    General Discussion
    Mal de debarquement syndrome (MdDS) is a rare and little understood disorder of the body?s balance system (vestibular system) and refers to the rocking sensation and/or sense of imbalance that persists for an excessive length of time after an ocean cruise, plane flight or other motion experience. Most people after exposure to an ocean trip or long airplane ride will experience motion after the event is over and for a short period of time. But for persons with MdDS, these sensations may last for six months or a year or even many years. Symptoms may diminish in time or periodically disappear and reappear after days, months, or years, sometimes after another motion experience or sometimes spontaneously. This syndrome is probably more common than the literature might lead us to believe, as the level of awareness in the general population as well as among health personnel is very low.

    The disproportionate length of time over which the discomfort persists is normally unaccompanied by nausea, nor is it responsive to motion-sickness drugs.

    For reasons that are not understood, women are overwhelmingly more likely to come down with MdDS than are men. However, most studies so far have disavowed hormones as a cause.
