Amyloid PET Scans Predict Intermediate/High Alzheimer’s Pathology
Key Highlights
Medicine · Neurology
This study investigates the clinical accuracy of positive amyloid PET scans by correlating them with autopsy-confirmed Alzheimer’s disease neuropathologic change (ADNC). Researchers found that 90% of individuals with a positive scan had intermediate or high levels of ADNC at autopsy, confirming the scan’s strong predictive value. For the subscriber, a PhD candidate studying placebo mechanisms in chronic pain at the Brain and Mind Centre, this work reinforces the importance of neurobiological validation for clinical biomarkers, a principle applicable across all domains of neuroscience.
