Scientific studies are investigating how premature birth affects neurological and cognitive maturation. Research led by Panagiotis Kratimenos, involving George Washington University and Children’s National Hospital, suggests that preterm birth disrupts the development of the cerebellum. This disruption may explain why infants face challenges with speech, movement, and learning even when imaging shows no visible damage, as the cerebellum undergoes rapid growth during the final weeks of pregnancy. A study published in the journal Science further details that preterm birth interrupts a critical phase of cellular and genetic development. Because the cerebellum undergoes rapid growth and neuron organization between the 24th and 40th weeks of gestation, premature birth causes much of this process to occur outside the womb. This can lead to the incomplete maturation of certain cell populations. Since the cerebellum serves as a control center for physical movement, cognitive functions, emotions, and IQ, these cellular changes may have long-term developmental implications. Additional research from Finland, published in JAMA Network Open, examined long term cognitive outcomes in a large cohort. This study found that individuals born between the 34th and 36th weeks of gestation exhibited cognitive abilities in adulthood similar to those born at full term. The findings indicate that while very premature births are linked to more significant differences, gestational age and birth weight are complex factors in determining future intelligence.
