Objective: To establish in a prospective study whether a characteristic neuropsychological profile exists in ex-preterm children who do not exhibit neurodevelopmental deficits on routine clinical examination. Methods: Thirty intellectually normal children born preterm (30- 34 weeks gestation) without major neurological disabilities and a control group of term children matched for age, sex, and parental educational and occupational status were assessed at 3- 4 years of age to obtain a complete neuropsychological profile. Intellectual ability, language comprehension and expression, perceptual and visual motor function, working memory, and attention and behavioural problems were investigated. Results: Even in the absence of major neurological signs, children born preterm achieved lower mean scores than controls on the Stanford- Binet intelligence scale (110.8 v 121, p < 0.001 ), visual perception test (33.8 v 42.7, P< 0.001 ), visual motor integration test (42.6 v 47.4, P=0.049), memory for location test (8.4 v 9.5,P= 0.007), sustained attention test (41.6 v 51.5,P= 0.009), and the picture vocabulary test (33.3 v 44.7, P = 0.021). Conclusions: Neuropsychological abnormalities can be detected early in childhood in apparently normal ex-preterm children and are consistent with a growing body of evidence that prematurity may be associated with long term neuropsychological morbidity in childhood and adolescence. | Caravale B.
