The main objective of the study was to evaluate excessive daytime sleepiness (EDS) in patients with epilepsy from a tertiary outpatient clinic in Rio de Janeiro, Brazil.
Ninety-nine unselected patients from the epilepsy outpatient clinic were invited and their sleep-wake habits were assessed by means of a clinical interview and four validated instruments: Epworth Sleepiness Scale, Beck Depression Inventory, Beck Anxiety Inventory, and the Basic Nordic Sleep Questionnaire. Sociodemographic information and characteristics of the epilepsy syndrome were collected.
Complaints about EDS (Epworth Sleepiness Scale score >10) were reported by 47.5% (95% CI: 37.3-57.7) of the patients. In the sample, 52.6% (95% CI: 0.41-0.60) were overweight or obese, and 53.1% (95% CI: 0.43-0.62) had less than 8 years of formal education. Mainly anxiety, but also neck circumference, was correlated with EDS. Our patients did not exhibit quantitative sleep deprivation. No other epilepsy-related variable showed relationship with EDS. The prevalence of EDS in our population was higher than in similar studies performed in other countries. This finding does not seem to be related to epilepsy itself, but rather to other clinical factors, such as neck circumference, and mainly psychiatric factors, such as anxiety.
Psychiatric comorbidities such as anxiety are linked to EDS and should be recognized and treated. More studies based on objective sleep quality analysis are needed to help elucidate these relationships in the Brazilian population.
本研究的主要目的是评估来自巴西里约热内卢一家三级门诊的癫痫患者的日间嗜睡（EDS）。
邀请了 99 名来自癫痫门诊的未选择患者，并通过临床访谈和四项经过验证的工具评估他们的睡眠-觉醒习惯：Epworth 嗜睡量表、贝克抑郁量表、贝克焦虑量表和基本北欧睡眠问卷。收集了社会人口统计学信息和癫痫综合征特征。
47.5%（95%CI：37.3-57.7）的患者报告了 EDS （Epworth 嗜睡量表评分>10）的抱怨。在该样本中，52.6%（95%CI：0.41-0.60）超重或肥胖，53.1%（95%CI：0.43-0.62）接受的正规教育少于 8 年。主要是焦虑，但也包括颈围，与 EDS 相关。我们的患者没有表现出定量的睡眠剥夺。其他与癫痫相关的变量与 EDS 没有关系。我们人群中 EDS 的患病率高于其他国家进行的类似研究。这一发现似乎与癫痫本身无关，而是与其他临床因素（如颈围）以及主要的精神因素（如焦虑）有关。
焦虑等精神共病与 EDS 有关，应予以识别和治疗。需要更多基于客观睡眠质量分析的研究来帮助阐明巴西人群中的这些关系。
