Arousal-modulated memory encoding and retrieval in adults with autism spectrum disorder / Nico BAST in Autism Research, 15-9 (September 2022)
[article]
Titre : Arousal-modulated memory encoding and retrieval in adults with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Nico BAST, Auteur ; Sebastian B. GAIGG, Auteur ; Dermot M. BOWLER, Auteur ; Veit ROESSNER, Auteur ; Christine M. FREITAG, Auteur ; Melanie RING, Auteur Article en page(s) : p.1609-1620 Langues : Anglais (eng) Mots-clés : Adult Arousal/physiology Autism Spectrum Disorder/complications Humans Locus Coeruleus Pupil/physiology Recognition, Psychology Asd locus coeruleus-norepinephrine system memory pupillometry Index. décimale : PER Périodiques Résumé : Recently, we have shown that pupil dilation during a recognition memory task can serve as an index of memory retrieval difficulties in autism. At the time of publication, we were unaware of specific data-analysis methods that can be used to shed further light on the origins of such memory related pupil dilation. Specifically, by distinguishing "tonic" from "phasic" changes in pupil dilation and considering their temporal progression, it is possible to draw inferences about the functional integrity of a locus coeruleus-norepinephrine system (LC-NE) that is known to play a key role in regulating memory encoding and retrieval processes. We therefore apply these analyses to our previously published eye-tracking data of adults with ASD (NÂ =Â 24) and neurotypical development (TD, NÂ =Â 30) during the recognition memory task. In this re-analysis, we related pupil dilation during encoding and retrieval to recognition accuracy in a per-trial analysis of linear mixed models. In ASD, we replicated attenuated recognition accuracy, which was accompanied by attenuated pupil dilation during encoding and retrieval. Group differences in pupil dilation during retrieval occurred late during the trial (after 1.75s) and indicated an altered top-down processing like attenuated attribution of semantic salience in response to previously encoded stimuli. In addition, only in the ASD group were higher pupil dilation during encoding and lower pupil dilation during retrieval associated with decreased recognition accuracy. This supports altered modulation of memory encoding and retrieval in ASD, with LC-NE phasic activity as promising underlying mechanism. LAY SUMMARY: We investigated the changes of pupil size during memory testing in autism spectrum disorder. Adults with ASD remembered fewer items correctly than neurotypical individuals (TD). This reduced memory was related to increased pupillary responses at study and decreased pupil dilation at test only for adults with ASD indicating a different modulation of memory by the locus coeruleus.

Titre : Editorial Perspective: How to optimise frequency band neurofeedback for ADHD Type de document : Texte imprimé et/ou numérique Auteurs : Annet BLUSCHKE, Auteur ; Veit ROESSNER, Auteur ; Christian BESTE, Auteur Article en page(s) : p.457-461 Langues : Anglais (eng) Mots-clés : ADHD cognitive deficits neurofeedback treatment optimisation Index. décimale : PER Périodiques Résumé : Attention deficit/hyperactivity disorder (ADHD) is one of the most prevalent paediatric neuropsychiatric disorders and is characterised by hyperactivity, inattention and increased impulsivity. Children with ADHD are often also characterised by deficits in a variety of cognitive domains, including problems in working memory, a generally slower and more variable style of information processing and deficits in temporal processing, inhibitory functions and delay processing. Overarching executive functions like information updating, response inhibition and mental set shifting are also impaired in many, but not all, children with ADHD, demonstrating the neuropsychological heterogeneity characterising this disorder. Deficits in executive functions can persist into adulthood and have a substantial negative impact on everyday life. A variety of approaches are commonly considered for the treatment of ADHD (including pharmacological interventions, patient-centred cognitive-behavioural therapy approaches and specific teacher/parent training programmes). More recently, adding to this multimodal treatment approach, neurofeedback has grown in popularity as an intervention option for patients with ADHD. This article considers this intervention approach and the opportunities for optimising treatment for executive control dysfunctions in ADHD using theta/beta neurofeedback.

Titre : Editorial Perspective: Medical body modification in youth with gender dysphoria or body dysmorphic disorder - is current practice coherent and evidence-based? Type de document : Texte imprimé et/ou numérique Auteurs : Gregor KOHLS, Auteur ; Veit ROESSNER, Auteur Article en page(s) : p.1096-1100 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : In recent decades, there has been a steady increase in the number of people, including adolescents, undergoing medical body modification (MBM) to alter their physically healthy bodies in invasive and nearly irreversible ways through medical treatment (e.g. surgery). While MBM is often recommended for youth with persisting gender dysphoria (GD), in body dysmorphic disorder (BDD) it has been considered contraindicated. Here, we outline the current controversies surrounding MBM practice and recommendations in adolescents with GD versus those with BDD in order to better understand under what circumstances we may or may not support adolescents who want to change their bodies medically and often irreversibly. We compare the two disorders in terms of the overlap and uniqueness of their behavioural and psychological features. In doing so, we discuss limitations of the existing (often low-quality) evidence for and against MBM in young patients. We conclude that the currently available evidence is too preliminary and far from conclusive to make any robust recommendations in terms of benefits and harms of MBM in youth with persisting GD or BDD. However, we strongly recommend further urgent scientific discussions and systematic research efforts into more robust evaluations and the identification of more precise psychological characteristics that may serve as decision criteria for or against MBM particularly in those adolescents who did not respond to non-MBM, that is, psychiatric/psychological treatment and psychosocial support, if available at all. This will greatly benefit youth healthcare professionals in their challenging clinical practice of making decisions regarding MBM today and in the future.

Titre : Examining a model of anxiety in autistic adults Type de document : Texte imprimé et/ou numérique Auteurs : Saskia RIEDELBAUCH, Auteur ; Sebastian B. GAIGG, Auteur ; Tobias THIEL, Auteur ; Veit ROESSNER, Auteur ; Melanie RING, Auteur Article en page(s) : p.565-579 Langues : Anglais (eng) Mots-clés : alexithymia anxiety autism emotion regulation intolerance of uncertainty sensory processing Index. décimale : PER Périodiques Résumé : Anxiety disorders commonly occur in autism. Existing studies implicate intolerance of uncertainty, alexithymia, sensory processing differences and emotion regulation difficulties as influencing factors of anxiety in autism. To date, a few studies have considered the combination of these factors within the same sample. This study used structural equation modelling to test the prediction that intolerance of uncertainty and emotion regulation constitute more direct causes of anxiety in autism that mediate the influences of sensory processing difference and alexithymia as more sequential contributing factors. Autistic (n = 86) and non-autistic adults (n = 100) completed a battery of self-report questionnaires. Only when applied to each group separately, the broad predictions of the model were confirmed for the autistic group following data-driven additions of paths between sensory processing difference and anxiety and alexithymia implying that sensory processing difference contribute indirectly as well as directly to individual differences in anxiety. For the non-autistic group, model fit could only be achieved after removing autism-related traits and sensory processing differences as predictors of anxiety. These results suggest that aetiology and expression of anxiety in autism partially overlap with what is observed in the general population except that sensory processing differences appear to play a relatively unique role in the context of autism. Lay abstract Anxiety disorders are common in autism. Research studies have identified factors that influence anxiety in autism, such as difficulties with uncertain situations, difficulties understanding own emotions, differences in processing sensory input (related to our senses) and difficulties regulating emotions. To date, a few studies have considered the combination of these factors within the same sample. This study used structural equation modelling to test the contribution of these factors in autism. Autistic (n = 86) and non-autistic adults (n = 100) completed a battery of self-report questionnaires. Only when applied to each group separately, the broad predictions of the model were confirmed for the autistic group. The model confirmed that difficulties with uncertain situations and in regulating emotions play a central role in anxiety in autism. Difficulties understanding own emotions and differences in processing sensory input both contribute to anxiety indirectly through their respective interrelation with the other two factors (difficulties with uncertain situations and in regulating emotions). Importantly, the results imply that sensory processing differences contribute not only indirectly but also directly to individual differences in anxiety. For the non-autistic group, model fit could only be achieved after removing autism-related traits and sensory processing differences as predictors of anxiety. These results suggest that cause/development and expression of anxiety in autism partially overlap with what is observed in the general population except that sensory processing differences appear to play a relatively unique role in the context of autism.

AUGUST, Auteur ; Aribert ROTHENBERGER, Auteur ; Jürgen BAUDEWIG, Auteur ; Peter DECHENT, Auteur Article en page(s) : p.273-279 Mots-clés : Finger tapping motor network tourette syndrome primary sensorimotor cortex children Index. décimale : PER Périodiques Résumé : Background: Disturbances of motor circuitry are commonly encountered in Tourette syndrome (TS). The aim of this study was to investigate simple motor performance differences between boys with TS and healthy controls. Methods: We attempted to provide insight into motor network alterations by studying a group of treatment-naïve patients suffering from ‘pure’ TS, i.e., without comorbid symptomatology at an early stage of disease. We used functional MRI to compare activation patterns during right (preferred) and left (nonpreferred) index finger tapping between 22 TS boys (12.6 ± 1.7 years) and 22 age-matched healthy control boys. Results: Boys with TS revealed altered motor network recruitment for right (dominant) and left (nondominant) index finger tapping. Brain activation patterns in response to index finger tapping of the nonpreferred left hand reflected the most prominent differences, including activation decrease in contralateral sensorimotor cortex while recruiting premotor and prefrontal regions along with the left inferior parietal lobule to a greater extent. Conclusions: This study demonstrates clear functional differences of simple index finger tapping in early-stage TS. We suggest that this reflects the requirement for additional brain networks to keep a normal performance level during the actual task and adaptive mechanisms due to continuous tic suppression and performance in TS.
