Objective: To determine the causative factors and epidemiology of bilateral vestibulopathy (BV).
Methods: This is a retrospective review of 255 patients (mean age, 62 +/- 16 years) with BV diagnosed in our dizziness unit between 1988 and 2005. All patients had undergone a standardized neurophthalmological and neurootological examination, electronystagmography with caloric irrigation, cranial magnetic resonance imaging or computed tomography (n = 214), and laboratory tests.
