Abstract
PURPOSE OF REVIEW Tourette syndrome (TS) and chronic tic disorders, collectively referred to as TS, are relatively common childhood onset neuropsychiatric conditions associated with functional impairment and distress. Over the past several years, clinical research has contributed to the advancement of the field's understanding of mechanisms and clinical correlates of TS. This progress has led to the development of key assessment tools and the implementation of novel interventions for individuals with TS. RECENT FINDINGS This article provides a review of innovative TS research focusing on four key themes: investigation of clinical phenomenology of TS; validation of assessment tools for TS; dissemination of current evidence-based treatments for TS; and exploration of new intervention programs. SUMMARY Cumulatively, this growing body of work presents considerable progress and provides a path forward to improve the assessment and treatment of TS.

Comorbidities and Disease Duration in Tourette Syndrome: Impact on Cognition and Quality of Life of Children. CHILDREN (BASEL, SWITZERLAND) 2024; 11:226. [PMID: 38397337 PMCID: PMC10887127 DOI: 10.3390/children11020226] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/12/2024] [Revised: 02/01/2024] [Accepted: 02/04/2024] [Indexed: 02/25/2024]
Abstract
BACKGROUND Cognitive functions represent foundational factors for mental health and quality of life (QoL). In Tourette syndrome (TS), psychiatric comorbidities are common and have been inconsistently reported to affect the cognition and QoL of patients, while the role of tic disorder duration has not been yet explored. METHODS To examine how comorbidities and TS duration may influence cognition and QoL, N = 80 children with TS (6-16 years) were evaluated using the Wechsler Intelligence Scale for Children (WISC-IV). Standardized questionnaires were used to assess the presence and severity of TS main comorbidities and QoL. Data were interpreted using linear correlations, regression, and mediation analysis. RESULTS Depression and attention-deficit/hyperactivity disorder (ADHD) symptoms accounted for poorer cognitive performance. Anxiety oppositely predicted better cognitive performance, while no significant role for obsessive compulsive disorder (OCD) was observed. Disease duration was associated with lower total IQ, verbal reasoning, and working memory abilities. Depression, anxiety, and TS duration also deeply influenced QoL measures. CONCLUSIONS TS common comorbidities have a differential impact on the cognitive abilities of children and adolescents, which translates into a complex influence on their perceived QoL. A longer clinical history of tics was related to worse cognitive outcomes, which prompts further consideration of disease duration in both clinical and research settings involving children and adolescents.

Abstract
BACKGROUND The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can invade both the peripheral and central nervous systems and impact the function of the brain. Therefore, it is necessary to evaluate the mutual influences between COVID-19 outcomes and childhood mental disorders. METHODS We examined genetic correlations and potential causalities between three childhood mental disorders and three COVID-19 phenotypes by genetically proxied analyses. The three mental disorders included attention-deficit/hyperactivity disorder (ADHD, N = 292,548), Tourette's syndrome (TS, N = 14,307), and autism spectrum disorder (ASD, N = 46,350). The three COVID-19 traits included SARS-CoV-2 infection (N = 2,597,856), hospitalized COVID-19 (N = 2,095,324), and critical COVID-19 (N = 1,086,211). Literature-based analysis was used to build gene-based pathways connecting ADHD and COVID-19. RESULTS ADHD was positively correlated with the three COVID-19 outcomes (Rg: 0.22 ~ 0.30). Our Mendelian randomization (MR) analyses found that ADHD confers a causal effect on hospitalized COVID-19 (odds ratio (OR): 1.36, 95% confidence interval (CI): 1.10-1.69). TS confers a causal effect on critical COVID-19 (OR: 1.14, 95% CI: 1.04-1.25). Genetic liability to the COVID-19 outcomes may not increase the risk for the childhood mental disorders. Pathway analysis identified several immunity-related genes that may link ADHD to COVID-19, including CRP, OXT, IL6, PON1, AR, TNFSF12, and IL10. CONCLUSIONS Our study suggests that both ADHD and TS may augment the severity of COVID-19 through immunity-related pathways. However, our results did not support a causal role of COVID-19 in the risk for the childhood mental disorders.

Abstract
Tourette Syndrome (TS) is a disorder in which the patient has a history of multiple motor and vocal tics. Depression and anxiety are common in these patients. The results of the studies show different prevalence of these disorders in patients with TS. So, the objective of the present study was to liken the prevalence of depression and anxiety in patients with TS by systematic review and meta-analysis. The present study was conducted according to PRISMA guidelines during 1997-2022. The articles were obtained from Scopus, Embase, PubMed, Web of Science (WoS) and Google Scholar databases. I2 was used to investigate heterogeneity between studies. Data were analyzed by comprehensive meta-analysis software (Version 2). Finally, 12 articles with a sample size of n = 3812 were included in the study. As a result of combining the results of the studies, the total estimate of the prevalence of depression and anxiety in patients with TS was 36.4% (95% confidence interval: 21.1-54.9%) and 53.5% (95% confidence interval: 39.9-66.6%), respectively. The results of meta-regression showed that by increasing mean age (9-31.5 years), the prevalence of depression and anxiety in patients with TS increased significantly (P<0.001). The results of the present study showed that the prevalence of depression and anxiety was high in patients with TS. Therefore, it is suggested that health officials and policy makers design measures to prevent and control these disorders.

Abstract
Tourette syndrome is a complex neuropsychiatric condition that manifests in childhood and is often associated with other psychiatric comorbidities. This case report describes a young male with Tourette syndrome with major depressive disorder and attention deficit hyperactivity disorder (ADHD) who experienced troublesome side effects due to his existing medications (escitalopram, risperidone, and methylphenidate). In order to control his tics, ameliorate depressive symptoms, and eliminate side effects of stiffness and sedation, risperidone was switched to cariprazine, a third-generation antipsychotic medication with D3-D2 partial agonism. In addition, the antidepressant dose was also increased. With the new combination, the patient reported good control of his tics, together with significant improvement in depressive symptoms and no side effects. Based on this case and the reviewed literature, cariprazine might be a viable option for patients with Tourette syndrome with other comorbid illnesses who are prone to side effects of medication.

Abstract
Tourette syndrome (TS) and chronic tic disorder (CTD) are neurological disorders of childhood onset characterized by the occurrence of tics; repetitive, purposeless, movements or vocalizations of short duration which can occur many times throughout a day. Currently, effective treatment for tic disorders is an area of considerable unmet clinical need. We aimed to evaluate the efficacy of a home-administered neuromodulation treatment for tics involving the delivery of rhythmic pulse trains of median nerve stimulation (MNS) delivered via a wearable 'watch-like' device worn at the wrist. We conducted a UK-wide parallel double-blind sham-controlled trial for the reduction of tics in individuals with tic disorder. The device was programmed to deliver rhythmic (10 Hz) trains of low-intensity (1-19 mA) electrical stimulation to the median nerve for a pre-determined duration each day, and was intended to be used by each participant in their home once each day, 5 days each week, for a period of 4 weeks. Between 18th March 2022 and 26th September 2022, 135 participants (45 per group) were initially allocated, using stratified randomization, to one of the following groups; active stimulation; sham stimulation or to a waitlist (i.e. treatment as usual) control group. Recruited participants were individuals with confirmed or suspected TS/CTD aged 12 years of age or upward with moderate to severe tics. Researchers involved in the collection or processing of measurement outcomes and assessing the outcomes, as well as participants in the active and sham groups and their legal guardians were all blind to the group allocation. The primary outcome measure used to assess the 'offline' or treatment effect of stimulation was the Yale Global Tic Severity Scale-Total Tic Severity Score (YGTSS-TTSS) assessed at the conclusion of 4 weeks of stimulation. The primary outcome measure used to assess the 'online' effects of stimulation was tic frequency, measured as the number of tics per minute (TPM) observed, based upon blind analysis of daily video recordings obtained while stimulation was delivered. The results demonstrated that after 4-week stimulation, tic severity (YGTSS-TTSS) had reduced by 7.1 points (35 percentile reduction) for the active stimulation group compared to 2.13/2.11 points for the sham stimulation and waitlist control groups. The reduction in YGTSS-TTSS for the active stimulation group was substantially larger, clinically meaningful (effect size = .5) and statistically significant (p = .02) compared to both the sham stimulation and waitlist control groups, which did not differ from one another (effect size = -.03). Furthermore, blind analyses of video recordings demonstrated that tic frequency (tics per minute) reduced substantially (-15.6 TPM) during active stimulation compared to sham stimulation (-7.7 TPM). This difference represents a statistically significant (p < .03) and clinically meaningful reduction in tic frequency (>25 percentile reduction: effect size = .3). These findings indicate that home-administered rhythmic MNS delivered through a wearable wrist-worn device has the potential to be an effective community-based treatment for tic disorders.

Abstract
Tourette Syndrome (TS) is a high-incidence multifactorial neuropsychiatric disorder characterized by motor and vocal tics co-occurring with several diverse comorbidities, including obsessive-compulsive disorder and attention-deficit hyperactivity disorder. The origin of TS is multifactorial, with strong genetic, perinatal, and immunological influences. Although almost all neurotransmettitorial systems have been implicated in TS pathophysiology, a comprehensive neurophysiological model explaining the dynamics of expression and inhibition of tics is still lacking. The genesis and maintenance of motor and non-motor aspects of TS are thought to arise from functional and/or structural modifications of the basal ganglia and related circuitry. This complex wiring involves several cortical and subcortical structures whose concerted activity controls the selection of the most appropriate reflexive and habitual motor, cognitive and emotional actions. Importantly, striatal circuits exhibit bidirectional forms of synaptic plasticity that differ in many respects from hippocampal and neocortical plasticity, including sensitivity to metaplastic molecules such as dopamine. Here, we review the available evidence about structural and functional anomalies in neural circuits which have been found in TS patients. Finally, considering what is known in the field of striatal plasticity, we discuss the role of exuberant plasticity in TS, including the prospect of future pharmacological and neuromodulation avenues.

Abstract
BACKGROUND Chronic tic disorders (CTDs) commonly co-occur with other psychiatric disorders. CTDs have been linked to functional impairment and reduction in quality of life. Insufficient research is available on depressive symptoms in patients with CTD, especially children and adolescents, yielding conflicting findings. To investigate the presence of depressive symptoms in a cohort of children and young adolescents with CTD and to test whether they moderate the link between tic severity and functional impairment. METHODS The sample consisted of 85 children and adolescents (six to 18 years) with a CTD who were treated in a large referral center. Participants were evaluated using gold-standard self- and clinician-reporting instruments to measure tic symptom severity and tic-related functional impairment (Yale Global Tic Severity Scale), depression (Child Depression Inventory), and obsessive-compulsive symptoms (Children Yale Brown Obsessive Compulsive Scale). RESULTS Depressive symptoms (mild to severe) were exhibited by 21% of our sample. Study participants with CTD and comorbid obsessive-compulsive disorder (OCD) and/or attention-deficit/hyperactivity disorder had higher rates of depressive symptoms compared with those without comorbidities. Significant correlations were found within and among all tic-related and OCD-related measures, yet depressive symptoms only correlated to tic-related functional impairment. Depression significantly and positively moderated the correlation between tic severity and tic-related functional impairment. CONCLUSIONS Findings suggest that depression plays an important part as a moderator in the link between tic severity and functional impairment in children and adolescents. Our study highlights the importance of screening for and treating depression in patients with CTD.

Abstract
Bipolar disorder is heterogeneous in phenomenology, illness trajectory, and response to treatment. Despite evidence for the efficacy of multimodal-ity interventions, the majority of persons affected by this disorder do not achieve and sustain full syndromal recovery. It is eagerly anticipated that combining datasets across various information sources (e.g., hierarchical "multi-omic" measures, electronic health records), analyzed using advanced computational methods (e.g., machine learning), will inform future diagnosis and treatment selection. In the interim, identifying clinically meaningful subgroups of persons with the disorder having differential response to specific treatments at point-of-care is an empirical priority. This paper endeavours to synthesize salient domains in the clinical characterization of the adult patient with bipolar disorder, with the overarching aim to improve health outcomes by informing patient management and treatment considerations. Extant data indicate that characterizing select domains in bipolar disorder provides actionable information and guides shared decision making. For example, it is robustly established that the presence of mixed features - especially during depressive episodes - and of physical and psychiatric comorbidities informs illness trajectory, response to treatment, and suicide risk. In addition, early environmental exposures (e.g., sexual and physical abuse, emotional neglect) are highly associated with more complicated illness presentations, inviting the need for developmentally-oriented and integrated treatment approaches. There have been significant advances in validating subtypes of bipolar disorder (e.g., bipolar I vs. II disorder), particularly in regard to pharmacological interventions. As with other severe mental disorders, social functioning, interpersonal/family relationships and internalized stigma are domains highly relevant to relapse risk, health outcomes, and quality of life. The elevated standardized mortality ratio for completed suicide and suicidal behaviour in bipolar disorder invites the need for characterization of this domain in all patients. The framework of this paper is to describe all the above salient domains, providing a synthesis of extant literature and recommendations for decision support tools and clinical metrics that can be implemented at point-of-care.

Suh HW, Yoon SI, Hong S, Lee HW, Lee M, Kim JW, Chung SY. How do children with Tourette's syndrome and their caregivers live with the disorder? A systematic review of qualitative evidence. Front Psychiatry 2022; 13:992905. [PMID: 36245875 PMCID: PMC9557735 DOI: 10.3389/fpsyt.2022.992905] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2022] [Accepted: 09/12/2022] [Indexed: 11/13/2022] Open
Abstract
Background Tourette's syndrome (TS) is a childhood neurodevelopmental disorder characterized by sudden, repetitive, involuntary, and irregular muscle movement and vocalization. Recently, non-pharmaceutical methods, such as behavioral therapy, psychotherapy, and deep brain stimulation, have been introduced as alternatives to pharmacological treatment for TS. This study aimed to systematically review and synthesize qualitative evidence on the experiences of children with TS and their caregivers. A meta-synthesis of qualitative evidence could help provide a comprehensive understanding of the challenges experienced by children with TS and their caregivers with the aim of providing more effective treatment and services for them. Materials and methods A systematic search was conducted using MEDLINE/PubMed, EMBASE, Cumulative Index to Nursing and Allied Health Literature, PsycARTICLES, and three Korean databases (Korean Medical Database, Research Information Sharing Service, and ScienceON) in July 2021. Studies were included if they collected and analyzed qualitative data from children with tic disorder or TS, or their caregivers. Qualitative research findings on the experiences and perspectives of children with TS and their caregivers were critically appraised and synthesized using the Joanna Briggs Institute methodology. Results Eight eligible studies were included. The findings from these studies (i.e., themes or subthemes of qualitative research) were aggregated into categories (a group of similar findings) and synthesized findings (a group of categorized findings). Ultimately, the 60 findings were aggregated into 15 categories. Finally, four synthesized findings were derived from the 15 categories: (i) continuation of challenging daily life, (ii) denying that TS causes emotional distress, (iii) accepting and understanding TS as part of oneself, and (iv) looking to the future. Conclusion Children with TS and their caregivers experience physical and psychological distress and social deprivation. Avoiding and suppressing TS causes secondary distress such as guilt. However, seeking social support and accepting the disorder reduce the distress caused by symptoms and lays the foundation for later growth. Even in the face of adversity, children with TS and their caregivers find personal value and acquire a more open and optimistic attitude toward life. This review shows that acceptance-based therapy and social support should be provided for the treatment and management of TS.

Abstract
OBJECTIVE Tourette syndrome (TS) is a childhood neurodevelopmental disorder caused by various genetic and environmental factors and presents with apparent genetic heterogeneity. As ASH1L potentially contributes to neurodevelopmental diseases, especially in TS, we aim to investigate the susceptibility of ASH1L on TS in the Chinese Han population. METHODS Three tag single nucleotide polymorphisms (SNPs) (rs5005770, rs12734374, and rs35615695) in ASH1L were screened in 271 TS nuclear family trios and 337 healthy subjects by the TaqMan assays real time. A case-control study combined with family-based analysis was applied to study the genetic susceptibility of common variants of ASH1L. RESULTS The results revealed a significant over-transmission of rs35615695 and rs5005770 (for rs35615695, transmission disequilibrium test, χ2 = 57.375, p = .000, HHRR, χ2 = 4.807, p = .028; for rs5005770, HRR, χ2 = 4.116, p = .042, HHRR, χ2 = 8.223, p = .004) in family-based study. Furthermore, rs5005770 and rs35615695 still remained significant after Bonferroni correction (p < .017). However, the two SNPs (rs5005770 and rs35615695) were found not to be associated with TS in case-control study. CONCLUSIONS Our study suggests that ASH1L may contribute to TS susceptibility in the Han Chinese population and involved in TS development as a risk factor.

Abstract
Abstract
Objective
To better understand current practices of U.S.-based physicians in the management of Tourette syndrome (TS) and identify gaps that may be addressed by future education.
Methods
Two survey instruments were developed to gather data on management of TS and perceptions from physicians and caregivers of children with TS. The clinician survey was developed in consultation with a TS physician expert and utilized clinical vignettes to assess and quantify practice patterns. The caregiver survey was adapted from the clinician survey and other published studies and gathered details on diagnosis, treatment, and perceptions regarding management.
Results
Data included responses from 138 neurologists (including 57 pediatric neurologists), 162 psychiatrists (including 42 pediatric psychiatrists), and 67 caregivers. Most (65%) pediatric neurologists rely solely on clinical findings to make a diagnosis, whereas the majority of other specialists utilize additional testing (eg, neuroimaging, lab testing, and genetics). Most psychiatrists (96%) utilize standardized criteria to make a diagnosis, whereas 22% of neurologists do not. Many physicians (44% of psychiatrists and 20% of neurologists) use pharmacotherapy to treat a patient with “slightly bothersome” tics and no functional impairment, whereas caregivers favored behavioral therapy. Most (76%) caregivers preferred to make the final treatment decision, whereas 80% of physicians preferred equal or physician-directed decision-making.
Conclusions
This study provides insight into practice patterns and perceptions of U.S.-based neurologists and psychiatrists in managing TS. Results highlight the potential value of physician education, including diagnostic approach, tic management and monitoring, involvement of caregivers in decision-making, and updates on TS management.

Abstract
BACKGROUND Specific health-risk behaviors are present in older adolescents and young adults wtih Tourette syndrome (TS), but little is known about health-risk behaviors in youth with TS. METHODS We compared responses on the Youth Risk Behavior Surveillance System (YRBS) in youth with TS with those in a concurrent community control group. The YRBS evaluates risk behaviors most closely associated with morbidity and mortality in young people. Tic severity, presence of comorbid attention-deficit/hyperactivity disorder (ADHD), measures of ADHD symptom severity, and whether or not the individual had been bullied in school were also compared between the groups. RESULTS Data from 52 youth with TS and 48 control youth were included. We did not detect any differences between control youth and youth with TS in the reporting of risky behaviors. Tic severity was not significantly associated with high-risk behavior. However, ADHD was significantly more common in youth with TS (P < 0.0002), and youth with TS who identified themselves as victims of bullying had significantly higher ADHD symptom severity scores (P = 0.04) compared with those who were not bullied. CONCLUSIONS Risk behaviors are not reliably or clinically different in youth with TS compared with control youth. ADHD severity, but not tic severity, was associated with being bullied in youth with TS.

"I'm in pain and I want help": An online survey investigating the experiences of tic-related pain and use of pain management techniques in people with tics and tic disorders. Front Psychiatry 2022; 13:914044. [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
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.

Abstract
Tourette syndrome (TS) causes academic, social, emotional, physical, and functional problems. Most TS patients also have comorbid neuropsychological conditions. The purpose of this review is to provide updated information to the clinician about phenomenology, epidemiology, comorbidities, pathophysiology and management strategies for tics (a hallmark of TS) and TS. Recent findings suggest that TS is likely due to a combination of several different genes and environmental factors, with possible involvement of the cortical-basal ganglia-thalamocortical circuit and related multiple neurotransmitters. First-line management includes psychoeducation for families, patients, and school personnel, as well as behavioral therapy. Non-medicine treatment for tics is advancing to include younger children and increase access via remote service applications. Pharmacotherapy is used if appropriate and several new medicines are under investigation (e.g., Tetrabenazine, valbenazine, deutetrabenazine, ecopipam, cannabinoids). Deep brain stimulation and Mouthguard therapy can be used for children with intractable illness.

Abstract
BACKGROUND Tic disorders are childhood-onset neuropsychiatric disorders characterized by multiple motor or vocal tics with frequent comorbidities and a broad spectrum of phenotypic presentations. In this study, we aimed to investigate the clinical characteristics and comorbid neuropsychiatric conditions in pediatric patients with tic disorders. METHODS We retrospectively reviewed the medical records of 119 pediatric patients (89 males, 30 females) who were diagnosed with tic disorders according to the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) at Uijeongbu St. Mary's Hospital, Republic of Korea, between January 2012 and July 2019. RESULTS The mean age of tic onset was 6.9 years (range, 1-14) and the mean age at diagnosis was 8 years (range, 1-17). The mean lag between tic onset and diagnosis was 13.3 months (range, 0.25-132). The most common, first-presenting tics were eye blinking (50.4%), followed by jaw or lip movement (29.4%) and throat clearing (29.4%). Thirty-seven (31.1%) patients had at least one co-occurring neuropsychiatric disorder at the time of tic diagnosis. Subtypes of tic disorders, types of initial tics, and presence of neuropsychiatric comorbidities were not associated with tic severity. Tic severity was associated with greater functional impairment and tic noticeability (p < 0.05). A relatively shorter time to diagnosis was associated with tic severity (Spearman's ρ = - 0.14, p = 0.11). CONCLUSIONS The evolving nature of tic expression and severity, high prevalence of neuropsychiatric comorbidities, and associated functional impairments emphasize the importance of comprehensive assessment during the disease course for determining and prioritizing goals of treatment.

Abstract
Ash1l potentially contributes to neurodevelopmental diseases. Although specific Ash1l mutations are rare, they have led to informative studies in animal models that may bring therapeutic advances. Ash1l is highly expressed in the brain and correlates with the neuropathology of Tourette syndrome (TS), autism spectrum disorder, and intellectual disability during development, implicating shared epigenetic factors and overlapping neuropathological mechanisms. Functional convergence of Ash1l generated several significant signaling pathways: chromatin remodeling and transcriptional regulation, protein synthesis and cellular metabolism, and synapse development and function. Here, we systematically review the literature on Ash1l, including its discovery, expression, function, regulation, implication in the nervous system, signaling pathway, mutations, and putative involvement in TS and other neurodevelopmental traits. Such findings highlight Ash1l pleiotropy and the necessity of transcending a single gene to complicated mechanisms of network convergence underlying these diseases. With the progress in functional genomic analysis (highlighted in this review), and although the importance and necessity of Ash1l becomes increasingly apparent in the medical field, further research is required to discover the precise function and molecular regulatory mechanisms related to Ash1l. Thus, a new perspective is proposed for basic scientific research and clinical interventions for cross‐disorder diseases.

Abstract
Current knowledge on the general somatic health and causes of death in Tourette syndrome and chronic tic disorder is very limited. Here, we review the available literature on the topic, while highlighting strengths and weaknesses of the studies conducted to date. These previous works have suggested associations between Tourette syndrome and chronic tic disorder and a range of health conditions, including autoimmune disorders, common allergies and respiratory diseases, sleep difficulties, and metabolic and cardiovascular outcomes. Additionally, the risk of mortality in tic disorders might be higher than that of the general population, but specific causes of death have rarely been studied, except for substance use-related deaths and suicide, which are significantly higher in individuals with Tourette syndrome and chronic tic disorder. Many of these emerging findings require replication and extension but, taken together, they suggest that that it might be sensible to monitor the general health and suicide risk of individuals with Tourette syndrome or chronic tic disorder across the lifespan. We suggest further avenues for research on this topic.

Abstract
OBJECTIVE Tourette syndrome is a neurodevelopmental disorder putatively associated with a hyperdopaminergic state. Therefore, it seems plausible that excessive dopamine transmission in Tourette syndrome alters the ability to learn based on rewards and punishments. We tested whether Tourette syndrome patients exhibited altered reinforcement learning and corresponding feedback-related EEG deflections. METHODS We used a reinforcement learning task providing factual and counterfactual feedback in a sample of 15 Tourette syndrome patients and matched healthy controls whilst recording EEG. The paradigm presented various reward probabilities to enforce adaptive adjustments. We employed a computational model to derive estimates of the prediction error, which we used for single-trial regression analysis of the EEG data. RESULTS We found that Tourette syndrome patients showed increased choice stochasticity compared to controls. The feedback-related negativity represented an axiomatic prediction error for factual feedback and did not differ between groups. We observed attenuated P3a modulation specifically for factual feedback in Tourette syndrome patients, representing impaired coding of attention allocation. CONCLUSION Our findings indicate that cortical prediction error coding is unaffected by Tourette syndrome. Nonetheless, the transfer of learned values into choice formation is degraded, in line with a hyperdopaminergic state.

Abstract
Tourette syndrome is a multifaceted disorder characterized by multiple motor and at least one vocal tics that start in childhood, persist for at least 1 year, and cannot be attributed to another medical condition or exposure to medications/drugs. Clinical diagnostic criteria are available, and identification of tics is typically straightforward based on characteristic appearance and features. Diagnostic uncertainty can rarely arise in cases of mild tics, atypical features, certain psychiatric comorbidities, and other non-tic movement disorders. Comorbid psychopathology, including attention-deficit hyperactivity disorder (ADHD) and obsessive-compulsive behaviors/obsessive-compulsive disorder, affects the majority of patients and is correlated with disease severity and the presence of additional psychiatric behaviors. The severity of tics often improves after adolescence, whereas psychiatric symptoms typically persist. The subset of patients in whom tics persist into adulthood experience higher rates of anxiety, and lower self-esteem, socioeconomic status, and quality of life; the relative contribution of motor tics and psychopathology is not fully understood. This article summarizes the clinical features of Tourette syndrome, including major diagnostic criteria, unique features of tics, and key aspects that differentiate tics from common mimics and chameleons. Comorbid psychiatric conditions and their impact on phenotype and quality of life are described. Finally, current understanding of the natural history is summarized, including limited research in adults with Tourette syndrome.

Abstract
Tic disorders are neurodevelopmental disorders characterised by the presence of motor or phonic tics, or both. Patients with tic disorders commonly report premonitory urges of tics. Alexithymia is a psychological trait characterised by a difficulty in identifying and expressing one's own feelings and by an externally oriented thinking. We aimed to explore alexithymia in children with tic disorders and in their mothers. Global alexithymia scores of both children with tic disorders and of their mothers did not differ from those of the participants from the control group. In the tic disorder group, however, both children and their mothers showed a cognitive style characterised by operational thinking and a lack of imaginative abilities. The mothers of children with tic disorder reported significantly higher parental stress. Alexithymia was not predictive of tic severity but was predictive of the severity of the premonitory urges. The implications of these findings are discussed.

Abstract
INTRODUCTION Tourette syndrome (TS) is a neurodevelopmental disorder with a high prevalence of psychiatric comorbidity. The most common comorbid disorder in patients with TS is attention-deficit/hyperactivity disorder (ADHD). To date, there have been few reports concerning the association of TS with addiction. METHODS We report on 4 patients with TS, ADHD, and heroin addiction. RESULTS All 4 patients were male and initially presented with TS when they were between 5 and 12 years of age, although 2 of the patients were not diagnosed with TS until they were adults. The patients currently range in age from 21 to 52 years, all having experienced the onset of heroin addiction in adolescence. A reduction in tics during periods of heroin abuse was noted in all patients. DISCUSSION The lifetime prevalence of psychiatric comorbidity in patients with TS is 85.7%, with 57.7% of patients having ≥2 psychiatric conditions in addition to TS. All of the 4 patients in our case series demonstrated a pattern of severe tics, ADHD, impulsive behavior, and heroin addiction. Our observation that these 4 patients with TS showed reduced tics during periods of heroin dependence could be related to the previously described effects of opiates on dopaminergic transmission. CONCLUSIONS The observed reduction of tics during heroin dependence warrants further clinical research.

Abstract
BACKGROUND Tourette syndrome (TS) and chronic tic disorders (CTD) are stigmatizing disorders that may significantly impact self-esteem. Alternatively, comorbid psychiatric illnesses may affect self-esteem more than tics themselves. Extant research on self-esteem in TS/CTD is limited, has inconsistently examined the effect of comorbidities on self-esteem, and yields mixed findings. METHOD This study aimed to clarify the roles of tics versus comorbid diagnoses on self-esteem in a large, carefully diagnosed sample of adults with TS/CTD (N = 122) receiving 10 weeks of Comprehensive Behavioral Intervention for Tics (CBIT) or Psychoeducation and Supportive Therapy (PST). RESULTS Baseline self-esteem did not differ between adults with TS/CTD only and normative means, whereas self-esteem was significantly lower among adults with TS/CTD with a comorbid psychiatric illness. In a multiple regression testing the baseline association between tic severity, presence of comorbid psychiatric illness, and depression severity with self-esteem, comorbidity and depression severity were significantly associated with self-esteem, whereas tic severity was not. Finally, using a generalized linear model, we tested the effects of treatment assignment, comorbidity, and their interaction on changes in self-esteem across treatment, controlling for baseline depression severity. Results showed that for those with a comorbid illness, self-esteem improved significantly more with CBIT than with PST. CONCLUSIONS Comorbid illnesses appear to affect self-esteem more so than tics among adults with TS/CTD. Therapeutic attention should be paid to treating comorbid diagnoses alongside tics when treating TS/CTD.

Abstract
Gilles de la Tourette syndrome is a chronic and complex tic disorder accompanied by specific behavioral problems in the majority of patients. With its multifaceted interplay between motion and emotion, this condition is a paradigmatic example of the science and art of clinical neuropsychiatry. This review article encompasses the clinical phenomenology of motor and vocal tics and associated sensory experiences (premonitory urges), as well as the behavioral spectrum of the most common comorbidities, including obsessive-compulsive disorder, attention-deficit and hyperactivity disorder, affective symptoms, and impulsivity. Knowledge of the contributions of both tics and behavioral problems to patients' health-related quality of life across the lifespan should assist treating clinicians in formulating a targeted management plan. Although the exact pathophysiology of Gilles de la Tourette syndrome remains elusive, research into therapeutic interventions has expanded the range of available interventions across multiple domains. A thorough understanding of the neurology and psychiatry of this condition is of key importance to meet the needs of this patient population, from the formulation of an accurate diagnosis to the implementation of effective treatment strategies.

Abstract
OBJECTIVE Depression is common in Tourette syndrome and Chronic Tic Disorders (TS/CTD) and contributes to significant impairment. The specificity of autobiographical memories is implicated in an individual's sense of self and their daily functioning but also in the onset and development of depression in the general population. Here, we examined whether memory specificity is reduced in young people with TS/CTD, relative to control participants, and whether memory specificity is associated with depression. METHOD Thirty young people with TS/CTD (14 females; age: x̅ = 11.31; SD = 1.66; 87% White British) and twenty-six (12 females; age: x̅ = 11.23; SD = 2.43; 77% White British) control participants completed the study. Participants completed the Autobiographical Memory Task, which asks participants to respond with a specific memory to cue words, and a questionnaire measure of depressive symptoms. RESULTS There was no significant difference between the two groups in terms of age, gender, ethnicity, IQ and depressive symptomatology. Young people with TS/CTD had less specific autobiographical memories than their peers (p < 0.001, r = 0.49). Across both groups, increased memory specificity for positive cue words was associated with reduced depressive symptomatology (p < 0.001, R2 = 0.51). CONCLUSIONS Our findings indicate that autobiographical memory in young people with TS is characterised by a lack of specificity and, as with neurotypical peers, reduced memory specificity for positive words is associated with depressive symptoms. Autobiographical memory specificity could be an important factor in understanding mood symptoms that characterise young people with TS/CTD and may be an important cognitive target to reduce the development of depression in young people with TS/CTD.

Abstract
Psychiatric comorbidities are common in movement disorders. This review provides a practical approach to help clinicians to recognize psychiatric disorders in the most frequent movement disorders. However, the extent of neurodegeneration, as well as the impact of medications with considerable CNS effects, influences the diverse psychiatric presentations that, in turn, are influenced by the stress of living with a movement disorder. Depression, anxiety, and psychosis are the most common psychiatric comorbidities in movement disorders and of the medications used to treat the motor disturbances. These psychiatric problems impair patients' functioning throughout the course of the chronic neurodegenerative diseases. Due to the direct connection between brain dysfunction and psychiatric symptoms, there is hope that understanding the psychiatric comorbidities in movement disorders will lead to a better quality-of-life.

Abstract
In the past two decades, ethnographic, epidemiological and interdisciplinary research has robustly established that culture is significant in determining the long-term outcomes of people with neurodevelopmental, neuropsychiatric and mood disorders. Yet these cultural factors are certainly not uniform across discrete individual experiences. Thus, in addition to illustrating meaningful differences for people with neuropsychiatric disorder between different cultures, ethnography should also help detail the variations within a culture. Different subjective experiences or outcomes are not solely due to biographical idiosyncrasies-rather, influential factors arising from the same culture can have different impacts on different people. When taking a holistic and intersectional perspective on lived experience, it is crucial to understand the interaction of these factors for people with neuropsychiatric disorders. This paper teases apart such interactions, utilizing comparative case studies of the disparate subjective experiences and illness trajectories of two Balinese people with Tourette syndrome who exhibit similar symptoms. Based on longitudinal person-centered ethnography integrating clinical, psychological, and visual anthropology, this intersectional approach goes beyond symptom interpretation and treatment modalities to identify gendered embodiment and marital practices as influenced by caste to be significant determinants in subjective experience and long-term outcome.

Abstract
BACKGROUND Persons with neuropsychiatric disorders are at increased risk of suicide, but there is little data concerning Tourette's and chronic tic disorders (TD/CTD). We aimed to quantify the risk of suicidal behavior in a large nationwide cohort of patients with TD/CTD, establish the contribution of psychiatric comorbidity to this risk, and identify predictors of suicide. METHODS Using a validated algorithm, we identified 7736 TD/CTD cases in the Swedish National Patient Register during a 44-year period (1969-2013). Using a matched case-cohort design, patients were compared with general population control subjects (1:10 ratio). Risk of suicidal behavior was estimated using conditional logistic regressions. Predictors of suicidal behavior in the TD/CTD cohort were studied using Cox regression models. RESULTS In unadjusted models, TD/CTD patients, compared with control subjects, had an increased risk of both dying by suicide (odds ratio: 4.39; 95% confidence interval [CI]: 2.89-6.67) and attempting suicide (odds ratio: 3.86; 95% CI: 3.50-4.26). After adjusting for psychiatric comorbidities, the risk was reduced but remained substantial. Persistence of tics beyond young adulthood and a previous suicide attempt were the strongest predictors of death by suicide in TD/CTD patients (hazard ratio: 11.39; 95% CI: 3.71-35.02, and hazard ratio: 5.65; 95% CI: 2.21-14.42, respectively). CONCLUSIONS TD/CTD are associated with substantial risk of suicide. Suicidal behavior should be monitored in these patients, particularly in those with persistent tics, history of suicide attempts, and psychiatric comorbidities. Preventive and intervention strategies aimed to reduce the suicidal risk in this group are warranted.

Abstract
INTRODUCTION Gilles de la Tourette syndrome (GTS) is a childhood-onset neuropsychiatric disorder characterised by multiple tics and often associated with behavioural problems. Although there is evidence of significantly reduced self-esteem in children and adolescents with GTS, little is known about perceived self-concept and its clinical determinants at the transition age between adolescence and adulthood. We therefore set out to investigate self-concept in a clinical sample of young patients with GTS at this crucial age for personal development. METHODS In addition to standard demographic and clinical data, we collected self-ratings using a standardised battery of psychometric instruments, as well as the Multidimensional Self Concept Scale, a comprehensive questionnaire developed to assess self-concept in subjects aged 9- to 19 years, tapping into the social, competence, affect, academic, family, and physical domains. RESULTS We found that patients diagnosed with at least one co-morbid psychiatric disorder ("GTS-plus" phenotype) reported significantly lower self-concept than patients with "pure GTS", whereas tic-related variables had no impact on self-concept. Anxiety symptoms were the main determinants of self-concept, especially trait anxiety with regard to social and affective domains. Affective symptoms could also have a negative impact on the physical, affective, competence, and social domains of self-concept. CONCLUSION Routine screening for anxiety and affective symptoms should be recommended in all patients with GTS seen at transition clinics from paediatric to adult care, in order to implement effective treatment interventions whenever possible.

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
Deep brain stimulation (DBS) may be considered in severe cases of therapy‐refractory major depressive disorder (MDD). However, DBS for MDD is still an experimental therapy. Therefore, it should only be administered in clinical studies driven by multidisciplinary teams, including surgeons with substantial experience of DBS in the treatment of other conditions.

Abstract
BACKGROUND Tic disorders, including Tourette syndrome, are complex, multisymptom diseases, yet the impact of these disorders on affected children, families, and communities is not well understood. METHODS To improve the understanding of the impacts of Tourette syndrome, two research groups conducted independent cross-sectional studies using qualitative and quantitative measures. They focused on similar themes, but distinct scientific objectives, and the sites collaborated to align methods of independent research proposals with the aim of increasing the analyzable sample size. RESULTS Site 1 (University of Rochester) was a Pediatric Neurology referral center. Site 2 (University of South Florida) was a Child Psychiatry referral center. A total of 205 children with tic disorders were enrolled from both studies. The University of Rochester also enrolled 100 control children in order to clearly isolate impacts of Tourette syndrome distinct from those occurring in the general population. The majority of children with tic disorders (n = 191, 93.1%) had Tourette syndrome, the primary population targeted for these studies. Children with Tourette syndrome were similar across sites in terms of tic severity and the occurrence of comorbid conditions. The occurrence of psychiatric comorbidities in the control group was comparable with that in the general pediatric population of the United States, making this a well-justified comparison group. CONCLUSIONS Through collaboration, two sites conducting independent research developed convergent research methods to enable pooling of data, and by extension increased power, for future analyses. This method of collaboration is a novel model for future epidemiological research of tic disorders.

Abstract
Gilles de la Tourette syndrome (GTS) is a childhood-onset neurodevelopmental disorder that is characterized by several motor and phonic tics. Tics usually develop before 10 years of age, exhibit a waxing and waning course and typically improve with increasing age. A prevalence of approximately 1% is estimated in children and adolescents. The condition can result in considerable social stigma and poor quality of life, especially when tics are severe (for example, with coprolalia (swearing tics) and self-injurious behaviours) or when GTS is accompanied by attention-deficit/hyperactivity disorder, obsessive-compulsive disorder or another neuropsychiatric disorder. The aetiology is complex and multifactorial. GTS is considered to be polygenic, involving multiple common risk variants combined with rare, inherited or de novo mutations. These as well as non-genetic factors (such as perinatal events and immunological factors) are likely to contribute to the heterogeneity of the clinical phenotype, the structural and functional brain anomalies and the neural circuitry involvement. Management usually includes psychoeducation and reassurance, behavioural methods, pharmacotherapy and, rarely, functional neurosurgery. Future research that integrates clinical and neurobiological data, including neuroimaging and genetics, is expected to reveal the pathogenesis of GTS at the neural circuit level, which may lead to targeted interventions.

Abstract
Motor and vocal tics are relatively common motor manifestations identified as the core features of Tourette's syndrome (TS). Although traditional descriptions have focused on objective phenomenological observations, such as anatomical location, number and frequency of tics, patients' first-person accounts have consistently reported characteristic subjective correlates. These sensory phenomena are often described as a feeling of mounting inner tension or urge to move ("premonitory urge"), which is transiently relieved by tic expression. This article reviews the existing literature on the clinical and neurobiological aspects of the premonitory urge in patients with TS, with focus on its pathophysiology and possible treatment implications.

Abstract
BACKGROUND γ-Aminobutyric acid has been implicated in the pathophysiology of Tourette's disorder. The present study primarily sought to examine in vivo γ-aminobutyric acid levels in the anterior cingulate cortex in psychotropic medication-free adolescents and young adults. Secondarily, we sought to determine associations between γ-aminobutyric acid in the anterior cingulate cortex and measures of tic severity, tic-related impairment, and anxiety and depression symptoms. METHODS γ-Aminobutyric acid levels were measured using proton magnetic resonance spectroscopy. Analysis of covariance compared γ-aminobutyric acid levels in 15 youth with Tourette's disorder (mean age = 15.0, S.D. = 2.7) and 36 healthy comparison subjects (mean age = 15.9, S.D. = 2.1). Within the Tourette disorder group, we examined correlations between γ-aminobutyric acid levels and tic severity and tic-related impairment, as well as anxiety and depression severity. RESULTS Anterior cingulate cortex γ-aminobutyric acid levels were lower in participants with Tourette's disorder compared with control subjects. Within the Tourette disorder group, γ-aminobutyric acid levels did not correlate with any clinical measures. CONCLUSIONS Our findings support a role for γ-aminobutyric acid in Tourette's disorder. Larger prospective studies will further elucidate this role.

Abstract
Tourette syndrome is a neuropsychiatric condition characterized by both motor and phonic tics over a period of at least 1 year with the onset in childhood or adolescence. Apart from the tics, most of the patients with Tourette syndrome have associated neuropsychiatric comorbidities consisting of attention deficit hyperactivity disorder, obsessive compulsive disorder, rage attacks, sleep issues, depression, and migraine. Patients may also have physical complications directly from violent motor tics which can rarely include cervical myelopathy, arterial dissection, and stroke. The purpose of this article is to review the associated neuropsychiatric comorbidities of Tourette syndrome with emphasis on recent research.

Abstract
High-frequency stimulation (HFS) of the subthalamic nucleus (STN) is often used to treat movement disability in advanced Parkinson's disease, but some patients experience debilitating psychiatric effects including depression. Interestingly, HFS of the STN modulates 5-HT neurons in the dorsal raphe nucleus (DRN) which are linked to depression, but the neural substrate of this effect is unknown. Here, we tested the effect of STN stimulation on neuronal activity in the lateral habenula nucleus (LHb), an important source of input to DRN 5-HT neurons and also a key controller of emotive behaviours. LHb neurons were monitored in anaesthetized rats using single-unit extracellular recording, and localization within the LHb was confirmed by juxtacellular labelling. HFS of the STN (130 Hz) evoked rapid changes in the firing rate of the majority of LHb neurons tested (38 of 68). Some LHb neurons (19/68) were activated by HFS, while others (19/68), distinguished by a higher basal firing rate, were inhibited. LHb neurons that project to the DRN were identified using antidromic activation and collision testing (n = 17 neurons). Some of these neurons (5/17) were also excited by HFS of the STN, and others (7/17) were inhibited although this was only a statistical trend. In summary, HFS of the STN modulated the firing of LHb neurons, including those projecting to the DRN. The data identify that the STN impacts on the LHb-DRN pathway. Moreover, this pathway may be part of the circuitry mediating the psychiatric effects of STN stimulation experienced by patients with Parkinson's disease.

Abstract
OBJECTIVE The current study evaluated the relationship between tic, sleep disorders and specific psychiatric symptoms (anxiety, depression, obsessive compulsive symptoms). METHODS Assessment of 36 consecutive children and adolescents with tic disorders included: the Yale Global Tic Severity Scale (YGTSS) to assess the severity of tic symptoms; the Self-administered scale for children and adolescents (SAFA) to evaluate the psychopathological profile; a specific sleep questionnaire consisting of 45 items to assess the presence of sleep disorders. An age and sex-matched control group was used for comparisons. RESULTS Sleep was significantly more disturbed in patients with tic disorders than in controls. Difficulties in initiating sleep and increased motor activity during sleep were the most frequent sleep disturbances found in our sample. Patients showed also symptoms of anxiety (SAFA A), depressed mood (SAFA D) and doubt-indecision (SAFA O). Additionally, difficulties in initiating sleep resulted associated with other SAFA subscales relative to obsessive-compulsive symptoms and depression symptoms. Furthermore, anxiety symptoms (SAFA A) resulted associated with increased motor activity during sleep. CONCLUSIONS Findings confirm literature studies reporting high frequency of sleep problems, anxiety and other psychopathological symptoms in patients with tic disorders, and support the hypothesis that intrusive thoughts and other emotional disturbances might disrupt the sleep onset of these patients. These results suggest the importance of a thorough assessment of sleep and psychiatric disturbances in patients with tic disorders.

Abstract
BACKGROUND This study examined the incidence and clinical correlates of suicidal ideation (SI) in youth with tic disorders (TD). The independent contribution of tics, anxiety, depressive and externalizing symptoms on SI severity in youth with TD was assessed. METHOD Participants were 75 treatment-seeking youth with a TD (N=75) aged 6-18. Participants completed diagnostic assessments, clinician-ratings, self- and parent-report measures of emotional functioning and the presence and/or severity of suicidal ideation. RESULTS Based on youth-report, 61% of youth endorsed at least some symptoms of SI, and 8% endorsed symptoms that exceeded the clinically significant cut-off. Parents reported SI in 11% of cases, with generally poor agreement between parent- and youth-report. Suicidal ideation correlated with higher anxiety, depressive and externalizing symptoms, affective lability, and with poorer distress tolerance and overall functioning. Anxiety, depressive and externalizing symptoms showed an independent relationship with SI. Tic severity was not associated with SI. Rather, higher tic severity was associated with an increase in anxiety symptoms, which in turn, was associated with greater SI severity. LIMITATIONS Cross-sectional data limits causal conclusions. Diagnosis was based on unstructured assessments by expert clinicians, including consensus diagnosis, rather than structured clinical interviews. CONCLUSIONS Around 8-11% of youth with TD experienced SI. Tic severity did not have any direct influence on SI, however the presence of comorbid anxiety and depressive symptoms significantly increases this risk. Results suggest that it is psychiatric comorbidity, rather than tics themselves, that predispose youth with tic disorders to increased risk of suicidality.

Abstract
There is emerging evidence for talking therapies in the treatment of tic disorders. This study explored experiences of young people who self-identified as having had a successful or helpful talking therapy, in order to understand the phenomenology, value and meaning of outcomes. The experiences of seven participants aged 10–17 years were described in semi-structured interviews and analysed using Interpretative Phenomenological Analysis. Themes included the challenging battle with tics and process of re-defining self-identity, making sense of and managing experiences, the value of control, and spectrum of positive change. The results highlighted valued outcomes that could be incorporated into clinical practice and future evaluation.

Abstract
Tourette syndrome (TS) is more than having motor and vocal tics, and this review will examine the varied comorbidities as well as the social impact and quality of life (QoL) in individuals with TS. The relationship between any individual and his/her environment is complex, and this is further exaggerated in the case of a person with TS. For example, tics may play a significant role in shaping the person's experiences, perceptions, and interactions with the environment. Furthermore, associated clinical features, comorbidities, and coexisting psychopathologies may compound or alter this relationship. In this regard, the common comorbidities include attention-deficit hyperactivity disorder and disruptive behaviors, obsessive compulsive disorder, and autism spectrum disorder, and coexistent problems include anxiety, depression, and low self-esteem, which can all lead to poorer psychosocial functioning and QoL. Thus, the symptoms of TS and the associated comorbid conditions may interact to result in a vicious cycle or a downward spiraling of negative experiences and poor QoL. The stigma and social maladjustment in TS and the social exclusion, bullying, and discrimination are considered to be caused in large part by misperceptions of the disorder by teachers, peers, and the wider community. Improved community and professional awareness about TS and related comorbidities and other psychopathologies as well as the provision of multidisciplinary services to meet the complex needs of this clinical population are critical. Future research to inform the risk and resilience factors for successful long-term outcomes is also warranted.

Abstract
BACKGROUND Tourette syndrome (TS) is a neurodevelopmental condition characterised by multiple tics and co-morbid behavioural problems. Previous research found that up to 76% of patients with TS experience affective symptoms, with 13% fulfilling diagnostic criteria for depression. OBJECTIVES We aimed to assess the severity of depression and profile of depressive symptoms in adult patients with TS compared to patients with major depression and healthy controls. METHODS Depression ratings were collected from patients with TS (N=65) using the BDI-II and from patients with recurrent major depressive disorder (rMDD, N=696) and healthy controls (N=293) using the Beck Depression Inventory (BDI)-IA. Direct comparisons were possible for 14/21 BDI items. RESULTS Patients with TS scored significantly higher on the BDI than controls (P<0.001) and all individual symptoms were reported more frequently by patients with TS than by controls (P<0.001). Total BDI score in TS was not significantly different to that in rMDD, however irritability was significantly more frequently reported in the TS group and this remained significant after controlling for age and gender differences between the two groups (OR 5.24, 95% CI 1.97-14.00; P=0.001). CONCLUSIONS Our findings show that depression is a prominent feature in TS and may present with a more irritable phenotype than rMDD. Patients with TS should be routinely screened for depression to implement treatment as appropriate.
