Altered perception-action binding modulates inhibitory control in Gilles de la Tourette syndrome / V. PETRUO in Journal of Child Psychology and Psychiatry, 60-9 (September 2019)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 60-9 (September 2019) . - p.953-962 Titre : Altered perception-action binding modulates inhibitory control in Gilles de la Tourette syndrome Type de document : Texte imprimé et/ou numérique Auteurs : V. PETRUO, Auteur ; B. BODMER, Auteur ; V. C. BRANDT, Auteur ; L. BAUMUNG, Auteur ; V. ROESSNER, Auteur ; A. MUNCHAU, Auteur ; Christian BESTE, Auteur Article en page(s) : p.953-962 Langues : Anglais (eng) Mots-clés : Tourette syndrome  cognitive control  event related potential  neurophysiology  response inhibition, inferior parietal cortex, theory of event coding Index. décimale : PER Périodiques Résumé : BACKGROUND: Gilles de la Tourette Syndrome (GTS) is a multifaceted neuropsychiatric developmental disorder with onset in childhood or adolescence and frequent remissions in early adulthood. A rather new emerging concept of this syndrome suggests that it is a disorder of purposeful actions, in which sensory processes and their relation to motor responses (actions) play a particularly important role. Thus, this syndrome might be conceived as a condition of altered 'perception-action binding'. In the current study, we test this novel concept in the context of inhibitory control. METHODS: We examined N = 35 adolescent GTS patients and N = 39 healthy controls in a Go/Nogo-task manipulating the complexity of sensory information triggering identical actions; i.e. to inhibit a motor response. This was combined with event-related potential recordings, EEG data decomposition and source localization. RESULTS: GTS patients showed worse performance compared to controls and larger performance differences when inhibitory control had to be exerted using unimodal visual compared to bimodal auditory-visual stimuli. This suggests increased binding between bimodal stimuli and responses leading to increased costs of switching between responses instructed by bimodal and those instructed by unimodal stimuli. The neurophysiological data showed that this was related to mechanisms mediating between stimulus evaluation and response selection; i.e. perception-action binding processes in the right inferior parietal cortex (BA40). CONCLUSIONS: Stimulus-action inhibition binding is stronger in GTS patients than healthy controls and affects inhibitory control corroborating the concept suggesting that GTS might be a condition of altered perception-action integration (binding); i.e. a disorder of purposeful actions.

An observational study of emotion regulation in children with Tourette syndrome / J. HAGSTRØM in Journal of Child Psychology and Psychiatry, 62-6 (June 2021)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 62-6 (June 2021) . - p.790-797 Titre : An observational study of emotion regulation in children with Tourette syndrome Type de document : Texte imprimé et/ou numérique Auteurs : J.

Previous studies have indicated that a comorbid diagnosis of attention-deficit/hyperactivity disorder (ADHD) is associated with emotional dysregulation in TS; however, this relationship has almost exclusively been studied using parent-reported questionnaires. METHODS: We examined emotion regulation (ER) with an observational measure in 150 medication-naïve children aged 7-12 allocated to four groups: Forty-nine children with TS, 23 children with ADHD, 16 children with TS + ADHD, and 62 typically developing controls. We assessed participants' ER ability, as well as parent-child interactions in the context of a complex puzzle task, and coded the observed behavior with the Tangram Emotion Coding Manual (TEC-M). We examined group differences in ER, as well as associations between ER and severity of symptoms pertaining to TS and ADHD. RESULTS: Children with TS did not differ from controls in their ER ability. However, children with ADHD and TS + ADHD had more problems with ER than those with TS only and controls. Finally, parents of children with ADHD displayed more tension during the experimental task. ER ability was not associated with tic severity nor premonitory urges; however, better ER ability was associated with less severe symptoms of ADHD. CONCLUSIONS: This study is the first to evaluate ER with an observational, clinician-rated measure in a controlled social setting in children with TS. Our findings support earlier questionnaire-based studies by showing impaired ER in children with TS + ADHD, but not in children with TS without comorbidity. These findings inform our understanding of the phenomenology of emotional dysregulation in TS and the role of comorbid disorders.

Finger tapping-related activation differences in treatment-naïve pediatric Tourette syndrome: a comparison of the preferred and nonpreferred hand / Veit ROESSNER in Journal of Child Psychology and Psychiatry, 54-3 (March 2013)

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.

Increased putamen and callosal motor subregion in treatment-naïve boys with Tourette syndrome indicates changes in the bihemispheric motor network / Veit ROESSNER in Journal of Child Psychology and Psychiatry, 52-3 (March 2011)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 52-3 (March 2011) . - p.306-314 Titre : Increased putamen and callosal motor subregion in treatment-naïve boys with Tourette syndrome indicates changes in the bihemispheric motor network Type de document : Texte imprimé et/ou numérique Auteurs : Veit ROESSNER, Auteur ; Sebastian OVERLACK, Auteur ; Carsten SCHMIDT-SAMOA, Auteur ; Jürgen BAUDEWIG, Auteur ; Peter DECHENT, Auteur ; Aribert ROTHENBERGER, Auteur ; Gunther HELMS, Auteur Année de publication : 2011 Article en page(s) : p.306-314 Langues : Anglais (eng) Mots-clés : Tic disorders  Tourette syndrome  corpus callosum  basal ganglia  magnetic resonance imaging  child Index. décimale : PER Périodiques Résumé : Background:  Despite an increasing number of studies, findings of structural brain alterations in patients with Tourette syndrome are still inconsistent. Several confounders (comorbid conditions, medication, gender, age, IQ) might explain these discrepancies. In the present study, these confounders were excluded to identify differences in basal ganglia and corpus callosum size that can be ascribed more probably to Tourette syndrome per se. Methods:  High-resolution T1-weighted structural magnetic resonance images of 49 boys with Tourette syndrome were compared with those of 42 healthy boys. The groups were matched for IQ and age (9 to 15 years). Boys with comorbid conditions and previous treatment were excluded. Volumes of gray and white matter, cerebrospinal fluid as well as the size of the basal ganglia, the thalamus, the corpus callosum and its subregions were estimated. Results:  The left and right putamen and subregion 3 of the corpus callosum were larger in boys with Tourette syndrome than in healthy controls. No differences were found in volumes of caudate nucleus, globus pallidus or thalamus of each hemisphere or in total callosal size and its other subregions. Conclusions:  Bilateral enlargement of the putamen may reflect dopaminergic dysfunction or neuroimmunologic alterations (PANDAS) underlying Tourette syndrome. The larger callosal motor subregion 3 might be a consequence of daily tic activity. Previous divergent volumetric findings might be ascribed to confounding variables like comorbid conditions or medication, or to different imaging methods.

Inhibitory Deficits in Tourette Syndrome: A Function of Comorbidity and Symptom Severity / Sally OZONOFF in Journal of Child Psychology and Psychiatry, 39-8 (November 1998)

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 39-8 (November 1998) . - p.1109-1118 Titre : Inhibitory Deficits in Tourette Syndrome: A Function of Comorbidity and Symptom Severity Type de document : Texte imprimé et/ou numérique Auteurs : Sally OZONOFF, Auteur ; David L.

MCMAHON, Auteur ; Francis FILLOUX, Auteur Année de publication : 1998 Article en page(s) : p.1109-1118 Langues : Anglais (eng) Mots-clés : Tourette syndrome  information processing  classification  comorbidity Index. décimale : PER Périodiques Résumé : This study examined central inhibitory function in children with Tourette syndrome (TS; N= 46) and normally developing controls (N= 22) matched on age, gender, and IQ. A negative priming task measured the ability to inhibit processing of irrelevant distractor stimuli presented on a visual display. Initial analyses indicated that participants with Tourette syndrome did not differ significantly in inhibitory function from controls. However, when the large Tourette syndrome sample was separated into subgroups, one without evidence of comorbidity (N= 23) and the other meeting research criteria for either AD/HD, OCD, or both (N= 23), it became evident that individuals with Tourette syndrome with comorbid conditions tended to perform less well than the control group, whereas those without comorbidity performed much like controls. Similarly, when the large Tourette syndrome sample was divided into two subgroups on the basis of severity of symptomatology (N= 23 in each), those with more numerous and severe symptoms of Tourette syndrome, AD/HD, and OCD performed significantly less well than both controls and Tourette syndrome subjects with fewer and less severe symptoms. This suggests that neuropsychological impairment occurs as a function of comorbidity and symptom severity in Tourette syndrome. It also suggests that categorical diagnoses alone may be less useful than dimensional methods for predicting cognitive impairment in individuals with Tourette syndrome.
