Abstract

Background
There is a clear association between headache and sleep disturbances. However, the mechanism and causes are complex and poorly understood. The aim of this study is to investigate the clinical characteristics of sleep disturbance between migraineurs with insomnia and non-organic insomniacs. Methods: We enrolled 20 migraineurs with insomnia and 22 controls(non-organic insomniacs). Two groups underwent the battery of four sleep tests, such as the Pittsburgh Sleep Quality Index(PSQI), the Stanford Sleepiness Scale(SSS), the Epworth Sleepiness Scale(ESS), and the Insomnia Severity Index(ISI). The Beck Depression Inventory(BDI) and State Trait Anxiety Inventory(STAI) were also performed for evaluating associated comorbid conditions such as depression and anxiety tendency. Results: In the comparison, Migraineurs with insomnia group and control group were statistically differed in the scores of the battery of sleep tests. In the PSQI, the average score of migraineurs with insomnia was 9.95 as compared with 16.55 in control group(p<0.05). Furthermore, the SSS was 2.75 vs. 3.50(p<0.05) and ISI was 12.05 vs. 22.68(p< 0.05). The ESS provided exceptional adverse average scores such as 6.80 vs. 5.41 but the difference was not statistically significant(p>0.05). In the logistic regression, the PSQI was the only significant prospective factor(odds ratio=2.15, p<0.05). The difference of the BDI and STAI was not statistically significant(p>0.05). Conclusions: In this study, migraineurs with insomnia have less sleep complaints than non-organic insomniacs. Depre- ssion and anxiety tendency does not affect on the result.
