Sleep talking can occur during any stage of sleep. The lighter the sleep, the more intelligible the speech: in stages 1 and 2, people may have entire conversations while in stages 3 and 4, speech may be restricted to moans and gibberish. Symptoms can vary in severity and duration.
- Mild: episodes occur less than weekly,
- Moderate: episodes occur more than once per week but less than nightly and cause mild disturbance to a bed partner
- Severe: episodes occur nightly and may cause pronounced interruption of a bed partner’s sleep.
Duration Criteria :
- Acute: 1 month or less.
- Subacute: More than 1 month but less than 1 year.
- Chronic: 1 year or longer.
In addition to speech or utterances during sleep, other symptoms of sleep talking may include:
- Sleep Terrors
- Confusional Arousal s
- Obstructive Sleep Apnea Syndrome
- REM Sleep Behavior Disorder
- Psychiatric Disorders
