Type 2 diabetes and prediabetes are associated with accelerated brain aging, according to a new study from Karolinska Institutet in Sweden published in the journal Diabetes Care.
Karolinska InstitutetAug 28 2024 The good news is that this may be counteracted by a healthy lifestyle .
The study included more than 31,000 people between 40 and 70 years of age from the UK Biobank who had undergone a brain MRI scan . The researchers used a machine learning approach to estimate brain age in relation to the person's chronological age. Having an older-appearing brain for one's chronological age can indicate deviation from the normal aging process and may constitute an early warning sign for dementia. On the positive side, it seems that people with diabetes may be able to influence their brain health through healthy living."
Repeated MRI data were available for a small proportion of the study participants. Follow-up MRI scans are ongoing and researchers are now continuing to study the association between diabetes and brain ageing over time.
