    Abstract:
    OBJECTIVES: The study aimed to investigate whether maternal GAD during pregnancy affects fetal circulating brain-derived neurotrophic factor (BDNF), which plays important roles in neuronal development, by comparing cord blood BDNF levels in newborn infants of women with and without GAD. METHODS: Study sample included 19 women with GAD and 25 women without any psychiatric disorder. GAD and other psychiatric diagnoses were screened by means of the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. The blood sample for the determination of BDNF level was obtained from the umbilical cord during delivery. RESULTS: Cord blood BDNF levels in newborn infants of healthy women were approximately two-fold compared to newborn infants of women with GAD, and the difference was statistically significant. The duration of GAD during pregnancy was the only variable correlating with cord blood BDNF levels. CONCLUSIONS: The study results imply that prolonged maternal GAD during pregnancy may negatively influence neurodevelopment of the fetus through lower levels of circulating BDNF.
