Forebrain structure in infantile autism.
Researchers implicate central nervous system dysfunction in infantile autism, but postmortem examinations and in vivo brain imaging studies have produced conflicting results concerning the neuronal systems involved. Magnetic resonance imaging--a new modality of in vivo brain imaging--was used to investigate the cerebral and thalamic structure of 105 autistic patients. Compared with the control group, there was an overall difference in the forebrain morphology of the autistic subjects due to subtle but statistically significant differences in the anterior ventricular horns, lateral ventricles, and the right lenticular nucleus. These results, when considered with previous studies of cerebral structure, suggest that there are subtle alterations in the forebrain of autistic patients.
