Prenatal opioid exposure is associated with delayed locomotor performance at multiple stages of early child development1,2 and with smaller neuroanatomical structures, such as the basal ganglia.3 The motor cortex, which controls speech and motor skills, may also be vulnerable to drug exposure, but to our knowledge, this has yet to be assessed. Identifying risks of exposure associated with brain structures is critical for prevention and intervention strategies for cognitive effects that can last long after conception.3,4
