Cerebellar TMS and Satiety in Prader-Willi Syndrome
Noninvasive Neuromodulation of a Novel Cerebellar Satiety Circuit in Prader-Willi Syndrome

INTERVENTIONAL
Conditions
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.
Eligibility
Inclusion Criteria1
- Diagnosis of Prader-Willi syndrome
Exclusion Criteria6
- contraindications for TMS or MRI including :
- history of neurological disorder
- history of head trauma resulting in loss of consciousness
- history of seizures or diagnosis of epilepsy or first degree relative family history of epilepsy
- metal in brain or skull
- implanted devices such as a pacemaker, medication pump, nerve stimulator or ventriculoperitoneal shunt claustrophobic in MRI

Interventions
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
