The aim of this study is to report current clinical practice for sleep induction in Italian epilepsy centers. We administered an online-structured survey between March and November 2017 and collected data from pediatric and adult neurophysiologists belonging to 73 epilepsy centers. The preferred time for EEG recording is variable, depending on daily schedule of each laboratory. To facilitate spontaneous sleep during nap EEGs, almost all centers require sleep deprivation before the examination, with partial loss preferred to total deprivation in most centers (58/73 vs 12/73, p < 0.001). Other non-pharmacological procedures include breast/bottle feeding or listening to music (encouraged in most centers). Pharmacological sleep induction is performed in 40% of laboratories, more commonly in children than in adults (27/60 vs 7/42, p = 0.003). Melatonin is the most frequently prescribed drug to facilitate spontaneous sleep (one third of participating centers). Our study highlights the great heterogeneity among Italian epilepsy centers in current clinical practice for sleep EEG recordings. Expert consensus for sleep induction procedure is warranted.
