Mal de Debarquement Syndrome with Apogeotropic Positional Nystagmus

ABSTRACT

Mal de debarquement syndrome refers to the prolonged sensation of rocking and swaying that is experienced on the return to land following a sea voyage or an air travel. We report a man who developed mal de debarquement syndrome after a 4-day-boat-trip. Apogeotropic nystagmus during head turning in supine position was the only finding. Mal de debarquement syndrome should be considered in the differential diagnosis of direction-changing positional nystagmus, especially when patients do not complain of vertigo with nystagmus.
