Received December 7, 2014 Revised December 15, 2014 Accepted December 23, 2014 Address for correspondence Jae-Wook Cho, MD Department of Neurology, Pusan National University Yangsan Hospital, Pusan National University School of Medicine, 20 Geumo-ro, Mulgeum-eup, Yangsan 626-770, Korea Tel: +82-55-360-3014 Fax: +82-55-360-2152 E-mail: sleep.cho@gmail.com Rapid eye movement (REM) sleep behavior disorder (RBD) is characterized by dream-enacting behaviors during REM sleep. However, many sleep disorders can produce RBD mimicking symptoms, also known as ‘pseudo-RBD’. We report a patient with severe obstructive sleep apnea with ‘pseudo-RBD’ symptoms that were eliminated by continuous positive airway pressure treatment. Polysomnography is mandatory to establish the proper diagnosis of RBD. J Korean Sleep Res Soc 2014;11(2):72-75
