Diabetes On The Brain While studies have demonstrated reduced cognitive function in older adults with type 2 diabetes, a new study in the journal Neurology finds the same risks for middle-aged people with the disease.

Study author Meena Kumari, of the International Center for Health and Society in London, said the researchers found poorer cognitive function scores in those who had been diagnosed with diabetes as little as two to five years previously. She said the decline was explained by metabolic abnormalities linked to diabetes.

The average age of those studied was 56. Those with diabetes performed worse on cognitive testing, but those with impaired glucose tolerance, known as pre-diabetes, did not.

More Magnesium, Stronger Bones? Getting more magnesium from diet and supplements may help preserve bone strength and prevent osteoporosis and fractures as people age, finds a study in the Journal of the American Geriatrics Society. The study suggests that higher magnesium intake is linked to higher bone mineral density (BMD) in white men and women. But the study found no such association for black men and women.

Greater BMD has been tied to lower fracture risk.

The study looked at magnesium intake from all sources in relation to BMD for more than 2,000 black and white participants in their seventies. Fewer than 26 percent of the participants met the recommended daily allowance -- 300 milligrams -- for the mineral. Black women got less magnesium from supplements than white women; white men's magnesium intake was higher from all sources than black men's.
