Active clinical trials for "Tics"

Two-part study consisting of a double-blind, randomized, placebo-controlled, study at two target dose levels (Part 1) and an open-label, non-randomized study (Part 2) to determine the efficacy of ABX-1431 in treating adult patients with Tourette syndrome or Chronic Motor Tic Disorder as measured by the change from baseline in Total Tic Score of the Yale Global Tic Severity Scale (YGTSS-TTS) compared with placebo.

Tics are brief, sudden, repetitive movements and/or sounds that increase with stress, anxiety, transitions, or excitement. Tics occur most commonly in children and adolescents, with boys more frequently affected than girls The American Academy of Child and Adolescent Psychiatry states that tics affect up to 10 percent of children during their early school years. . The exact pathophysiologic mechanisms are unknown, but the disorders are likely to be due to disturbances of the cortico striatal- thalamo -circuitry. Risk factors for tic disorders include. Genetics: Tics tend to run in families, so there may be a genetic basis to these disorders. Sex: Men are more likely to be affected by tic disorders than women. They are divided into motor tics (e.g., blinking, shrugging shoulders, grimacing, or jerking) and vocal tics (e.g., throat clearing, sniffing, grunting) . Patients describe an inner urge or a local premonitory sensation, which is then relieved by performing the tic. The tic can be voluntarily suppressed for short periods of time. Tics increase with stress, anxiety, transitions, and excitement, and decrease with distraction. The American Academy of Child and Adolescent Psychiatry states that tics affect up to 10 percent of children during their early school years .The most notable tic disorder is Tourette syndrome, in which both physical and verbal tics occur in the same individual, often at the same time. Transient tic disorder also involves both types of tics, but they often occur individually . Tic disorders are classified into 3 categories : Transient tic disorders involve motor or vocal tics that last for more than 4 weeks but less than a year. Chronic tic disorders involve either motor tics or vocal tics (but not both) that last for more than a year. Tourette Syndrome, in which both physical and verbal tics occur in the same individual Conditions associated with tic disorders, especially in children with TS, include: anxiety, ADHD, depression ,autism ,spectrum disorder learning difficulties ,OCD speech and language difficulties, sleep difficulties other complications associated with tic disorders are related to the effect of the tics on self-esteem and self-image . Some research! has found that children with TS or any chronic tic disorder experience a lower quality of life and lower self-esteem than those without one of these conditions

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.

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.

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.

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, find them unacceptable, or cannot access them. Thus, it is essential that researchers continue to pursue novel treatment approaches that can also be easily disseminated to those in need. Initial pilot data suggest that a mindfulness-based intervention may be beneficial for adults with tic disorders. In the present study, the researchers aim to further develop this mindfulness-based intervention, adapt it to be delivered online and pilot test the intervention with a small group of participants. The data from this pilot test will inform a subsequent randomized controlled trial comparing online mindfulness-based tic reduction to online psychoeducation, relaxation, and supportive therapy. The specific aim is to determine the feasibility and acceptability of Online Mindfulness-based Tic Reduction in 6 adults with TS or PTD. The researchers hypothesize that Online Mindfulness-based Tic Reduction will be feasible and acceptable to adults with tic disorders as measured by participant satisfaction, qualitative participant feedback, home practice compliance, dropout, and adverse events.

The study will investigate the effects and the safety of a single-dose of ABX-1431 HCl on tics and other symptoms of Tourette Syndrome. During part 1 (periods 1 and 2) each patient will receive study drug once and placebo once. Patients who complete part 1 with adequate clinical safety will be offered the option to participate in part 2 (periods 3 and 4) and again willl receive study drug once and placebo once where, in contrast to part 1, administration will take place with a standard high fat meal.

The study aims to clarify the functional anatomy of key brain circuits associated with cognitive control in children and adolescents with chronic tic disorders (CTD) and to compare and contrast hypothesized mechanisms related to increased tic control associated with Habit Reversal Training, a behavioral treatment that been previously shown to be effective in treating CTD. We also seek to better understand the relationship between fMRI and quantitative EEG in relevant brain circuits with the hope of establishing EEG as a valid and cost-effective marker of treatment responsiveness. A total of 25 subjects will be randomized to 10 weeks of Habit Reversal Training (HRT), a behavioral treatment, and 25 to 10 weeks of minimal-contact waitlist. Treatment responders will be re-assessed at three months. Waitlist nonresponders will be provided with 10 weeks of HRT. Study assessments, including a neurocognitive battery and quantitative EEG will be administered at baseline, Wk 5, Wk 10, and 3-month follow-up. Neuroimaging (fMRI) will be conducted at baseline and Wk 10.
