Mal De Debarquement Syndrome (MDDS) involves a persistent sense of motion, which is usually described as rocking or swaying that occurs after an inciting event (typically a boat trip such as a cruise). Its name is French for “the sickness of disembarking”. While most people will take a few days to feel completely back to normal after a long voyage, MDDS sufferers can have persistent symptoms for months or even years. Paradoxically, symptoms can improve during passive motion, such as being in the back of a car. Vestibular and audiometric testing is usually normal with MDDS. Treatment consists of medications (like SSRIs), stress reduction, vestibular physical therapy, and treatment of co-existing disorders that can contribute to symptoms (e.g. migraine or anxiety). Promising new 
treatments for patients who don’t respond to the usual treatments involve transcranial magnetic stimulation, and modulation of the VOR (vestibulo-ocular reflex).
