Neurobiology of Eating Disorders: Clinical Implications

Anorexia nervosa AN is classically defined as a condition in which an abnormally low body weight is associated with an intense fear of gaining weight and distorted cognitions regarding weight, shape, and drive for thinness. This article reviews recent evidences from physiology, genetics, epigenetics, and brain imaging which allow to consider AN as an abnormality of reward pathways or an attempt to preserve mental homeostasis. Special emphasis is put on ghrelino-resistance and the importance of orexigenic peptides of the lateral hypothalamus, the gut microbiota and a dysimmune disorder of neuropeptide signaling. Anorexia nervosa AN is an eating disorder defined as an abnormally low body weight associated with intense fear of gaining weight and distorted cognitions regarding weight, shape, and drive for thinness American Psychiatric Association, This disorder has a month prevalence rate of 0. The research on anorexia nervosa has historically focused on pituitary glands Gull, , psychiatric aspects associated with a minimum of 12 kg voluntary loss Bliss and Branch, , or hormones such as oestradiol, progesterone, and LHRH Boyar et al. But with the progress of brain imaging techniques especially functional MRI , GWAS and epigenetic approaches, animal models, discovery of neuropeptides such as 26RFa , and increased knowledge in the role of gut microbiota, it now appears possible to propose more comprehensive models of AN, which also take into account the improved knowledge of psychological risk factors during or even before childhood, and the new insights given by the high psychiatric co-morbidity rate of AN.

New insights into neural pathways that play a role in anorexia nervosa, bulimia nervosa, and binge eating disorder. Eating disorder behaviors can range from dangerous caloric restriction to eating that feels out of control-often combined with unhealthy weight control behaviors, such as self-induced vomiting or laxative abuse. Anorexia nervosa, bulimia nervosa, and binge eating disorder are the most prevalent eating disorders. Criteria for bulimia nervosa include recurrent binge eating eating a large amount of food in a discrete period of time accompanied by a sense of loss of control and actions meant to counteract weight gain eg, self-induced vomiting , as well as overvaluation of body weight or shape. Binge eating disorder involves recurrent binge eating without inappropriate compensatory behavior. Individuals with eating disorders frequently report extreme body dissatisfaction, anhedonia, anxiety, and difficulty tolerating negative emotions, although these are not required for diagnosis. The cause of eating disorders remains unknown.

Individuals with anorexia nervosa AN exhibit an ego-syntonic resistance to eating and a powerful pursuit of weight loss, yet are paradoxically preoccupied with food and eating rituals to the point of obsession. Moreover, these individuals have a distorted body image and, even when emaciated, tend to see themselves as 'fat', express denial of being underweight and compulsively over-exercise.

 Итак, внизу у нас погибший Чатрукьян, - констатировал Стратмор.  - Если мы вызовем помощь, шифровалка превратится в цирк. - Так что же вы предлагаете? - спросила Сьюзан. Она хотела только одного - поскорее уйти. Стратмор на минуту задумался. - Не спрашивай меня, как это случилось, - сказал он, уставившись в закрытый люк.  - Но у меня такое впечатление, что мы совершенно случайно обнаружили и нейтрализовали Северную Дакоту.

Ведь если кто и может справиться с возникшей опасностью, да еще без посторонней помощи, так это Тревор Стратмор. Он обладал сверхъестественной способностью одерживать верх над всеми, кто бросал ему вызов. Шесть месяцев назад, когда Фонд электронных границ обнародовал информацию о том, что подводная лодка АНБ прослушивает подводные телефонные кабели, Стратмор организовал утечку информации о том, что эта подводная лодка на самом деле занимается незаконным сбросом токсичных отходов. ФЭГ и экологи так и не смогли установить, какая из двух версий соответствует истине, и средства массовой информации в конце концов устали от всей этой истории и перешли к другим темам. Каждый шаг Стратмора был рассчитан самым тщательным образом.
