Abused Children Similar to War Vets

Children who have been abused or witnessed violence suffer similar trauma to war veterans…

LONDON (Reuters) ­ Children exposed to family violence show the same pattern of activity in their brains as soldiers exposed to combat, scientists said on Monday. In a study in the journal Current Biology, researchers used brain scans to explore the impact of physical abuse or domestic violence on children’s emotional development and found that exposure to it was linked to increased activity in two brain areas when children were shown pictures of angry faces.

Previous studies that scanned the brains of soldiers exposed to violent combat situations showed the same pattern of heightened activity in these two brain areas ­­ the anterior insula and the amygdala ­­ which experts say are associated with detecting potential threats. This suggests that both maltreated children and soldiers may have adapted to become “hyper­aware” of danger in their environment, the researchers said. “Enhanced reactivity to a…threat cue such as anger may represent an adaptive response for these children in the short term, helping keep them out of danger,” said Eamon McCrory of Britain’s University College London, who led the study.

Kids put in institutions have different brain compositions than kids in foster care

In new research published in the journal JAMA Pediatrics, researchers looked at brain differences between Romanian children who were either abandoned and institutionalized, sent to institutions and then to foster families, or were raised in biological families.

Kids who were not raised in a family setting had noticeable alterations in the white matter of their brains later on, while the white matter in the brains of the children who were placed with a foster family looked pretty similar to the brains of the children who were raised with their biological families.

Researchers were interested in white matter, which is largely made up of nerves, because it plays an important role in connecting brain regions and maintaining networks critical for cognition. Prior research has shown that children raised in institutional environments have limited access to language and cognitive stimulation, which could hinder development.

These findings suggest that even if a child were at a risk for poor development due to their living circumstances at an early age, placing them in a new caregiving environment with more support could prevent white matter changes or perhaps even heal them.

More studies are needed, but the researchers believe their findings could help public health efforts aimed at children experiencing severe neglect, as well as efforts to build childhood resiliency.
