title: Neurological and psychological development of low-risk preterm infants in the first year of life.
abstract: Twenty-four selected low-risk preterm and 10 full-term infants were followed in a prospective study of the evolution of neurological signs in the first year of life and to consider the prognostic value of transient neurological abnormalities in relation to learning disabilities at school age. We report the results of the assessments made during the first 12 months. The assessment at 3, 6, 9 and 12 months was made using the Amiel-Tison neurological schedule and the Griffiths developmental scale. A high percentage of our low-risk premature infants (69% of 37-34 weeks gestational age and 75% of 33-27 weeks gestational age group) showed transient neurological anomalies, whereas no major neurological sequelae, i.e., cerebral palsies or mental impairment, were found. Moreover, in our series, the syndrome of transient dystonia associated with low birth weight, already described by other authors in samples not selected for risk, was not observed. The psychological development of all our infants was within normal limits at every assessment. Nevertheless, a significantly decreased performance at the sixth month in both preterm groups, particularly in the group of low gestational age, was found, and its significance will be clarified by further follow-up studies of early school age.
