Researchers are just beginning to learn about the influence of depression on the growing fetus and the mother. Recent research suggests that this illness exponentially increases at the onset of menses with hormonal changes correlating with the onset of major depressive disorder. We also know that throughout the women’s lifecycle, increased rates of depression occur during periods of hormonal flux. One of these period is depression during pregnancy. Over the past decade, interest in the prenatal period has increased and is part of a broader spectrum of women’s mental health.
