Scientists are just beginning to explore the more complex biological differences that set men and women apart. Among their most current findings is the discovery that differences between the sexes are factors in how the brain deteriorates with age.
French researchers examined nearly 7,000 people over the age of 65. None of the people included in this general population sample had dementia, but approximately four in ten were deemed to have mild cognitive impairment at the start of the study. After two and four year follow-ups, the researchers found that 6.5% of those deemed to be cognitively impaired developed dementia. (J Neurol Neurosurg Psychiatry. 2008; doi 10.1136/jnnp.2007.136903). But that isn’t all—the results also showed that risk factors differed between the sexes.
Specifically, men with mild cognitive impairment were more likely to be overweight, diabetic, or to have had a stroke. And of those who had suffered from a stroke, they were almost three times as likely to eventually develop Alzheimer’s.
As for the women, those with mild cognitive impairment were more likely to be in poor general health, disabled, suffering from insomnia or to have a poor support network. Additionally, depressed women were twice as likely to progress toward Alzheimer’s.
The Anti-Aging Bottom Line: Alzheimer’s affects more than 4.5 million Americans, but evidence is mounting that diet, exercise and nutritional supplements all play a role in its prevention. Stay healthy by keeping your weight in check, exercising, eating right and taking supplements for brain health and overall nutritional balance.
