Filter by:Analysis of data from the recently completed NIH Child Comprehensive Behavioral Intervention for Tics (CBIT) study found a manualized behavioral treatment approach strongly superior to psychoeducation/supportive therapy for reducing tic severity in 9-16 year-old youths with TS or other Chronic Tic Disorders. Buoyed by the success of the NIH study, the research group now seeks to extend and disseminate the CBIT treatment through the systematic adaptation of the CBIT protocol for use across a broader range of ages and treatment settings. The goal of the this project is to develop a downward extension of the CBIT therapist guide and parent workbook for use in 4-8 year old children with chronic tics. The revised CBIT-JR manual/workbook will be pilot tested in five children at each of the three study sites (UCLA, UWM, Weill Cornell) in order to provide initial data regarding treatment feasibility and acceptability as well as our ability to implement the new intervention, along with relevant quality control procedures, consistently across sites. These pilot data will then be used to seek R01 support for a larger controlled multisite trial examining the efficacy of CBIT-JR. Although arguably more complex than a single-site design, we have opted for a multsite study in order: 1) to take advantage of the established productive collaborative relationship and collective expertise in childhood tic disorders and psychosocial treatment development across our three sites, 2) to collect the proposed feasibility data in a much shorter period of time than otherwise possible, and as noted above 3) to demonstrate the cross-site portability of the treatment - which will be necessary if we are to obtain subsequent funding for a larger-scale efficacy trial.
The main objective of this project is to evaluate the efficacy of subthalamic nucleus deep brain stimulation (STN DBS) in treating motor and phonic tics in medically refractory Tourette's syndrome (TS). Secondary objectives are to individuate and standardize the best electrical parameters for STN stimulation in TS, to evaluate the efficacy and safety on non-motor TS features, such as behavioral abnormalities and psychiatric disorders, during chronic STN stimulation, to correlate the improvement of TS motor and non-motor symptoms to the modification in brain activity recorded by PET study and to explore the pathophysiology of TS, and to evaluate the safety of STN DBS in TS patients.
The purpose of this study is to examine how the brain and environment interact to influence children's ability to suppress tics using a medical technology called Transcranial Magnetic Stimulation (TMS).
Tourette's Syndrome is a neurological disease characterized by motor and vocal tics. It has been hypothesized that abnormal interactions of dopamine with its receptors may cause the tics. The purpose of this study is to test the hypothesis that a drug (ecopipam) that selectively blocks dopamine D1/D5 receptors can reduce the frequency and severity of the tics.
Tourette's Syndrome is a neurological disease characterized by verbal and motor tics. The currently available drug treatments are considered to be inadequate. This clinical trial is designed to test if ecopipam is effective for the treatment of Tourette's Syndrome in adults.
Background: - Previous studies have given researchers information on how the brain controls movement, how people learn to make fine, skilled movements, and why some people have movement disorders. However, further research is needed to learn more about the causes of most movement disorders, such as Parkinson's disease. - By using small, specialized studies to evaluate people with movement disorders and compare them with healthy volunteers, researchers hope to learn more about the changes in the brain and possible causes of movement disorders. Objectives: - To better understand how the brain controls movement. - To learn more about movement disorders. - To train movement disorder specialists. Eligibility: - Individuals 18 years of age or older who have had a movement disorder diagnosed by a neurologist and are able to participate based on the specific requirements of the small study. - Healthy volunteers 18 years of age or older. Design: - Participants will have a screening visit with medical history, physical examination, and questionnaire to determine eligibility. Eligible participants will give consent to participate in up to seven additional outpatient visits for study procedures. The number of sessions and the procedures needed for participation depend on specific symptoms. - Participants must avoid drinking alcohol or caffeinated drinks (sodas, coffee, and tea) for at least 2 days (48 hours) before each session. - Potential studies may include magnetic resonance imaging (MRI) scans, functional MRI scans, electroencephalography, magnetoencephalography, transcranial magnetic stimulation, nerve and sensory stimulation, or movement and mental tasks during any of the above procedures. - This study does not provide treatment for movement disorders. Participants will not have to stop any treatment in order to participate.
This study will investigate how the sensitivity to touch and smell in patients with Tourette syndrome (TS) may differ from that of people without TS. TS is a neurological disorder that causes people to have uncontrolled movements called "tics." A tic can also be vocal, like a cough or bark or string of bad words. The tic is preceded by a "premonitory urge" that may feel like an itch or pressure that builds until the tic occurs. To some patients, the tic feels like a response to an involuntary sensation. In patients with TS, sensory information may be processed differently than it is in people without TS. This study will compare how strong a sensation feels in TS patients and healthy volunteers. It will also look for muscle activity that may be responsible for the feelings in the area of the tic. Healthy normal volunteers and people with Tourette syndrome, 18 to 65 years of age, may be eligible for this study. Candidates are screened with a medical history and brief physical and neurological examinations. TS patients complete a questionnaire about their tics and are interviewed by a psychiatrist. Women who can become pregnant will have a urine pregnancy test prior to any other procedures. Pregnant women cannot participate. All participants undergo sensory testing for touch and smell. They are asked to distinguish between a scented and scentless object and rate how strongly they feel the scent. Later, with their eyes closed, they are asked to tell whether or not they are being touched, and to rate how intensely they felt the touch. In addition to the sensory testing, TS patients, but not normal volunteers, undergo electromyography (EMG), a test that measures the electrical activity of muscles. For surface EMG, small metal disks called electrodes are filled with a conductive gel and taped to the skin. Wire EMG involves inserting a wire into a muscle using a needle. All patients have surface EMG and those who consent to it will also have wire EMG.
The purpose of this study is to determine if Abilify will reduce tics (repetitive, uncontrollable movements or vocalizations) in children and adolescents ages 7-18 with Tourette's Disorder (TD) or a chronic motor tic disorder (either repetitive, uncontrollable movements or vocalizations).
Tourette's syndrome is a disabling neuropsychiatric disorder with major psychosocial consequences in some patients. The pathophysiology is still unknown. Some data suggest an dysfunction of limbic circuits in basal ganglia. The aim of this study is to evaluate the effect of high frequency stimulation of the internal part of the globus pallidus and/or parafascicular-median centre of the thalamus, two structures implicated in the limbic circuit, in patients with severe Tourette's syndrome.
This study will investigate the brain areas that are activated by vocal and motor tics in patients with Tourette's syndrome and other tic disorders. Tics are involuntary repetitive movements similar to voluntary movements. They may be simple, involving only a few muscles or simple sounds, or complex, involving several groups of muscles in orchestrated bouts. This study will involve only simple motor tics, such as eye blinking, nose wrinkling, facial grimacing and abdominal tensing, and simple vocal tics, such as throat clearing, sniffing and snorting. Healthy normal volunteers and patients between 14 and 65 years of age with simple motor or vocal tics may be eligible for this study. Participants will have a brief medical history and physical examination and magnetic resonance imaging (MRI) of the brain. MRI uses a magnetic field and radio waves to produce images. For the procedure, the subject lies on a table that is moved into a cylindrical chamber containing a strong magnet. Earplugs are worn to muffle the loud thumping sounds made by electrical switching of the radio frequency circuits and protect against temporary hearing impairment. During the scan, normal volunteers will be asked to make simple movements or sounds designed to imitate tics, such as raising eyebrows, blinking or coughing. Patients with tic disorders will have two parts to the scanning session. First they will relax and allow tics to occur spontaneously, then they will be asked to imitate a specific tic when there is no urge to tic. Patients and healthy subjects will have electromyography (EMG) to record the timing of the voluntary movements and tics. For this procedure, several pairs of small, saucer-like electrodes are attached to the skin with a gel or paste. Electric signals from the electrodes are amplified and recorded on a computer. A microphone may be placed near patients to record any vocal tics. A video camera may also be used to record the tics.
