Identifying obstructive sleep apnea in patients with epilepsy: a cross-sectional multicenter study

Obstructive sleep apnea (OSA) is a breathing disorder characterized by intermittent narrowing or collapse of the upper airway during sleep[1]. The prevalence estimates of OSA in patients with epilepsy vary widely, ranging from 10% to 88.9%[2–3]. The risk factors for OSA in patients with characteristics of epilepsy have not been identified conclusively. Data on the association between risk of OSA and disease characteristics and AED use in patients with epilepsy with epilepsy are very limited. A study from the Cleveland Clinic showed that among adults with epilepsy OSA was associated with higher AED load[4].
