Mal de Debarquement Syndrome (MdDS) or disembarkment syndrome is a rare disorder of perceived movement that most often develops following an ocean cruise, other type of water travel, or motion experience including plane flights and train travel. For a few, there is no known motion event; the onset appears to be spontaneous. MdDS persists for months to years. common symptoms include a persistent sensation of motion such as rocking, swaying, tumbling, and/or bobbing. This sensation of motion is often associated with anxiety, fatigue, difficulty maintaining balance, unsteadiness, and difficulty concentrating (impaired cognitive function). Often, the motion sensation seems to disappear when riding in the car or participating in other motion experience.
