Low levels of a brain protein during pregnancy can cause depression in the mother and low birth weight in the baby, a study has found.The findings showed that brain-derived neurotrophic factor (BDNF) commonly known to regulate moods, is also vital for the placenta and a baby’s brain development. It constantly changes during pregnancy.

A dip in this protein’s levels is behind the depression, which is a common condition during pregnancy.

“Our research shows BDNF levels change considerably across pregnancy and provide predictive value for depressive symptoms in women, as well as poor foetal growth,” said Lisa M.
