A new Mayo Clinic study found that the prevalence of mild cognitive impairment was 1.5 times higher in men than in women. The research, part of the Mayo Clinic Study of Aging, also showed a prevalence rate of 16 percent.
The research is published in the September 7, 2010, print issue of NeurologyÂ®, the medical journal of the American Academy of Neurology.
Doctors are looking very closely at a possible clue to explain the prevalence of MCI in men.
Study author Ronald Petersen, MD, PhD, with the Mayo Clinic in Rochester, Minn., said, "When we look at the men who have Mild Cognitive Impairment, they tend to have more of the vascular risk factors than women do, such as high blood pressure, diabetes, smoking."
Study after study comes back with the implication that what is good for the heart is good for the brain, and this one seems to add the insight that the women simply have more heart-healthy habits than the men. The good news is that heart-healthy habits are well-understood. People can take a lot of well-established preventative measures to help protect themselves and improve their odds.
