OBJECTIVES: Catathrenia is an uncommon and poorly understood disorder, characterized by groaning during sleep occurring in tandem with prolonged expiration. Its classification, pathogenesis, and clinical relevance remain debated, substantially due to the limited number of cases reported to date. We report a series of consecutive cases of catathrenia, their clinical and polysomnographic characteristics, and their subsequent management. METHODS: Consecutive patients with catathrenia who had undergone full polysomnography in our institution over a 5...

BACKGROUND: Catathrenia is a rare sleep disorder characterized by repeated groaning in a protracted expiration preceded by a deep inspiration. This study aimed to explore whether anatomy is one of pathophysiology of catathrenia by investigating the anatomical features associated with catathrenia in the upper airway, craniofacial structures, and dental patterns. MATERIAL AND METHODS: Twenty-two patients with catathrenia (7 males, 15 females; age 22 to 69 years) were recruited as well as 66 patients matched by age and gender (matching proportion 1:3) with obstructive sleep apnea syndrome (OSAS)...

BACKGROUND: The International Classification of Sleep Disorders-Third Edition (ICSD-3) classifies catathrenia among the respiratory disorders and not as a parasomnia as in ICSD-2. Few patients have been reported during these years, and the clinical description of the sound is different from group to group. In fact, there is no full agreement about its nature, origin, meaning, and treatment. METHODS AND RESULTS: In this paper we review the literature on catathrenia focusing on the characteristics of the sound, demographics of the patients, aetiology, response to treatment, etc...

SESSION TYPE: Miscellaneous Cases IIPRESENTED ON: Tuesday, October 23, 2012 at 11:15 AM - 12:30 PMINTRODUCTION: Catathrenia, derived from the Greek word (kata-like, threnia-to lament), is a sleep-related respiratory condition described as high pitched, monotonous groaning, moaning, respiratory dysrhythmia with bradypnea and vocalisation or inarticulate expiratory phonation. Clearly a rare disorder, its actual incidence and prevalence are unknown with a limited number of cases presented in the literature.CASE PRESENTATION: A fourteen year old boy with a history of bronchial asthma presented for evaluation of snoring and witnessed apneic episodes...

OBJECTIVE: Catathrenia (nocturnal groaning) is a rare condition characterized by monotonous irregular sounds that occur during sleep. Not infrequently, catathrenia has been confused with expiratory snoring. We aimed to clarify the subtypes of catathrenia and differentiate them from snoring using sound analyses. METHODS: We enrolled five patients with catathrenia who were confirmed by overnight polysomnography (PSG). They underwent clinical and physical evaluation, including craniofacial and oromandibular examination, and fulfilled sleep-related questionnaires...

PURPOSE: This study aims to report on catathrenia occurring in narcolepsy with cataplexy (NC) patients under sodium oxybate (SO) treatment. Catathrenia is a parasomnia characterized by groaning and an abnormal respiratory pattern during sleep. METHODS: Fifty-one patients with NC and starting SO therapy underwent a baseline overnight polysomnography (PSG) to detect any sleep-related breathing disorders (SRBD). To avoid risks due to a possible central respiratory control depression by SO, all patients with concomitant obstructive sleep apnea (OSA) were treated with a nasal continuous positive airway pressure (nCPAP) device...

BACKGROUND: It is estimated that about 25% of children have sleep disorders, from short problems with falling asleep to severe including primary sleep disorders. Majority of these problems are transitory and self-limiting and usually are not recognized by first care physicians and need education. AIM OF THE STUDY: Analysis of sleep structure at the developmental age and of sleep disorders associated with different sleep phases on the basis of video/polysomnography results...

PURPOSE: Descriptions of nocturnal vocalizations, including catathrenia, are few. We undertook a study at our center on patients diagnosed with catathrenia, to evaluate the characteristic features of these events and their response to continuous positive airway pressure (CPAP) treatment. METHODS: Retrospective study of patients with a diagnosis of catathrenia who had an overnight polysomnogram (PSG) and available synchronized audio video recordings (to confirm the presence of moaning and groaning), at our center between January 2007 and May 2010...

PURPOSE: Catathrenia (nocturnal groaning) is a rare and relatively little-understood parasomnia. The characteristics of the sound and the recordings are not similar in all the relevant research papers. Indeed, there is currently some discussion regarding whether or not this is a single entity. For some authors, catathrenia is a particular form of parasomnia; for others, it may be a variant of snoring or a respiratory problem. The goal is to establish whether or not catathrenia may be regarded as an expiratory vocal sound...

We report the case of a patient with idiopathic generalized epilepsy who ten years after the onset of his epilepsy also developed recurring nocturnal paroxysmal episodes reminiscent of his seizure semiology. Video monitoring and polysomnography revealed episodes of nocturnal groaning. Escalation of antiepileptic treatment was avoided.

BACKGROUND AND OBJECTIVE: Nocturnal groaning (catathrenia) is a chronic sleep disorder classified as parasomnia with unclear effects on sleep and life quality. It is characterized by repeated episodes of monotonous vocalization in prolonged expiration (episodes of bradypnea) occurring mostly in REM sleep. We sought to assess its impact on sleep microstructure, i.e., the frequency of arousals relative to the groaning episodes. The frequency, duration and sleep-stage distribution of the groaning episodes were also studied...

INTRODUCTION: Catathrenia is a rare, idiopathic, sleep-related respiratory condition characterized by irregular groans, which occur during prolonged expiration in sleep. The origins of catathrenia remain inexplicable, the long-term prognosis unexplained. Moreover, empirical treatment with neither pharmacological nor non-pharmacological approaches was satisfactory. CASE REPORT: We report a case of catathrenia with concurrent obstructive sleep apnea complicated with pulmonary hypertension and reviewed the literature...

OBJECTIVE: We report a series of seven consecutive cases of catathrenia (sleep related groaning) that differ from limited previous reports in the literature with regard to sleep stage and response to treatment. BACKGROUND: Catathrenia was recently defined as a parasomnia in the International Classification of Sleep Disorders Diagnostic and Coding Manual (ICSD-2), but there is debate about its classification, and its response to CPAP is unknown. METHODS: We present 7 consecutive patients presenting with catathrenia over a 5-year period...
