New research published on August 21, 2026, reveals that structural brain alterations can be detected via MRI up to seven years before the appearance of amyloid plaques in Alzheimer's patients.
This breakthrough suggests that early diagnostic imaging could significantly improve the window for intervention, allowing doctors to identify high-risk individuals long before clinical symptoms manifest.
The study highlights the potential for MRI technology to serve as a primary screening tool, potentially replacing more invasive or expensive diagnostic methods in the future.
