摘要：Summary (Effects of social and environmental factors on neurocognitive performances of pre-school children
born premature or very low birth weight). - Severely preterm neonates (gestational age ≤ 32 weeks) and/or very
low birth weight (VLBW, with weight at birth ≤ 1500 g) are 2% of all newborns, with a rising incidence due to
the increase of multiple gestations and of pregnancies at advanced age. These neonates may be affected by
severe neurological pathologies (6-10% of cases), but they often have minor disabilities (such as distractibility,
hyperactivity, learning and social competence disabilities, deficit of motor development) difficult to be early
diagnosed, and frequently recognized only at pre-school or school age. A review of the current knowledge about
the effects of potential risk factors responsible for deficits of neurocognitive development in pre-school age and
for postnatal distress of mothers, and their inter-correlations, is reported.
