Relationship of the Acoustic Startle Response and Its Modulation to Emotional and Behavioral Problems in Typical Development Children and Those with Autism Spectrum Disorders / Hidetoshi TAKAHASHI in Journal of Autism and Developmental Disorders, 46-2 (February 2016)

We investigated acoustic startle response (ASR) modulations in 17 children with ASD and 27 with typical development (TD). Compared to TD, children with ASD had larger ASR magnitude to weak stimuli and more prolonged peak startle-latency. We could not find significant difference of prepulse inhibition (PPI) or habituation in ASD children compared to TD. However, habituation and PPI at 70-dB prepulses were negatively related to several subscales of Social Responsiveness Scale and the Strengths and Difficulties Questionnaire, when considering all children. Comprehensive investigation of ASR and its modulation might increase understanding of the neurophysiological impairments underlying ASD and other mental health problems in children.

Stability of the acoustic startle response and its modulation in children with typical development and those with autism spectrum disorders: A one-year follow-up / Hidetoshi TAKAHASHI in Autism Research, 10-4 (April 2017)  

Public ISBD [article]  inAutism Research > 10-4 (April 2017) . - p.673-679 Titre : Stability of the acoustic startle response and its modulation in children with typical development and those with autism spectrum disorders: A one-year follow-up Type de document : Texte imprimé et/ou numérique Auteurs : Hidetoshi TAKAHASHI, Auteur ; Takayuki NAKAHACHI, Auteur ; Andrew STICKLEY, Auteur ; Makoto ISHITOBI, Auteur ; Yoko KAMIO, Auteur Article en page(s) : p.673-679 Langues : Anglais (eng) Mots-clés : autism spectrum disorders  acoustic startle response  prepulse inhibition  sensory-motor gating  habituation  startle latency  long-term stability  test–retest reliability Index. décimale : PER Périodiques Résumé : Auditory hyper-reactivity is a common sensory–perceptual abnormality that interrupts behavioral adaptations in autism spectrum disorders (ASD). Recently, prolonged acoustic startle response (ASR) latency and hyper-reactivity to weak acoustic stimuli were reported in children with ASD. Indexes of ASR and its modulation are known to be stable biological markers for translational research in the adult population. However, little is known about the stability of these indexes in children. Thus, the objective of our study was to investigate the stability of neurophysiological ASR indexes in children with ASD and typical development (TD). Participants included 12 children with ASD and 24 with TD. Mean startle magnitudes to acoustic stimuli presented at 65–105 dB in increments of 10 dB were analyzed. Average peak startle latency (PSL), ASR modulation of habituation, and prepulse inhibition were also analyzed. These startle measures were examined after a follow-up period of 15.7?±?5.1 months from baseline. At both baseline and in the follow-up period, children with ASD had significantly greater startle magnitudes to weak stimuli of 65–85 dB and more prolonged PSL compared with controls. Intraclass correlation coefficients for these ASR measures between both periods were 0.499–0.705. None of the ASR measures differed significantly between the two periods. Our results suggest that prolonged PSL and greater startle magnitudes to weak stimuli in children with ASD might serve as moderately stable neurophysiological indexes of ASD.
