Active clinical trials for "Tic Disorders"

Expert reviews and practice parameter papers recommend behavior therapy as a first-line intervention for youth with chronic tic disorders (CTDs) with mild-to-moderate tic severity. Although behavior therapies like the Comprehensive Behavioral Intervention for Tics (CBIT) are efficacious in reducing tic symptom severity, only 50% of individuals exhibit a positive treatment response. Thus, there is a clear need to identify strategies to improve treatment response and/or accelerate therapeutic gains . The primary ingredient of CBIT is habit reversal training (HRT), which utilizes both extinction and associative learning. Psychosocial treatments relying on these learning mechanisms have demonstrated an enhanced and/or expedited therapeutic benefit when augmented with d-cycloserine (DCS). This feasibility study will examine the incremental efficacy of HRT+DCS over HRT+placebo for tics targeted with HRT. Eligibility criteria will parallel the child CBIT trial for generalizability and comparability, with the addition of DCS contraindications as exclusionary criteria. Parents and youth will complete a battery of clinical assessments to ascertain tic symptoms severity and co-occurring psychiatric conditions. Afterwards, participants will be randomly assigned to receive either HRT+DCS or HRT+placebo. Instead of a full course of HRT (8 sessions over 10 weeks), a more efficient Quick-Win/Fast-Fail trial design will be used that includes a truncated HRT protocol to provide results in a more timely fashion. As a result of this trial design, the primary outcome of this study will focus on the reduction of bothersome tic severity for those targeted in treatment rather than global severity reductions.

Tics are brief repetitive movements or vocalizations. Gilles de la Tourette's syndrome (TS) is a disorder characterized by recurrent motor and vocal tics. Tourette syndrome and tic disorders affect up to 8% of children. Peak severity of tic disorders occurs between the ages of 8 to 12 years, therefore during childhood and adolescence the most significant impacts are felt. The quality of life of young people with tics is lower than their peers' and tic severity predicts lower quality of life. Studies have also shown negative social perception toward children with tics. Approximately 50% of patients with Tourette syndrome will have other diagnoses including attention deficit hyperactivity disorder (ADHD), obsessive compulsive disorder, anxiety and depression. Studies have shown improvements in ADHD with physical activity. ADHD and tic disorders are thought to involve the same areas of the brain; thus it is possible that tics might also improve with physical activity. However, no studies to date have examined this. The investigators predict that by implementing a motivational physical activity program, in conjunction with physical activity counseling, the investigators will be able to increase levels of physical activity in children with tics and Tourette syndrome, with a positive impact on tic severity.

Bacteria carry substances on their surface called antigens. When antigens come into contact with the right kinds of cells in the body an immune reaction is caused. This reaction is often the symptoms of sickness that a patient feels. In order for the body to fight off the attack of antigens, it creates substances called antibodies. Antibodies counter the action of antigens and make the bacteria harmless. However, the immune system must learn how to make the right antibodies for the right antigens. Sometimes the body creates antibodies that confuse normal tissues as foreign and attack them. This is called an autoimmune reaction and sometimes occurs when the body is exposed to certain bacteria. One bacteria known for causing autoimmune reactions is Group A beta-hemolytic Streptococcus (GABHS). This bacteria often causes throat infections commonly known as "strep throat". Some researchers believe that the autoimmune reaction associated with strep throat infections may cause neuropsychiatric disorders, like obsessive-compulsive disorder and/or tic disorder in children. As a result, each time a child with one of these disorders experiences an infection with GABHS his/her symptoms can reoccur or worsen. Researchers believe that by giving patients a certain antibiotic, they can prevent GABHS infection and thus prevent the return of symptoms. This study is designed to test the effectiveness of the antibiotic Amoxicillin for the treatment of Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections (PANDAS). Patients will receive Amoxicillin for six weeks and placebos "inactive sugar pills" for six weeks in order to see if the medication is truly working. Effectiveness of the treatment will be based on the presence or absence of symptoms. If at the end of the study Amoxicillin is proven to be effective treatment for PANDAS patients may be offered the opportunity to continue taking the medication for an additional six months.

Tourette Syndrome (TS) and Persistent Tic Disorder (PTD) are chronic and potentially disabling neurobiological conditions. Although a range of pharmacological and psychosocial treatments exists, a significant number of individuals either do not respond to the current treatments or find them unacceptable. Thus, it is essential that researchers continue to develop and test novel treatment approaches. In this randomized controlled trial the investigators will compare two different online group-based interventions for tics: a mindfulness-based program (Mindfulness-based Intervention for Tics (MBIT), and a psychoeducational and supportive therapy program (Tic Information and Coping Strategies (TICS)). The purpose of this study is to determine which intervention is more helpful for adults with a tic disorder.

Aversive sensory phenomena such as premonitory urges play a central role in the behavioral treatment model of tics. Extinction learning and extinction recall are learning processes implicated within this model, but are still understudied for individuals with Tourette syndrome (TS). This study examines extinction learning and extinction recall in adults with TS using an experimental task. This study will also explore the relationship between extinction processes (i.e., extinction learning and extinction recall) and treatment outcomes with behavior therapy. Findings from this investigation will be used to update the behavioral treatment model, which serves as the basis for evidence-based behavioral interventions.

This is a multicentre, randomized, double-blind, placebo controlled, parallel-group, phase IIIb trial. Patients (≥18 years) with chronic tic disorders and Tourette syndrome will be recruited. The objective of the trial is to demonstrate that treatment with the cannabis extract nabiximols is superior to placebo in reducing tics and comorbidities in patients with Tourette syndrome and chronic tic disorders.

The aim of this study is to train patients with tic disorders to control activity in a region of their brain that has been associated with the urge to tic. Patients will be given direct feedback regarding activity in this brain area while they are undergoing functional magnetic resonance imaging (fMRI) scanning, and will try to learn to control activity in the region during these feedback sessions. In separate sessions, patients will be given sham feedback based on the brain patterns of a prior subject rather than their own brain patterns. Our primary hypothesis is that the biofeedback training will reduce their tic symptoms more than the sham feedback.

This is a clinical study of a cognitive-behavioral therapy known as anger control training in adolescents with Tourette Syndrome and explosive, disruptive behavior. ACT is compared to treatment as usual (TAU) in a randomized clinical trial.

This pilot study aims evaluate the feasibility and initial efficacy of behavior therapy augmented by d-cycloserine (DCS) compared to behavior therapy augmented by placebo. After an initial assessment to determine eligibility, youth with TD will be randomly assigned to receive four sessions of behavior therapy augmented by either DCS or placebo. D-cycloserine is an FDA-approved antibiotic medication that has been shown to enhance extinction learning in several studies. The investigators' proof-of-concept work has found that a single session of DCS-augmented behavior therapy reduced the severity of tics targeted in treatment on the Hopkins Motor/Vocal Tic Scale (HM/VTS) compared to placebo-augmented behavior therapy. This highlights the exciting potential of combining DCS with behavior therapy to improve reductions in tic severity. However, prior to a large-scale clinical trial, it is essential to determine the feasibility and efficacy of augmenting behavior therapy with DCS over multiple treatment sessions.
