The NSDA is comprised of people with SD, healthcare professionals, volunteers, friends, and families. It is the only organization dedicated solely to the SD community. Together, we continue to grow through awareness, advocacy, and outreach; help to improve the lives of people dealing with SD; and work to support research in order to bring understanding to this disorder.
