Analysis of visuospatial activity in preschool children with attention deficit disorder

Parameters of visuospatial components of mental activity were studied in Mexican children aged 5–6 years with attention deficit disorder. The control group (norm) consisted of preschool children of the same age who attended municipal kindergartens. Neuropsychological methods specially developed and adapted for Mexican children were used. The results testified to prominent impairments of the parameters of spatial analysis and synthesis and of the formation level of object imagery, suggesting functional weakness of the posterior associative (TPO) cortical areas of both hemispheres. The results elucidate specific difficulties in cognitive activity and other impairments in children with attention deficit disorder.
