title: Clinical study of insomnia, a common disorder in primary care: from a viewpoint of consultation-liaison psychiatry.
abstract: A total of 100 new patients was investigated who consulted the Department of Psychiatry of Tosei General Hospital concerning insomnia as a chief complaint. The average age of the subjects was 52, with an age range of 13-88, and a male female ratio of 1:22. According to the DSM-III-R classification, primary sleep disorder was most frequent (39%), followed by affective disorders (34%), organic mental disorders (9%), anxiety disorders (6%), psychoactive substance use disorders (4%), psychotic disorders not elsewhere classified (4%), and others. Various psychosocial stressors were observed in 40% of the subjects, and concurrent major physical disorders in 44% of the subjects. Based on the results, the role of consultation-liaison psychiatry in treatment of sleep disorders and primary care was discussed.
