Abstract

Catathrenia is a rare sleep disease characterized by monotonous groaning sounds that appear to be related with prolonged expiration, commonly experienced during rapid eye movement (REM) sleep. Catathrenia is also known as nocturnal groaning or sleep-related groaning and is currently categorized as a sleep-related breathing disorder. We present a rare case of a 19-year-old male with nocturnal groaning during non-REM sleep. We suggest that if catathrenia is suspected, polysomnography should be utilized to differentiate it from various sleep disorders such as snoring, central sleep apnea, sleep talking, parasomnia, and sleep-related movement disorders.
