Filter by:The aim of this study is to evaluate the efficacy and safety of bilateral pallidal stimulation in patients with a severe form of Gilles de la Tourette syndrome.
This study will evaluate the safety and effectiveness of methylphenidate in treating attention deficit hyperactivity disorder in children with both attention deficit hyperactivity disorder and Tourette syndrome.
Tourette's disorder (TD) is a childhood-onset neuropsychiatric disorder, manifesting motor and vocal tics with increased likelihood of comorbid with attention-deficit/hyperactivity disorder (ADHD) and other psychiatric disorders. Literature documents the comorbid condition with ADHD predicts an increased functional deficit among individuals with ADHD. The information about neuropsychological functioning among individuals with TD adn/or ADHD is little in Asian population. This study aims to validate the diagnoses of TD, ADHD, and TD comorbid ADHD by symptomatology, neuropsychological measures, and social adjustment. This is a case-control study with a sample of 30 subjects with TD, 60 with ADHD, 30 with TD+ADHD, and 60 controls aged from 6 to 18. All subjects will receive comprehensive assessment including standard psychiatric diagnostic interviews using (K-SADS-E), behavioral assessments (SNAP-IV, CPRS:R-S, CTRS:R-S, CBCL, YBOCS, YGTSS), social adjustment (SAICA, GCAS), parenting (PBI, APGAR) and neuropsychological assessment (CPT, CANTAB, WISC-III). We anticipate that this study will provide the primitive data to validate the TD and ADHD using neuropsychological and clinical measures.
The goal of this study is to confirm that levetiracetam has a better tic-suppressing profile than that of the widely used tic-suppressing medication, clonidine. More specifically, the investigators hypothesize that in a 15 week placebo run-in, double-blind, medication cross-over trial; levetiracetam will be more effective and have fewer side-effects than clonidine.
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 whether deep brain stimulation is effective at reducing tic frequency and severity in adults with Tourette syndrome.
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).
This study will compare the efficacy of supportive therapy versus habit-reversal therapy for the treatment of Tourette syndrome and chronic tic disorder.
This study will determine the effectiveness of cognitive behavior therapy (CBT) with habit reversal training (HRT) in treating chronic tic disorders (CTDs) in children and adolescents.
Previous studies using topiramate in Tourette subjects have shown that with the use of this medication subjects report that their tics get better. The purpose of this study is to study if topiramate improves the symptoms of Tourette syndrome, such as motor tics, or other associated symptoms such as attention or obsessive-compulsive problems.
