• The mental development and neurologic outcome of four sets of preterm twins, In whom one infant within each pair developed posthemorrhagic hydrocephalus during the neonatal period, were assessed. Each hydrocephalic infant presented with signs of increased intracranial pressure and required placement of a ventriculoperitoneal shunt. Three of the four hydrocephalic infants required revision or replacement of the shunt during the first year. The four nonhydrocephalic infants had normal neurologic outcomes. All four hydrocephalic infants had some neurologic abnormalities on follow-up examination. Neurologic abnormalities were transient in one infant and persistent in three others, each of whom showed evidence of mild right hemiparesis. Within each twin pair, developmental rates and mental test scores were strikingly similar throughout infancy and early childhood. Two of the twin pairs have undergone psychological assessments at 8 and 11 years of age. Relatively lower IQ scores were obtained for the hydrocephalic child in each twin pair at these ages.
