One hundred preterm children with periventricular leukomalacia evident on brain magnetic resonance imaging and who had undergone neuropsychologic evaluation were selected. Intellectual disability was noted in 27.8% of the children with mild periventricular leukomalacia, 53.2% with moderate periventricular leukomalacia, and 77.1% with severe periventricular leukomalacia. The rates of major neurodevelopmental impairments such as cerebral palsy or intellectual disability were related to the severity of periventricular leukomalacia but not to gestational age or epilepsy. There were significant differences in the intelligence quotient (IQ) and social maturity quotient between 3 groups of periventricular leukomalacia. The performance IQ was significantly lower than the verbal IQ. Behavioral problems were noted in about one-third of the children but the rate was not related with the severity of periventricular leukomalacia. Our study revealed the significant associations between severity of periventricular leukomalacia and cognitive and social adaptive functions in the preterm children.<\/jats:p>","DOI":"10.1177\/0883073815604229","type":"journal-article","created":{"date-parts":[[2015,9,18]],"date-time":"2015-09-18T22:04:48Z","timestamp":1442613888000},"page":"603-612","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":40,"title":["The
