About this trial

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.

Design model

Single group

Treatments tested in this trial

  • Repetitive Transcranial Magnetic Stimulation (rTMS)

    Device

    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

Trial outcomes

Primary outcomes

1

Retention of subjects in study assessments

Retention of subjects for assessments at baseline and 1-week post-TMS follow-up visit, as measured by the percentage (%) of enrolled subjects who complete baseline assessments and then go on to complete the 1-week post-TMS follow-up visit.

Time frame
1-week post-TMS follow-up visit
2

Time required to enroll subjects into study

Time required to enroll the target sample size (n=12) into the study

Time frame
At study completion, up to 18 months
3

Change in BOLD response

Change in functional activation of the cerebellum and ventral striatum will be assessed before (baseline) and after TMS stimulation (1-week post-TMS follow-up visit)

Time frame
baseline, 1-week post-TMS follow-up visit
