Symptoms are rated on a severity scale as follows:
1-2 Sensation of rocking/bobbing/swaying is almost imperceptible. Most often noticed while walking but may also be recognized while sitting, standing or lying down. Can usually perform routine daily functions without the need for rest periods.
3-4 Rocking/bobbing/swaying sensation is almost constant but can function fairly well with occasional rest periods. The sensation of rocking/bobbing/swaying may include the perception of movement along either a horizontal or vertical axis. The floor seems to move when walking (as if walking on a suspension bridge, water bed, or trampoline). Altered balance. Cannot remain standing in a fixed position with eyes closed.
5-6 Rocking/bobbing/swaying intensity is increased. Accompanied by difficulty in concentration and/or mental confusion (impaired cognitive function). Most routine tasks become difficult to accomplish. Require periods of rest. May stumble when walking.
7-8 Rocking/bobbing/swaying is more severe and noticeable while walking, standing, or sitting. Associated with considerable fatigue. Increased loss of concentration and/or mental confusion. Balance is affected (bump into objects when walking; clumsy in handling objects; may drop things).
9-10 Rocking/bobbing/swaying is extremely severe. Balance is very poor. Require support for walking and standing (have to hold onto walls). Significant mental confusion. Impaired ability to speak. Remain in bed most of the day.
Treatment
While there is no known cure for Mal de Debarquement Syndrome (MdDS), some success in managing symptoms has been realized with medications and vestibular rehabilitation.
Most anticholinergeric medications that work for other forms of dizziness and motion sickness, such as meclizine or scopolamine, are not effective in either treatment or prevention of MdDS.
