Continuous positive airway pressure therapy for obstructive sleep apnea reduces interictal epileptiform discharges in adults with epilepsy
Obstructive sleep apnea (OSA) is highly prevalent, affecting 25% of men and 10% of women. We recently reported a prevalence of OSA of 30% among 130 adults with epilepsy unselected for sleep disorder complaints, including 16% with moderate-to-severe disease, rates that markedly exceed general populat...

Obstructive sleep apnea (OSA) is highly prevalent, affecting 25% of men and 10% of women.
