Dr. Darby Saxbe breaks down the science behind ‘dad brain’

We’ve all heard of “mom brain,” but it turns out dads go through some pretty big changes, too! Research shows that fatherhood can actually change a man’s brain, body, hormones and mental health. Dr. Darby Saxbe, a clinical psychologist and professor of psychology at USC, joined us to break down the science behind “dad brain” and how becoming a father can shape men’s lives. Her book, “Dad Brain: The New Science of Fatherhood and How It Shapes Men’s Lives,” is available now. For more information, visit DarbySaxbe.com.
