Mal de debarquement syndrome is defined by a persistent sensation of rocking and 
swaying commonly felt with sea travel that is first noted on return to land. Mal 
de debarquement syndrome is not to be confused with seasickness, which causes 
nausea, vomiting, diaphoresis, and headache. Four female patients with mal de 
debarquement syndrome are reviewed. Mal de debarquement is normally a 
short-lived phenomenon. The need for extensive evaluations may be avoided by an 
awareness of this entity.
