Arousal parasomnias (night terrors, sleepwalking, and confusional arousals) have seldom been investigated in the adult general population. Clinical studies of parasomnias, however, show that these disorders may be indicators of underlying mental disorders and may have serious consequences. ⋯ Arousal parasomnias, especially night terrors and confusional arousals, are often the expression of a mental disorder. Other life or medical conditions, such as shift work or excessive need of sleep for confusional arousals and stressful events for sleepwalking, may also trigger parasomnias. Prevalence rates are based on self-reported data and, consequently, are likely underestimated.
