What is it about?
This paper shows the association of age, male sex, diabetes mellitus, stroke, and hypertension with cognitive decline at baseline in TILDA participants. Although the speed of cognitive decline was higher in TILDA participants who have diabetes, the increment in the decline rate was too small to be detected in the first few years. Instead, this accelerated decline was only captured over six years from baseline, confirming that diabetes has a slow and insidious effect on cognition.

Why is it important?
These findings are not a novelty, as diabetes has already been associated with declined cognition in other populations. However, this is the first study looking at declined cognition in diabetic participants over time in the TILDA cohort.
Perspectives
This study reinforces the importance of screening and managing DM in community-dwelling older adults to prevent future cognitive impairment.
