The Unintended Harms of Alzheimer's Biomarker Testing: Why Amyloid Isn't a Diagnosis
By

Summary
This article critically examines the growing trend of Alzheimer's Disease biomarker testing, arguing that testing for amyloid plaques does not equate to diagnosing Alzheimer's Disease. It highlights that many individuals with amyloid buildup never develop dementia (citing cognitive reserve research showing 25-67% of those meeting autopsy criteria were nondemented). The article warns about the unintended harms of biomarker testing, including psychological distress, stigma, discrimination, and unnecessary treatments. It also discusses how families may struggle with these diagnoses in a digital era where information spreads rapidly, and suggests psychologists can help patients and families navigate the uncertainty and emotional impact of biomarker results.
