Obstructive sleep apnea/hypopnea (OSAH) has been described as a known triggering factor for parasomnias including sexsomnia. Nasal continuous positive airway pressure (nCPAP) has been the standard of treatment for OSAH but mandibular advancement devices (MAD) are becoming an important treatment alternative. We present the case of a patient with mild OSAH and sexsomnia who had resolution of both conditions with a MAD. This patient had the added uniqueness of having REM-predominant OSAH.engParasomniaObstructive sleep apneaDental devicejournal article10.1016/j.slsci.2016.11.002
