Magnetic resonance imaging study of the brain in autism

摘要: Autism is a neuropsychiatric disorder of social, cognitive, and language development. Cerebellar abnormality in autism has been shown consistently from autopsy magnetic resonance image (MRI) studies. A new MRI study with careful methodologic designs identified two subgroups autistic patients: hypoplasia hyperplasia cerebellar vermian lobules VI-VII. The existence these subtypes was also supported via the meta-analysis data separate research groups. In addition to abnormality, recent studies demonstrated abnormalities parietal lobe posterior subregions corpus callosum where cortical fibers are concentrated. Furthermore, neurobehavioral correlates have investigated. contrast, there lack significant difference cross-sectional size hippocampal formation between normal subjects, which discrepant predictions based on some
