Longitudinal PET imaging links education, BMI, and hypertension to the spread of Alzheimer’s tau pathology.
Key Details
- 1Study used 18F-AV-1451 PET scans on 162 amyloid-positive participants across cognitive stages.
- 2Findings: Higher BMI, lower education, and severe hypertension associated with greater tau-level-rise.
- 3Genetic factors affected tau-speed (spatial distribution of tau).
- 4Both modifiable (lifestyle) and non-modifiable (genetic) risk factors were assessed against tau spread.
- 5The research was presented at the 2025 SNMMI Annual Meeting.
Why It Matters
By identifying modifiable risk factors measurable via advanced PET imaging, this research offers a path to potential lifestyle interventions for slowing Alzheimer’s progression, and contextualizes the use of molecular imaging in both clinical research and treatment monitoring.
