(Licheni et al. 2017) 57 patients from Australia completed a sleep questionnaire, with 75% reporting problems. The most commonly reported problem was difficulty initiating and maintaining sleep, with sleep-wake transition disorders second most common. 53% had nocturnal seizures.
16 patients were monitored by pulse oximetry overnight, and 14 of those had a higher than normal oxygen desaturation index, though this may be indicative of nocturnal seizures.
