Background Rapid eye movement (REM) sleep behavior disorder (RBD) is characterized by recurrent dream enactment behaviors like sleep-related vocalization and/or complex motor behaviors. Objective To investigate the discriminative role of the validated Turkish version of the 9-Item Innsbruck REM Sleep Behavior Disorder Inventory (IRBD-9-Turkish) for idiopathic RBD (iRBD) in patients with obstructive sleep apnea (OSA). Methods The current multicenter study was prospectively conducted in 13 accredited sleep centers in 10 different cities in T & uuml;rkiye. Clinical data was obtained through a preformed questionnaire, and all participants were submitted to a full-night video-polysomnography (video-PSG) session in a sleep laboratory. Results A total of 105 patients (mean age: 58.3 +/- 11.6 years; 68.6% of male subjects) were prospectively and consecutively enrolled in the study; 51 patients (48.6%) presented iRBD, and 54 (51.4%), OSA, 19 (35.2%) of whom presented abnormal nocturnal behaviors (NBs) demonstrated by clinical and video-PSG findings associated with arousal reactions secondary to apneas and hypopneas. The cut-off value of the IRBD-9 was higher in patients with OSA-NBs than in those with OSA without NBs ( p < 0.001), with a sensitivity of 0.765 and a specificity of 0.667, resulting in a correct diagnosis of NBs in 75% of patients with OSA. The receiver operating characteristic (ROC) curves for Factor I (items 1, 2, 3, 6, and 8) and Factor II (items 4, 5, 7, and 9) of the IRBD-9-Turkish showed that both factors were able to distinguish patients with iRBD from those with OSA, but only Factor I distinguishes patients with iRBD from those with OSA-NBs. Conclusion The present study demonstrated a very high sensitivity and specificity of the IRBD-9-Turkish not only in patients with iRBD, but also in patients with OSA.
