Brief Summary

Prader-Willi syndrome (PWS) is a genetic disorder usually caused by the deletion of a specific gene. One of the symptoms of PWS is self-injurious behavior (SIB); a common form of SIB in PWS patients is skin picking. The injury may be severe enough to require frequent medical attention. This trial will evaluate SIB in individuals with PWS and will test the effectiveness of the drug topiramate to control SIB.
