4. Discussion
This questionnaire-based study showed poorer sleep quality and a higher frequency of subjective sleep disturbances in a series of 208 epilepsy patients attending our epilepsy outpatient clinic in comparison with 212 age- and sex-matched controls. Our findings confirm the previous reports related to a higher frequency of subjective sleep disturbances in epilepsy patients (de Weerd et al., 2004; Foldvary, 2002; Khatami et al., 2006; Manni et al., 2000). They have higher frequency of sleep onset, maintenance insomnia, probable RBD, and sleep apnea than healthy controls do.
