Abstract

Utilizing Computerized Brain Tomography, Left-Right Morphologic Asymmetries of the Parietooccipital Region Were Judged in 16 Autistic Patients, 44 Mentally Retarded Patients, and 100 Miscellaneous Neurological Patients. in 57% of the Autistic Patients the Right Parietooccipital Region Was Wider Than the Left, While This Pattern of Cerebral Asymmetry Was Found in Only 23% of the Mentally Retarded Patients and 25% of the Neurological Patients. It is Suggested that Unfavorable Morphologic Asymmetries of the Brain Near the Posterior Language Zone May Contribute to the Difficulties Autistic Children Experience in Acquiring Language. © 1979 Plenum Publishing Corporation.
