Parenthood may help the brain stay young

A study of nearly 38,000 adults found that having more children is associated with increased synchronization between certain brain regions. This effect was observed in both male and female parents, suggesting it results from parenting rather than pregnancy. The strongest connection was in a brain network that helps interpret others' thoughts and behaviors. Researchers suggest that the complex, long-lasting experience of raising children may protect against age-related decline in brain coordination.
