We previously found that children of parents with depression showed impaired performance on a task of emotional categorisation. Aims To test the hypothesis that children of parents with depression would show abnormal neural responses in the anterior cingulate cortex, a brain region involved in the integration of emotional and cognitive information. Method Eighteen young people (mean age 19.8 years) with no personal history of depression but with a biological parent with a history of major

Results Controls showed significant activation in the pregenual anterior cingulate cortex to both positive and negative words during the emotional Stroop task. This activation was absent in FH+ participants. Conclusions Our findings show that people at increased familial risk of depression demonstrate impaired modulation of the anterior cingulate cortex in response to emotionally valenced stimuli.
