A quantified analysis of sleep electroencephalography in anorectic adolescents

Effects of sweet and bitter gustatory stimuli in anorexia nervosa on EEG frequency spectra

“…The possibility of long lasting effects of malnutrition is further supported by non-linear analysis of the same data, which revealed decreased dimensional complexity of the EEG in AN patients, independent of taste conditions (Toth et al, in press). Nobili et al (1999) found a positive correlation between body mass index and the amount of slow wave activity in AN patients.…”

Sleep disturbances in anorexia nervosa

“…Some studies report minimal or no sleep disturbances (Latzer, Tzischinsky, & Epstein, 2001;Lauer, Krieg, Riemann, Zulley, & Berger, 1990;Lauer, Zulley, Krieg, Riemann, & Berger, 1988;Pieters et al, 2004), while others describe important sleep disturbances (Bos et al, 2013;Delvenne, Kerkhofs, Appelboom-Fondu, Lucas, & Mendlewicz, 1992;Kim et al, 2010;Lacey et al, 1975;Levy, Dixon, & Schmidt, 1987Nobili et al, 1999;Walsh, Goetz, Roose, Fingeroth, & Glassman, 1985).…”

Growth Hormone-Insulin-Like Growth Factor-1 Axis, Leptin and Sleep in Anorexia nervosa Patients

“…In a study by Nobili et al [22], delta power was decreased in young girls with AN. In the present study, the theta power was significantly decreased in anorectics as compared with controls, while the lower values in delta power were not significant.…”

“…Anorectics have been described to have shorter total sleep time, less nonREM efficiency, and more stage 1 sleep than controls [20]. They also tend to have less SWS [21], and a positive correlation between the body mass index (BMI) and the amount of slow-wave activity in the delta range (0.5-4.5 Hz) has been reported [22].…”
