Abstract
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
BACKGROUND Motor and vocal tics are the main symptom of Gilles de la Tourette-syndrome (GTS). A particular complex vocal tic comprises the utterance of swear words, termed coprolalia. Since taboo words are socially inappropriate, they are normally suppressed by people, which implies cognitive control processes. METHOD To investigate the control of the unintentional pronunciation of taboo words and the associated processes of conflict monitoring, we used the "Spoonerisms of Laboratory Induced Predisposition" (SLIP) paradigm. Participants read multiple inductor word pairs with the same phonemes, followed by pronouncing a target pair with inverse phonemes. This led to a conflict between two competing speech plans: the correct word pair and the word pair with inverted phonemes. Latter speech error, a spoonerism, could result in a neutral or taboo word. We investigated 19 patients with GTS and 23 typically developed controls (TDC) and measured participants' electroencephalography (EEG) during the SLIP task. RESULTS At the behavioral level less taboo than neutral word spoonerisms occurred in both groups without significant differences. Event-related brain potentials (ERP) revealed a difference between taboo and neutral word conditions in the GTS group at the midline electrodes in a time range of 250-400 ms after the speech prompt, which was not found in the TDC group. The extent of this effect depended on the number of inductor word pairs, suggesting an increasing level of cognitive control in the GTS group. CONCLUSION The differences between taboo and neutral word conditions in patients with GTS compared to TDC suggest an altered recruitment of cognitive control processes in GTS, likely enlisted to suppress taboo words.

Abstract
BACKGROUND Tourette syndrome (TS) tics are typically quantified using "paper and pencil" rating scales that are susceptible to factors that adversely impact validity. Video-based methods to more objectively quantify tics have been developed but are challenged by reliance on human raters and procedures that are resource intensive. Computer vision approaches that automate detection of atypical movements may be useful to apply to tic quantification. OBJECTIVE The current proof-of-concept study applied a computer vision approach to train a supervised deep learning algorithm to detect eye tics in video, the most common tic type in patients with TS. METHODS Videos (N = 54) of 11 adolescent patients with TS were rigorously coded by trained human raters to identify 1.5-second clips depicting "eye tic events" (N = 1775) and "non-tic events" (N = 3680). Clips were encoded into three-dimensional facial landmarks. Supervised deep learning was applied to processed data using random split and disjoint split regimens to simulate model validity under different conditions. RESULTS Area under receiver operating characteristic curve was 0.89 for the random split regimen, indicating high accuracy in the algorithm's ability to properly classify eye tic vs. non-eye tic movements. Area under receiver operating characteristic curve was 0.74 for the disjoint split regimen, suggesting that algorithm generalizability is more limited when trained on a small patient sample. CONCLUSIONS The algorithm was successful in detecting eye tics in unseen validation sets. Automated tic detection from video is a promising approach for tic quantification that may have future utility in TS screening, diagnostics, and treatment outcome measurement. © 2023 The Authors.

Abstract
Complex tics and obsessive or compulsive behaviour can be difficult to differentiate diagnostically. The majority of adult patients with Tourette syndrome report experiencing premonitory urges before tics. Some of these experiences have been linked to non-just-right experiences (NJRE), which are frequently reported by patients with obsessive-compulsive disorder or behaviours (OCD/OCB). We aimed to assess whether NJRE are more closely related to tics and tic-associated premonitory urges or whether they are more closely associated with OCD. A total of N = 111 patients (mean age = 34.77 + /-12.93; N = 37 female) with a confirmed diagnosis of Tourette syndrome completed the premonitory urges for tic disorders scale (PUTS), the revised non-just-right experiences scale (NJRE-QR), and questionnaires regarding their tic severity, and comorbid OCD/OCB. A multi-trait-multi-methods matrix was calculated to examine associations amongst scales measuring tic-related and OCB-related phenomena. The PUTS correlated overall higher with tic questionnaires than with OCD/OCB questionnaires. The NJRE correlated higher with OCD symptoms than with tic severity. The results indicate that non-just-right experiences are more closely associated with comorbid OCB than with tics in patients with Tourette syndrome.

Abstract
AIMS Tourette syndrome (TS) is a neurological condition; its etiology is not yet fully understood. Cognitive behavioural therapy with habit reversal training is the recommended first-line treatment, but is not effective in all patients. This is the first report examining the usefulness of decoupling, a behavioural self-help treatment originally developed for patients with body-focused repetitive behaviours, in a patient with TS. METHOD Patient P.Z. showed 10 motor and three vocal tics on the Adult Tic Questionnaire (ATQ) before treatment. He was taught decoupling by the first author. RESULTS The application of decoupling led to a reduction of P.Z.'s eye tics, which was one of his first and most enduring and severe tics. It was not effective for other areas. Quality of life and depression improved, which P.Z. attributed to the improvement of his tics. CONCLUSION Decoupling may be adopted as an alternative, when habit reversal training is not feasible. Future research, preferably using a controlled design with a large sample, may elucidate whether decoupling is only effective for tics relating to the eyes, the most common symptom in tic disorder/TS, or whether its effects extend to other symptoms.

Abstract
Persons with Tourette syndrome show altered social behaviours, such as echophenomena and increased personal distress in emotional situations. These symptoms may reflect an overactive mirror neuron system, causing both increased automatic imitation and a stronger tendency to share others' emotions. To test this, we measured the individual level of echophenomena with a video protocol and experimentally induced empathy for pain in 21 participants with Tourette syndrome and 25 matched controls. In the empathy for pain paradigm, pictures of hands and feet in painful or neutral situations were presented, while we measured participants' EEG and skin conductance response. Changes in somatosensory mu suppression during the observation of the pictures and pain ratings were compared between groups, and correlations were calculated with the occurrence of echophenomena, self-reported empathy and clinical measures. Our Tourette syndrome sample showed significantly more echophenomena than controls, but the groups showed no behavioural differences in empathic abilities. However, controls, but not patients with Tourette syndrome, showed the predicted increased mu suppression when watching painful compared to neutral actions. While echophenomena were present in all persons with Tourette syndrome, the hypothesis of an overactive mirror neuron system in Tourette syndrome could not be substantiated. On the contrary, the Tourette syndrome group showed a noticeable lack of mu attenuation in response to pain stimuli. In conclusion, we found a first hint of altered processing of others' emotional states in a brain region associated with the mirror neuron system.

Abstract
BACKGROUND Tics are intimately associated with premonitory urges (PU) but knowledge about urges is still limited, with small sample sizes often limiting the generalizability of findings. OBJECTIVES This study addressed the following open questions: (1) is tic severity associated with urge severity, (2) how common is relief, (3) which comorbidities are associated with urges, (4) are urges, tics, and comorbidities associated with lower quality of life, and (5) can complex and simple, motor and vocal tics be differentiated based on PU? METHODS N = 291 patients who reported a confirmed diagnosis of chronic primary tic disorder (age = 18-65, 24% female) filled out an online survey assessing demographic data, comorbid conditions, location, quality and intensity of PU, as well as quality of life. Every tic was recorded, and whether the patient experienced a PU, the frequency, intensity, and quality of that urge. RESULTS PU and tic severity were significantly associated, and 85% of urge-related tics were followed by relief. A diagnosis of attention deficit/hyperactivity disorder (ADHD) or depression, female gender, and older age increased the likelihood of experiencing PU, while more obsessive compulsive (OCD) symptoms and younger age were associated with higher urge intensities. PU, complex vocal tics, ADHD, OCD, anxiety, and depression were related to lower quality of life. Motor and vocal, complex and simple tics did not differ regarding PU intensity, frequency, and quality, or relief. CONCLUSIONS The results shed light on the relationship between PU, tics, comorbidities, age, gender, and quality of life in tic disorders.

Abstract
Median nerve stimulation (MNS) at 10–12 Hz was recently proposed as a treatment for Tourette syndrome and other chronic tic disorders (TS/CTD). We report on 31 participants ages 15–64 with TS/CTD in an open-label, comparative (within-group, several time points) study of MNS (ClinicalTrials.gov registration number NCT05016765). Participants were recruited from completers of a randomized controlled trial (RCT) of MNS and were given a transcutaneous electrical nerve stimulation (TENS) unit to use as desired for 12 Hz MNS for 4 weeks. Participants were instructed to complete surveys regarding tic symptoms and stimulation discomfort before and after stimulation, as well as twice daily when randomly prompted by text message. Participants also completed an extensive final survey. Twenty-seven participants completed the study. Median device use was 1.5 days per week and 50 min per day used. Tic frequency improved during MNS (mean improvement: 1.0 on a 0–5 scale, p < 0.001), as did tic intensity (mean improvement: 0.9, p < 0.001). Mean discomfort was mild (1.2 on a 3-point scale). In total, 21 participants (78%) planned to continue using the device. Participants’ results in this study did not correlate significantly with their results in the blinded RCT. We found MNS to improve tic frequency and intensity with minimal side effects.

Abstract
A prior study showed that rhythmic, but not arrhythmic, 12 Hz stimulation of the median nerve (MNS) entrained the sensorimotor cortex EEG signal and found that 10 Hz MNS improved tics in Tourette syndrome (TS). However, no control condition was tested, and stimulation blocks lasted only 1 min. We set out to replicate the TS results and to test whether tic improvement occurs by the proposed cortical entrainment mechanism. Preregistration was completed at ClinicalTrials.gov, under number NCT04731714. Thirty-two people with TS, age 15-64, completed two study visits with repeated MNS on and off blocks in random order, one visit for rhythmic and one for arrhythmic MNS. Subjects and staff were blind to order; a video rater was additionally blind to stimulation and to the order of visits and blocks. Rhythmic MNS at 10 Hz improved tics. Both rhythmic and arrhythmic 12 Hz MNS improved tic frequency, intensity, and urges, but the two treatments did not differ significantly. Participant masking was effective, and there was no carryover effect. Several participants described a dramatic benefit. Discomfort was minimal. There was no evidence that the MNS benefit persisted after stimulation ended. These results replicate the tic benefit from MNS but show that the EEG entrainment hypothesis cannot explain that benefit. Another electrophysiological mechanism may explain the benefit; alternatively, these data do not exclude a placebo effect.

Impulsivity and Attention in Obsessive Compulsive and Tic Disorders: Mismatch in Self-Report and Behavioural Data. J Clin Med 2023; 12:jcm12062277. [PMID: 36983278 PMCID: PMC10053998 DOI: 10.3390/jcm12062277] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2023] [Revised: 03/05/2023] [Accepted: 03/07/2023] [Indexed: 03/17/2023] Open
Abstract
Impulsivity is a multidimensional, cross-diagnostic behavioural construct that has been described in various psychiatric disorders including obsessive-compulsive disorder (OCD) and Tourette syndrome (TS). Different interpretations of results in the past have raised the question of heightened impulsivity as an explanatory model for self-described impulsive behaviour, especially in OCD. Our study included 16 patients with OCD, 14 patients with TS, and 28 healthy control subjects (HC). Self-assessed impulsivity was examined by the Barratt Impulsiveness Scale-11 (BIS-11), and the behavioural test used was the immediate and delayed memory task (IMT/DMT). Significantly heightened self-assessed impulsivity of the patient collective compared to HC could be observed in in only one dimension: lack of attention (χ2 (2) = 24.910, p < 0.001). Post-hoc tests were performed using Bonferroni adjusted alpha levels of 0.0167 per test (0.05/3) and revealed significantly higher scores in patients with OCD (M = 19.57, SD = 2.82), z = 4.292, p < 0.001 as with TS (M = 19.38, SD = 3.62), z = 3.832, p < 0.001 compared to HC (M = 13.78, SD = 3.18). In patients with OCD, correlations between the dimension of obsessive thoughts with a lack of attention in the form of first-order factor cognitive instability could be shown (n = 14, p = 0.024, rs = 0.599) while in patients with TS, tic symptomatology correlated significantly with second-order factor attentional impulsivity (n = 12, p = 0.027, rs = 0.635). In behavioural testing, no significant group differences could be observed either in impulsive behaviour (IMT: χ2 (2) = 4.709, p = 0.824; DMT: χ2 (2) = 0.126, p = 0.939) or in sustained attention (IMT: χ2 (2) = 0.388, p = 0.095; DMT: χ2 (2) = 0.663, p = 0.718). Heightened impulsivity as an explanatory model for the observed lack of attention, especially in patients with OCD, should be questioned and interpretation biases considered in the future. The necessity of a multidimensional approach to the research of impulsivity is underscored by our results.

Abstract
A prior study showed that rhythmic, but not arrhythmic, 12 Hz stimulation of the median nerve (MNS) entrained sensorimotor cortex EEG signal, and found that 10 Hz MNS improved tics in Tourette syndrome (TS). However, no control condition was tested and stimulation blocks lasted only 1 minute. We set out to replicate the TS results and to test whether tic improvement occurs by the proposed cortical entrainment mechanism. Thirty-two people with TS, age 15-64, completed two study visits with repeated MNS on and off blocks in random order, one visit for rhythmic and one for arrhythmic MNS. Subjects and staff were blind to order; a video rater was additionally blind to stimulation and to order of visits and blocks. Rhythmic MNS at 10 Hz improved tics. Both rhythmic and arrhythmic 12 Hz MNS improved tic frequency, intensity and urges without significant difference. Participant masking was effective and there was no carryover effect. Several participants described dramatic benefit. Discomfort was minimal. MNS benefit did not persist after the end of stimulation. These results replicate the tic benefit from MNS, but show that the EEG entrainment hypothesis cannot explain that benefit. Another electrophysiological mechanism may explain benefit; alternatively, these data do not exclude a placebo effect. Registration ClinicalTrials.gov , NCT04731714 .

Abstract
BACKGROUND Despite the known benefits of art therapy, there are a limited number of studies on art therapy for tic disorders. This pilot randomised controlled study investigated effects of art as a relaxation technique for tic disorders. METHODS Twenty-two children aged 7-9 years were randomly allocated to art intervention (n= 11) and control (n= 11) groups. Pre- and post-test measurements included the Yale Global Tic Severity Scale (YGTSS), Heart Rate Variability (HRV), and Hassles Scale for Children (HSC). RESULTS Art as relaxation significantly decreased the YGTSS total score, motor tic frequency, motor tic intensity, motor tic complexity, vocal tic complexity, and total daily stressors compared to the control group. The intervention group showed significantly greater physiological relaxation, as indicated by increases in HRV parameters. CONCLUSIONS Art appears to be an effective relaxation technique for tic disorders. Extensive research is necessary for rigorous examination of its effectiveness.

Abstract
In 2011 a working group of the European Society for the Study of Tourette Syndrome (ESSTS) has developed the first European assessment guidelines for Tourette syndrome (TS). Now, we present an updated version 2.0 of these European clinical guidelines for Tourette syndrome and other tic disorders, part I: assessment. Therefore, the available literature has been thoroughly screened, supplemented with national guidelines across countries and discussions among ESSTS experts. Diagnostic changes between DSM-IV and DSM-5 classifications were taken into account and new information has been added regarding differential diagnoses, with an emphasis on functional movement disorders in both children and adults. Further, recommendations regarding rating scales to evaluate tics, comorbidities, and neuropsychological status are provided. Finally, results from a recently performed survey among ESSTS members on assessment in TS are described. We acknowledge that the Yale Global Tic Severity Scale (YGTSS) is still the gold standard for assessing tics. Recommendations are provided for scales for the assessment of tics and psychiatric comorbidities in patients with TS not only in routine clinical practice, but also in the context of clinical research. Furthermore, assessments supporting the differential diagnosis process are given as well as tests to analyse cognitive abilities, emotional functions and motor skills.

Abstract
OBJECTIVE This study examined sleep disorders and sleep medication use rates, nighttime tics, and sleep and chronotype in relation to tic and co-occurring symptoms in adults with persistent tic disorders (PTDs), including Tourette's disorder (TD). METHODS One hundred twenty-five adult internet survey respondents rated sleep history, sleep, chronotype, tic severity, impairment, attention deficit hyperactivity disorder, obsessive-compulsive symptoms, anxiety, depression, and emotional and behavioral dyscontrol. RESULTS Bruxism, insomnia, tic-related difficulty falling asleep, and melatonin use were commonly endorsed. Sleep disturbance correlated with impairment, obsessive-compulsive symptoms, and emotional and behavioral dyscontrol. Eveningness correlated with vocal and total tic severity only in TD. Controlling for age and sex, age, impairment, and obsessive-compulsive symptoms predicted sleep disturbance, and age and tic severity predicted chronotype. CONCLUSIONS Impairment and obsessive-compulsive symptoms play a role in sleep disturbance in adults with PTDs, and may be intervention targets. Eveningness relates to tic severity, which may suggest the utility of interventions to advance chronotype.

Abstract
Objective In patients with Tourette syndrome and other primary tic disorders (PTDs), tics are typically preceded by premonitory urges (PUs). To date, only a few studies have investigated the location and frequency of PUs, and contrary to clinical experience, the results suggest that PUs are not located in the same anatomic region as the tics. This study aimed to further explore PU location and frequency in detail, differentiating the kind and complexity of the corresponding tics, in a large sample of patients with PTD. Methods A total of 291 adult (≥ 18 years) patients with a confirmed diagnosis of chronic PTD were included. The study was conducted online, assement included tics and the general characterization of PUs and a sophisticated body drawing for locating PUs. Results We found that PUs were located in the same body area as, or in direct proximity to, the corresponding tic. Most frequently, PUs were located in the face and at the head (62.1%). Compared with simple tics, complex (motor and vocal) tics were more often preceded by a PU; but there was no difference in PU frequency observed between motor tics and vocal tics. PUs were more often experienced at the front than at the back of the body (73% vs. 27%), while there was no difference between the right and left sides (41.6% vs. 41.3%). Conclusion The strong association between PU and tic location further supports the hypothesis that PUs represent the core of PTD. Accordingly, future therapies should focus on treating PUs to achieve greater tic reduction.

Abstract
Comprehensive Behavioral Intervention for Tics (CBIT) is considered a first-line therapy for tics. However, availability of CBIT is extremely limited due to a lack of qualified therapists. This study is a multicenter (n = 5), randomized, controlled, observer-blind trial including 161 adult patients with chronic tic disorders (CTD) to provide data on efficacy and safety of an internet-delivered, completely therapist-independent CBIT intervention (iCBIT Minddistrict®) in the treatment of tics compared to placebo and face-to-face (f2f) CBIT. Using a linear mixed model with the change to baseline of Yale Global Tic Severity Scale-Total Tic Score (YGTSS-TTS) as a dependent variable, we found a clear trend towards significance for superiority of iCBIT (n = 67) over placebo (n = 70) (−1.28 (−2.58; 0.01); p = 0.053). In addition, the difference in tic reduction between iCBIT and placebo increased, resulting in a significant difference 3 (−2.25 (−3.75; −0.75), p = 0.003) and 6 months (−2.71 (−4.27; −1.16), p < 0.001) after the end of treatment. Key secondary analysis indicated non-inferiority of iCBIT in comparison to f2f CBIT (n = 24). No safety signals were detected. Although the primary endpoint was narrowly missed, it is strongly suggested that iCBIT is superior compared to placebo. Remarkably, treatment effects of iCBIT even increased over time.

[PMID: 35990066 PMCID: PMC9388784 DOI: 10.3389/fpsyt.2022.914044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Accepted: 07/13/2022] [Indexed: 11/15/2022] Open
Abstract
OBJECTIVES Tic disorders (TDs) are complex neurological conditions characterized by involuntary, persistent vocalizations and motor movements called tics. Tics involve brief muscle movements and can impair many aspects of daily functioning and quality of life in patients - and their physical nature can cause pain. Understanding individuals' experiences of tic-related pain and pain management could help explore this under-researched area and identify additional support needs for this population. The aim of this study was to investigate experiences of pain and use of pain management techniques in people with tic disorders. METHODS An online survey consisting of multiple choice and open-ended questions exploring experiences of tic-related pain, help-seeking behavior for tic-related pain, and use of pain relief techniques for tic-related pain, was circulated online via international Tourette syndrome patient associations, and one online support group for Tourette syndrome. The online survey was open to adults (≥16 years) with self-reported tics. Open-ended questions were analyzed using thematic analysis. RESULTS One hundred eighty-one participants (16-71 years; 58.0% female) from 18 countries completed the online survey. Several aspects of tics were associated with pain, including the physical effort of motor tics (n = 177, 97.8%), repetitive tics (n = 141, 77.9%) and the consequences of tics (n = 131, 72.4%). Nearly two-thirds (n = 118, 64.6%) had sought professional help for tic-related pain. Distraction techniques (n = 126, 69.6%), taking pain relief medication (n = 125, 69.1%) and altering tics (n = 111, 61.3%) were the most commonly-reported methods used to relieve and cope with tic-related pain. Thematic analysis found an interrelated complex relationship between participants' tics, pain, and pain management techniques, reflected in four themes: the "tic-pain" cycle, the impact of pain, the importance of support, and the perceived successfulness of pain management techniques. CONCLUSIONS Tic-related pain was reported to have a significant physical and psychological impact which impacted aspects of daily living in people with tic disorders. The findings add to limited research suggesting tic-related pain is a dominant issue for individuals with tic disorders, potentially impacting upon their quality of life. Increased understanding of tic-related pain and its influence may be helpful in the long-term management of tic disorders, both in terms of clinical management and patients' self-management.

Abstract
Introduction
Tourette syndrome (TS) is a complex neurodevelopmental
disorder characterized by chronic motor and vocal tics. While consistently
effective treatment is lacking, evidence indicates that the modulation of
endocannabinoid system is potentially beneficial. Lu AG06466 (previously
ABX-1431) is a highly selective inhibitor of monoacylglycerol lipase, the
primary enzyme responsible for the degradation of the endocannabinoid ligand
2-arachidonoylglycerol. This exploratory study aimed to determine the effect of
Lu AG06466 versus placebo on tics and other symptoms in patients with TS.
Methods
In this phase 1b cross-over study, 20 adult patients with TS on
standard-of-care medications were randomized to a single fasted dose of Lu
AG06466 (40 mg) or placebo in period 1, followed by the other treatment
in period 2. The effects on tics, premonitory urges, and psychiatric
comorbidities were evaluated using a variety of scaled approaches at different
time points before and after treatment.
Results
All scales showed an overall trend of tic reduction, with two out
of three tic scales (including the Total Tic Score of the Yale Global Tic
Severity Score) showing a significant effect of a single dose of Lu AG06466
versus placebo at various timepoints. Treatment with Lu AG06466 resulted in a
significant reduction in premonitory urges versus placebo. Single doses of Lu
AG06466 were generally well-tolerated, and the most common adverse events were
headache, somnolence, and fatigue.
Conclusion
In this exploratory trial, a single dose of Lu AG06466 showed
statistically significant positive effects on key measures of TS symptoms.

Abstract
Individuals with Tourette's Disorder and Persistent Tic Disorders (TD) often experience premonitory urges-aversive sensations that precede tics and are relieved by tic expression. Given its role in the neurobehavioral model of TD, understanding factors that influence premonitory urges and associated relief can advance understanding of urge phenomenology and optimize treatments for individuals with TD. This study examined whether the novel construct of urge intolerance-difficulty tolerating premonitory urges-predicted tic severity and tic-related disability. Participants included 75 youth with TD and their caregivers. Assessments characterized tic severity, premonitory urge, distress tolerance, internalizing symptoms, and tic-related disability. Structural equation modeling revealed that higher levels of urge intolerance predicted greater levels of tic-related disability. Furthermore, the relationship between urge intolerance and tic-related disability was more robust for youth with clinically-elevated levels of internalizing symptoms. While further investigation is needed, urge intolerance represents a promising treatment target to improve tic-related disability in youth with TD.

BACKGROUND Modulation of the endocannabinoid system via monoacylglycerol lipase inhibition with Lu AG06466 (formerly known as ABX-1431) has previously been shown to reduce tics in patients with Tourette syndrome. OBJECTIVE The aim of this study was to evaluate the efficacy and safety of Lu AG06466 in reducing tics, premonitory urges, and comorbidities in patients with Tourette syndrome. METHODS This was a 12-week, multicenter, randomized, placebo-controlled, double-blind clinical trial of Lu AG06466 given at two dose levels in 49 adults with Tourette syndrome. RESULTS Both treatment groups showed improvement on the Total Tic Score of the Yale Global Tic Severity Scale; the mean (95% CI) treatment difference at week 8 of 3.0 (0.1, 5.9) (P = 0.043) favored placebo. No significant differences were seen for other endpoints assessing changes in tic severity, premonitory urges, quality of life, and common psychiatric comorbidities. Treatment with Lu-AG06466 was generally safe. CONCLUSIONS There was no evidence that Lu AG06466 has efficacy in suppressing tics. © 2021 The Authors.

Randomized double-blind sham-controlled trial of thalamic versus GPi stimulation in patients with severe medically refractory Gilles de la Tourette syndrome. Brain Stimul 2021; 14:662-675.

Abstract
BACKGROUND There are still no sufficient data regarding the use of deep brain stimulation (DBS) in Gilles de la Tourette syndrome (GTS) and no agreement on optimal target. OBJECTIVE To compare efficacy and safety of bilateral DBS of thalamus (centromedian-ventro-oral internus, CM-Voi) versus posteroventral lateral globus pallidus internus (pvl GPi)) versus sham stimulation, and baseline in severe medically refractory GTS. METHODS In this randomized double-blind sham stimulation-controlled trial (RCT), 10 patients (3 women, mean age = 29.4 ± 10.2 SD, range 18-47) underwent three blinded periods each lasting three months including (i) sham, (ii) pvl GPi (on-GPi), and (iii) thalamic stimulation (on-thal) followed by an open uncontrolled long-term follow-up (up to 9 years) with individually determined target and stimulation settings. RESULTS Nine patients completed the RCT. At group level, on-GPi - but not on-thal - resulted in a significant tic reduction compared to baseline, but had no effect on premonitory urges and psychiatric comorbidities. Direct comparisons of targets resulted in inconsistent or negative (compared to sham) findings. During follow-up, we found no improvement of tics, comorbidities, and quality of life at group level, however, single patients benefitted continuously from thalamic DBS. At last follow-up 89.9 months (mean) after surgery, 50% of patients had discontinued DBS. Hardware infections occurred in 3/10 patients. CONCLUSION Our data suggest that the initial effect of pvl GPi DBS is superior to thalamic (CM-Voi) DBS. While half of the patients discontinued treatment, single patients benefitted from thalamic DBS even after years. It is likely that outcome is influenced by various factors beyond the mere change in tic severity.

Abstract
Background Little is known about the lived experiences of individuals with tic disorders when driving vehicles or trying to obtain a driving license. Objective To survey the driving‐related experiences of adults with tic disorders. Methods A global survey was disseminated via social media, international patient organizations, and experts between April 27, 2020 and July 20, 2020. Results Participants were 228 adult individuals self‐reporting a confirmed diagnosis of Tourette syndrome or chronic tic disorder. Of these, 183 (87.7%) had a driver's license. A minority (9%) reported that they had found it hard to pass the driving test. Tics only interfered with driving “a bit” (58.5%) or “not at all” (33%). A majority of participants reported being able to suppress their tics (39.5%) or that their tics are unchanged (28.5%) while driving. Nearly half of the participants (46.5%) had been involved in accidents, but only a negligible percentage (3.2%) considered that these were linked to the tics. Participants without a driver's license (n = 28, 12.3%) reported significantly more severe tics, compared to those with a license. The majority of these (60.7%) identified their tics as the main reason for not having a license and 64.3% said that they would like to receive support to obtain one. Conclusions The majority of surveyed participants with chronic tic disorders reported minimal difficulties with driving. However, a non‐negligible minority of more severe cases struggle with driving or refrain from driving altogether and would benefit from additional support. The results have implications for clinicians and vehicle licensing agencies.

Yale Global Tic Severity Scale (YGTSS): Psychometric Quality of the Gold Standard for Tic Assessment Based on the Large-Scale EMTICS Study. Front Psychiatry 2021; 12:626459.

Abstract
The Yale Global Tic Severity Scale (YGTSS) is a clinician-rated instrument considered as the gold standard for assessing tics in patients with Tourette's Syndrome and other tic disorders. Previous psychometric investigations of the YGTSS exhibit different limitations such as small sample sizes and insufficient methods. To overcome these shortcomings, we used a subsample of the large-scale "European Multicentre Tics in Children Study" (EMTICS) including 706 children and adolescents with a chronic tic disorder and investigated convergent, discriminant and factorial validity, as well as internal consistency of the YGTSS. Our results confirm acceptable convergent and good to very good discriminant validity, respectively, indicated by a sufficiently high correlation of the YGTSS total tic score with the Clinical Global Impression Scale for tics (r s = 0.65) and only low to medium correlations with clinical severity ratings of attention deficit/hyperactivity symptoms (r s = 0.24), obsessive-compulsive symptoms (r s = 27) as well as internalizing symptoms (r s = 0.27). Internal consistency was found to be acceptable (Ω = 0.58 for YGTSS total tic score). A confirmatory factor analysis supports the concept of the two factors "motor tics" and "phonic tics," but still demonstrated just a marginal model fit (root mean square error of approximation = 0.09 [0.08; 0.10], comparative fit index = 0.90, and Tucker Lewis index = 0.87). A subsequent analysis of local misspecifications revealed correlated measurement errors, suggesting opportunities for improvement regarding the item wording. In conclusion, our results indicate acceptable psychometric quality of the YGTSS. However, taking the wide use and importance of the YGTSS into account, our results suggest the need for further investigations and improvements of the YGTSS. In addition, our results show limitations of the global severity score as a sum score indicating that the separate use of the total tic score and the impairment rating is more beneficial.

Abstract
Quantitative evaluation of tic disorders (TDs) is challenging as there are few objective indicators that can be used for the assessment of treatment outcomes. 18F-Fluorodeoxyglucose (FDG) is a radioactive tracer that is able to cross the blood-brain barrier and can be detected by positron emission tomography/CT (PET/CT). In the present study, it was hypothesized that FDG PET/CT scan can be applied to reflect the severity of tic symptoms in a rat TD model, where signals detected in the brain striatum can be used to evaluate the efficacy of tic treatment with traditional Chinese medicine (TCM). A rat model of TD was established by treatment with iminodipropionitrile. Rats were divided into the following four groups (n=10 each): i) Control; ii) TCM; iii) haloperidol; and iv) model only. Observations of stereotypic behavior in rats were subsequently scored and micro-PET/CT was used to evaluate the rate of FDG uptake. Stereotypy scores were found to be significantly higher (P<0.05) in the TD rat model (P<0.05) compared with those in control rats. Both stereotypy scores (P<0.05) and standardized FDG uptake values (SUV; P<0.05) were revealed to be significantly reduced in the TD model rats after treatment with TCM or haloperidol. SUV correlated positively with stereotypy score (R=0.926; P<0.05) and the SUV scores were found to be significantly different among control group, TCM group, haloperidol group and model only group (P<0.05). These data suggest that the application of FDG in the striatum can be used to evaluate the effectiveness of TCM treatment for TDs.

Abstract
OBJECTIVE The Yale Global Tic Severity Scale (YGTSS) is the most commonly used clinician-rated evaluation tool for Tourette syndrome (TS), with established reliability and validity. This study aims to determine whether the YGTSS is a valid parent-reported assessment in the TS population. DESIGN A prospective cohort study. SETTING A major medical centre in Taiwan. METHODS A total of 594 patients were enrolled. A revised traditional Chinese version of the YGTSS was made available to parents via Google docs. Parents were encouraged to complete the YGTSS the day before each outpatient clinic visit. At each visit, a paediatric neurology fellow also administered the YGTSS assessment. We investigated whether differences in scores between physicians and parents changed as the number of parent evaluations increased. The results of the physician assessments were also taken as the expert standard for evaluating the sensitivity and specificity of the parent-reported assessments was conducted for the same visit. RESULTS The differences in the YGTSS scores between participants and physicians were small. The mean difference in the total assessment score was 4.15 points. As the number of times the parent evaluation was performed increased, the difference between the parent and physician scores decreased. Discrimination of moderate-to-severe attacks was good using the parent-assessed YGTSS (area under the receiver operating characteristic curve, 0.858; 95% CI 0.839 to 0.876). The sensitivity for detecting a moderate-to-severe attack by YGTSS parent assessment was 79.7% (95% CI 76.6 to 82.8), and the specificity was 91.8% (95% CI 89.9 to 93.7). CONCLUSION The parent-reported YGTSS is a promising tool for TS assessment, demonstrating good discriminative ability for disease severity, with user precision increasing with experience.

Abstract
AIM To evaluate the effectiveness of a modified four-session Comprehensive Behavioral Intervention for Tics programme for decreasing tics in children and adolescents with Tourette's syndrome. BACKGROUND Comprehensive Behavioral Intervention for Tics programme has been shown to decrease tic severity. However, the lack of behaviour therapists in countries, such as in Taiwan, may preclude application of the standard eight-session, 10-week programme. DESIGN Randomized controlled study. METHODS Participants aged 6-18 years diagnosed with Tourette's syndrome or chronic tic disorder were recruited from February 2015 through September 2016. Participants in the control and intervention groups (N = 23 each) received the routine care (daily pyridoxine [50 mg] and psychoeducation). The intervention group received additional four behavioural intervention sessions over a 3-month period that included psychoeducation, habit reversal training, relaxation training, and education on tic relapse prevention. The outcome measures, Yale Global Tic Severity Scale scores, were assessed at before and after the completion of programme for both groups and again at 3 months follow-up for the intervention group. The effect of the intervention on severity scores was assessed using a generalized estimated equation. RESULTS Comparison of scores before and after intervention showed that the intervention significantly decreased the severity of total motor tics (B = -3.28, p < .01) and total tics (B = -5.86, p < .01) as compared with control treatment. YGTSS scores for the intervention group were lower at 3-month follow-up as compared with before treatment or immediately after treatment completion (total tics, p < .001). CONCLUSION The modified four-session Comprehensive Behavioral Intervention for Tics programme was more effective than routine care for decreasing tic severity in our cohort of 6- to 18-year olds. This improvement was maintained 3 months after intervention. IMPACT Healthcare providers, including nurses, in countries currently not adopting Comprehensive Behavioral Intervention for Tics programme should be made aware of the positive effects of this modified intervention for Tourette's syndrome.

Abstract
INTRODUCTION Although defined by the presence of tics, most patients with Gilles de la Tourette syndrome (TS) also suffer from different psychiatric disorders. While much is known about clinical characteristics of comorbidities such as attention deficit/hyperactivity disorder (ADHD), obsessive compulsive disorder (OCD), depression, and anxiety disorders, only very little is known about rage attacks. Most of this data is based on small studies in children. Until today no larger studies have been performed in adults with TS-most likely because of the lack of validated instruments. The aim of this study was to develop a new assessment and investigate rage attacks in a large sample of adults with TS and healthy individuals. MATERIALS AND METHODS Based on a parent questionnaire for children with TS, we generated 27 items for a revised version of a rage attack questionnaire (RAQ-R) and tested factor structure, internal consistency, as well as convergent and discriminant validity. We used an online survey and included 127 patients with TS and 645 control subjects. In addition to the RAQ-R, we used several other self-assessments to measure tic severity, quality of life, as well as several psychiatric symptoms including ADHD, OCD, depression, anxiety, and impulsivity. RESULTS Based on expert option and statistical analyses [including item-total correlation, skewness, inter-item correlation, and principal component analysis (PCA)], we performed an item reduction resulting in a final, 22-items version of the RAQ-R (range, 0-66). Investigating internal consistency, discriminant validity, test reliability, and factor structure, the RAQ-R demonstrated good to excellent quality criteria. As assessed by RAQ-R, rage attacks were significantly more common in patients with TS compared to controls (p < 0.001). Rage attacks could be clearly differentiated from the phenomenon of impulsivity. Although rage attacks occurred more often in individuals with ADHD, they were also found in patients with "TS only", independently from comorbid ADHD, impulsivity, and OCD. Rage attacks were found to significantly influence patients' quality of life. CONCLUSIONS Thus, from our data based on a large sample it is suggested that rage attacks represent a discrete comorbidity in adults with TS.

Abstract
This study assessed the psychometric properties of a parent-reported tic severity measure, the Parent Tic Questionnaire (PTQ), and used the scale to establish guidelines for delineating clinically significant tic treatment response. Participants were 126 children ages 9 to 17 who participated in a randomized controlled trial of Comprehensive Behavioral Intervention for Tics (CBIT). Tic severity was assessed using the Yale Global Tic Severity Scale (YGTSS), Hopkins Motor/Vocal Tic Scale (HMVTS) and PTQ; positive treatment response was defined by a score of 1 (very much improved) or 2 (much improved) on the Clinical Global Impressions - Improvement (CGI-I) scale. Cronbach's alpha and intraclass correlations (ICC) assessed internal consistency and test-retest reliability, with correlations evaluating validity. Receiver- and Quality-Receiver Operating Characteristic analyses assessed the efficiency of percent and raw-reduction cutoffs associated with positive treatment response. The PTQ demonstrated good internal consistency (α = 0.80 to 0.86), excellent test-retest reliability (ICC = .84 to .89), good convergent validity with the YGTSS and HM/VTS, and good discriminant validity from hyperactive, obsessive-compulsive, and externalizing (i.e., aggression and rule-breaking) symptoms. A 55% reduction and 10-point decrease in PTQ Total score were optimal for defining positive treatment response. Findings help standardize tic assessment and provide clinicians with greater clarity in determining clinically meaningful tic symptom change during treatment.

Abstract
Gilles de la Tourette syndrome (GTS) may involve cognitive inflexibility. A meta-analysis reveals GTS-related deficits on the Wisconsin Card Sorting Test. Card-sorting deficits are larger in children than in adults with GTS. Adults with GTS show electrophysiological signs of enhanced cognitive control. This change may underlie the normalization of cognitive flexibility in adult GTS.
Motor symptoms in Gilles de la Tourette syndrome (GTS) have been related to changes in frontostriatal brain networks. These changes may also give rise to alterations in cognitive flexibility. However, conclusive evidence for altered cognitive flexibility in patients with GTS is still lacking. Here, we meta-analyzed data from 20 neuropsychological studies that investigated cognitive flexibility in GTS using the Wisconsin Card Sorting Test (WCST). Results revealed medium-sized GTS-related performance deficits, which were significantly modulated by age: Whilst being substantial in children and adolescents with GTS, WCST deficits seem to dissolve in adult patients with GTS. This age-related normalization of WCST performance might result from the compensatory recruitment of cognitive control in adult patients with GTS. We addressed this possibility by examining neural correlates of proactive and reactive cognitive control in an event-related potential (ERP) study. We analyzed cue- and target-locked ERPs from 23 adult patients with GTS and 26 matched controls who completed a computerized version of the WCST. Compared to controls, patients with GTS showed a marked increase in parietal cue-locked P3 activity, indicating enhanced proactive cognitive control. We conclude that the additional recruitment of proactive cognitive control might ensure flexible cognitive functioning in adult patients with GTS.

Abstract
Acceptance and commitment therapy (ACT) is a function-based treatment that can be applied to multiple clinical concerns where psychological inflexibility is a mediating issue. This case study describes the use of ACT in combination with habit reversal training for a man with a primary concern of Tourette’s disorder and a secondary concern of chewing tobacco use. Large reductions were seen in the primary outcomes of motor and vocal tics (measured by behavioral tracking and a semi-structured assessment) and chewing tobacco use after 19 individual sessions. Furthermore, increases in psychological flexibility and quality of life and decreases in overall symptomatology were seen at posttreatment. This article conceptualizes this case from a cohesive theory, describes the details of the presenting concerns, and explains the treatment used and treatment outcomes. A description of barriers and suggestions for further treatment and research are also presented.
