Metabolic Syndrome Linked to Memory Loss in Older People

03.02.2011
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.

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.”

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.

The American Academy of Neurology, an association of more than 22,500 neurologists and neuroscience professionals, is dedicated to promoting the highest quality patient-centered neurologic care. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as Alzheimer’s disease, stroke, migraine, multiple sclerosis, brain injury, Parkinson’s disease and epilepsy.

Im Focus: It’s All in the Mix: Jülich Researchers are Developing Fast-Charging Solid-State Batteries

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.

The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
