About this study
The aim of this study was to investigate the difference between electroencephalography (EEG) data and current psychological status of individuals diagnosed with anorexia nervosa (AN) and bulimia nervosa (BN).
Read the detailed description
The data used in this study were obtained from individuals aged 18 and younger with eating disorders who applied to Üsküdar University NP Istanbul Brain Hospital. Two different diagnostic groups, Anorexia Nervosa and Bulimia Nervosa, were included in the study. Demographic information, secondary diagnosis status, Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Eating Attitude Test - 40 (EAT-40) scores and EEG data were used to investigate the differences between eating disorders. Comparison of neurological differences between individuals with AN and BN was done retrospectively.
This information, which will be obtained for AN and BN, which are diseases in which severe deterioration in behavior and perception are seen, can give advice to experts in planning treatment and rehabilitation processes.
