Having diabetes or metabolic syndrome could mean cognitive decline and memory problems for seniors, according to a study published in the journal Neurology.
Research done in France looked at people over 65 and found that those with metabolic syndrome did poorer on memory tests.
“Our results suggest that management of metabolic syndrome may help slow down age-related memory loss, or delay the onset of dementia.” noted study author Christelle Raffaitin, MD, of the French National Institute of Health Research in Bordeaux, France.

Metabolic Syndrome Linked to Memory Loss in Older People
Older people with larger waistlines, high blood pressure and other risk factors that make up metabolic syndrome may be at a higher risk for memory loss, according to a study published in the February 2, 2011, online issue of Neurology, the medical journal of the American Academy of Neurology.
Metabolic syndrome was defined as having three or more of the following risk factors: high blood pressure, excess belly fat, higher than normal triglycerides (a type of fat found in the blood), high blood sugar and low high-density lipoprotein (HDL) cholesterol, or “good” cholesterol. Metabolic syndrome has also been tied to increased risk of heart attack. (Learn the Benefits of This Fruit: Nature’s Little Blue “Pills” Fight Heart Disease)
For the study, 7,087 people age 65 and older from three French cities were tested for metabolic syndrome. A total of 16 percent of the participants had metabolic syndrome. Participants were given a series of memory and cognitive function tests two and four years later. The tests included a memory test, a test of visual working memory and a test of word fluency.
Researchers found that people who had metabolic syndrome were 20 percent more likely to have cognitive decline on the memory test than those who did not have metabolic syndrome. Those with metabolic syndrome also were 13 percent more likely to have cognitive decline on the visual working memory test compared to those who did not have the syndrome. Specifically, higher triglycerides and low HDL cholesterol were linked to poorer memory scores; diabetes, but not higher fasting blood sugar, was linked to poorer visual working memory and word fluency scores.
“Our study sheds new light on how metabolic syndrome and the individual factors of the disease may affect cognitive health,” said study author Christelle Raffaitin, MD, of the French National Institute of Health Research in Bordeaux, France. “Our results suggest that management of metabolic syndrome may help slow down age-related memory loss, or delay the onset of dementia.” (More on Pill Advised: Can B Vitamins Help Prevent Dementia? )
The study was conducted under a partnership agreement between the French National Institute of Health Research (INSERM), the University Victor Segalen Bordeaux 2 and Sanofi-Aventis. The 3C Study was supported by the National Fund for Health Insurance for Employees, Directorate General of Health, Mutual General Education, the Institute of Longevity and Aging, Regional Councils of Aquitaine and Bourgogne and the Foundation of France. The Lille Genopole was supported by an unconditional grant from Eisai.
