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.
