Catathrenia or nocturnal groaning is a sleep-related breathing disorder, consisting of end-inspiratory apnea (breath holding) and expiratory groaning during sleep.It describes a rare condition characterized by monotonous, irregular groans while sleeping. [1]
The onset of symptoms is usually within 2 and 3 hours of sleep onset (at the time of transition from slow-wave sleep to a lighter sleep stage) and those events can last from 10 to 30 minutes. Patients generally wake up without any recollection of the event. It is necessary to distinguish confusional arousals in adults from children. [3]
Other sleep related disorders like sleep apnea are ruled out by examining the patients' respiratory effort, air flow, and oxygen saturation. RMD patients often show no abnormal activity that is directly the result of the disorder in an MRI scan. [7] RMD episodes are strongly associated with stage 2 NREM sleep and, specifically, K Complexes [8].

In a study using the Choice Visual Perception Task, subjects were exposed to stimuli appearing in ...
