Diabetes May Be Linked to Risk of Alzheimer’s

 

This risk also appears to be heightened among people with prediabetes — people who are on the verge of developing diabetes.

Exactly how diabetes and dementia are linked is not fully understood. But the new findings add to growing evidence that what is good for our hearts may also be good for our brains.

The study is published in Neurology.

In the study, 1,017 people 60 and older were given a glucose tolerance test to see if they had diabetes or prediabetes. Researchers from Kyushu University in Fukuoka, Japan, followed the participants for around 11 years and then tested them for dementia.

In that time, 232 people developed Alzheimer’s disease and other forms of dementia.

Forty-one of 150 people with diabetes developed dementia. By contrast, 115 of the 559 people without diabetes developed dementia. An increased risk of dementia was also found in people with prediabetes.
