[Significant neuropsychological impairment in children with normal MRI results].

The aim of the present work was to present significant cognitive impairment in 7 children with normal neuroimaging and electroencefalography results. In 6 children we observed difficulties in verbal auditory learning, in 3 visual memory impairment, and in 1 a disorder of visuo-spatial analysis and synthesis abilities. The clinical examinations performed during the diagnostic process (MRI, CT, Eeg) revealed no neurobiological correlates of the observed neuropsychological impairment. The authors used the cases described to remind, that even though current neuroimaging techniques seem excitingly promising in the diagnostic process, psychological and neuropsychological assessment remains the most sensitive method for the measurment and description of cognitive functions.
