Prenatal exposure to valproate has been associated with an elevated risk (10%) for a broad range of congenital malformations including neural tube defects, as well as adverse neurodevelopmental sequelae, including lower IQ and developmental delays [...]
While we have data to support the use of antidepressants, including the selective serotonin reuptake inhibitors (SSRIs) and the serotonin norepinephrine reuptake inhibitors (SNRIs), during pregnancy, most studies have focused on risk of congenital [...]

We often talk about the importance of planning for pregnancy. In these discussions, we emphasize the importance of supplementation with folic acid as a means of decreasing risk for birth defects and improving neurodevelopmental [...]
We have long been interested in understanding the effects of prenatal exposure to antidepressants on the development of the fetal brain. Â The earliest studies addressing this question were small but yielded detailed (and reassuring) information [...]
Because breastfeeding has many psychological and medical benefits for both the mother and her child, many women would like to breastfeed. However, all medications taken by the mother are secreted into the breast milk. While various studies have addressed the short-term safety of antiepileptic drugs (AEDs) in nursing infants, none have systematically assessed the long-term effects of exposure to these drugs on cognitive development.
Two recent epidemiologic studies have demonstrated an association between prenatal exposure to selective serotonin reuptake inhibitor antidepressants (SSRIs) with autism spectrum disorders (ASD; Croen et al 2011, Rai et al, 2013). One important imitation of these two studies is that parental psychiatric disorder in itself is associated with an increased risk of ASD in the offspring, and these studies could not distinguish between the effects of drug exposure and the consequences of the underlying maternal psychiatric illness. Two new studies shed light on the association between prenatal antidepressant exposure and risk of autism spectrum disorder in the offspring.
It is estimated that autism spectrum disorders (ASD) affect about 1% to 2% of children. Research carried out in twins and families indicate that ASD is highly heritable; however, it is generally believed that while genetic factors play an important role, there is an interplay between genetic and environmental factors in the etiology of this disorder. Various environmental exposures have been implicated, including vaccinations, mercury, air pollution, insecticides, and infection.
While data accumulated over the last 30 years suggest that certain antidepressants may be used with relative safety during pregnancy, our knowledge regarding the risks of prenatal exposure to psychotropic medications is incomplete. Because neuronal migration and differentiation occur throughout pregnancy and into the early years of life, development of the central nervous system (CNS) remains particularly vulnerable throughout pregnancy.
While we have data on the use of lithium use during pregnancy with regard to risk for congenital malformations, there is much less information on the long-term effects of lithium on neurodevelopment. A recent study from the Perinatal Center of the Leiden University Medical Center provides some reassuring data on the long-term effects of lithium exposure.
