A startling study published in the New England Journal of Medicine reveals a link between high blood sugar levels and an increased risk for dementia, even in people who are not diabetic. Authors of the study speculate that having higher blood sugar levels can increase the risk for vascular disease, which, in turn, contributes to a higher likelihood of cognitive deterioration. There may also be other metabolic factors that come into play, such as insulin resistance affecting brain cells.
For the purposes of the study, 2,067 participants (839 men and 1,228 women) from the Adult Changes in Thought study were analyzed and stratified according to diabetes status (232 participants had diabetes, while 1,835 did not), and then adjusted for other variables such as age, sex, educational level, and level of exercise. During a median follow-up of 6.8 years, dementia developed in 524 participants (74 who had diabetes and 450 who did not). Among the participants who did not have diabetes, having higher-than-average blood sugar levels within the preceding five years was related to a statistically increased risk of dementia.
Researchers found that elevated blood sugar levels at any level increased the risk of dementia; however, the higher the number, the greater the risk of damage to the brain.
Blood sugar is considered as too high if it is higher than 130 mg/dl before a meal or higher than 180 mg/dl two hours after one. People with these levels are diagnosed to have hyperglycemia and it is the defining characteristic of all types of diabetes. The most common symptoms of hyperglycemia are: excessive urination (polyuria), excessive thirst (polydipsia), and excessive hunger (polyphagia).
Drugs that are used to manage blood sugar levels are often associated with adverse side-effects. Fortunately there are natural steps you can take to lower your blood sugar levels.
Lastly, remember that it is extremely important that you monitor your blood sugar levels regularly. Measuring them on a regular basis will also help you control them.
