Abstract
Cognitive flexibility in decision making depends on prefrontal cortical function and is used by individuals to adapt to environmental changes in circumstances. Cognitive flexibility can be measured in the laboratory using a variety of discrete, translational tasks, including those that involve reversal learning and/or set-shifting ability. Distinct components of flexible behavior rely upon overlapping brain circuits, including different prefrontal substructures that have separable impacts on decision making. Cognitive flexibility is impaired after chronic alcohol exposure, particularly during development when the brain undergoes rapid maturation. This review examines how cognitive flexibility, as indexed by reversal and set-shifting tasks, is impacted by chronic alcohol exposure in adulthood, adolescent, and prenatal periods in humans and animal models. We also discuss areas for future study, including mechanisms that may contribute to the persistence of cognitive deficits after developmental alcohol exposure and the compacting consequences from exposure across multiple critical periods.

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

Abstract
SummaryTourette syndrome is a complex neuropsychiatric disorder of juvenile onset, characterised by motor and phonic tics. It is associated with a number of comorbid psychiatric conditions and a reduced quality of life in the young person and with parenting stress, caregiver burden and psychopathology in the parents. The global prevalence (about 1%) is higher than previously thought, with a strong male preponderance. Evidence is emerging that Tourette syndrome is not a unified disorder; rather, it encompasses a number of subtypes, characterised by complexity of tics and the simultaneous presence of other behaviours or disorders. This article discusses the aetiology of the syndrome, and examines its clinical features and comorbid psychiatric conditions and psychopathologies. Assessment and diagnosis are also discussed. Psychoeducation is a cornerstone of management, augmented with behavioural and/or pharmacological treatments. Newer therapies, such as deep brain stimulation, offer tantalising possibilities, but further research is still needed.

Abstract
We present six patients with Gilles de la Tourette syndrome (TS) who are also deaf. TS has been observed previously, but rarely reported in deaf people, and to date, so called "unusual" phenomenology has been highlighted. TS occurs almost worldwide and in all cultures, and the clinical phenomenology is virtually identical. In our cohort of deaf patients (we suggest another culture) with TS, the phenomenology is the same as in hearing people, and as in all other cultures, with classic motor and vocal/phonic tics, as well as associated phenomena including echo-phenomena, pali-phenomena and rarer copro-phenomena. When "words" related to these phenomenon (e.g. echolalia, palilalia, coprolalia or mental coprolalia) are elicited in deaf people, they occur usually in British Sign Language (BSL): the more "basic" vocal/phonic tics such as throat clearing are the same phenomenologically as in hearing TS people. In our case series, there was a genetic predisposition to TS in all cases. We would argue that TS in deaf people is the same as TS in hearing people and in other cultures, highlighting the biological nature of the disorder.

Abstract
The fifth version of the Diagnostic and statistical manual of mental disorders (DSM-5) was released in May 2013 after 14 years of development and almost two decades after the last edition DSM-IV was published in 1994. We review the DSM journey with regards to Tourette Syndrome from the original publication of DSM 1 in 1952 till date. In terms of changes in DSM 5, the major shift has come in the placement of Tourette Syndrome under the 'Neurodevelopmental Disorders' alongside other disorders with a developmental origin. This review provides an overview of the changes in DSM-5 highlighting key points for clinical practice and research along with a snap shot of the current use of DSM as a classificatory system in different parts of the world and suggestions for improving the subtyping and the diagnostic confidence.

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

Abstract
Gilles de la Tourette syndrome (GTS) is characterised by multiple motor and one or more vocal/phonic tics. GTS was once thought to be rare, but many relatively recent studies suggest that the prevalence is about 1% of the worldwide community, apart from in Sub-Saharan Black Africa. Comorbidity and coexistent psychopathology are common, occurring in about 90% of clinical cohorts and individuals in the community. The most common comorbidities are attention deficit hyperactivity disorder, obsessive-compulsive behaviours, and disorder, and autistic spectrum disorders, while the most common coexisting psychopathologies are depression, anxiety and behavioural disorders such as oppositional defiant and conduct disorder. There has been an increasing amount of evidence to show that the quality of life in young people is reduced when compared with normative data or healthy control populations. It is widely accepted that most cases of GTS are inherited, but the genetic mechanisms appear much more complex than previously understood, as evidenced by many recent studies; indeed, there have been suggestions of 'general neurodevelopmental genes' which affect the brain development after which the 'specific GTS gene(s)' may further affect the phenotype. Other aetiopathogenetic suggestions have included environmental factors such as neuro-immunological factors, infections, prenatal and peri-natal difficulties and androgen influences. Few studies have addressed aetiology and phenotype, but initial results are exciting. The search for endophenotypes has followed subsequently. Intriguing neuroanatomical and brain circuitry abnormalities have now been suggested in GTS; the most evidence is for cortical thinning and a reduction in the size of the caudate nucleus. Thorough assessment is imperative and multidisciplinary management is the ideal. Treatment should be 'symptom targeted', and in mild cases, psycho-education and reassurance for the patient and the family may be sufficient. Behavioural treatments such as Comprehensive Behavioural Intervention for Tics including Habit Reversal Training have been shown to be significantly better than other behavioural/psychological treatments and 'placebo'. Medication is often necessary for moderately affected individuals. In more severe cases, medical treatment is not simple and referral to an expert may be advisable. In general, neuroleptics and clonidine or guanfacine are the medications of choice for the tics. Other treatments which may be needed for loud and severe phonic tics include botulinum toxin. In severe adult GTS patients who are refractory to medication and other therapies, deep brain stimulation looks promising.

Abstract
A working group of the European Society for the Study of Tourette Syndrome (ESSTS) has developed the first European assessment guidelines of Tourette Syndrome (TS). The available literature including national guidelines was thoroughly screened and extensively discussed in the expert group of ESSTS members. Detailed clinical assessment guidelines of tic disorders and their comorbidities in both children and adults are presented. Screening methods that might be helpful and necessary for specialists' differential diagnosis process are suggested in order to further analyse cognitive abilities, emotional functions and motor skills. Besides clinical interviews and physical examination, additional specific tools (questionnaires, checklists and neuropsychological tests) are recommended.

Abstract
OBJECTIVE Quality of life (QoL) has been shown to be lower in individuals with epilepsy than the general public. However, few studies have investigated the QoL of individuals with well-controlled epilepsy. This study investigated the effects of epilepsy on QoL in persons with treatment-responsive seizures, beyond factors directly related to the presence of seizures. METHODS Fifty young patients with controlled epilepsy and 102 healthy controls completed a generic, multidimensional, self-report QoL instrument, along with standardized scales assessing anxiety, depression, and other emotional or behavioral difficulties. RESULTS Young people with epilepsy reported increased anxiety (P=0.037) and more emotional and behavioral difficulties (P<0.001). Though there were was no difference between the groups in Total QoL score, treatment-responsive epilepsy was associated with lower QoL within the Self domain (P=0.016). CONCLUSIONS Epilepsy may exert a negative influence on QoL in relation to thoughts and feelings about the self in the context of complete seizure remission. Future research should investigate the therapeutic value of interventions targeting detrimental changes to self-perception in young people living with controlled epilepsy.

Abstract
BACKGROUND Eighteen patients with severe and refractory Tourette syndrome (TS) underwent bilateral thalamic deep brain stimulation (DBS). OBJECTIVE To assess the long-term outcome on tics, behavioral symptoms, and cognitive functions in the largest case series of thalamic DBS for TS to date. METHODS In this prospective cohort study, 15 of the original 18 patients were evaluated before and after surgery according to a standardized protocol that included both neuropsychiatric and neuropsychological assessments. RESULTS In addition to marked reduction in tic severity (p = 0.001), 24-month follow-up ratings showed improvement in obsessive-compulsive symptoms (p = 0.009), anxiety symptoms (p = 0.001), depressive symptoms (p = 0.001), and subjective perception of social functioning/quality of life (p = 0.002) in 15 of 18 patients. There were no substantial differences on measures of cognitive functions before and after DBS. CONCLUSIONS At 24-month follow-up, tic severity was improved in patients with intractable Tourette syndrome (TS) who underwent bilateral thalamic deep brain stimulation. Available data from 15 of 18 patients also showed that neuropsychiatric symptoms were improved and cognitive performances were not disadvantaged. Controlled studies on larger cohorts with blinded protocols are needed to verify that this procedure is effective and safe for selected patients with TS. LEVEL OF EVIDENCE This study provides class IV evidence that bilateral thalamic deep brain stimulation reduces global tic severity measured 24 months after implantation in patients with severe intractable Tourette syndrome.

Abstract
The overall international prevalence of Tourette syndrome (TS) is 1% in the majority of cultures of the world. Both TS and tics are certainly more obvious and may be more common in younger people. Moreover, TS is seen less frequently in some cultures. However, in all cultures where it has been reported, the phenomenology is similar, highlighting the biological underpinnings of the disorder. This article reviews the international prevalence, epidemiology, and clinical phenomenology of TS, from a cross-cultural perspective.

Abstract
OBJECTIVE Comorbidity between Tourette's syndrome (TS) and attention deficit hyperactivity disorder (ADHD) is high. In children, those with both TS+ADHD fare less well than those with TS-only on measures of both psychopathology and behaviour. The objective of this study was to document such measures in adult patients. METHOD Eighty adults with TS-only were compared to 64 with TS+ADHD using a clinical interview and standardised measures of depression, anxiety and obsessionality. RESULTS The two groups were no different on measures of TS severity. TS+ADHD patients had significantly more depression, anxiety, obsessive-compulsive behaviour and maladaptive behaviours than patients with TS-only. There were also significant differences in the incidence of copro- and echo-phenomena and family history of ADHD. CONCLUSION The finding of increased overall behavioural difficulties and psychopathology in adult patients with TS+ADHD when compared with TS-only is in agreement with previous findings in children with TS. Appropriate treatment of ADHD in TS patients during childhood may prevent many behavioural problems in adulthood.

Abstract
BACKGROUND A causal relationship of common streptococcal infections and childhood neuropsychiatric disorders has been postulated. OBJECTIVE To test the hypothesis of an increased rate of streptococcal infections preceding the onset of neuropsychiatric disorders. METHODS Case-control study of a large primary care database comparing the rate of possible streptococcal infections in patients aged 2-25 years with obsessive-compulsive disorder (OCD), Tourette syndrome (TS), and tics with that in controls matched for age, gender, and practice (20 per case). We also examined the influence of sociodemographic factors. RESULTS There was no overall increased risk of prior possible streptococcal infection in patients with a diagnosis of OCD, TS, or tics. Subgroup analysis showed that patients with OCD had a slightly higher risk than controls of having had possible streptococcal infections without prescription of antibiotics in the 2 years prior to the onset of OCD (odds ratio 2.59, 95% confidence interval 1.18, 5.69; p = 0.02). Cases with TS or tics were not more likely to come from more affluent or urban areas, but more cases lived in areas with a greater proportion of white population (p value for trend = 0.05). CONCLUSIONS The present study does not support a strong relationship between streptococcal infections and neuropsychiatric syndromes such as obsessive-compulsive disorder and Tourette syndrome. However, it is possible that a weak association (or a stronger association in a small susceptible subpopulation) was not detected due to nondifferential misclassification of exposure and limited statistical power. The data are consistent with previous reports of greater rates of diagnosis of Tourette syndrome or tics in white populations.

Abstract
Tourette syndrome is a neuropsychiatric syndrome characterized by motor and vocal tics with further co-morbidities, e.g. obsessive-compulsive disorder and attention deficit hyperactivity disorder. There is only a single prior case report in pregnancy in addition to a postal questionnaire study including 10 pregnancies. In a series of 11 pregnancies in patients assessed by the authors, there were no adverse effects on the pregnancy, although some obstetricians were unduly concerned. There was no consistent effect on the severity of the tics, although in some women there seemed to be a significant improvement during pregnancy.

Abstract
Gilles de la Tourette syndrome is a neurodevelopmental disorder consisting of multiple motor and one or more vocal/phonic tics. Tourette's syndrome is increasingly recognized as a common neuropsychiatric disorder usually diagnosed in early childhood, and comorbid neuropsychiatric disorders occur in approximately 90% of patients; the most common of these are attention deficit hyperactivity disorder and obsessive-compulsive disorder. Depression is also common, with a lifetime risk of 10% of patients. Moreover, a high prevalence of personality disorders has been reported in preliminary investigations on Tourette's syndrome populations. This paper provides an updated review of the literature on the multifaceted phenotype of Tourette's syndrome, with special attention to the behavioral problems and the relationship between Tourette's syndrome and comorbid neuropsychiatric conditions. The issue of whether Tourette's syndrome should still be considered as a unitary nosological entity is also addressed.

Abstract
Patients affected by epilepsy show a considerably higher incidence of depression compared with the general population. Since women are twice as likely as men to suffer from depression, female gender could be considered a major risk factor for developing this condition. Converging lines of evidence suggest that sex hormones, which are known to contribute to remodelling the hippocampus, play a pivotal role in both epilepsy and depression. In women, the role of sex hormone levels may be more important because of their physiological cyclic fluctuations. Oestrogens, more than other ovarian hormones, show an effect similar to antidepressant drugs by stimulating hippocampal synaptogenesis, thus exerting a protective role against seizures as well. This paper reviews the current knowledge on the neurobiological basis of depression in women with epilepsy. The emerging picture informs therapeutic strategies to improve the clinical management of this common comorbidity.

Abstract
BACKGROUND Gilles de la Tourette syndrome (GTS) is a chronic neuropsychiatric disorder which has a significant detrimental impact on the health-related quality of life (HR-QOL) of patients. However, no patient-reported HR-QOL measures have been developed for this population. OBJECTIVE The development and validation of a new scale for the quantitative assessment of HR-QOL in patients with GTS. METHODS In stage 1 (item generation), a pool of 40 potential scale items was generated based on interviews with 133 GTS outpatients, literature review, and consultation with experts. In stage 2 (scale development), these items were administered to a sample of 192 GTS outpatients. Standard statistical methods were used to develop a rating scale satisfying criteria for acceptability, reliability, and validity. In stage 3 (scale evaluation), the psychometric properties of the resulting scale were tested in a second sample of 136 subjects recruited through the UK-Tourette Syndrome Association. RESULTS Response data analysis and item reduction methods led to a final 27-item GTS-specific HR-QOL scale (GTS-QOL) with four subscales (psychological, physical, obsessional, and cognitive). The GTS-QOL demonstrated satisfactory scaling assumptions and acceptability; both internal consistency reliability and test-retest reliability were high (Cronbach alpha > or =0.8 and intraclass correlation coefficient > or =0.8); validity was supported by interscale correlations (range 0.5-0.7), confirmatory factor analysis, and correlation patterns with other rating scales and clinical variables. CONCLUSIONS The Gilles de la Tourette syndrome (GTS)-specific health-related quality of life (HR-QOL) scale (GTS-QOL) is proposed as a new disease-specific patient-reported scale for the measurement of HR-QOL in patients with GTS, taking into account the complexity of the clinical picture of GTS.

Abstract
Anti-basal ganglia antibodies (ABGAs) have been suggested to be a hallmark of autoimmunity in Gilles de la Tourette's syndrome (GTS), possibly related to prior exposure to streptococcal infection. In order to detect whether the presence of ABGAs was associated with subtle structural changes in GTS, whole-brain analysis using independent sets of T(1) and diffusion tensor imaging MRI-based methods were performed on 22 adults with GTS with (n = 9) and without (n = 13) detectable ABGAs in the serum. Voxel-based morphometry analysis failed to detect any significant difference in grey matter density between ABGA-positive and ABGA-negative groups in caudate nuclei, putamina, thalami and frontal lobes. These results suggest that ABGA synthesis is not related to structural changes in grey and white matter (detectable with these methods) within frontostriatal circuits.

Abstract
BACKGROUND There have been several reports of successful deep brain stimulation (DBS) for the treatment of severe Gilles de la Tourette syndrome (GTS). METHOD 18 cases of GTS who were resistant to at least 6 months of standard and innovative treatments, as well as to psychobehavioural techniques, underwent DBS. DBS was placed bilaterally in the centromedian-parafascicular (CM-Pfc) and ventralis oralis complex of the thalamus. Patients were evaluated after surgery, with immediate and formal assessments at least every 3 months, including "on-off" and "sham off" in the first nine patients. RESULTS All patients responded well to DBS, although to differing degrees. The duration of follow-up assessments ranged from 3 to 18 months. The comorbid symptoms of obsessive-compulsive behaviour, obsessive-compulsive disorder, self-injurious behaviours, anxiety and premonitory sensations decreased after treatment with DBS. There were no serious permanent adverse effects. CONCLUSIONS DBS is a useful and safe treatment for severe GTS. The results of ours and previous DBS reports suggest that the CM-Pfc and ventralis oralis complex of the thalamus may be a good DBS target for GTS.

Abstract
OBJECTIVES Gilles de la Tourette syndrome (GTS) is a chronic tic disorder associated with comorbid psychopathology, including obsessionality, affective instability and attention-deficit hyperactivity disorder. Evidence linking GTS with schizophrenia-like symptoms is limited and equivocal, despite a common putative substrate involving dopaminergic dysfunction within frontostriatal circuits. The aim of this study was to quantify the prevalence of schizotypal traits in GTS and to detail the relationship between schizotypy and comorbid psychopathology. MATERIALS AND METHODS A total of 102 subjects with GTS were evaluated using the Schizotypal Personality Questionnaire and standardized neurological and psychiatric rating scales. The predictive interrelation between schizotypy, tic-related symptoms and psychiatric comorbidities was investigated using correlation and multiple regression analyses. RESULTS In our clinical population, 15% of the subjects were diagnosed with the schizotypal personality disorder according to the DSM-IV criteria. The strongest predictors of schizotypy were obsessionality and anxiety ratings. The presence of multiple psychiatric comorbidities correlated positively with schizotypy scores. CONCLUSIONS Schizotypal traits are relatively common in patients with GTS, and reflect the presence of comorbid psychopathology, related to the anxiety spectrum. In particular, our preliminary results are consistent with a shared neurochemical substrate for the mechanisms underpinning tic expression, obsessionality and specific schizotypal traits.

Abstract
This is the first published case description in the current literature of the association of definite Gilles de la Tourette syndrome (GTS) and the Smith-Magenis syndrome (SMS), both confirmed by DSM-IV-TR criteria and molecular cytogenetic analysis, respectively. The co-occurrence of GTS, SMS and their common behavioural/neuropsychiatric abnormalities should warrant further genetic investigation of chromosome 17p11.2 deletion site as it may be a promising region for containing a gene(s) of aetiological importance in the development of the GTS phenotype. Alternatively, the co-occurrence may be due to the common endophenotypic mechanisms shared by these disorders, rather than being specific for GTS that could be explored using strategies of quantitative trait loci - endophenotype-based approach. Research into this genomic region may also benefit psychiatric genetic research in enhancing understanding of the biological and molecular underpinnings of common behavioural problems that are seen in both GTS and SMS. This would lead to advancement in neurobehavioural/neuropsychiatric genetics which will help in further explaining the broader perspective of gene-brain-behaviour interrelationships.

Abstract
Studies have shown that genetic factors are significant in predisposing individuals to obsessive-compulsive disorder (OCD). Family studies have demonstrated significantly higher rates of OCD in parents and siblings of OCD probands with an age-corrected morbid risk ranging from approximately 10% to 35% in first-degree relatives. Twin studies suggest that this familiality is, in part, due to genetic factors, and results from complex segregation analyses imply the existence of genes that have major effects on the transmission of OCD. However, not all cases of OCD seem to be familial. Furthermore, it appears that even in the familial form, there are clinical and genetic heterogeneities. Thus, future studies should either adjust the prevalence rates used in genetic analyses to account for nonfamilial cases or perform separate analyses of those families with a demonstrably familial form of OCD. Furthermore, in complex psychiatric disorders such as OCD, a single genetic locus may influence only a small part of phenotypic variance, and other genetic and environmental factors may interact in determining clinical phenotype. The implications of this finding on clinical and genetic heterogeneity in OCD are discussed.

Abstract
Gilles de la Tourette's syndrome (GTS) consists of multiple motor tics and one or more phonic tics. Psychopathology occurs in approximately 90% of GTS patients, with attention-deficit/hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD) being common. Depression is common, with a lifetime risk of 10% and a prevalence of between 1.8% and 8.9%. Depression and depressive symptoms are found to occur in 13% and 76% of GTS patients attending specialist clinics, respectively. In controlled studies embracing over 700 GTS patients, the patients were significantly more depressed than controls in all but one instance. In community and epidemiological studies, depression in GTS individuals was evident in two of five investigations. Clinical correlates of depression in people with GTS appear to be: tic severity and duration, the presence of echophenomena and coprophenomena, premonitory sensations, sleep disturbances, obsessive-compulsive behaviors/OCD, self-injurious behaviors, aggression, conduct disorder (CD) in childhood, and, possibly, ADHD. Depression in people with GTS has been shown to result in a lower quality of life, potentially leading to hospitalization and suicide. The etiology of depression appears to be multifactorial. Bipolar affective disorder (BAD) and GTS may be related in some individuals. However, it is noted that sample sizes in most of these studies were small, and it is unclear at the present time as to why BAD may be overrepresented among GTS patients.

Abstract
Amitriptyline, which is a noradrenaline reuptake and 5-HT reuptake inhibitor, has an established role in the management of chronic tension-type headaches. In a single-blind study, patients with chronic tension-type headache were randomized to either fluoxetine 20 mg (a selective 5-HT reuptake inhibitor) or desipramine 75 mg (a selective noradrenaline reuptake inhibitor) and followed for 12 weeks to compare the effectiveness of the two drugs in improving headache, and to assess whether pain control is related to changes in depression. Patients were evaluated at weekly intervals on an analog pain-rating scale and at 4-weekly intervals on the Montgomery and Asberg Depression Rating Scale (MADRS), the MOS general health status questionnaire (SF36), the Hospital Anxiety and Depression Scale (HADS), and a side effects checklist. Eighteen patients were randomized to take fluoxetine and 19 to take desipramine. Of the 25 patients who completed the trial, 12 were on fluoxetine and 13 were on desipramine. There was no significant difference between the two groups at baseline nor in change of pain; reduction in use of analgesic medication; nor change in the HADS, MADRS, or SF36 scores at 12 weeks, but 72% of patients who completed the study improved, and this improvement almost exactly mirrored the improvement on the MADRS. The results from this trial are compatible with the notion that the beneficial effect of antidepressants in chronic tension-type headache is indirect, mediated by an effect on depression, and not more,dependent on serotonin reuptake inhibition than noradrenaline reuptake inhibition.

Abstract
This study determined the prevalence of and factors associated with comorbid major depressive disorder (MDD) in patients with Gilles de la Tourette syndrome (GTS). How a simple self-report instrument, the Beck Depression Inventory (BDI), correlates with clinical assessment of comorbid MDD in this population was assessed. In a continuous sample of 114 adult patients with GTS, assessed clinically using the Diagnostic and Statistical Manual of Mental Disorders-IV criteria, 26 (23%) patients met criteria for MDD; more severe tics as measured with the Yale Global Tic Severity Scale, conduct disorder in childhood or higher age at the time of assessment were associated with MDD. The BDI score had a high negative predictive value for diagnosis of MDD, but a low positive predictive value. Using the BDI as a screening tool for comorbid MDD in patients with GTS is suggested.

Abstract
To investigate the immune-mediated response in TS, and its relationship with streptococcal infection, we measured serum levels of soluble intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1) and E-selectin in patients with TS, compared to healthy and diseased controls. Soluble VCAM-1 and sE-selectin were significantly elevated in children and adults with TS, and sVCAM-1 was higher among anti-basal ganglia antibodies (ABGA)-positive adults with TS. No correlation of adhesion molecule levels to clinical severity or anti-streptococcal antibodies was observed. Children with Sydenham's chorea and paediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS) showed an increased level of sICAM-1, but not sVCAM-1 and sE-selectin. These results provide initial evidence for a role of adhesion molecules and systemic inflammation in TS, and support the hypothesis of an ongoing immune-mediated process in this condition.

Abstract
Gilles de la Tourette's syndrome of chronic multiple motor and vocal tics is now acknowledged to be far more common than once thought, affecting up to 1% of schoolchildren with a wide range of severity. At the milder end of the spectrum the associated psychopathologies can in themselves impair social and educational functioning, in particular obsessive compulsive disorder and attention deficit hyperactivity disorder. Many patients with this condition are not being adequately served by health and education services in the UK. The epidemiology, clinical features, aetiological factors, and management of the syndrome are reviewed.

Abstract
OBJECTIVE A previous study showed no effect of 1Hz repetitive transcranial magnetic stimulation (rTMS) on tics in Gilles de la Tourette Syndrome (GTS). We modified the rTMS protocol in order to investigate some of the possible methodological reasons for the negative outcome in that study. METHODS In a single blinded placebo-controlled cross-over study in five GTS patients without obsessive compulsive disorder we probed whether longer trains (1800 stimuli) of 1 Hz pre-motor cortex rTMS at 80% of active motor threshold and application to both hemispheres can improve tics in GTS. This was measured with the Yale Global Tic severity rating scale, the MOVES self-rating scale and video analysis. RESULTS We found no significant effect of either left pre-motor cortex stimulation alone, or left pre-motor followed by right pre-motor cortex stimulation. CONCLUSIONS These results suggest that the rTMS protocol used in this study is not useful for the treatment of tics in GTS. SIGNIFICANCE rTMS protocols need to be modified substantially in order to explore their potential for the treatment of tics in GTS.

Abstract
The pathophysiology underlying the involuntary tics of Gilles de la Tourette syndrome (GTS) remains unknown. Here we used transcranial magnetic stimulation (TMS) to examine the excitability of two different inhibitory systems in the human motor cortex: short interval intracortical inhibition (SICI) and short interval afferent inhibition (SAI) in 10 healthy non-smoking controls and eight untreated non-smoking patients with GTS. Compared with the healthy control group, both SICI (measured at a range of conditioning intensities) and SAI were reduced in patients. This is consistent with the suggestion that reduced excitability of cortical inhibition is one factor that contributes to the difficulty that patients have in suppressing involuntary tics. In addition, the reduced SAI indicates that impaired intracortical inhibition may not be limited to the motor cortex but also involves circuits linking sensory input and motor output. A single dose of nicotine reduced tic severity as assessed by blind video scoring in the majority of patients. In addition, it abolished the difference between patients and controls in SICI and SAI. There was no effect of nicotine, and no difference between controls and patients in measures of motor or SICI threshold. This indicates that cholinergic input can modulate the efficiency of SICI and SAI differently in GTS and healthy controls.

Abstract
OBJECTIVES To localize genes influencing the susceptibility to Gilles de la Tourette syndrome (GTS) and associated chronic multiple tics (CMT). METHOD A single, large, multiple affected pedigree containing 35 subjects diagnosed with GTS and a further 14 with CMT was genotyped for markers spanning the autosomes. Linkage analysis was carried out using classical lod score analysis and model-free lod score analysis. All markers were subjected to two-point analysis, and markers producing a two-point result significant at P<0.005 were subjected to three-point analysis using adjacent markers. RESULTS The following markers produced at least one result significant at 0.005 using two-point analysis: D5S1981, D5S2050, D10S591, D10S189, D13S217, and D14S288. Three-point analysis with D5S2050 and D5S400 produced a lod of 2.9 with CMT. Three-point analysis of D10S591 and D10S189 produced lods of 1.9 with GTS and CMT. Three-point analysis of D13S217 and D13S171 produced a lod of 2.7 with GTS. No single haplotype appeared to account for the majority of cases within the pedigree. CONCLUSIONS It seems likely that more than one susceptibility allele is present in the pedigree. Although none of the three positive regions is conclusively implicated, it seems probable that at least one contains a susceptibility locus. We recommend that association-based studies be carried out in these three regions to produce further evidence for a localization and to carry out fine-mapping.

OBJECTIVE To investigate dopamine transporter binding in Gilles de la Tourette syndrome (GTS) with SPECT and [123I]FP-CIT. METHOD Ten neuroleptic naïve/free patients with GTS, and 10 age- and gender-matched normal volunteers were studied. Subjects were clinically evaluated. GTS severity and affective symptoms were measured and the presence of GTS-related behaviours were recorded. RESULTS The GTS group showed significantly higher binding in both caudate and putamen nuclei than the controls. No associations were found between striatal binding ratios and measures of affect or GTS-related behaviours. CONCLUSION Patients with GTS show higher striatal binding of FP-CIT to the striatum in comparison with age- and gender-matched control subjects, indicating that dopamine transporter abnormalities are involved in the pathophysiology of GTS. These abnormalities appear to be distributed across both caudate and putamen.

Abstract
BACKGROUND The classical neurological disorder after group A beta haemolytic streptococcal infection is Sydenham's chorea. Recently a tic disorder occurring after group A streptococcal infection has been described and termed PANDAS (paediatric autoimmune neuropsychiatric disorders associated with streptococcal infection). It is proposed that antibodies induced after group A streptococcal infection react with basal ganglia neurones in Sydenham's chorea and PANDAS. Anti-basal ganglia antibodies (ABGA) are present in most cases of acute Sydenham's chorea, but rarely in controls. OBJECTIVE To investigate the hypothesis that Tourette's syndrome may be associated with group A streptococcal infection and ABGA. METHODS 100 patients with Tourette's syndrome (DSM-IV-TR) were enrolled in a cross sectional study. Children with neurological disease (n = 50) and recent uncomplicated streptococcal infection (n = 40), adults with neurological disease (n = 50), and healthy adults (n = 50) were studied as controls. Recent group A streptococcal infection was defined using antistreptolysin O titre (ASOT). ABGA were detected using western immunoblotting and indirect immunofluorescence. RESULTS ASOT was raised in 64% of children with Tourette's syndrome compared with 15% of paediatric neurological disease controls (p < 0.0001), and in 68% of adults with Tourette's syndrome compared with 12% of adult neurological controls and 8% of adult healthy controls (p < 0.05). Western immunoblotting showed positive binding in 20% of children and 27% of adults with Tourette's syndrome, compared with 2-4% of control groups (p < 0.05). The most common basal ganglia binding was to a 60 kDa antigen, similar to the proposed antigen in Sydenham's chorea. Indirect immunofluorescence revealed autoantibody binding to basal ganglia neurones. Serological evidence of recent group A streptococcal infection, assessed by a raised ASOT, was detected in 91% (21/23) of Tourette's syndrome patients with positive ABGA compared with 57% (44/77) with negative ABGA (p < 0.01). CONCLUSIONS The results support a role of group A streptococcal infection and basal ganglia autoimmunity in a subgroup of patients with Tourette's syndrome and suggest a pathogenic similarity between Sydenham's chorea and some patients with Tourette's syndrome.

Abstract
Carisoprodol, a commonly prescribed muscle relaxant, has adverse effects on human performance and is gaining recognition as a factor in driver impairment and accident causation. Carisoprodol is a centrally acting skeletal muscle relaxant indicated for the relief of musculoskeletal pain. Carisoprodol and its major metabolite meprobamate have central nervous system (CNS) sedating effects similar to benzodiazepines or alcohol. Following the ingestion of carisoprodol or meprobamate symptoms such as drowsiness, confusion, poor balance, and coordination are well documented in drivers, all of which are detrimental to human performance and driving ability. Although identified as a drug capable of producing decreased human performance, the full extent of carisoprodol and meprobamate's involvement in motor vehicle accidents and effect on driving skills may not be fully appreciated. This is due in part to the common co-administration of other CNS depressants, hypnotics, or narcotic drugs and the lack of routine testing for carisoprodol and meprobamate in the human performance toxicology laboratory.

Abstract
In a single-blinded, placebo-controlled, crossover repetitive transcranial magnetic stimulation (rTMS) trial, 16 patients with Gilles de la Tourette syndrome (GTS) received in random sequence 1 Hz motor, premotor, and sham rTMS, which each consisted of two 20-minute rTMS sessions applied on 2 consecutive days. In the 12 patients who completed the trial, there was no significant improvement of symptoms after any of the rTMS conditions as assessed with the Motor tic, Obsessions and compulsions, Vocal tic Evaluation Survey.

Abstract
Gilles de la Tourette syndrome (GTS) is a genetic neuropsychiatric disorder, which is more common than previously thought. Ganser syndrome is an uncommon disorder, particularly in children. We present the first report of a young girl aged 7 who was diagnosed independently as having both GTS and Ganser syndrome and who was otherwise well and remained well and improved at follow-up 8 years later. This highlights how the clinicians must always be vigilant when atypical behaviours begin, especially when one diagnosis has already been given. There may well be treatment implications.

Abstract
OBJECTIVE Given the widely recognized genetic basis for Gilles de la Tourette syndrome (TS) and the suggestion that the putative TS gene(s) may be expressed as or associated with a variety of psychiatric illnesses, this study was undertaken to assess the prevalence of tics and TS in a psychiatric inpatient population. DESIGN Cross-sectional study. SETTING AND PATIENTS 200 consecutive adult patients who were admitted to the psychiatric wards of University College London Teaching Hospitals. OUTCOME MEASURES TS and related behaviours, as assessed by the comprehensive semi-structured National Hospital Interview Schedule. RESULTS None of the 200 patients had definite TS, but 2 were observed to have motor tics; 10 had a history of tics (present for less than a year), and 7 reported a family history of tics. Thus, 19 (9.5%) inpatients qualified for inclusion in a broadly defined TS diathesis. These rates are significantly lower than those reported in a similar community based epidemiological study of adolescents (p = 0.018). CONCLUSIONS Our findings do not support the theory that TS and related behaviours are over-represented among adult inpatients with psychiatric illnesses.

Abstract
The treatment of the Gilles de la Tourette syndrome has evolved from case reports, clinical experience and more recently blinded trials usually in small numbers of patients. We have reviewed the evidence available to clinicians. The oldest and still most widely prescribed drug, haloperidol, should now not be considered the first-line agent in children as other agents have superior adverse effects profiles. Symptomatic treatment should be targeted to the specific additional psychopathologies seen in the syndrome. For the treatment of tics, sulpiride, tiapride, possibly pimozide and in some cases clonidine may be considered first-line agents. Although a body of data supports pimozide, caution has to be exercised in relation to possible cardiac effects. Antidepressants and stimulants have an important place in the management of depression, obsessionality and attention deficit hyperactivity disorder. The latter also responds to clonidine making it a rational first choice where ADHD coexists with GTS. There are a multitude of other drugs advocated in the literature in addition to reports of neurosurgery and the novel use of immune modulation. Therapeutic trials for GTS are challenging. However, further data from blinded trials are required before many of these treatments can be considered to be mainstream treatment options.

Abstract
OBJECTIVE This is the first study to investigate the Quality of Life (QOL) of patients with Gilles de la Tourette's Syndrome (GTS). METHOD One hundred and three out-patients with GTS completed a semi-structured interview and 90 of these completed questionnaires screening for depression, anxiety and obsessive-compulsive behaviour. QOL was measured with the SF-36 and the Quality of Life Assessment Schedule (QOLAS). RESULTS Patients with GTS showed significantly worse QOL than a general population sample. They had better QOL than patients with intractable epilepsy as measured by the QOLAS, although the SF-36 showed significant differences on the subscales Role Limitation due to physical problems and Social Functioning only. Factors influencing QOL domains were employment status, tic severity, obsessive-compulsive behaviour, anxiety and depression. CONCLUSION QOL is impaired in patients with GTS. Measurement of QOL could be used alongside conventional measurements to assess benefit of treatment. We recommend the QOLAS and SF-36 be used.
