Sleep-talking is very common and is reported in 50% of young children at least once a year. [6] A large percentage of people progressively sleep-talk less often after the age of 25. A sizable proportion of people without any episode during their childhood begin to sleep-talk in adult life. [7] Sleep-talking may be hereditary. [8]
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.

Sleep apnea is the second most frequent cause of secondary hypersomnia, affecting up to 4% of middle-aged adults, mostly men.
