The MdDS Foundation is a registered 501(c)(3) nonprofit organization dedicated to raising awareness and supporting research into Mal de Débarquement Syndrome (MdDS), a neurological disorder that causes persistent sensations of rocking and swaying, often after exposure to motion such as travel by boat, plane, train, or car. The Foundation helps patients, families, and health professionals better understand the condition and navigate the challenges of diagnosis and daily life.

Its website provides information about MdDS symptoms, frequently asked questions, diagnosis, coping strategies, disability coverage, and ways to find support. Patients can learn about and join the global MdDS patient registry, which aims to help researchers understand the disorder’s natural history. The Foundation also shares patient stories, news, educational materials, and professional resources, including guidance for clinicians diagnosing MdDS.

To advance research, the organization publishes biomedical literature and offers grant opportunities. In partnership with the American Brain Foundation, it supports a Next Generation Research Grant for early-career researchers studying MdDS mechanisms and potential treatments.
