Perceptual-motor, visual and cognitive ability in very low birthweight preschool children without neonatal ultrasound abnormalities.

Thirty-six children born preterm with very low birth weight without neonatal brain disorders and normal cerebral ultrasound findings were examined at pre-school age: visual, perceptual motor, attention, behaviour and cognitive assessments were performed in the study group as well as in a control group of term children matched for age, sex and parental educational and occupational status. The results showed a significant lower scoring in perceptual motor skills in the study group, associated with a defect of accuracy in spatial attention and a higher incidence of stereopsis impairment related with perceptual motor disabilities. Behavioural disorders, in terms of emotional maturation and hyperactivity, were significantly more frequent in the study group. To prevent behavioural and learning problems at school, a complete longitudinal assessment including visual functions and perceptual motor abilities seems mandatory in preterm born children, even in the absence of neonatal brain disorders including abnormal cerebral ultrasound findings.
