Maternal depressions alter the baby’s brain structure
According to a study from Singapore, if a pregnant woman is depressive, this affects her baby’s brain structure. The children have a life-long increased risk of developing a mental disease, warn scientists in “Biological Psychiatry”.

157 pregnant women were involved in a study undertaken by the National University of Singapore. They were asked to complete a questionnaire during the 26th week of pregnancy to assess their level of depression. Within two weeks of birth, the brains of newborns were examined using magnetic resonance imaging and diffusion tensor imaging scans.
