Kind: research · Impact: low

## In brief

- In older adults without memory problems, tau protein buildup in the brain tends to precede a rise in mild depressive symptoms.
- The study found little evidence that mood changes drive tau accumulation.
- The findings were published in the Journal of Psychology research outlet named in the source.

## Why it matters

The results suggest that subtle mood changes in late life may be an early signal of Alzheimer's-related brain changes, which could matter for how clinicians and researchers think about depression in older adults.
