This study will look at the effects of treatment combining Comprehensive Behavioral Intervention for Tics (CBIT) and Transcranial Magnetic Stimulation (TMS) for young people who have tic disorder. Participants must be 12- 21 years old and able to have an MRI. All participants will receive 10 daily sessions of CBIT, a well-established behavioral treatment that is considered to be the first treatment for tics. Participants will also be assigned randomly (by chance) to receive TMS or a sham (treatment not delivered) just before each CBIT session. The device for TMS delivers electromagnetic stimulation to a specific area of the brain with a small coil on the scalp. The effectiveness of the CBIT for the two groups, with and without the TMS, will be compared.

This study is about understanding how TMS affects the balance between inhibitory and facilitatory processes in the motor cortex. The study includes an experimental device, specifically transcranial magnetic stimulation (TMS), electroencephalography (EEG), and electromyography (EMG). TMS is a non-invasive brain stimulation method to probe brain activity. EEG is used to record brain activity through electrodes placed on the head, while EMG measures muscle activity through sensors attached to the skin.

This study is about how pain affects drinking behaviors in people with chronic temporomandibular disorder (TMD).

The purpose of this study is to test the effects of an in person or home-based exergame intervention on improving cognition and fitness in community-dwelling older adults with memory complaints. The exergame refers to a new low-cost virtual reality cognitive game with cycling. We expect that participants will be in this research study for 4 months. Intervention sessions will require approximately 1 hour, 3 days per week for 3 months.

The purpose of this study is to determine how different bladder management methods affect the quality of life for young people with spina bifida. We hope to find out if certain bladder management methods are associated with a better quality of life. This information could help doctors make better treatment decisions and counsel young people living with spina bifida.

This research will use neuroimaging to study the brain systems involved in prioritizing goals effectively, as well as testing whether variation in those systems is associated with the personality trait conscientiousness, which reflects organization, self-discipline, and industriousness and predicts important health and other life outcomes.

Humanitarian use devices are medical devices approved by the FDA for the treatment of medical conditions affecting fewer than 4,000 patients per year. The FDA reviewed the safety of the device and determined that the probable health benefits outweigh the risks of injury or illness from its use. Effective treatment of symptoms, however, has not been studied in formal clinical trials. Medtronic DBS Therapy delivers electrical stimulation to areas in the brain to help control symptoms of various movement disorders. You may be a candidate for Medtronic DBS Therapy for Dystonia if you have been diagnosed with chronic, intractable (drug refractory) primary dystonia. You or your third party payer (health insurance, Medicare, Medicaid or other) must provide payment for hospital, office and other medical costs related to this therapy.
