Study Identifies Key Proteins and Critical Ages for Brain Aging

Overview

• Researchers identified 13 proteins in blood plasma linked to brain aging, with Brevican (BCAN) and GDF15 emerging as key markers for cognitive health and disease risk.
• The study pinpointed three critical ages—57, 70, and 78—when significant changes in brain aging-related proteins occur, offering potential windows for intervention.
• BCAN is associated with healthier brain structures, while GDF15 is linked to increased risks of dementia and stroke due to its role in stress and inflammation pathways.
• The findings, based on data from nearly 11,000 brain scans and 4,700 blood samples, suggest that blood tests could one day enable earlier detection of brain aging and neurodegenerative diseases.
• Future research aims to explore how these protein levels can be modified through lifestyle changes or targeted treatments to slow brain aging and prevent disease.
