“…6 The classic PSG description of catathrenia is a deep inhalation followed by protracted exhalation during which moaning or groaning sounds are produced, usually lasting between 2 and 49 seconds. 5,7 Our patient demonstrated these features in the PSG and this is shown in Figure 1 and Figure 2 (marked by A). The response of catathrenia to treatment with either medications or continuous positive airway pressure (CPAP) is variable, with some studies showing improvement or even elimination, while others show no improvement.…”

A 37-year-old non-sleepy (Epworth Sleepiness Scale score of 8) female with a history of depression, obesity, and restless leg syndrome underwent a polysomnography (PSG) for evaluation of daytime fatigue and sleepiness. The split-night PSG revealed an apnea-hypopnea index (AHI) of 15/hour. However, vocalizations were noted during the diagnostic portion of the night that disappeared during the later portion of the study. A sample video PSG fragment with the nocturnal vocalizations is presented in Video 1.

“…17 Recent studies have demonstrated that catathrenia, or catathrenia-like symptoms, can be successfully treated with continuous positive airway pressure (CPAP) in adult patients. 18 This suggests that catathrenia results from upper airway resistance and occlusion during exhalation. The origin of the sounds during catathrenia is different from inspiratory snoring, again suggesting a different mechanism, namely upper airway resistance.…”

“…Once aware of it, people with catathrenia tend to be awakened by their own groaning as well. [2][3][4][5] Due to limited familiarity with the condition, catathrenia is often confused with sleep talking or snoring. 6 Although catathrenia was originally described as a single case report by De Roeck et al in 1983, 7 there have since been several reports from various institutions around the world.…”

Study Objectives: Catathrenia is an underrecognized nocturnal vocalization phenomenon that can be a source of perplexity to patients, bed partners, and medical providers. Catathrenia is distinct from both sleep talking (a parasomnia with loud talking during sleep) and snoring (noise due to vibration of upper airway soft tissues related to variations in airway resistance). The objective of this review is to provide an evidence-based resource to help the practitioner reliably evaluate and manage patients with this condition. Methods: Data were gathered from: (1) PubMed, Scopus, Web of Science, and Google Scholar; and (2) catathrenia social media groups (Yahoo and Facebook). Results: Data collected were (1) 15 case reports and 17 case series describing 191 patients with catathrenia; (2) questionnaires from 47 catathrenia subjects; (3) 5 audio files. Conclusions: Catathrenia is a noise produced during sleep (distinct from snoring) with identifiable harmonics, a computable main frequency, and highdecibel intensity that involves active adduction and vibration of the vocal cords during expiration. The quality of groaning in catathrenia is monotone, and often presents with a morose or sexual connotation, causing a significant social problem for patients. Although there is no association with risk of physical harm, catathrenia does present a significant disturbance to the bed partner and has been associated with subjective impairments to sleep quality, including unrefreshing sleep and fatigue. Polysomnography can be useful if performed properly to confirm the diagnosis and to evaluate for comorbid sleep disturbances, such as obstructive sleep apnea or parasomnia. Directions for further research could involve consideration of deep breathing exercises, yoga, meditation, or myofunctional therapy to help abate symptoms.
