Pneumographic findings in the infantile autism syndrome. A correlation with temporal lobe disease
Insights
Pneumoencephalography revealed enlarged left temporal horns in children with autism and language delays. This suggests medial temporal lobe dysfunction may contribute to infantile autism.
Area of Science:
- Neuroscience
- Developmental Psychology
- Pediatric Neurology
Background:
- Investigating the neurobiological underpinnings of infantile autism.
- Examining children with developmental delays and autistic behaviors without other neurological diagnoses.
Observation:
- Pneumoencephalography (PEG) was performed on 18 children with retarded language development and autistic behavior.
- No specific neurological diseases or gross motor disorders were identified in the study group.
Findings:
- Pathological enlargement of the left temporal horn was observed in 15 out of 18 children.
- Enlargement of both temporal horns or mild lateral ventricular enlargement, particularly on the left, was noted in some cases.
- Findings were compared to temporal lobe disease patterns, including Korsakoff and Kluver-Bucy syndromes.
Implications:
- Suggests medial temporal lobe dysfunction as a potential key factor in the pathogenesis of infantile autism.
- Highlights the role of specific brain structures in the development of autistic behaviors.
- Warrants further investigation into the neuroanatomy of autism spectrum disorder.
Abstract:
Pneumoencephalographic findings are described in a group of 18 children who presented to us with a history of retarded language development and autistic behaviour disturbances. None had specific diagnosable neurological diseases nor gross motor disorders. PEG findings included, most prominently, pathological enlargement of the left temporal horn in 15 cases; some cases showed enlargement of both temporal horns or mild variable enlargement of the lateral ventricles, especially the left. Comparisons between infantile autism and recognized patterns of temporal lobe disease (especially Korsakoff syndrome and Kluver-Bucy syndrome) are drawn. We have suggested that medial temporal lobe dysfunction may be a major factor in the pathogenesis of the syndrome of infantile autism.
