In this article, the author describes the common manifestation of sleeptalking, an isolated symptom and a normal variant of sleep behavior of a benign nature. Sleeptalking may have a genetic background. The content may be meaningless or have emotional valence and also may be extensive or reduced to simple moaning or vocalization. No specific treatment for sleeptalking exists, although attention to sleep hygiene and treatment of an underlying disorder that precipitates the sleeptalking is usually helpful. The author reports that, especially in children, sleeptalking is often part of the disorders of arousal typical of that age group. Moaning, screaming, or nonsensical words are often heard by parents, heralding sleepwalking or sleep terror episodes. Also, sleep disordered breathing (SDB) or any kind of sleep deprivation may associate or precipitate sleeptalking. Other factors unrelated to sleep include febrile illness, stress/anxiety, and other mental health conditions (05).
