While imaging brain studies can’t show us what we’re thinking, they can show us comparatively how two brains are performing from two different groups. Neuroscientists use such comparisons to form hypothesis about brain behavior. Using neuroimaging techniques to study aging — techniques such as …

I hope this isn’t right!
Now that the technology is there it’d be interesting to see data over time comparing people who do mental activities daily vs. those who do not at say 5 year intervals. In any event there are some things that we can do to maintain a healthier body and mind. Read the book “7 Steps to a Healthy Brain” by Dr. Paul Winner.
Men over 90 are less likely to develop Alzheimers disease
U.S. researchers have announced findings that suggest that men over 90 years of age are much less likely to develop Alzheimer’s disease and other forms of dementia. 911 people aged over 90 participated in the study and found that 28% of the men and 45% of the women were currently suffering from a form of dementia. The study also showed that dementia rates in men remained constant as men moved through their 90′s whereas women’s dementia rates noticeably increased as they age.
Another explanation for these findings includes the fact that women may live longer after receiving a dementia diagnosis than men. Statistically, women live longer than men even when in the best of health. That said, there are few men in the population who live to 90 years old which may account for the results of the study. More studies will need to be done to determine the risk factors for dementia, but also to find new treatments and eventually, a cure for this crippling disease.
Health Care experts are predicting a rise in the number of dementia diagnoses in the coming years. This is due to the increase in the elderly population in many countries. Having an experienced health care provider can help you notice changes in your loved one’s medical conditions that may indicate the onset of dementia.
