Lay summary

The purpose of this study is to identify the environmental factors and daily habits that are associated with age-related changes in cognitive functions and neural mechanisms.

A number of previous studies have revealed the environmental factors and daily habits that are associated with age-related changes in cognitive functions and neural mechanisms (for review see, Takeuchi et al., 2015, Neuroscientist).

For example, poverty and the habit of longer TV viewing are the examples that are shown to be robustly associated with age-related relative reduction of cognitive functions and neural mechanisms.

However, for some of the daily habits, and environmental factors, the results are divided and still, the controversy exists. Further, there can be unrevealed factors that are associated with age-related cognitive changes and neural mechanisms.

Project length is 36 months. In upcoming years, I plan to conduct analyses that aim to identify factors contributing to each cognitive function and each brain imaging measure one by one.

The publication of analyzed results of each outcome measure will be conducted at once or will be conducted separately, based on the volume and similarity of the obtained significant results.

The environmental factors and daily habits that are associated with longitudinal cognitive and brain changes have been of utmost scientific and social interest. Revealing new factors and showing robustness or confirming effects of previously identifying factors are therefore important.
