We all know bulimia nervosa (BN) and binge‐eating disorder (BED) are two serious and life threatening eating disorders. These two medical conditions seriously disrupt eating behavior. That is why the eeg (Electroencephalogram) study of the patients with these conditions, become the paramount interest of the researchers.
The key onset of BN is characterized by recurrent episodes of binge eating with the association of loss of control over eating in a frequent and discrete period of time and with the extreme mindset of the weight gain prevention.
Literature Review:
In most of the studies BN used to be identified by clinical expert rating or self report.
There is a recent study [1] on Women subject suffering from BN. They were presented neutral
and chocolate stimuli (both olfactory or visual) at the time of EEG recording. Researchers found no significant frontal theta activity between these two different stimuli. And also frontal theta activity was not significantly different from healthy control for all sorts of stimuli presentation.
Thirteen overweight and obese patients with BED and thirteen overweight patients with out BED participated in the experiment. EEG activity was measured for all participants in the resting state condition. Individuals with BED displayed higher fronto‐central beta activity in the resting‐state eyes closed EEG compared with individuals without BED.
