Clinical Trial Summary

This study uses a noninvasive technique called transcranial magnetic stimulation (TMS) to study hyperphagia and satiety in Prader-Willi syndrome. TMS is a noninvasive way of stimulating the brain, using a magnetic field to change activity in the brain. The magnetic field is produced by a coil that is held next to the scalp. In this study, the investigators will be stimulating the brain to learn more about how TMS might improve hyperphagia in Prader-Willi syndrome.

Intervention

Device:
• Repetitive Transcranial Magnetic Stimulation (rTMS)
rTMS is a technique of TMS that allows for selective external manipulation of neural activity in a non-invasive manner. During rTMS a rapidly changing current is passed through an insulated coil placed against the scalp. This generates a temporary magnetic field, which in turn induces an electrical current in neurons and allows for modulation of neural circuitry. Other Name: iTBS
