Obstructive sleep apnea (OSA) may occur in up to 30% of patients with epilepsy.1 Excessive sleepiness, such as that seen in OSA, lowers the seizure threshold, and treatment of OSA with continuous positive airway pressure (CPAP) appears to decrease seizure frequency in patients with epilepsy.1 A growing consensus in the epilepsy literature stresses the importance of effective OSA management in helping to control the symptoms of epilepsy. However, few studies have investigated the converse: epilepsy's effect on sleep apnea.
