A clinical perspective on the revised criteria for diagnosis and staging of Alzheimer’s disease

The 2024 update for Alzheimer’s disease (AD) criteria introduces a new biomarker classification system with blood biomarkers and revised staging.

International clinical guidelines are being developed to enhance diagnostic and prognostic accuracy.
