Background/objective: Sleep-related eating disorder (SRED) may have some common clinical features with sleepwalking and with eating behavior disorders. The objective of this study was to compare clinical, sleep, and eating behavior measures in patients with SRED vs. sleepwalkers and controls. Methods: Overall, 15 patients with SRED, 21 sleepwalkers, and 20 age- and sex-matched healthy volunteers underwent interviews, completed sleep, anxiety, depression, and eating behavior scales, and had a night-time videopolysomnography. Results: Patients with SRED were mainly women, had disease onset in adulthood, suffered nightly episodes and insomnia, and had more frequent eating problems in childhood and higher current anorexia scores than sleepwalkers and controls. Unlike controls, they shared several commonalities with sleepwalkers, including a high frequency (66%) of past or current sleepwalking, a similar timing of parasomnia episodes during the first half of the night, numerous arousals from stage N3, and a similarly altered level of daytime sleepiness and anxiety, but higher awareness during parasomnia episodes. Conversely, only 10% of sleepwalkers ate during their sleepwalking episodes. On videopolysomnography, the eating episodes occurred mostly within 1 min after awakening from stage N2 (n = 9) or stage N3 (n = 6). The frequencies of restless legs syndrome, periodic leg movements, and sleep apnea were similar across the three groups. Conclusions: Patients with SRED share several clinical commonalities with sleepwalkers (although their level of awareness is higher) plus former or current eating behavior problems. It suggests that they have specialized a former sleepwalking behavior toward sleep-related eating because they are more vulnerable to eating behavior problems during the daytime.
