Catathrenia
Catathrenia
Catathrenia (pronounced: kəˌθrēnēə) is a rare sleep disorder characterized by abnormal vocalizations during sleep, specifically groaning sounds.
Etymology
The term "Catathrenia" is derived from the Greek words "kata", meaning "down" and "threnia", meaning "to lament". It was first used in medical literature in 1983.
Symptoms
The primary symptom of Catathrenia is the production of high-pitched groaning sounds during sleep. These sounds are often mistaken for snoring, but are distinct in their tonal quality and duration. Other symptoms may include sleep disruption for the individual or their bed partner, and potential daytime sleepiness due to disturbed sleep.
Causes
The exact cause of Catathrenia is unknown. However, it is believed to be related to abnormalities in the nervous system's control of muscles involved in respiration during sleep. Some studies suggest a link between Catathrenia and sleep apnea, a condition characterized by pauses in breathing during sleep.
Diagnosis
Diagnosis of Catathrenia is typically made through a sleep study, also known as polysomnography. This involves monitoring the individual's sleep patterns, brain waves, heart rate, and breathing patterns during sleep. The characteristic groaning sounds of Catathrenia can be identified during this study.
Treatment
Treatment for Catathrenia is typically focused on managing the symptoms and improving sleep quality. This may involve the use of Continuous Positive Airway Pressure (CPAP) therapy, a common treatment for sleep apnea that can also be effective in managing Catathrenia.
