[Cognitive functions in agenesis of the corpus callosum].

Four patients with agenesis of the corpus callosum diagnosed through neuroradiologic tests has been studied, from the upper cerebral functions point of view. Three had consulted because of seizure, and the other because of cerebellar hemorrhage. Multiple fields of the cognitive functions were examined and the presence of an interhemispheric disconnection syndrome was investigated. All tests were absolutely normal in the four patients. We discuss clinical and radiologic aspects as well as other associated malformations.
