THURSDAY, Feb. 19 (HealthDay News) — A rise in blood sugar levels causes poorer brain function in people with type 2 diabetes, according to a study that included nearly 3,000 people aged 55 and older at 52 sites in Canada and the United States.

The participants, who were part of a larger study on cardiovascular risk in diabetes, underwent cognitive tests designed to measure several aspects of memory function. The researchers found that a 1 percent increase in A1C levels (average blood glucose levels over a period of two to three months) was associated with slightly lower scores on tests of psychomotor speed, global cognitive function, memory and multi-tasking.

However, no link was found between tests scores and daily blood glucose levels, which are measured by a fasting plasma glucose test.

The findings appear in the February issue of Diabetes Care.

"One of the little-known complications of type 2 diabetes is memory decline leading to dementia, particularly Alzheimer's disease," principal investigator Dr. Jeff Williamson, of Wake Forest University Baptist Medical Center, said in a news release from the university.

"This study adds to the growing evidence that poorer blood glucose control is strongly associated with poorer memory function and that these associations can be detected well before a person develops severe memory loss," he said.

Previous research has shown that people with diabetes are 1.5 times more likely than those without diabetes to experience cognitive decline and develop dementia.

Williamson said that "people with type 2 diabetes and their health-care providers need to be careful in situations where there is education and teaching about diabetes care, as patients may need a little more time to absorb and process information."

And he urged people with diabetes to "be open to having a family member periodically making sure they are keeping track of managing their diabetes through monitoring, diet, exercise and medication."

My husband always teases me because my memory sucks to be quite honest, I'm good short term but my medium term isn't so hot and my long term is okay for the most part. Things that happened within the last 5-8years are the fuzzy ones for me. He means no harm with his teasing I assure you but sometimes it makes me wonder where those memories went.

this is so true. When my BS were sky high, I was totally clueless. i was working in the ER at one time and went in and took vitals on a patient. When I came out of the room the MD asked me what the patients vitals was. I looked at him like I had no clue what he was asking me. He told me to get in room one and they drew my blood. It was in the 800's. I was admitted to ICU. Thank God they know I was diabetic. I did have many times though when high blood sugars effected me, like seeing out of my glasses I couldn't. I in the past 15 years have had good blood sugars and when you let them go to high it puts you in a frightening situation…Debe
