Abstract
BACKGROUND Attention-deficit/hyperactivity disorder (ADHD) and persistent tic disorder (PTD) are two neurodevelopmental disorders that frequently co-occur. Contributions of each disorder to cognitive and behavioral deficits have been reported. In this paper, we tested 3 models of pathophysiology for the two disorders (additive, interactive, and phenotypic) using resting-state connectivity associated with each disorder separately and together. METHODS Participants were 148 children (55 with ADHD only, 33 with ADHD and PTD, 27 with PTD only, and 33 healthy control subjects) at ages 8 to 12 years. Following diagnostic interviews and behavioral assessment, participants underwent a 128-channel electroencephalography recording. Resting-state, cortical source-level effective connectivity was analyzed across the 4 groups using a 2 × 2 factorial design with factors of ADHD (with/without) and PTD (with/without). RESULTS ADHD diagnosis was the primary driver of cognitive and behavioral deficits, while deficits associated with PTD were primarily with thought problems and internalizing problems when compared with controls. Subadditive effects were observed in co-occurring ADHD+PTD for parent-rated behavioral problems and cognitive functions. Aberrant effective connectivity was primarily associated with ADHD, more specifically with lower posterior and occipital-frontal connectivity, while children with PTD exhibited greater left postcentral to precuneus connectivity. Weaker ADHD-related connectivity was associated with more severe behavioral problems, including internalizing behaviors, thought problems, and working memory deficits. CONCLUSIONS Similar to general behavioral deficits, aberrant resting-state neural connectivity in pediatric ADHD and PTD combines additively in co-occurring cases. The findings of this study support ADHD as a focus of treatment in comorbid cases, given the driving role of ADHD in both behavioral and neurophysiological deficits.

Abstract
Neurodevelopmental disorders (NDDs) encompass a group of complex conditions with onset during the early developmental period. Such disorders are frequently associated with a number of neuropsychiatric features, the most prevalent ones being autism spectrum disorder, attention-deficit/hyperactivity disorder, intellectual disability, communication and specific learning disorders, and motor disorders. These conditions are characterized by wide genetic and clinical variability, and although they were previously conceptualized as childhood-limited disorders, NDDs are progressively being recognized as persistent conditions with a potentially relevant impact on the quality of life and overall functioning during adult life. In addition, emerging evidence seems to point towards the hypothesis of a neurodevelopmental continuum, according to which NNDs could portray different time-dependent outcomes, depending on the severity of the altered brain development. Despite representing lifelong phenotypes, they are often not promptly identified and/or managed in adulthood. In this regard, specific guidelines on clinical and therapeutic approaches for these conditions have not yet been delineated. In this view, future research investigations should be encouraged to broaden available knowledge, characterize the clinical course of NDDs across an individual’s lifespan, and better understand the patterns of aging-related concerns in adults with an NDD diagnosis. Additionally, considering the difficulties many young adults encounter while transitioning from childhood to adult mental health services, new, specific programs should be developed and existing programs should be implemented to improve the transition process and for the management of NDDs in adulthood.

Abstract
INTRODUCTION Autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) share overlapping symptomatology, particularly with regard to social impairments (including peer relationship difficulties), and they frequently co-occur. However, the nature of their co-occurrence remains unclear. Therefore, the current study aimed to examine the nature of the transdiagnostic link between ASD and ADHD from a symptomatological point of view measured with the Autism Diagnostic Observation Schedule (ADOS Module 3) and the Autism Diagnostic Interview-Revised (ADI-R). METHODS We analyzed the social and nonsocial ASD symptom domain scores from both diagnostic instruments in 4 clinically referred groups (i.e., ASD, ADHD, ASD + ADHD, and no psychiatric diagnosis) without other co-occurring mental disorders using a two-by-two full-factorial MANOVA design with the factors ASD (yes/no) and ADHD (yes/no). RESULTS We found no ASD by ADHD interaction effects across all symptom domain scores of ADOS and ADI-R, except for ADOS imagination/creativity. There were only main effects of the factor ASD but no main effects of ADHD. Follow-up contrasts showed that exclusively, ASD had an impact on the measured symptomatology in case of co-occurring ASD + ADHD. CONCLUSION Overall, the results support an additive model of the symptomatology across areas of communication, social interaction, and stereotyped behaviors and restricted interests in case of the co-occurrence of ASD and ADHD when assessed with ADOS/ADI-R. Thus, one can assume that the phenotypic overlap of ASD + ADHD may be less complicated than suspected - at least with regard to ASD symptomatology - and that in the presence of ADHD, ASD symptomatology is generally well measurable with best-practice diagnostic instruments.

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

Dysregulation profile (DP) as a transdiagnostic psychopathological factor in clinically referred children - comparisons between disorders and latent structure. Nord J Psychiatry 2022; 76:71-79.

Abstract
BACKGROUND Dysregulation Profile (DP) describes the psychopathological construct of concurrent impairments in the ability to regulate emotion, behaviour, and cognition measured by the Child Behaviour Checklist (CBCL). Such transdiagnostic dimensions of psychopathology play an important role in addition to core symptoms of psychiatric diagnosis in clinical practice. Evaluation of DP in children with different mental disorders may improve our understanding and treatment of both contents. METHODS 911 clinically referred children between 6 and 18 years were investigated. The sample consisted of five 'pure' disorders groups, that is, tic disorder (TIC), anxiety disorder, obsessive compulsive disorder, depression, Attention Deficit Hyperactivity Disorder (ADHD), and two comorbid disorder group, that is, ADHD + TIC and ADHD + oppositional defiant disorder (ODD). DP level and latent structure were compared across groups. RESULTS The rate of severe/abnormal dysregulation rates varied from 15% to 44% when the 210 cut-off was used, and 5% to 18% when stringent cut-off was used (i.e. ≥70 on all DP-subscales). The most affected population were children with comorbid ADHD with ODD/TIC, while least were those with TIC only. Five different latent phenotypes of DP were found. CONCLUSION DP above clinical cut-off level widely exists in clinically referred children in parallel to core symptoms of their diagnosis, especially among children with comorbidities. During clinical assessment it would be worth to clarify the role of DP-related problems within the general psychosocial impairment of the patient to improve a personalized approach.

Abstract
In 2011, the European Society for the Study of Tourette Syndrome (ESSTS) published the first European guidelines for Tourette Syndrome (TS). We now present an update of the part on pharmacological treatment, based on a review of new literature with special attention to other evidence-based guidelines, meta-analyses, and randomized double-blinded studies. Moreover, our revision took into consideration results of a recent survey on treatment preferences conducted among ESSTS experts. The first preference should be given to psychoeducation and to behavioral approaches, as it strengthens the patients' self-regulatory control and thus his/her autonomy. Because behavioral approaches are not effective, available, or feasible in all patients, in a substantial number of patients pharmacological treatment is indicated, alone or in combination with behavioral therapy. The largest amount of evidence supports the use of dopamine blocking agents, preferably aripiprazole because of a more favorable profile of adverse events than first- and second-generation antipsychotics. Other agents that can be considered include tiapride, risperidone, and especially in case of co-existing attention deficit hyperactivity disorder (ADHD), clonidine and guanfacine. This view is supported by the results of our survey on medication preference among members of ESSTS, in which aripiprazole was indicated as the drug of first choice both in children and adults. In treatment resistant cases, treatment with agents with either a limited evidence base or risk of extrapyramidal adverse effects might be considered, including pimozide, haloperidol, topiramate, cannabis-based agents, and botulinum toxin injections. Overall, treatment of TS should be individualized, and decisions based on the patient's needs and preferences, presence of co-existing conditions, latest scientific findings as well as on the physician's preferences, experience, and local regulatory requirements.

Abstract
Objective Attention-deficit/hyperactivity disorder (ADHD) and tic disorder (TD) are among the most common comorbid psychopathologies and have a shared genetic basis. The psychopathological and neurophysiological aspects of the mechanism underlying the comorbidity of both disorders have been investigated, but the pathophysiological aspects remain unclear. Therefore, this study aimed to compare the neurophysiological characteristics of ADHD with those of TD using resting-state electroencephalography and exact low-resolution brain electromagnetic tomography (eLORETA) analysis. Methods We performed eLORETA analysis based on the resting-state scalp-recorded electrical potential distribution in 34 children with ADHD and 21 age-matched children with TD. Between-group differences in electroencephalography (EEG) current source density in delta, theta, alpha, beta, and gamma bands were investigated in each cortical region. Results Compared with the TD group, the ADHD group showed significantly increased theta activity in the frontal region (superior frontal gyrus, t = 3.37, p < 0.05; medial frontal gyrus, t = 3.35, p < 0.05). In contrast, children with TD showed decreased posterior alpha activity than those with ADHD (precuneus, t = −3.40, p < 0.05; posterior cingulate gyrus, t = −3.38, p < 0.05). These findings were only significant when the eyes were closed. Conclusion Increased theta activity in the frontal region is a neurophysiological marker that can distinguish ADHD from TD. Also, reduced posterior alpha activity might represent aberrant inhibitory control. Further research needs to confirm these characteristics by simultaneously measuring EEG-functional magnetic resonance imaging.

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

Abstract
Background A previous study (Roessner et al. 2007) found psychopathological evidence of an additive model of the comorbid group with Chronic Tic Disorders and Attention Deficit Hyperactivity Disorder (CTD+ADHD), which demanded clinical interventions aimed primarily at the factor ADHD. This 14-year follow-up study tested whether this childhood additive model can also be found in young adulthood and whether ADHD remains the most impairing factor. Methods 92 patients (22.8% girls) from Roessner et al. (2007) were re-investigated as young adults at the age of 24 years, broken down into four groups: CTD-only (n = 22), CTD+ADHD (n = 23), ADHD-only (n = 24), and controls (n = 23). The Adult Behavior Checklist (ABCL) was used as an equivalent parent-report instrument to the Child Behavior Checklist (CBCL) applied 14 years ago. Statistically, 2x2 factorial design was completed. Results From the point of view of parents, the factors CTD and ADHD in young adults contributed almost equally to psychopathological problems and showed many interactions, i.e. an interactive model was supported. In addition, the ADHD factor was no longer the leading problem for psychosocial impairment in the adult CTD+ADHD group. Conclusion The additive model of CTD+ADHD seems to exist no longer in young adults, nor may the childhood predominance of the factor ADHD in comorbid CTD+ADHD. Thus, treatment priority should be decided by clinicians on a case-by-case basis depending on the most impairing disorder of each patient.

Abstract
OBJECTIVE To examine in a community-based cohort: (1) the prevalence of chronic tic disorder (CTD) in children with attention-deficit/hyperactivity disorder (ADHD) compared with non-ADHD controls at ages 7 and 10; and (2) the additional psychiatric and functional burden of CTD in children with ADHD. METHODS Children aged 6-8 years with ADHD (n=179) and controls (n=212) were recruited through 43 Victorian schools using parent and teacher screening surveys (Conners 3 ADHD Index), followed by case confirmation (Diagnostic Interview Schedule for Children-IV (DISC-IV)). CTD was identified using the DISC-IV categories chronic motor tic disorder, chronic vocal tic disorder or Tourette syndrome at baseline and 36-month follow-up. Internalising and externalising disorders, social functioning, academic performance and quality of life were also measured. Tests of proportions and independent t-tests were used to compare the ADHD+CTD group with sex-matched ADHD alone children. RESULTS Compared with controls, children with ADHD were 4.1 (95% CI 1.1 to 14.1) times more likely to have CTD at age 7, and 5.9 (95% CI 1.6 to 17.9) times more likely at age 10. Children with ADHD+CTD experienced higher rates of internalising disorders and peer problems, and poorer quality of life than those with ADHD alone. CONCLUSIONS CTD prevalence is higher in children with ADHD compared with controls, and confers substantial additional psychiatric and functional burden. Clinicians need to consider CTD in both the initial assessment and ongoing management of children with ADHD, and address both the symptoms and the associated impairments.

Aripiprazole Selectively Reduces Motor Tics in a Young Animal Model for Tourette's Syndrome and Comorbid Attention Deficit and Hyperactivity Disorder. Front Neurol 2018; 9:59. [PMID: 29487562 PMCID: PMC5816975 DOI: 10.3389/fneur.2018.00059] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2017] [Accepted: 01/23/2018] [Indexed: 12/17/2022] Open
Abstract
Tourette’s syndrome (TS) is a neurodevelopmental disorder characterized primarily by motor and vocal tics. Comorbidities such as attention deficit and hyperactivity disorder (ADHD) are observed in over 50% of TS patients. We applied aripiprazole in a juvenile rat model that displays motor tics and hyperactivity. We additionally assessed the amount of ultrasonic vocalizations (USVs) as an indicator for the presence of vocal tics and evaluated the changes in the striatal neurometabolism using in vivo proton magnetic resonance spectroscopy (1H-MRS) at 11.7T. Thirty-one juvenile spontaneously hypertensive rats (SHRs) underwent bicuculline striatal microinjection and treatment with either aripiprazole or vehicle. Control groups were sham operated and sham injected. Behavior, USVs, and striatal neurochemical profile were analyzed at early, middle, and late adolescence (postnatal days 35 to 50). Bicuculline microinjections in the dorsolateral striatum induced motor tics in SHR juvenile rats. Acute aripiprazole administration selectively reduced both tic frequency and latency, whereas stereotypies, USVs, and hyperactivity remained unaltered. The striatal neurochemical profile was only moderately altered after tic-induction and was not affected by systemic drug treatment. When applied to a young rat model that provides high degrees of construct, face, and predictive validity for TS and comorbid ADHD, aripiprazole selectively reduces motor tics, revealing that tics and stereotypies are distinct phenomena in line with clinical treatment of patients. Finally, our 1H-MRS results suggest a critical revision of the striatal role in the hypothesized cortico-striatal dysregulation in TS pathophysiology.

Revisiting the co-existence of Attention-Deficit/Hyperactivity Disorder and Chronic Tic Disorder in childhood-The case of colour discrimination, sustained attention and interference control. PLoS One 2017; 12:e0178866. [PMID: 28594866 PMCID: PMC5464598 DOI: 10.1371/journal.pone.0178866] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2016] [Accepted: 05/19/2017] [Indexed: 01/28/2023] Open
Abstract
Objective Attention Deficit / Hyperactivity Disorder (ADHD) and Chronic Tic Disorder (CTD) are two common and frequently co-existing disorders, probably following an additive model. But this is not yet clear for the basic sensory function of colour processing sensitive to dopaminergic functioning in the retina and higher cognitive functions like attention and interference control. The latter two reflect important aspects for psychoeducation and behavioural treatment approaches. Methods Colour discrimination using the Farnsworth-Munsell 100-hue Test, sustained attention during the Frankfurt Attention Inventory (FAIR), and interference liability during Colour- and Counting-Stroop-Tests were assessed to further clarify the cognitive profile of the co-existence of ADHD and CTD. Altogether 69 children were classified into four groups: ADHD (N = 14), CTD (N = 20), ADHD+CTD (N = 20) and healthy Controls (N = 15) and compared in cognitive functioning in a 2×2-factorial statistical model. Results Difficulties with colour discrimination were associated with both ADHD and CTD factors following an additive model, but in ADHD these difficulties tended to be more pronounced on the blue-yellow axis. Attention problems were characteristic for ADHD but not CTD. Interference load was significant in both Colour- and Counting-Stroop-Tests and unrelated to colour discrimination. Compared to Controls, interference load in the Colour-Stroop was higher in pure ADHD and in pure CTD, but not in ADHD+CTD, following a sub-additive model. In contrast, interference load in the Counting-Stroop did not reveal ADHD or CTD effects. Conclusion The co-existence of ADHD and CTD is characterized by additive as well as sub-additive performance impairments, suggesting that their co-existence may show simple additive characteristics of both disorders or a more complex interaction, depending on demand. The equivocal findings on interference control may indicate limited validity of the Stroop-Paradigm for clinical assessments.

Abstract
Objective Both Tourette's disorder (TD) and attention-deficit/hyperactivity disorder (ADHD) have been related to abnormalities in glutamatergic neurochemistry in the fronto-striatal circuitry. TD and ADHD often co-occur and the neural underpinnings of this co-occurrence have been insufficiently investigated in prior studies. Method We used proton magnetic resonance spectroscopy (1H-MRS) in children between 8 and 12 years of age (TD n = 15, ADHD n = 39, TD + ADHD n = 29, and healthy controls n = 53) as an in vivo method of evaluating glutamate concentrations in the fronto-striatal circuit. Spectra were collected on a 3 Tesla Siemens scanner from two voxels in each participant: the anterior cingulate cortex (ACC) and the left dorsal striatum. LC-model was used to process spectra and generate glutamate concentrations in institutional units. A one-way analysis of variance was performed to determine significant effects of diagnostic group on glutamate concentrations. Results We did not find any group differences in glutamate concentrations in either the ACC (F(3132) = 0.97, p = 0.41) or striatum (F(3121) = 0.59, p = 0.62). Furthermore, variation in glutamate concentration in these regions was unrelated to age, sex, medication use, IQ, tic, or ADHD severity. Obsessive–compulsive (OC) symptoms were positively correlated with ACC glutamate concentration within the participants with TD (rho = 0.35, puncorrected = 0.02). Conclusion We found no evidence for glutamatergic neuropathology in TD or ADHD within the fronto-striatal circuits. However, the correlation of OC-symptoms with ACC glutamate concentrations suggests that altered glutamatergic transmission is involved in OC-symptoms within TD, but this needs further investigation. Large pediatric sample of ADHD and TD participants 3 Tesla proton MRS utilized to investigate fronto-striatal glutamate concentrations No differences in glutamate concentrations in the disorder groups compared with controls ACC glutamate concentrations associated with obsessive–compulsive symptoms in TD

Abstract
Tourette's syndrome (TS) is a neurodevelopmental disorder characterized by fluctuating motor and vocal tics, usually preceded by sensory premonitions, called premonitory urges. Besides tics, the vast majority—up to 90%—of TS patients suffer from psychiatric comorbidities, mainly attention deficit/hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD). The etiology of TS remains elusive. Genetics is believed to play an important role, but it is clear that other factors contribute to TS, possibly altering brain functioning and architecture during a sensitive phase of neural development. Clinical brain imaging and genetic studies have contributed to elucidate TS pathophysiology and disease mechanisms; however, TS disease etiology still is poorly understood. Findings from genetic studies led to the development of genetic animal models, but they poorly reflect the pathophysiology of TS. Addressing the role of neurotransmission, brain regions, and brain circuits in TS disease pathomechanisms is another focus area for preclinical TS model development. We are now in an interesting moment in time when numerous innovative animal models are continuously brought to the attention of the public. Due to the diverse and largely unknown etiology of TS, there is no single preclinical model featuring all different aspects of TS symptomatology. TS has been dissected into its key symptomst hat have been investigated separately, in line with the Research Domain Criteria concept. The different rationales used to develop the respective animal models are critically reviewed, to discuss the potential of the contribution of animal models to elucidate TS disease mechanisms.

Abstract
The aim of this study was to assess for the first time different dimensions of narcissistic self-regulation in a large cohort of adult patients with Gilles de la Tourette syndrome (GTS) (n=50). From preliminary studies it is suggested that narcissistic personality trait and disorder, respectively, are relatively uncommon and occur in only 6-10% of GTS patients. In this study we used the Narcissism Inventory (NI), a 163-items questionnaire that measures four different dimensions of narcissism. The main result was that the prevalence of narcissism strongly depends on the subtype of narcissism: while the vulnerable narcissism ("threatened self" and "hypochondriac self") was common, the "classic narcissistic self" (grandiose narcissism) was rare. From our data an association between comorbid depression and increased values of the "threatened self" and comorbid OCD with increased values of the "hypochondriac self" is suggested. Narcissism correlated positively with the personality domain neuroticism and had a significantly negative impact on patients' quality of life. Therefore it can be speculated that vulnerable narcissism is - among several others - one cause for depression in patients with GTS. These findings may open new psychotherapeutic perspectives in the treatment of depression in patients with GTS.

Abstract
Attention deficit hyperactivity disorder (ADHD) is characterized by severe and age-inappropriate levels of hyperactivity, impulsivity and inattention. ADHD is a heterogeneous disorder, and the majority of patients show comorbid or associated problems from other psychiatric disorders. Also, ADHD is associated with cognitive and motivational problems as well as resting-state abnormalities, associated with impaired brain activity in distinct neuronal networks. This needs to be considered in a multimodal treatment, of which neurofeedback (NF) may be a promising component. During NF, specific brain activity is fed-back using visual or auditory signals, allowing the participants to gain control over these otherwise unaware neuronal processes. NF may be used to directly improve underlying neuronal deficits, and/or to establish more general self-regulatory skills that may be used to compensate behavioral difficulties. The current manuscript describes pathophysiological characteristics of ADHD, heterogeneity of ADHD subtypes and gender differences, as well as frequently associated behavioral problems such as oppositional defiant/conduct or tic disorder. It is discussed how NF may be helpful as a treatment approach within these contexts.

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

Abstract
Objective: The study examines the role of obsessive-compulsive symptoms (OCS) as a part of the psychopathology of children with chronic tic disorders (CTD) and/or attention-deficit hyperactivity disorder (ADHD). Method: We assessed the psychopathology of four large patient groups without further psychiatric disorders: CTD (n = 112), CTD + ADHD (n = 82), ADHD (n = 129), and controls (n = 144)) by implementing the Child Behavior Checklist (CBCL). We compared the main effects for CTD and ADHD with and without including OCS as covariates. Results: Including OCS led to substantially different main effects for CTD on seven out of eight CBCL subscales. Slightly different main effects for ADHD were determined with respect to ADHD, mainly on the subscale withdrawn. Conclusions: OCS are closely related to CTD-associated psychopathology and – to a lesser extent, but nevertheless of importance in daily clinical practice – on ADHD-related symptoms. This information can be helpful in implementing more precise diagnostics and treatment in daily routine care.

Abstract
Gilles de la Tourette syndrome (GTS) holds a prime position as a disorder transgressing the brittle boundaries of neurology and psychiatry with an entangling web of motor and behavioral problems. With tics as the disorder's hallmark and myriads of related signs such as echo-, pali- and coprophenomena, paralleled by a broad neuropsychiatric spectrum of comorbidities encompassing attention deficit hyperactivity disorder, obsessive-compulsive disorder and self-injurious behavior and depression, GTS pathophysiology remains enigmatic. In this review, in the light of GTS phenomenology, we will focus on current theories of tic-emergence related to aberrant activity in the basal ganglia and abnormal basal ganglia-cortex interplay through cortico-striato-thalamocortical loops from an anatomical, neurophysiological and functional-neuroimaging perspective. We will attempt a holistic view to the countless major and minor drawbacks of the GTS brain and comment on future directions of neuroscientific research to elucidate this common and complex neuropsychiatric syndrome, which merits scientific understanding and social acceptance.

Abstract
OBJECTIVE This pilot study investigates the effects of habit reversal training in a German-speaking population of children and young adults with chronic tic disorders on comorbid symptoms and subjective interference. METHODS 16 children were treated using a manualized program. Comorbid-symptoms (ADHD, anxiety and OCD, depression) were assessed using parent and self-ratings. Additionally, the correlation of tic symptoms with comorbid symptoms at the beginning of the therapy was analyzed. RESULTS We obtained positive results in reducing comorbid symptoms during a primary treatment of tic symptoms. We further found a correlation of tic symptoms and comorbid symptoms especially in parent ratings. CONCLUSIONS These first findings show that a primary treatment of tics may be indicated in patients with comorbid symptoms, because a therapy of tic symptoms has also positive effects on comorbid symptoms.

Abstract
Seit dem Erscheinen unserer letzten Übersichtsarbeit zur «Therapie der Tic-Störungen» in der Zeitschrift für Kinder- und Jugendpsychiatrie wurden große Fortschritte auf diesem Gebiet erzielt. So wurden einzelne Bausteine auf dem Weg zur optimalen Behandlung konkretisiert, z. B. Veröffentlichung einheitlicher Kriterien zur Behandlungsindikation oder Entwicklung und Evaluierung eines detaillierten verhaltenstherapeutischen Manuals zum Habit-Reversal-Training. Daneben sind neue Therapiemöglichkeiten, wie das Medikament Aripiprazol oder die Tiefenhirnstimulation, erfolgreich implementiert worden. Auch wurde das Augenmerk viel stärker auf begleitende Störungen, wie ADHS und Zwangsstörungen, gerichtet, da diese in der Regel eine besonders starke Beeinträchtigung für die weitere Entwicklung des Kindes oder Jugendlichen darstellen. Dennoch bestehen weiterhin große Wissenslücken über die Effektivität der einzelnen Behandlungsmethoden, möglicher Kombinationsbehandlungen sowie deren direkter Vergleich untereinander. Daneben erschwert das Fehlen jeglicher Parameter zur Vorhersage der individuell sehr unterschiedlichen Entwicklung der Tics über die nächsten Monate und Jahre eine evidenzbasierte Therapieempfehlung und damit das Erlernen der Feinheiten bei der Behandlung von Tic-Störungen. Zusammengefasst ist noch immer eine große klinische Erfahrung für die Therapieentscheidungen beim einzelnen Patienten von großem Vorteil angesichts der enormen Bandbreite an individueller Tic-Symptomatik und Komorbidität gepaart mit den unvorhersehbaren Schwankungen im zeitlichen Verlauf.

Abstract
Attention deficit/hyperactivity disorder (ADHD) and tic disorders (TD) commonly co-occur. Clarifying the psychiatric comorbidities, executive functions and social adjustment difficulties in children and adolescents of ADHD with and without TD is informative to understand the developmental psychopathology and to identify their specific clinical needs. This matched case-control study compared three groups (n=40 each) of youths aged between 8 and 16 years: ADHD with co-occurring TD (ADHD+TD), ADHD without TD (ADHD-TD) and typically developing community controls. Both ADHD groups had more co-occurring oppositional defiant disorder than the control group, and the presence of TD was associated with more anxiety disorders. TD did not impose additional executive function impairments or social adjustment difficulties on ADHD. Interestingly, for youths with ADHD, the presence of TD was associated with less interpersonal difficulties at school, compared to those without TD. The potential various directions of effects from co-occurring TD should be carefully evaluated and investigated for youths with ADHD.

Abstract
Tourette's disorder (TD) in children and adolescents is frequently co-morbid with attention-deficit/hyperactivity disorder (ADHD). Dopamine-blockers are the first line treatment for TD, whereas dopamine-agonists, such as stimulants, are the gold-standard in the treatment of ADHD. These contrasting effects supported concerns about the risk that stimulants for treating ADHD may trigger or worsen co-morbid tics. Aripiprazole, a partial dopamine agonist, acts as an antagonist at dopamine D2 receptors in hyperdopaminergic conditions and displays agonist properties under hypodopaminergic conditions. The present study describes the use of aripiprazole (10.0 ± 4.8 mg/day) in a consecutive group of 28 patients with a primary diagnosis of TD and co-morbid ADHD, combined subtype. The Yale Global Tic Severity Scale (YGTSS) and the ADHD-Rating Scale (ADHD-RS-IV) were used as primary outcome measures and both significantly improved (p<0.001) after the treatment. Global measures of severity (Clinical Global Impressions-Severity) and of functional impairment (Children's Global Assessment Scale) also significantly improved during the treatment (p<0.001). At the YGTSS there was a reduction of 42.5%, in motor tics, of 47.9% in phonic tics (44.7% for the combined scores), and of 32.3% in tic impairment. Nineteen patients (67.9%) had a reduction of at least 50% of the YGTSS score (motor+phonic tics). The improvement at the ADHD-RS-IV score was 22.5%, 12 patients (42.8%) presented an improvement of 30%, but only 2 (7.1%) an improvement greater than 50%. Using a logistic regression model, a reduction of at least 30% in ADHD-RS-IV score was more likely to occur in the obsessive-compulsive disorder co-morbid group. Aripiprazole was well tolerated and none of the patients discontinued medication because of side effects. In summary, aripiprazole resulted in an effective treatment for TD, but it was only moderately effective on co-occurring ADHD symptomatology. Our preliminary data suggest that aripiprazole may represent a possible therapeutic option, among other possible monotherapies addressing both tics and ADHD.

Abstract
Background Structural changes have been found predominantly in the frontal cortex and in the striatum in children and adolescents with Gilles de la Tourette syndrome (GTS). The influence of comorbid symptomatology is unclear. Here we sought to address the question of gray matter abnormalities in GTS patients with co-morbid obsessive-compulsive disorder (OCD) and/or attention deficit hyperactivity disorder (ADHD) using voxel-based morphometry (VBM) in twenty-nine adult actually unmedicated GTS patients and twenty-five healthy control subjects. Results In GTS we detected a cluster of decreased gray matter volume in the left inferior frontal gyrus (IFG), but no regions demonstrating volume increases. By comparing subgroups of GTS with comorbid ADHD to the subgroup with comorbid OCD, we found a left-sided amygdalar volume increase. Conclusions From our results it is suggested that the left IFG may constitute a common underlying structural correlate of GTS with co-morbid OCD/ADHD. A volume reduction in this brain region that has been previously identified as a key region in OCD and was associated with the active inhibition of attentional processes may reflect the failure to control behavior. Amygdala volume increase is discussed on the background of a linkage of this structure with ADHD symptomatology. Correlations with clinical data revealed gray matter volume changes in specific brain areas that have been described in these conditions each.

Abstract
AIM The cognitive and psychiatric aspects of adult movement disorders are well established, but specific behavioural profiles for paediatric movement disorders have not been delineated. Knowledge of non-motor phenotypes may guide treatment and determine which symptoms are suggestive of a specific movement disorder and which indicate medication effects. METHOD The goal of this review is to outline the known cognitive and psychiatric symptoms associated with paediatric movement disorders. We used a systematic approach, via PubMed, and reviewed over 400 abstracts of studies of selected disorders, of which 88 papers reporting paediatric non-motor symptoms are summarized. RESULTS Obsessive-compulsive disorder was manifest in children with paediatric autoimmune neuropsychiatric disorders associated with streptococcal infections and Sydenham chorea. Children with opsoclonus-myoclonus syndrome had, for the most part, cognitive and behavioural problems, and attention-deficit-hyperactivity disorder was reported as a major comorbidity in Tourette syndrome, stereotypies, and restless legs syndrome. Symptoms of depression and anxiety were more frequent in individuals with idiopathic dystonia. Affective disorders were suggestive of Wilson disease. Cognitive decline was common in children with juvenile Huntington disease. A limitation of this review was the lack of systematic assessment in paediatric movement disorders for evaluation and uniform definitions. INTERPRETATION Although the literature in non-motor phenomena is still emerging, recognition of salient cognitive and psychiatric phenomena may facilitate management of paediatric movement disorders.

Abstract
The aim of the present study was to investigate the effect of both tic disorder (TD) and attention-deficit/hyperactivity disorder (ADHD) on attentional functions. N=96 children and adolescents participated in the study, including n=21 subjects with TD, n=23 subjects with ADHD, n=25 subjects with TD+ADHD, and n=27 controls. Attentional performance was tested based on four computerized attention tasks (sustained attention, divided attention, go/nogo and set shifting). The effect of TD as well as ADHD on attentional performance was tested using a 2 × 2 factorial approach. A diagnosis of TD had no negative impact on attentional functions but was associated with improved performance in the set shifting task. By contrast, regardless of a diagnosis of TD, subjects with ADHD were found to perform worse in the sustained attention, divided attention and go/nogo task. No interaction effect between the factors TD and ADHD was revealed for any of the attention measures. Our results add to findings from other areas of research, showing that in subjects with TD and ADHD, ADHD psychopathology is often the main source of impairment, whereas a diagnosis of TD has little or no impact on neuropsychological performance in most cases and even seems to be associated with adaptive mechanisms.

Abstract
To develop a European guideline on pharmacologic treatment of Tourette syndrome (TS) the available literature was thoroughly screened and extensively discussed by a working group of the European Society for the Study of Tourette syndrome (ESSTS). Although there are many more studies on pharmacotherapy of TS than on behavioral treatment options, only a limited number of studies meets rigorous quality criteria. Therefore, we have devised a two-stage approach. First, we present the highest level of evidence by reporting the findings of existing Cochrane reviews in this field. Subsequently, we provide the first comprehensive overview of all reports on pharmacological treatment options for TS through a MEDLINE, PubMed, and EMBASE search for all studies that document the effect of pharmacological treatment of TS and other tic disorders between 1970 and November 2010. We present a summary of the current consensus on pharmacological treatment options for TS in Europe to guide the clinician in daily practice. This summary is, however, rather a status quo of a clinically helpful but merely low evidence guideline, mainly driven by expert experience and opinion, since rigorous experimental studies are scarce.

Abstract
BACKGROUND Despite an increasing number of studies, findings of structural brain alterations in patients with Tourette syndrome are still inconsistent. Several confounders (comorbid conditions, medication, gender, age, IQ) might explain these discrepancies. In the present study, these confounders were excluded to identify differences in basal ganglia and corpus callosum size that can be ascribed more probably to Tourette syndrome per se. METHODS High-resolution T1-weighted structural magnetic resonance images of 49 boys with Tourette syndrome were compared with those of 42 healthy boys. The groups were matched for IQ and age (9 to 15 years). Boys with comorbid conditions and previous treatment were excluded. Volumes of gray and white matter, cerebrospinal fluid as well as the size of the basal ganglia, the thalamus, the corpus callosum and its subregions were estimated. RESULTS The left and right putamen and subregion 3 of the corpus callosum were larger in boys with Tourette syndrome than in healthy controls. No differences were found in volumes of caudate nucleus, globus pallidus or thalamus of each hemisphere or in total callosal size and its other subregions. CONCLUSIONS Bilateral enlargement of the putamen may reflect dopaminergic dysfunction or neuroimmunologic alterations (PANDAS) underlying Tourette syndrome. The larger callosal motor subregion 3 might be a consequence of daily tic activity. Previous divergent volumetric findings might be ascribed to confounding variables like comorbid conditions or medication, or to different imaging methods.

Abstract
Classification of tic disorders will be revised in the forthcoming edition of the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5). We do not support the suggestion to move tic disorders to "Anxiety and Obsessive-Compulsive Disorders", if the section "Disorders Usually First Diagnosed in Infancy, Childhood, or Adolescence" is not retained. Other than that, most proposed changes of the criteria for tic disorders contain a number of welcome improvements, e.g., the more unified definition of tics including the removal of the term "stereotyped" and the better capture of the temporal pattern of tics (e.g., removal of the maximum 3 months criterion for a tic-free period in chronic tic disorders). But, unfortunately there are some inconsistencies in detail, e.g., the unification of diagnostic criteria for tic disorders had not been consistently pursued in transient tic disorder. In sum, the proposed DSM-5 criteria could be seen as an important step forward particularly in clinical routine. However, continued research is needed to justify the existing and proposed classification of tic disorders as well as to better clarify what other changes should be made in the DSM-5 and beyond.

Abstract
We compared symptoms of generalized anxiety disorder (GAD) and separation anxiety disorder (SAD) in 5 groups of boys with neurobehavioral syndromes: attention-deficit/hyperactivity disorder (ADHD) plus autism spectrum disorder (ASD), ADHD plus chronic multiple tic disorder (CMTD), ASD only, ADHD only, and community Controls. Anxiety symptoms were assessed using parent and teacher versions of a DSM-IV-referenced rating scale. All three groups of boys with co-morbid ADHD evidenced more severe anxiety than Controls. Group differences in anxiety varied as a function of symptom, disorder, informant, and co-morbidity supporting the notion that co-morbid neurobehavioral syndromes differentially impact clinical features of co-occurring anxiety symptoms. Findings also suggest that GAD and SAD are phenomenologically unique, even in children with ASD. Implications for nosology are discussed.

Abstract
OBJECTIVE We report a case-series of seven patients with a medical history of at least two years of tic disorder treated with the partial dopamine agonist aripiprazole to illustrate its efficacy as a treatment alternative for motor and vocal tics in children and adolescents. METHOD A case series of five patients with Tourette Syndrome (TS) and two with chronic motor tic disorder (age range 8; 7-18; 1 year), the majority of whom had been refractory to treatment with other neuroleptics or had ceased treatment due to intolerable side effects, were treated for eight weeks with aripiprazole. Before and after treatment, parents rated the severity of motor and vocal tic symptoms on the Yale Tourette Syndrome Checklist. RESULTS Within eight weeks mean motor tic symptoms decreased by 66% and mean vocal tic symptoms decreased by 26%. Mean effective dosage was 14.3 mg/day (min. 5 mg, max. 30 mg). Symptoms of comorbid ADHD or Obsessive Compulsive Disorder were not significantly influenced. During medication only mild side effects were observed, e.g., abdominal pain, fatigue and increased emotional sensitivity. No patient dropped out of treatment due to side effects. CONCLUSIONS Aripiprazole may be an effective pharmacologic treatment alternative for individuals with chronic motor tic disorder and TS. It induces quick, significant and sustained effects with few generally mild and transient side effects, if anything. Its effectiveness, especially relative to comorbidities, should be verified in double-blind, placebo-controlled studies.

Abstract
In developmental psychopathology, differentiating between the coexistence and the clinical entity of two problem areas is of utmost importance. So far, logistic regression analysis has already provided helpful answers, as shown in studies on comorbidity of tic disorders. While the concept of bridging symptoms may be investigated adequately by both logistic regression and the network approach, the former (latent variable) seems to be of advantage with regard to the problems of multiple comorbidities and development.

Abstract
Coexistence of tics and attention-deficit/hyperactivity disorder (ADHD) has important clinical and scientific implications. Existing data on the co-occurrence of tic disorders, Tourette Syndrome (TS), and ADHD are largely derived from small-scale studies in selected samples and therefore heterogeneous. The Nordbaden project captures the complete outpatient claims data of more than 2.2 million persons, representing 82% of the regional population in 2003. Based upon the number of diagnosed cases of tic disorders, TS, and ADHD, we determined 12-months administrative prevalence rates as well as rates of co-occurrence. Both tic disorders and ADHD were diagnosed most often in the age group 7-12 years (any tic disorder: 0.8%; ADHD: 5.0%). With increasing age, the administrative prevalence difference in favor of males disappeared, with tic disorders being somewhat more frequently reported in females than males in the age groups above 30 years. The highest rate of ADHD co-occurring with tic disorders was found in adolescents (age 13-18 years, 15.1%). Tic disorders were observed in 2.3% of patients with ADHD. Administrative prevalence rates of tic disorders and TS were substantially lower compared to rates found in community-based epidemiological studies, suggesting that a large number of cases remain undetected and untreated under present conditions of routine outpatient care.

Abstract
OBJECTIVE To describe the clinical course of the Delta 9-tetrahydrocannabinol (Delta 9-THC) treatment of a boy with Gilles de la Tourette Syndrome (TS) and comorbid attention-deficit/hyperactivity disorder (ADHD) in relation to Delta 9-THC plasma levels and intracortical inhibition measured by transcranial magnetic stimulation. METHODS The clinical course and pharmacological and neurophysiological measures are reported in a 15-year-old boy with treatment refractory TS plus ADHD leading to severe physical and psychosocial impairment. RESULTS Administration of Delta 9-THC improved tics considerably without adverse effects, allowing parallel stimulant treatment of comorbid ADHD. Along with the Delta 9-THC treatment, intracortical inhibition was increased, reflected in the enhanced short-interval intracortical inhibition and the prolongation of the cortical silent period. CONCLUSIONS Our observation suggests that Delta 9-THC might be a successful alternative in patients with severe TS refractory to classic treatment. Particularly in the case of stimulant-induced exacerbation of tics, Delta 9-THC might enable successful treatment of comorbid ADHD. The enhancement of intracortical inhibition might be mediated by modulating release of several neurotransmitters including dopamine and gamma-aminobutyric acid. Further studies are needed to substantiate our findings.

Abstract
Morphometric findings in Tourette's syndrome (TS) are still inconsistent probably due to differences in analysis approaches as well as several confounders (coexisting psychiatric conditions, medication status, etc.). Our aim was to identify possible morphometric changes in a well-defined sample of drug-naïve boys with "pure" TS. High-resolution structural magnetic resonance images of 38 boys with TS were compared with those of 38 healthy boys matched for age and IQ using voxel-based morphometry (VBM). Coexisting psychiatric conditions and previous medication were excluded. The inclusion of 10- to 15-year-old boys minimized the well known compensatory changes due to tic suppression over many years. VBM analyses revealed no differences between the treatment naïve boys with "pure" TS and healthy controls. Brain morphology is not altered in boys with "pure" TS. Further studies should reveal whether previous findings might be ascribed to confounding factors like coexisting psychiatric conditions or long-term compensatory mechanisms due to voluntary tic suppression.

Abstract
OBJECTIVE This study examined the psychosocial and behavioral concomitants of anxiety in clinic-referred boys with attention-deficit/hyperactivity disorder (ADHD) with and without chronic multiple tic disorder (CMTD). METHOD ADHD boys with (n = 65) and without (n = 94) CMTD were evaluated with measures of psychiatric symptoms, mental health risk factors, and academic and social performance. RESULTS Boys with CMTD evidenced more severe anxiety and less social competence and were more likely to be living with only one biological parent than the ADHD Only group, but the magnitude of group differences was generally small. The severity of generalized anxiety, separation anxiety, social phobia, and obsessive-compulsive symptoms were uniquely associated with a different pattern of risk factors, and there was some evidence that these patterns differed for the two groups of boys. CONCLUSION Boys with CMTD had a relatively more severe and complex pattern of anxiety that was associated with different clinical features, all of which suggests that ADHD plus CMTD might better be conceptualized as a distinct clinical entity from ADHD Only. However, findings from the extant literature are mixed, and therefore this remains a topic for further study.

Abstract
OBJECTIVE Individuals with Tourette syndrome (TS) often display comorbid symptoms of attention-deficit hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD), as well as externalizing and internalizing behaviors. This study was aimed to examine the impacts of tic severity, ADHD symptoms, and OCD on internalizing (e.g., anxiety) and externalizing (e.g., aggression) psychopathology. METHODS Using linear regressions, we examined how tics, ADHD, and OCD symptoms predicted the externalization and internalization behaviors measured by the Child Behavior Checklist in a clinical sample of children and adolescents with TS. In addition, Child Behavior Checklist scales were compared among children with TS without ADHD, TS and ADHD, ADHD without TS, and unaffected control group. RESULTS In the TS group, externalizing behaviors were predicted by tic severity, inattention, and hyperactivity/impulsivity but not by OCD symptoms, whereas internalizing behaviors were predicted by inattention and OCD symptoms but not by tic severity or hyperactivity/impulsivity. Comparison among different clinical groups revealed main effects of TS and ADHD on both externalizing and internalizing behaviors. CONCLUSION These findings suggest that tics, ADHD, and OCD symptoms differentially explain the variance in externalizing and internalizing behavioral problems in individuals with TS. In addition, the data support the notion that TS is itself a risk factor for behavioral problems, mandating that children with TS even without ADHD and OCD still need to be assessed and treated for psychopathology.

Abstract
BACKGROUND Inhibitory deficits are often a matter of debate in the pathophysiology of Tourette syndrome (TS). Previous neuropsychological studies on behavioral inhibition revealed equivocal results. METHODS To overcome existing shortcomings (e.g. confounders like medication status, comorbid conditions) we compared medication naïve boys (10-14 years) suffering exclusively from TS with age, gender and IQ matched healthy controls using a highly demanding Go/Nogo task that controls for novelty effects. RESULTS The performance did not differ between boys with TS and healthy boys. CONCLUSION In TS normal response inhibition performance as measured by a Go/Nogo task can be assumed. However, there might be neurophysiological abnormalities in TS possibly related to compensatory mechanisms to control for tics. Hence, further studies combining neuropsychological and neurophysiological methods (e.g. electroencephalography, fMRI) using the same strictly controlled design along the whole range of development and tic severity are recommended.

Abstract
Preliminary findings suggest that color perception, particularly of blue-yellow stimuli, is impaired in attention-deficit/hyperactivity disorder (ADHD) as well as in chronic tic disorders (CTD). However, these findings have been not replicated and it is unclear what these deficits mean for the comorbidity of ADHD + CTD. Four groups (ADHD, CTD, ADHD + CTD, controls) of children with similar age, IQ and gender distribution were investigated with the Farnsworth-Munsell 100 Hue Test (FMT) and the Stroop-Color-Word Task using a factorial design. Color perception deficits, as indexed by the FMT, were found for both main factors (ADHD and CTD), but there were no interaction effects. A preponderance of deficits on the blue-yellow compared to the red-green axis was detected for ADHD. In the Stroop task only the 'pure' ADHD group showed impairments in interference control and other parameters of Stroop performance. No significant correlations between any FMT parameter and color naming in the Stroop task were found. Basic color perception deficits in both ADHD and CTD could be found. Beyond that, it could be shown that these deficits are additive in the case of comorbidity (ADHD + CTD). Performance deficits on the Stroop task were present only in the 'pure' ADHD group. Hence, the latter may be compensated in the comorbid group by good prefrontal capabilities of CTD. The influence of color perception deficits on Stroop task performance might be negligible.

Abstract
Although the coexistence of attention-deficit/hyperactivity disorder (ADHD) and tic disorder (TD) is common, the nature of association is yet not fully understood. Thus, the aim of the present study was to explore attentional dysfunction in children with pure ADHD compared to children with comorbid ADHD + TD. Three groups of 20 children each, aged 8-15 years with either ADHD, ADHD + chronic tic disorder or Tourette syndrome (ADHD + TD) and a healthy control group were compared in their performance on three computerized attention tasks. Tasks of sustained attention, selective attention and interference control were employed. In addition, parental ratings of ADHD symptom severity and behaviour problems were obtained. Both clinical groups were rated as equally inattentive, however, externalising symptoms were more severe in the ADHD group. Objective measures of attentional performance revealed differences between the groups: whereas the ADHD group was markedly impaired in sustaining attention and selective attention/inhibitory control, the ADHD + TD group only showed marginal deficits in selective attention/inhibitory control. Possible explanations for the superior performance of the comorbid group are discussed: In particular, the results may indicate that in some patients, the tic disorder produces behavioural symptoms of ADHD, but not the broad neurocognitive deficits that usually are associated with ADHD. Alternatively, compensatory neural mechanisms of TD patients may result in a better neuropsychological performance of comorbid patients relative to patients suffering from pure ADHD.

Abstract
BACKGROUND Tourette syndrome (TS) is a neurodevelopmental disorder with frequent comorbidity with Attention- deficit-Hyperactivity disorder (ADHD). The impact of this association is still a matter of debate. METHOD Using the TIC database containing 6,805 cases, the clinical differences were ascertained between subjects with and without ADHD. RESULTS The reported prevalence of ADHD in TS was 55%, within the range of many other reports. If the proband was diagnosed with ADHD, a family history of ADHD was much more likely. ADHD was associated with earlier diagnosis of TS and a much higher rate of anger control problems, sleep problems, specific learning disability, OCD, Oppositional-defiant disorder, mood disorder, social skill deficits, sexually inappropriate behaviour, and self-injurious behaviour. Subjects with seizures and with Developmental Coordination Disorder also had high rates of ADHD. Anxiety disorder, however, was not more frequent. Preliminary data suggest that most behavioural difficulties in ADHD are associated with the Combined or Hyperactive-Impulsive Subtypes of ADHD. Every large site (>200 cases) had a significantly increased rate of anger control problems in cases with ADHD. CONCLUSION Subjects with TS have high rates of ADHD and complex associations with other disorders. Clinically the findings confirm other research indicating the importance of ADHD in understanding the behavioural problems often associated with the diagnosis of TS. Additional ADHD comorbidity should be taken into account in diagnosis, management, and training.

Abstract
In daily clinical practice of child psychiatry tic disorders (TD) and attention-deficit/hyperactivity disorder (ADHD) as well as their co-existence are common and need careful evidence-based approaches in differential diagnostics and treatment choice. Hence, their relationship at different levels (e.g., psychopathology, neuropsychology, neurobiology, treatment) needs to be elucidated in more detail. The articles of this supplement deal with this subject. It is unclear if TD + ADHD represents an own clinical entity and which component (TD vs. ADHD) is most important in case of co-existence with respect to accompanying problems like emotional or cognitive disturbances. This editorial gives a short overview of the essential research topics concerning TD + ADHD and shows where (in this ECAP supplement and other literature) empirically based answers can be found. Probably, the identification of separate or common "endophenotypes" for TD-only, ADHD-only and for TD + ADHD would help to sort out the complexities and this supplement may nurture such a perspective of future research for a better understanding and treatment of youths with TD + ADHD and their families.

Abstract
OBJECTIVES To give an overview concerning the behavioral treatment approaches for Chronic Tic Disorder (CTD) and Attention-Deficit/Hyperactivity Disorder (ADHD) and to provide some suggestions for the behavioral treatment of children and adolescents with a combination of both disorders. RESULTS Pharmacotherapy plays an important role in the treatment of both ADHD and CTD. However, behavior therapy has also been proven to ameliorate the core symptoms of both disorders. The most prominent behavioral technique to reduce tics is habit reversal training. In ADHD behavioral interventions, especially parent training and behavioral interventions in preschool/school, are effective in reducing ADHD core symptoms and comorbid problems. In children and adolescents with ADHD plus CTD both ADHD and tic symptoms can be treated by behavioral interventions alone or in combination with pharmacotherapy. However, most of the published studies on behavioral interventions in children with ADHD or CTD do not give detailed information on comorbidity and many studies excluded patients with comorbid problems. CONCLUSIONS Clinical experience suggests that in CTD+ADHD success may be easier to achieve using behavioral treatment of ADHD first. Adherence to the habit reversal procedure to reduce tics in daily living is the most important problem in the behavioral treatment of tics especially in children with comorbid ADHD. Practical suggestions to overcome these difficulties are presented.

Abstract
OBJECTIVE In Chronic Tic Disorders (CTD) associated Attention Deficit Hyperactivity Disorder (ADHD) is very common. Hence, it is important to clarify how both conditions are related to cognitive dysfunctions in patients with CTD+ADHD comorbidity. Recent studies on neuropsychology revealed equivocal results, mostly due to methodological shortcomings like problems in sample composition. Thus better and more detailed information on this topic is needed to improve diagnostic and treatment approaches. METHOD Three tasks related to different domains of executive functions (the Matching Familiar Figures Test, the Stroop color-word interference task, and a computerized version of the Wisconsin Card Sorting Test) have been performed in two independent samples (altogether n = 138 children) both including four groups of children (CTD-only, CTD+ADHD, ADHD-only, healthy controls) matched for age and IQ. To specify the influence of either tics or ADHD-symptoms on executive functions and to answer the question of their interactive or additive relationship two-way analyses of variance (MANOVA) for the factors CTD (yes,-no) x ADHD (yes,no) were conducted. Eta squared was calculated to reveal the effect sizes for each factor. For a deeper understanding of group differences and to better enable the comparison with data in literature, additional analyses of variance (ANOVA) with posthoc testing were applied. RESULTS In summary, there was a main effect only for the factor ADHD reflected by decreased performance, while no main effect of the factor CTD could be found. Admittedly, the effects were not uniform in both samples. However, in all three tasks and both samples, uniformly no interaction between the main factors has been observed. CONCLUSIONS In cases of coexisting CTD+ADHD the factor ADHD shows the main negative impact on neuropsychological performance and this impact seems to be independent of any feature of the coexisting tics (additive model). This supports the notion to primarily treat the ADHD-symptoms in order to increase cognitive self regulatory abilities of these children. Contrarily, tics seem to have little impact on cognitive performance in most cases.
