Clinical Information
- A group of sleep disorders causing disruption of sleep. Representative examples include nightmare disorders, sleep terror disorders, sleepwalking, and restless leg syndrome.
- An abnormal disruption of sleep, such as sleep walking, sleep talking, nightmares, bedwetting, sleep apnea (problems with breathing that cause loud snoring), or nighttime seizures.
- Movements or behaviors associated with sleep, sleep stages, or partial arousals from sleep that may impair sleep maintenance. Parasomnias are generally divided into four groups: arousal disorders, sleep-wake transition disorders, parasomnias of rem sleep, and nonspecific parasomnias.
