Abstract<\/strong><\/p>\n

Background:<\/strong> Excessive daytime sleepiness (EDS) is different from occasional sleepiness. It is persistent, reduces quality of life and increases risk of accidents. EDS is common in obstructive sleep apnea (OSA) and can be improved by OSA treatment. It has proven difficult to find a comprehensive method for assessing EDS. The most used method is the Epworth Sleepiness Scale (ESS), a short questionnaire that measures risk of dozing. The reliability of the ESS has been questioned, showing weak correlation with other sleepiness measures. This doctoral thesis aimed to explore EDS phenotypes in both the general population and OSA patients.<\/p>\n

Methods:<\/strong> EDS was defined as ESS>10 points (at risk of dozing) and feeling sleepy \u22653 times per week. The doctoral thesis is based on four scientific papers. Paper I assessed EDS in the general population (n=1338). Paper II evaluated EDS in Icelandic OSA patients (n=810) before and after treatment. Paper III validated the findings from paper II in an international group of OSA patients (n=2352) and paper IV examined the polysomnographic characteristics of EDS in the same group of OSA patients (n=2097).<\/p>\n

Results:<\/strong> In the general population, feeling sleepy (17%) was more common than being at risk of dozing (7%) or having both symptoms (6%). Those feeling sleepy had lower quality of life, poorer health and higher prevalence of insomnia symptoms and restless legs syndrome compared to those non-sleepy or only at risk of dozing. Half of the Icelandic OSA patients reported both EDS symptoms. In addition, a quarter reported feeling sleepy without being at risk of dozing. Treatment was less effective for this group. An international study of OSA patients confirmed the Icelandic findings. Sleepiness symptoms showed only a weak correlation with hypoxia, frequency of apneas, sleep depth and arousals measured by polysomnography.<\/p>\n

Conclusions:<\/strong> EDS is a multifactorial symptom associated with health and quality of life. A more comprehensive approach is needed to diagnose EDS.<\/p>\n
