Stress 'changes brains of boys and girls differently'
Very stressful events affect the brains of girls and boys in different ways, a Stanford University study suggests.
A part of the brain linked to emotions and empathy, called the insula, was found to be particularly small in girls who had suffered trauma. But in traumatised boys, the insula was larger than usual. This could explain why girls are more likely than boys to develop post-traumatic stress disorder (PTSD), the researchers said. Lead study author Dr Megan Klabunde said it was important to consider the different physical and emotional reactions to stressful events. "It is important that people who work with traumatised youth consider the sex differences.
"Our findings suggest it is possible that boys and girls could exhibit different trauma symptoms and that they might benefit from different approaches to treatment." And she added: "There are some studies suggesting that high levels of stress could contribute to early puberty in girls." Dr Klabunde said they would now look at other regions of the brain connected to the insula to see if they could detect similar changes.
