초록
목적：만성불면증은 흔하고 가장 환자들을 괴롭히는수면장애들 중 하나이다. 본 예비연구는 불면장애 환자들과수면을 잘 취하는 건강인 간에 공간인지기능을 비교하기 위해 수행되었다. 연구대상 및 방법：DSM-5상 불면장애의 진단기준을 만족하는 22명의 만성 불면장애 환자와 27명의 수면을 잘 취하는 정상대조군이 연구에 참여하였다. 전산화신경인지기능검사인 Cambridge Neuropsychological Test Automated Battery (CANTAB)를 시행하여 불면장애 환자와 정상대조군 간에 공간인지기능(spatial planning function)을 비교하였다. 결 과：CANTAB 결과 상 Stockings of Cambridge test 에서 더 저조한 problems solved in minimum moves 결과를 보였다(t = -2.499, p = 0.017) 이 항목은 나이, 성별, beck depression index 비수면점수를 통제한 ANCOVA 분석에서도 유의한 결과를 보였다(F = 5.631, p = 0.017)의 유의한차이가 관찰되었다. 결 론：본 연구의 결과는 불면장애 환자들의 저조한 공간계획기능을 시사한다.
Abstract
Objectives: Chronic insomnia disorder is a common and one of the most distressing sleep disorders. This pilot study was conducted to compare the spatial function between insomnia disorder patients and good sleeping control. Methods: We enrolled the 22 patients with chronic insomnia during over one year who met the DSM-5 diagnostic criteria of insomnia disorder and 27 normal sleeping controls. The Cambridge Neuropsychological Test Automated Battery (CANTAB) has been performed to compare the spatial cognitive function between insomnia disorder patients and good sleeping controls. Results: The CANTAB results showed significant differences in the problems solved in minimum moves of Stockings of Cambridge test (t = -2.499, p = 0.017). The significant difference between two groups remained after controlling age, sex, and Beck Depression Index non-sleep scores (F = 5.631, p = 0.022). Conclusion: This study suggests that the patients with insomnia disorder have poor spatial planning function.
