Abstract
Excessive daytime sleepiness (EDS) is the major symptom of patients with obstructive sleep apnea syndrome (OSAS). In this study, we examined the relationship between subjective EDS scored with the Epworth Sleepiness Scale (ESS), objective EDS measured with the multiple sleep latency test (MSLT) and sleep variables evaluated with polysomnography for patients with OSAS. Subjects were 10 patients (51.7 ± 19.0 years old). The average ESS and MSLT scores were 10.6 ± 5.6 and 7.7 ± 5.6, respectively. There was no significant relationship between ESS and MSLT. The Multiple Sleep Latency Test had a significant negative relationship with the number of awakenings and the apnea/hypopnea index. No relationship was found between nocturnal hypoxia and either ESS or MSLT. Our findings suggest that objective EDS in OSAS is related with fragmentation of sleep, and that several patients are not aware of their EDS.Keywords
