Kind: research · Impact: medium

## In brief

- A large PET imaging study reports that people who develop Alzheimer's disease before age 65 tend to show more widespread buildup of toxic tau protein in the brain.
- The same study reports faster spread of tau in early-onset cases compared with those who develop the condition later in life.
- The findings were published in Science Translational Medicine, according to PsyPost's coverage.

## Why it matters

The results suggest early-onset and late-onset Alzheimer's may differ in how quickly tau pathology spreads, which matters for how researchers interpret disease progression and design studies.
