Will another cruise or travel cause MdDS to return? Or worsen?

Not necessarily. Some individuals whose MdDS had resolved redeveloped symptoms after a subsequent cruise or motion experience, while others did not.

Some individuals report a temporary increase in symptoms after subsequent travel, and many describe a more prolonged period of symptoms with each consecutive episode. Therefore, the recommendation is to avoid further cruises to minimize the likelihood of recurrence.

Your physician may suggest using benzodiazepines to suppress the vestibular system during travel. While many patients claim this helps, clinical studies are required to prove effectiveness across the broader MdDS population.

Whether the duration or intensity of initial symptoms influences the likelihood of recurrence remains unknown. The MdDS Patient Registry launching in 2026 aims to collect data to better answer questions like this one. Learn more about the Registry on this page.
