Childhood Trauma Linked to Altered Brain Pathways and Adult Anhedonia, Study Finds
New research indicates that experiencing trauma during childhood can lead to changes in brain pathways, specifically those linked to reward and motivation, which may contribute to anhedonia in adulthood. Anhedonia is characterized by a reduced ability to experience pleasure or a lack of motivation. A study led by Kathleen O'Brien at Temple University and Vishnu Murty at the University of Oregon utilized fMRI to examine hippocampus interactions with motivation-related brain areas in a large cohort of human participants. The findings suggest that individuals with childhood trauma who also exhibited disrupted hippocampus pathways experienced higher levels of anhedonia compared to those with childhood trauma but no such disruption.
