Parasomnias are episodes of abnormal or unwanted behavior in sleep. Usually the behaviour is noted by others and not the patient. Parasomnias often include walking, talking, bed wetting or rocking during sleep.
The most common parasomnias are talking while asleep, night terrors, starts or body jerks and REM sleep behavior disorder.
REM sleep behavior disorder is characterized by the patient, usually an older male, acting out his dreams.
In some cases, parasomnia activity is inherited.
Parasomnias do not always need to be treated. When necessary, medications may be used and a consultation with a sleep doctor is warranted.
