What percentage of cerebral palsy cases in the 1980s were attributed to complications in childbirth?

1. Less than 5%

2. 10-15%

3. Less than 10%

4. More than 20%

The correct answer is: Less than 10%

The correct answer indicates that less than 10% of cerebral palsy cases in the 1980s were attributed to complications in childbirth. This statistic highlights a significant understanding within the field of neurology and obstetrics regarding the multifactorial nature of cerebral palsy. During that era, research identified that although complications during labor and delivery were recognized factors, they accounted for only a small fraction of total cases. The majority of cerebral palsy cases were later attributed to factors occurring during pregnancy, such as prenatal infections, genetic conditions, or brain development issues, rather than solely complications occurring at birth. This understanding has evolved over the years, emphasizing that while childbirth complications can be significant, they are not the predominant cause of cerebral palsy, which is influenced by a wide array of early life factors. Recognizing the importance of comprehensive prenatal care and monitoring has become crucial in reducing the risk of cerebral palsy and understanding its complex etiology.
