A pre-post design including 22 females was used to evaluate the effectiveness of neurofeedback in the treatment of adolescent anorexia nervosa. Resting EEG measures and a psychological test-battery assessing eating behavior traits, clinical symptoms, emotionality, and mood were obtained. While both the experimental (n = 10) and control group (n = 12) received their usual maintenance treatment, the experimental group received 10 sessions of individual alpha frequency training over a period of 5 weeks as additional treatment.
Background: Patients with anorexia nervosa (AN) are more emotionally involved with food stimuli (Giel et al., 2011). More emotional arousal is associated with higher amplitudes of evoked potentials in the EEG (Cuthbert et al., 2000). Objective: Investigation of neural correlates measured by EEG (visually evoked potentials) that are associated with the reactions to food and emotional stimuli in AN patients. Methods: 13 AN patients and 13 healthy controls watched food and emotional pictures during EEG measurement.
