The brains of children raised in violent families resemble the brains of soldiers exposed to combat, psychologists say.
They’re primed to perceive threat and anticipate pain, adaptations that may be helpful in abusive environments but produce long-term problems with stress and anxiety.
“For them to detect early cues that might signal danger is adaptive. It allows them to react, to try and avoid the danger,” said psychologist Eamon McCrory of University College London. However, “a very similar neural signature characterizes quite a few anxiety disorders.”
In a study published Dec. 5 in Current Biology, McCrory’s team used functional magnetic resonance imaging, or fMRI, to measure blood flows in the brains of 43 children exposed to violence at home as they looked at pictures of sad or angry faces.
Previous studies have shown that abuse affects kids’ brains; as they grow up, abused children become adults with high levels of aggression, anxiety, depression and other behavioral problems. But according to McCrory, the new study is the first to use fMRI to study the form of those changes.

I was subject to a lot of violence growing up . . .
Now I have a depression/anxiety disorder . . . but only occasionally aggressive.
Nuff said.
