초록
Catathrenia(nocturnal groaning) is a rare disorder recently classified as a parasomnia. We presented three cases of catathrenia which of them performed continuous positive airway pressure (CPAP) titration. All patients had same patterns of breathing during catathrenia sound which recorded in polysomnography as central sleep apnea starting with deep inspiration. Catathrenia predominantly occurred in the last REM sleep period in case 1 but in all stages in case 2. Case 3 had all catathrenia in NREM sleep. Case 2 and 3 had combined obstructive sleep apnea (Apnea-hypopnea Index=21.7/hr and 20.5/hr). Case 1 and 2 performed CPAP titration. With or without combined obstructive sleep apnea, catathrenia events were remarkably decreased.
