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.
