Usefulness of an original questionnaire for the sleep pattern analysis in distinguishing between some psychopathological syndromes

: By the use of an original questionnaire constructed by the authors, sleep patterns in 194 patients with mental disorders admitted to the hospital were investigated. Six main psychopathological syndromes were diagnosed in this group. The results suggest that most of these syndromes exhibit their characteristic sleep patterns. Our questionnaire seems to be a simple and reliable tool helpful in comparing psychopathological syndromes between them.
