[Cognitive and neuropsychological profiles in malformation syndromes: a comparison between Down's syndrome and Williams' syndrome within a follow-up].

The present work compares the neuropsychological and cognitive profiles of 4 children with the Williams and Down syndrome. The Authors stress the importance of an accurate analysis of each child's developmental story. They monitor children with physical malformations associated to Mental Retardation or other psychopathological problems in order to have a better understanding of their cognitive strategies and true potential and of their social and emotional implications. This procedure allows immediate action to be taken as soon as physical, emotional or cognitive problems arise. It also enables parents to be fully aware of their children's problems and to be able to meet their different developmental needs.
