Abstract
Gilles de la Tourette's syndrome is an uncommon illness associated with repetitive un-voluntary abnormal movements and utterance. It is often associated with other psychiatric morbidities. Management requires awareness of this uncommon illness, keen observation, relevant evaluation, and combination of pharmacology and psychotherapy for an optimal outcome. This case is brought out here for florid presentation and nuances of management.

Abstract
Tourette's syndrome (TS) is a neuropsychiatric disorder of childhood onset characterized by multiple motor and phonic tics that fluctuate over time. Tic symptoms often improve by late adolescence, but some children and adults with TS may experience significant tic-related morbidity, including social and family problems, academic difficulties, and pain. When more conservative interventions are not successful, and when certain psychiatric co-morbidities further complicate the clinical profile, treating TS with an atypical antipsychotic medication may be a reasonable second-tier approach. However, the evidence supporting efficacy and safety of the atypical antipsychotics for treatment of tics is still very limited. The objective of this paper is to provide an updated overview of the role of atypical antipsychotics for treatment of TS, with evidence-based guidance on their use. Evidence for efficacy of different typical and atypical antipsychotics for treatment of tics was examined by conducting a systematic, keyword-related search of 'atypical antipsychotics' and 'Tourette's syndrome' in PubMed (National Library of Medicine, Washington, DC, USA). Four recent treatment consensus publications were also reviewed. This review focused on literature published from 2000 to 2013 and on available randomized controlled trials in TS. Evidence supporting the use of atypical antipsychotics for treatment of TS is limited. There are few randomized medication treatment trials in TS (i.e. risperidone, aripiprazole, ziprasidone), which employed varying methodologies, thereby restricting meaningful comparisons among studies. Future collaborations among clinical sites with TS expertise employing high-quality study design may better elucidate the role of atypical antipsychotics for treatment of TS.

Abstract
Tourette syndrome (TS) is a childhood-onset neurodevelopmental disorder characterized by multiple motor tics and at least one vocal or phonic tic, and often one or more comorbid psychiatric disorders. Premonitory sensory urges before tic execution and desire for "just-right" perception are central features. The pathophysiology involves cortico-striato-thalamo-cortical circuits and possibly dopaminergic system. TS is considered a genetic disorder but the genetics is complex and likely involves rare mutations, common variants, and environmental and epigenetic factors. Treatment is multimodal and includes education and reassurance, behavioral interventions, pharmacologic, and rarely, surgical interventions.

Abstract
BACKGROUND It has been hypothesized that glutamatergic transmission may be altered in Tourette syndrome. In this study, we explored the efficacy of a glutamate agonist (D-serine) and antagonist (riluzole) as tic-suppressing agents in children with Tourette syndrome. METHODS We performed a parallel three-arm, 8-week, double-blind, randomized placebo-controlled treatment study in children with Tourette syndrome. Each child received 6 weeks of treatment with D-serine (maximum dose 30 mg/kg/day), riluzole (maximum dose 200 mg/day), or placebo, followed by a 2-week taper. The primary outcome measure was effective tic suppression as determined by the differences in the Yale Global Tic Severity Scale score; specifically, the total tic score and the combined score (total tic score + global impairment) between treatment arms after 6 weeks of treatment. Mann-Whitney U tests were performed to analyze differences between each group and the placebo group. RESULTS Twenty-four patients (males = 21, ages 9-18) enrolled in the study; one patient dropped out before completion. Combined Yale Global Tic Severity Scale score and total tic scores improved in all groups. The 6-week mean percent improvement of the riluzole (n = 10), D-serine (n = 9), and placebo (n = 5) groups in the combined Yale Global Tic Severity Scale score were 43.7, 39.5, and 30.2 and for total tic scores were 38.0, 25.0, and 34.0, respectively. There were no significant differences in Yale Global Tic Severity Scale score or total tic score, respectively, between the riluzole and placebo (P = 0.35, 0.85) or D-serine and placebo (P = 0.50, 0.69) groups. CONCLUSION Tics diminished by comparable percentages in the riluzole, D-serine, and placebo groups. These preliminary data suggest that D-serine and riluzole are not effective in tic suppression.

Abstract
BACKGROUND Tic disorders, such as the Gilles de la Tourette syndrome and persistent tic disorder, are neurodevelopmental movement disorders involving impaired motor control. Hence, patients show repetitive unwanted muscular contractions in one or more parts of the body. A cognitive-behavioral therapy, with a particular emphasis on the psychophysiology of tic expression and sensorimotor activation, can reduce the frequency and intensity of tics. However, its impact on motor activation and inhibition is not fully understood. METHODS To study the effects of a cognitive-behavioral therapy on electrocortical activation, we recorded the event-related potentials (ERP) and lateralized readiness potentials (LRP), before and after treatment, of 20 patients with tic disorders and 20 healthy control participants (matched on age, sex and intelligence), during a stimulus-response compatibility inhibition task. The cognitive-behavioral therapy included informational, awareness training, relaxation, muscle discrimination, cognitive restructuration and relapse prevention strategies. RESULTS Our results revealed that prior to treatment; tic patients had delayed stimulus-locked LRP onset latency, larger response-locked LRP peak amplitude, and a frontal overactivation during stimulus inhibition processing. Both stimulus-locked LRP onset latency and response-locked LRP peak amplitude normalized after the cognitive behavioral therapy completion. However, the frontal overactivation related to inhibition remained unchanged following therapy. CONCLUSIONS Our results showed that P300 and reaction times are sensitive to stimulus-response compatibility, but are not related to tic symptoms. Secondly, overactivity of the frontal LPC and impulsivity in TD patients were not affected by treatment. Finally, CBT had normalizing effects on the activation of the pre-motor and motor cortex in TD patients. These results imply specific modifications of motor processes following therapy, while inhibition processes remained unchanged. Given that LRPs are partially generated within the sensorimotor and supplementary motor area, the reported reduction in tic frequency and improvements of LRPs components suggest that CBT induced a physiological change in patients' motor area.

Abstract
UNLABELLED This report examined the most frequently reported bothersome tics among individuals with chronic tic disorders and evaluated the improvement and remission of tics and their associated characteristics. Youths and adults (N = 240) were randomly assigned to receive the comprehensive behavioral intervention for tics (CBIT) or psychoeducation and supportive therapy (PST). At baseline, motor tics and tics with an urge were rated as more bothersome relative to vocal tics and tics without premonitory urges. The five most common bothersome tics included eye blinking, head jerks, sniffing, throat clearing, and other complex motor tics. While CBIT outperformed PST across tic type and urge presence, tics preceded by premonitory urges at baseline had higher severity at posttreatment across treatment condition. Six individual tic types had lower severity at posttreatment following CBIT relative to PST. Baseline urge presence was associated with tic remission for CBIT but not PST. Specific bothersome tics were more likely to remit with CBIT relative to PST. Findings suggest that individual tics respond and remit differently to CBIT relative to PST, with implications highlighting the negative reinforcement hypothesis in tic symptom maintenance.

Abstract
BACKGROUND Tourette's disorder (TD) is a chronic childhood-onset disorder characterized by the presence of multiple motor and vocal tics. Despite strong evidence that the pathophysiology of TD involves structural and functional disturbances of the basal ganglia and cortical frontal areas, in vivo imaging studies have produced conflicting results. Recent developments in near-infrared spectroscopy (NIRS) technology have enabled noninvasive assessment of brain function in people with psychiatric disorders. METHODS We asked 10 individuals with pediatric TD and 10 healthy controls who were age- and sex- matched to perform the Stroop color-word task during NIRS. We used prefrontal probes and a 24-channel NIRS machine to measure the relative concentrations of oxyhemoglobin (oxy-Hb) every 0.1 s during the task. RESULTS We found that oxy-Hb changes in the prefrontal cortex were significantly smaller in the TD group compared with the control group, especially in the left dorsolateral prefrontal cortex. CONCLUSIONS Our data suggest that individuals with pediatric TD have a reduced prefrontal hemodynamic response as measured by NIRS.

Abstract
Pharmacological and behavioral interventions have focused on reducing tic severity to alleviate tic-related impairment for youth with chronic tic disorders (CTDs), with no existing intervention focused on the adverse psychosocial consequences of tics. This study examined the preliminary efficacy of a modularized cognitive behavioral intervention ("Living with Tics", LWT) in reducing tic-related impairment and improving quality of life relative to a waitlist control of equal duration. Twenty-four youth (ages 7-17 years) with Tourette Disorder or Chronic Motor Tic Disorder and psychosocial impairment participated. A treatment-blind evaluator conducted all pre- and post-treatment clinician-rated measures. Youth were randomly assigned to receive the LWT intervention (n=12) or a 10-week waitlist (n=12). The LWT intervention consisted of up to 10 weekly sessions targeted at reducing tic-related impairment and developing skills to manage psychosocial consequences of tics. Youth in the LWT condition experienced significantly reduced clinician-rated tic-impairment, and improved child-rated quality of life. Ten youth (83%) in the LWT group were classified as treatment responders compared to four youth in the waitlist condition (33%). Treatment gains were maintained at one-month follow-up. Findings provide preliminary data that the LWT intervention reduces tic-related impairment and improves quality of life for youth with CTDs.

Abstract
Tourette syndrome (TS) is a neuropsychiatric disorder characterized by recurrent motor and vocal tics, often accompanied by obsessive-compulsive disorder and/or attention-deficit/hyperactivity disorder. While the evidence for a genetic contribution is strong, its exact nature has yet to be clarified fully. There is now mounting evidence that the genetic risks for TS include both common and rare variants and may involve complex multigenic inheritance or, in rare cases, a single major gene. Based on recent progress in many other common disorders with apparently similar genetic architectures, it is clear that large patient cohorts and open-access repositories will be essential to further advance the field. To that end, the large multicenter Tourette International Collaborative Genetics (TIC Genetics) study was established. The goal of the TIC Genetics study is to undertake a comprehensive gene discovery effort, focusing both on familial genetic variants with large effects within multiply affected pedigrees and on de novo mutations ascertained through the analysis of apparently simplex parent-child trios with non-familial tics. The clinical data and biomaterials (DNA, transformed cell lines, RNA) are part of a sharing repository located within the National Institute for Mental Health Center for Collaborative Genomics Research on Mental Disorders, USA, and will be made available to the broad scientific community. This resource will ultimately facilitate better understanding of the pathophysiology of TS and related disorders and the development of novel therapies. Here, we describe the objectives and methods of the TIC Genetics study as a reference for future studies from our group and to facilitate collaboration between genetics consortia in the field of TS.

Abstract
Comprehensive Behavioral Intervention for Tics (CBIT) is an efficacious treatment for children with Chronic Tic Disorders (CTDs). Nevertheless, many families of children with CTDs are unable to access CBIT due to a lack of adequately trained treatment providers, time commitment, and travel distance. This study established the interrater reliability between in-person and VoIP administrations of the Yale Global Tic Severity Scale (YGTSS), and examined the preliminary efficacy, feasibility, and acceptability of Voice over Internet Protocol (VoIP)-delivered CBIT for reducing tics in children with CTDs in an open case series. Across in-person and VoIP administrations of the YGTSS, results showed mean agreement of 91%, 96%, and 95% for motor, phonic, and total tic severity subscales. In the pilot feasibility study, four children received 8-weekly sessions of CBIT via VoIP and were assessed at pre- and post-treatment by an independent evaluator. Results showed a 29.44% decrease in clinician-rated tic severity from pre to post-assessment on the YGTSS. Two of the four patients were considered treatment responders at post treatment, using Clinical Global Impressions-Improvement ratings. Therapeutic alliance, parent and child treatment satisfaction and videoconferencing satisfaction ratings were high. CBIT was considered feasible to implement via VoIP, although further testing is recommended.

Abstract
Recent randomized clinical trials have established the efficacy of Comprehensive Behavioral Intervention for Tics (CBIT) in treating children and adults with Tourette syndrome and persistent tic disorders. However, the standard CBIT protocol uses a weekly outpatient treatment format (i.e., 8 sessions over 10 wk), which may be inconvenient or impractical for some patients, particularly patients, who are required to travel long distances in order to receive care. In contrast, an intensive outpatient program may increase accessibility to evidence-based behavioral treatments for Tourette syndrome and other persistent tic disorders by eliminating the necessity of repeated travel. This case series evaluated the use of an intensive outpatient program CBIT (IOP CBIT) for the treatment of 2 preadolescent males (ages 10 and 14 years) with Tourette syndrome. The IOP CBIT treatment protocol included several hours of daily treatment over a 4-d period. Both children evidenced notable reductions in their tics and maintained treatment gains at follow-up. Moreover, both patients and their parents expressed treatment satisfaction with the IOP CBIT format. This case series addresses an important research gap in the behavioral treatment of tic disorders literature. The patients’ treatment outcomes indicate that IOP CBIT is a promising treatment that warrants more systematic investigation.

Abstract
Georges Gilles de la Tourette, in describing the syndrome that now bears his name, observed that the condition aggregated within families. Over the last three decades, numerous studies have confirmed this observation, and demonstrated that familial clustering is due in part to genetic factors. Recent studies are beginning to provide clues about the underlying genetic mechanisms important for the manifestation of some cases of Tourette Disorder (TD). Evidence has come from different study designs, such as nuclear families, twins, multigenerational families, and case-control samples, together examining the broad spectrum of genetic variation including cytogenetic abnormalities, copy number variants, genome-wide association of common variants, and sequencing studies targeting rare and/or de novo variation. Each of these classes of genetic variation holds promise for identifying the causative genes and biological pathways contributing to this paradigmatic neuropsychiatric disorder.

We aimed to examine the effectiveness of combined neurofeedback therapy and imagery training in adolescent patients with refractory Tourette syndrome. Two patients, aged respectively 14 and 16 years, had been treated with haloperidol and tiapride; however, this medication was ineffective and accompanied by intolerable side effects. In this study, the patients completed 80 sessions of neurofeedback treatment followed by imagery training. The patients were assessed with behavior rating scales both before and after the treatment as well as during follow-up examinations to evaluate the effect of the combined therapy. Patients showed significant improvement in motor tic and vocal tic symptoms, exemplified by a reduction in the frequency and intensity of tics, indicating that neurofeedback, together with imagery training, has a positive therapeutic effect on adolescent patients with medication-refractory Tourette syndrome.

Abstract
OBJECTIVE The Diagnostic Interview Schedule for Children IV (DISC) has been used extensively in research and screening. Despite wide use, little information exists on the validity of the DISC for diagnosing tic disorders. METHODS Participants were 181 youth with expert clinician-diagnosed Tourette syndrome (TS). RESULTS Using expert clinician-diagnosed TS as the gold standard, the sensitivity of the DISC-Y (youth, 0.27) and DISC-P (parent, 0.44) was poor. The DISC-Y identified 29.7% of youth with diagnosed TS whereas the DISC-P identified 47.4% of cases. Only 54% of cases of TS were detected by either the DISC-Y or -P. Diagnostic agreement between the DISC and expert clinician diagnosis was poor. The DISC-Y/P results did not differ as a function of tic severity. CONCLUSIONS Despite utility for assessing child psychiatric disorders, the sensitivity of the DISC for detecting TS appears poor. This study suggests that DISC has low agreement with expert clinician diagnosis of TS. Findings highlight the need for modification of the DISC and/or the identification and development of more sensitive measures for TS screening.

Abstract
Individual randomized controlled trials (RCTs) of habit reversal training and a Comprehensive Behavioral Intervention for Tics (collectively referred to as behavior therapy, BT) have demonstrated efficacy in reducing tic severity for individuals with Tourette Syndrome and Chronic Tic Disorders (collectively referred to as TS), with no examination of treatment moderators. The present meta-analysis synthesized the treatment effect sizes (ES) of BT relative to comparison conditions, and examined moderators of treatment. A comprehensive literature search identified eight RCTs that met inclusion criteria, and produced a total sample of 438 participants. A random effects meta-analysis found a medium to large ES for BT relative to comparison conditions. Participant mean age, average number of therapy sessions, and the percentage of participants with co-occurring attention deficit hyperactivity disorder (ADHD) were found to moderate treatment effects. Participants receiving BT were more likely to exhibit a treatment response compared to control interventions, and identified a number needed to treat (NNT) of three. Sensitivity analyses failed to identify publication bias. Overall, BT trials yield medium to large effects for TS that are comparable to treatment effects identified by meta-analyses of antipsychotic medication RCTs. Larger treatment effects may be observed among BT trials with older participants, more therapeutic contact, and less co-occurring ADHD.

Abstract
BACKGROUND/PURPOSE The purpose of this study was to evaluate the effectiveness and tolerability of aripiprazole in short-term treatment of children and adolescents with tic disorder (TD). METHODS This was a 14-week, prospective, open-label flexible dose trial of aripiprazole. We enrolled patients with TD aged between 4 years and 18 years. They received aripiprazole (dose: 2.5 mg/day) initially, which was then adjusted according to clinical response. The severity was assessed by the Yale Global Tic Severity Score (YGTSS) at 0, 2, 6, 10, and 14 weeks. The linear mixed models were used for evaluation of the YGTSSs at each follow-up, which were compared with baseline scores. RESULTS Eighty-one patients were enrolled in this study. Nine patients withdrew from the study with complaints of adverse side effects. Of the remaining 72 patients, 15 patients discontinued medications prematurely due to being free of symptoms for over 2 weeks. Two patients discontinued medications due to no significant improvement. The mean scores had significantly decreased since the 2nd week (p < 0.01). The mean reduction was 51.0% in the motor tic scores, 67.1% in the vocal tic scores, and 70.0% in the total YGTSSs. The common adverse effects were sedation (32.1%) and increased appetite (22.2%). A slight increase in average body weight was noted, from 32.7 to 33.7 kg (+1.0 kg, p < 0.05). CONCLUSION Aripiprazole is effective for short-term treatment of TD, especially vocal tics, in children and adolescents with mild adverse effects. However, further double-blind trials against placebo or other medications are needed to verify the efficacy of aripiprazole in the pharmacotherapy of TD.

Abstract
Tourette's syndrome (TS) consists of chronic motor and phonic tics and characteristically begins in childhood. The tics can be disabling and commonly associated behavioral comorbities such as attention deficit hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD), can also cause problems in daily functioning. The underlying etiology and neurobiology of TS remain unknown although genetic factors appear to be important, cortical control of basal ganglia motor function appears to be disturbed and neurochemical abnormalities, particularly involving dopamine neurotransmission, are likely present. The treatment of TS involves appropriate education and support. Tics can be treated with habit reversal cognitive behavioral therapy, medications (most commonly alpha agonists and antipsychotics), local intramuscular injections of botulinum toxin and some severe, refractory cases have responded to deep brain stimulation surgery (DBS). It is important to appropriately diagnose and treat comorbid behavioral disorders that are disrupting function. OCD can be treated with cognitive behavioral therapy, selective serotonin reuptake inhibitors, and atypical antipsychotics. DBS has become a treatment option for patients with disabling OCD despite other therapies. ADHD is treated with appropriate classroom accommodations, behavioral therapy, alpha agonists, atomoxetine or methylphenidate-containing stimulant drugs.

Abstract
OBJECTIVE A subgroup of patients with Tourette's disorder (TD) has symptoms refractory to haloperidol, a standard therapeutic drug for TD. METHODS We report on three cases of pediatric and adolescent patients who were treated with paliperidone extended release. RESULTS In two cases, TD symptoms were remarkably improved by switching from haloperidol to paliperidone extended release, and in another case, paliperidone extended release showed significant efficacy in treating TD symptoms as the first-line drug. In all cases, no significant adverse side effects were detected. CONCLUSION Paliperidone extended release may be a strong candidate for the treatment of pediatric and adolescent patients with TD.

Abstract
Cluster analytic methods have examined the symptom presentation of chronic tic disorders (CTDs), with limited agreement across studies. The present study investigated patterns, clinical correlates, and treatment outcome of tic symptoms. 239 youth and adults with CTDs completed a battery of assessments at baseline to determine diagnoses, tic severity, and clinical characteristics. Participants were randomly assigned to receive either a comprehensive behavioral intervention for tics (CBIT) or psychoeducation and supportive therapy (PST). A cluster analysis was conducted on the baseline Yale Global Tic Severity Scale (YGTSS) symptom checklist to identify the constellations of tic symptoms. Four tic clusters were identified: Impulse Control and Complex Phonic Tics; Complex Motor Tics; Simple Head Motor/Vocal Tics; and Primarily Simple Motor Tics. Frequencies of tic symptoms showed few differences across youth and adults. Tic clusters had small associations with clinical characteristics and showed no associations to the presence of coexisting psychiatric conditions. Cluster membership scores did not predict treatment response to CBIT or tic severity reductions. Tic symptoms distinctly cluster with little difference across youth and adults, or coexisting conditions. This study, which is the first to examine tic clusters and response to treatment, suggested that tic symptom profiles respond equally well to CBIT.

Abstract
To document the impact of Tourette syndrome on the health care needs of children and access to health care among youth with Tourette syndrome, parent-reported data from the 2007-2008 National Survey of Children's Health were analyzed. Children with Tourette syndrome had more co-occurring mental disorders than children with asthma or children without Tourette syndrome or asthma and had health care needs that were equal to or greater than children with asthma (no Tourette syndrome) or children with neither asthma nor Tourette syndrome. Health care needs were greatest among children with Tourette syndrome and co-occurring mental disorders, and these children were least likely to receive effective care coordination. Addressing co-occurring conditions may improve the health and well-being of children with Tourette syndrome. Strategies such as integration of behavioral health and primary care may be needed to improve care coordination.

Abstract
Restricted interests and repetitive behaviors vary widely in type, frequency, and intensity among children and adolescents with autism spectrum disorder. They can be stigmatizing and interfere with more constructive activities. Accordingly, restricted interests and repetitive behaviors may be a target of intervention. Several standardized instruments have been developed to assess restricted interests and repetitive behaviors in the autism spectrum disorder population, but the rigor of psychometric assessment is variable. This article evaluated the readiness of available measures for use as outcome measures in clinical trials. The Autism Speaks Foundation assembled a panel of experts to examine available instruments used to measure restricted interests and repetitive behaviors in youth with autism spectrum disorder. The panel held monthly conference calls and two face-to-face meetings over 14 months to develop and apply evaluative criteria for available instruments. Twenty-four instruments were evaluated and five were considered “appropriate with conditions” for use as outcome measures in clinical trials. Ideally, primary outcome measures should be relevant to the clinical target, be reliable and valid, and cover the symptom domain without being burdensome to subjects. The goal of the report was to promote consensus across funding agencies, pharmaceutical companies, and clinical investigators about advantages and disadvantages of existing outcome measures.

Abstract
BACKGROUND Research suggests Tourette syndrome (TS) can have a negative impact on quality of life. To date, little research has examined the perspectives of young people with this condition in depth. METHODS Six 14- to 16-year-olds with TS took part in semi-structured interviews to explore the perceived impact of this condition on self and on relationships with others. The transcripts were analysed using interpretative phenomenological analysis. RESULTS The young people felt that TS was a constant presence in their lives, but one they have learnt to cope with well. Most had developed supportive friendships but encountered problems when interacting with the wider peer network. Specific concerns around meeting new people and future employment were voiced. CONCLUSIONS The adolescents described specific ways in which TS affects quality of life and social interactions, and the effort it can take to cope effectively with this condition.

Abstract
In the present manuscript we review a substantial body of literature describing several pre-clinical animal models designed and developed with the purpose of investigating the biological determinants of Tourette syndrome (TS). In order to map the animal models onto the theoretical background upon which they have been devised, we first define phenomenological and etiological aspects of TS and then match this information to the available pre-clinical models. Thus, we first describe the characteristic symptoms exhibited by TS patients and then a series of hypotheses attempting to identify the multifactorial causes of TS. With respect to the former, we detail the phenomenology of abnormal repetitive behaviors (tics and stereotypies), obsessive-compulsive behaviors and aberrant sensory-motor gating. With respect to the latter, we describe both potential candidate vulnerability genes and environmental factors (difficult pregnancies, psychosocial stressors and infections). We then discuss how this evidence has been translated in pre-clinical research with respect to both dependent (symptoms) and independent (etiological factors) variables. Thus, while, on the one hand, we detail the methodologies adopted to measure abnormal repetitive and obsessive-compulsive behaviors, and sensory-motor gating, on the other hand, we describe genetic engineering studies and environmental modulations aimed at reproducing the proposed biological determinants in laboratory rodents. A special emphasis is placed upon "programming" events, occurring during critical stages of early development and exerting organizational delayed consequences. In the final section, we outline a heuristic model with the purpose of integrating clinical and pre-clinical evidence in the study of TS.

Abstract
Tourette syndrome (TS) is a chronic neuropsychiatric disorder characterised by multiple motor and vocal tics, plus associated behavioural symptoms. Tics are defined as sudden, rapid, repetitive non-rhythmic movements (motor tics) or vocalisations (vocal tics). Tics are distressing symptoms and can lead to considerable disruption to social functioning and quality of life. Converging evidence from different lines of research suggests that the pathophysiology of TS involves altered dopaminergic transmission in the cortico-striatal-thalamo-cortical circuits, along with other neurotransmitter systems. Pharmacotherapy is currently the treatment of choice in patients with moderate-to-severe tics, particularly when associated with deterioration in social, occupational or academic performance. This review will focus on the recent evidence base supporting the use of different medication classes for the treatment of tics in TS. The recent publication of the European and Canadian guidelines on the management of TS are based on experts' consensus and highlight the need for randomised controlled trials, especially with regards to newly developed pharmacological agents.

Abstract
Tourettte syndrome (TS) is a common, childhood onset neuropsychiatric disorder consisting of multiple motor and one or more vocal tics which persist for more than 1 year. Comorbid psychiatric diagnoses are frequent in this patient population, including attention-deficit/hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD). Tics can be simple or complex, and have a tendency to change over time. Tics are preceded by a premonitory sensation, wax and wane in frequency, and are often exacerbated by stress or excitement. Tic severity usually peaks in childhood, and improves in early adulthood. TS is a highly heritable disorder with a polygenic inheritance. The fundamental pathophysiology of TS is not known, although existing evidence suggests that it involves dysfunction of the basal ganglia and frontal cortical circuits, as well as dopaminergic neurotransmission. Treatment of TS involves consideration of symptom severity and comorbidity. In general, comorbid ADHD and OCD lead to greater disability in these patients, and therefore are the initial treatment priority. As treatment for tics does not alter the natural history of the disorder, it is only recommended if the tics are causing disability. Effective treatments to suppress tics include α-adrenergic agonists and antipsychotic medications.

Abstract
In individuals with Tourette's syndrome, the therapeutic efficacy of haloperidol can be augmented by nicotine. In laboratory rats, the dopamine antagonist haloperidol produces catalepsy and nicotine can potentiate it, although this effect is variable and not always observed. Our aim was to understand this variability. In rats, the locomotor response to a novel environment predicts the magnitude of the locomotor response to nicotine. Since the psychostimulant effect of nicotine might counter catalepsy, we hypothesized that rats with a high locomotor response to novelty would show reduced vulnerability to nicotine potentiation of haloperidol catalepsy. First, we administered haloperidol (0, 0.1 or 0.3mg/kg, ip) and found stronger catalepsy in rats with low reactivity to novelty. Second, we administered haloperidol (0.3mg/kg) or haloperidol plus nicotine (0.1mg/kg, ip) and found that nicotine indeed potentiated haloperidol catalepsy but only in rats with low reactivity to novelty. Nicotine did not induce catalepsy on its own. Thus, previously reported inconsistencies in the catalepsy potentiating effect of nicotine may have been due to differential vulnerability to its stimulant actions. As previously observed, the potentiation of haloperidol catalepsy was greatest 4h after injection. Given the short half-life of nicotine, the mechanism(s) underlying the delayed expression of its pro-cataleptic capacity remains obscure.

Abstract
Forty years of research and clinical practice have proved dopamine (DA) receptor antagonists to be effective agents in the treatment of Tourette's syndrome (TS), allowing a significant tic reduction of about 70%. Their main effect seems to be mediated by the blockade of the striatal DA-D2 receptors. Various typical and atypical agents are available and there is still discord between experts about which of them should be considered as first choice. In addition, there are suggestions to use DA receptor agonists such as pergolide or non-DA-modulating agents. The present chapter is focusing on the clinical pharmacology of DA-modulating agents in the treatment of TS. The introduction outlines their clinical relevance and touches on the hypotheses of the role of DA in the pathophysiology of TS. Subsequently, general information about the mechanisms of action and adverse effects are provided. The central part of the chapter forms a systematic review of all DA-modulating agents used in the treatment of TS, including an overview of studies on their effectiveness, and a critical discussion of their specific adverse effects. The present chapter closes with a summary of the body of evidence and a description of the resulting recommendations for the pharmacological treatment of TS.

Abstract
Tourette syndrome (TS) is a neurodevelopmental disorder characterized by multiple motor/phonic tics and a wide spectrum of behavioral problems (e.g., complex tic-like symptoms, attention deficit hyperactivity disorder, and obsessive-compulsive disorder). TS can be a challenging condition even for the specialists, because of the complexity of the clinical picture and the potential adverse effects of the most commonly prescribed medications. Expert opinions and consensus guidelines on the assessment and treatment of tic disorders have recently been published in Europe and Canada. All pharmacological treatment options are mere symptomatic treatments that alleviate, but do not cure, the tics. We still lack evidence of their effects on the natural long-term course and on the prognosis of TS and how these treatments may influence the natural course of brain development. The most commonly prescribed drugs are dopamine antagonists, such as typical (e.g., haloperidol, pimozide) and atypical neuroleptics (e.g., risperidone, aripiprazole), and α-2-adrenoreceptor agonists (e.g., clonidine). However, several studies have investigated the efficacy and tolerability of alternative pharmacological agents that may be efficacious, including the newest atypical antipsychotic agents (e.g., paliperidone, sertindole), tetrabenazine, drugs that modulate acetylcholine (e.g., nicotine) and GABA (e.g., baclofen, levetiracetam), tetrahydrocannabinol, botulinum toxin injections, anticonvulsant drugs (e.g., topiramate, carbamazepine), naloxone, lithium, norepinephrine, steroid 5α reductase, and other neuroactive agents (buspirone, metoclopramide, phytostigmine, and spiradoline mesylate). As regards nonpharmacological interventions, some of the more recent treatments that have been studied include electroconvulsive therapy and repetitive transcranial magnetic stimulation. This review focuses primarily on the efficacy and safety of these emerging treatment strategies in TS.

Abstract
OBJECTIVES The objective of our paper is to show the partial decrease of therapeutic effect with battery exhaustion in a previously successfully treated patient with refractory Tourette's syndrome (TS). MATERIALS AND METHODS We present a 47-year-old patient diagnosed with TS based on the TS Study Group Criteria and Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. Surgery was considered based on refractoriness to conservative management. Presurgical evaluation included magnetic resonance imaging (MRI), positron emission tomography scan, and neuropsychologic, neurologic, and psychiatric tests utilizing Yale Brown Obsessive Compulsive Scale, Yale Global Tics Severity Scale, Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, Global Assessment of Functioning Scale, and Mini-mental State Examination. Target coordinates were obtained from inversion recovery MRI. Quadripolar deep brain stimulation (DBS) electrodes were implanted bilaterally in the globus pallidus externus (GPe) and connected to the pulse generator in the same procedure. To determine the clinical response to DBS, the scores of the scales obtained preoperatively were compared with those obtained postoperatively. RESULTS No surgical complications were detected and according to the clinical scales the patient experienced a marked improvement of his symptoms, although he never showed obsessive-compulsive disorder components of any type. The battery was exhausted after two years with the subsequent significant partial loss of therapeutic effect. CONCLUSIONS GPe seems to be a highly promising target of DBS for the treatment of medically refractory TS. After battery exhaustion, the patient experienced a marked partial decrease in the therapeutic effect, which confirms the beneficial action of this method.

Abstract
Pharmacological treatment is usually indicated in moderate to severe tics in psychosocial and/or functional impairment. Neuroleptics with D2 antagonistic activity remain the cornerstone of anti-tic therapy. Lack of randomized controlled clinical trials base therapeutic decisions mainly on clinical expertise and common sense. Recently, aripiprazole has emerged as the neuroleptic with the most advantageous efficacy/side effect ratio for treating tics. Yet, in non-responders to aripiprazole, many neuroleptic and non-neuroleptic drugs, including botulinum toxin injections, are available and often successful. Apart from conducting methodologically sound trials (which includes sufficiently long observation periods), future efforts in the field should test the combination of cognitive-behavioral therapy with drugs or of multi-drug therapy as well as the development of biomarkers (endophenotypes) to monitor and even predict treatment response.

Abstract
BACKGROUND Eighteen patients with severe and refractory Tourette Syndrome underwent bilateral thalamic deep brain stimulation. The surgical procedures and stimulation processes of the cohort were reported in 2008; the 2 year follow-up was reported in 2009. The aim of the research is the assessment of long-term outcome (5-6 years) on tics, obsessional behaviours, anxiety, mood, and on the overall general health of the patients and their general satisfaction. METHOD In this study, all 18 of the original patients will be discussed, pre- and post-DBS, according to our protocol using standardized objective schedules, as well as the clinical impressions of both clinicians and patients. As there were no substantial nor statistical differences on measures of cognitive functioning between pre-DBS and 2 year follow-up, we decided not to continue this aspect of the formal assessment, particularly as there were also no clinical indications. RESULTS At 5-6 year follow-up, there was a significant reduction in tic severity (p < 0.001), and significant improvements in obsessive compulsive behaviours (p = 0.003), anxiety (p < 0.001) and depressive (p < 0.001) symptoms. Patients, in general, required less medication for tics, co-morbid conditions and/or co-existent psychopathologies. The long-term outcome/satisfaction were not unanimous between patients and the medical team. CONCLUSIONS At long-term follow-up, DBS was very successful in terms of a significant improvement in tics and also a significant reduction in the potentially disabling symptoms of obsessionality, anxiety and depression. However, compared with our more positive overall results at 2 years, these later results demonstrate long-term difficulties as follows: non-compliance, long-term complications , and the differences in the opinions between the (a) medical, (b) the surgical teams and (c) the post-DBS patients as to their outcome/satisfaction with the procedures. Our experience highlights the need for controlled studies, for long-term follow up, and the need to improve the selection of patients for DBS.

Abstract
We conducted a meta-analysis of randomized, placebo-controlled trials to determine the efficacy of antipsychotic and alpha-2 agonists in the treatment of chronic tic disorders and examine moderators of treatment effect. Meta-analysis demonstrated a significant benefit of antipsychotics compared to placebo (standardized mean difference (SMD)=0.58 (95% confidence interval (CI): 0.36-0.80). Stratified subgroup analysis found no significant difference in the efficacy of the 4 antipsychotic agents tested (risperidone, pimozide, haloperidol and ziprasidone). Meta-analysis also demonstrated a benefit of alpha-2 agonists compared to placebo (SMD=0.31 (95% confidence interval CI: 0.15-0.48). Stratified subgroup analysis and meta-regression demonstrated a significant moderating effect of co-occurring ADHD. Trials which enrolled subjects with tics and ADHD demonstrated a medium-to-large effect (SMD=0.68 (95%CI: 0.36-1.01) whereas trials that excluded subjects with ADHD demonstrated a small, non-significant benefit (SMD=0.15 (95%CI: -0.06 to 0.36). Our findings demonstrated significant benefit of both antipsychotics and alpha-2 agonists in treating tics but suggest alpha-2 agonists may have minimal benefit in tic patients without ADHD.

Abstract
CONTEXT Tics in Tourette syndrome begin in childhood, peak in early adolescence, and often decrease by early adulthood. However, some adult patients continue to have impairing tics. Medications for tics are often effective but can cause adverse effects. Behavior therapy may offer an alternative but has not been examined in a large-scale controlled trial in adults. OBJECTIVE To test the efficacy of a comprehensive behavioral intervention for tics in adults with Tourette syndrome of at least moderate severity. DESIGN A randomized controlled trial with posttreatment evaluations at 3 and 6 months for positive responders. SETTING Three outpatient research clinics. PATIENTS Patients (N = 122; 78 males; age range, 16-69 years) with Tourette syndrome or chronic tic disorder were recruited between December 27, 2005, and May 21, 2009. INTERVENTIONS Patients received 8 sessions of comprehensive behavioral intervention for tics or 8 sessions of supportive treatment for 10 weeks. Patients with a positive response were given 3 monthly booster sessions. MAIN OUTCOME MEASURES Total tic score on the Yale Global Tic Severity Scale and the Clinical Global Impression-Improvement scale rated by a clinician masked to treatment assignment. RESULTS Behavior therapy was associated with a significantly greater mean (SD) decrease on the Yale Global Tic Severity Scale (24.0 [6.47] to 17.8 [7.32]) from baseline to end point compared with the control treatment (21.8 [6.59] to 19.3 [7.40]) (P < .001; effect size = 0.57). Twenty-four of 63 patients (38.1%) were rated as much improved or very much improved on the Clinical Global Impression-Improvement scale compared with 4 of 63 (6.4%) in the control group (P < .001). Attrition was 13.9%, with no difference across groups. Patients receiving behavior therapy who were available for assessment at 6 months after treatment showed continued benefit. CONCLUSION Comprehensive behavior therapy is a safe and effective intervention for adults with Tourette syndrome. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT00231985.

TOPIC Habit reversal training (HRT) is emerging as an efficacious behavioral intervention for Tourette syndrome in children and adults. PURPOSE The purpose of this article is to review the recent literature investigating the efficacy of HRT for treating children with chronic tic disorders. SOURCES This review examines single-subject design studies and randomized, controlled trials of HRT conducted in children with chronic tic disorders since 2000. CONCLUSIONS Intervention built on HRT appears to be effective for decreasing tic severity in children and adolescents. Results from a recent multisite trial suggest that incorporation of functional analysis may enhance the effectiveness of traditional HRT.

Abstract
PURPOSE Based on the success of deep brain stimulation (DBS) in the treatment of adult disorders, it is reasonable to assume that the application of DBS in the pediatric population is an emerging area worthy of study. The purpose of this paper is to outline the current movement disorder indications for DBS in the pediatric population, and to describe areas of investigation, including possible medically refractory psychiatric indications. METHODS We performed a structured review of the English language literature from 1990 to 2011 related to studies of DBS in pediatrics using Medline and PubMed search results. RESULTS Twenty-four reports of DBS in the pediatric population were found. Based on published data on the use of DBS for pediatric indications, there is a spectrum of clinical evidence for the use of DBS to treat different disorders. Dystonia, a disease associated with a low rate of remission and significant disability, is routinely treated with DBS and is currently the most promising pediatric application of DBS. We caution the application of DBS to conditions associated with a high remission rate later in adulthood, like obsessive-compulsive disorder and Tourette's syndrome. Moreover, epilepsy and obesity are currently being investigated as indications for DBS in the adult population; however, both are associated with significant morbidity in pediatrics. CONCLUSION While currently dystonia is the most promising application of DBS in the pediatric population, multiple conditions currently being investigated in adults also afflict children and adolescents, and thus warrant further research.

Abstract
This review summarizes evidence of dysregulated reward circuitry function in a range of neurodevelopmental and psychiatric disorders and genetic syndromes. First, the contribution of identifying a core mechanistic process across disparate disorders to disease classification is discussed, followed by a review of the neurobiology of reward circuitry. We next consider preclinical animal models and clinical evidence of reward-pathway dysfunction in a range of disorders, including psychiatric disorders (i.e., substance-use disorders, affective disorders, eating disorders, and obsessive compulsive disorders), neurodevelopmental disorders (i.e., schizophrenia, attention-deficit/hyperactivity disorder, autism spectrum disorders, Tourette's syndrome, conduct disorder/oppositional defiant disorder), and genetic syndromes (i.e., Fragile X syndrome, Prader-Willi syndrome, Williams syndrome, Angelman syndrome, and Rett syndrome). We also provide brief overviews of effective psychopharmacologic agents that have an effect on the dopamine system in these disorders. This review concludes with methodological considerations for future research designed to more clearly probe reward-circuitry dysfunction, with the ultimate goal of improved intervention strategies.

Abstract
AIMS National differences in licensing laws suggest that the use of medications for the treatment of Tourette syndrome differs between European countries. However, variability in prescribing practices has never been investigated. This study aims to systematically examine European prescribing practices in Tourette syndrome. METHODS All members of the European Society for the Study of Tourette syndrome actively prescribing for paediatric and/or adult Tourette syndrome populations were invited to complete an online questionnaire covering pharmacological treatment of the five main symptom domains of Tourette syndrome: tics, attention-deficit hyperactivity symptoms, obsessive-compulsive symptoms, anxiety and depression. RESULTS Response rates were good, with 44/57 (77%) members returning the questionnaire. Risperidone (n=13), methylphenidate (n=21) and sertraline (n=17) were the most commonly prescribed medications for the treatment of tics, attention-deficit hyperactivity symptoms and obsessive-compulsive symptoms, respectively. However, there was a large variability in both the medication choices and the dosages used for each of these symptom domains. CONCLUSIONS This is the first large-scale survey on prescribing habits for the pharmacological management of Tourette syndrome in Europe. In general, dopamine blockers were widely used for tics, selective serotonin reuptake inhibitors for depression, obsessive-compulsive symptoms and anxiety, and stimulants for attention-deficit hyperactivity symptoms, but there was high variation within these choices. Future studies need to target specific patient groups.

Pharmacological treatment of tic disorders and Tourette Syndrome. Neuropharmacology 2012; 68:143-9.

Abstract
The present review gives an overview of current pharmacological treatment options of tic disorders and Tourette Syndrome (TS). After a short summary on phenomenology, clinical course and comorbid conditions we review indications for pharmacological treatment in detail. Unfortunately, standardized and large enough drug trials in TS patients fulfilling evidence based medicine standards are still scarce. Treatment decisions are often guided by individual needs and personal experience of treating clinicians. The present recommendations for pharmacological tic treatment are therefore based on both scientific evidence and expert opinion. As first-line treatment of tics risperidone (best evidence level for atypical antipsychotics) or tiapride (largest clinical experience in Europe and low rate of adverse reactions) are recommended. Aripiprazole (still limited but promising data with low risk for adverse reactions) and pimozide (best evidence of the typical antipsychotics) are agents of second choice. In TS patients with comorbid attention deficit hyperactivity disorder (ADHD) atomoxetine, stimulants or clonidine should be considered, or, if tics are severe, a combination of stimulants and risperidone. When mild to moderate tics are associated with obsessive-compulsive symptoms, depression or anxiety sulpiride monotherapy can be helpful. In more severe cases the combination of risperidone and a selective serotonin reuptake inhibitor should be given. In summary, further studies, particularly randomized, double-blind, placebo-controlled trials including larger and/or more homogenous patient groups over longer periods are urgently needed to enhance the scientific basis for drug treatment in tic disorders. This article is part of the Special Issue entitled 'Neurodevelopmental Disorders'.
