disease as a Clinical-Biological Construct—An International Working Group (IWG) Recommendation

  • Revised criteria for diagnosis and staging of Alzheimer's disease: Alzheimer's Association Workgroup

• Alzheimer's Association clinical practice guideline for the Diagnostic Evaluation, Testing, Counseling, and Disclosure of Suspected Alzheimer's Disease and Related Disorders (DETeCD-ADRD): Executive summary of recommendations for primary care

• Podcasts we mentioned

• • Prevention of Dementia: A Podcast with Kristine Yaffe
