Higher HemoblobinA1c Levels Linked to Cognitive Decline Over Time

HgbA1c (hemoglobin A1c) is a blood test that reflects average blood sugar levels over the previous three months. From a 2018 study:

In this community-based population, we observed a significant trend for cognitive decline over a 10 year period among individuals aged ≥50 years with normoglycaemia, prediabetes or diabetes at baseline. Additionally, HbA1c levels were linearly associated with subsequent cognitive decline in memory and executive function (but not orientation) irrespective of diabetes status at baseline.
