Tic disorder

This study is testing a computer program called DystoniaNet that uses artificial intelligence to help doctors diagnose isolated dystonia, a movement disorder. The trial will enroll 1000 people with dystonia or other conditions that look like it, such as Parkinson's disease or ess…

This trial tests whether a therapy that blends Exposure and Response Prevention (ERP) with Habit Reversal Training (HbRT) can reduce both obsessive-compulsive and tic symptoms in adults with Tourettic OCD — a subtype where OCD and tic disorders overlap. Standard treatments usuall…

This trial tests whether sertraline, a widely used antidepressant, can reduce anxiety in children and teens aged 8 to 17 with neurodevelopmental disorders such as autism, ADHD, Fragile X syndrome, and Tourette syndrome. Participants receive either sertraline or a placebo for seve…

This study tests whether a mindfulness-based program can help adults with Tourette syndrome or persistent tic disorders reduce their tics. Participants will either learn mindfulness techniques to manage urges or receive standard relaxation and coping support. The goal is to see w…

This study is testing a behavioral treatment called CBIT (Comprehensive Behavioral Intervention for Tics) in 200 youth who have tic disorders, such as Tourette's, along with related emotional problems like anxiety or depression. The goal is to see if CBIT can reduce tic severity …

This study tests a personalized, non-invasive brain stimulation technique (TMS) in 60 children aged 5-18 with tic disorders. The goal is to reduce tic severity and understand how the brain changes with treatment. Children also receive behavioral guidance, such as avoiding trigger…

This study aims to find differences between organic tics (related to diagnosed disorders) and functional tics (caused by problems in brain-body communication). Researchers will use sensors to measure muscle activity and brain waves in 75 adults with tics and healthy volunteers. P…

This study investigates how the gut-brain axis—the communication network between gut bacteria and the brain—might be involved in pediatric obsessive-compulsive disorder (OCD). Researchers will compare gut microbiome, blood metabolites, brain imaging, and EEG data from children wi…

This study tracks how tic symptoms change in 30 youth aged 12-17 with Tourette syndrome or chronic tic disorders. Participants receive 8 sessions of behavioral therapy (CBIT) and complete daily surveys, wear a device to track physiology, and perform weekly tasks. The goal is to i…

This study records brain activity from people with movement disorders like Parkinson's disease, essential tremor, and dystonia. Researchers use scalp electrodes or existing deep brain stimulators to measure electrical signals. The goal is to find patterns linked to symptoms, whic…

This study uses magnetoencephalography (MEG), a non-invasive brain scan, to compare brain signals in 1,500 children with neurodevelopmental disorders (like epilepsy, autism, ADHD) and healthy children. The goal is to improve diagnosis and understanding of these conditions. No tre…

This study follows 30 people aged 12 to 21 with chronic tic disorders as they go through 8 sessions of CBIT, a well-established behavioral therapy. Researchers will track tic severity, controllability, and other factors to see what predicts a good response. The goal is to underst…

This study looks at 50 people with OCD or Tourette syndrome to find clear differences between compulsions and tics. Participants wear a smartwatch and a portable brain-wave recorder at home and in the lab. The goal is to help doctors choose the right treatment by using objective …

This study aims to learn more about sensory and movement difficulties in adolescents with tic disorders, like Tourette syndrome. Researchers will compare teens with and without tics using questionnaires, brain wave tests, and motor tasks. The goal is to identify factors that affe…

This registry will enroll 450 adults with tic disorders to study how tic severity relates to quality of life, and whether this relationship differs between men and women. Participants will complete questionnaires about tics, mood, and daily functioning. The goal is to better unde…
