Stress hormones can lead to enhanced cognitive abilities in children

Posted by in categories: biotech/medical, education, neuroscience

Researchers at the Max Planck Institute of Psychiatry have investigated how stress hormones affect the early development of brain cells in the cerebral cortex of the fetus. The cortex is the crucial area of the brain for thinking. The team was able to demonstrate causal links between stress hormones and altered brain structure, which relate to higher levels of educational attainment later in life.

The hormone group of glucocorticoids is crucial for the regulation of our metabolism and , but also for the development of organs such as the brain and lungs before birth. The hormones are released in response to stress and can travel from the mother to the fetus. One of the best-known is cortisol. Synthetic forms are prescribed, for example, in pregnancies at high risk for preterm delivery in order to help the maturation of the fetal lungs.

“We found that glucocorticoids, when present early in in the first or early second trimester, increase the number of a particular type of brain cells that are formed very early in development (called basal progenitor cells)”, reports Anthi C. Krontira, who led the study published in Neuron. “These are cells that are important for the growth of the cerebral .”
