Pregnancy changes the brain in multiple ways

Neuroscientist Liz Chrastil recently participated in a groundbreaking study that provided a detailed map of how a woman's brain changes throughout pregnancy. The study, published in Nature Neuroscience, followed Chrastil through in vitro fertilization, pregnancy, and postpartum, conducting MRI brain scans and drawing blood to observe the changes in her brain as sex hormones fluctuated.

The research team found that more than 80% of the regions studied had reductions in gray matter volume, similar to changes that occur during puberty. While this may sound concerning, researchers believe it reflects the fine-tuning of neural circuits in preparation for motherhood.

The study, although focused on one individual, marks the beginning of a larger international research project that aims to scan the brains of hundreds of women to gain insights into disorders like postpartum depression. By studying the inner regions of the brain as well as the cerebral cortex, researchers hope to understand the full extent of brain changes experienced during pregnancy and postpartum.

The Maternal Brain Project, supported by the Ann S. Bowers Women's Brain Health Initiative and the Chan Zuckerberg Initiative, seeks to use data from a large number of women to predict and potentially prevent postpartum depression. The research has implications for understanding the neurobiology of pregnancy and addressing historical gaps in women's health research.

Overall, the study offers valuable insights into how the brain adapts to motherhood and lays the groundwork for future research on the neurological changes associated with pregnancy. By taking a comprehensive approach to studying brain changes during pregnancy, researchers hope to improve our understanding of maternal health and potentially enhance support for new mothers.
