administered PET scans to a sample of 10 children adopted from Romanian orphanages and compared them with 17 normal adults and a group of 7 children. Assessments showed mild neurocognitive impairment, impulsivity, and attention and social deficits. Specifically, the Romanian orphans showed significantly decreased activity in the orbital frontal gyrus, parts of the prefrontal cortex/hippocampus, the amygdala and the brain stem.
