Mazur-Lainé E, Soubata H, Leclerc JB, Blanchet PJ, O’Connor KP, Lavoie ME. Impacts of ADHD Symptomatology on the Response to Cognitive-Behavioural Therapy with Gilles de la Tourette Syndrome Patients. J Clin Med 2024; 13:2975. [PMID: 38792517 PMCID: PMC11122476 DOI: 10.3390/jcm13102975] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2024] [Revised: 05/10/2024] [Accepted: 05/16/2024] [Indexed: 05/26/2024] Open
Abstract
(1) Background: Gilles de la Tourette Syndrome (TS) is a neurodevelopmental disorder characterized by motor and vocal tics. Attention deficit and hyperactivity disorder (ADHD) is a common comorbidity of TS that adds further impairment. Cognitive-behavioural therapy (CBT) has shown efficacy in treating tics, yet its effectiveness in individuals with TS and comorbid ADHD remains unclear. Also, it is suggested that ADHD characteristics like executive dysfunction and inattention could hinder the response to CBT. This study aims to compare the response to CBT for tics and its maintenance six months post-therapy among TS individuals with and without ADHD symptoms. (2) Methods: In this study, 55 TS participants who completed 14-week CBT for tics were split into high (TS+) or low (TS-) ADHD symptomatology groups. Outcomes were evaluated using the Yale Global Tic Severity Scale (YGTSS) regarding global tic severity and motor and vocal tic frequency post-CBT and at a 6-month follow-up. (3) Results: No significant group difference was found regarding improvements post-CBT (n = 55), nor the maintenance six months later (n = 45). (4) Conclusions: ADHD symptoms may not hinder the response to CBT or its maintenance, suggesting that TS individuals with ADHD symptoms may not require specialized CBT interventions.

Branca C, Bortolato M. The role of neuroactive steroids in tic disorders. Neurosci Biobehav Rev 2024; 160:105637. [PMID: 38519023 PMCID: PMC11121756 DOI: 10.1016/j.neubiorev.2024.105637] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2023] [Revised: 03/03/2024] [Accepted: 03/19/2024] [Indexed: 03/24/2024]
Abstract
Tics are sudden, repetitive movements or vocalizations. Tic disorders, such as Tourette syndrome (TS), are contributed by the interplay of genetic risk factors and environmental variables, leading to abnormalities in the functioning of the cortico-striatal-thalamo-cortical (CSTC) circuitry. Various neurotransmitter systems, such as gamma-aminobutyric acid (GABA) and dopamine, are implicated in the pathophysiology of these disorders. Building on the evidence that tic disorders are predominant in males and exacerbated by stress, emerging research is focusing on the involvement of neuroactive steroids, including dehydroepiandrosterone sulfate (DHEAS) and allopregnanolone, in the ontogeny of tics and other phenotypes associated with TS. Emerging evidence indicates that DHEAS levels are significantly elevated in the plasma of TS-affected boys, and the clinical onset of this disorder coincides with the period of adrenarche, the developmental stage characterized by a surge in DHEAS synthesis. On the other hand, allopregnanolone has garnered particular attention for its potential to mediate the adverse effects of acute stress on the exacerbation of tic severity and frequency. Notably, both neurosteroids act as key modulators of GABA-A receptors, suggesting a pivotal role of these targets in the pathophysiology of various clinical manifestations of tic disorders. This review explores the potential mechanisms by which these and other neuroactive steroids may influence tic disorders and discusses the emerging therapeutic strategies that target neuroactive steroids for the management of tic disorders.

Abstract
Purpose Adults with Tourette syndrome (TS) have worse mental health, physical health, and quality of life than the general population. The factors contributing to negative outcomes across multiple health domains in adults with TS remain uncertain, in part due to a lack of longitudinal studies in this population. In attempt to address these knowledge gaps, our center has initiated development of a regional registry for adults with TS. During the goal-setting and design phase of registry development, we conducted focus groups with adults with TS to identify research issues of greatest importance to this population and to obtain feedback on design and implementation of an adult TS registry. Patients and Methods Participants were recruited from a tertiary care adult TS clinic and from institutional research registries. Focus groups were conducted online and were moderated by a qualitative research expert. Qualitative data analysis was performed using an iterative inductive/deductive approach. Results Across four focus groups, adult TS participants (n=22) expressed a variety of research priorities, including developing more effective treatments for tics, identifying risk factors for tic persistence into adulthood, clarifying the interaction between TS symptoms and women's health, clarifying the relationships between TS and other mental and physical health disorders, and addressing day-to-day living issues. Focus group participants were generally enthusiastic about creation of an adult TS registry. They indicated that adults with TS are more likely to engage with a registry that logistically accommodates participants (eg, by offering a wide range of visit times, by providing telehealth options) and that fosters bidirectional interaction (eg, by disseminating results regularly, by involving participants in registry design and implementation, by notifying participants of support resources). Conclusion Focus group input clarifies the research priorities of adults with TS and will inform the ongoing development of an adult TS registry.

Abstract
Background and Objective Tourette Syndrome (TS) and Persistent Motor or Vocal Tic Disorders (PMVT) are more prevalent in males (vs. females). Females with TS may have a delay in diagnosis, and more complex tic features (vs. males). With respect to comorbidities, obsessive-compulsive disorder (OCD) is more prevalent in females; attention-deficit hyperactivity disorder (ADHD) is more prevalent in males. Less is known about sex differences in PMVT. This study analyzes sex differences in outcomes among individuals with TS and PMVT in the Tourette Association of America International Consortium for Genetics dataset (TAAICG). Design/Methods Data from 2403 individuals (N=2109 TS; N=294 PMVT) from the TAAICG were analyzed to explore the relationship between sex and TS or PMVT outcomes: age at tic onset; age at diagnosis; time-to-diagnosis; tic severity; and comorbidity rates. Regression models were adjusted for age and family relationships to examine the impact of sex on outcomes. Results Females with TS (25.5% of the sample) had a later age of symptom onset (6.5±2.8 vs. 6.0±2.7; p=0.001), later age at diagnosis (13.3±11.2 vs. 10.7±8.1; p=0.0001), and a longer time-to-diagnosis [3 (1,7) vs. 2 (1,5), p=0.01] than males. The total Yale-Global Tic Severity Scale (YGTSS) was lower in females with TS (28.4±9.1 vs. 30.7±8.7); p<0.0001); OCD was slightly more prevalent in females (55% vs. 48.7%; p=0.01) although OCD severity did not differ by sex; ADHD was more prevalent in males (55.7% vs 38.9%; p<0.001). Females with TS had 0.46 lower odds of being diagnosed with TS (p<0.00001). Females with PMVT (42.9% of the sample) had an earlier age of symptom onset (7.9±3.3 vs. 8.9±3.7; p=0.05). Motor or vocal tic severity (YGTSS) was not significantly different. OCD, but not ADHD, was more prevalent in females (OCD: 41.9% vs. 22.2%; p<0.001: ADHD:16.5% vs 21.0%; p=0.4). Conclusion Females with TS are less likely to be formally diagnosed and have a later age of symptom onset, later age at diagnosis, longer time-to-diagnosis, higher prevalence of OCD, and lower prevalence of ADHD (vs. males). Females with PMVT have an earlier age of symptom onset, higher prevalence of OCD, but similar ADHD prevalence rates (vs. males). Females with TS and PMVT may be clinically different than males with TS. Future research is needed to understand differences longitudinally in TS and PMVT.

Abstract
Objective: To review the current state of the literature regarding anxiety symptoms and anxiety disorders in chronic tic disorder (CTD). Results: We conducted a literature search on anxiety and tic disorders. Anxiety symptoms and anxiety disorders are common in youth with CTD, with ∼30%-50% of youth with CTD having at least one co-occurring anxiety disorder. Tics often improve by young adulthood but anxiety symptoms tend to persist, or worsen, over time. Anxiety and tics are closely related, but the exact nature of their relationship is poorly understood. We discuss some potential ways in which anxiety and tics are linked with an emphasis on the underlying brain circuitry involved. The relationship between anxiety and tics may be related to the premonitory urge. In addition, stress hormones may link anxiety and tics. Individuals with CTD have greater activation of their hypothalamic-pituitary-adrenal system in response to acute stress. We also review the impact of anxiety on youth with CTD and approaches to management of anxiety in youth. Conclusions: Anxiety is common in youth with CTD, is associated with more severe CTD, and can adversely affect a child's function. Thus, it is important to identify anxiety disorders in CTD and manage them appropriately.

Abstract
Tourette syndrome (TS) and obsessive-compulsive disorder (OCD) are two neuropsychiatric disorders that frequently co-occur. Previous evidence suggests a shared genetic diathesis underlying the comorbidity of TS and OCD. This review aims to comprehensively summarize the current literature on the genetic factors linked with TS and its comorbidities, with a focus on OCD. Family studies, linkage analysis, cytogenetic studies, and genome-wide association studies (GWAS) have played a pivotal role in identifying common and rare genetic variants connected with TS and OCD. Although the genetic framework of TS and OCD is complex and multifactorial, several susceptibility loci and candidate genes have been identified that might play a crucial role in the pathogenesis of both disorders. Additionally, post-infectious environmental elements have also been proposed to contribute to the development of TS-OCD, although the dynamics between genetic and environmental factors is not yet fully understood. International collaborations and studies with well-defined phenotypes will be crucial in the future to further elucidate the genetic basis of TS and OCD and to develop targeted therapeutic strategies for individuals suffering from these debilitating conditions.

Abstract
Objectives According to the 10th revision of the International Classification of Diseases, the main categories of tic disorders (F95.0, F95.1, and F95.2) follow a diagnostic hierarchy based on the duration and diversity of tic symptoms. The present study investigated the use of this diagnostic hierarchy in real-world clinical practice. Methods Based on the National Health Insurance Service-National Health Information Database, the diagnosis of transient tic disorder (F95.0) made after a diagnosis of chronic motor or vocal tic disorder (F95.1) or Tourette's syndrome (F95.2) and diagnosis of chronic motor or vocal tic disorder (F95.1) made after a diagnosis of Tourette's syndrome (F95.2) were referred to as type A errors. The diagnosis of transient tic disorder (F95.0) repeated after a period of >12 months was referred to as type B error. Demographic and clinical differences according to the diagnostic error types were analyzed using analysis of variance, Student's t-tests, and chi-squared tests. Results Most participants (96.5%) were without errors in the diagnosis of tic disorders. Higher proportions of males (p=0.005) and antipsychotic prescriptions (p<0.001) were observed in patients with type A or B diagnostic errors. A higher proportion of health insurance holders was observed among those with type A errors (p=0.027). Conclusion Errors were absent in majority of the tic diagnoses in real-world clinical practice in terms of the diagnostic hierarchy.

Abstract
BACKGROUND The frequency, clinical characteristics, and associated symptoms of comorbid tic disorders in individuals with autism spectrum disorder (ASD) remain unclear. METHODS We included subsets of individuals from a larger genetic study who were diagnosed with ASD (n = 679; age: 4-18 years) and completed the Yale Global Tic Severity Scale (YGTSS) questionnaire. Based on the YGTSS score, the individuals were divided into two groups: ASD only (n = 554) and ASD with tics (n = 125). Individuals were assessed using the verbal and non-verbal intelligence quotient (IQ), Vineland Adaptive Behavior Scale (VABS-2), Social Responsiveness Scale-2 (SRS-2), Child Behavior Checklists (CBCL), and Yale-Brown Obsessive-Compulsive Scale (YBOCS), followed by between-group comparisons. All statistical analyses were performed using the Statistical Package for the Social Sciences (SPSS) version 26. RESULTS Tic symptoms were observed in 125 (18.4%) participants; among them, most participants presented both motor and vocal tics (n = 40, 40.0%). The ASD with tics group had a significantly higher average age and full-scale IQ score than the ASD only group. After adjusting for age, the ASD with tics group had significantly higher scores in the SRS-2, CBCL, and YBOCS subdomains than the ASD only group. Furthermore, all variables except the non-verbal IQ and VABS-2 scores were positively correlated with the YGTSS total score. Finally, the proportion of tic symptoms was significantly higher among individuals with a higher IQ score (≥ 70). CONCLUSIONS The IQ score was positively correlated with the proportion of tic symptoms among individuals with ASD. Moreover, the severity of the core and comorbid symptoms of ASD was associated with the occurrence and severity of tic disorders. Our findings suggest the need for appropriate clinical interventions for individuals with ASD. Trial registration This study retrospectively registered participants.

Abstract
Due to the global increase in the number of patients with Functional Tic-Like Behaviors (FTLB), it has become increasingly important to find reliable differences between this patient group and patients with organic tics (OTs), which can be used in differential diagnosis. The purpose of this retrospective study was to critically examine both established and suggested differences between the patient groups. A total of 53 FTLB patients and 200 OT patients were included. Several findings from the current literature were replicated in this study: Compared to patients with OTs, patients with FTLB had significantly more complex tics, were older at symptom onset, were more likely to be female, and were less likely to have family members with tics. Furthermore, the study also revealed new differences between the groups: Patients with FTLB had significantly more family members with a psychiatric disorder, were more likely to have experienced an adverse psychosocial event immediately before symptom onset, and had significantly fewer simple tics. Finally, this study was unable to replicate the previously found differences in comorbidities between patients with OTs and FTLB. These findings could contribute significantly to the understanding of FTLB's etiology and to improve diagnosis, as including the presence of simple tics and comorbidities in the diagnostic criteria might be discussed in future studies.

Abstract
Women with Tourette's syndrome (TS) continue to be under-researched, despite female sex being associated with increased tic-related impairment in adulthood. Existing literature indicates that individuals with TS are more likely than the general population to report self-stigma, but little is known about the subjective identities of women with TS and how this relates to psychological wellbeing. Semi-structured interviews were conducted via Zoom with a purposive sample of 11 females. All were diagnosed with TS and aged 18-28. Data was transcribed verbatim and thematic analysis applied. Five themes were established: "I'm not normal", "I just want to be me", I'm a "people pleaser", seeing oneself as an "outsider", and "it's just part of me…it's not going anywhere". Difficulties with self-acceptance and the autonomy to be one's true self were noted and appeared to be intensified by stereotypical gender roles and attempts to conceal tics. Findings also suggested that personal growth and feelings of mastery can be achieved through embracing TS as part of one's identity, or recognising it as just one aspect of the self. Psychological support focused on accepting and living with tics rather than reducing them may benefit this population and is currently difficult to access. Consideration should also be given to improving the availability of support groups where women with TS can meet others like themselves.

Abstract
Background The first systematic description of tics in a large sample was in 1978. Objectives To assess the phenomenology of tics in youth and investigate how age and sex influence tic phenomenology. Methods Children and adolescents with primary tic disorders have been prospectively included in our Registry in Calgary, Canada, since 2017. We examined tic frequency and distribution using the Yale Global Tic Severity Scale, differences between sexes, and changes in tic severity with age and with mental health comorbidities. Results A total of 203 children and adolescents with primary tic disorders were included (76.4% males; mean age = 10.7 years, 95% CI = 10.3-11.1). At first assessment, the most common simple motor tics were eye blinking (57%), head jerks/movements (51%), eye movements (48%) and mouth movements (46%); 86% had at least one simple facial tic. The most frequent complex motor tics were tic-related compulsive behaviors (19%). Throat clearing was the most common simple phonic tic (42%); 5% only had coprolalia. Females had higher frequency and intensity of motor tics than males (P = 0.032 and P = 0.006, respectively), associated with greater tic-related impairment (P = 0.045). Age was positively correlated with the Total Tic Severity Score (coefficient 0.54, P = 0.005), along with the number, frequency and intensity of motor tics but not with their complexity. Psychiatric comorbidities were associated with greater tic severity. Conclusions Our study suggests that age and sex affect clinical presentation in youth with tics. The phenomenology of tics in our sample was similar to the 1978 description of tics, and contrasts with functional tic-like behaviors.

Abstract
OBJECTIVE Among adults with Tourette syndrome, depression and anxiety symptoms are widely prevalent and consistently associated with poor quality of life. Important knowledge gaps remain regarding mood and anxiety dimensions of the adult Tourette syndrome phenotype. Taking a dimensional approach, this study sought to determine the prevalence, severity, and clinical correlates of depression and anxiety symptoms in a clinical sample of adults with Tourette syndrome and other chronic tic disorders. METHODS A retrospective chart review was conducted of all adults with a chronic tic disorder presenting to a tertiary care Tourette syndrome clinic between December 2020 and July 2022. Information extracted during chart review included data from scales administered as part of routine care: Quality of Life in Neurological Disorders (Neuro-QoL) Depression Short Form, Neuro-QoL Anxiety Short Form, Adult Attention-Deficit/Hyperactivity Disorder Self-Report Screening Scale, Dimensional Obsessive-Compulsive Scale, and Yale Global Tic Severity Scale. Relationships between variables were examined by conducting between-group, correlation, and multivariable regression analyses. RESULTS Data from 120 adult patients with a chronic tic disorder (77 men and 43 women) were analyzed. Neuro-QoL Anxiety scores were elevated in 66% of the cohort; Neuro-QoL Depression scores were elevated in 26%. Neuro-QoL Anxiety scores were significantly higher than general population norms, whereas Neuro-QoL Depression scores were not. After adjustment for covariates, depressive and anxiety symptom severity scores were significantly associated with each other and with obsessive-compulsive disorder symptom severity but not with tic severity. Sex-based differences emerged in the analyses. CONCLUSIONS Among adults with chronic tic disorder, anxiety symptoms were more prevalent and severe than depressive symptoms, co-occurring psychiatric symptoms were more tightly linked with each other than with tic severity, and sex-based differences were evident.

Abstract
Health-related conditions often differ qualitatively or quantitatively between individuals of different birth-assigned sexes and gender identities, and/or with different gendered experiences, requiring tailored care. Studying the moderating and mediating effects of sex-related and gender-related factors on impairment, disability, wellbeing and health is of paramount importance especially for neurodivergent individuals, who are diagnosed with neurodevelopmental conditions with uneven sex/gender distributions. Researchers have become aware of the myriad influences that sex-related and gender-related variables have on the manifestations of neurodevelopmental conditions, and contemporary work has begun to investigate the mechanisms through which these effects are mediated. Here we describe topical concepts of sex and gender science, summarize current knowledge, and discuss research and clinical challenges related to autism, attention-deficit/hyperactivity disorder and other neurodevelopmental conditions. We consider sex and gender in the context of epidemiology, behavioural phenotypes, neurobiology, genetics, endocrinology and neighbouring disciplines. The available evidence supports the view that sex and gender are important contributors to the biological and behavioural variability in neurodevelopmental conditions. Methodological caveats such as frequent conflation of sex and gender constructs, inappropriate measurement of these constructs and under-representation of specific demographic groups (for example, female and gender minority individuals and people with intellectual disabilities) limit the translational potential of research so far. Future research and clinical implementation should integrate sex and gender into next-generation diagnostics, mechanistic investigations and support practices.

Abstract
Tics are repetitive, patterned, and nonrhythmic movements or vocalizations/audible sounds that are misplaced in context. Phenomenology and characteristics of tics (e.g., premonitory urge, suppressibility) differentiate them from compulsions, stereotypies, functional tic-like behaviors, and other types of hyperkinetic movement disorders. With a prevalence of approximately 1% in school-aged boys, Tourette syndrome (TS) is considered a common childhood-onset neurodevelopmental disorder, defined by the combination of at least two motor tics and at least one phonic tic lasting more than 1 year. TS is a highly heritable disorder, with a wide spectrum of severity. In some individuals, tics can cause pain, distress, functional impairment, or stigmatization. About 90% of individuals with TS have at least one mental health comorbidity (attention-deficit/hyperactivity disorder, obsessive-compulsive disorder, anxiety/depressive disorders). These comorbidities significantly impact patients' quality of life and must therefore be screened and managed accordingly in this population. Treatment of tics is based on behavioral therapies targeting tics (habit reversal training included in the comprehensive behavioral intervention for tics, and exposure and response prevention for tics), in association with medication if needed (e.g., alpha-2-agonists, second-generation antipsychotics). Deep brain stimulation is considered an experimental option in the most severe, treatment-resistant patients. In adulthood, less than 25% of individuals still have moderate or severe tics.

Abstract
Zusammenfassung. Theoretischer Hintergrund: Die Funktion des Vorgefühls in der Pathogenese und Aufrechterhaltung von Tic-Störungen (TS) wird in den letzten Jahren verstärkt erforscht. Die mögliche funktionelle Bedeutung der Vorgefühle wird aber noch nicht ausreichend verstanden. Methode: Im vorliegenden Review wird der Kenntnisstand zu Vorgefühlen entlang eines integrativen funktionalen Störungsmodells zusammengefasst. Ergebnisse: Im Vergleich zum Jugendalter nehmen Tic-Symptome bei Tic-Störungen im Erwachsenenalter ab, während immer mehr Betroffene ein Vorgefühl berichten. Hierbei kann zwischen einem allgemeinen Vorgefühl (trait) und dem Drang, Tics auszuführen (state) unterschieden werden. Das Vorgefühl als trait ist abhängig von der Interozeptionsfähigkeit. An den Drang, Tics auszuführen, kann habituiert werden, moderiert von Aufmerksamkeits- und Attributionsprozessen. Durch das Auflösen des Vorgefühl-Tic-Reizreaktionsmusters reduzieren sich die Tic-Symptome. Schlussfolgerung: Für weitere Erkenntnisse in Bezug auf die Bedeutung von Vorgefühl und den Drang, Tics auszuführen, sollten zukünftige Forschungsansätze Drang und allgemeine Vorgefühle in therapeutischen Interventionsstudien berücksichtigen, weitere Interozeptionsparadigmen einbeziehen und die Entwicklung von allgemeinem Vorgefühl und Drang über die Lebensspanne hinweg untersuchen.

Abstract
Tic disorders have a strong male predominance, with a male-to-female ratio of 4:1 in Tourette syndrome (TS) and 2:1 in persistent tic disorders. In other neurodevelopmental conditions, such as autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD), the disparity in sex distribution has been partially related to differences in symptom presentation between males and females. In tic disorders, however, little research has been conducted on this topic, probably due to the limited access to large samples with a significant proportion of females. The aim of this study was to describe sex differences in the clinical presentation of tic disorders in children and adolescents in one of the largest pediatric samples with TS/persistent tic disorders (n = 709, 23.3% females) recruited as part of the European Multicenter Tics in Children Study (EMTICS). Validated measures assessed the severity of tics and comorbid psychiatric symptoms. Using mixed-effect models, we found that sex had a significant influence on the severity of tics, ADHD symptoms, ASD symptoms, and emotional problems. Males had more severe symptoms than females, except for emotional problems. We also observed a statistically significant interaction between sex and age on the severity of tics and compulsions, with females showing higher symptom severity with increasing age than males. These findings indicate that the clinical presentation of TS/persistent tic disorders varies with sex. Males seem to exhibit a more noticeable pattern of clinical symptoms at a younger age that may contribute to their earlier detection in comparison to females.

Abstract
Practice guidelines endorse comprehensive behavioral intervention for tics (CBIT) as first-line treatment for tic disorders (TD) in youth. Nevertheless, CBIT is rarely available due to various barriers. This study evaluated the feasibility and potential effectiveness of an Internet-based, self-help CBIT program (ICBIT) guided by parents with minimal therapist support delivered via telepsychotherapy. Forty-one youths, aged 7-18 years, were randomly assigned to receive either ICBIT (n = 25) or a wait-list (WL) condition (n = 16) in a crossover design. ICBIT was feasible to implement and at post-treatment, 64% of the participants have improved significantly. Results demonstrated clinically meaningful reductions in tic severity and improved youth global impairment and functioning. Gains were maintained over a 6-month follow-up period. The effect size for the primary outcome measure (Yale Global Tic Severity Scale) ranged between large effect size (Cohen"s d = 0.91) at post-intervention to very large effect size (Cohen's d = 2.25) 6 months after the end of the acute intervention. These were comparable to face-to-face delivery treatment trials for TD. Participants rated the intervention as highly acceptable and satisfactory. Youth receiving ICBIT experienced improvement in self-esteem and comorbidity. Finally, during the COVID-19 pandemic, the ICBIT program enabled the delivery of the intervention consecutively without interruption. The results observed provide preliminary evidence of the feasibility and effectiveness of this innovative modality to assist youth with TD and remove various barriers to treatment, including those during a public crisis, such as the COVID-19 pandemic. Larger studies with an active control group are warranted.Trial registration URL: http://clinicaltrials.gov, ClinicalTrials.gov Identifier: NCT04087616.

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
Tourette Disorder (TD) is a male predominant neurodevelopmental disorder characterized by tics and frequent psychiatric comorbidities. Girls with TD have later peak symptoms, less remission with age, and worse impairment from tics, particularly in adulthood. Female TD patients are less likely to have Attention Deficit Hyperactivity Disorder and more likely to have anxiety and mood disorders. Hyperandrogenism is associated with TD in both sexes, and neuroanatomic sexual dimorphism is reduced in adult TD patients. Some women report catamenial tics, which may relate to estrogen withdrawal or rises in allopregnanolone. Limited data suggest that several neuroanatomic alterations present in boys with TD are not present in girls with TD. Female sex predicts better response to haloperidol. Further research into female tic pathophysiology may influence sex-specific treatment development.

Abstract
A number of studies reported the possible differences between men and women in movement disorders. Evidence shows that estrogens may have a neuroprotective effect and may modulate the neurodevelopment of the different brain structures. Movement disorders including Parkinson's disease, dementia with Lewy body, Huntington's disease, Tourette's syndrome, and dystonia among others display significant clinical differences between sexes, with structural differences in the dopaminergic pathways between men and women. Here we summarize the most relevant clinical aspects of some of the most common movement disorders, highlighting the differences in disease onset, clinical presentation, therapy, and outcomes. Increased recognition of these differences may help physicians better understand the pathophysiology of these conditions and provide a tailored therapeutic approach.

Abstract
AbstractAlthough boys are disproportionately affected by tics in Tourette syndrome (TS), this gender bias is attenuated in adulthood and a recent study has suggested that women may experience greater functional interference from tics than men. The authors assessed the gender distribution of adults in a tertiary University-based TS clinic population and the relative influence of gender and other variables on adult tic severity (YGTSS score) and psychosocial functioning (GAF score). We also determined retrospectively the influence of gender on change in global tic severity and overall TS impairment (YGTSS) since adolescence. Females were over-represented in relation to previously published epidemiologic surveys of both TS children and adults. Female gender was associated with a greater likelihood of tic worsening as opposed to tic improvement in adulthood; a greater likelihood of expansion as opposed to contraction of motor tic distribution; and with increased current motor tic severity and tic-related impairment. However, gender explained only a small percentage of the variance of the YGTSS global severity score and none of the variance of the GAF scale score. Psychosocial functioning was influenced most strongly by tic severity but also by a variety of comorbid neuropsychiatric disorders.

Abstract
In a range of neurological conditions, including movement disorders, sex-related differences are emerging not only in brain anatomy and function, but also in pathogenesis, clinical features and response to treatment. In Parkinson disease (PD), for example, oestrogens can influence the severity of motor symptoms, whereas elevation of androgens can exacerbate tic disorders. Nevertheless, the real impact of sex differences in movement disorders remains under-recognized. In this article, we provide an up-to-date review of sex-related differences in PD and the most common hyperkinetic movement disorders, namely, essential tremor, dystonia, Huntington disease and other chorea syndromes, and Tourette syndrome and other chronic tic disorders. We highlight the most relevant clinical aspects of movement disorders that differ between men and women. Increased recognition of these differences and their impact on patient care could aid the development of tailored approaches to the management of movement disorders and enable the optimization of preclinical research and clinical studies.

Abstract
Movement disorders in women during pregnancy are uncommon. Therefore, high quality studies are limited, and guidelines are lacking for the treatment of movement disorders in pregnancy, thus posing a significant therapeutic challenge for the treating physicians. In this chapter, we discuss movement disorders that arise during pregnancy and the preexisting movement disorders during pregnancy. Common conditions encountered in pregnancy include but are not limited to restless legs syndrome, chorea gravidarum, Parkinson disease, essential tremor, and Huntington disease as well as more rare movement disorders (Wilson's disease, dystonia, etc.). This chapter summarizes the published literature on movement disorders and pharmacologic and surgical considerations for neurologists and physicians in other specialties caring for patients who are pregnant or considering pregnancy.

Abstract
AIM To determine the comorbidity of epilepsy and chronic tic disorders (HTR) in children and adolescents based on the results of video-EEG monitoring and treatment efficacy. MATERIAL AND METHODS One hundred and sixteen patients diagnosed with HTR, 83 boys and 33 girls, aged from 3 to 15 years, were studied. Clinical psychoneurological examination, psychological testing and video-EEG monitoring were performed at the first stage of the study. An effect of treatment was assessed at the second stage. RESULTS AND CONCLUSION The high prevalence of epileptiform activity was observed in 46.6% of patients with HTR, comorbidity of epilepsy and chronic tic disorders in 16.4%. Antiepileptic drugs, in particular extended release valproate (depakine chronosphere), are most effective for both epilepsy and tic disorders.

Abstract
OBJECTIVE The present study compared sleep sufficiency in youth with current Tourette's disorder (TD), history of TD and matched case controls, and examined predictors of sufficient sleep using a large US population-based survey. METHOD Participants were 673 caregivers of youth aged 6 to 17 years (298 with current TD, 122 with a history of TD with no endorsement of current diagnosis, and 254 matched case controls) from the 2007 and 2011-2012 versions of the National Survey of Children's Health. History and current TD status, current comorbidity (attention deficit/hyperactivity disorder, anxiety, and depression) and psychiatric medication status were assessed by yes/no items. Current TD severity was dichotomized into mild or moderate/severe symptoms. Sleep was assessed by parent-reported number of sufficient nights their child slept in the past week. RESULTS Univariate analysis of variance yielded significant group differences in nights of sufficient sleep (F[2,369.70] = 71.53, p < .001), with controls having 1.5 more nights per week relative to both TD groups (p < .001). With respect to predictors of sufficient sleep, the analysis of covariance yielded a significant age × sex × TD severity interaction (F[1,15.84] = 4.28, p = .04) such that older adolescent males with mild TD had significantly fewer nights of sufficient sleep than children (p = .004) and early adolescents (p = .002; F[2,54.93] = 7.45, p = .001). Early adolescent females with moderate/severe TD had fewer nights of sufficient sleep relative to males (p = .008). Comorbidity type and psychiatric medication status did not significantly predict sleep. CONCLUSION Findings suggest that insufficient sleep in youth with TD persists independently of comorbidity or psychiatric medication status. Findings highlight the importance of clinical sleep monitoring in this population.

Abstract
OBJECTIVE Gilles de la Tourette syndrome (GTS) and depression are both common disorders. It has been suggested that depression occurs in 13%-76% GTS patients. Despite this, there are few studies into the specific relationships and correlates between the two disorders. There is only some consensus as to the precise relationship between the two disorders. MATERIALS AND METHODS We undertook the study to investigate the relationship between depressive symptomatology and the core clinical features of GTS in a well-characterized clinical population of youth with this disorder. Our aim was to verify the association between depression and comorbid obsessive-compulsive disorder and explore further other potential associations highlighted in some, but not all, of the studies focused on this topic. RESULTS Our results demonstrated that (1) the GTS patients were significantly older than the controls, (2) the GTS patients were significantly more depressed than controls, (3) depression was associated with tic severity, (4) the Diagnostic Confidence Index scores were higher in GTS patients without depression, (5) anxiety, attention-deficit/hyperactivity disorder (ADHD), conduct disorder (CD), and behavioral problems were significantly associated with depression, and (6) finally, patients with GTS and depression have a positive family history of depression. However, obsessionality (CY-BOCS) did not differentiate between depressed and not depressed GTS patients. CONCLUSIONS Depression is common in patients with GTS and occurs significantly more in GTS than in controls. Depression is significantly associated with GTS factors such as tic severity, comorbidity with ADHD, and the presence of coexistent anxiety, CDs, and behavior problems. Depression is importantly significantly associated with a positive family history of depression. Intriguingly, depression in our sample was not related to obsessionality.

Abstract
Background: Gilles de la Tourette syndrome (TS) is a complex neuropsychiatric disorder defined by the presence of motor and phonic tics, but often associated with psychiatric comorbidities. The main objective of this study was to explore the clinical presentation and comorbidities of TS. Method: We analyzed clinical data obtained from a large sample (n = 1032; 529 children and 503 adults) of patients with tic disorders from one single German TS center assessed by one investigator. Data was collected with the help of an expert-reviewed semi-structured interview, designed to assess tic severity and certain comorbidities. Group comparisons were carried out via independent sample t-tests and chi-square tests. Results: The main findings of the study are: (1) tic severity is associated with the presence of premonitory urges (PU), copro-, echo-, and paliphenomena and the number of comorbidities, but not age at tic onset; it is higher in patients with comorbid obsessive-compulsive disorder (OCD) than in patients with comorbid attention deficit/hyperactivity disorder (ADHD). (2) PU were found to be highly associated with “not just right experiences” and to emerge much earlier than previously thought alongside with the ability to suppress tics (PU in >60% and suppressibility in >75% at age 8–10 years). (3) Self-injurious behavior (SIB) is highly associated with complex motor tics and coprophenomena, but not with OCD/obsessive-compulsive behavior (OCB). While comorbid ADHD is associated with a lower ability to suppress tics, comorbid depression is associated with sleeping problems. Discussion: Our results demonstrate that tic severity is not influenced by age at onset. From our data, it is suggested that PU represent a specific type of “not just right experience” that is not a prerequisite for tic suppression. Comorbid ADHD reduces patients' ability of successful tic suppression. Our data suggest that SIB belongs to the coprophenomena spectrum and hence should be conceptualized as a complex tic rather than a compulsion. Finally, this study strongly supports the hypothesis that TS+OCD is a more severe form of TS and that comorbid OCD/OCB, depression, and anxiety belong to the TS spectrum, while ADHD should be better conceptualized as a separate problem.

Abstract
OBJECTIVE The objective of this study was to examine: (1) the prevalence of diagnosed Tourette syndrome in Canada by sex in youth (aged 12-17) and adults and (2) socioeconomic factors in this population. BACKGROUND The majority of epidemiological studies of tics have focused on children and youth, with few studies describing the prevalence of tics in adult populations. METHODS Canadian data on Tourette syndrome prevalence were derived from the Canadian Community Health Survey 2010 and 2011 cycles, a Statistics Canada population-based cross-sectional survey that collects information related to health status. We determined the prevalence of diagnosed Tourette syndrome and examined sociodemographic factors, including age, sex, education, income, employment, and birthplace. RESULTS Overall, 122,884 Canadians participated in the surveys, with 122 participants diagnosed with Tourette syndrome. The prevalence of Tourette syndrome was higher in males in youth: 6.03 per 1000 (95% confidence interval: 3.24-8.81) in males versus 0.48 per 1,000 (95% confidence interval: 0.05-0.91) in females, with a prevalence risk ratio of 5.31 (95% confidence interval: 2.38-11.81). In adults, the prevalence of Tourette syndrome was 0.89 per 1,000 (95% confidence interval: 0.48-1.29) in males versus 0.44 (95% confidence interval: 0.16.0-0.71) in females, with a prevalence risk ratio of 1.93 (95% confidence interval: 1.21-3.08). After adjusting for age and sex, adults with Tourette syndrome had lower odds of receiving postsecondary education or being employed and higher odds of having income lower than the median and receiving governmental support. CONCLUSION Data on the prevalence of Tourette syndrome in adults are scarce because most studies focus on children. Our data demonstrate a decreasing prevalence risk ratio for sex in adults compared to children. A diagnosis of Tourette syndrome is associated with lower education, income, and employment in adulthood. © 2016 International Parkinson and Movement Disorder Society.

Abstract
Quality of life of children with Tourette Syndrome (TS) is impacted greatly by its symptoms and their social consequences. Habit Reversal Training (HRT) is effective but has not, until now, been empirically evaluated in groups. This randomised controlled trial evaluated feasibility and preliminary efficacy of eight HRT group sessions compared to eight Education group sessions. Thirty-three children aged 9-13 years with TS or Chronic Tic Disorder took part. Outcomes evaluated were tic severity and quality of life (QoL). Tic severity improvements were found in both groups. Motor tic severity (Yale Global Tic Severity Scale) showed greatest improvements in the HRT group. Both groups showed a strong tendency toward improvements in patient reported QoL. In conclusion, group-based treatments for TS are feasible and exposure to other children with tics did not increase tic expression. HRT led to greater reductions in tic severity than Education. Implications, such as cost-effectiveness of treatment delivery, are discussed.

Abstract
Background Tourette syndrome (TS) is a neurodevelopmental disorder characterized by tics and neuropsychiatric co-morbidities like Obsessive Compulsive Disorder (OCD) and Attention Deficit Disorder (ADHD), among others. In many instances tics get better with age but this is not always true regarding the psychiatric co-morbidities. Methods This manuscript reviews the disease-specific Quality of Life (QOL) instruments used to measure disability in TS and the existing literature on sources of functional impairment in children and adults with TS. Results Traditionally, disability in TS has been recorded using objective measures. In recent years there has been a development of disease-specific instruments to measure subjectively the impact of the different aspects of TS on the patient's daily function. The differential impact of tics vs. the psychiatric co-morbidities in children with TS is an issue of debate in the existing literature. In adults with TS, the literature is scant, therefore the sources of disability in this group are even less defined compared to children. Discussion As clinicians, we need to focus on determining the sources of disability in children and adults with TS so we can target our interventions successfully.

Abstract
There is a growing body of qualitative literature describing the lived experiences of people with tic disorders (TDs). The aim of this paper was to conduct a systematic review of this literature, synthesizing the perspectives of individuals on their experiences. Meta-synthesis methodology was utilized to review and draw together findings from 10 articles, from which key concepts were extracted, and over-arching themes generated. Six themes were identified to encompass the experience of TDs, including (1) cultural, semantic issues of the condition; (2) negative experiences in organizations and treatment; (3) the value and negative impact on interpersonal relationships; (4) personal identity in the constant presence of TDs; (5) concerns for the future; and (6) strategies to control and manage the observable presence of tics. Adaptive coping strategies were found to encompass continuous social adaptation, strategies to manage tics and social perceptions, self-acceptance, advocacy, and support from others. The results highlighted the significant role of social and cultural issues related to understanding and stigma, which underpinned many of the lived experiences. Implications for clinical practice in supporting individuals with TDs were also highlighted.

Abstract
Data on medical treatment of children and adolescents with tic disorders are scarce. This study examined the administrative prevalence of psychopharmacological prescriptions in this patient group in Germany. Data of the largest German health insurance fund were analysed. In outpatients aged 0-19 years with diagnosed tic disorder, psychotropic prescriptions were evaluated for the years 2006 and 2011. In 2011, the percentage of psychotropic prescriptions was slightly higher than in 2006 (21.2 vs. 18.6%). The highest prescription prevalence was found in Tourette syndrome (51.5 and 53.0%, respectively). ADHD drugs were most frequently prescribed, followed by antipsychotics. In 2011, prescriptions of second generation antipsychotics (SGA) were higher and prescriptions of first generation antipsychotics (FGA) lower than in 2006. Concerning prescribed antipsychotic substances, in 2011 risperidone prescriptions were higher and tiapride prescriptions lower. Paediatricians issued 37.4%, and child and adolescent psychiatrists issued 37.1% of psychotropic prescriptions. The FGA/SGA ratio was highest in GPs (1.25) and lowest in child and adolescent psychiatrists (0.96). From 2006 to 2011, there was only a slight increase in psychotropic prescriptions for children and adolescents with a diagnosis of tic disorder in Germany, which stands in contrast towards the significant increase in psychotropic prescriptions in other child and adolescent psychiatric disorders (e.g. ADHD). There were marked differences in treatment patterns by tic disorder subgroups, with Tourette syndrome patients receiving most frequently psychopharmacotherapy. Risperidone prescriptions increased, probably reflecting a switch in prescribing practice towards up-to-date treatment guidelines. In primary care physicians, dissemination of current tic disorder treatment guidelines might constitute an important educational goal.

Abstract
This Series is a personal narrative of my experience with patients with Gilles de la Tourette syndrome and covers its definition and history since the first description in 1825. Controversy entered the prevalence debate early. Although originally considered very rare, in the 1980s, Tourette's syndrome was reported to be common. However, Tourette's syndrome has been shown to occur at a prevalence of about 0·85% to 1%. Tourette's syndrome is more common in the male population, more prominent during childhood, and usually improves, but does not disappear with age. Tourette's syndrome is considered less common in people of sub-Saharan black African, African-American, and American Hispanic ethnic origin. The phenomenology is similar worldwide, indicating a biological basis. The hallmark characteristics are multiple motor and one or more vocal/phonic tics. Other associated features include premonitory urges, a waxing and waning course, and to a much lesser degree, coprolalia. Comorbid disorders are common and are suggested to include obsessive-compulsive disorder and behaviours, attention deficit hyperactivity disorder, and autistic spectrum disorder. Coexistent psychopathologies are suggested to include depression and conduct and personality disorders. Importantly, I argue that Tourette's syndrome is not a unitary condition. Finally, I offer suggestions for future research.

Abstract
See Jackson (doi:10.1093/brain/awu338) for a scientific commentary on this article. The neural substrate of Gilles de la Tourette syndrome is unknown. Worbe et al. use probabilistic tractography to demonstrate widespread structural abnormalities in cortico-striato-pallido-thalamic white matter pathways—likely arising from abnormal brain development—in patients with this syndrome. Gilles de la Tourette syndrome is a childhood-onset syndrome characterized by the presence and persistence of motor and vocal tics. A dysfunction of cortico-striato-pallido-thalamo-cortical networks in this syndrome has been supported by convergent data from neuro-pathological, electrophysiological as well as structural and functional neuroimaging studies. Here, we addressed the question of structural integration of cortico-striato-pallido-thalamo-cortical networks in Gilles de la Tourette syndrome. We specifically tested the hypothesis that deviant brain development in Gilles de la Tourette syndrome could affect structural connectivity within the input and output basal ganglia structures and thalamus. To this aim, we acquired data on 49 adult patients and 28 gender and age-matched control subjects on a 3 T magnetic resonance imaging scanner. We used and further implemented streamline probabilistic tractography algorithms that allowed us to quantify the structural integration of cortico-striato-pallido-thalamo-cortical networks. To further investigate the microstructure of white matter in patients with Gilles de la Tourette syndrome, we also evaluated fractional anisotropy and radial diffusivity in these pathways, which are both sensitive to axonal package and to myelin ensheathment. In patients with Gilles de la Tourette syndrome compared to control subjects, we found white matter abnormalities in neuronal pathways connecting the cerebral cortex, the basal ganglia and the thalamus. Specifically, striatum and thalamus had abnormally enhanced structural connectivity with primary motor and sensory cortices, as well as paracentral lobule, supplementary motor area and parietal cortices. This enhanced connectivity of motor cortex positively correlated with severity of tics measured by the Yale Global Tics Severity Scale and was not influenced by current medication status, age or gender of patients. Independently of the severity of tics, lateral and medial orbito-frontal cortex, inferior frontal, temporo-parietal junction, medial temporal and frontal pole also had enhanced structural connectivity with the striatum and thalamus in patients with Gilles de la Tourette syndrome. In addition, the cortico-striatal pathways were characterized by elevated fractional anisotropy and diminished radial diffusivity, suggesting microstructural axonal abnormalities of white matter in Gilles de la Tourette syndrome. These changes were more prominent in females with Gilles de la Tourette syndrome compared to males and were not related to the current medication status. Taken together, our data showed widespread structural abnormalities in cortico-striato-pallido-thalamic white matter pathways in patients with Gilles de la Tourette, which likely result from abnormal brain development in this syndrome.

Abstract
BACKGROUND AND PURPOSE Recent evidence suggests that there may be more than one Gilles de la Tourette syndrome (GTS)/tic disorder phenotype. However, little is known about the common patterns of these GTS/tic disorder-related comorbidities. In addition, sex-specific phenomenological data of GTS/tic disorder-affected adults are rare. Therefore, this community-based study used latent class analyses (LCA) to investigate sex-related and non-sex-related subtypes of GTS/tic disorders and their most common comorbidities. METHODS The data were drawn from the PsyCoLaus study (n = 3691), a population-based survey conducted in Lausanne, Switzerland. LCA were performed on the data of 80 subjects manifesting motor/vocal tics during their childhood/adolescence. Comorbid attention-deficit hyperactivity disorder (ADHD), obsessive-compulsive disorder, depressive, phobia and panic symptoms/syndromes comprised the selected indicators. The resultant classes were characterized by psychosocial correlates. RESULTS In LCA, four latent classes provided the best fit to the data. We identified two male-related classes. The first class exhibited both ADHD and depression. The second class comprised males with only depression. Class three was a female-related class depicting obsessive thoughts/compulsive acts, phobias and panic attacks. This class manifested high psychosocial impairment. Class four had a balanced sex proportion and comorbid symptoms/syndromes such as phobias and panic attacks. The complementary occurrence of comorbid obsessive thoughts/compulsive acts and ADHD impulsivity was remarkable. CONCLUSIONS To the best of our knowledge, this is the first study applying LCA to community data of GTS symptoms/tic disorder-affected persons. Our findings support the utility of differentiating GTS/tic disorder subphenotypes on the basis of comorbid syndromes.

Abstract
Tourette syndrome is a hereditary, childhood-onset neurodevelopmental disorder that was first clearly described in France in 1885. This disorder is characterized by sudden, rapid, recurrent, nonrhythmic movements (motor tics) or sounds (vocal or phonic tics), often preceded by premonitory sensations or urges. Some individuals also have psychiatric comorbidities, notably attention-deficit hyperactivity disorder or obsessive-compulsive disorder. Tourette syndrome occurs worldwide, in all races and ethnicities, in both sexes and in children as well as in adults. Estimates of its prevalence in children vary, with rates of up to 1% being reported, but rates of 0.3-0.8% are thought to accurately reflect the occurrence of the disorder. Research has led to progress in many aspects of Tourette syndrome, although many questions and unmet needs remain. For example, except for rare cases, the genetic basis remains elusive. The anatomical and neuronal changes in the brain that underlie Tourette syndrome are also unclear, although the evidence increasingly implicates alterations in basal ganglia function. Treatment is often unnecessary for individuals with mild tics, but for those with moderate to severe forms of the syndrome, some drugs are available, albeit frequently ineffective. Behavioral and surgical therapies, in particular deep brain stimulation, are currently undergoing development and show promising results. This Review examines the history of Tourette syndrome and describes its clinical presentation. The article also provides an overview of the epidemiology and pathophysiology of this disorder. Current treatment strategies and potential future therapies are also discussed.
