Recent research from the National Institutes of Health brings important news for families of extremely premature babies. A major study tracking nearly 7,000 children across the United States found that cerebral palsy diagnoses are rising among infants born before 27 weeks of pregnancy. While this might initially sound concerning, the findings actually reflect significant progress in neonatal care.

A Look at the Study

The research, conducted by Sara B. DeMauro, M.D., at the Children’s Hospital of Philadelphia and colleagues at the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network, tracked children at 25 academic research centers nationwide from 2008 to 2019. The study focused specifically on babies born before 27 weeks of pregnancy, a group considered extremely preterm. Researchers evaluated these children when they reached 18 to 26 months of age, corrected for prematurity.

The scope of this research is significant. With data from centers across the country and a diverse population that reflects national demographics, the findings give us a clear picture of trends in cerebral palsy rates among extremely preterm infants.

The Numbers Tell a Story

Of the 6,927 children included in the study, 1,303 (18.8%) were diagnosed with cerebral palsy. From 2008 through 2019, the odds of cerebral palsy in this population increased by an average of 11% per year.

The research findings also revealed that an additional 1,125 children (16.2%) had suspected motor abnormalities, 481 (6.9%) had hypotonia (low muscle tone), and 301 (4.3%) had other abnormal neurologic findings. Just 3,717 children (53.7%) showed normal neurological examinations and normal neurologic function.

Understanding Severity Levels

The research didn’t just count cases of cerebral palsy. It also looked at how severely the condition affected these children. The results offer some encouraging news. Among children diagnosed with cerebral palsy, 64% had level I, which is the least severe form. These children typically have relatively minor movement challenges.

About 22% had level II or III cerebral palsy, representing moderate involvement, while 14% had level IV or V cerebral palsy, the most severe forms.

Why Are Numbers Increasing?

Here’s where the news becomes more positive than it might initially appear. The researchers believe that improvements in medical care are allowing more extremely premature infants to survive, including those who face the highest risk for cerebral palsy.

Think about it this way. Decades ago, many babies born this early simply didn’t survive. As neonatal intensive care has advanced dramatically, more of these vulnerable infants are making it through those critical early weeks and months. Some of these survivors face neurological challenges like cerebral palsy, but they’re alive and able to receive treatment and support.

Improved diagnosis of cerebral palsy over time may also help explain the findings, according to the NIH study.

Additional Risk Factors Identified

The study also identified several health complications that increased the risk of cerebral palsy in extremely preterm infants. Higher risk was associated with lower birth weight, late onset sepsis (a blood infection occurring after delivery), higher grades of intraventricular hemorrhage (bleeding in the ventricles, or cavities, in the brain), periventricular leukomalacia (death of small areas of the brain surrounding the ventricles), and grade 3 bronchopulmonary dysplasia (lung disease of prematurity that required a ventilator at 36 weeks postmenstrual age).

Understanding these risk factors helps medical teams identify which babies need the closest monitoring and earliest intervention.

Better Diagnosis May Play a Role

Another factor that might explain some of the increase is improved diagnosis of cerebral palsy itself. Cerebral palsy isn’t identified through a single test. Instead, doctors monitor children’s development over time, watching for delays and movement difficulties.

As our understanding of cerebral palsy has grown, healthcare providers have become better at recognizing signs of the condition, particularly milder forms that might have been missed in the past. Earlier and more accurate diagnosis means children can start receiving therapies and interventions sooner.

What This Means for Families

If you’re the parent of an extremely premature baby, these statistics might feel overwhelming. It’s important to remember that this research reflects broad population trends, not individual outcomes. Many extremely preterm babies develop typically, and even among those diagnosed with cerebral palsy, the majority have milder forms of the condition.

The study also highlights how far neonatal medicine has come. According to the research analysis, cerebral palsy is estimated to occur in up to 0.3% of all births, but is 70 times more common among infants weighing less than 3.3 pounds at birth. Babies who wouldn’t have survived 20 or 30 years ago are not only living, but many are thriving.

The Value of Early Monitoring

These findings underscore the importance of careful developmental monitoring for extremely preterm infants. Regular check-ups that assess motor skills, muscle tone, and developmental milestones allow for early identification of potential issues.

When cerebral palsy is identified early, intervention can begin immediately. Physical therapy, occupational therapy, and other treatments work best when started young, taking advantage of the brain’s remarkable ability to form new connections and adapt during early childhood.

Looking Forward

The researchers who conducted the NIH study emphasized the need for additional studies of children with cerebral palsy as they age. Understanding long-term outcomes will help guide treatment approaches and provide families with realistic expectations about their child’s future.

Research continues into preventing preterm birth and minimizing complications when early delivery is unavoidable. Scientists are also working to understand which interventions most effectively support extremely premature babies during those critical first weeks of life.
