RESUMO
Exposure to drugs during pregnancy can result in neonatal abstinence syndrome (NAS), low birth weight, attention-deficit/hyperactivity disorder (ADHD), and behavioral issues, particularly during the school-age years. Recent research has expanded our understanding of the consequences of fentanyl exposure during pregnancy beyond the more commonly recognized effects, including respiratory complications, neurodevelopmental effects, increased risk of substance use disorders, gastrointestinal complications, cardiovascular effects, epigenetic changes, behavioral and emotional regulation disruptions, and long-term cognitive impairments. We present the case of a five-year-old female placed in foster care with a past medical history of asthma and a past psychiatric history of ADHD, oppositional defiant disorder (ODD), and disinhibited social engagement disorder. Her mother has a long history of substance use during pregnancy. From our interaction with the patient presented, we see that prenatal exposure to substances such as fentanyl and the disruption of attachment figures can have profound and lasting effects on a child's life, encompassing behavioral and cognitive aspects.
