With MCI, people may begin to notice changes in cognitive functions beyond common age-related changes. Severe levels of impairment can lead to losing the ability to understand the meaning or importance of something and the ability to talk or write, ultimately resulting in the inability to live independently.
What is the Link Between Cognitive Decline and Diabetes?
Uncontrolled blood glucose in diabetes is a risk factor for vascular complications such a nephropathy—diabetic kidney disease and retinopathy—diabetic eye disease. High glucose levels cause damage to the small blood vessels in the kidney and eye.
Research suggests that elevated glucose levels are also associated with damage to the small blood vessels in the brain. The risk of these complications can be reduced with good blood glucose control.
How Can You Preserve Cognitive Function?
You can preserve cognitive function by prevention or control of diabetes and high blood pressure, reduction in smoking, increase in exercise and eating a healthy low-fat diet. If you have prediabetes losing at least 5 percent of body weight – just 10 pounds in someone weighing 200 pounds – can help avoid diabetes and cut the risk.
If you already have diabetes, checking your blood glucose often and writing down the results will tell you how well you are managing your diabetes. Generally, blood glucose should be monitored two to four times a day, either before meals or two hours after meals and at bedtime. But each case is unique. Talk to your doctor and diabetes educator about how often you should check your blood glucose.
The American Diabetes Association guidelines for optimal blood glucose control to prevent complications are:
Before meals 70 mg/dl – 130 mg/dl
1 to 2 hours after meals less than 180 mg/dl
