Higher A1C, Worse Memory
For older adults with diabetes, controlling blood glucose may help keep memories alive. At four points between 2006 and 2012, researchers studied 950 adults over age 60 with diabetes and 3,469 of their peers without diabetes. They tested participants’ memory by reading them a list of words and then asking them to recall as many as they could, both immediately and again after five minutes. Among people with diabetes, higher A1Cs (a measure of average blood glucose levels over time) were associated with poorer memory at the beginning of the study and a steeper drop in memory over six years.
