Applying Luria's diagnostic principles in the neuropsychological assessment of children

The first part of this article examines the theoretical justification for applying Luria's approach in the assessment of children. It is concluded that Luria's concepts of functional systems and the principle of specifying primary and secondary deficits may be applied to children. However, the selection of functional components to assess should be based on traditions of child neuropsychology rather than on Luria's assessment of adults. In addition, the tendency for comorbid disorders, mechanisms of neural adaptation to damage, and the prevalent types of brain abnormality in children render brain-behavior relationships more complex in children than in adults. The second part of the article describes how Luria's methods were adapted for use with children. An assessment, NEPSY, was developed by integrating Luria's views with contemporary child neuropsychological traditions. The NEPSY includes 27 homogeneous and psychometrically developed subtests, standardized in the United States and Finland for the age range of 3 to 12 years. The rationale of analyzing disorders of cognitive processes through a comprehensive and systematic assessment of their components, characteristic of Luria's approach, was preserved, but more specific principles of diagnosis were modified. Research findings obtained with a previously published, Finnish NEPSY version are presented.
