Issue Date: | Dec-2024 | Publication information: | 9(12):1291-1300 | Journal: | Biological Psychiatry | Abstract: | Torture trauma is characterized by intentional uncontrollable acts, but the long-term effects of torture exposure on cognitive control brain mechanisms are unknown. A final sample of 33 torture survivors (TSs) and 44 non-TSs, all with a refugee background, completed a Go/NoGo response inhibition task during functional magnetic resonance imaging scanning. Data-driven independent component analysis identified active networks across the task and on Go, NoGo, and error of commission trials. Groups were compared on within-/between-network connectivity while controlling for demographic and psychological symptom covariates. Secondary analyses investigated whether network connectivity moderated the associations between torture exposure and severity on fear (e.g., re-experiencing) and dysphoria (e.g., anhedonia) posttraumatic stress disorder symptoms. The TS group exhibited decreased connectivity (compared with the non-TS control group) within the posterior default mode network (specifically the left precuneus) and au | URI: | https://nslhd.intersearch.com.au/nslhdjspui/handle/1/42880 | DOI: | 10.1016/j.bpsc.2024.07.025 | ISSN: | 24519022 | Type: | Article | Keywords: | Cognitive Control;Connectivity;Go/NoGo;Refugee;Torture;Trauma |
