Abstract
BACKGROUND The comorbidities of either epilepsy or Tourette syndrome (TS) are heterogeneous. However, the co-occurrence of epilepsy and TS conditions is rarely encountered, let alone effective treatments that address both neurologic disorders at the same time. METHODS We report a 24-year-old female patient who was diagnosed with TLE and TS. She presented for seizure control. After evaluation with stereo-electroencephalography and electrocorticography monitoring, the patient underwent a resective surgery treatment and was followed for 9 months. RESULTS At the last follow-up, the patient remained seizure free and unexpectedly showed great improvement in TS symptoms and its psychiatric comorbidities. CONCLUSION This anecdotal case highlights the close association between TLE and TS and we suggest that epilepsy and TS share some common pathophysiologic mechanisms.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE As a traditional Chinese medicine formula, Jingxin Zhidong Formula (JXZDF) based on ancient amber powder has been prescribed to alleviate tic disorders (TD) according to our clinical practice for many years. However, the underlying molecular mechanisms remain largely unknown. AIM OF STUDY To explore the potential mechanism of JXZDF in the treatment of TD by using network pharmacology and experimental validation. MATERIALS AND METHODS The chemical components of JXZDF were detected and the potential pathway enrichment analyses were conducted based on network pharmacology. Finally, we performed cell viability assays and Western blotting on LPS-induced BV-2 cells, and subsequently performed behavioral tests and Western blotting in SD rats model for TD to explore the mechanism of JXZDF on TD. RESULTS By LC-ESI-MS/MS system and searching the databases, we identified 5 key compounds and 29 hub targets of JXZDF on TD. KEGG enrichment analysis showed that PI3K/AKT signaling pathway may be the key pathway for JXZDF on TD. The vitro experimental results proved that JXZDF can inhibit the phosphorylation of PI3K and AKT proteins on LPS-induced BV-2 cells. The animal experimental results indicated that JXZDF can effectively alleviate the stereotypic behavior and hyperactivity of the TD rats, and downregulated PI3K/AKT pathway to inhibit microglia activation in the hippocampus tissue. CONCLUSION This study indicated that JXZDF can change microglial activation and expression of proinflammatory mediators through the inactivation of PI3K/AKT signaling pathway, which may be one of the mechanisms of JXZDF in treating TD.

Abstract
BACKGROUND Sleep problems are common in children with Tourette Syndrome (TS). However, research regarding their demographic and clinical profile is limited. METHODS We examined characteristics of 114 children aged five to 17 years with a lifetime diagnosis of TS and compared children with sleep disorder (n = 32) and without sleep disorder (n = 82). Parent report from the 2014 National Survey of the Diagnosis and Treatment of ADHD and Tourette Syndrome provided demographics and clinical information, other diagnosed disorders, medication use, TS severity, and impairment. RESULTS More children with TS with sleep disorder were from households with lower parental education (P < 0.01) and poverty (P = 0.04); had other diagnoses (P = 0.03), including obsessive-compulsive disorder (P < 0.01), oppositional defiant disorder or conduct disorder (P < 0.01), attention-deficit/hyperactivity disorder (ADHD) (P = 0.02), and autism (P = 0.03); and had ever used TS medication (P = 0.01) than children with TS without sleep disorder. More children with TS with sleep disorder had severe TS symptoms (P <0.01), tic-related impairment (P<0.01), and severe ADHD symptoms (P < 0.01) compared with children with TS without sleep disorder. CONCLUSIONS Findings suggest greater parent-reported impact and tic-related interference in children with TS with sleep disorder compared with TS without sleep disorder. Results underscore the importance of monitoring and intervention for TS exacerbations, other diagnosed disorders, and medication use, and consideration of socioeconomic context in sleep disorder management and prevention in children with TS.

Abstract
Chronic tic disorders, such as Tourette syndrome, are characterized by motor and vocal tics. Tics present a considerable burden for some patients, and therefore, effective treatment is important. One evidence-based treatment option is a behavioral therapy called exposure and response prevention (ERP). Despite its effectiveness, access to ERP remains limited due to a lack of treatment sites. Web-based videoconferences can connect patients at home with a therapist located in the hospital, allowing for treatment delivery over a wide geographic area. The primary aim of this study was to compare the development of tics during and 1 year after ERP delivery, respectively, via web-based videoconferences and traditional face-to-face methods in a naturalistic setting. In total, 116 patients treated using either the face-to-face method (n = 72) or web-based videoconferences (n = 44) were included. The primary outcome measure was tic severity. In both training modalities, tic severity decreased during ERP and the effect lasted in the follow-up period. No statistically significant differences in tic severity between the training modalities were found at baseline, last training session, or at follow-up. Our results suggest that ERP delivered via web-based videoconferences is a good alternative to the traditional face-to-face method.

Abstract
Tourette syndrome and chronic tic disorders are characterized by the presence of tics. Different behavioral therapies have shown to be efficacious for treating tics in children and adolescents, but Exposure and Response Prevention (ERP) is a less researched method. However, ERP is a method often used in the clinical setting. Therefore, the present study evaluated the severity of tics over time from beginning of ERP to follow-up approximately 1 year after last training session.In total, 116 patients treated with ERP face to face or ERP via web-based videoconferencing were included. The primary outcome measure was tic severity measured with the Danish version of the Yale Global Tic Severity Scale.The results showed that tic severity decreased during ERP and lasted in the follow-up period, with a statistically higher decrease in the group with patients who completed ERP as planned and the group that stopped earlier than planned because of reduction in tics, compared with those who dropped out due to lack of motivation (p < 0.001).The study concludes that ERP seems to have an immediate and a long-term effect on severity of tics, especially in those who complete the program or those who discontinue earlier due to good results.

Abstract
The precise cortical and subcortical mechanisms of Tourette syndrome (TS) are still not fully understood. In the present retrospective analysis, adolescent and adult medication-naïve patients showed increased DA transporter (DAT) binding in nucleus caudate (CAUD), putamen (PUT) and/or whole neostriatum (NSTR). D2 receptor (R) binding and DA release were not different from controls throughout the nigrostriatal and mesolimbocortical system. When patients were medication-free (either medication-naïve or under withdrawal), DAT was still increased in PUT, but not different from controls in CAUD, NSTR and ventral striatum (VSTR). SERT was unaltered in midbrain/pons (MP), but decreased in PUT, thalamus (THAL) and hypothalamus. D2R was unaltered throughout the nigrostriatal and mesolimbocortical system, while DA release was not different from controls in PUT, CAUD and NSTR, but elevated in VSTR. 5-HT2AR binding was unaltered in neocortex and cingulate. In acutely medicated adults, DAT was unaltered in PUT, but still increased in CAUD, whereas DA release remained unaltered throughout the nigrostriatal and mesolimbocortical system. When part of the patients was acutely medicated, vesicular monoamine transporter (VMAT2), DAT, SERT and DA synthesis were not different from controls in striatal regions, whereas D2R was decreased in NSTR, THAL, frontal cortex and limbic regions. Conversely, 5-HT2AR binding was unaltered in striatal regions and THAL, but increased in neocortical and limbic areas. It may be hypothesized that both the DA surplus and the 5-HT shortage in key regions of the nigrostriatal and mesolimbic system are relevant for the bouts of motor activity and the deficiencies in inpulse control.

Tics: neurological disorders determined by a deficit in sensorimotor gating processes. Neurol Sci 2022; 43:5839-5850.

Abstract
Tic related disorders affect 4–20% of the population, mostly idiopathic, can be grouped in a wide spectrum of severity, where the most severe end is Tourette Syndrome (TS). Tics are arrhythmic hyperkinesias to whom execution the subject is forced by a “premonitory urge” that can be classified as sensory tic, just-right experience or urge without obsession. If an intact volitional inhibition allows patients to temporarily suppress tics, a lack or deficit in automatic inhibition is involved in the genesis of the disorder. Studies have assessed the presence of intrinsic microscopic and macroscopic anomalies in striatal circuits and relative cortical areas in association with a hyperdopaminergic state in the basal forebrain. Prepulse inhibition (PPI) of the startle reflex is a measure of inhibitory functions by which a weak sensory stimulus inhibits the elicitation of a startle response determined by a sudden intense stimulus. It is considered an operation measure of sensorimotor gating, a neural process by which unnecessary stimuli are eliminated from awareness. Evidence points out that the limbic domain of the CSTC loops, dopamine and GABA receptors within the striatum play an important role in PPI modulation. It is conceivable that a sensorimotor gating deficit may be involved in the genesis of premonitory urge and symptoms. Therefore, correcting the sensorimotor gating deficit may be considered a target for tic-related disorders therapies; in such case PPI (as well as other indirect estimators of sensorimotor gating) could represent therapeutic impact predictors.

Abstract
Exposure and Response Prevention (ERP), Habit Reversal Training (HRT) and Comprehensive Behavioral Intervention for Tics (CBIT) are effective in reducing tic severity. ERP and HRT have recently gained primary support in a group setting, while CBIT has not been examined similarly. We compared the efficacy of group-CBIT to group-Educational Intervention for Tics (group-EIT) for tics and comorbid symptoms. Children with Tourette Syndrome (TS) or Chronic Tic Disorder (CTD) were randomized to group-CBIT or group-EIT. Tics and comorbid symptoms were assessed in forty-six children pre- and postintervention, and 3-month later. Yale Global Tic Severity Scale (YGTSS) Motor tic severity decreased following both interventions, and was maintained at follow-up for group-CBIT only. The Parent Tic Questionnaire (PTQ) showed significant decrease in total and motor tic severity following group-CBIT only, a gain maintained three months later. YGTSS impairment score decreased following both interventions and was maintained at follow-up. YGTSS vocal tic severity score increased following both interventions, and then decreased significantly at follow up. Co-morbid symptoms including anxiety, behavioral problems, and aggressive behavior decreased following both interventions. Children with behavioral problems benefitted less while children with higher intellectual ability benefit more from intervention. Both group interventions showed efficacy in reducing tic impairment and comorbid symptoms. Group-CBIT was superior to group-EIT in reducing motor tic severity at 3-month follow-up, showing an advantage for tic-focused treatment. Based on the PTQ, group-CBIT was superior to group-EIT in reducing motor, vocal, and total tic scores, a gain maintained three months later.

Abstract
BACKGROUND AND OBJECTIVES Behavioral therapies such as the Comprehensive Behavioral Intervention for Tics (CBIT) are recommended as the first-line treatment for Tourette's Disorder. This treatment approach is comprised of three central components: habit reversal training, functional assessment/intervention, and relaxation training. Despite its combined efficacy, the contribution of each therapeutic component in CBIT for reducing tic severity remains undetermined. The study evaluated the efficacy of relaxation training alone or alongside other CBIT components for reducing tic severity. METHODS In this multiple-baseline study, participants completed a baseline assessment (A), 4 weekly sessions of relaxation training followed by a posttreatment assessment (B), 8 weekly sessions of CBIT followed by a posttreatment assessment (C), and a 1 month posttreatment follow up assessment (D). Six participants (83% male) aged 10-18 with Tourette's Disorder completed study procedures. Primary outcomes of tic severity was the Yale Global Tic Severity Scale (YGTSS). RESULTS A repeated measures ANOVA revealed a significance reduction in tic severity over time (p = .010). While post-hoc tests revealed a moderate non-significant reduction in tic severity after relaxation training (d =.23), large significant reductions in tic severity were observed after the combined treatment of relaxation training and CBIT (d = 1.17) that were maintained at a 1-month follow-up visit (d = 1.53). LIMITATIONS Findings are limited by the small sample size. CONCLUSIONS While relaxation training is effective when included in conjunction with CBIT, relaxation training alone is not effective in reducing tic severity in patients with Tourette's Disorder.

Abstract
ObjectiveTo investigate the association between Group-A streptococcal (GAS) infections and tic incidence among unaffected children with a family history of chronic tic disorders (CTD).MethodsIn a prospective cohort study, children with no history for tics aged 3 to 10 years with a first-degree relative with CTD were recruited from the European Multicentre Tics in Children Study (EMTICS) across 16 European centres. Presence of GAS infection was assessed using throat swabs, serum Anti-streptolysin O titres (ASOT) and Anti-DNAse B (ADB) titres blinded to clinical status. GAS exposure was defined using four different definitions based on these parameters. Cox regression analyses with time-varying GAS exposure were conducted to examine the association of onset of tics and GAS exposure during follow-up. Sensitivity analyses were conducted using Cox regression and logistic regression analyses.ResultsA total of 260 children were recruited whilst one subject was found to have tic onsets before study entry and therefore was excluded. 61 children (23.6%) developed tics over an average follow-up period of 1 (SD 0.7) year. There was a strong association of sex and onset of tics, with girls having an approximately 60% lower risk of developing tics compared to boys (HR: 0.4, 95% CI 0.2-0.7). However, there was no statistical evidence to suggest an association of any of the four GAS exposure definitions with tic onset (GAS exposure definition 1: HR=0.310, 95% CI: 0.037-2.590; definition 2: HR=0.561, 95% CI: 0.219-1.436; definition 3: HR=0.853, 95% CI: 0.466-1.561; definition 4: HR=0.725, 95% CI: 0.384-1.370).ConclusionThese results do not suggest an association of GAS exposure and development of tics.Classification of EvidenceThis study provides Class I evidence that Group-A streptococcal exposure does not associate with the development of tics in children with first-degree relatives with chronic tic disorder.

Abstract
BACKGROUND The Jingxin Zhidong formula (JXZDF), a traditional Chinese medicine, has been widely used to treat tic disorder (TD) in China. However, its efficacy has not yet been evaluated in a randomized controlled trial. We aimed to compare the effectiveness and safety of JXZDF and aripiprazole in patients with TD. METHODS In this randomized, double-blind, double-dummy, parallel controlled trial, 120 patients with TD, aged 6-16 years were randomly assigned to receive either JXZDF (n = 60, 17.6 g/day) or aripiprazole (n = 60, 10 mg/day) for 12 weeks. The primary outcome was measured using the Yale Global Tic Severity Scale (YGTSS). Adverse events were assessed using the Treatment Emergent Symptom Scale. RESULTS JXZDF produced greater improvements than aripiprazole in the following YGTSS subscale scores at the endpoint: total tic scores (P = 0.004, 95% CI: 1.085-3.494) and total motor scores (P = 0.004, 95% CI: 0.313-1.739). The difference in rate between the groups was no significant (χ2 = 0.702, degrees of freedom = 1, P = 0.402). The overall incidence of adverse events was significantly lower in the JXZDF group than in the aripiprazole group (0% vs 6.67%, P < 0.001). CONCLUSION JXZDF had a better safety profile than aripiprazole, and it was not inferior in terms of clinical efficacy. JXZDF warrants consideration as a potential treatment option for TD.

Abstract
OBJECTIVE There are few effective pharmacological treatments for Tourette's syndrome. Many patients with Tourette's syndrome experience impairing tic symptoms despite use of available evidence-based treatments. The investigators conducted a small, uncontrolled trial to examine the safety, tolerability, and dosing of THX-110, a combination of Δ9-tetrahydracannabinol (Δ9-THC) and palmitoylethanolamide (PEA), in Tourette's syndrome. METHODS A 12-week uncontrolled trial of THX-110 (maximum daily Δ9-THC dose, 10 mg, and a constant 800-mg dose of PEA) in 16 adults with Tourette's syndrome was conducted. The primary outcome was improvement on the Yale Global Tic Severity Scale (YGTSS) total tic score. Secondary outcomes included measures of comorbid conditions and the number of participants who elected to continue treatment in the 24-week extension phase. RESULTS Tic symptoms significantly improved over time with THX-110 treatment. Improvement in tic symptoms was statistically significant within 1 week of starting treatment compared with baseline. THX-110 treatment led to an average improvement in tic symptoms of more than 20%, or a 7-point decrease in the YGTSS score. Twelve of the 16 participants elected to continue to the extension phase, and only two participants dropped out early. Side effects were common but were generally managed by decreasing Δ9-THC dosing, slowing the dosing titration, and shifting dosing to nighttime. CONCLUSIONS Although the initial data from this trial in adults with refractory Tourette's syndrome are promising, future randomized double-blind placebo-controlled trials are necessary to demonstrate efficacy of THX-110 treatment. The challenges raised by the difficulty in blinding trials due to the psychoactive properties of many cannabis-derived compounds need to be further appreciated in these trial designs.

Abstract
Tourette syndrome (TS) is a childhood-onset, chronic neuropsychiatric disorder characterized by multiple motor and vocal tics. TS poses a considerable burden on both patients and health care providers, leading to a major detriment of educational success, occupation, and interpersonal relationships. A multidisciplinary, specialist-driven management approach is required due to the complexity of TS. However, access to such specialty care is often dramatically limited by the patients' locations and the specialists' geographic clustering in large urban centers. Telemedicine uses electronic information and communication technology to provide and support health care when distance separates participants. Therefore, we conducted this mini-review to describe the latest information on telemedicine in the assessment and management of TS and discuss the potential contributions to care for TS patients with a multidisciplinary approach. We believe that telemedicine could be a revolutionary method in improving medical access to patients with TS.

Abstract
OBJECTIVES Nearly half of the patients with Tourette Syndrome (TS) present with comorbid Obsessive-Compulsive Symptoms (OCS) and premonitory urges (PUs). However, inconsistent results have been found in the correlation between PUs and OCS in patients with TS. METHODS A meta-analysis was applied to identify the severity of OCS and its correlation with PUs in TS patients. Subgroup and meta-regression analyses were used to identify potential heterogeneity. RESULTS A total of 13 studies, including 576 patients, were enrolled in this study. The pooled correlation coefficient (r) was 0.29 (95% confidence interval: 0.18, 0.38) and heterogeneity (I2) of pooled r was 40% based on a fixed-effect model. The mean level of OCS based on the assessment of Children's Yale-Brown Obsessive-Compulsive Symptom Scale/Yale-Brown Obsessive-Compulsive Symptom Scale was 14.99 (95% CI: 11.41, 18.57) by a random effect model. Results of meta-regression analysis demonstrated that the severity of tic symptoms based on the assessment of the Yale Global Tic Severity Scale was the predictor of severity of OCS (p = 0.018). CONCLUSION There was a mild positive correlation between the PUs and OCS in patients with TS. The severity of OCS in TS patients was mild to moderate and positively predicted by the severity of tic symptoms.

Abstract
Purpose of Review Pediatricians and other primary care providers are often the first and sole healthcare clinicians of patients who present with tics. However, limited primary care pediatric training in neuropsychiatric concerns, as well as perceived lack of comfort and preparation, make it challenging for these clinicians to confidently identify and manage tic disorders. Recent Findings Current empirical findings of tic disorder management relevant to pediatric physicians, including assessment, psychoeducation, behavioral interventions, psychotropic medications, and alternative treatments are reviewed. Summary This article discusses neuropsychiatric and medical complexities of tic disorder assessment, with particular emphasis on differential and comorbid diagnoses. Tiered referral recommendations, based on symptom severity, impairment, and consideration of comorbid conditions, are provided. Future directions for tic management, including dissemination of evidence-based treatments of tic disorders and multidisciplinary teams within pediatric primary care settings, are included.

Abstract
BACKGROUND Tourette syndrome (TS) is often comorbid with attention deficit hyperactivity disorder, obsessive-compulsive disorder, and depression. Medications are the main treatment for TS. Relationships between TS medication therapy and psychiatric comorbidities remain unclear. This study explored the impacts of TS medication on the risk of psychiatric comorbidities using a nationally representative sample of TS in Taiwan. METHODS Data from National Health Insurance Research Database in Taiwan was used to identify 997,213 children and adolescents aged 6-18 years who had received a diagnosis of TS based on ICD-9-CM codes in 2000-2010. Cox's proportional hazard regression analysis was conducted to estimate the risk of comorbidities among subjects with and without tic medication therapy. RESULTS We found that in TS patients, a lower risk of psychiatric comorbidities occurred in the tic medication therapy group (p = 0.012) and the crude hazard ratio (HR) was 0.6 (95% confidence interval (CI) = 0.4-0.8, p < 0.001). After adjusting for potential confounders of gender, age, income, level of care, department visited, brain injury, and the number of suicide attempts, the risk of comorbidities was still significantly lower in the tic medication therapy group (adjusted HR = 0.5, 95% CI = 0.3-0.6, p < 0.001). DISCUSSION One limitation was that we did not include all mediations used to treat psychiatric comorbidities among TS patients. This study found the effectiveness of TS medications on improving psychiatric comorbidities. CONCLUSIONS Compared to those without medication, medication therapy appears to have a benefit of decreasing the risk of psychiatric comorbidities. Strategies to improve medication regimens should be considered in clinical settings.

Abstract
Tourette syndrome is a neurodevelopmental disorder which is characterized by the presence of motor and phonic tics. These tics are generally more prevalent in childhood. Tics typically reach their maximum severity before puberty, around age 10 to 12. In most patients, tic severity usually decreases during late adolescence and adulthood. However, this is not true for all individuals. To date, the developmental trajectory leading to the persistence of tics into adulthood is still poorly understood. There are very few markers that can predict the evolution of tic symptoms from childhood to adulthood. Yet, while we cannot cure Tourette syndrome, it is possible to reduce tic severity with various treatments. The most common treatments are pharmacotherapy and behavioral and cognitive-behavioral therapy. However, there appears to be a limit to the proportion of tics that can be treated, since most treatments offer an average reduction in tics of no more than 50%. Thus, at first, this article reviews recent advances in treatment and symptom progression. Next, we propose some lines of research to improve the management and treatment of people with Tourette syndrome.

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

Abstract
AIM The diagnosis and management of tic disorders and Tourette syndrome (TS) can be challenging. A better understanding of current approaches by paediatricians is important to inform research and education to improve patient outcomes. We aimed to investigate current assessment and management practices for tics/TS by Australian paediatricians. METHODS An online survey was sent to members of the Australian Paediatric Research Network. Primary outcomes of interest included assessment processes, referrals, behavioural interventions and pharmacological management. Four scenarios were presented to elicit information regarding treatment of different types of cases. RESULTS Of 340 eligible paediatricians, 139 (41%) responded, with 116 (84%) reporting that they diagnose and manage tics/TS as part of their practice. Questionnaires were used more to identify comorbidities (43%) than to quantify tics (12%). Referrals were most likely to be made to psychologists. Medication was considered important in the management of TS by 45% of respondents, with clonidine identified as the first-choice medication by 69%. There was wide variation in both the pharmacological and behavioural management strategies reported. CONCLUSIONS There is substantial practice variation among Australian paediatricians in the assessment and management of patients referred with tics/TS. This may reflect insufficient evidence regarding best practice, as well as limited training in this area. There is a need for improved education of Australian paediatricians in the assessment and management of tics/TS, as well as further research to identify optimal treatments.

Abstract
The objective of this study is to report the effects of low-frequency repetitive transcranial magnetic stimulation (rTMS) in three patients with medication-refractory Tourette syndrome (TS) and over 3-month follow-up. A review of literature on the use of rTMS for the treatment of TS is also presented. Three patients with severe, medication-refractory TS and comorbid obsessive-compulsive disorder (OCD) in two of them, received an open-label trial of rTMS at 1 Hz frequency for 4-week duration. The first two cases of TS-OCD showed, on average, around 57% improvement in Yale Global Tic Severity Scale (YGTSS) scores (65% and 50%) and 45% improvement in Yale-Brown Obsessive-compulsive Scale (Y-BOCS) scores; however, the third case of pure-TS showed marginal improvement of 10% only. The improvement in TS-OCD patients with rTMS treatment was maintained at the end of 3-month follow-up, with an average reduction of about 49% (58% and 40%) and 36% observed in YGTSS and Y-BOCS scores, respectively. The present study supports the use of low-frequency rTMS to improve tics and OCD symptoms in patients with severe, medication-refractory TS-OCD. Further, the beneficial effects of rTMS treatment were maintained substantially over 3-month follow-up period.

Abstract
The purpose of present study was to infer the potential effects of testosterone increase in some male-based childhood-onset neuropsychiatric disorders, such as Tourette syndrome. Thus, the influence of early postnatal androgen exposure upon the neurobehaviors and its possible neural basis were investigated in the study. Male pup rats received consecutive 14-day testosterone propionate (TP) subcutaneous injection from postnatal day (PND) 7. The TP treatment produced the hyperactive motor behavior and grooming behavior as well as the increased levels of dopamine, tyrosine hydroxylase and dopamine transporter in the mesodopaminergic system and the elevated levels of serotonin in the nucleus accumbens, without affecting the levels of glutamate, γ-aminobutyric acid, norepinephrine and histamine in the caudate putamen and nucleus accumbens of PND21 and PND49 rats. Dopamine D2 receptor antagonist haloperidol was administered to the early postnatal TP-exposed PND21 and PND49 male rats 30 min prior to open field test. Haloperidol significantly ameliorated the motor behavioral and grooming behavioral defects induced by early postnatal TP exposure. The results demonstrated that early postnatal androgen exposure significantly disturbed the brain activity of developing male rats via enhancing the mesodopaminergic activity. It was suggested that abnormal increments of testosterone levels during the early postnatal development might be a potential risk factor for the incidence of some male-based childhood-onset neuropsychiatric disorders by affecting the mesodopaminergic system.

Abstract
Motor tics are sudden, repetitive, involuntary movements representing the hallmark behaviors of the neurodevelopmental disease Tourette’s syndrome (TS). The primary cause of TS remains unclear. The initial observation that dopaminergic antagonists alleviate tics led to the development of a dopaminergic theory of TS etiology which is supported by post mortem and in vivo studies indicating that non-physiological activation of the striatum could generate tics. The striatum controls movement execution through the balanced activity of dopamine receptor D1 and D2-expressing medium spiny neurons of the direct and indirect pathway, respectively. Different neurotransmitters can activate or repress striatal activity and among them, dopamine plays a major role. In this study we introduced a chronic dopaminergic alteration in juvenile rats, in order to modify the delicate balance between direct and indirect pathway. This manipulation was done in the dorsal striatum, that had been associated with tic-like movements generation in animal models. The results were movements resembling tics, which were categorized and scored according to a newly developed rating scale and were reduced by clonidine and riluzole treatment. Finally, post mortem analyses revealed altered RNA expression of dopaminergic receptors D1 and D2, suggesting an imbalanced dopaminergic regulation of medium spiny neuron activity as being causally related to the observed phenotype.

Abstract
This paper examined neurocognitive functioning and its relationship to behavior treatment response among youth with Tourette's Disorder (TD) in a large randomized controlled trial. Participants diagnosed with TD completed a brief neurocognitive battery assessing inhibitory functions, working memory, and habit learning pre- and post-treatment with behavior therapy (CBIT, Comprehensive Behavioral Intervention for Tics) or psychoeducation plus supportive therapy (PST). At baseline, youth with tics and Attention Deficit Hyperactivity Disorder (ADHD) exhibited some evidence of impaired working memory and simple motor inhibition relative to youth with tics without ADHD. Additionally, a small negative association was found between antipsychotic medications and youth's performance speed. Across treatment groups, greater baseline working memory and aspects of inhibitory functioning were associated with a positive treatment response; no between-group differences in neurocognitive functioning at post-treatment were identified. Within the behavior therapy group, pre-treatment neurocognitive status did not predict outcome, nor was behavior therapy associated significant change in neurocognitive functioning post-treatment. Findings suggest that co-occurring ADHD is associated with some impairments in neurocognitive functioning in youth with Tourette's Disorder. While neurocognitive predictors of behavior therapy were not found, participants who received behavior therapy exhibited significantly reduced tic severity without diminished cognitive functioning.

Abstract
Anecdotal reports frequently suggest some dietary involvement in the maintenance of tics in children with Tourette syndrome (TS). This scoping review aimed to (1) understand the possible influence of diet as a trigger of tics and (2) map out the existing studies documenting dietary interventions in children with TS. Current evidence suggests no single diet to benefit individuals with TS. However, reports from parents of children with TS suggest that certain allergens in food may exacerbate tic-related symptoms. For example, an increase in tics has been related to the consumption of caffeine and refined sugar. Moreover, oligoantigenic diets and sugar-free diets have been identified as significantly reducing tics. More research is urgently needed to develop more accurate guidance for parents and children with TS, as many have reported using dietary and nutritional supplements, despite the lack of evidence detailing any benefits, side effects and recommended doses.

Abstract
OBJECTIVE To evaluate the tolerability, safety, and preliminary efficacy of extended-release guanfacine in children with chronic tic disorders, including Tourette's disorder (collectively referred to as CTD). METHODS This was a multisite, 8-week, randomized, double-blind, placebo-controlled trial. The primary outcome measure was the Yale Global Tic Severity Scale (YGTSS) total score. Key secondary outcomes included the Improvement item of Clinical Global Impressions-Improvement (CGI-I) scale and the Tic Symptom Self-report (TSSR). Adverse events were monitored at each visit. RESULTS Thirty-four subjects (23 boys and 11 girls) of ages 6 to 17 years (mean = 11.1 ± 3.1) with CTD were randomly assigned to extended-release guanfacine (n = 16) or placebo (n = 18). At baseline, the mean YGTSS total score was 26.3 ± 6.6 for the guanfacine group versus 27.7 ± 8.7 for the placebo group. Within the guanfacine group (mean final daily dose of 2.6 ± 1.1 mg, n = 14), the mean YGTSS total score declined to 23.6 ± 6.42 [t(15) = 1.84, p = 0.08; effect size = 0.35]. The results were similar in the placebo group with a score of 24.7 ± 10.54 at week 8 [t(17) = 1.83, p = 0.08; effect size = 0.38]. There was no significant difference in the rate of positive response on the CGI-I between the guanfacine group and placebo (19% [3/16] vs. 22% [4/18], p = 1.0). The most common adverse events were fatigue, drowsiness, dry mouth, headache, and irritability. Two subjects in the guanfacine group discontinued early-one because of an adverse event (depressed mood) and one because of lack of efficacy; two subjects in the placebo group discontinued because of lack of efficacy. CONCLUSIONS This pilot study did not confirm a clinically meaningful effect size within the guanfacine group. These results do not support the launch of a larger efficacy trial for tics in children and adolescents with CTD.

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
For many years, Tourette syndrome (TS) was considered to be a rare disorder, but tics and TS are now recognized as fairly common childhood-onset conditions. Children and adolescents with TS are frequently treated with antipsychotics, either as monotherapy or in combination with psychostimulants, melatonin and selective serotonin reuptake inhibitors (SSRIs). Antipsychotics are most often used in schizophrenia and related psychotic disorders, and in these conditions hyperprolactinemia is one of the most common adverse effects associated with antipsychotics, occurring in 40-50% of patients. We describe two patients with TS who experienced antipsychotic-induced hyperprolactinemia. Treatment options generally consist of dose reduction or switching from typical to atypical antipsychotics. However, diminishing dosages can lead to exacerbations of tics. Also, not all atypical antipsychotics have the same pharmacologic properties required to normalize prolactin levels. The choice of treatment may also be affected by the patient's age and sex. These factors are discussed in relation to these cases, and illustrated by the results of therapeutic interventions over the years.

Abstract
Tourette syndrome (TS) is a neuropsychiatric disorder involving motor and phonic tics. Inhibitory control is a key issue in TS, and many disruptive or impulsive behaviors might arise from inhibitory deficits. However, conflicting findings regarding TS patients' inhibitory performance in neuropsychological tasks have been reported throughout the literature. Therefore, this meta-analysis aimed to evaluate inhibitory control through neuropsychological tasks, and to analyze the factors modulating inhibitory deficits. To this end, a literature search was performed through MEDLINE and PsycINFO, to retrieve studies including neuropsychological tasks that assessed inhibitory control in TS patients. Of the 4020 studies identified, 61 were included in the meta-analysis, for a total of 1717 TS patients. Our analyses revealed a small to medium effect in favor of inhibitory deficits in TS patients. This effect was larger in TS+ADHD patients, but pure TS patients also showed some inhibitory deficits. Therefore, deficits in inhibitory control seem to be an inherent component of TS, and are exacerbated when ADHD is concomitant.

Abstract
This study assesses the risk of fractures among children with Tourette syndrome (TS), and identifies the effects of comorbidities and antipsychotics. We randomly sampled the claims data of 1 million enrollees in the National Health Insurance program of Taiwan, and identified 1258 children with TS diagnosed between 2000 and 2010. Additionally, 12,580 children without TS who were frequency matched for sex, age, residential area, parental occupation, and index year were identified for comparison. The children's cases were followed until December 31, 2010, or censored to ascertain incident fractures cases and associations with comorbidities of attention-deficit/hyperactivity disorder (ADHD) or obsessive-compulsive disorder (OCD) and treatments with antipsychotics, antidepressants, or clonidine. The TS cohort had a 1.27-fold higher incidence of fractures than did the comparison cohort (190.37 vs. 149.94 per 10,000 person-years), with an adjusted hazard ratio (HR) of 1.28 [95% confidence interval (CI) 1.06-1.55] based on multivariable Cox regression analysis. This increased risk of fractures was apparent for fractures of the skull, neck, and spine. Comorbid ADHD and OCD did not result in an additional risk of fractures. The children without both ADHD and OCD were also at a higher risk of fractures, indicating that TS alone increases the risk of fractures. The children taking antipsychotics had a reduced risk of fractures, and the adjusted HR decreased to 1.17 (95% CI 0.90-1.52). Children with TS have an increased risk of fractures. ADHD and OCD do not increase the risk further.

Abstract
Persistent tic disorders and Tourette disorder (TD) are neuropsychiatric conditions that commonly co-occur among youth with obsessive-compulsive disorder. Although historically managed with pharmacological agents such as antipsychotics and alpha-2 agonists, behavioral interventions like habit reversal training (HRT) and the comprehensive behavioral intervention for tics have demonstrated considerable efficacy in reducing tic symptom severity. This case study illustrates the implementation of behavior therapy in reducing tic symptom severity of an adolescent with TD. Arlene was a 14-year-old girl with TD who presented with moderate tic symptom severity that caused her physical, academic, and social impairment. In addition to concurrent pharmacotherapy, Arlene completed a 20-session weekly course of HRT, and experienced a clinically meaningful reduction in tic symptom severity and tic-related impairment. This example provides further evidence of the benefit of behavior therapy in reducing tic symptom severity and highlights key considerations for treatment of youth with TD.

Abstract
Accumulating evidence suggests that Tourette's Syndrome (TS) - a multifactorial pediatric disorder characterized by the recurrent exhibition of motor tics and/or vocal utterances - can partly depend on immune dysregulation provoked by early repeated streptococcal infections. The natural and adaptive antibody-mediated reaction to streptococcus has been proposed to potentially turn into a pathological autoimmune response in vulnerable individuals. Specifically, in conditions of increased permeability of the blood brain barrier (BBB), streptococcus-induced antibodies have been proposed to: (i) reach neuronal targets located in brain areas responsible for motion control; and (ii) contribute to the exhibition of symptoms. This theoretical framework is supported by indirect evidence indicating that a subset of TS patients exhibit elevated streptococcal antibody titers upon tic relapses. A systematic evaluation of this hypothesis entails preclinical studies providing a proof of concept of the aforementioned pathological sequelae. These studies shall rest upon individuals characterized by a vulnerable immune system, repeatedly exposed to streptococcus, and carefully screened for phenotypes isomorphic to the pathological signs of TS observed in patients. Preclinical animal models may thus constitute an informative, useful tool upon which conducting targeted, hypothesis-driven experiments. In the present review we discuss the available evidence in preclinical models in support of the link between TS and pediatric autoimmune neuropsychiatric disorders associated with streptococcus infections (PANDAS), and the existing gaps that future research shall bridge. Specifically, we report recent preclinical evidence indicating that the immune responses to repeated streptococcal immunizations relate to the occurrence of behavioral and neurological phenotypes reminiscent of TS. By the same token, we discuss the limitations of these studies: limited evidence of behavioral phenotypes isomorphic to tics and scarce knowledge about the immunological phenomena favoring the transition from natural adaptive immunity to pathological outcomes.

Abstract
The association between epilepsy and Tourette syndrome has rarely been investigated. In this retrospective cohort study, we analyzed a dataset of 1,000,000 randomly sampled individuals from the Taiwan National Health Insurance Research Database to determine the risk of epilepsy in children with Tourette syndrome. The study cohort consisted of 1062 patients with Tourette syndrome aged ≤ 18 years, and the control group consisted of three times the number of age- and sex-matched patients without Tourette syndrome, who were insurants, from the same database during the same period. The Tourette syndrome group had an 18.38-fold increased risk of epilepsy than the control group [hazard ratio=18.38, 95% confidence interval (CI)=8.26-40.92; P<0.001]. Even after adjusting for the comorbidities, the risk of epilepsy in the Tourette syndrome group with comorbidities remained high (hazard ratio=16.27, 95% CI=6.26-18.46; P<0.001), indicating that the increased risk was not associated with comorbidities. This population-based retrospective cohort study provides the first and strong evidence that Tourette syndrome is associated with a higher risk of epilepsy. A close follow-up of children with Tourette syndrome for the development of epilepsy is warranted.

Abstract
INTRODUCTION Comprehensive Behavioral Intervention for Tics (CBIT) has been shown to be efficacious for chronic tic disorders (CTDs), but utilization is limited by a lack of treatment providers and perceived financial and time burden of commuting to treatment. A promising alternative to in-person delivery is voice over Internet protocol (VoIP), allowing for remote, real-time treatment delivery to patients' homes. However, little is known about the effectiveness of VoIP for CTDs. Therefore, the present study examined the preliminary efficacy, feasibility, and acceptability of VoIP-delivered CBIT (CBIT-VoIP). METHODS Twenty youth (8-16 years) with CTDs participated in a randomized, waitlist-controlled pilot trial of CBIT-VoIP. The main outcome was pre- to post-treatment change in clinician-rated tic severity (Yale Global Tic Severity Scale). The secondary outcome was clinical responder rate (Clinical Global Impressions - Improvement Scale), assessed using ratings of 'very much improved' or 'much improved' indicating positive treatment response. RESULTS Intention-to-treat analyses with the last observation carried forward were performed. At post-treatment (10-weeks), significantly greater reductions in clinician-rated, (F(1,18) = 3.05, p < 0.05, partial η(2 )= 0.15), and parent-reported tic severity, (F(1,18) = 6.37, p < 0.05, partial η(2 )= 0.26) were found in CBIT-VoIP relative to waitlist. One-third (n = 4) of those in CBIT-VoIP were considered treatment responders. Treatment satisfaction and therapeutic alliance were high. DISCUSSION CBIT can be delivered via VoIP with high patient satisfaction, using accessible, low-cost equipment. CBIT-VoIP was generally feasible to implement, with some audio and visual challenges. Modifications to enhance treatment delivery are suggested.

Abstract
We were delighted to read the letter by Dr. Theule and colleagues (Theule et al., 2016) commenting on our meta-analysis of behavior therapy for Tourette Syndrome (TS)(McGuire et al., 2014). We welcome this discussion, and were interested to learn of their related meta-analysis on psychosocial treatments for tic disorders. This commentary addresses the similarities and distinctions between these two meta-analytic investigations, and concludes with recommendations regarding the future of treatment research for TS.

Abstract
Tourette syndrome (TS) is a neurodevelopmental disorder characterized by multiple chronic motor and vocal tics beginning in childhood. Several studies describe the association between TS and attention deficit hyperactivity disorder (ADHD). Fifty percent of children diagnosed with ADHD have comorbid tic disorder. ADHD related symptoms have been reported in 35% to 90% of children with TS. Since ADHD is the most prevalent comorbid condition with TS and those with concomitant TS and ADHD present with considerable psychosocial and behavioral impairments, it is essential for clinicians to be familiar with these diagnoses and their management. This paper highlights the association between treating ADHD with stimulants and the development of tic disorders. The two cases discussed underscore the fact that children with TS may present with ADHD symptomatology prior to the appearance of any TS related symptoms. Appropriate management of TS in a patient diagnosed with ADHD can lead to quality of life improvements and a reduction in psychosocial impairments.

Abstract
Over the past six decades, behavior therapy has been a major contributor to the development of evidence-based psychotherapy treatments. However, a long-standing concern with behavior therapy among many nonbehavioral clinicians has been the potential risk for symptom substitution. Few studies have been conducted to evaluate symptom substitution in response to behavioral treatments, largely due to measurement and definitional challenges associated with treated psychiatric symptoms. Given the overt motor and vocal tics associated with Tourette's disorder, it presents an excellent opportunity to empirically evaluate the potential risk for symptom substitution associated with behavior therapy. The present study examined the possible presence of symptom substitution using four methods: (a) the onset of new tic symptoms, (b) the occurrence of adverse events, (c) change in tic medications, and (d) worsening of co-occurring psychiatric symptoms. Two hundred twenty-eight participants with Tourette's disorder or persistent motor or vocal tic disorders were randomly assigned to receive behavioral therapy or supportive therapy for tics. Both therapies consisted of eight sessions over 10 weeks. Results indicated that participants treated with behavior therapy were not more likely to have an onset of new tic symptoms, experience adverse events, increase tic medications, or have an exacerbation in co-occurring psychiatric symptoms relative to participants treated with supportive therapy. Further analysis suggested that the emergence of new tics was attributed with the normal waxing and waning nature of Tourette's disorder. Findings provide empirical support to counter the long-standing concern of symptom substitution in response to behavior therapy for individuals with Tourette's disorder.

Abstract
Pharmacological treatments for Tourette syndrome (TS) vary in efficacy between different patients. The evidence base is limited as even high quality controlled studies tend to be of relatively short duration which may lose relevance in clinical usage. Patients are frequently treated with serial agents in the search for efficacy and tolerability. The success of this strategy has not been previously documented. We examined 400 consecutive TS patients seen over a 10-year period, some with a longer prior history in other clinics; 255/400 (64%) were prescribed medication. We present this heterogeneous cohort in terms of the number of drugs they had tried, and as a proxy measure of some benefit of the last drug used, whether it had been prescribed under our supervision for ≥ 5 months. The most commonly prescribed medications were aripiprazole (64%), clonidine (40%), risperidone (30%) and sulpiride (29%) with changes in prescribing practises over the period examined. The number of different drugs tried were one (n = 155), two (n = 69), three (n = 36), four (n = 14), five (n = 15), six (n = 5), seven (n = 2) and eight (n = 1). The data illustrate the difficulty in drug treatment of tics and suggest that even after trials of several agents there is potential benefit in trying further options.

Abstract
Tourette Syndrome (ts) is a developmental neuropsychiatric disorder of the central nervous system defined by the presence of chronic tics. While investigations of the underlying brain mechanisms have provided valuable information, a complete understanding of the pathophysiology of ts remains elusive. Neuroimaging methods provide remarkable tools for examining the human brain, and have been used to study brain structure and function in ts. In this article, we review ts neuroimaging studies published in 2014-2015. We highlight a number of noteworthy studies due to their innovative methods and interesting findings. Yet, we note that many of the recent studies share common concerns, specifically susceptibility to motion artifacts and modest sample sizes. Thus, we encourage future work to carefully address potential methodological confounds and to study larger samples to increase the potential for replicable results.

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.
