Autistic Regression in Relation to Limbic Pathology and Epilepsy: Report of Two Cases

Abstract: SUMMARY The authors repbrt a follow‐up study of two boys who presented with autistic regression (after normal early development) at 13 and 22 months. Both were found on cerebral imaging to have tuberous sclerosis, with lesions involving the limbic system, bilaterally in the second child. The first child's regression coincided with the onset of partial complex seizures; disappearance of the autistic behaviour and marked improvement in cognitive development occurred with remission of the epilepsy. The second chi… Show more

“…Clinically, children and adults with autism or another ASD have been reported to have abnormalities affecting the medial temporal lobe structures, such as enlargement of the temporal horn of the lateral ventricles (Campbell et al, 1982;Damasio et al, 1980;Hauser et al, 1975;Jacobson et al, 1988), and temporal lobe epilepsy or temporal EEG abnormalities (DeLong, 1978;Deonna et al, 1993;Deykin and MacMahon, 1979;Hauser et al, 1975;Payton and Minshew, 1987). In addition, Hoon and Reiss (1992) described a young male child with a left temporal oligodendroglioma, who demonstrated a constellation of autistic behaviors meeting the DSM-III-R criteria for pervasive developmental disorder.…”

“…Deonna et al (1993), for example, described two children with tuberous sclerosis whose language and psychosocial development was adequate until 18 and 22 months of age. With the onset of seizures, both children demonstrated a loss of language and deterioration in behavior characterized by poor social interactions, hyperactivity, obsessive-compulsive tendencies, stereotypies, and a decrease in symbolic play.…”

“…Other studies report that up to 65% of cases with autism or 'autistic features' may manifest abnormal spikes in one or both temporal lobes, although much more research needs to be undertaken in identification of the brain circuitry involved in semantic and pragmatic processing of language before a definitive understanding of the neurological basis of these impairments may be understood in the context of autism [89]. Whether the association between severe language and social impairments may lead one to conclude that the cause of the pragmatic and accompanying language difficulties lies within the temporal lobes in this instance or whether it merely contributes to the overall language dysfunction associated with autism as a distinct entity is, however, a matter for conjecture [91,92] (see Table V).…”
