Data Collections – Help us help you!

PWSA (USA) currently has the largest collection of information on children with Prader-Willi Syndrome, but some of it is out of date and all data on families lacks essential information that could be crucial information to improve the medical care of our children. Therefore, we are going to improve our database by increasing the size and accuracy of the information.

The graph on theright is derived from our survey as of December 2010.  As of June 2014 there were 1,964 people with PWS in the database and it is still growing! Once your first survey is submitted and processed, you can edit your entry with the second option below. For those wishing to submit an hard copy, the form is available for download too.

In a perfect world, PWSA (USA) would have the names and pertinent information needed on all persons with the syndrome. There is power in numbers! If we can acquire a more comprehensive database, National Institutes of Health (NIH) and other funding sources will be more willing to help our children through funding continued research in PWS and obesity! You do not need to be a member of PWSA (USA) to be included in this collection.
