ABSTRACT Two children with major depression experienced the emergence of motor and vocal tics after 2-3 weeks on imipramine at doses of 75-100 mg daily. The tics did not show any sign of subsiding for 9-10 days following the discontinuation of imipramine, but subsequently responded to treatment with haloperidol. Case 1 involved an 8-year-old child with depression, attention-deficit hyperactivity disorder (ADHD), other behavioral problems, and a history of a single febrile seizure. His family history was positive for tics, depression, anxiety, and seizures. He was found to have a toxic plasma level of the tricyclic antidepressant. Case 2 involved a 13-year-old child with depression, ADHD, behavioral problems, obsessive compulsive symptoms, intellectual deficit, developmental delays, grand mal seizures, and concomitant use of phenytoin. The child had previously developed tics while receiving methylphenidate. The family history was positive for tics, depression, obsessive compulsive symptoms, suicide, and alcohol abuse. The child had a subtherapeutic plasma level of the antidepressant. It is suggested that tricyclic antidepressants may precipitate tics consistent with the symptoms of Tourette's syndrome in genetically vulnerable children. Although this possibility has been suggested in the literature, these are the first two documented cases of this phenomenon. Speculating from these two cases, ADHD may be a risk factor for the appearance of imipramine-induced tic symptoms in depressed children.

Tourette syndrome (TS) is a neurobehavioral disorder that consists of simple and complex tics. This disorder can significantly affect a child's self-esteem and academic success. Although some believe that only adults are affected, this disorder occurs most frequently in early childhood and symptoms decrease with age. Diagnosis of this disorder can be difficult due to the high incidence of comorbidity of other psychiatric illnesses, such as attention-deficit hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), bipolar disease, and depression. Early recognition of the disorder allows positive interventions geared toward controlling tics and provides an outlet for tic release. Children and families who are affected by the disorder may attempt to hide the behaviors due to embarrassment of tics. The school nurse is instrumental in working with parents, staff, and other children to assure understanding of the disorder, provide coordination of care, and provide a safe outlet for the child to release the stress of tics during the school day.

Tourette syndrome (TS) is a chronic tic disorder that occurs in childhood. Children with TS may have multiple tic incidents during a day, even many times per minute. Such sudden, rapid and short utterings or movements may influence sufferers' ability to perform daily activities and present barriers to normal interaction with others. Anger, depression and low self-esteem are commonly seen in many children with TS. Awareness of TS is not great in Taiwan, and so many pediatric patients fail to obtain an early diagnosis and / or are mistreated or punished due to disorder-related behaviors. Such results in elevated physical, psychological and social stresses for sufferers. In this paper, we briefly introduce TS symptoms, diagnosis, classification, prognosis, co-morbidity, related psycho-social stresses, and common treatments. In order to facilitate the effective management of TS, we provide suggestion for patient families and schools as well as recommendations on how to interact effectively with others. We hope this article is helpful for healthcare workers, patients, families and schools to improve the recognition and management of TS.

Since the introduction of levodopa therapy and dopaminergic replacement therapy to abate symptoms of idiopathic Parkinson's disease, repetitive compulsive behaviors have been reported and are now considered to be drug-related response complications. As dopamine (DA) agonists are the licensed treatment in Restless Legs Syndrome (RLS), a survey was conducted to determine the extent to which patients with RLS present compulsive behaviors. The aim of this study was to investigate the relationship between DA agonists and the occurrence of motor or behavioral compulsions, stress, depression, and sleep disturbance in RLS patients. A questionnaire was mailed three times, at four-month intervals over a period of 8 months to all patients of the Quebec Memory and Motor Skills Disorders Clinic diagnosed with RLS. In addition to recording all medication information for RLS treatment, patients were assessed on the International Restless Legs Syndrome Study Group Rating Scale (IRLS), the Beck Depression Inventory-II (BDI-II), the Sleep Scale from the Medical Outcomes Study (MOS) and on a visual analog scale for current level of stress. A section pertaining to hobby, mania, and compulsion was also included. Analyses are based on 97 out of 151 patients (64.2%) with RLS who returned the three questionnaires. Twelve patients (12.4%) on stable DA agonist therapy (average dose 0.52+/-0.59 mg Pramipexole equivalent) developed a new compulsive behavioral repertoire. Eating (3 women, 1 man), buying food or clothes (2 women, 1 man), trichotillomania (1 woman, 1 man), and gambling (1man) were among the compulsions developed under DA treatment. In addition, two women presented new tic-like phenomena. In contrast to the RLS patients without compulsive behaviors (53 treated with DA agonist; 32 untreated), those with compulsive habits reported experiencing more stress, depression and sleep problems. Patients with RLS with mood and stress states may be at greater risk of developing compulsive behaviors while receiving standard dosage DA agonist treatment. These behaviors are clearly linked to short-term satisfaction and underline the role of dopaminergic mesolimbic stimulation in the reinforcement process of rewarding behavioral sequences.

Tourette syndrome (TS) is a neuropsychiatric disorder characterized by the presence of chronic, fluctuating motor and vocal (phonic) tics. The disorder is commonly associated with a variety of comorbidities including obsessive-compulsive disorder (OCD), attention deficit hyperactivity disorder (ADHD), school problems, anxiety, and depression. Therapeutically, if tics are causing psychosocial or physical problems, symptomatic medications are often prescribed, typically alpha-adrenergic agonists or dopamine antagonists. Recognizing that therapy is often ineffective and frequently associated with unacceptable side-effects, there is an ongoing effort to identify new tic-suppressing therapies. Several lines of evidence are presented that support the use of glutamate modulators in TS including glutamate's major role in cortico-striatal-thalamo-cortical circuits (CSTC), the recognized extensive interaction between glutamate and dopamine systems, results of familial genetic studies, and data from neurochemical analyses of postmortem brain samples. Since insufficient data is available to determine whether TS is definitively associated with a hyper- or hypo-glutamatergic state, potential treatment options using either glutamate antagonists or agonists are reviewed. Data from studies using these agents in the treatment of OCD are presented. If validated, modulation of the glutamate system could provide a valuable new pharmacological approach in the treatment of tics associated with Tourette syndrome.

The aims of this study were to examine a non-English (Hebrew) version of a scale that measures the premonitory urge in children suffering from tic disorder, as well as examine the correlations of the urge with demographic and clinical aspects of Tourette Syndrome. Forty children and adolescents, suffering from tics participated in this study. They were assessed with the Premonitory Urge for Tics Scale (PUTS); the Yale Global Tic Severity Scale (YGTSS); the Childhood Version of the Yale Brown Obsessive Compulsive Scale (CYBOCS); the ADHD Rating Scale IV (Conners) Scale; the Screen for Child Anxiety Related Emotional Disorders (SCARED); and the Child Depression Inventory (CDI). The mean PUTS score was 20.15 (SD = 5.89). For the entire sample the PUTS was found to be internally consistent at a = 0.79. Youths older than 10 years had higher consistency (a = 0.83) than youths younger than 10 (a = 0.69). Premonitory urge was not correlated with tic severity in the entire sample. In youths older than 10, as opposed to youths younger than 10, premonitory urge did correlate with obsessions, compulsions and depression, but not with anxiety or with ADHD. The premonitory urge can be measured reliably and the PUTS is a useful instrument for measuring this important phenomena. Premonitory urges seems to be related to obsessions, compulsions, and depression in older children and this may have implications for the developmental psychopatholgy of these symptoms.

Tourette syndrome is a neuropsychiatric disorder with the cardinal symptoms of motor and vocal tics. Often tics are accompanied by comorbidities such as obsessive-compulsive disorder, attention-deficit-hyperactivity disorder or depression. Research has mainly focused on the cortico-striato-thalamo circuit, but clinical symptoms and recent neuroimaging studies reporting altered resting network connectivity have suggested abnormalities in Tourette syndrome beyond the major motor circuits. We acquired diffusion-weighted data at 1.5T in nineteen adult patients fulfilling the DSM-IV-TR criteria for Tourette syndrome and in a healthy control group. Diffusion tensor imaging (DTI) analysis in our adult TS sample shows a decrease of FA and increase in radial diffusivity in the corticospinal tract. There are widespread changes (reduced FA and increased radial diffusivity) in the anterior and posterior limb of the internal capsule. Furthermore, it confirms prior findings of altered interhemispheric connectivity as indicated by a FA-decrease in the corpus callosum. In addition, our results indicate that TS is not restricted to motor pathways alone but affects association fibres such as the inferior fronto-occipitalis fascicle, the superior longitudinal fascicle and fascicle uncinatus as well. Tics are the hallmark of Tourette syndrome, so the involvement of the corticospinal tract fits in well with clinical symptoms. Cortical regions as well as limbic structures take part in the modulation of tics. Our findings of alterations in long association fibre tracts and the corpus callosum are a potential source for hindered interhemispheric and transhemispheric interaction. The change in radial diffusivity points toward a deficit in myelination as one pathophysiological factor in Tourette syndrome.

Quality of life (QoL) may be adversely affected by Tourette syndrome (TS). Although the core symptoms of this complex neurodevelopmental disorder are tics, patients often present with an array of behavioural difficulties, such as co-morbid obsessive compulsive disorder (OCD) or attention deficit hyperactivity disorder (ADHD). In this study we investigated whether young people with TS exhibited poorer QoL in comparison to healthy individuals and an epilepsy control group. We also analysed whether greater tic severity or co-morbid OCD and\or ADHD led to greater differences in perceived QoL. The Youth Quality of Life Instrument-Research Version (Edwards et al. in J Adolesc 25:275-286, 2002) was used to assess QoL and a range of clinical scales were administered to assess anxiety, depression and other behavioural symptoms. TS was associated with significant differences in aspects of QoL related to home and social activities, involving peer and family interactions. Patients with more severe tics reported a greater negative impact on QoL. Patients with TS and no associated diagnoses (pure TS) presented with lower QoL scores in the environment domain, poorer perceived QoL in general, and depressive features. Co-morbid OCD appeared to exert a greater impact on self and relationship QoL domains. The presence of both OCD and ADHD as co-morbidities led to more widespread problems. In conclusion, TS can be associated with poorer perceived QoL. Although social aspects of QoL may be more vulnerable to TS in general, co-morbid conditions make an important contribution in determining which aspects of QoL are most affected in the individual.

With the present review, we intend to highlight the importance of considering the age- and development-dependent occurrence of comorbidity in ADHD and to outline distinct trajectories of symptom progression with possible impact on course and outcome of ADHD. The review will focus on introducing the concepts of "developmental epidemiology" and "developmental comorbidity". Psychiatric and non-psychiatric age-dependent comorbidity can be seen in the majority of children, adolescents and adults with ADHD, resulting in a severe impairment of everyday life with considerable functional and psychosocial problems. Concerning the temporal order of occurrence, psychiatric conditions may be present before the appearance of first definite ADHD symptoms ("pre-comorbidity", such as temperament factors, sleep disturbance, autism spectrum disorders and atopic eczema). They may coincide with the time when ADHD symptoms reach a clinically significant level ("simultaneous comorbidity": enuresis, encopresis, developmental dyslexia). The majority of comorbidity, however, appears after the onset of ADHD in the course of disease ("post-comorbidity": tic disorder, depression and suicidality, anxiety disorders, obsessive compulsive disorder, bipolar disorder, conduct and substance use disorders, obesity and personality disorders). The aetio-pathophysiology of ADHD and its comorbid disorders and also the nature of comorbidity itself being highly heterogeneous, we additionally discuss possible models of comorbidity. In the future, longitudinal data on distinct patterns of symptom and comorbidity progression would help to refine disease classification systems, strengthen the power of future genetic studies and finally allow for more specific treatment strategies.

Tourette syndrome (TS) is a neurodevelopmental disorder involving tics, which is frequently accompanied by comorbid obsessive compulsive (OCD) or attention deficit hyperactivity disorder (ADHD). Individuals with TS often report poor quality of life (QoL) in comparison with the general population. This study investigated the clinical correlates of QoL in young people with TS using a self-report multidimensional QoL measure, and a range of clinical scales used to assess tic severity and the symptoms of anxiety, depression, OCD, ADHD and other emotional and behavioral symptoms. Symptoms of depression, OCD, and ADHD appeared to have a widespread negative impact on QoL, but poorer QoL was not associated with increased tic severity. Greater emotional and behavioral difficulties, including symptoms of OCD, were among the best predictors of poor QoL in young people with TS.
