Neurological outcomes following preterm birth

Area of Science:

• Neonatal neurology
• Pediatric neurodevelopment
• Developmental disabilities

Background:

• Neonatal survival rates have improved, raising concerns about associated neurodevelopmental morbidity.
• Historically, neuromotor impairments like cerebral palsy were thought to increase with improved survival.
• Recent data indicate a potential decline in cerebral palsy rates, except for extremely premature infants.

Purpose of the Study:

• To review current evidence on neurodevelopmental outcomes in neonates.
• To highlight the evolving understanding of neuromotor morbidity and its impact.
• To discuss advancements in outcome measurement and neuro-imaging for neonatal brain injury.

Main Methods:

• Review of recent evidence on neuromotor and neurosensory impairments in neonates.
• Discussion of validated motor and manual function classification systems for cerebral palsy.
• Exploration of advanced neuro-imaging techniques like volumetric MRI.

Main Results:

• Neuromotor morbidity, specifically cerebral palsy, may be decreasing for most neonates.
• Severe sensory impairments remain static, while mild motor problems are increasingly recognized.
• These motor issues correlate with developmental coordination disorder, executive dysfunction, and reduced school performance.

Conclusions:

• While severe impairments are stable, subtle motor deficits and associated neurodevelopmental issues require attention.
• Standardized classification systems and advanced neuro-imaging are crucial for understanding neonatal brain injury and developmental trajectories.
• Further research into composite motor assessments and longitudinal studies is needed.
