This observational study aims to early identify, through a rigorous and standardized follow-up, infants at high risk for Cerebral Palsy. After the consent agreement firmed by the parents, infants born at term or preterm with ultrasonographic evidence of brain injury considered at risk for neurodevelopmental disorders will be strictly monitored during the first months of life performing a periodic neurological assessment (Prechtl's General Movement (GMA) and the Hammersmith Infant Neurological Examination) at term age and around 3 months of post term age. Moreover, to study more accurately the brain injury early identified by ultrasonographic brain exam, around 6 weeks of post-term age the enrolled infants will perform, as recommended in infants at risk, brain Magnetic Resonance (RM).
