Among married mothers who worked, the rate of memory loss did not vary according to whether participants worked continuously, took a few years off to raise their children or took many years off to raise their children, Mayeda said. What was important, she said, was that they worked for a wage at some point.
So from the study, it generally didn't show a variation in wether women took many years off from paid work to those who worked continuously.
So, as long as you are married and have worked for a wage at some point in your life, your risk is reduced ???.?.
