Raised blood sugar is linked to dementia even in people without diabetes, a study has shown.
A study of 2,000 older patients found a close link between glucose levels and dementia risk
Scientists found a close association between glucose levels and dementia risk in a group of 2,000 older patients aged 65 and over.
Even in apparently healthy participants, a blood sugar level increase from 100 to 115 milligrams per decilitre (mg/dl) raised the risk of dementia by 18%.
In those with diabetes, whose blood sugar tends to be higher than average, the risk was higher. A diabetes patient with a glucose reading of 190 mg/dl was 40% more at risk than one with a level of 160 mg/dl.
The findings appear in the New England Journal Of Medicine.
