In present study we analyzed visually EEG recordings of females with anorexia nervosa. 126 patients had not taken any medication for at least 2 weeks prior to the EEG examination and 52 females were treated with psychotropic drugs. Similarly, there were collected EEG recordings of females with bulimia nervosa, among them 82 EEG recordings of non-medicated patients and 36 of treated ones with psychotropic drugs. All recordings were estimated with regard to presence of abnormalities, their type, localization and intensity.
In the group of patients with anorexia nervosa there were observed significantly more abnormal EEG examinations than within the group with bulimia nervosa. Moreover, in females with anorexia the abnormalities in EEG were more pronounced, with epileptiform discharges and right hemisphere lateralization.
