[Neurologic pathology in the neonatal period: relation to birth weight and gestational age].
Six Italian university centers have taken part in the Perinatal Preventive Medicine Project of the National Research Council since 1973. In this report the preliminary data on neonatal neurological disorders of 38775 single not malformed infants are presented. Neurological abnormality has been defined by the presence of at least one of the following symptoms: seizures, hypertonia, hypotonia, apneic spells. The relative frequencies of seizures vary from a minimum of 0.28% to a maximum of 0.75% in the six centers. The frequencies of the other symptoms demonstrate a greater variability among centers. Males are more affected than females. The relative frequency of neurological abnormalities is higher among babies with low birthweight, short gestational age or retarded intrauterine growth. Also, the frequency of seizures is higher among babies with low birthweight or retarded intrauterine growth while the relationship between seizures and gestational age is not clear.
