Moody teenage years might be caused by significant prenatal stress. Researchers at Central European Institute of Technology analyzed MRI and mood-related data from a cohort of 93 young adults and found that higher prenatal stress predicted altered brain states and poor mood in young adulthood. Early intervention for young children who were subjected to stressful events during pregnancy could reduce the risk of mental illness in young adulthood.
