Under normal circumstances, not all preterm infants will develop cerebral palsy. Preterm babies are more susceptible due to their immature organ systems compared to full-term babies. If they face poor adaptation to the environment during or after childbirth, it can increase the likelihood of developing cerebral palsy. However, this does not mean that cerebral palsy will occur in all cases. Furthermore, since the brain development system is not fully mature in preterm infants, conditions such as brain hypoxia may occur, which can affect the brain and contribute to the development of cerebral palsy.
