Mal de Débarquement syndrome
Mal de Débarquement syndrome is a condition that causes someone to feel like they are still moving after being on a boat, plane, car or train, etc. The feeling usually resolves within 24 hours but is classified as persistent when it lasts greater than one month.
The prevalence of migraine in those with Mal de Débarquement syndrome was 23% in motion triggered individuals and 38% in non-motion triggered subjects (passive motion that occurred less than 2 hours).1
