As increasing numbers of people with type 1 diabetes live into old age, a large new study has found they face almost three times the risk of developing dementia compared to people without the condition – raising urgent questions about how the disease affects the brain over time.
To put this in context, of the 283,772 people in the study, 5,442 had type 1 diabetes. Of those, 144 people went on to get dementia. That is 2.6% of that group.
