By Kathryn DoyleReuters Health. Reuters Health - In a group of cognitively normal adults age 55 and older in Singapore, those with certain cardiovascular risk factors were more likely than others to develop mild cognitive impairment or dementia over a six year period. In five communities in Singapore between demehtiathe researchers studied specific foods linked to dementia than 1, adults. More than half were female. Overall, had the constellation of risk factors consistent with metabolic syndrome.

Over time, participants developed mild cognitive impairment, including 14 percent of those with metabolic syndrome and 8 percent of those without it. Those with type 2 diabetes, central obesity, unhealthy cholesterol levels or metabolic syndrome at the beginning of cementia study had an increased risk of developing mild cognitive impairment over time compared to others. Diabetes was tied to a more than tripled increase in risk, while metabolic syndrome, central obesity and unhealthy cholesterol increased the risk of cognitive impairment by about 50 percent.

But for the risk of mild cognitive impairment progressing to dementia, metabolic syndrome increased the risk more than fourfold, even more than type 2 diabetes. Of participants who had mild cognitive impairment at the beginning of spfcific study, 14 progressed to dementia, including about 8 percent of people with metabolic syndrome compared to specific foods linked to dementia about 2 percent of those without metabolic syndrome, as reported in JAMA Neurology.

Physical inactivity, poor diet, smoking, and mental stress are known to increase the risk of metabolic syndrome and are now increasingly acknowledged to increase the risk of dementia as define average speed and average velocity in what case can the magnitude, Ng said.

Insulin plays a vital role in brain metabolism and memory, Ng said, and people with diabetes or the risk factors leading to diabetes may be resistant to insulin. Metabolic syndrome was associated with cognitive impairment before but not after age 75, Forti noted.
