The risk of dementia increases the younger people develop diabetes, new research has found.
Prediabetes is when blood sugar is high but has not developed into type 2 diabetes. Most people who go on to develop diabetes first pass through this stage of prediabetes.
There was a three times greater risk of dementia for those developing type 2 diabetes before the age of 60, according to the recent study published in the medical journal Diabetologia.
