Research Description

Current research indicates that prenatal exposure to phthalates, a ubiquitous endocrine disruptor, is associated with adverse outcomes. However, the effects of exposure to phthalates and additional compounds like acetaminophen, over the counter (OTC) pain medication, during prenatal period are unknown. Current research establishes that prenatal exposure to acetaminophen has anti-androgenic effects in both animal models and children and alters many of the same neurodevelopmental outcomes affected by phthalate exposure. Some of these neurodevelopmental pathways play a crucial role in social cognition and language development, aspects of behavior used in the diagnosis of autism. I examine the potential interaction of prenatal exposure to acetaminophen and phthalates on social cognition in a novel paradigm for 7.5-month-old infants; a validated measure of social cognition at 2-3 years; and language development.
