Abstract
•We studied cognition in the landmark Finnish Diabetes Prevention Study.•Cognition was assessed 9 years after the end of the lifestyle intervention.•Randomization to the lifestyle arm was not related to cognition.
We studied cognition in the Finnish Diabetes Prevention Study (DPS), a trial of lifestyle intervention that prevented diabetes in persons with impaired glucose tolerance. Cognition was similar in the randomization arms 9 years after the intervention in 364 participants, suggesting that the intervention did not benefit cognition.
