Brain structure and neurocognitive and behavioural function in adolescents who were born very preterm

105 infants born before 33 weeks of gestation in 1979-80 had ultrasonographic scans and were examined at 1, 4, and 8 years. At age 14-15 years, 72 of those who remained in UK and 21 controls underwent brain magnetic resonance imaging, as well as neurological, cognitive, and behavioural assesment. Individuals born very preterm show an excess of neurocognitive and behavioural problems in adolescence, and more than half have abnormal MRI brain
