Perinatal Brain Injury: Predicting Outcomes

Perinatal Brain Injury: Predicting Outcomes

Posted By Scarlett Law Group || 31-Oct-2011

Neonatal encephalopathy, or disturbed neurological functioning in a term infant, affects between 1 and 7 babies out of 1000 live births. It causes permanent disability in terms of cognitive and motor development in 15-20% of affected newborns. An MRI scan can help predict outcomes for infants with brain injury, with increasing levels of accuracy.

A recent study found that:

  • The presence of brainstem lesions is predictive of mortality. Close to half of infants with these lesions die within the first three years of life.
  • Mesencephalic and pontine lesions, alone or in combination, are also associated with high rates of mortality.
  • The severity of damage to basal ganglia and thalamus (BGT) is predictive of motor impairment, with 89% accuracy.
  • BGT is closely associated with cerebral palsy (CP)-the worse the BGT injury, the higher the risk of CP. Infants with severe BGT injuries have near universal rates of CP.
  • Damage to the white matter, cortex, and brainstem is not associated with motor impairment.

Further study of these associations shows promise in improving outcomes.
