Excessive sleepiness and sleep patterns in patients with epilepsy: A case–control study

Abstract The aim of this study was to assess excessive daytime sleepiness (EDS), sleep quality, and sleep disorders in a cohort of patients with epilepsy in the city of Florianopolis in southern Brazil. One hundred and forty patients diagnosed with epilepsy were assessed by questionnaires that included demographic and clinical variables, the Pittsburgh Sleep Quality Index (PSQI), the Epworth Sleepiness Scale (ESS), the Stanford Sleepiness Scale (SSS), and the Fletcher & Luckett Adapted Questionnaire (FLAQ).
