The brain has a large part in the causes of of anorexia nervosa. Studies by Arline Kaplan have actually revealed neurocircuit dysregulation and has helped clarify the disorder’s confounding symptoms to this disorder. The studies have shown that insights into the ventral (limbic) and dorsal (cognitive) neural circuit dysfunction, perhaps related to altered serotonin and dopamine metabolism, may help explain why people with anorexia feel as if dieting reduces their anxiety while eating actually increases it. This is also the cause of why they worry about long-term consequences but seem immune to immediate gratification and unable to live in the moment. Personality traits can also cause the outcome of this disorder. Some examples include harm avoidance, anxiety, behavioral inhibition, difficulty with moving from one mental set to another, a tendency to focus on details rather than the big picture, and perfectionism. Even after recovery from anorexia, these traits persist. The starvation and malnutrition involved with the disorder can negatively effect the brain. Such changes include neurochemical imbalances, which can exaggerate the preexisting traits and accelerate the disease process. People with this disorder tend to have a reduced brain volume and a regression to prepubertal gonadal function. However, these disturbances tend to normalize after weight restoration, which is suggesting that these alterations are state-related. Imaging studies have shown that individuals with anorexia have an imbalance between circuits in the brain that regulate emotion and rewardand circuits that are associated with consequences and planning ahead. There has also been brain-imaging studies that show that people with anorexia have alterations in parts of the brain involving with interoceptive self-awareness that In addition, altered function of other related regions may be implicated in disturbed bodily sensations. Anorexia may may also contribute to sensing of the rewarding aspects of pleasurable foods. This is stating that people with anorexia may literally not recognize when they are hungry. http://eatingdisorders.ucsd.edu/documents/Kaplan_PsychiatricTimes.pdf
This is a very technical article and you copy/paste much information. You need to read and summarize using your own words and develop your own meanings and understandings of what you are reading. If you have questions ask...but don't cut/paste.
