Abstracts

            The etiology of anorexia nervosa is indefinite. In this clinical-conceptual manuscript research, the author suggests an original hypothesis including interdisciplinary studies between his clinical practice as psychoanalyst and psychiatrist over a decade, experimental psychology and neurobiology.
He suggests that anorexia nervosa etiology is due to a traumatic experience felt by the patient with feeling of death. It is necessary a special predisposition, developed by a previous occurrence of another premature traumatic experience with the same sense of death.
These experiences trigger neurobiological innate and reflex responses of the body to maintain life and to auto appease the anguish of death that follows the traumatic experience. The first one consists in a partial return of body metabolism to its initial state, when the oxygen used by the cell was minimum for the vital cellular functions. The second is an auto generation of sensorial experiences using own body elements as fingers, urine and others in contact with the skin and others sensorial surfaces. There happens a disconnection between cortical and hypothalamic circuits.
Though this is a neurobiological hypothesis, the author consider psychoanalytic psychotherapy as central to treatment, due to the maintenance of the therapeutic setting. It allows the reconnection of the neural circuits, for the restoration of personal trust with other people and for the interpretative work of the habitual severe superego.
The author thinks that his positive clinical results with these references suggest the continuation of these studies  
























Keywords: nervous anorexia; etiology; traumatic experience; implicit memory; psychoanalytical psychotherapy.

Introduction
Anorexia nervosa is an eating disorder of varying severity. Experts in various fields do not present conclusive results about its etiology.
There are several hypotheses to explain it such as genetic 1, religious 2, hormonal 3, neurologic 4, socio-cultural 5 and psychogenic 6. These assumptions generate different therapeutic approaches. Each specialist focuses within its own framework.
The author aims to present an etiological hypothesis of biological nature linked to a traumatic experience felt by the patient with feeling of death as defined in DSM-IV 7. He emphasizes the need of predisposition raised by a previous fetal or perinatal trauma with the same sense.
These experiences trigger neurobiological innate and reflex responses of the body to maintain life and to auto appease the anguish of death that follows the traumatic experience. The first one consists in a partial return of body metabolism to its initial state, when the oxygen used by the cell to operate her vital functions is minimum 8. The second is an auto generation of sensorial experiences using own body elements as fingers, urine and others in contact with the skin and others sensorial surfaces 9. There happens a disconnection between cortical and hypothalamic circuits 10. Both may go on throughout life.
The traumatic experience may occur since the fetal period, as shown in the work done with ultrasound fetal studies 11.  
The author considers the symptoms of anorexia as biological concomitant of traumatic experience and therefore they do not have mental representation. There are not repressed elements, neither sexual nor aggressive, as psychoanalysts’ believes 6.
Although this is a neurobiological hypothesis, the author consider psychoanalytic psychotherapy as central to treatment, due to the maintenance of the therapeutic setting that allows the reconnection between the neural circuits of the hypothalamus with those of the cortex 10. It is also important for the restoration of personal trust with other people and allows an interpretative work of the habitual severe superego.
The application of these studies in my clinical practice has resulted in significant improvement of the anorexic patient and her adherence to treatment.

Method
The method used by the author is a combination of his many years of clinical practice as psychiatrist and psychoanalyst and interdisciplinary studies on post-traumatic stress disorder, experimental psychology and neurobiology.
He follows the reference of the DSM-IV 7 to diagnose anorexia:
A - A commitment of the anorexic patient to maintain body weight at least 85% below normal body weight for age and height, accompanied by an intense fear of gaining weight even though emaciated.
B - A disorder in order to experience weight loss, as no notion of slimming and denial of the risk of weight loss. In addition, the perception of distorted body image, i.e., the anorexic sees or thinks fat.
C - Women who have started their menstrual cycle have periods of amenorrhoea and menstruation appears only after administration of hormones.
The author includes in this work, the transitory cases of anorexia met in post-traumatic patients. Commonly they show loss of appetite, refusal of food, loss of weight and libido, different psychosomatic symptoms, phobias, daytime somnolence, fears, anxiety and other symptoms. They appear after the occurrence of traumatic experiences as surgery, physical violence, torture, sexual abuse, dear relative loss, marital separation, kidnapping, a forced period of overwork and other stress situations. These symptoms may be short-lived or become chronic. These patients commonly receive diagnose of depression.

The traumatic experience
There are many kinds of traumatic experiences, from biological to psychological and it may happen in any period of life, as shown.
It is possible to observe difficulties of the newborn, right after birth, to establish a healthy relationship with the mother. It happens feeding difficulties, excessive sleepiness, presence of autism early signs as continuous suction of the finger and apathetic look, a motor slowness and others that usually accompany the newborn for the end of the life 12.
These observations indicate that the traumatic experience may occur in fetal period. In the clinical experience of the author, he observed that it is possible to get from the patient or their parents history of fetal trauma. When this is not possible, the neurobiology shows 13 that the traumatic event appears in dream and can be detected with the aid of the understanding of the functioning and purpose of implicit memory in preserve our life, as chaotic dreams of falling, freezing, death, tight passages and others.
Another kind of traumatic experience is that one related to stress. In a recent study 14 with rats, the author shows clearly this relation. He used a group of rats as control group that had free access to a cage with food, attached to a wheel rim with 33 cm in circumference, around which the rats ran and another group whose access to the cage were closed certain hours of the day. After few days of alternating sessions of free access to food with restricted access in one-hour intervals, the mice lost, weight and could die, if not removed from these conditions. The author observed that as they lost weight, they run more quickly but ate less when they returned to have free access to food. This phenomenon is paradoxical, because it expects that these mice eat more as your weight decreases, but actually eat less than those used as control in the experiment eat. Experience has demonstrated that the weight loss is not associated with loss of calories per becomes more accelerated, but to an activity that includes a state of stress - or the expectation of having no access to food.
Another contribution 7 to the author’s hypothesis is an experiment on human organs, to explain the biological defence to preserve life. It aims to increase the number of hours for use of organs for transplants. He used solution of H2S, which decreases oxygen consumption by the cell to carry out the vital functions, with a damping of life to a "state of suspended animation of life". He was able to demonstrate that this process can happen in humans, activated in adverse living conditions, repeating the phenomenon of hibernation with plants and animals, allowing them to survival for decades.
Perhaps the same happens with humans, who have undergone several hours without oxygen in accidents, such as burial by ice or land. These victims like animals and plants, showed extraordinary resistance to environmental stresses such as excessive temperatures, oxygen deprivation and physical injuries. The researcher was well succeed to prolong the lifetime of various organs transplanted, performing an important achievement in organs transplants.
As described the traumatic experience also trigger a body resource to auto appease the victim.


Predisposition
Studies on posttraumatic stress 15 ​​with victims of road trauma, found that victims of serious accidents do not develop PTSD, and other victims became sick after minor accidents. In the personal history of the latest had always occurred earlier traumas.
Observations show that children, babies and animals develop anorexia when left to strangers or happens radical change in the environment. If not moved in time of such circumstances, they may die of auto inanition. However, this does not occur with all of them.
Also a study 12 shows that birth trauma can cause symptoms of neonatal immaturity at birth and source high levels of eating disorders and others no.
The author suggests that the predisposition for the development of anorexia remains in the fact of a previous fetal or perinatal traumatic experience with feeling of death. They come to the world as if they were in a fine line between life and death. This is valid to cases of transitory anorexia.
They brought with them the biological defence described to maintain alive. They run reflexively back in search of the initial metabolic rate where the cellular oxygen for its vital function is minimum. The author call this mechanism of ‘autistic retreat’ responsible for what he calls ‘the autistic personality’. Really, there are studies 16 showing the onset of symptoms of autism spectrum chronic course in anorexia.
In cases of life threatening in a posterior traumatic experience independent of age, the body of the victim moves back to that initial state of safety. This defence is similar to the mechanism of psychic regression in search of survival described by Freud 17 and illustrated by him as similar to the advancing armies that leave behind them, points of support to which they can return if necessary.
Another important contribution made by a neurobiologist 18 with the study of implicit memory, show that this works similarly to the Freudian unconscious. It is responsible for acts performed automatically, turned for survival. Thus, unlike Freud 19 that postulated the etiology of dream as result of sexual desire suppressed from daytime repression, neurobiology 13 has shown that the dream is also a neuropsychological process by which a short daytime learning related survival is transformed into a learning long term (long term memory).
The knowledge that the body has a way of relating to the environment and innate reflex manner through existing records in implicit memory, independent of our cognition, often allows anticipate the existence of a traumatic event.

Clinical cases
Case A
Julia is a beautiful woman, twenty-three years old, thin, always well dressed, intellectual and divorced. At our first meeting three years ago, she reported loss of weight since her adolescence, when she began to avoid solid food and to measure the calories ingested in an obsessive way. Since then, when she exceeded the food intake she had vomit and made use of laxative with high intake of water. She ate only chocolate. Associated with this eating disorder, she mentioned intolerance to prolonged contact with people, cold, heat or noise. She elected social isolation and has a feeling of existential emptiness. It also presents insomnia, indifference, fatigue, sleepiness daily, amenorrhoea, constipation, bruxism, sweating, salivation, difficulty in concentration and memory. She felt depressed without sadness.
She told me that when she was four years old, she was sexual abused by an uncle for two years, keeping this fact only for her because she was afraid to tell it for her father and mother. Hers symptoms became severe at the age of fourteen, when was preparing to be a model because of her thin body and facial beauty. She started with success and when she was seventeen years old was encouraged by her family to take a course in another country. She remained there a year and no longer supported the absence of the mother and of the boyfriend. After returning, she married him and set up home with furniture from the mother’s house, although the husband insisted on buying new furniture. After a few months, they separate due to the development of food obsessive ritual, menstrual dysfunction and extreme attachment and submission to the mother. The ex-husband left the apartment but returned frequently, attending to her requests.
One year later, she started to work as teacher. Soon after, she felt a compelling need to sleep in the afternoon, a fact that embarrassed her daily life. The food rituals accentuated, appeared panic attacks with fear of death and social phobia. She made ​​several psychiatric and psychological treatments with no improvement. She became suspicious with any kind of treatment and only sought me by indication of a friend, who had been my patient.
At the end of the meeting, I prescribed benzodiazepine at bedtime and proposed psychotherapy with two weekly sessions, fifty minutes each.
One month later, she reported that it was difficult to continue to work as teacher because the persons look at her in a strange way. Sometimes they avoided her because she was few communicative. She felt insufficient for physical and intellectual work but her mother insisted that she worked. She told me a dream in which she was in bed and was not breathing. She tried to move and could not. She felt powerless. She heard a voice saying to her: "They're sewing a new shirt for you. It is very tight”. She woke up feeling bad.
The session ended with her telling that her dream indicated the current physical state of failure, but brought hope of improvement with psychotherapy - the voice announcing a new shirt.
The patient comes regularly to the sessions due to my empathy with her insufficiency to deal with the family, social and professional life. Always she came to me dressed in black. Sometimes speak of her ex-husband and attachment to mother and father. Occasionally mentioned her sexual life. Unwilling to return to the traumatic experiences, as happens with posttraumatic patients, she never mention the sexual abuses by the uncle. She told me that her ​​mother pregnancy was normal, but the birth was laborious. Once, she made reference to her birth, saying that was born with blood running down her head due to the forceps and her mother spent a month without being able to take care of her due to infection of her genitals parts related to the birth. She remember that when was two years old, she had intense severe bronchial asthma that disappeared at the age of eight years.
After three months of psychotherapy, she was still in state of failure and stress and in a session, reported a dream in which her car could not go on a small rise near her home and she tried to push it but felt powerless.
After one year, the patient arrives and I notice that she is more colourful and the timbre of the voice stronger. She told me that her weekend was good. She went with her new boyfriend with whom is living and entered the water only once because it was cold, but was happy to wear costume bath. She also told me that felt she did not live, only existed, and all mechanical.
One year later, she told me she is living without fear of vomiting and is planning a trip to the home of her boyfriend's parents, not being carried by the tendency to stay at least as she did to feed and to live. She remains in psychotherapy.

Case B
Another patient shows a weight loss of eleven pounds since two years ago, after the death of her husband, staying alone. Her doctor have raised suspicion, to explain this weight loss, of the existence of an undiagnosed cancer. She then underwent a complete check-up to exclude its presence and now she was going again to submit a second battery of exams as colonoscopy and breast and brain scan for the sake of conscience of her clinic. The doctress certainly considered only the weight loss resistant to usual medical treatment and did not take into account her memory loss, her daytime sleepiness and other symptoms indicative of her posttraumatic stress. Because of loneliness and medical mistakes, the patient presents squizoparanoide ideas. Her son brought her to me. I prescribed antipsychotic (risperidone), benzodiazepine and antidepressant. She began psychoanalytic psychotherapy twice a week, attending regularly to the sessions accompanied by a relative for the fear of going out alone at the street and your state of muscular weakness. After a month, improved psychotic symptoms began to sleep better and their relatives informed me that she was more active.
In the initial sessions, she kept her focused on physical complaints, but gradually was encouraged to talk about their losses and dreams. The author think the patient would not be in psychotherapy longer, because soon started talking about reduce the sessions. This moment he remembered that these patients wants soon as possible to come back for themselves. The author showed this for her and she considered continuing. She became dependent of him as important for her sake. After six months, she began to show improvement in appetite, weight loss and sleep with the absence of any psychotic symptom.

Case C
Another patient presenting progressive weight loss comes seven months with loss of eight pounds, after the arrest of his son on charges of drug trafficking. At the beginning I did not understand why psychotherapy, but gradually was adhering to treatment because of the improvement occurred. The author used only as an aid benzodiazepine treatment.

Conclusion
The anorexic patient is a difficult clinical management because she worries with her delicate balance between life and death. As consequence of the troubled relationship with her mother since birth, she grows up without finding an enabling environment to heal the disconnect cortex-hypothalamus circuits11.
The author emphasizes that psychoanalytic psychotherapy is the most important element in her treatment. It has a constant setting maintained with usual consistence. She needs an emphatic caretaker with sensibility to countertransference phenomenon in order to achieve her appeasement and confidence in other people.
This patient usually presents an insufficiency for her family, professional, social and affective relations that generates many criticisms. She internalizes these and becomes an important factor for intensification of her fears, failure and stress responsible by the burnout. We have to elaborate with her the charges of her superego by an interpretive work.
The author concludes that anorexia is an organism attempt conducted by the cerebral amygdala to survive, although it approaches the patients to death, which is another paradox. The body becomes a “sufficient good mother”20.  
This paper is a preliminary communication. The author suggests its continuation due to his satisfactory clinical results.
