According to this article, the onset of mild cognitive impairment (often considered a potential precursor to Alzheimer’s Disease) afflicts men more than women. Mild cognitive impairment is defined as a display of memory difficulties and other mild cognitive deficits that are above and beyond what would typically be expected, given the person’s age and level of education. Over 2,000 individuals were assessed as part of the study, as well as a family member or other person familiar with the person’s functioning. The researchers found:
* 16.7 per cent of the group had mild cognitive impairment.
* Men were 1.6 times more likely to have mild cognitive impairment than women.
* This statistic was the same regardless of the men's level of education or marital status.
Interestingly, the study also found men and women have the same levels of full dementia. This suggests that while men show signs of impairment earlier, their decline is less steep, compared to women. In other words, there is a delayed progression from normal cognitive functioning to dementia for men, when compared with women.
In addition, the article also mentions other lifestyle factors that influence the onset and progression of cognitive difficulties, including fitness level and diet.
