Brief Report: Sensorimotor Gating in Idiopathic Autism and Autism Associated with Fragile X Syndrome / Jennifer YUHAS in Journal of Autism and Developmental Disorders, 41-2 (February 2011)

Titre : Brief Report: Sensorimotor Gating in Idiopathic Autism and Autism Associated with Fragile X Syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Jennifer YUHAS, Auteur ; Lisa CORDEIRO, Auteur ; Flora TASSONE, Auteur ; Elizabeth C. BALLINGER, Auteur ; Andrea SCHNEIDER, Auteur ; James M. LONG, Auteur ; Edward M. ORNITZ, Auteur ; David HESSL, Auteur Année de publication : 2011 Article en page(s) : p.248-253 Note générale : Article Open Access Langues : Anglais (eng) Mots-clés : PPI FMR1 gene Sensorimotor gating mGluR5 Prepulse inhibition Startle Index. décimale : PER Périodiques Résumé : Prepulse inhibition (PPI) may useful for exploring the proposed shared neurobiology between idiopathic autism and autism caused by FXS. We compared PPI in four groups: typically developing controls (n = 18), FXS and autism (FXS+A; n = 15), FXS without autism spectrum disorder (FXS−A; n = 17), and idiopathic autism (IA; n = 15). Relative to controls, the FXS+A (p < 0.002) and FXS−A (p < 0.003) groups had impaired PPI. The FXS+A (p < 0.01) and FXS−A (p < 0.03) groups had lower PPI than the IA group. Prolonged startle latency was seen in the IA group. The differing PPI profiles seen in the FXS+A and IA indicates these groups may not share a common neurobiological abnormality of sensorimotor gating.

Titre : Increased Prepulse Inhibition and Sensitization of the Startle Reflex in Autistic Children Type de document : Texte imprimé et/ou numérique Auteurs : Gitte Falcher MADSEN, Auteur ; Niels BILENBERG, Auteur ; Cathriona CANTIO, Auteur ; Bob ORANJE, Auteur Article en page(s) : p.94-103 Langues : Anglais (eng) Mots-clés : autism spectrum disorders PPI sensorimotor gating sensitization children auditory processing Index. décimale : PER Périodiques Résumé : The relation between autism spectrum disorders (ASD) and schizophrenia is a subject of intense debate and research due to evidence of common neurobiological pathways in the two disorders. The objective of this study was to explore whether deficits in prepulse inhibition (PPI) of the startle reflex, as usually seen in schizophrenic patients, can be replicated in a group of children with ASD in comparison with a group of matched neuro-typically developed (NTD) controls. An additional aim was to explore possible psychophysiological subgroups within our ASD sample. In a case-control design, 35 ASD patients and 40 matched NTD controls were tested in a psychophysiological test battery. The PPI of the acoustic startle reflex was analyzed in 18 ASD subjects and 34 NTD controls. Habituation and sensitization were analyzed in 23 ASD subjects and 39 NTD controls. In trials with less intense prestimuli (76?dB), patients with ASD did not display the drop in percentage PPI normally found in healthy controls. In addition, ASD patients showed significantly increased sensitization compared with NTD controls. Combined, our results may reflect the hypersensitivity to sensory information in children with ASD. The relation to PPI deficits observed in schizophrenia is not apparent. Future research should study the developmental course of PPI deficits in ASD patients in a longitudinal design.
