Experience of early-life pain in premature infants is associated with atypical cerebellar development and later neurodevelopmental deficits.

Background: Infants born very and extremely premature (V/EPT) are at a significantly elevated risk for neurodevelopmental disorders and delays even in the absence of structural brain injuries. These risks may be due to earlier-than-typical exposure to the extrauterine environment, and its bright lights, loud noises, and exposures to painful procedures. Given the relative underdeveloped pain modulatory responses in these infants, frequent pain exposures may confer risk for later deficits.

Impaired in vivo feto-placental development is associated with neonatal neurobehavioral outcomes.

Background: Fetal growth restriction (FGR) is a risk factor for neurodevelopmental problems, yet remains poorly understood. We sought to examine the relationship between intrauterine development and neonatal neurobehavior in pregnancies diagnosed with antenatal FGR.

Methods: We recruited women with singleton pregnancies diagnosed with FGR and measured placental and fetal brain volumes using MRI.
