Fetus can sense how Mom's doing psychologically
Science has learned that a developing fetus receives messages from the mother, everything from hearing mom's heartbeat to the music she might direct toward her belly. But a new study in the journal Psychological Science suggests that the fetus can pick up on signals and respond to a mother experiencing depression.
Researchers at the University of California-Irvine recruited pregnant women and checked them for depression before and after the mothers delivered their babies. They also tested the babies after delivery to see how their development was progressing.
What appeared to matter most, according to their finding, was a consistent environment. The babies who fared best were those born to mothers who were either not depressed both before and after birth, or those who were depressed both before and afterwards. When mothers' moods shifted from to depression to healthy or from healthy to depression, the change appeared to slow development of their babies.
Authors said the finding should not be taken as an indication that depressed mothers should be left that way during pregnancy, but rather that they should be treated when they first show signs of depression.
"We believe the human fetus is an active participant in its own development and is collecting information for life after birth," said Curt A. Sandman, one of the authors and an emeritus professor of psychiatry and human behavior at UC-Irvine. "It's preparing for life based on messages the mom is providing."
