AGENESIS OF THE CORPUS CALLOSUM: An Electroencephalographic Study

AGENESIS OF THE CORPUS CALLOSUM: An Electroencephalographic Study Abstract SINCE the first demonstrations of the diagnostic potentialities of air studies of the ventricular system in patients with agenesis of the corpus callosum,1 an increasing number of cases of this condition have been recognized clinically. The existence of this entity in persons leading a relatively normal existence, as well as in patients with severe clinical signs and symptoms, has been noted,2 and the need of a functioning corpus callosum in the normal economy has therefore been questioned.

Abstract

Abstract SINCE the first demonstrations of the diagnostic potentialities of air studies of the ventricular system in patients with agenesis of the corpus callosum,1 an increasing number of cases of this condition have been recognized clinically. The existence of this entity in persons leading a relatively normal existence, as well as in patients with severe clinical signs and symptoms, has been noted,2 and the need of a functioning corpus callosum in the normal economy has therefore been questioned. Electroencephalography offers a method for study of such cases from a physiologic, as well as a diagnostic, standpoint, and the use of this method in conjunction with other, definitive technics may reveal a more complete picture of the activities of the corpus callosum in man. Publications on agenesis of the corpus callosum have rarely included electroencephalographic studies, hence this case, with a review of other reported cases, is presented. REPORT OF References 1.
