Analysis of visuospatial abilities in chiari malformation Type I

Abstract: The involvement of the cerebellum in visuospatial abilities has been evidenced in numerous studies, based on the cerebellar-cortical circuitry. This domain has been evaluated in several patients with cerebellar disorders, but the assessment of visuospatial processing in Chiari malformation type I (CM-I) is scarce. The aim of this study is to analyze the visuospatial performance between CM-I adult patients and healthy controls. Participants have been tested using Block Design and Visual Puzzles subtests of the Wechsler Adult Intelligence Scale (WAIS), the Benton Judgment of Line Orientation test, and the Rey-Osterrieth Complex Figure test. The anxious-depressive symptomatology, the physical pain, and the premorbid intelligence have been controlled for, as well. The CM-I patients showed a significantly lower performance; however, after analyzing and controlling for the effect of clinical variables and psychopathological symptomatology, the main effect was maintained for visual puzzles and line orientation tasks. The findings suggest that CM-I patients show a poorer performance in tasks that require an exercise of perceptual reasoning without motor demand, accompanied by visualization and mental imagery of the stimuli. This study contributes towards the reinforcement of the evidence on the cognitive alterations associated to CM-I.
