Closing in on risk factors for cerebral palsy and infant death

A recent study published in Obstetrics & Gynecology found that birth defects and poor fetal growth are the most common risk factors for cerebral palsy and infant death. The research suggests that these risk factors, rather than asphyxial birth events, may contribute to the development of cerebral palsy and infant mortality.
