  "account": "Developmental stress triggers distinct brain alterations in males and females, according to a recent study. Researchers from the Max Planck Institute of Psychiatry and international collaborators uncovered how early-life adversity reshapes adult brain function and behavior through different biological pathways in the two sexes. Mice exposed to stress during pregnancy and early life exhibited sex-specific behavioral, neural, and molecular changes. Males displayed reduced behavioral flexibility, depression-like traits, increased stress circuit activity, and elevated metabolic gene expression. Conversely, females retained flexibility, exhibited altered reward sensitivity, lower activation, and stronger network connectivity. These sex-opposite effects were also found in human depression tissue, highlighting the need for sex-informed approaches in psychiatric treatments.",
  "summary": "Exposure to stress during critical developmental windows significantly increases the risk of developing mood and anxiety disorders in adulthood. While women and sexual- and gender-minority groups experience higher rates of adversity and stress-related disorders, the underlying biological mechanisms driving these sex-influenced vulnerabilities remain poorly understood.",
