Further epidemiological evidence indicates that diabetes onset in late life is a risk factor for dementia. A cohort study involving 169,114 new cases of dementia in Ontario (Canada) found that dementia risk was 16% higher among the subgroup with diabetes. Among the subgroup with diabetes, the risk of dementia was highest in those with pre-existing cerebrovascular disease, peripheral vascular disease and hypoglycaemia.
