The purpose of this study was to evaluate use of the Screening Tool for Autism in Toddlers and Young Children (STAT) when used by primary care practitioners (n = 10) across a statewide system of early diagnosis set within seven United States primary care practices. Specifically, for 130, 14- to 48-month-old children, we examined (1) agreement between STAT classification and Autism Diagnostic Observation Schedule, Second Edition (ADOS-2) outcome and expert diagnosis of autism, (2) characteristics of children with inaccurate STAT classifications, (3) consistency between STAT classification and primary care practitioner diagnosis, and (4) the relationship between STAT/primary care practitioner classification and expert diagnosis. The STAT demonstrated good concurrent validity with the ADOS-2 (77% agreement). Concordance between specialty trained primary care practitioners with expert diagnosis was 80%-87% across three age-based subgroups of children. Children misclassified by the STAT were older, had higher developmental and adaptive skills, and lower autism symptoms. Primary care practitioner diagnosis aligned with STAT categorical risk classification in 86% of cases, and 73% of consistent classifications between STAT and primary care practitioner diagnosis matched expert diagnosis. Overall, the STAT demonstrates good accuracy when used by non-specialists as part of a diagnostic evaluation.Lay summary Specialists conduct autism evaluations using tools that are expensive and difficult to get trained on. Families often wait a long time and travel far to get a diagnosis for their child. To help with this problem, primary care practitioners can be trained to provide evaluations in local communities. However, usable and accurate tools developed for non-specialists are needed. The Screening Tool for Autism in Toddlers and Young Children (STAT) was created for this purpose, but limited research has been done on accuracy of the tool in community primary care. This study tested the STAT when used by primary care practitioners as part of a diagnostic evaluation in 130, 14- to 48-month-old children. We tested (1) STAT agreement with the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2), and diagnosis based on an expert research evaluation, and (2) the relationship between STAT classification, primary care practitioner diagnosis, and expert diagnosis. STAT classification matched the ADOS-2 in 77% of cases and expert diagnosis in 78% of cases. Autistic children incorrectly classified by the STAT were older, had higher developmental and adaptive skills, and fewer autism symptoms. In 86% of cases, the STAT classification agreed with primary care practitioner diagnosis. STAT classification, primary care practitioner diagnosis, and expert diagnosis agreed in 73% of cases. Overall, the STAT shows good accuracy when used by primary care practitioners as part of a community primary care autism evaluation.

Associations between sensory processing and electrophysiological and neurochemical measures in children with ASD: an EEG-MRS study / Sarah PIERCE in Journal of Neurodevelopmental Disorders, 13 (2021)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 13 (2021) Titre : Associations between sensory processing and electrophysiological and neurochemical measures in children with ASD: an EEG-MRS study Type de document : texte imprimé Auteurs : Sarah PIERCE, Auteur ; Girija KADLASKAR, Auteur ; David A. EDMONDSON, Auteur ; Rebecca MCNALLY KEEHN, Auteur ; Ulrike DYDAK, Auteur ; Brandon KEEHN, Auteur Langues : Anglais (eng) Mots-clés : Adolescent  Autism Spectrum Disorder/diagnostic imaging  Child  Electroencephalography  Female  Humans  Magnetic Resonance Imaging  Magnetic Resonance Spectroscopy  Male  Perception  Alpha power  Autism spectrum disorder  Eeg  Gaba  Glutamate  Mrs  Sensory processing Index. décimale : PER Périodiques Résumé : BACKGROUND: Autism spectrum disorder (ASD) is associated with hyper- and/or hypo-sensitivity to sensory input. Spontaneous alpha power, which plays an important role in shaping responsivity to sensory information, is reduced across the lifespan in individuals with ASD. Furthermore, an excitatory/inhibitory imbalance has also been linked to sensory dysfunction in ASD and has been hypothesized to underlie atypical patterns of spontaneous brain activity. The present study examined whether resting-state alpha power differed in children with ASD as compared to TD children, and investigated the relationships between alpha levels, concentrations of excitatory and inhibitory neurotransmitters, and atypical sensory processing in ASD. METHODS: Participants included thirty-one children and adolescents with ASD and thirty-one age- and IQ-matched typically developing (TD) participants. Resting-state electroencephalography (EEG) was used to obtain measures of alpha power. A subset of participants (ASD = 16; TD = 16) also completed a magnetic resonance spectroscopy (MRS) protocol in order to measure concentrations of excitatory (glutamate + glutamine; Glx) and inhibitory (GABA) neurotransmitters. RESULTS: Children with ASD evidenced significantly decreased resting alpha power compared to their TD peers. MRS estimates of GABA and Glx did not differ between groups with the exception of Glx in the temporal-parietal junction. Inter-individual differences in alpha power within the ASD group were not associated with region-specific concentrations of GABA or Glx, nor were they associated with sensory processing differences. However, atypically decreased Glx was associated with increased sensory impairment in children with ASD. CONCLUSIONS: Although we replicated prior reports of decreased alpha power in ASD, atypically reduced alpha was not related to neurochemical differences or sensory symptoms in ASD. Instead, reduced Glx in the temporal-parietal cortex was associated with greater hyper-sensitivity in ASD. Together, these findings may provide insight into the neural underpinnings of sensory processing differences present in ASD.

Attentional networks in children and adolescents with autism spectrum disorder / Brandon KEEHN in Journal of Child Psychology and Psychiatry, 51-11 (November 2010)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 51-11 (November 2010) . - p.1251-1259 Titre : Attentional networks in children and adolescents with autism spectrum disorder Type de document : texte imprimé Auteurs : Brandon KEEHN, Auteur ; Alan J. LINCOLN, Auteur ; Ralph-Axel MULLER, Auteur ; Jeanne TOWNSEND, Auteur Année de publication : 2010 Article en page(s) : p.1251-1259 Langues : Anglais (eng) Mots-clés : Autism reaction-time visual-attention alerting orienting executive-control Index. décimale : PER Périodiques Résumé : Background:  Individuals diagnosed with autism spectrum disorder (ASD) exhibit lifelong abnormalities in the adaptive allocation of visual attention. The ubiquitous nature of attentional impairments in ASD has led some authors to hypothesize that atypical attentional modulation may be a factor in the development of higher-level sociocommunicative deficits. Method:  Participants were 20 children with ASD and 20 age- and Nonverbal IQ-matched typically developing (TD) children. We used the Attention Network Test (ANT) to investigate the efficiency and independence of three discrete attentional networks: alerting, orienting, and executive control. Additionally, we sought to investigate the relationship between each attentional network and measures of sociocommunicative symptom severity in children with ASD. Results:  Results indicate that the orienting, but not alerting or executive control, networks may be impaired in children with ASD. In contrast to TD children, correlational analyses suggest that the alerting and executive control networks may not function as independently in children with ASD. Additionally, an association was found between the alerting network and social impairment and between the executive control network and IQ in children with ASD. Conclusions:  The results provide further evidence of an impairment in the visuospatial orienting network in ASD and suggest that there may be greater interdependence of alerting and executive control networks in ASD. Furthermore, decreased ability to efficiently modulate levels of alertness was related to increased sociocommunicative deficits, suggesting that domain-general attentional function may be associated with ASD symptomatology.

Atypical Hemispheric Specialization for Faces in Infants at Risk for Autism Spectrum Disorder / Brandon KEEHN in Autism Research, 8-2 (April 2015)

To investigate the earliest manifestations of these features, we examined lateralization of event-related gamma-band coherence to faces during the first year of life in infants at high risk for autism (HRA; defined as having an older sibling with ASD) who were compared with low-risk comparison (LRC) infants, defined as having no family history of ASD. Participants included 49 HRA and 46 LRC infants who contributed a total of 127 data sets at 6 and 12 months. Electroencephalography was recorded while infants viewed images of familiar/unfamiliar faces. Event-related gamma-band (30–50 Hz) phase coherence between anterior–posterior electrode pairs for left and right hemispheres was computed. Developmental trajectories for lateralization of intra-hemispheric coherence were significantly different in HRA and LRC infants: by 12 months, HRA infants showed significantly greater leftward lateralization compared with LRC infants who showed rightward lateralization. Preliminary results indicate that infants who later met criteria for ASD were those that showed the greatest leftward lateralization. HRA infants demonstrate an aberrant pattern of leftward lateralization of intra-hemispheric coherence by the end of the first year of life, suggesting that the network specialized for face processing may develop atypically. Further, infants with the greatest leftward asymmetry at 12 months where those that later met criteria for ASD, providing support to the growing body of evidence that atypical hemispheric specialization may be an early neurobiological marker for ASD.

The current study examined overt orienting to caregiver-initiated touch in 12-month-olds at high risk for ASD (HRA) with (HRA+) and without (HRA-) a later diagnosis of ASD compared to low-risk comparison infants. Findings indicate that infants that go on to receive a diagnosis of ASD may more frequently fail to shift their attention in response to caregiver touch and when they do, they may be more likely to orient away from touch. Additionally, failure to respond to touch predicts ADOS severity scores at outcome suggesting that atypical response to touch may be an early indicator of autism severity.
