The current study focused primarily on meeting the unique training needs of Black adolescents with autism spectrum disorder (ASD). A single case design was used to evaluate the initial efficacy and acceptability of a culturally responsive training method. Preliminary evidence about the physiological ramifications of police contact were also collected to begin to examine the broader behavioral and psychophysiological nature of youth?s experiences. The current experimental design included in-person simulated contexts that youth, and caregivers, endorsed as relevant to their normal lives, which greatly strengthened the ecological validity of the approach.

Association of Rigid-Compulsive Behavior with Functional Constipation in Autism Spectrum Disorder / Sarah MARLER in Journal of Autism and Developmental Disorders, 47-6 (June 2017)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 47-6 (June 2017) . - p.1673-1681 Titre : Association of Rigid-Compulsive Behavior with Functional Constipation in Autism Spectrum Disorder Type de document : texte imprimé Auteurs : Sarah MARLER, Auteur ; Bradley J.

We used the Questionnaire on Pediatric Gastrointestinal Symptoms—Rome III to assess FC symptoms in 108 children with ASD. As hypothesized, FC was associated with parent ratings on the Repetitive Behavior Scales—Revised (RBS-R) Compulsive, Ritualistic, and Sameness subscales in the overall population. Of note, FC was less common in children who were not taking medications that target behavior or treat FC. In the medication-free children, rigid-compulsive behavior was not significantly associated with FC. More research is needed to understand the mechanisms underlying these associations.

Beta-adrenergic antagonism alters functional connectivity during associative processing in a preliminary study of individuals with and without autism / John P. 2nd HEGARTY in Autism, 24-3 (April 2020)  

Public ISBD [article]  inAutism > 24-3 (April 2020) . - p.795-801 Titre : Beta-adrenergic antagonism alters functional connectivity during associative processing in a preliminary study of individuals with and without autism Type de document : texte imprimé Auteurs : John P. 2nd HEGARTY, Auteur ; Rachel M.

BEVERSDORF, Auteur Article en page(s) : p.795-801 Langues : Anglais (eng) Mots-clés : beta-blockers  fronto-parietal control network  functional magnetic resonance imaging  noradrenergic  propranolol  semantic fluency Index. décimale : PER Périodiques Résumé : Beta-adrenergic antagonism (e.g. propranolol) has been associated with cognitive/behavioral benefits following stress-induced impairments and for some cognitive/behavioral domains in individuals with autism spectrum disorder. In this preliminary investigation, we examined whether the benefits of propranolol are associated with functional properties in the brain. Adolescents/adults (mean age = 22.54 years) with (n = 13) and without autism spectrum disorder (n = 13) attended three sessions in which propranolol, nadolol (beta-adrenergic antagonist that does not cross the blood-brain barrier), or placebo was administered before a semantic fluency task during functional magnetic resonance imaging. Autonomic nervous system measures and functional connectivity between language/associative processing regions and within the fronto-parietal control, dorsal attention, and default mode networks were examined. Propranolol was associated with improved semantic fluency performance, which was correlated with the baseline resting heart rate. Propranolol also altered network efficiency of regions associated with semantic processing and in an exploratory analysis reduced functional differences in the fronto-parietal control network in individuals with autism spectrum disorder. Thus, the cognitive benefits from beta-adrenergic antagonism may be generally associated with improved information processing in the brain in domain-specific networks, but individuals with autism spectrum disorder may also benefit from additional improvements in domain-general networks. The benefits from propranolol may also be able to be predicted from baseline autonomic nervous system measures, which warrants further investigation.

Bidirectional relationship between internalizing symptoms and gastrointestinal problems in youth with Autism Spectrum Disorder / Kristen N. DOVGAN in Journal of Autism and Developmental Disorders, 53-11 (November 2023)

FERGUSON, Auteur Article en page(s) : p.4488-4494 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Many youth with autism spectrum disorder (ASD) experience co-occurring conditions, such as gastrointestinal (GI) problems and internalizing symptoms. However, the relationship among these co-occurring problems is not well-understood. We analyzed parent reports of GI problems and internalizing symptoms of 621 youth with ASD using path models in a structural equation modeling framework. The best-fitting model was a bidirectional model wherein internalizing symptoms, including withdrawn and anxious behavior, were correlated with GI problems, including constipation, diarrhea, nausea, and stomach pain. This study provides a better understanding of the relationship among co-occurring conditions in youth with ASD and should encourage clinicians to consider treatment of underlying internalizing symptoms or GI problems when providing services for individuals with ASD.

Brief Report: Whole Blood Serotonin Levels and Gastrointestinal Symptoms in Autism Spectrum Disorder / Sarah MARLER in Journal of Autism and Developmental Disorders, 46-3 (March 2016)

Co-occurring gastrointestinal (GI) symptoms are also common in ASD but have not previously been examined in relationship with hyperserotonemia, despite the synthesis of serotonin in the gut. In 82 children and adolescents with ASD, we observed a correlation between a quantitative measure of lower GI symptoms and whole blood serotonin levels. No significant association was seen between functional constipation diagnosis and serotonin levels in the hyperserotonemia range, suggesting that this correlation is not driven by a single subgroup. More specific assessment of gut function, including the microbiome, will be necessary to evaluate the contribution of gut physiology to serotonin levels in ASD.
