다국어 초록 (Multilingual Abstract)

Objects : The authors studied polysomnographic findings of patients with sleep apnea DIMS (disorders of initiating and maintainig sleep) syndrome and anxiety disorders with insomnia related to another mental disorders.
Methods : Eight patients with sleep apnea DIMS syndrome and fourteen patients with anxiety disorder with insomnia related to another mental disorder(nonorganic) were studied using computerized polysomnography.
Results :
1) The sleep period time were significantly decreased in anxiety disorder group and the sleep latency was prolonged in these patients.
2) The changes in sleep stage and the number of arousals during sleep period time were more frequent in sleep apneic patients group. And using these variables we could discriminate sleep apneic patients group from subjects with anxiety disorder.
3) The stage 1 sleep was significantly increased in sleep apneic patients.
4) The apnea index in sleep apnea patients was 28.1±25.7.
Conclusion : These results suggested that even though there were similiar clinical presentaion such as insomnia, the sleep features of sleep apnea DIMS syndrome and anxiety disorder with insomnia were different. And though there were no instruments to check respiratory flow or movement, it would be possible to discriminate the sleep apnea DIMS syndrome from the anxiety disorder with insomnia by recording the changes in sleep stage and the number of arousals in overnight electroencephalographic procedure.
