What is the most common cause of cerebral palsy?

• A. It results when the cord gets wrapped around the neck in the birth canal.
• B. It is the result of a forceps delivery.
• C. It is the result of a premature birth or very low birth weight.
• D. It is the result of preeclampsia in the mother.

Answer: (C)

Cerebral palsy results from a brain injury or abnormal brain development that occurs around birth or in early infancy, leading to persistent movement and posture problems. The most common risk factor is prematurity and very low birth weight. When babies are born premature, their brains are especially vulnerable to injury from factors like limited blood flow, inflammation, or small bleeds, which can disrupt the development of motor pathways—particularly in the periventricular white matter. This pattern explains why CP is more common among preterm, very low birth weight infants. While cord compression, delivery instrument use, or maternal conditions like preeclampsia can contribute to birth complications, they are not the predominant drivers of CP. Prematurity and low birth weight consistently emerge as the strongest associated factors.
