Altered frontal connectivity as a mechanism for executive function deficits in fragile X syndrome / Lauren M. SCHMITT in Molecular Autism, 13 (2022)  

Public ISBD [article]  inMolecular Autism > 13 (2022) . - 47 p. Titre : Altered frontal connectivity as a mechanism for executive function deficits in fragile X syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Lauren M. SCHMITT, Auteur ; Joy LI, Auteur ; Rui LIU, Auteur ; Paul S. HORN, Auteur ; John A. SWEENEY, Auteur ; Craig A. ERICKSON, Auteur ; Ernest V. PEDAPATI, Auteur Article en page(s) : 47 p. Langues : Anglais (eng) Mots-clés : Child  Male  Humans  Female  Fragile X Syndrome  Executive Function  Autism Spectrum Disorder  Electroencephalography/methods  Brain  Connectivity  Eeg  Electroencephalography  Fxs  Fragile X syndrome  commercial or financial relationships that could be construed as a potential  conflict of interest for the current manuscript. Index. décimale : PER Périodiques Résumé : BACKGROUND: Fragile X syndrome (FXS) is the leading inherited monogenic cause of intellectual disability and autism spectrum disorder. Executive function (EF), necessary for adaptive goal-oriented behavior and dependent on frontal lobe function, is impaired in individuals with FXS. Yet, little is known how alterations in frontal lobe neural activity is related to EF deficits in FXS. METHODS: Sixty-one participants with FXS (54% males) and 71 age- and sex-matched typically-developing controls (TDC; 58% males) completed a five-minute resting state electroencephalography (EEG) protocol and a computerized battery of tests of EF, the Test of Attentional Performance for Children (KiTAP). Following source localization (minimum-norm estimate), we computed debiased weighted phase lag index (dWPLI), a phase connectivity value, for pairings between 18 nodes in frontal regions for gamma (30-55 Hz) and alpha (10.5-12.5 Hz) bands. Linear models were generated with fixed factors of group, sex, frequency, and connection. Relationships between frontal connectivity and EF variables also were examined. RESULTS: Individuals with FXS demonstrated increased gamma band and reduced alpha band connectivity across all frontal regions and across hemispheres compared to TDC. After controlling for nonverbal IQ, increased error rates on EF tasks were associated with increased gamma band and reduced alpha band connectivity. LIMITATIONS: Frontal connectivity findings are limited to intrinsic brain activity during rest and may not generalize to frontal connectivity during EF tasks or everyday function. CONCLUSIONS: We report gamma hyper-connectivity and alpha hypo-connectivity within source-localized frontal brain regions in FXS compared to TDC during resting-state EEG. For the first time in FXS, we report significant associations between EF and altered frontal connectivity, with increased error rate relating to increased gamma band connectivity and reduced alpha band connectivity. These findings suggest increased phase connectivity within gamma band may impair EF performance, whereas greater alpha band connectivity may provide compensatory support for EF. Together, these findings provide important insight into neurophysiological mechanisms of EF deficits in FXS and provide novel targets for treatment development.

Brief Report: Feasibility of the Probabilistic Reversal Learning Task as an Outcome Measure in an Intervention Trial for Individuals with Autism Spectrum Disorder / Lauren M. SCHMITT in Journal of Autism and Developmental Disorders, 52-9 (September 2022)

Index. décimale : PER Périodiques Résumé : Cognitive flexibility deficits are a hallmark feature of autism spectrum disorder (ASD), but few evidence-based behavioral interventions have successfully addressed this treatment target. Outcome measurement selection may help account for previous findings. The probabilistic reversal learning task (PRL) is a measure of cognitive flexibility previously validated for use in ASD, but its use as an outcome measure has not yet been assessed. The current study examined the feasibility, reproducibility, and sensitivity of PRL in a within-subjects trial of Regulating Together, a group-based intervention targeting emotion regulation. We demonstrated the PRL is highly feasible, showed test-retest reproducibility, and is sensitive to detect change following the intervention. Our findings demonstrate the PRL task may be a useful outcome measure of cognitive flexibility in future intervention trials in ASD.

We employed a pediatric cross-sectional sample (1,072 males, 338 females) from FORWARD, a clinic-based natural history study, to identify behavioral subtypes by latent class analysis. Input included co-occurring behavioral conditions, sleep and sensory problems, autistic behavior scales (SCQ, SRS-2), and the Aberrant Behavior Checklist revised for FXS (ABCFX). A 5-class solution yielded the most clinically meaningful, pharmacotherapy independent behavioral groups with distinctive SCQ, SRS-2, and ABCFX profiles, and adequate non-overlap (??71%): ?Mild? (31%), ?Moderate without Social Impairment? (32%), ?Moderate with Social Impairment? (7%), ?Moderate with Disruptive Behavior? (20%), and ?Severe? (9%). Our findings support FXS subtyping, for improving clinical management and therapeutic development.
