Cognitive functioning in children with typical cri du chat (5p-) syndrome.
This study is the first attempt to assess systematically the cognitive functioning in children diagnosed with typical cri du chat syndrome (CDCS) using neuropsychological test measures. Twenty-six children aged between 6 years 4 months and 15 years 5 months (mean 8 years 3 months) completed a battery of tasks measuring IQ level, receptive and expressive language skills, and articulation. Twenty-four children were in the severe learning-disability range with no specific verbal or performance profile. Using more finely tuned measures of cognition, however, a clear discrepancy in the pattern of language functioning was found with better receptive than expressive language skills. One implication of these findings is that parents and professionals should be more optimistic about the capacities of children with CDCS to understand more complex verbal commands than their expressive language skills would suggest.
