Abstract
I investigated the contribution of sleep disorders in unidentified dizziness. In BPPV (Benign Paroxysmal Positional Vertigo) cases where the cause of the dizziness is to a certain degree clear, the average ESS (Epworth Sleepiness Scale) score was 14.9 points. On the other hand, the average score for dizziness in cases of unknown cause was 17.2 points. The ESS score in cases of dizziness of unknown cause was statistically significantly higher. Of the 77 cases with dizziness of unknown cause, Orthostatic dysregulation (OD)-positive accounted for 48 cases (62.3%) with high significance. Twenty-nine cases (37.7%) were negative. It was thought that OD is considered as being present together with sleep disorders in some of the cases that have been diagnosed with dizziness of unknown origin in outpatient care, and this should always be kept in mind.
