The purpose of the present study was to estimate the factors linked to the prognosis of children with provisional tic disorder (PTD). We conducted a prospective cohort study enrolled children with PTD who were subsequently followed-up at three-month intervals for 1 year post-enrolment. A total of 259 PTD patients were included in the final analysis. At the end of the follow-up period, 77 (30%) of the patients had achieved clinical remission. Result of the LASSO logistic regression analysis revealed that a disease duration >3 months (OR=4.20, 95% CI 1.20–14.73), moderate/severe tic severity (OR=5.57, 95% CI 2.26–13.76), and comorbid behavioral problems (OR=2.78, 95% CI 1.15–6.69) were significant factors linked to remission in the PTD patients. The path analysis model showed that comorbid behavioral problems and recurrence partially mediated the association between tic severity and remission, with a mediating effect of 37%. Conclusions: We have identified several significant factors linked to prognosis in children with PTD, including comorbid behavioral problems and recurrence, which were found to be important mediators. These findings provide new insights for the clinical management of patients with PTD. [ABSTRACT FROM AUTHOR]

Background and Purpose: Current pharmacotherapies for Tourette syndrome (TS) are often unsatisfactory and poorly tolerated, underscoring the need for novel treatments. Insufficient striatal acetylcholine has been suggested to contribute to tic ontogeny. Thus, we tested whether activating M1 and/or M4 receptors—the two most abundant muscarinic receptors in the striatum—reduced tic‐related behaviours in mouse models of TS. Experimental Approach: Studies were conducted using CIN‐d and D1CT‐7 mice, two TS models characterized by early‐life depletion of striatal cholinergic interneurons and cortical neuropotentiation, respectively. First, we tested the effects of systemic and intrastriatal xanomeline, a selective M1/M4 receptor agonist, on tic‐like and other TS‐related responses. Then, we examined whether xanomeline effects were reduced by either M1 or M4 antagonists or mimicked by the M1/M3 agonist cevimeline or the M4 positive allosteric modulator (PAM) VU0467154. Finally, we measured striatal levels of M1 and M4 receptors and assessed the impact of VU0461754 on the striatal expression of the neural marker activity c‐Fos. Key Results: Systemic and intrastriatal xanomeline reduced TS‐related behaviours in CIN‐d and D1CT‐7 mice. Most effects were blocked by M4, but not M1, receptor antagonists. VU0467154, but not cevimeline, elicited xanomeline‐like ameliorative effects in both models. M4, but not M1, receptors were down‐regulated in the striatum of CIN‐d mice. Additionally, VU0467154 reduced striatal c‐Fos levels in these animals. Conclusion and Implications: Activation of striatal M4, but not M1, receptors reduced tic‐like manifestations in mouse models, pointing to xanomeline and M4 PAMs as novel putative therapeutic strategies for TS.

Background: Oral aripiprazole exhibits favorable clinical efficacy and safety in the suppression of tics in children and adolescents with tic disorders. This study aims to evaluate and compare the cost-effectiveness of high-dose and low-dose aripiprazole in children and adolescents with tic disorders from the perspective of the Chinese healthcare system. Methods: A questionnaire survey was conducted on 146 patients with tic disorders, of whom 144 completed EQ-5D-Y and YGTSS. Four models were built to convert YGTSS onto EQ-5D-Y utility using two mapping algorithms. We constructed a decision tree model containing efficacy and safety to compare the cost-effectiveness of high-dose and low-dose aripiprazole based on our mapping function. Results: The GLM with model 1 (YGTSS total tic scores) was selected as the preferred function in our decision tree model. The base case cost-effectiveness analysis showed that compared to low-dose aripiprazole, high-dose aripiprazole improves effectiveness by 0.001QALYs and increases the overall cost by $197.99, resulting in an ICER of $174339.22 per QALY, which exceeds three times the gross domestic product per capita. Hence, high-dose aripiprazole is not likely to be a cost-effective option for child patients with tic disorders. One-way sensitivity analysis and probabilistic sensitivity analysis showed that these results is robust. Conclusion: On the basis of currently available data, low-dose aripiprazole may be a safe, effective, and economical dosage for children and adolescents with tic disorders. Limitations: The main limitation of our study is the lack of utility directly used for cost-effectiveness analysis. We obtained the utility of patients with tic disorders indirectly by the mapping function. This may introduce some bias and uncertainty. And it is a limitation to use the direct medical costs of Germany in our model. Although we converted it to the equivalent value of China using purchasing power parities, caution should be exercised when interpreting the results of this study. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Gamification of behavioral intervention for tic disorders (TDs) potentially enhances compliance and offers key clinical advantages. By delivering immediate positive feedback upon tic‐suppression, games may counteract negative reinforcement, which presumably contribute to tic consolidation by relieving uncomfortable premonitory urges. Objectives: We developed a gamified protocol (XTics), which leverages this potential by combining gamified tic‐triggering with immediate feedback, and evaluated its clinical value in enhancing tic suppression. Methods: XTics encompasses two conditions: Immediate and Contingent Reward (ICR), where game progression is contingent upon successful tic suppression, and Delayed Reward (DR), where game events' outcomes are random. Employing a randomized crossover design, 35 participants (aged 7–15 years) underwent daily gaming sessions over a week per condition. Improvements in our primary measures, including the inter‐tic interval (ITI) and tic severity assessment by blinded evaluators (Yale Global Tic Severity‐Total Tic Score [YGTSS‐TTS], Rush), and parents (Parent Tic Questionnaire [PTQ]), were compared between ICR and DR, and assessed across conditions for the 4‐week protocol. Results: No participant voluntarily left the study before completing its two‐phase protocol. As expected, ITI showed significantly larger improvement (Z = 4.19, P = 2.85 × 10–5) after ICR (1442 ± 2250%) versus DR (242 ± 493%) training, increasing at a higher pace (t(67) = 3.15, P = 0.0025). Similarly, Rush tic severity scores reduced more post‐ICR versus DR (t(47) = 3.47, P = 0.002). We observed a clinically significant reduction of 25.69 ± 23.39% in YGTSS‐TTS following a f4‐week protocol including both conditions. Parent‐reported tic severity decreased by 42.99 ± 31.69% from baseline to 3 months post‐treatment. Conclusions: The combination of gamified tic‐triggering with immediate and contingent rewards demonstrates a promising approach for enhancing treatment efficacy in TDs, boosting traditional therapeutic methods. © 2024 The Author(s).

Functional neuroimaging studies demonstrate disinhibition of the cortico-striatal-thalamo-cortical circuit. However, structural imaging studies revealed conflicting results, some suggesting smaller volumes of the caudate nucleus (CN) in children with Gilles de la Tourette syndrome (TS). Here we wanted to find out whether transcranial sonography (TCS) detects alterations of raphe nuclei, substantia nigra, lenticular nucleus (LN), or CN in children with Tic disorder or TS (TIC/TS).The study included 25 treatment-naive children (age: 12.2 ± 2.5 years) with a DSM-V based diagnosis of Tic disorder or TS (10 subjects), without other psychiatric or neurologic diagnosis, and 25 healthy controls (age: 12.17 ± 2.57 years), matched for age and sex. Parental rating of behavioral, emotional abnormalities, somatic complaints and social competencies of the participants were assessed using the Child Behavior Check List (CBCL/4-18R). TCS of deep brain structures was conducted through the preauricular acoustic bone windows using a 2.5-MHz phased-array ultrasound system. Fisher's exact test and Mann-Whitney-U test were used for comparisons between TIC/TS patients and healthy volunteers. The number of participants with hyperechogenic area of left CN in the TIC/TS sample was increased, compared to the healthy control group. TIC/TS patients with hyperechogenic CN showed an increased occurrence of thought- and obsessive-compulsive problems. This TCS study revealed pathologic structural changes in CN, its higher occurrence in TIC/TS compared to healthy controls and the relation to comorbidity of thought problems. Further research should focus on the molecular cause of these alterations, probably the disturbed iron metabolism. [ABSTRACT FROM AUTHOR]

Tourette syndrome (TS) is a high-incidence neurobehavioral disorder that generally begins in childhood. Several factors play a role in its etiology, including genetic influence and auto-immune activation by streptococcal infections. In general, symptoms subside after the end of adolescence, but, in a significant number of patients, they remain in adulthood. In this study, we evaluated temporal variations in the two core clinical features of TS including tics and obsessive–compulsive disorder (OCD) symptoms. An observational longitudinal study lasting 15 months (2017–2019) was conducted on a cohort of 24 people recruited in Milan (Italy) who were diagnosed with a subtype of TS known as obsessive–compulsive tic disorder. Inclusion criteria included a global score of the Yale global tic severity scale (Y-GTSS) > 50, a Yale–Brown obsessive–compulsive scale (Y-BOCS) global score > 15, and TS onset at least one year prior. Y-GTSS and Y-BOCS data were acquired at six time points, together with local environmental data. Tics, but not OCD symptoms, were found to be more severe in spring and summer compared with winter and autumn (p < 0.001). Changes in tics displayed an appreciable oscillation pattern in the same subject and also a clear synchrony among different subjects, indicating an external orchestrating factor. Ambient temperature showed a significant correlation with Y-GTSS measurements (p < 0.001). We argue that the increase in tics observed during hot seasons can be related to increasing ambient temperature. We believe that our results can shed light on the seasonal dynamics of TS symptomatology and provide clues for preventing their worsening over the year. [ABSTRACT FROM AUTHOR]

Self-injurious behavior (SIB) is a well-known phenomenon in patients with chronic tic disorders (CTD). To investigate prospectively symptomatology of SIB in adults with CTD, we developed and validated the self-injurious behavior scale for tic disorders (SIBS-T). Patients completed the SIBS-T and a variety of assessments for tics and comorbidities. We investigated SIB frequency, internal consistency of the SIBS-T, and carried out an exploratory factor analysis (EFA). We enrolled n = 123 adult patients with CTD. SIB was reported by n = 103 patients (83.7%). The most frequently reported SIB were beating/pushing/throwing and were found in 79.6% of cases. Patients with SIB had significantly higher tic severity measured with the Adult Tic Questionnaire (ATQ) (p = 0.002) as well as higher severity of psychiatric comorbidities such as obsessive–compulsive symptoms (OCS) (p < 0.001,), attention deficit/hyperactivity disorder (ADHD) (p < 0.001,), and anxiety (p = 0.001). In addition, patients with SIB had significantly lower quality of life (p = 0.002). Pearson correlations demonstrated significant associations between SIB and severity of tics (p < 0.001), depression (p = 0.005), ADHD (p = 0.008), and borderline personality traits (p = 0.014). Consequently, higher SIBS-T also correlated with greater impairment of quality of life (p < 0.001). The internal consistency of the SIBS-T was good (α = 0.88). The EFA confirmed a single factor underlying the SIBS-T. [ABSTRACT FROM AUTHOR]

Background Objectives Methods Results Conclusions Chronic tic disorders (CTD) are multifaceted disorders characterized by multiple motor and/or vocal tics. They are often associated with complex tics including echophenomena, paliphenomena, and coprophenomena as well as psychiatric comorbidities such as attention deficit/hyperactivity disorder (ADHD) and obsessive‐compulsive disorder (OCD).Our goal was to uncover the inter‐relational structure of CTD and comorbid symptoms in children and adults and to understand changes in symptom structure across development.We used network and graph analyses to uncover the structure of association of symptoms in childhood/adolescence (n = 529) and adulthood (n = 503) and how this structure might change from childhood to adulthood, pinpointing core symptoms as a main target for interventions.The analysis yielded core symptom networks in young and adult patients with CTD including complex tics and tic‐related phenomena as well as touching people and objects. Core symptoms in childhood also included ADHD symptoms, whereas core symptoms in adults included symptoms of OCD instead. Interestingly, self‐injurious behavior did not play a core role in the young CTD network, but became one of the central symptoms in adults with CDT. In addition, we found strong connections between complex motor and vocal tics as well as echolalia and echopraxia.Next to other complex tics, echophenomena, paliphenomena, and coprophenomena can be regarded core symptoms of CTD. ADHD symptoms are closely related to CTD in childhood, whereas symptoms of OCD and self‐injurious behavior are closely associated with CTD in adults. Our results suggest that a differentiation between motor and vocal tics is somewhat arbitrary. [ABSTRACT FROM AUTHOR]

Background: Tic disorder is a neuropsychiatric disorder characterized by involuntary movements or vocalizations. Previous studies utilizing diffusion-weighted imaging to explore white-matter alterations in tic disorders have reported inconsistent results regarding the affected tracts. We aimed to address this gap by employing a novel tractography technique for more detailed analysis. Methods: We analyzed MRI data from 23 children with tic disorders and 23 healthy controls using TRActs Constrained by UnderLying Anatomy (TRACULA), an advanced automated probabilistic tractography method. We examined fractional anisotropy (FA), radial diffusivity (RD), axial diffusivity, and mean diffusivity in 42 specific significant white matter tracts. Results: Our findings revealed notable differences in the children with tic disorders compared to the control group. Specifically, there was a significant reduction in FA in the parietal part and splenium of the corpus callosum and the left corticospinal tract. Increased RD was observed in the temporal and splenium areas of the corpus callosum, the left corticospinal tract, and the left acoustic radiation. A higher mean diffusivity was also noted in the left middle longitudinal fasciculus. A significant correlation emerged between the severity of motor symptoms, measured by the Yale Global Tic Severity Scale, and FA in the parietal part of the corpus callosum, as well as RD in the left acoustic radiation. Conclusion: These results indicate a pattern of reduced interhemispheric connectivity in the corpus callosum, aligning with previous studies and novel findings in the diffusion indices changes in the left corticospinal tract, left acoustic radiation, and left middle longitudinal fasciculus. Tic disorders might involve structural abnormalities in key white matter tracts, offering new insights into their pathogenesis. [ABSTRACT FROM AUTHOR]

TOURETTE syndrome , *TIC disorders , *PSYCHOGENIC nonepileptic seizures - Abstract
Background Objective Methods Results Conclusions The occurrence of tics is the main basis for the diagnosis of Gilles de la Tourette syndrome (GTS). Video‐based tic assessments are time consuming.The aim was to assess the potential of automated video‐based tic detection for discriminating between videos of adults with GTS and healthy control (HC) participants.The quantity and temporal structure of automatically detected tics/extra movements in videos from adults with GTS (107 videos from 42 participants) and matched HCs were used to classify videos using cross‐validated logistic regression.Videos were classified with high accuracy both from the quantity of tics (balanced accuracy of 87.9%) and the number of tic clusters (90.2%). Logistic regression prediction probability provides a graded measure of diagnostic confidence. Expert review of about 25% of lower‐confidence predictions could ensure an overall classification accuracy above 95%.Automated video‐based methods have a great potential to support quantitative assessment and clinical decision‐making in tic disorders.

Background: Sensory symptoms linked to tic disorder (TD) are challenging to quantify via self- or parent-reported measures. The current study aimed to develop a novel observer-rated semi-structured interview, namely, the Sensory Phenomenon Assessment Scale (SPAS), to aid clinical evaluation on symptoms of TD among children. Methods: To test its psychometric properties, tic, premonitory urge (PU), and obsessive-compulsive symptoms (OCS) were also assessed in 223 children via the Yale Global Tic Severity Scale (YGTSS), the Premonitory Urge for Tic Scale (PUTS), and the Children's Yale-Brown Obsessive-Compulsive Scale (CYBOCS). Factor analysis and internal consistency test were carried out using data from TD-diagnosed individuals. Results: Good internal consistency and test-retest reliability were observed. Criterion validity was established by significant correlations between the PUTS, the YGTSS, the CY-BOCS, and scores of the SPAS. Factor analyses supported a single-factor model of the SPAS, in which the five items each showed a factor loading above 0.6. Conclusion: This study demonstrated that the SPAS is reliable and valid and, thus, can serve as a good and concise measure of clinical symptoms among children and adolescents with TD.

We describe the implementation and evaluation of an online psychoeducation group for young people experiencing functional tic-like behaviours (FTLBs) – a type of functional neurological disorder (FND). Across six groups, 50 participants completed pre- and post-group goal-based outcomes (GBOs) and 36 participants completed service-user feedback, which gathered qualitative and quantitative data about participants experiences of the group. Young people and their parents reported significant improvement in their GBOs following the group and increased knowledge and confidence in managing FTLBs. The findings highlight that virtual psychoeducation group intervention is an acceptable and effective first step in treatment of young people with FTLBs. We discuss implications for future intervention development.

TIC disorders , *TOURETTE syndrome , *VOICE disorders , *MOVEMENT disorders , *INFLAMMATION - Abstract
The etiology of tic disorders (TDs) is not precisely known, although several lines of evidence suggest involvement of the immune system in pathogenesis. Here, we aimed to determine the expression levels of pro-inflammatory and anti-inflammatory cytokines in children with TD and compare them with those of healthy controls. Furthermore, we also evaluated their association with clinical variables in the TD group. Within the study period, 88 children with tic disorders and 111 healthy control children were enrolled. Most children with tic disorders were diagnosed with Tourette's disorder (n = 47, 53.4%) or persistent motor tic disorder (n = 39, 44.3%), while the remainder (n = 2, 2.3%) were diagnosed with persistent vocal tic disorder. We found that children with tic disorders had significantly elevated levels of IL-1β, TNF-α, IL-6 and IL-4 expression, while we detected lower expression levels of IL-17 in children with tic disorders. Our findings provide a molecular landscape of cytokine expression in children with TD, which may suggest a proinflammatory state not affected by the presence of comorbidity and symptom severity. Delineating the contribution of alterations in the immune system to the pathogenesis of tic disorders may pave the way for better therapeutic interventions. [ABSTRACT FROM AUTHOR]

Co-occurring psychiatric conditions are very common in tic disorders and Tourette syndrome. These additional symptoms are often detrimental to quality of life and may impact upon the implementation and efficacy of evidence-based behavioural therapies (BT) for tics. Combining a review of the available literature, relevant theory, and expert clinical practice, we present a guideline for implementing behavioural and psychosocial interventions when common comorbidities are present. These include attention-deficit hyperactivity disorder (ADHD), obsessive–compulsive disorder (OCD), anxiety, disruptive behaviour, autism spectrum disorder (ASD) and depression. Practical recommendations are provided for assessment, formulation and management of specific and multiple comorbidities in BT for both children and adults. Despite comorbidities being common in tic disorders, few studies have comprehensively addressed how they may influence the efficacy or implementation of existing therapies or how such treatments may need to be modified or sequenced. We outline recommendations for future research, including randomised control trials of BT for those with specific or multiple comorbidities, as well as adequately powered sub-group analyses within larger scale trials or naturalistic study designs. Transdiagnostic models of psychiatric disorders and treatment, including modular cross-diagnostic therapies, which recognise the dimensionality of psychiatric disorders are also highlighted as an important focus in treatment development in tic disorders.

TOURETTE syndrome , *PSYCHOTHERAPY , *DISEASE complications , *TIC disorders , *AFFECTIVE disorders - Abstract
In Tourette syndrome (TS), apart from multiple motor and vocal tics, there are often myriads of associated conditions apparently similar to attention-deficit-hyperactivity-disorder (ADHD), obsessive-compulsive-disorder (OCD), mood-and-conduct disorder, learning difficulties, etc. On the other hand, tic disorders often occur as co-morbidity with many neurodevelopmental disorders such as ADHD, OCD and mood disorders, and pharmacotherapy of these behavioral conditions may worsen the tics. So, the confusion lies whether to separately code and manage the different neurodevelopmental disorders or assume an umbrella construct of "TS-plus," as suggested by some researchers. In this background, we share three cases of children and adolescents having multiple tics with mixed behavioral presentations of ADHD/OCD/mood disorders that created a lot of diagnostic dilemma and treatment-related complications in prior psychiatric consultations. They were finally diagnosed as "TS-plus" and managed with low-dose-risperidone-mono-pharmaco-therapy and psychological interventions. In conclusion, psychiatrists should be vigilant for Tourette-syndrome while handling children with repetitive motor behaviors along with hyperactivity, obsession-compulsion, mood-conduct, etc. Assumption of an umbrella-construct approach of "TS-plus" may be beneficial in limiting the number of diagnosis and their separate pharmacotherapy, which may worsen the clinical scenario.

Behavior therapy is a well-established and empirically supported treatment for tic disorders (TDs). However, concerns have been expressed about the negative effects of behavioral interventions, such as tic worsening, tic substitution, and excessive effort. This study explored perceived negative effects of tic management strategies in adults with TDs and predictors of these experiences. Participants (N = 72) completed semi-structured interviews 11 years after receiving behavior therapy or supportive therapy in a randomized clinical trial. We examined responses to interview questions about managing tics and predictors of reported negative effects. Most participants did not experience tic worsening (84%) or tic substitution (75%) from tic management strategies. The majority felt they could manage tics while participating in their environment (87%) and did not report life interference from tic management (77%). About half (45%) felt less present when managing tics. Treatment non-responders in the original trial were more likely to report negative effects of tic management strategies. No differences in reported negative consequences were found between those who received behavior therapy versus supportive therapy, suggesting that behavior therapy specifically does not lead to such adverse effects. These findings could reduce misconceptions about behavior therapy for TDs and enhance its acceptability and utilization. [ABSTRACT FROM AUTHOR]

The regular behavior of the pulsations of high-amplitude δ Sct (HADS) stars gives a greater chance to investigate the interiors of stars. We analyzed seven HADS stars showing peak-to-peak amplitudes of more than 0.3 mag that were newly observed by TESS. We obtained that TIC 374753270, TIC 710783, and TIC 187386415 pulsate in fundamental radial mode; also, TIC 130474019 and TIC 160120432 show double radial modes. On the other hand, TIC 148357344 and TIC 278119167 demonstrate triple-mode behavior. Our analysis shows that these seven stars are close to the red edge of the (inside) instability strip in the Hertzsprung–Russell diagram. The fundamental mode of these seven targets follows the period–luminosity (PL) relation for δ Sct stars. However, TIC 278119167 deviates slightly from the fundamental PL relation. The double-mode and triple-mode HADS stars (TIC 130474019, TIC 160120432, TIC 148357344, and TIC 278119167) are in agreement with the period ratio ranges (fundamental to first and second overtones). Using the information of 176 HADS stars (Netzel and Smolec), we find a scaling relation ( [ Fe / H ] ∝ log (M 7.95 ± 0.15 L − 1.83 ± 0.11 P 0 0.79 ± 0.14 T eff 0.047 ± 0.02 )) between the metallicity ([Fe/H]) and mass (M), luminosity (L), effective temperature (T eff), and the fundamental period (P0). We estimate the metallicity of the seven newly identified HADS stars ranging from −0.62 to 0.37 dex. [ABSTRACT FROM AUTHOR]

This study aimed to understand the longitudinal relationship between psychosocial stress with tic exacerbation in children with Tourette syndrome (TS) and chronic tic disorder. Consecutive ratings of tic severity as well as child and parental reports of psychosocial stress were obtained for 373 children (296 males, 77 females; mean age 9y 5mo; SD 3y 3mo) with TS and chronic tic disorder between January 2018 and December 2020. The Yale Global Tic Severity Scale (YGTSS) global severity score, total tic score, and impairment rating were calculated. The stressful events and YGTSS measurements were used and treated as time-varying variables in the analyses. Models that controlled for non-independence among the repeated observations using a random intercept and random slope model were employed. Each participant was treated as a random factor in the modelling. Family-related stress, personal relationship stress and school-related stress were independently associated with increasing YGTSS global severity, total tic score, and impairment rating over time. An increased number of stressful events were associated with increased severity of tics. Family, personal relationships, and school-related stress were consistently associated with the exacerbation of tics. Managing these stressful events is important in the treatment of TS and chronic tic disorder. [ABSTRACT FROM AUTHOR]

A total of 25 studies were examined which highlighted children and adolescents with a tic disorder commonly met the criteria for a clinical anxiety disorder. While tic severity was found to be associated with higher levels of symptoms of anxiety in both children and adolescents with Tourette Syndrome (TS) or Chronic Tic Disorder (CTD), even higher levels of anxiety have been found in individuals who had an additional co-occurring diagnosis. For example, the diagnosis of having a tic disorder with OCD was more frequently associated with internalising disorders (e.g., anxiety, depressive, and somatic symptoms), whereas a diagnosis of a tic disorder and ADHD was commonly associated with externalising disorders (e.g., impulsivity disruptive conduct, substance use, and other addictive behaviours). Further studies are needed to address gender differences in anxiety, as anxiety is likely to be more prevalent in females with a tic disorder compared to both males and those with a later age of onset of tics. This review highlights the benefits of routinely screening for anxiety in children and adolescents with tics disorders, as well as the need for further considerations on how current treatments could be modified to help with anxiety and co-occurring diagnoses.

Abstract Background Oral aripiprazole exhibits favorable clinical efficacy and safety in the suppression of tics in children and adolescents with tic disorders. This study aims to evaluate and compare the cost-effectiveness of high-dose and low-dose aripiprazole in children and adolescents with tic disorders from the perspective of the Chinese healthcare system. Methods A questionnaire survey was conducted on 146 patients with tic disorders, of whom 144 completed EQ-5D-Y and YGTSS. Four models were built to convert YGTSS onto EQ-5D-Y utility using two mapping algorithms. We constructed a decision tree model containing efficacy and safety to compare the cost-effectiveness of high-dose and low-dose aripiprazole based on our mapping function. Results The GLM with model 1 (YGTSS total tic scores) was selected as the preferred function in our decision tree model. The base case cost-effectiveness analysis showed that compared to low-dose aripiprazole, high-dose aripiprazole improves effectiveness by 0.001QALYs and increases the overall cost by $197.99, resulting in an ICER of $174339.22 per QALY, which exceeds three times the gross domestic product per capita. Hence, high-dose aripiprazole is not likely to be a cost-effective option for child patients with tic disorders. One-way sensitivity analysis and probabilistic sensitivity analysis showed that these results is robust. Conclusion On the basis of currently available data, low-dose aripiprazole may be a safe, effective, and economical dosage for children and adolescents with tic disorders. Limitations The main limitation of our study is the lack of utility directly used for cost-effectiveness analysis. We obtained the utility of patients with tic disorders indirectly by the mapping function. This may introduce some bias and uncertainty. And it is a limitation to use the direct medical costs of Germany in our model. Although we converted it to the equivalent value of China using purchasing power parities, caution should be exercised when interpreting the results of this study.

Abstract The etiology of tic disorders (TDs) is not precisely known, although several lines of evidence suggest involvement of the immune system in pathogenesis. Here, we aimed to determine the expression levels of pro-inflammatory and anti-inflammatory cytokines in children with TD and compare them with those of healthy controls. Furthermore, we also evaluated their association with clinical variables in the TD group. Within the study period, 88 children with tic disorders and 111 healthy control children were enrolled. Most children with tic disorders were diagnosed with Tourette’s disorder (n = 47, 53.4%) or persistent motor tic disorder (n = 39, 44.3%), while the remainder (n = 2, 2.3%) were diagnosed with persistent vocal tic disorder. We found that children with tic disorders had significantly elevated levels of IL-1β, TNF-α, IL-6 and IL-4 expression, while we detected lower expression levels of IL-17 in children with tic disorders. Our findings provide a molecular landscape of cytokine expression in children with TD, which may suggest a proinflammatory state not affected by the presence of comorbidity and symptom severity. Delineating the contribution of alterations in the immune system to the pathogenesis of tic disorders may pave the way for better therapeutic interventions.

BackgroundComprehensive Behavioral Intervention for Tics (CBIT) is a first-line treatment for tic disorders that aims to improve controllability over tics that an individual finds distressing or impairing. However, it is only effective for approximately half of patients. Supplementary motor area (SMA)-directed neurocircuitry plays a strong role in motor inhibition, and activity in this region is thought to contribute to tic expression. Targeted modulation of SMA using transcranial magnetic stimulation (TMS) may increase CBIT efficacy by improving patients' ability to implement tic controllability behaviors.MethodsThe CBIT + TMS trial is a two-phase, milestone-driven early-stage randomized controlled trial. The trial will test whether augmenting CBIT with inhibitory, non-invasive stimulation of SMA with TMS modifies activity in SMA-mediated circuits and enhances tic controllability in youth ages 12-21 years with chronic tics. Phase 1 will directly compare two rTMS augmentation strategies (1 Hz rTMS vs. cTBS) vs. sham in N = 60 participants. Quantifiable, a priori "Go/No Go Criteria" guide the decision to proceed to phase 2 and the selection of the optimal TMS regimen. Phase 2 will compare the optimal regimen vs. sham and test the link between neural target engagement and clinical outcomes in a new sample of N = 60 participants.DiscussionThis clinical trial is one of few to date testing TMS augmentation of therapy in a pediatric sample. The results will provide insight into whether TMS is a potentially viable strategy for enhancing CBIT efficacy and reveal potential neural and behavioral mechanisms of change.Trial registrationClinicalTrials.gov NCT04578912 .

Abstract Background The Premonitory Urge for Tics Scale (PUTS) is a common self-report measure of premonitory urges for patients with tic disorders. This study aims to evaluate the Chinese version of the PUTS (PUTS-C) and to explore its association with psychiatric symptoms in Chinese children diagnosed with tic disorders. Methods The psychometric evaluation involved 204 outpatients with tic disorders, aged 7–16 years, who were divided into two age groups: (7–10 years, n = 103; 11–16 years, n = 95). Results The PUTS-C demonstrated good internal consistency (McDonald’sω = 0.84) and two-week test-retest reliability (0.76). We observed a statistically significant correlation between the total PUTS-C score and various Yale Global Tic Severity Scale (YGTSS) subscales and total tic severity scores. The PUTS-C score also showed significant correlations with the Children Yale-Brown Obsessive Compulsive Scale (CY-BOCS), Screening Child Anxiety-Related Emotional Disorders (SCARED), and Children’s Depression Inventory (CDI). Notably, premonitory urges independently predicted tic severity, beyond the influence of comorbid symptoms. A two-factor structure of the PUTS-C was identified in the total sample through factor analysis. Conclusions The PUTS-C possesses acceptable validity and good reliability. It appears that premonitory urges in Chinese patients with tic disorders are associated with obsessive-compulsive symptoms, anxiety, and depression, but can independently predict tic severity. Specific PUTS-C factors possibly related to motor and vocal tics. Future research should continue to investigate age-related differences and the association with tics and other sensory symptoms.

Abstract Objective To explore the relationship between body mass index (BMI ) and the severity of tic disorders (TDs) in children 6–14 years old. Methods A total of 86 children diagnosed with TDs in a hospital between Jan. 2023 and Sept. 2023 were collected by convenient sampling method, and the general data and TD-specific data were collected and analyzed. Results Univariate analysis showed that patients with different Yale Global Tic Severity Scale (YGTSS) grades had statistically significant differences in age, BMI, residence, snacking pattern, weekly physical exercise frequency, weekly physical exercise time, and proportion of cesarean birth. Multiple linear regression analysis showed that the YGTSS score grades were related to BMI, snacking pattern, and cesarean birth of the patients. Correlation analysis revealed a positive correlation between BMI grades and the YGTSS score grades, with a higher BMI indicating more severe TDs. Predictive value evaluation showed that BMI, snacking pattern, and cesarean birth had predictive values for TD severity, and the highest value was found in the combined prediction. Conclusion BMI, snacking pattern, and cesarean birth are of predictive values for the severity of TDs. In addition, BMI is positively correlated with the severity of TDs, and a higher BMI suggests more severe TDs.
