Scientists have found having babies may help protect your brain. At least in rats, a new study shows mothers are mentally sharp longer than the female rats who have never had babies.
Scientists at the University of Richmond compared the memory skills of three groups of female rats. In running the rats through maze tests at different points in life, they found those who'd mothered the most babies performed better on memory tests than other female rats. The rats ranged in age up to two years. Two rat years equals about 70 and 80 human years.
Researchers say since female rats and women experience the same hormonal changes with reproduction their findings suggest the potential of a similar Protective benefit in people. It was presented Thursday at the annual meeting of the Society of Neuroscience.
