What is the relationship between anorexia nervosa and bulimia nervosa?
The main difference between diagnoses is that anorexia nervosa is a syndrome of self-starvation involving significant weight loss of 15 percent or more of ideal body weight, whereas patients with bulimia nervosa are, by definition, at normal weight or above.
What part of the brain is associated with anorexia nervosa?
Most fMRI studies performed in patients with anorexia nervosa focused on food, taste, physical appearance and social cognition. Although very different in terms of the study protocol, the most common findings are increased activation of the amygdala and altered activation of the cingulate cortexcingulate cortexThe cingulate cortex is a part of the brain situated in the medial aspect of the cerebral cortex. The cingulate cortex includes the entire cingulate gyrus, which lies immediately above the corpus callosum, and the continuation of this in the cingulate sulcus.https://en.wikipedia.org › wiki › Cingulate_cortexCingulate cortex – Wikipedia.
Does anorexia cause permanent brain damage?
Brain scans of people with anorexia reveal that the brain goes through structural changes or abnormal activity during the disease. Some of these abnormalities may discontinue weight restoration, but some of the damage to the brain can be permanent.
