High glucose levels linked to dementia

Posted by Neill Abayon

Researchers have discovered that those with a high blood sugar level, even if they do not have diabetes, may have an increased risk of developing dementia compared with those who have a normal blood sugar level.

The study, published in the New England Journal of Medicine, analyzed 2,067 participants without dementia aged 65 and over, from a study called Adult Changes in Thought (ACT).

In order to examine the relationship between glucose levels and the risk of dementia, researchers from the University of Washington involved in a Group Health study analyzed average measurements of glycated hemoglobin levels and glucose levels over a period of 6.8 years.

The team compiled specific data from the participants using a Cox regression model - a predictive model that uses time-dependent factors. These included:

Diabetes status
Study cohort
Educational level
Level of exercise
Blood pressure
Status with respect to coronary/cerebrovascular diseases
Atrial fibrillation
Treatment for hypertension.
