Cerebral palsy classifications hinge on when the brain injury occurs. If the injury happens before birth or around the time of birth, the resulting CP is considered congenital. If the brain injury happens after birth, due to events like infection, head trauma, or hypoxic-ischemic events later in infancy, the CP is acquired. Therefore, the statement that congenital CP occurs at or before birth correctly identifies the timing that differentiates congenital from acquired CP. The idea that acquired CP occurs before birth is incorrect, and CP is not the same condition in all cases—the distinction rests on when the brain injury occurs, with congenital CP tied to prenatal or perinatal events and acquired CP to postnatal injuries. Congenital CP is not exclusively due to infection, as multiple prenatal and perinatal factors can contribute.
