Human studies Pregnancy is associated with an increased risk for mood and anxiety episodes. The fraction of pregnant women that present the diagnostic criteria for major depression ranges from 7% to 26%62,63 and about 40% of patients with a history of major depression relapse during pregnancy.64 Given the deleterious effects of maternal depression on fetal Inhibitors,research,lifescience,medical development, an increasing fraction of woman (up to 13% of pregnant women in some studies) are treated with antidepressants during pregnancy.62,65 Unfortunately, SSRIs cross the placenta49,66 and have been shown to impact the

developing fetus.63,67 Ultrasonographic observations of fetuses throughout gestation revealed that exposure to SSRIs altered the emergence of quiet nonrapid eye movement sleep during the last trimester and decreased the inhibitory motor control during this sleep phase.68 Furthermore, exposure to SSRIs reduced fetal middle cerebral artery blood flow as well as fetal heart rate variability.69 Exposure to SSRIs during pregnancy Inhibitors,research,lifescience,medical is associated with lower APGAR scores, with poor neonatal adjustment, increased

risk for neonatal respiratory distress, jaundice, feeding problems,62,70-74 delayed head growth,75 pulmonary hypertension, and preterm birth.70,75,76 Newborns exposed to SSRIs during Inhibitors,research,lifescience,medical late gestation more frequently display symptoms such as myoclonus, restlessness, tremor, hyperreflexia, Inhibitors,research,lifescience,medical shivering, and rigidity.73 Neonatal symptoms were usually mild and disappeared within 2 weeks of age.77 Adverse neonatal outcomes were generally attributed to a withdrawal or a toxicity effect from SSRI exposure. However, a recent study indicates that infants exposed to

SSRIs during gestation, but for whom the drug was stopped 14 days before delivery, still displayed an increased Inhibitors,research,lifescience,medical risk for adverse neonatal outcomes, suggesting that exposure to SSRIs during late gestation resulted in more enduring effects.78 At later developmental time points, gestational SSRI exposure was associated with blunted pain reactivity,79 a slight delay in motor development,71,74 and increased internalizing behaviors.80 More worrisome IWP-2 datasheet findings come from two recent studies showing that antidepressant exposure may increase the risk for autism spectrum disorder81,82; however, it should be noted that in retrospective studies that examined the long-term effects of SSRI exposure it is often difficult oxyclozanide to control for the severity of maternal depression and associated psychiatric comorbidities. Thus, some of the developmental consequences attributed to SSRI exposure could be due to the effects of increased maternal stress in the context of complex psychiatric psychopathology. Serotonin and stressor controllability Stress acts across different developmental time periods and can have a profound impact on the functional maturation of different sets of neural circuits.
