ABSTRACT

Catathrenia is a sleep-related respiratory disorder characterized by groaning during sleep. This situation is usually not noticed by the affected individuals themselves but is often indicated by family members or bed partners. This disorder, the cause of which is not completely known, is extremely rare. In this case report, a patient who admitted with a complaint of groaning and diagnosed with catahtrenia by polysomnography was presented with its clinical and electrophysiological features. In addition to drawing attention to the fact that catathrenia may be confused with the central sleep apnea pattern in polysomnography, it was emphasized that it should be considered in the differential diagnosis because of a limited number of cases reported in the literature.
