Kind: research · Impact: medium

## In brief

- A study of more than 1,800 older Australians found that lifetime trauma was associated with higher likelihood of mild cognitive impairment or dementia.
- People with lifetime trauma performed worse on working memory and executive function tests.
- The article reports an association; it does not establish that trauma causes these conditions.

## Why it matters

The findings add to evidence that past trauma is a risk factor for cognitive decline in older adults, which may matter for how clinicians screen and support older patients.
