PWS Activity, Sleep and Eating Pattern Pilot Study

Dr. Panda at the Salk Institute for Biological Studies, is conducting a pilot study to examine the daily patterns in activity, sleep, and food/beverage intake in individuals diagnosed with Prader-Willi Syndrome.

Participants will wear an actiwatch to passively track activity and sleep for 2 weeks. Adult participants (ages 18-65 years) will also use a smartphone app to track eating and drinking patterns, sleep, and activity.


Individuals 13-65 years old diagnosed with Prader-Willi Syndrome, and live in the United States, are eligible to participate. Adolescents 13-17 will also need parental consent.
