While we have considerable information regarding the teratogenic risk associated with prenatal exposure to various antiepileptic drugs (AEDs), we have considerably less information on the impact of exposure to AEDs on behavioral outcomes in [...]
It is fairly well-known that interactions between parents and children are associated with improved developmental outcomes in children. Previous research has primarily focused on how maternal rather than paternal involvement influences infant neurodevelopment. A recent [...]
While some women with bipolar disorder elect to discontinue their psychotropic medications during pregnancy to mitigate fetal exposure, Viguera and colleagues (2000, 2007) found that women stabilized on lithium face a significant risk for [...]
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.
During fetal life, neurons proliferate, migrate and form connections, providing the structure of the developing brain. Neurons reach their final destinations by the 16th week of gestation, while branching and making appropriate connections occur even before that time (1). The brain continues to develop during the entire pregnancy, with most of the synapse formation in the developing brain happens during the third trimester (2).
