International audience. Childhood adversity has been observed to engender structural changes in the hippocampus and corpus callosum associated with increased risk for depression in childhood and early adulthood. This study investigated this association in the elderly. Corpus callosum area and hippocampal volume were measured from structural MRI in 427 community dwelling elderly. Information on childhood adversity was obtained in the course of a clinical examination using a questionnaire covering multiple aspects of abuse. Multivariate analyses found a significant increase in corpus callosum area and hippocampal volume in subjects exposed to mental disorder in parents and poverty, respectively. No association was found with childhood sexual and physical abuse.
