Active clinical trials for "Tourette Syndrome"

The goal of the current study is to determine efficacy and safety of once-weekly aripiprazole in reducing Total Tic Severity (TTS) score in children and adolescents with Tourette's Disorder.

OBJECTIVES: I. Evaluate the safety and efficacy of the alpha-2 adrenergic agonist guanfacine in children and adolescents with Tourette syndrome or other chronic tic disorder, and attention deficit hyperactivity disorder.

Tourette syndrome is a childhood-onset neuropsychiatric disorder characterized by multiple motor and vocal tics that last for at least a year in duration. Currently, there exist several effective pharmacological treatments for childhood tics including alpha-2 agonist medications (guanfacine and clonidine) and neuroleptics (antipsychotic) medications. These medications, however, have significant side-effects and are only partially efficacy in treating tics. N-acetylcysteine (NAC) is a natural supplement that acts as an antioxidant and glutamate modulating agent. NAC has been used safely for decades in doses 20-40 times higher than in this trial as an antidote for acetaminophen overdose. The only side-effect commonly seen with NAC is nausea and this side-effect is seldom seen in the doses used in this trial. NAC has recently been demonstrated to be effective in a double-blind, placebo-controlled trial in adults with trichotillomania (chronic hair pulling). Hairpulling is hypothesized to be closely related to tics because these conditions (1) have similar clinical characteristics -- both groups typically experience urges before engaging in pulling or tics, (2) neuroimaging studies suggest they involve similar brain circuits -- the basal ganglia, (3) the same pharmacological treatments (neuroleptics) may be effective for both conditions and (4) they tend to be inherited together in families. In other trials NAC has evidence of some efficacy in treating diverse psychiatric conditions such as bipolar depression, schizophrenia and cocaine dependence. The investigators are conducting this trial to determine if NAC is an effective treatment for tics.

This is a single-arm open trial of Comprehensive Behavioral Intervention for Tics (CBIT) delivered to pediatric and adult patients with persistent tic disorders in their homes via videoconferencing (i.e., teleCBIT). All participants who enroll will receive teleCBIT.

The purpose of this study is to assess the feasibility of a trial on an oral orthotic for reducing tic severity in children ages 7-25 years with Tourette syndrome (TS) or Chronic Tic Disorder (CTD).

The purpose of this research is to examine the preliminary efficacy, feasibility, and acceptability of Voice over Internet Protocol delivered behavior therapy for Tourette Syndrome through in a randomized waitlist-controlled trial.

Gilles da la Tourette syndrome (TS)* is a common chronic neuropsychiatric disorder characterized by motor and vocal tics. In most adult patients, quality of life is significantly impaired. TS, therefore, is a cost-intensive disease (in Germany: mean total costs=€3404/year). Despite significant adverse effects, dopamine receptor antagonists were recommended as first choice treatment for many years. Although efficacy could be demonstrated only recently, today, behavioral therapy with face-to-face Comprehensive Behavioral Intervention for Tics (CBIT) (including psychoeducation, habit reversal training, function-based assessment and intervention, and relaxation training) is recommended as first line treatment for tics. In Germany, however, dissemination of CBIT is restricted due to a considerable lack of well-trained therapists. The aim of this study is to overcome this deficiency by creating a new and sophisticated internet-delivered CBIT (iCBIT) program. In addition, internet-delivered CBIT will shorten waiting time, will reach additional groups of patients and will be - once developed and established - highly cost-effective (about € 100 vs. € 1450 for face-to-face CBIT). Investigators want to perform a multicenter, randomized, controlled, observer-blind trial including 160 adult patients in order to demonstrate that 8 sessions (10 weeks) of iCBIT are superior to internet-delivered psychoeducation/relaxation in adult patients with TS. Both immediate (1 week after end of treatment) and long-term effects (after 3 and 6 months) will be evaluated.

Yigansan was used in Ming dynasty by Xue Kai as a remedy for restlessness and agitation in children. We expect that the total YGTSS scores of Yigansan-treated subjects will be significantly reduced compared to that of placebo-treated subjects.

In children with neurodevelopmental disorders, adolescence is usually associated with a reshaping of the clinical picture and symptomatology. Tourette syndrome (TS) is a paradigmal neurodevelopmental syndrome characterised by involuntary paroxysmal movements (motor tics) and vocalisation (vocal tics) often associated with various psychiatric disorders. The neuronal and cognitive mechanisms associated with TS symptoms improvement during adolescence, or the persistence in adulthood remains unknown, and this is what we aim to address in this study.

Specific Aim1: Using a paradigm of Transcranial Magnetic Stimulation called Continuous Theta Burst Stimulation (cTBS) to reduce tics in Tourette Syndrome subjects Hypothesis1: cTBS, compared to sham stimulation, will reduce tic severity by at least 25% as measured by the Yale Global Tic Severity Scale Specific Aim2: Using cTBS to further understand neural correlates of tic generation Hypothesis2: Functional MRI BOLD signal activation pattern will change after cTBS and this change will correlate with clinical improvement in tic severity
