The aim of this study was to support the growing evidence suggesting that Prader-Willi Syndrome (PWS) might present with an impairment of executive functions (EFs) and to investigate whether this impairment is specific to patients with PWS or due to their intellectual disability (ID). Six tasks were administered to assess EFs (inhibition, switching, updating, cognitive estimation, and planning) to 17 patients with PWS and 17 age-matched healthy individuals. Performance was significantly impaired in the PWS group on all EFs and after controlling for IQ level, intergroup differences remained only for switching and cognitive estimation. In conclusion, PWS seems to be associated with a global impairment of EFs that appears to be closely linked with intellectual impairment but also with the PWS itself.
