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)

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.

Atypical Pupillary Light Reflex and Heart Rate Variability in Children with Autism Spectrum Disorder / Chathuri DALUWATTE in Journal of Autism and Developmental Disorders, 43-8 (August 2013)

Heart rate variability (HRV) was measured simultaneously to study potential impairments in the autonomic nervous system (ANS) associated with ASD. The results showed that the ASD group had significantly longer PLR latency, reduced relative constriction amplitude, and shorter constriction/redilation time than those of the TD group. Similar atypical PLR parameters were observed in the NDD group. A significant age effect on PLR latency was observed in children younger than 9 years in the TD group, but not in the ASD and NDD groups. Atypical HRV parameters were observed in the ASD and NDD groups. A significant negative correlation existed between the PLR constriction amplitude and average heart rate in children with an ASD, but not in children with typical development.

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 et/ou numérique 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.

The present study extends previous findings by examining visual filtering inhibitory ability within an older adolescent population. A flanker visual filtering task was administered to 36 adolescents with ASD and 44 adolescents without ASD (age: 11-20 years). Analysis revealed no evidence of group differences in visual filtering performance. Taken together with previous research, these results suggest that during early adolescence the previously observed impairment may resolve or compensatory strategies develop, allowing individuals with ASD to perform as well as their neurotypical peers.

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.
