title: [Alterations in neuro-development in the 1st year of life in newborn infants weighing 2000 grams or less at birth].
abstract: The infants with low weight at birth have great chance of exhibiting early death or neurodevelopmental sequelae. We prospectively evaluated the neurological and psychological development during the first year of life in 118 infants who weighted less than 2,000 g at birth. All patients were examined with the Amiel Tison and Grenier test (neurologic evaluation), Gesell test (psychological) and Brunette-Lezine test (Psychomotor scale). Mean gestational age was 33 weeks (SD = 3.1) and birth mean weight was 1495 g (SD = 291). Seventy per cent were delivered by cesarean section. Neurological abnormalities were found in 20 infants (alteration of muscular tone in all and motor deficit in 50%). Twenty five per cent had abnormal Gesell test and 17% psychomotor retardation (13% mild and 4% severe).
